This recent video was taken at a beach in California. The eyewitnesses saw several diamond black objects in the sky for about 15 minutes and they moved only a little bit, but just disappeared soon after. In the video you can see several people turn and look upward at the black UFOs, but then go about their business enjoying the beach. Why? Because its the beach, and thats what people love to do, including me. Aliens in California...like thats news to any of us from there.

Abducted by Aliens: UFO Encounters of the 4th Kind

For centuries, people have reported being taken by alien entities against their will. These experiences, known as the fourth kind encounters, involve complex physical and psychological procedures that leave many victims traumatized. But what if our government is aware of these abductions and is powerless to prevent them?

So what do we really know about the truth behind these abductions? While the full agenda of the beings responsible remains a mystery, there is no denying that these encounters have left a lasting impact on those who have experienced them.

One thing is for sure: as we continue to uncover more information about these phenomena, we become better prepared for the day when we will have full disclosure that we are not alone in the universe. Whether or not we are being taken by beings from outer space or another dimension, the truth is out there waiting to be uncovered.

Bringing Mars Rock Samples Back to Earth

November 17, 2022

NASA and the European Space Agency are developing plans for one of the most ambitious campaigns ever attempted in space: bringing the first samples of Mars material safely back to Earth for detailed study. The diverse set of scientifically curated samples now being collected by NASA’s Mars Perseverance rover could help scientists answer the question of whether ancient life ever arose on the Red Planet.

Bringing samples of Mars to Earth for future study would happen in several steps with multiple spacecraft, and in some ways, in a synchronized manner. This short animation features key moments of the Mars Sample Return campaign: from landing on Mars and securing the sample tubes to launching them off the surface and ferrying them back to Earth.

Animation is contributed by NASA’s Jet Propulsion Laboratory, the European Space Agency, Goddard Space Flight Center, and Marshall Space Flight Center.

With all the unknown small objects flying around, I thought I woud share some cases with you. So, let's get started. Here's the first case. April 13, 1964. At around 8:40 p.m. on the night in question, bus-driver Bob Fall was driving alongside the River Lea in the town of Walthamstow, England when his attention was drawn to a fast-moving aerial object that barely missed his bus as it plunged into the depths of the river. He said: “I just glanced into the sky and saw something coming towards me very, very fast. It flew straight across the road and, had I been a few yards further forward, it would have hit the top deck of the bus. At first I thought the back windows of the bus had come in and, as I turned around, I saw all the passengers looking out towards the river. There was a big splash in the water. I stopped as soon as I could to report it. The thing was at least nine feet long, cigar-shaped and silver,” he insisted. “If it had been a bird or birds I [would] have seen the wings. Besides, it was going too fast.” As a result of the media publicity afforded this event, a British UFO investigator, Ronald Caswell of Harlow, Essex, looked into the case and uncovered a wealth of data that had been almost completely overlooked by his contemporaries.

His notes state:            

“I have a piece of one of the telephone wires broken by the object. A newspaper shows great coils of it on the towpath. The police spokesman’s suggestion that a duck, or even four ducks, could have broken those wires is ridiculous. Neither could a swan. The length of the wire across the river would have moved away at the pressure of a plummeting bird, and the bird would certainly have been badly injured, if not killed.” Notably, Caswell also said that he learned “…when it was late enough for the general public to have cleared off, heavy lifting equipment was brought in and a find was made in the early hours of the morning.” What that “find” was, has never been disclosed. Now, to another case of the "object" type. 

January 4, 1965: “We have drawn a blank”: In the early part of 1996, the British Ministry of Defense (MoD) declassified under the terms of the Government’s “Thirty Year Ruling” (legislation designed to ensure that all documents, regardless of classification, were withheld from public scrutiny for a minimum of 30 years) a file that detailed a variety of UFO reports that the MoD received during 1965. Contained within the file was an 11-page report concerning an unidentified object that was seen to come down in the vicinity of March, Cambridgeshire, England on January 5, 1965. A man named Max Beran, one of those who witnessed the descent of the object, quickly wrote to the Meteorological Office Unit (MOU) at Huntington Road, Cambridge. Beran stated: “Whilst in the sunlight it remained visible, giving the appearance of a curved object. Perhaps a parachute, but I would have thought too fast for that. Before falling too low to be visible in the low sun it appeared to be falling to a point perhaps a mile or two Southeast of the town center from where I was watching. What could the falling object have been?”

