Along with interdisciplinary dialogue, Eghigian told The Debrief that another aim of the Society’s event involves another of the subject’s most enduring problems.

“Speculation about UAP is often unmoored from any empirically sound and self-critical research,” Eghigian said. “The conference seeks to address this shortcoming by placing multidisciplinary scholarship about the subject center stage.”

Along with Peters and Eghigian’s workshop, several others that address various approaches toward studying UAP will be featured, including a session that focuses on the application of citizen science.

“The UAP Citizen Science Workshop is bringing together scientists from the UAP field and surveying the available resources and best practices for citizen science in general,” said Dan Williams, who coordinates the Society’s official Citizen Science Working Group.

Williams, who will lead the workshop, says such resources include SciStarter, Zooniverse, the NASA Citizen Science Seed Funding Program, commercial satellite Earth Observation imagery and analytics, ground-based instrumentation, smartphone apps, and self-supervised machine learning, or what he calls “needle-in-a-haystack” technologies.

“We hope the workshop participants can then author a paper on best practices and identify several citizen science projects of general interest. We have several members from the recent National Science Foundation’s ASTRO-ACCEL-sponsored UAP workshop participating, and we hope our workshop also advances their goal of forming a UAP citizen science working group,” Williams told The Debrief.

“The study of UAP deals with incomplete, inaccurate, and even at times deceptive information,” said Joshua Pierson, D.S.S., a career investigator who is also an advisor to the Society for UAP Studies. “The beauty of having a conference and an organization that focuses on bringing the social sciences and the humanities to bear is really where we start being able to assess what is inaccurate and incomplete,” Pierson said.

“Except now, instead of taking a practitioner’s approach, we have people who can think deeply on the subject to help inform some of the best models and methods to approach the information that we get on UAP,” Pierson told The Debrief.

Pierson says that in addition to applying the best models and research methods, a collective aim of academic groups like the Society for UAP Studies is also to define the phenomena more accurately. However, along with framing the phenomenon in academic terms, part of the aim of studying UAP from a humanities perspective also involves recognizing how people relate to UAP experiences and what overall impact the subject has on individuals, as well as at the societal level. 

“UAP have profound effects on the lives of those who witness them, and they also stimulate important questions about the nature of knowledge itself and the limitations of ourselves as knowers,” said Dr. Kim Engels, an Associate Professor of Philosophy at Molloy University who is also on the Society’s Advisory Board. “Our conference is offering a space for philosophers and theologians to weigh in on these important dimensions of the UAP conversation.”

“One of the most important things I think the humanities supplies—at least the philosophy of science, my own tradition—is a sort of critical perspective on the ways in which people have come to interpret and study UAP,” Professor Cifone told The Debrief.

“I think we’re at an interesting moment here in terms of the science of UAP. There’s a kind of a turning point right here that I think we’re witnessing, and a science is forming out of a history of kind of abortive and failed attempts to bring to bear some kind of systematic scientific engagement with the question,” Cifone said.

If Cifone is correct, and the efforts by organizations like his, as well as those currently being undertaken by other academic groups and government agencies, are pointing to the emergence of a new area of study in the sciences, then groups like the Society may be some of the best-equipped to help guide the process.

“You know, there’s this in-between space that I think the humanities is really good at negotiating,” Cifone told The Debrief, adding that academics like those who will participate in the Society’s forthcoming conference could be particularly well suited to help the scientific community navigate the various challenges presented by such a complex field of study.

“This is, I think, where humanists can bring the scientists together,” Cifone said, “to discuss that kind of a difficult aspect to the phenomenon.”

The Society for UAP Studies will hold its online Summer Conference 2024, titled “Varieties and Trajectories of Contemporary UAP Studies,” from August 16 to August 18, 2024. Registration details and other information about the event can be found on the Society’s website.

US Military Recovered UFO That ‘Distorted Space-Time’ & Craft Able To ‘Alter Our Reality’ As Mentioned In Bizarre Navy Docs

Physicist Michio Kaku proposes the existence of other dimensions, also known as parallel universes, coexisting alongside our own reality. Within these dimensions, it is plausible that there are beings or entities living alongside us, despite our inability to perceive them. While the concept of alternate dimensions or universes may seem far-fetched to some, it is intricately connected to the subject of Unidentified Aerial Phenomena (UAPs), commonly referred to as UFO phenomena.

We live in a four-dimensional world (if time is included), but scientists propose there are more dimensions. However, they do not believe there can exist more than 11 dimensions because conditions become unstable and particles naturally collapse back down into 10 or 11 dimensions. The 12th dimension, for example, introduces a second time.

“Our understanding of reality is not complete, by far,” says Stanford University physicist Andrei Linde. “Reality exists independently of us.” If they exist, those universes are separated from ours, unreachable and undetectable by any direct measurement (at least so far). And that makes some experts question whether the search for a multiverse can ever be truly  scientific.

In the realm of  science, our quest for understanding alternate or higher dimensions remains ongoing. However, within the field of UFOlogy, intriguing cases have emerged suggesting the existence of not just other dimensions, but also the presence of entities residing within them. These beings seem to possess the ability to manipulate a bridge connecting their realm to ours, enabling them to embark on regular visits to our world.

Crashed UFO that ‘distorted space and time’

A very strange UFO case has been shared by American attorney Daniel Sheehan with Daily Mail. Sheehan involved in bringing UFO whistleblowers to Congress, claimed that a whistleblower told him a mind-boggling tale about a recovered crashed UFO. He revealed that a crashed UFO recovered by the US military had distorted space-time and was “bigger on the inside.” The whistleblower has reportedly briefed Senate Intelligence Committee staff on the matter.

According to Sheehan, one of the alleged recoveries described by the insider involved a 30-foot saucer partially embedded in the earth. When attempts were made to remove it using a bulldozer, the craft exhibited unusual behavior. As it was being pulled out, it seemingly detached in a pie slice-shaped section, suggesting that it was constructed in a unique way.

The anonymous whistleblower then entered the craft and was astonished to find that the interior was as large as a football stadium, while the exterior was only about 30 feet in diameter. The experience inside caused disorientation and nausea due to the vast size discrepancy. Furthermore, upon exiting the craft in a few minutes, the whistleblower found that four hours had passed outside, indicating time distortion as well.

Sheehan mentions that the craft’s distortion of space and time is consistent with the theories proposed by physicists regarding advanced propulsion systems. These theories suggest that warping space-time could be used to counteract the effects of gravity and achieve advanced forms of propulsion. However, Sheehan does not provide further specific details, such as the location or date of the incident, and admits to being unable to provide concrete evidence to support these claims.

Moreover, on Jesse Michels’ show, astronomer and UFO researcher Jacques Vallee discussed another UFO case that includes experiencing another dimension by the witness. Valle said: “There was one case in San Jose. A woman had seen something over her house. It was a big disc, and I say, ‘How big was it?’ And she says, ‘Well, it was about the same size as her house. It was, you know, just like that.’ Then I say, ‘Well, when you went inside, you said, uh, you know, there was this being, and the being took you on a staircase.’ I say, ‘Where did the staircase go?’ Well, the staircase went up the side of this big round room. I say, ‘How would you compare it?’ Well, like a movie house, you know, like an M5 theater. I said, ‘That’s bigger than your house.’”

Luis Elizondo, the man who managed the UFO program inside the Pentagon, explains how space-time distortion works and hints that we can manipulate this physics for technological advancement. In an interview with George Knapp in 2018, Elizondo explains:

“Space-time is something we observe in the natural world all the time, especially in relation to gravity and GPS satellites. The clocks on these satellites need constant calibration. Even though the clocks on the satellites are identical to the ones on the ground station, they still require regular calibration. The reason for this is the effect of Earth’s gravity on space-time. The clocks on Earth run slightly slower compared to the clocks on the platforms above Earth.

How is this possible if the clocks are the same? Well, it’s because the closer you are to a massive object, like Earth, the more space-time warps. This phenomenon is explained by the theory of general relativity, which boils down to using the equation E=mc². Essentially, it means that a significant amount of mass or energy warps space-time. When you approach a supermassive object like the sun, the distortion becomes even greater. In fact, near a black hole, time becomes so distorted that it virtually stops.

We have observed this phenomenon through gravitational lensing when studying distant galaxies. We can actually see the effects of gravity on space-time with our own eyes, so it’s a  scientific fact, not fiction. The question now is how we can manipulate this physics for technological advancement. Potentially, we could warp space-time in a way that allows us to travel from point A to point B more quickly.”

Is it possible that an advanced extraterrestrial civilization has already accomplished this kind of technology and has been using it to visit our world? Or perhaps we already have such technology?