The Senior Meteorological Officer at Cambridge immediately contacted his headquarters at Braknell, Berkshire, regarding Beran’s letter. Recognizing that this was a matter for the Ministry of Defense, Braknell prepared a one-page memorandum for the MoD outlining the facts. The MoD quickly swung into action. According to a one-page handwritten note contained within the file, the police at March had been directed by the MoD to look into the matter. “[The police] sent a car out to look for the object in the vicinity of the ‘Sixteen Root Drain’ but without success,” stated the note. The MoD also put numerous questions to a host of other official departments as it sought to locate and identify the UFO, including the Royal Navy, the Ministry of Aviation, and various civil aviation bodies. Whatever the object was, the MoD claimed, it was not a piece of military hardware. “Things which may on occasion fall from aircraft include external fuel tanks, drag-chutes, cockpit canopies, access panels on doors, and sometimes accumulations of ice,” the MoD informed Max Beran. “We have looked carefully into all these possibilities so far as our own aircraft are concerned, but have drawn a blank.”

Number 3: January 6, 1995: Collision course!“A close encounter between a British Airways jet with 60 passengers on board and an illuminated, triangular-shaped, unidentified flying object at 13,000 feet above the Pennines is under formal investigation by the Civil Aviation Authority,” stated the Times newspaper on February 2, 1995.The incident had actually taken place on January 6, 1995, as Captain Roger Wills and co-pilot Mark Stuart began their descent towards Manchester Airport, England, in a Boeing 737 twin jet. Seventeen minutes before touchdown, all was normal until a mysterious object flashed past the right-hand side of the aircraft at a distance described as being “very close.” So close, that the crew actually “ducked down” in their seats as the object sped past them. An immediate check with air traffic control at Ringway revealed that nothing had been picked up on radar, save for the 737 itself.

Anticipating ridicule, the crew of flight BA 5601 did not report the incident to their colleagues; however, British Airways management was ultimately advised of what had occurred. In line with set procedures, a full report, complete with sketches of the UFO, was sent to the Joint Air Miss Working Group, a part of the Civil Aviation Authority. A CAA spokesperson said that any suggestion that the object had been a UFO was “purely speculative,” adding that the investigation could last up to six months. The spokesperson told the press: “A very small proportion of near-miss situations involving untraced aircraft remain unresolved.” This was one of those “unresolved” ones.

February 5, 1986: An unexplained encounter in the skies: A brief UK Ministry of Defense document reveals the salient data on a UFO encounter involving a highly respectable source, an airline pilot who sighted a UFO in the airspace of Ireland. The report states: “5 Feb 86 5427N 0530W – Bright light passed upwards in front of A/C. A/C was crossing east coast of Ireland on descent. Light travelled towards A/C from a 2.30 position range approx. 11/2 miles and passed 1000 feet above travelling right to left 1 mile ahead. Burst of green light observed at peak of its ballistic flight. A/C ht [height] 1450 ft. CAA closure – possibly flare fired at about time of OCC by Aldergrove. Pilot considered this unlikely but no other explanation has emerged.”

June 12, 1982: A 500-foot-long UFO: A public service corporation, the Civil Aviation Authority was established by the British Parliament in 1972 as a specialist aviation regulator and provider of air traffic services. Following its separation from the National Air Traffic Services in 2001, the CAA became the U.K.’s independent aviation regulator, with all civil aviation functions (such as economic regulations; airspace policy; safety regulations; and consumer protection) integrated within a single, unified body. The CAA has declassified into the public domain a number of documents that tell of extraordinary encounters with UFOs, as the following, startling extract demonstrates: “12 Jun 82 Dinkelsbuhi – Large translucent object 500 feet long at 41,000 feet. ATCC [Air Traffic Control Center] requested subject aircraft to investigate this object which was found to have the form of a double rectangle surmounted by a globe (egg shape) crowned by a silver cone. Object observed by all on board.” The strange saga of this absolutely huge UFO was never figured out.