In 2021, leaked documents revealed that the US Navy had conducted experiments on various far-fetched technologies, including a “space modification weapon.” These documents, disclosed by The War Zone, detailed the research carried out by the Naval Air Warfare Center Aircraft Division (NAWCAD) between 2017 and 2019. The most interesting thing is that the technology written in those documents discusses propulsion system that defies gravity, or to devastating weapons that bends the laws of physics and craft that alters the fabric of time and space.

The man behind all the patents is Dr. Salvatore Cezar Pais, who is an aerospace engineer at the Naval Air Warfare Center Aircraft Division (NAWCAD). He has four patents registered in his name that contain the source of technology that would change the world. In these patents, a “Spacetime Modification Weapon” (SMW, a weapon that can make the Hydrogen bomb seem more like a firecracker, in comparison) is mentioned.

Are these patents a cover for the reverse-engineered extraterrestrial technology? The Navy’s objective in testing this conceptual system was to keep pace with similar programs being developed in China. The researchers believed that the space modification weapon could revolutionize power and propulsion systems. The technology was based on the “Pais effect” aimed to push the boundaries of  science.

Pais made ambitious claims about the potential of this technology, suggesting that it could lead to a propulsion system defying gravity or devastating weapons that bend the laws of physics. He even outlined plans for a “hybrid aerospace-underwater craft” capable of altering the fabric of time and space.

The Navy’s aerospace research enterprise supported Pais’s patents, stating that they filed them to keep up with similar technological advancements being pursued by the Chinese military. The “space modification weapon” described in the documents was envisioned to release extremely high energy levels, surpassing the destructive power of a Hydrogen bomb.

However, the experiments conducted between 2017 and 2019 were inconclusive. The elusive Pais effect was neither observed nor disproven during this period. The Pais effect refers to a theoretical physics concept that involves the controlled movement of highly electrically charged matter. If proven possible, it could enable the creation of powerful energy fields capable of fundamentally engineering the fabric of reality.

It is unclear whether the US Navy is continuing its experiments on the Pais effect or if the project has been discontinued entirely. None of the futuristic technologies described in the leaked UFO patents were developed, leaving the ultimate fate of the space modification weapon and related concepts uncertain.

Vreemde formaties ontdekt op Antarctica onder een 350 meter hoge gletsjer: “het lijken wel kunstwerken”

door Janine

Anna Wåhlin/University of Gothenburg

Ondanks tientallen jaren onderzoek blijft Antarctica een van de meest mysterieuze plekken op aarde en tegelijkertijd de sleutel tot een beter begrip van bepaalde fenomenen die onze planeet beïnvloeden. Een van de meest bestudeerde kwesties betreft het smelten van de Antarctische gletsjers en de mogelijke stijging van het zeeniveau. Onlangs nog is een wetenschappelijke expeditie erin geslaagd om het onderwatergedeelte van een 350 meter dikke ijsplaat te onderzoeken en daarbij onverwachte formaties te vinden die “op kunstwerken lijken”. Laten we eens kijken wat dat betekent!

Meer dan 1000 kilometer onder een ijsplaat

Filip Stedt/University of Gothenburg

Er zijn verschillende redenen om een ijsplaat op Antarctica van dichterbij te bekijken, en dan met name de Dotson-ijsplaat. Deze enorme drijvende ijsmassa, ongeveer 350 meter dik en met een diepe holte eronder, is al bekend bij onderzoekers, vooral vanwege de invloed die het kan hebben op de zeespiegelstijging. Toch is de meest recente verkenning eerder uniek dan zeldzaam: wetenschappers gebruikten een onbemande onderzeeër en reisden meer dan 1.000 kilometer in de holte. Met verbazingwekkende resultaten.

Dankzij de verkenning van de Dotson-ijsplaat bevestigden de onderzoekers hypotheses over het smelten van ijs, dat veel sneller gaat waar er meer onderwaterstromingen zijn. Wat het team van wetenschappers echter verbaasde, was een andere ontdekking met betrekking tot de basis van de gletsjer: in plaats van er glad uit te zien, zijn er verschillende formaties te zien die lijken op reliëfs, valleien en zandduinen. Maar waar hangt dat van af?

Het bestuderen van het smelten van gletsjers op Antarctica

Anna Wåhlin/Science Advances

In afwachting van meer informatie over de formaties op de bodem van de Dotsonijsplaat, kunnen onderzoekers alleen maar speculeren. Niemand had ooit een basis verwacht die zo rijk is aan details en bijzonderheden, zoals Karen Heywood, co-auteur van de studie gepubliceerd in Science Advances, ook erkent:

Het was een spannend project om aan te werken. Toen Anna [Wåhlin] de eerste afbeeldingen van de onderkant van de Dotson-ijsplaat stuurde, waren we enthousiast: niemand had het ooit eerder gezien. Maar we waren ook verbijsterd: er zaten scheuren en draaikolken in het ijs die we niet hadden verwacht. Het leek meer op een kunstwerk!

Op dit moment wordt gedacht dat deze formaties afhankelijk kunnen zijn van de onderliggende waterstromen, die op hun beurt worden beïnvloed door de rotatie van de aarde, maar het is nog te vroeg om daar uitspraken over te doen. Tegelijkertijd hebben onderzoekers enkele antwoorden gevonden over de Antarctische ijsplaten en hoe smeltende gletsjers hun veranderingen beïnvloeden.

Toekomstperspectieven

Filip Stedt/University of Gothenburg

Dankzij de kartering uitgevoerd door de onbemande onderzeeër Ran erkenden onderzoekers de behoefte aan nieuwe hypothesen over het smelten van gletsjers. Antarctische ijsplaten spelen een overheersende rol in deze verschijnselen, maar ze doen dit op basis van nog onbekende processen. Dankzij de verkenning van de Dotson-ijsplaat zijn er al veel gegevens verzameld, maar het zal noodzakelijk zijn om te wachten met het verzamelen van nieuwe: tijdens een missie raakte Ran verdwaald op de bodem van de holte. Volgens Anna Wåhlin, hoofdauteur van het onderzoek,

we hebben niet alles gekregen waar we op hoopten. Deze wetenschappelijke vooruitgang werd mogelijk gemaakt dankzij de unieke onderzeeër Ran. Dit onderzoek is noodzakelijk om de toekomst van de Antarctische ijskap te begrijpen, en we hopen Ran te vervangen en dit belangrijke werk voort te zetten.

Tot op de dag van vandaag blijft Antarctica een van de meest mysterieuze gebieden van onze planeet en toch een fundamentele plek voor wetenschappelijk onderzoek. Resultaten zoals die door wetenschappers dankzij Ran zijn verkregen, vertegenwoordigen een ongelooflijk eindpunt, maar laten tegelijkertijd zien wat het te volgen pad is. En die moet worden afgelegd op ijsplaten... of zelfs daaronder.

Researcher Jean Ward, while analyzing a Mars image acquired by NASA's Mars Reconnaissance Orbiter on March 2, 2010, discovered an unusual anomaly in Noachis Terra, a region of Mars north of Asimov, also known as the "Land of Noah." 

Using Topaz Labs' Gigapixel to upscale the image for better detail, Ward observed the anomaly, measuring approximately 250 to 300 meters in length, resembles what looks like an artificially created structure with multiple right angles. Ward suggests it could outline a 'tanker-shaped' anomaly. 

Some suggest that the anomaly could be part of an ancient road with a wall and might be part of a longer route that has been partially covered by landslides or other natural occurrences but others say that it is only the wall that stands out supporting the theory that it could be the upper part of an underground base built at/inside the rim of a crater. 

Just imagine if it is an underground Mars base, the location would be suitable for UFOs to take off or land on landing pads inside the crater, which are connected to the base. This would not be the first time UFOs have been observed descending into or taking off from craters. 

Whatever its origin, this anomaly does not appear to be a natural formation.

Object Sighted Over City in Brazil Riles Up UFO Fans

Two videos show a triangular object in the skies over the city of Curitiba, a hot spot for UFO sightings.

By Jose Antonio Lanz

Image created by Decrypt using AI

A bizarre aerial phenomenon captured on video over Curitiba, Brazil is the latest to capture the attention of “ufologists,” people who track sightings of unidentified flying objects as evidence of alien visitors. A pair of videos uploaded to YouTube shows a triangular object hovering in the sky above the southern Brazilian city from different angles.

The first, shot by Zona Desconhecida, has garnered over 31,000 views since it was uploaded on July 21. As the camera zooms in, the object appears to sport a chassis-like landing gear that vanishes later in the clip. The videographer initially dismissed it as a drone, but the lack of visible propellers and its peculiar trajectory quickly dispelled that notion.

A second video provides an even clearer view of the enigmatic craft, revealing seemingly transparent or shiny sides and a shape that subtly morphs mid-flight. The footage has racked up over 25,000 views on YouTube and spread like wildfire across other social media platforms, with some breathlessly declaring it "the clearest UFO video in history."

Armchair analysts have pored over every frame, noting how the object appears to inflate and deflate as it moves. This observation has sparked wild speculation, with some suggesting it could be a biological ship, a multidimensional living entity, or—of course—an alien spacecraft.

But some internet sleuths claim the object is simply a massive star-shaped balloon, attributing the "landing gear" to image distortion caused by the camera angle. Skeptics also counter that the video quality—however lauded by some—is insufficient to draw definitive conclusions.

The object's shape and movement certainly bear a striking resemblance to oddly shaped balloons that have been launched in Brazil before. A video from January 11, 2013, shows Brazilians releasing similar balloon-like objects into the sky.

According to local media, the Brazilian Air Force has reportedly been unable to verify the images. The agency did not immediately respond to a request for comments from Decrypt.

This latest incident adds another chapter to Curitiba's history with unexplained aerial phenomena. The city, with a population of 1.7 million people, holds the distinction of having the most UFO sightings in Brazil, according to declassified government records. Between 1952 and 2022, at least 861 UFO sightings were logged across Brazil, with Curitiba accounting for a whopping 80 of those reports.

One of Brazil's most infamous UFO encounters occurred on May 19, 1986, when multiple sightings were reported across several locations in a single night.

The event was significant enough to prompt the Brazilian Air Force to hold a press conference, during which a Brigadier famously stated, "It's not a question of believing or not [in aliens]. We can only give technical information. There are several hypotheses. Technically, I would tell you that we have no explanation."

Study: Dinosaur-Killing Mass Extinction Triggered Rapid Evolution of Bird Genomes

About 66 million years ago, at the end of the Cretaceous period, a 10-km-wide asteroid crashed into Earth near the site of the town of Chicxulub in what is now Mexico. The impact eradicated roughly 75% of the animal and plant species on Earth, including whole groups like non-avian dinosaurs and ammonites. New research has identified important changes in birds’ genomes sparked by this end-Cretaceous mass extinction, ultimately contributing to the incredible diversity of living birds.

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds.

“By studying the DNA of living birds, we can try to detect patterns of genetic sequences that changed just after one of the most important events in Earth’s history,” said University of Michigan’s Dr. Jake Berv.

“The signature of those events seems to have imprinted into the genomes of the survivors in a way that we can detect tens of millions of years later.”

A living organism’s genome comprises four nucleotide molecules, referred to by the letters A, T, G and C. The order of these nucleotides in a genome defines the blueprint of life.

The DNA code can sometimes evolve in a way that shifts the overall composition of DNA nucleotides across the whole genome.

These compositional changes are crucial in determining what kind of genetic variation is possible, contributing to an organism’s evolutionary potential, or its ability to evolve.

Dr. Berv and colleagues found that the mass extinction event sparked shifts in nucleotide composition.

They also found that these shifts seem to be connected to the way birds develop as babies, their adult size and their metabolism.

For example, within approximately 3 million to 5 million years of the end-Cretaceous mass extinction, surviving bird lineages tended to develop smaller body sizes.

They also changed how they developed as hatchlings, with more species becoming ‘altricial.’

“This means they are still very embryonic when they hatch, need their parents to feed them, and can take weeks to fledge,” Dr. Berv said.

“Birds that hatch ready to fend for themselves, like chickens and turkeys, are called ‘precocial’.”

“We found that adult body size and patterns of pre-hatching development are two important features of bird biology we can link to the genetic changes we’re detecting.”

“One of the most significant challenges in evolutionary biology and ornithology is teasing out the relationships between major bird groups — it’s difficult to determine the structure of the tree of life for living birds.”

Over the past 15 years, researchers have been applying increasingly large genomic data sets to try to solve the problem.

Previously, they used genomic data to study the evolution of birds’ genomes using statistical models that make strong assumptions.

These traditional models allow researchers to reconstruct the history of genetic changes, but they typically assume that the composition of DNA, its proportion of A, T, G and C nucleotides, does not change across evolutionary history.

The study authors developed a software tool to more closely track DNA composition over time and across different branches of the tree of life.

With this tool, they were able to relax the assumption that the composition of DNA remains constant.

“This allowed the model of DNA evolution to vary across the evolutionary tree and identify places where there was likely a shift in DNA composition,” said University of Michigan’s Professor Stephen Smith.

“For this new research, these shifts were concentrated in time, within about 5 million years of the end-Cretaceous mass extinction,” Dr. Berv added.

This approach also allowed the team to estimate which bird traits were most closely associated with these shifts in DNA composition.

“This is an important type of genetic change that we think we can link to the mass extinction event,” Dr. Berv said.

“As far as we know, changes in DNA composition have not been previously associated with the end-Cretaceous mass extinction in such a clear way.”

“We know that mass extinction events can dramatically affect biodiversity, ecology and organismal form,” said University of Cambridge’s Professor Daniel Field.

“Our study emphasizes that these extinction events can actually influence organismal biology even more profoundly — by altering important aspects of how genomes evolve.”

“This work furthers our understanding of the dramatic biological impacts of mass extinction events and highlights that the mass extinction that wiped out the giant dinosaurs was one of the most biologically impactful events in the entire history of our planet.”

By relaxing the typical assumptions used in evolutionary biology, the researchers are building more nuanced insight into the sequence of events that occurred in the early history of birds.

“We have typically not looked at the change in DNA composition and model across the tree of life as a change that something interesting has happened at a particular point of time and place,” Professor Smith said.

“This study illustrates that we have probably been missing something.”

VIDEO! AI Focuses 8 Foot Alien In Taitung, Taiwan Seen By Police Officer! UFO UAP Sighting News.

In a recent intriguing incident, a police officer in Taitung, Taiwan, reported capturing a photo of what he claimed was an alien. The photo was taken in the mountainous region of Taitung, a location requiring a government permit to access due to its remote and protected status. The officer was convinced that the blurry figure in the image was evidence of extraterrestrial life.

To verify this claim, I employed advanced AI technology designed for image enhancement and clarification. The AI tool focused on the blurry section of the photo, analyzing the shapes and patterns to bring out finer details. After the AI processing, the result was surprising: the supposed alien figure was revealed to be a tilted tree in the distance. The AI had clarified the image to show the distinctive bark texture and foliage, debunking the initial claim of an extraterrestrial encounter.

This incident highlights the power of AI in distinguishing between genuine anomalies and misinterpreted natural occurrences, providing a more rational explanation to sightings that often fuel public fascination with aliens.

Five Other Notable Alien Sightings

1. Roswell Incident (1947): Perhaps the most famous UFO incident, where an alleged flying saucer crashed in Roswell, New Mexico, sparking widespread conspiracy theories and interest in alien life.

2. Rendlesham Forest Incident (1980): A series of reported sightings of unexplained lights near RAF bases in Suffolk, England, often referred to as "Britain's Roswell."

3. Phoenix Lights (1997): Thousands of people reported seeing a V-shaped formation of lights over Phoenix, Arizona, which remains unexplained despite official explanations attributing it to military flares.

4. Belgian UFO Wave (1989-1990): Numerous sightings of large, silent, low-flying black triangles over Belgium, witnessed by civilians and tracked by radar.

5. Stephenville Lights (2008): Residents of Stephenville, Texas, observed a series of bright lights moving erratically in the sky, with some witnesses claiming to see a massive craft.

These incidents continue to capture public imagination, driving ongoing debates and investigations into the possibility of extraterrestrial life.

De eerste complexe levensvorm op aarde verscheen mogelijk veel eerder dan verwacht: de studie

door Janine

Abderrazzak El Albani/ Université de Poitiers

Een nieuwe studie heeft de opvattingen over de ontwikkeling van de eerste vormen van complex leven omvergeworpen: dit was veel eerder dan werd gedacht.

Het verschijnen van de eerste vormen van leven op aarde

Wat wordt bedoeld met complexe levensvormen? Onder deze wezens zijn er ook wezens die we tot nu toe als de eenvoudigste beschouwen. Deze laatste zijn in feite heel ingewikkeld en ondanks enorme ontwikkelingen op wetenschappelijk gebied is het nog steeds onmogelijk om ze helemaal opnieuw in het laboratorium te creëren. We hebben het over de allereerste levensvormen waarvan tot nu toe werd aangenomen dat ze lang na de vorming van de planeet zelf op aarde verschenen.

In werkelijkheid lijkt dit helemaal niet het geval te zijn: de eerste levende wezens zagen het licht toen onze aardbol zich nog in een vroeg stadium bevond, 300 miljoen jaar na zijn ontstaan 4,5 miljard jaar geleden. Dit betekent dat de aarde in zo'n korte tijd omstandigheden heeft ontwikkeld die haar gastvrij maakten voor leven. Hoewel er in de allereerste dagen van haar ontstaan geen omstandigheden op onze planeet waren die geschikt waren voor de ontwikkeling van leven, dan veranderde dat in geologische termen relatief snel.