August 18, 1983: A Spotted UFO: “18 Aug 83 Florence – Unidentified flying object seen by crew. Large black object, balloon shaped with large white spot on it, observed 10 NM SE of Firenza. No attachments to object. SUPP. INFO.: Italian CAA replied no met [meteorological] balloon could possibly have been present at the indicated place or time.” Prepared by the staff of the UK’s Civil Aviation Authority in the summer of 1983, this particular report, although brief, clearly demonstrates something very unusual was seen in the skies of Florence. Precisely what was seen, however, remains unknown. Here's another: August 21, 1986: A cigar-shaped UFO and an official document. The following is extracted from a notable file on UFOs prepared by the UK’s Civil Aviation Authority in the 1980s: “21 Aug 86 Belgrade – Non UK Airmiss missile type object passed 500 ft above on reciprocal track A/C heading 290 MAG at FL 390. Object was black, cigar shaped, without wings. Belgrade radar informed on RTF. CAA closure – foreign authority advised.”

And, finally: February 9, 1962: A flying saucer and engine trouble. In February 1962, an employee of the UK Royal Air Force Police – one Sergeant C.J. Perry – was ordered to investigate a then-recent, extraordinary UFO report. The documentation prepared by Perry is now in the public domain. It tells an intriguing story: “At Aylesbury on 16th February 1962, at 1530 hrs., I visited the Civil Police and requested information on an alleged ‘Flying Saucer’ incident. I was afforded every facility by the Civil Police authorities and although no official report had been made, details of the incident were recorded in the Station Occurrence book. “The details are as follows: Mr. Ronald Wildman of Luton, a car collection driver, was traveling along the Aston Clinton road at about 0330 hrs. on 9th February 1962 when he came upon an object like a hovercraft flying approximately 30 feet above the road surface. As he approached he was traveling at 40 mph but an unknown force slowed him down to 20 mph over a distance of 400 yrd., then the object suddenly flew off.

“He described the object as being about 40 feet wide, oval in shape with a number of small portholes around the bottom edge. It emitted a fluorescent glow but was otherwise not illuminated. Mr. Wildman reported the incident to a police patrol who notified the Duty Sergeant, Sergeant Schofield. A radio patrol car was dispatched to the area but no further trace of the ‘Flying Saucer’ was seen. It was the opinion of the local police that the report by Mr. Wildman was perfectly genuine and the experience was not a figment of imagination. They saw that he was obviously shaken.“I spoke to Sergeant Schofield and one of the Constables to whom the incident was reported. Both were convinced that Mr. Wildman was genuinely upset by his experience.”

February 23, 1975: A spiky UFO: Mavis Allen had a very strange encounter on a particular morning in 1975, in an area of woodland in central England. As Mavis walked her dog through woods near the town of Rugeley, she was amazed to see a circular, black-colored object rolling along the ground in front of her. It was around six feet in circumference and had four protrusions (that Allen referred to as “spikes”) that stuck out from equal points around the middle. Allen stopped in amazement as the object rose slowly and silently, to a height of around fifteen feet and which then shot away at a fast pace. 

May 1, 1994:  A “Boomerang” attracts official, secret attention: Under the terms of the UK Freedom of Information Act, the following, brief extract from a much longer, and still withheld, file offers the following, tantalizing insight: “1 May 1994 – Sighting of unusual object. Member of public reported seeing a black boomerang-shaped object, which appeared to hover over RAF Northolt, above 30,000 feet, before tumbling approx 2000-3000 feet, while rotating through 180 degrees on its axis. No other reports of anything unusual received – possibly A/C in Bovingdon stack seen from odd angle in setting sun.” What all of this tells us is that reports in the skies of our world, concerning mainly small objects, is nothing new at all. Of course, none of these "things" can be said to military craft, unknown objects or alien spacecraft. Yet, what we're saying now was being done decades ago.