Complexe levensvormen: ze kunnen dateren van 2,1 miljard jaar geleden

Abderrazzak El Albani

Dankzij de studie van het genoom van moderne organismen weten we nu dat de eerste vorm van leven op aarde 4,2 miljard jaar geleden ontstond. Het gaat om LUCA, Last Universal Common Ancestor, de voorouder die alle levende wezens op aarde gemeen hebben.

Nu heeft nieuw onderzoek uitgewezen dat de eerste complexe levensvormen mogelijk 1,5 miljard eerder in onze oceanen zijn ontstaan ​​dan eerder werd aangenomen. Wetenschappers dachten namelijk dat de vroegste dierlijke levensvormen dateerden van 635 miljoen jaar geleden en evolueerden tot wezens met zachte lichamen in het tijdperk Ediacarium, naar schatting tussen 635 en 541 miljoen jaar geleden, als gevolg van het stijgende fosforgehalte in de zeeën. De nog niet gepubliceerde studie suggereert echter dat de vroegste vorm van complex leven veel ouder is en rond 2,1 miljard jaar geleden in het tijdscontinuüm ligt: de auteurs van de ontdekking, waaronder wetenschappers van de Cardiff University in het Verenigd Koninkrijk, vermoeden de aanwezigheid van primordiale gefossiliseerde levensvormen in sedimentafzettingen in Franceville, Gabon, Centraal-Afrika.

Geïsoleerd oceaanreservaat: was het de thuisbasis van complex leven?

Volgens het team zouden deze archaïsche levensvormen zijn uitgestorven voordat ze zich in de rest van de wereld vermenigvuldigden en ontwikkelden. De afzettingen zijn ongeveer 2,5 km dik en daarin zouden deze mysterieuze, oeroude gefossiliseerde wezens verborgen liggen. De auteurs onderzochten deze primordiale rotsformaties op tekenen van mogelijk leven in het verleden, waaronder fosfor en zuurstof: de resultaten toonden aan dat een plotselinge en grote golf geladen met fosfor een geïsoleerd deel van de oceaanbodem bereikte, waardoor een omgeving ontstond die geschikt was voor het ontstaan van primitieve levensvormen.

De concentratie van fosfor en zuurstof in de rotsen van dit oceanische reservaat zou volgens wetenschappers veroorzaakt zijn door de botsing tussen continentale platen onder water en door de activiteit van vulkanen. Dit kan een soort zee in de zee hebben gegenereerd die ondiep is en rijk aan voedingsstoffen die nuttig zijn voor de vorming van complex leven, zoals “koloniale macrofossielen”. De isolatie van de rest van de oceaan heeft echter de toegang tot verdere voedingsstoffen verhinderd, waardoor de ontwikkeling van deze levende wezens en hun mondiale verspreiding worden geblokkeerd.

Background on Lue Elizondo

Lue Elizondo, a former intelligence officer and director of the Advanced Aerospace Threat Identification Program (AATIP), has been at the forefront of UFO research within the Pentagon. His dedication to uncovering the truth about UAPs has earned him a reputation as a credible and influential figure in the field. His new book is expected to provide unprecedented insights into the government’s exploration of these mysterious phenomena.

Key Revelations from the Leak

1. Historic UAP Crashes and Non-Human Bodies

One of the most shocking aspects of the leak involves Elizondo’s claims about historic UAP crashes. According to Elizondo, credible sources, including those involved with AATIP, have confirmed multiple incidents where the United States recovered non-human bodies from UAP crash sites.

• Roswell and Beyond: While the Roswell incident of 1947 is the most famous, Elizondo’s book suggests that there have been other significant recoveries. For instance, a crash in Cadereyta, Mexico, in 1950 reportedly resulted in the recovery of a non-human body. Additionally, a 1989 incident in Kazakhstan involved the alleged retrieval of four non-human bodies from a large “Tic Tac” shaped craft.

These claims, if substantiated, could rewrite our understanding of human history and our place in the cosmos.

2. Technological Discoveries and Implants

Another intriguing revelation involves the discovery of implants in individuals who have encountered UAPs. Elizondo describes handling an implant removed from a U.S. military service member. The implant, resembling a microchip encased in a slimy, translucent tissue, appeared to possess its own metabolism.

• Implants and Advanced Technology: These implants may represent one of the most direct pieces of evidence of non-human technology. The book discusses how such discoveries challenge our scientific understanding and suggest a level of sophistication beyond current human capabilities.

3. UAPs as a Potential Threat

Elizondo emphasizes the potential threat posed by UAPs. Drawing on evidence from credible witnesses, videos, and performance data verified by AATIP, he argues that these phenomena could pose a real danger.

• Electromagnetic Vulnerability: Elizondo suggests that UAPs might be susceptible to electromagnetic pulses (EMPs), raising questions about how nations might respond to potential threats. However, he warns that any action against these objects could be perceived as an act of war by the entities controlling them.

Consciousness and UAPs: A Deeper Connection?

One of the most thought-provoking aspects of Elizondo’s book is the exploration of consciousness and its connection to UAPs. The book delves into the possibility that consciousness might be a fundamental force of the universe, intricately linked to these phenomena.

• Consciousness as a Universal Force: Elizondo posits that understanding UAPs may require a deeper comprehension of human consciousness. This perspective suggests that our consciousness might be part of a greater collective, interacting with UAPs on a subconscious level.
  

• Implications for Human Understanding: The idea that UAPs could be engaging with humans through consciousness opens new avenues for exploration. It raises questions about the nature of reality and our understanding of the universe.

Challenges Faced by the UFO Community

The leak of Elizondo’s book highlights broader challenges within the UFO community. Unauthorized leaks can significantly impact the reception and sales of such works, affecting authors and filmmakers dedicated to uncovering the truth.

• Industry Struggles: Filmmakers like Ron James and James Fox have faced difficulties with production companies, reflecting broader struggles in promoting UFO-related content. These challenges underscore the need for support and collaboration within the community.

Conclusion: A Call to Explore the Unknown

Lue Elizondo’s “Imminent” is set to be a landmark contribution to the field of UFO research. The leaked details offer a tantalizing glimpse into the mysteries and possibilities that lie ahead. As we approach the book’s official release, it’s clear that Elizondo’s work will continue to spark debate and inspire exploration into the unknown.

For those intrigued by the mysteries of the universe and the potential for discovering extraterrestrial life, Elizondo’s revelations serve as a call to delve deeper into the unexplained. As we stand on the brink of new discoveries, “Imminent” invites us to question our assumptions and embrace the pursuit of knowledge in the quest to understand the cosmos.

New 'quasi-moon' discovered near Earth has been traveling alongside our planet since 100 BC

Scientists recently discovered an asteroid that tags along with Earth during its yearly journey around the sun. 

Dubbed 2023 FW13, the space rock is considered a "quasi-moon" or "quasi-satellite," meaning it orbits the sun in a similar time frame as Earth does, but is only slightly influenced by our planet’s gravitational pull. It is estimated to be 50 feet (15 meters) in diameter — roughly equivalent to three large SUVs parked bumper to bumper. During its orbit of the sun, 2023 FW13 also circles Earth, coming within 9 million miles (14 million kilometers) of our planet. For comparison, the moon has a diameter of 2,159 miles (3,474 km) and comes within 226,000 miles (364,000 km) of Earth at the closest point of its orbit, according to NASA. 

2023 FW13 was first observed in March by the Pan-STARRS observatory, which is located atop the volcanic mountain Haleakalā in Hawaii. The asteroid's existence was then confirmed by the Canada-France-Hawaii Telescope in Hawaii and two observatories in Arizona before being officially listed on April 1 by the Minor Planet Center at the International Astronomical Union, a network of scientists responsible for designating new planets, moons and other objects in the solar system.

Some estimates suggest that 2023 FW13 has been Earth's cosmic neighbor since at least 100 B.C. and that the space rock will continue to follow this orbital path until around A.D. 3700, Adrien Coffinet, an astronomer and journalist who first categorized the asteroid as a quasi-moon after modeling its orbit, told Sky & Telescope.

"It seems to be the longest quasi-satellite of Earth known to date," Coffinet said.

Following 2023 FW13's initial discovery in March, space observers dug into the data and found observations of the asteroid dating all the way back to 2012, according to Live Science's sister site Space.com. 

Despite hovering relatively close to Earth, this quasi-satellite likely isn't on a collision course with our planet. 

"The good news is, such an orbit doesn't result in an impacting trajectory 'out of the blue,'" Alan Harris, an astronomer at the Space Science Institute, told Sky & Telescope. 

This is not Earth's only quasi-companion; a different quasi-satellite known as Kamo'oalewa was discovered in 2016. The rock sticks similarly close to our planet during its orbit around the sun, and a 2021 study suggested that this asteroid could actually be a fragment of Earth's moon.

Following tests at Vandenberg, the LOFTID is scheduled to be included as a secondary payload aboard NOAA’s Joint Polar Satellite System-2 (JPSS-2) satellite. The space agency hopes that current testing of the device will help gauge its capabilities for future missions, which may include the delivery of everything from future robotic explorers that will follow in the tread marks left by Perseverance to spacecraft carrying human crews.

“LOFTID is dedicated to the memory of Bernard Kutter, manager of advanced programs at ULA, who passed away in August 2020 and was an advocate for technologies like LOFTID that can lower the cost of space access,” the space agency said in a statement.

Over the last several weeks, the LOFTID underwent a complete systems test, along with several environmental tests, electromagnetic compatibility tests, and other checkups, along with match-mate testing between NASA and ULA components to help ensure that the systems can be successfully integrated prior to launch.

Following testing, the heat shield (also called an aeroshell) was fully inflated under conditions that replicated its orbital deployment environment, after which it underwent laser-assisted measurements before being repackaged for launch.

The LOFTID will be carried to space on board a United Launch Alliance (ULA) Atlas V rocket, after which its inflation mechanism will be deployed. Then, traveling at speeds nearing 5 miles per second, the inflatable heat shield will be tested on whether it can withstand the tremendous pressures of re-entry.

The LOFTID, a project of NASA’s Space Technology Mission Directorate, falls under its Technology Demonstration Missions program. In partnership with United Launch Alliance (ULA), the current LOFTID launch is being overseen out of Langley Research Center in Hampton, Virginia.

US Congressman Says Revealing UFO Technology Is a Threat to Energy Sector: It Can Disrupt World Economy

A thought-provoking interview has recently been conducted between Project Unity host Jay Anderson and the U.S. Congressman Andy Ogles. The discussion focused on the implications of complete UAP (Unidentified Aerial Phenomena) disclosure. Anderson asked serious questions to Rep. Ogles about UFOs, revealing that the release of extraterrestrial technology could potentially disrupt the world economy and energy sector.

Rep. Andy Ogles spoke about the difficulty in gathering information due to the compartmentalization of special access projects, emphasizing the need for a methodical and persistent approach to uncover the truth. In the interview, he expressed his concern about UAPs operating in both military and commercial airspace, raising questions about the potential national security threats. He said, “I’m not going to assume I know what it may or may not be. What I do know is there’s a national security issue here.”

He considers various possibilities, including the involvement of experimental aircraft, joint ventures, or foreign adversaries. He emphasizes the importance of avoiding predetermined conclusions and encourages an open-minded investigation to determine the true nature of the UAP phenomenon.

When asked about his personal understanding of UAPs, Rep. Ogles talks about the hope that it might be advanced technology possessed by the United States. He says, “My hope would be… some new technology that we possess… puts us that next generation above our adversaries.” However, he acknowledges the mysterious aspects of UAPs, saying they seem to “defy physics.”

Rep. Ogles then considers the energy implications of the advanced propulsion technology displayed by UAPs. He wonders about the amount of energy needed for such rapid movements and how it could impact the energy sector.

He says, “That being said, these UAPs seem to defy physics. They seem to have some sort of propulsion technology that’s unknown to man as we understand it. So, what does that do to the energy sector? If there’s a new way of thinking about the amount of energy it takes to take a craft that’s hovering and suddenly it’s going Mach one in a matter of seconds – the human body can’t sustain that as we understand it, right? So that craft would have to have next-level technology to protect tissue, if you will, or it’s an unmanned type of craft. Again, there are just a lot of questions that have to be probed. But, if there is this propulsion technology out there and this energy capability out there, not only are we in a renaissance when it comes to aircraft, but we’re in a renaissance in terms of propulsion and energy production consumption. So, again, huge implications across the economic scale, both domestically and internationally.”

He mentions his inquiries in committee about the DOE (Department of Energy), suggesting it could be an ideal place to house top-secret technologies. He says, “If you’re going to house a top-secret Next Level technology, what better place to have it and house it than… nuclear facilities.”

“Everybody knows about Area 51. It’s a testing area… You’ve got this super top-secret, super secure facility that, again, would be ideal to have and to house some new technology, emerging technology that we want to fully master for ourselves and quite frankly control. Because again, as you look at that next generation of warfare, it’s not just tanks and planes. It’s drones. It’s unmanned aircraft. It’s economic. There’s a lot that’s about to happen as we go forward as a superpower and our competitive edge on the global stage.”

Later in the interview, Jay Anderson brings up Congressman Burchett’s positive impression of David Grusch’s testimony during classified briefings. Rep. Ogles says that credible sources have vouched for Grusch’s reliability. He suggests believing what Grusch said, thinking about it carefully, and not trying to say it is wrong without some good proof. Ogles says it is important to keep an open mind, focus on getting answers, and not to try finding faults without good reasons.

Rep. Ogles explains that it does not require unanimous congressional support but rather the speaker’s will to initiate action. He emphasizes the bipartisan interest in addressing the issue and expresses the need for a select committee to ensure transparency and accountability in the investigation. He, along with Congressman Burchett, acknowledges the likelihood of a multi-decade cover-up or compartmentalization due to the secretive nature of special access programs (SAPs) and classified information related to national security.

When asked about evidence suggesting reverse engineering or more exotic propositions, Rep. Ogles mentions the classification of such information and the need for careful consideration. He discusses questions about the origin of technology, whether it is our own creation or recovered from elsewhere, and the potential for reverse engineering.

• US Congressmen Claim Bible Has ‘Pretty Clear’ Evidence of UFOs: Vatican Knows Aliens Are Here

Stephen Bassett, the only registered lobbyist of Washington and founder of Paradigm Research Group, shares the same UFO disclosure concerns that will pose serious implications for the world’s economy.

The PRG researchers claim they have known the reasons why the US authorities were hiding information about UFOs. According to them, disclosing UFO data would lead to the collapse of the entire world economy. Bassett added that all so-called “flying saucers” do not use oil, gasoline, gas, or coal. “They have a different energy system. Without a doubt, a much more complex and deep system based on anti-gravity,” he said.

“Some programs have been removed from the jurisdiction of the White House and Congress and are working somewhere very, very deep, in a ‘hidden mode,'” the researcher emphasized. “I assure you, when the head of state finally officially admits this fact and presents evidence, people will start to worry and want to know more.” But even if the economy stops developing in the current way, it will have new opportunities, Bassett believes.

During an interview with uInterview, he said that UFOs are not unidentified flying objects, as the acronym suggests, but rather alternative energy and propulsion devices. The technology behind UFOs was heavily studied by a team headed by Dr. Vannevar Bush in the 1940s, 1950s, and 1960s, and by 1954, they had developed what is known as “gravity control” and “zero-point energy.”

[Editor’s note] In January 2015, former NASA astronaut Edgar Mitchell sent an email to Podesta, asking him to have an urgent meeting to discuss Disclosure and Zero Point Energy (ZPE). He was concerned about the peace in space. Mitchell wrote: “My Catholic colleague Terri Mansfield will be there too, to bring us up to date on the Vatican’s awareness of ETI. Another colleague is working on a new Space Treaty, citing involvement with Russia and China. However, with Russia’s extreme interference in Ukraine, I believe we must pursue another route for peace in space and ZPE on Earth.” (Click here to read the full article)

However, Dr. Greer stated that the secrecy surrounding this technology went off the rails and became deeply entrenched in compartmented intelligence operations, even causing President Eisenhower to become frustrated with being denied information on the projects.

“The problem became to be, and this is what President Eisenhower warned us about, the secrecy became so enmeshed and compartmented in intelligence operations, that even he as president lost control over it,” Dr. Greer said.

He further stated: “One of our military witnesses, he was a young man working at the White House – which I’m looking at from my place here in Washington, he told us, Mr. Lubkin, who is an attorney, said that Eisenhower was very frustrated that he was being denied information on the projects controlling this issue. So the secrecy went off the rails into these unacknowledged special access projects.”

The disclosure of UFOs would mean the end of oil, gas, coal, and public utilities, as the technology would completely transform the world. Those with trillions of dollars invested in these industries would not be enthused about this possibility. This is the reason for the secrecy, and it has been maintained for 70 years, according to Dr. Greer.

The discovery raises several intriguing questions about Mars and its history, as well as what environmental factors could have led to the formation of the crystals.