 BY ANDY TOMASWICK

Researchers from various institutions in China, America, Abu Dhabi, and Japan think they might have an answer. They found that a very fast migration of Jupiter from the inner solar system to its current orbital path could result in the divergent numbers of asteroids at its stable gravitational points. Given that Jupiter is one of the two lodestars of the Trojan system (the other being the Sun), that seems a plausible scenario.

Partly that is due to some previous theories that are beginning to gain some credence among the scientific community. The Grand Tack Hypothesis, which suggests that Jupiter formed slightly further out than Earth, then came inwards in the solar system and was catapulted (at high speeds) out to its current orbital path, seems to fit the bill nicely for exactly this kind of fast migration. In fact, that fast migration is exactly the kind of event that could potentially cause this uneven distribution, so this research could be thought of as a point toward confirmation of the Grand Tack Hypothesis itself.

In order to prove their own theory, though, the researchers did as all good researchers would do when they lack experimental evidence – they developed a model. This particular model focuses on how Jupiter’s orbit has evolved since its inception and, in particular, what impact that has on the local asteroid population. The findings from the model were in line with the expected values for the population of the Greek and Trojan asteroids. 

However, there are some downsides to this model. In particular, it doesn’t account for what, if any, other evolutionary aspects of the solar system might have had on the Trojan’s formation. There are plenty of other models that do account for such evolutionary aspects, so maybe someone in the near future will be able to combine the broader solar system models with the Jupiter-specific ones and see what kind of impact it has on the distribution of the asteroids. After all, the more we understand about our early solar system, the better.

Latest UFO Sightings: Strange Objects Spotted in Olympia, Washington on Valentine’s Day

On the evening of February 14, 2023, some residents of Olympia, Washington, reported seeing mysterious lights and objects in the sky. According to one witness, who captured the incident on video, the UFOs appeared to be moving in unusual patterns and directions, and were not easily explainable as any known aircraft or natural phenomenon. The witness also ruled out the possibility that the objects were from a nearby airport or military base, as they were seen in a different direction and distance.

The footage shows five glowing orbs hovering and moving above the cityscape. The color and intensity of the lights vary, and seem to pulsate or flicker at times. In one clip, the UFOs seem to merge and split, or change their shape and size, while emitting a humming or buzzing sound. In another clip, the lower object appears to make a sudden turn or jump, as if avoiding something or adjusting its trajectory.

The witness said that he had never seen anything like this before, despite living in the same building for almost two years. The witness also noted that the distance between Olympia and Seattle airport, which is the closest major airport, is about 55 miles, and that there were no other visible planes or helicopters in the area at the time of the sighting. The witness encouraged others to come forward and share their experiences, and hoped that experts or investigators could shed some light on what the UFOs might be.

UFO Mania: Experts Warn of Impending UAP Sightings Wave in the UK

Are we alone in the universe? That’s a question that has fascinated people for generations. Recently, there has been renewed interest in UFO sightings after four flying objects were shot down over North America, three of which remain unidentified. This has led experts to suggest that the UK (and of course other countries in Europe) could be about to experience a wave of sightings in its skies.

Joe McGonagle, an amateur UFO researcher in the UK, claims that the recent news about alien life has caused people in the country to start thinking about it. However, he advises against jumping to conclusions.

Despite the increasing number of UFO sightings, according to McGonagle, many of these will remain unsolved. He believes that there is a wide range of plausible explanations behind these sightings, and he claims that people like himself are more likely to know about it than the authorities. For decades, he has been studying classified documents about the Ministry of Defence to gain a deeper understanding of the phenomenon.