A Chance Discovery

Since October 2023, Curiosity has been scouring the Gediz Vallis channel on Mount Sharp, an area where scientists believe ancient lava flows occurred in the planet’s early history. The Martian rover has concentrated its explorations in the area, given the region’s promising potential for having once been home to microbial life or even the possibility that it may still be a present-day refuge for such simple organisms.

The discovery of the colorful mineral was made by chance, as Curiosity cracked open a rock while driving over it. To the Curiosity team’s surprise, the yellow interior of the stone revealed what is likely to be pure sulfur, whereas the sulfates that are normally encountered in the area are salts comprised of combinations of sulfur and other minerals.

Unveiling Mount Sharp’s Mysteries

Since 2014, NASA’s Curiosity rover has made its ascent of Mount Sharp, where its explorations of the Gediz Vallis channel have revealed a portion of the landscape once shaped by ancient water flows on the planet. Curiosity’s present mission is to investigate whether this ancient channel and its surrounding terrain could have supported microbial life, particularly at a time when water was more abundant on Mars.

“This was not a quiet period on Mars,” according to Becky Williams, a scientist at the Planetary Science Institute and deputy principal investigator of Curiosity’s Mast Camera. “There was an exciting amount of activity here.

“We’re looking at multiple flows down the channel, including energetic floods and boulder-rich flows,” Williams said.

Going forward, the Curiosity team hopes to conduct drilling on larger rocks in the area to determine if they may also contain sulfur crystals. Presently, the relationship between elemental sulfur and other sulfur-based minerals in the area remains unclear to scientists studying the Martian environment.

“Finding a field of stones made of pure sulfur is like finding an oasis in the desert,” said Ashwin Vasavada, Curiosity’s project scientist at NASA’s Jet Propulsion Laboratory.

“It shouldn’t be there, so now we have to explain it,” Vasavada said in a statement.

“Discovering strange and unexpected things is what makes planetary exploration so exciting.”

With the help of advanced capabilities that include the use of undersea robots, scientists are now assembling a clearer picture than ever before of the dynamics of melt occurring at the ice base of West Antarctica’s Dotson Ice Shelf.

Basal Melt Processes and Ice Shelf Stability

Melt rates beneath Antarctic ice shelves often show remarkable variability. One factor that influences this process, one that scientists have focused on in recent years, is how warmer salt water interacts with the ice along the base of the continent’s ice sheets.

One significant mechanism that contributes to this mixing of warm water into the ice-ocean boundary is turbulence resulting from shear-driven mixing. Another is vertical convection, which includes a process known as double-diffusive convection, although these generally produce lower melt rates. However, when combined, these processes have now been revealed to produce uniquely shaped features on the base of the ice, which include the formation of what are sometimes very large basal channels and terraces.

Due to varying oceanic conditions, ice can sometimes melt at different rates even along the same ice shelf. This appears to be caused by factors that include not only ocean temperature but also the speed of ocean water’s movement, both of which contribute to diverse formations of natural features along the base of Antarctica’s ice.

According to new findings detailed in a study published in Science Advances, researchers have successfully mapped these changes with the help of an autonomous underwater vehicle (AUV), revealing remarkable and never-before-seen details about the processes that are driving accelerated melt along the continent’s ice shelves.

Overall, the research team found that the basal topography of the Dotson Ice Shelf varies significantly between its eastern and western portions. While the ice is thicker and appears to be melting more slowly to the east, on the opposite end, the opposite is the case, with noticeably thinner ice indicating higher melt rates.

In their study, the research team links these variances in ice melt rates to the presence of what is called modified Circumpolar Deep Water (mCDW), which refers to Pacific and Indian Ocean water mixing with other nearby water masses and interacting with the ice base. Faster-moving currents in the western region revealed smooth features on the base of the ice, accompanied by higher melt rates.

In contrast, the central and eastern regions of the ice sheet bore evidence of terraced features, which the research team attributes to warm water intrusions that occur closer to these areas.

Ultimately, the presence of remnant winter water and mCDW mixtures was revealed to produce streaks of temperature and meltwater that significantly influence overall melt rates. The team’s findings through AUV observations help to reveal how future missions may be able to reveal further details about the Antarctic ice base and how shear-driven turbulence and the presence of warm water accelerate melting in the western outflow region.

“This new wealth of processes, all active under a single ice shelf, must be considered to accurately predict future Antarctic ice shelf melt,” the team writes in their recent study. Going forward, ongoing mapping and study of the ice shelf will be crucial in order to refine existing models, in addition to improving our understanding of ice-ocean interactions and their relationship to rising sea levels in the years ahead.

The team’s new study, “Swirls and scoops: Ice base melt revealed by multibeam imagery of an Antarctic ice shelf,” by Anna Wahlin, et al., appeared in Science Advances on July 31, 2024.

The Day After Tomorrow? A climate disaster could occur at ANY time in the next 6,000 years, scientists warn

• Researchers say it's almost impossible to predict timing of climate tipping points
• They warn catastrophe could strike at any time in the next 6,000 years

By Xantha Leatham Deputy Science Editor

It's the film that left us all wary of disastrous and abrupt climate change.

But The Day After Tomorrow is probably not when we're going to experience apocalyptic weather events, according to a study.

Researchers argue that it's almost impossible to predict the timing of climate tipping points – and that catastrophe could strike at any time in the next 6,000 years.

A team from the Technical University of Munich and the Potsdam Institute for Climate Impact Research provided the Atlantic Meridional Overturning Circulation (AMOC) as an example.

This system circulates water from north to south and back in a long cycle within the Atlantic Ocean, carrying warm water from the tropics northwards.

It's the film that left us all wary of disastrous and abrupt climate change. But The Day After Tomorrow is probably not when we're going to experience apocalyptic weather events, according to a study

• The real-life Day After Tomorrow? The Gulf Stream is weakening thanks to climate change 

Climate models suggest the AMOC will weaken over the 21st century due to increases in greenhouse gases and melting ice.

If the system collapsed the Northern Hemisphere would get colder, causing temperatures in Europe to drop dramatically.

Wet seasons in the Amazon rainforest would be reversed to dry seasons, and in coastal cities the sea would rise even faster.

Previous predictions from historical data suggest a collapse could occur between 2025 and 2095.

However, the new study revealed that uncertainties are so large that these predictions are not reliable.

Using different data sets and analysis, tipping times for the AMOC ranged from 2050 to 8065 – a 6,000-year window which isn't particularly useful, the researchers said.

Writing in the journal Science Advances they said the timing of other climate tipping points – such as the melting of the polar ice sheets or the collapse of tropical rainforests – are also too uncertain.

This is because there is too much still unknown about the underlying physical mechanisms of climate change, a lack of direct observations of the climate system, and incomplete history data, they explained.

Lead author Maya Ben-Yami said: 'Our research is both a wake-up call and a cautionary tale.

Climate models suggest the AMOC will weaken over the 21st century due to increases in greenhouse gases and melting ice. If the system collapsed the Northern Hemisphere would get colder, causing temperatures in Europe to drop dramatically 

'There are things we still can't predict, and we need to invest in better data and a more in-depth understanding of the systems in question.

'The stakes are too high to rely on shaky predictions.'

While the study shows we cannot reliably predict tipping events, the possibility of such events cannot be ruled out either, the team said.

They also stressed that statistical methods are still very good at telling us which parts of the climate have become more unstable.

'We still need to do everything we can to reduce our impact on the climate, first and foremost by cutting greenhouse gas emissions,' co-author Niklas Boers said.

'Even if we can't predict tipping times, the probability for key Earth system components to tip still increases with every tenth of a degree of warming.'

Flakes of Natural Graphene Found in Lunar Soil Samples

 by Natali Anderson

In lunar regolith samples collected by China’s Chang’e-5 probe, planetary scientists have identified few-layer graphene formed together with complex minerals. The finding provides new insights into the origin of the Moon, supporting the hypothesis of a carbon-containing Moon.

Structural and compositional characterization of few-layer graphene in the Chang’e-5 lunar soil sample.

“Graphene has revolutionized the research of condensed matter physics and materials science with its novel physical phenomena and extraordinary properties,” said Jilin University Professor Wei Zhang and colleagues.

“It plays an increasingly important role in extensive areas including planetary and space science.”

“It is estimated that around 1.9% of total interstellar carbon is in the form of graphene and protosolar graphene has been identified in carbonaceous chondrite meteorites.”

The researchers analyzed an olive-shaped sample of lunar soil, about 2.9 mm by 1.6 mm, collected by the Chang’e 5 mission in 2020.

Using a special spectrometer, they found an iron compound that is closely related to the formation of graphene in a carbon-rich section of the sample.

They then used advanced microscopic and mapping technologies to confirm that the carbon content in the sample comprised ‘flakes’ that have two to seven layers of graphene.

The scientists proposed that the few-layer graphene may have formed in volcanic activity in the early stages of the Moon’s existence, and been catalyzed by solar winds that can stir up lunar soil and iron-containing minerals that helped transform the carbon atoms’ structure.

Meteorite impacts, which create high-temperature and high-pressure environments, may also have led to the formation of graphene.

“This is the first study to verify the presence of natural few-layer graphene in lunar soil samples by examining its microstructure and composition,” the authors said.

“Our finding provides new insights into the origin of the Moon, supporting the hypothesis of a carbon-containing Moon.”

“Moreover, the exotic properties of graphene are highly structurally and environmentally dependent.”

“Further in-depth property investigation of natural graphene would provide more information on the geologic evolution of the Moon.”

“In turn, the mineral-catalysed formation of natural graphene sheds light on the development of low-cost scalable synthesis techniques for high-quality graphene.”

“Therefore, a new lunar exploration program may be promoted and some forthcoming breakthroughs can be expected.”

Chinese researchers have discovered a form of carbon in lunar soil samples collected in 2020 which could overturn the theory that the moon was formed by a cosmic collision between Earth and a smaller planet.

Study: Lunar soil has the right stuff for “extraterrestrial photosynthesis”

It could pave a way for plants, fuel, and so much more.

by Doris Elín Urrutia

 

Rainer Fuhrmann / EyeEm/EyeEm/Getty Images

What’s new — The new study proposes “extraterrestrial photosynthesis,” a process by which humans in space can draw on just two simple, out-of-this-world ingredients — lunar soil and sunlight — to produce fuel and recycle carbon dioxide back into breathable oxygen on long-duration crewed missions to the Moon and Mars.

One major talking point for space agencies with their eyes to the skies: How do you power a trip far from Earth? The longest crewed lunar mission to date — NASA’s Apollo 15 flight in 1971 — lasted 12 days. They maintained themselves on the supplies they brought along, which had the heaviest payload in a lunar orbit at about 107,000 pounds.

Digging into the details — The study looks at ways to replenish water, oxygen, and fuel by using human byproducts, solar radiation, and local lunar soil called regolith. If this is successfully achievable, space agencies can save on cargo weight and vehicle space for crewed missions lasting weeks or even months.

Their preliminary findings inspired them to propose a model for how a self-sustaining Moon outpost could work.

The team analyzed the Chang’e-5, or “CE-5,” regolith samples to see what chemicals they contained and then investigated how well these components could catalyze carbon dioxide into oxygen. Exhaled breath might be used for potable water, or turned into hydrogen or methane for fuel.

Their experiments yielded some positive results. They saw bubbles of hydrogen and oxygen gas, for example. The paper reports that compounds in lunar regolith catalyzed a reaction during a photovoltaic-driven water electrolytic (PV-EC) test, which takes light and water and turns the liquid into those two gases. On the Moon, the water used here would come from lunar ice and human breath that would have previously gone through a dehydrating process. The astronauts would use the water for drinking.

What’s next — A lot more needs to be done before the research is Moon-ready. The researchers wrote that “the current catalytic performance from the CE-5 lunar sample cannot fully satisfy the requirement of extraterrestrial survival,” adding that their findings weren’t on par with the efficiency of existing catalyst systems on Earth.

They wrote that researching the compounds on the Moon more thoroughly could lead to more success.

Green Light in Ibiza Skies: UFO or Illusion?

The Incident

The incident occurred on a clear day near the coastline of Ibiza, a popular tourist destination known for its stunning beaches and vibrant nightlife. A group of tourists, enjoying the scenic beauty near a cliff, inadvertently became witnesses to an unusual phenomenon. The video, recorded by one of the tourists, begins with a serene view of the landscape, capturing the natural beauty of the area.

Suddenly, the tranquility is interrupted by a girl running and pointing towards the sky, drawing the attention of the others. The camera follows her gesture, panning to reveal a bright, clear sky with the moon prominently visible. Beside the moon, an unidentified object appears, hovering momentarily before it disappears within seconds. The object’s sudden vanishing act leaves the onlookers stunned and puzzled.

Public Reaction

The video quickly gained traction on social media, with users from around the world sharing and commenting on the mysterious sighting. UFO enthusiasts were particularly excited, viewing the footage as potential evidence of extraterrestrial activity. Skeptics, on the other hand, offered various explanations ranging from natural atmospheric phenomena to sophisticated drones or even a hoax.

Regardless of one’s stance on the existence of UFOs, the video has undeniably sparked curiosity and debate. Many people are fascinated by the possibility of encountering something beyond the realm of known science, while others enjoy the mystery and intrigue that such sightings bring.

Expert Opinions

To gain a deeper understanding of the sighting, several experts were consulted. Dr. Laura Mendes, an astronomer and UFO researcher, analyzed the footage and provided her insights.

“The video is intriguing, and while it does show an unidentified object, it’s important to approach such sightings with a scientific mindset. There are many plausible explanations, including atmospheric distortions, reflections, or man-made objects. Without more data, it’s difficult to draw any definitive conclusions,” Dr. Mendes stated.

Aviation expert Carlos Rodriguez also weighed in on the sighting. “Given the proximity to a tourist area, it’s possible that what was seen could be a drone or another type of aircraft. However, the rapid disappearance is unusual and warrants further investigation,” he remarked.

Historical Context of UFO Sightings

UFO sightings have been reported for centuries, with varying levels of credibility and detail. From ancient texts describing celestial events to modern-day videos captured on smartphones, the phenomenon has persisted through time. One of the most famous incidents is the Roswell incident of 1947, where an alleged UFO crash in New Mexico spurred widespread speculation and conspiracy theories.

In recent years, the U.S. government has declassified numerous reports and videos of unidentified aerial phenomena (UAP), reigniting interest in the topic. These disclosures have lent some credibility to the notion that there are aerial objects that defy conventional explanations.

The Science Behind UFOs

While the idea of extraterrestrial visitors is captivating, scientists urge caution and critical thinking. Most UFO sightings can be attributed to natural phenomena or human activities. For instance, weather balloons, experimental aircraft, and atmospheric conditions can create optical illusions that mislead observers.

The scientific method relies on reproducibility and evidence. For a UFO sighting to be considered credible, it must be corroborated by multiple witnesses, radar data, and other forms of empirical evidence. In the case of the Ibiza sighting, while the video is compelling, more information would be needed to reach a conclusive explanation.

The Cultural Impact of UFO Sightings

UFO sightings often capture the public’s imagination and inspire various forms of media, including movies, books, and television shows. The idea of encountering alien life forms has become a staple of science fiction, reflecting humanity’s curiosity and desire to explore the unknown.

Movies like "Close Encounters of the Third Kind" and "Independence Day" have popularized the concept of UFOs and alien encounters, blending entertainment with speculative science. These cultural artifacts shape our perception of UFO sightings, often blurring the lines between fiction and reality.

Personal Accounts and Eyewitness Testimonies

Eyewitness testimonies play a crucial role in the study of UFO sightings. Personal accounts, like the one from Ibiza, provide valuable insights into how these phenomena are experienced and perceived by individuals. However, eyewitness accounts are also subject to cognitive biases and memory distortions, which can affect the accuracy of the observations.

In the Ibiza case, the tourists’ reactions and the immediate recording of the event add a layer of authenticity to the sighting. Their spontaneous responses and genuine astonishment suggest that they truly witnessed something unexpected.

The Role of Technology in UFO Sightings

Advancements in technology have significantly impacted the documentation and analysis of UFO sightings. High-resolution cameras, drones, and satellite imagery provide new tools for capturing and investigating aerial phenomena. These technologies can help distinguish between known objects and genuinely unidentified ones.

The Ibiza video, recorded on a smartphone, benefits from modern technology, offering clear footage that can be analyzed frame by frame. This level of detail was not available in earlier UFO sightings, making contemporary reports more credible and easier to scrutinize.

Government Involvement and Disclosure

Governments worldwide have historically shown interest in UFO sightings, often conducting secret investigations. The U.S. government’s recent release of UAP reports has highlighted the importance of transparency and scientific inquiry in addressing these phenomena.

In Spain, the government has not released any official statements regarding the Ibiza sighting. However, the increasing public interest in UFOs may prompt authorities to take a more proactive role in investigating and disclosing information about such incidents.

Conclusion

The UFO sighting in Ibiza has captured the imagination of people around the world, reigniting debates about the existence of extraterrestrial life and the nature of unidentified flying objects. While the video offers a tantalizing glimpse of something unexplained, it also underscores the need for rigorous scientific investigation and critical thinking.

As technology continues to advance and more sightings are documented, the mystery of UFOs may eventually be unraveled. Until then, incidents like the one in Ibiza will continue to intrigue and inspire, reminding us of the vastness and wonder of the universe.

Whether you are a skeptic or a believer, the sighting serves as a reminder that there is still much to explore and discover in our world and beyond. The quest for understanding UFOs is not just about finding answers but also about embracing the unknown and celebrating the human spirit of curiosity and exploration.

Cryptoterrestrials: Are Aliens Already Living Among Us?

The concept of extraterrestrial life has long captivated the human imagination, often depicted as beings visiting Earth from distant galaxies. However, a compelling hypothesis suggests an alternative possibility: aliens might already be living among us, hiding in plain sight as “cryptoterrestrials.” This theory challenges traditional views of alien life and opens up intriguing discussions about the nature of extraterrestrial existence on Earth.

Understanding the Cryptoterrestrials Hypothesis

The cryptoterrestrials hypothesis proposes that extraterrestrials are not just visiting Earth but have been residing here, possibly for millennia. Unlike the typical depiction of aliens arriving in spaceships from far-off planets, cryptoterrestrials are thought to be integrated into human society, cleverly disguised to avoid detection. This idea shifts the focus from outer space exploration to a more introspective examination of life on Earth.

Four Categories of Cryptoterrestrials

The hypothesis can be divided into four distinct categories, each presenting a unique perspective on how aliens might be living among us:

1. Ancient Super Civilization: This theory suggests that an advanced civilization once thrived on Earth but was destroyed by a catastrophic event, such as a flood. The survivors of this civilization, possibly connected to legends like Atlantis, might still be present today, blending into human society.
2. Animal-Like Alien Civilization: Another possibility is that a complex civilization of aliens exists, resembling more animal-like beings rather than humanoid forms. These creatures might have developed unique ways to coexist with humans, perhaps living in remote or hidden locations.
3. Hidden Underground Aliens: Some theorists propose that aliens are hiding underground, utilizing Earth’s vast subterranean environments to remain concealed. This notion aligns with various myths and legends of underground worlds inhabited by mysterious beings.
4. Magical or Mythical Beings: The final category encompasses the idea that aliens could be perceived as mythical creatures, such as sprites, fairies, or goblins. These beings might possess abilities that enable them to exist undetected, contributing to folklore and mythical narratives.

Speculation and Skepticism

The cryptoterrestrials hypothesis, while intriguing, is primarily speculative. It seeks to expand the boundaries of thought and academic discussion, challenging established notions about extraterrestrial life. However, it’s important to note that proponents of this hypothesis acknowledge the lack of concrete evidence supporting the idea of aliens walking among us. The hypothesis is intended to provoke thought and encourage exploration of alternative possibilities rather than make definitive claims.

The Role of Media and Public Perception

Media plays a significant role in shaping public perception of the cryptoterrestrials hypothesis. Sensationalist headlines and exaggerated claims can often distort the original intentions of speculative discussions. While some media outlets may present the idea humorously or dismissively, it is crucial to approach such topics with an open mind and a critical eye.

A Historical Perspective

Throughout history, many revolutionary scientific ideas have initially been met with skepticism and ridicule. The notion of a round Earth, once considered absurd, eventually became a widely accepted fact. Similarly, the cryptoterrestrials hypothesis challenges us to reconsider our understanding of life on Earth and the potential for hidden civilizations.

Conspiracy Theories and Cultural Influences

The cryptoterrestrials hypothesis intersects with various conspiracy theories and cultural beliefs about non-human entities living among us. Concepts like “lizard people” or “skinwalkers” have circulated for decades, often rooted in folklore and mythology. The hypothesis serves as a framework to explore these longstanding ideas and examine their plausibility in a modern context.

The Possibility of Alien Integration

While the cryptoterrestrials hypothesis remains speculative, it raises thought-provoking questions about the potential motivations and methods of extraterrestrial life integrating into human society. If aliens are indeed living among us, what could they gain from such integration? Would their presence have an impact on human culture, technology, or evolution?

The Age of the Galaxy and Earth’s History

Considering the vast age of the galaxy, estimated to be around 13 billion years, and Earth’s 4.5 billion-year history, there is ample time for the development and evolution of intelligent life forms. If cryptoterrestrials do exist, they might have arrived on Earth long before humans, potentially influencing the course of human history in ways we have yet to understand.

The cryptoterrestrials hypothesis invites us to expand our perspective on extraterrestrial life, challenging the conventional narrative of aliens as distant visitors. While evidence supporting the existence of cryptoterrestrials is currently lacking, the hypothesis encourages curiosity and exploration of alternative explanations for unexplained phenomena. As scientific understanding evolves, the possibility of discovering hidden civilizations or new forms of life continues to inspire both intrigue and skepticism. Ultimately, the cryptoterrestrials hypothesis serves as a reminder of the boundless mysteries that the universe, and perhaps even our own planet, still holds.

20 Years Later, MESSENGER Is Still Giving Us Strange Hidden Gems

A recent study looking decades-old data suggests Mercury may have a 10-mile-thick layer of diamond deep in its interior.

by Kiona Smith

 

NASA

Yongjiang Xu, of the Center for High Pressure Science and Technology Advanced Research in Beijing, and his colleagues published their work in the journal Nature Communications.

Diamonds In The Rough

Like most rocky planets, Mercury was once a seething, churning ball of magma. Over time, that magma cooled and solidified, and in the process, it settled into layers — giving the planet a dense inner core, a slightly lighter and mostly fluid mantle, and a light, rocky outer crust. To simulate that process, Xu and his colleagues made digital models using data from MESSENGER that offered clues about Mercury's inner structure. They also squashed a lot of carbon samples in the lab to see how the material behaved under tremendous heat and pressure.

According to Xu and his colleagues’ simulations, there should be a layer of diamond lying atop Mercury's core and just beneath its mantle — and it could be between 9 and 11 miles thick. The diamond would have crystallized out of an ocean of carbon-rich magma that once covered Mercury billions of years ago.

Meanwhile, on the surface, carbon crystallized into a different (and much less sparkly) form called graphite. Graphite and diamond are both pure carbon, but the atoms are arranged in different crystal structures, which gives the two materials very different properties. At the surface, where pressures and temperatures were much lower, the carbon formed dark, soft graphite. Deep below, the intense pressure beneath Mercury's mantle pressed carbon into diamond — if Xu and his colleagues are right.

Don’t Shoot The Messenger

The finding is just the latest scientific gem MESSENGER has laid at our feet since its launch 20 years ago. It took four years just to reach Mercury in 2008, and then the spacecraft had to make a carefully-planned series of flybys to slow down enough to enter Mercury's orbit without also accidentally getting pulled into the Sun. (Trying to maneuver a spacecraft that close to the Sun's gravitational influence is a challenge.) MESSENGER settled into Mercury's orbit in 2011.

During its four years in orbit around Mercury, MESSENGER revealed some surprising things about our Solar System's innermost planet. One of those is the graphite that dusts its surface, which gives the planet's surface its dark, patchy appearance — and gave Xu and his colleagues the idea for their recent simulations.

MESSENGER also revealed that Mercury has tectonic quakes, similar to the quakes that happen on Earth and Mars, and that the already-small planet is actually shrinking a little bit every year. The mission found evidence of frozen water deep in the permanent shadows of some of Mercury’s polar craters. And there's even a hint that some organic chemistry, and maybe even very simple cells, once could have eked out an existence beneath the planet's surface.

Xu and his colleagues’ simulations may help explain another of MESSENGER's most important discoveries: Mercury's surprisingly strong magnetic field.

For such a small planet, Mercury boasts a disproportionately powerful magnetic field. If Xu and his colleagues are right, the layer of diamond lying beneath the mantle could be changing how heat flows from the core to the mantle (because diamond transfers heat very efficiently). That, in turn, could be changing how convection, currents driven by hot liquid rising and cool liquid sinking, happens in the molten outer layers of Mercury's core. And since all that flowing molten metal is part of what generates the magnetic field, the diamond layer could be a big part of the explanation.

The MESSENGER mission came to a dramatic end on April 30, 2015, when the spacecraft smashed into Mercury's surface at more than 8,000 miles per hour. Because MESSENGER was on the far side of the planet at the time, its human team back on Earth didn't witness its final moments; they heard only the silence of the dead spacecraft failing to resume radio contact a few moments later.

MESSENGER set the foundation for the European Space Agency's BepiColombo mission, and it may also shed light on the interiors of other rocky planets.

"The processes that led to the formation of a diamond layer on Mercury might also have occurred on other planets, potentially leaving similar signatures," says Yanhao Lin, also of the Center for High Pressure Science and Technology Advanced Research in Beijing and a coauthor of the recent study, in a recent statement. The riches of the Universe seem to only grow with time.