However, even evidence to the contrary is often not enough to deter the most ardent alien hunters from their belief in a conspiracy to keep sightings secret. The increased press coverage of UFO sightings is likely to lead to a rash of reports from people who don’t usually look at the sky. As McGonagle warns, this can create a self-fulfilling cycle where people start to see things they don’t recognize, report them, and then spark an alien invasion rumor.

So keep looking up, and who knows what we might see?

This artist's conception illustrates a supermassive black hole (central black dot) at the core of a young, star-rich galaxy. Now astronomers have found a rogue SMBH travelling through space.

Astronomers Spot a Rogue Supermassive Black Hole, Hurtling Through Space Leaving Star Formation in its Wake

Supermassive black holes (SMBHs) lurk in the center of large galaxies like ours. From their commanding position in the galaxy’s heart, they feed on gas, dust, stars, and anything else that strays too close, growing more massive as time passes. But in rare circumstances, an SMBH can be forced out of its position and hurtle through space as a rogue SMBH.

In a new paper, researchers from Canada, Australia, and the USA present evidence of a rogue SMBH that’s tearing through space and interacting with the circumgalactic medium (CGM.) Along the way, the giant is creating shock waves and triggering star formation.

The paper is “A candidate runaway supermassive black hole identified by shocks and star formation in its wake.” The lead author is Pieter van Dokkum, Professor of Astronomy and Physics at Yale University. The paper hasn’t been peer-reviewed yet.

If you’ve never heard of a runaway SMBH, you’re not alone. SMBHs are normally locked into place at the centers of galaxies, and that’s where they stay. But scientists think that in rare circumstances SMBHs can escape their galaxies. In their paper, the authors explain how an SMBH can be cast out of its host galaxy.

It always starts when galaxies merge. That leads to the formation of a binary SMBH at the center of the merger remnant. The binary SMBH can be very long-lived, surviving for as long as one billion years before merging. If during that time, a third SMBH reaches the galactic center, then a three-body interaction can give one of the SMBHs a velocity boost, and it can be driven from the galaxy.

But despite their theoretical underpinnings, finding these rogue SMBHs is difficult. Astronomers identified one of the best candidates in 2021, about 230 million light-years away. The authors noticed peculiar movement and velocity that indicated recent disruption. But they couldn’t conclude whether they saw an ongoing galaxy merger, a binary black hole system, or a gravitational-wave recoil event.

Astronomers recognize a couple of ways that they can identify a runaway SMBH. The easiest way is if the hole is actively absorbing material as an active galactic nucleus and can be identified by its luminosity. “For such objects,” the authors write, “the presence of an SMBH is not in doubt, but it can be difficult to determine whether they are ‘naked’ black holes or the nuclei of merging galaxies.”

Another way is by the stellar mass that the rogue hole drags along with it. When an SMBH is ejected, its massive gravitational power pulls some stars along with it. But without the luminosity from an AGN, the dimness makes identifying the hole and its stellar companions difficult from a great distance.

A third way that astronomers could recognize a potential rogue SMBH is by the effect it has on the difuse gas in the circumgalactic medium (CGM) as it passes through it.

“The interaction of a runaway supermassive black hole with the CGM can lead to the formation of a wake of shocked gas and young stars behind it,” the authors write. In their paper, they report the serendipitous discovery of a linear feature in images from the Hubble’s Advanced Camera for Surveys that could be one of these wakes.

When an SMBH travels through ionized hydrogen in the CGM, it produces a shock front with a long wake trailing behind it. In the wake, clouds of shocked gas can cool and form stars that look like knots in the trail. The researchers analyzed three of the knots in the linear feature and measured their ages and metallicity.

Theory and modelling show that the youngest stars formed in the wake should be younger than about 30 million years old. When the researchers measured their properties, they found that the three knots are within the age range laid out by models. They’re also within the range of metallicities and dust content.

If the host galaxy ejected an SMBH, the galaxy should show signs of disruption. SMBHs are extraordinarily massive, and that much mass can’t move through a galaxy without shaping it. The team examined the galaxy that spawned the rogue SMBH and found that its morphology was disrupted.

There is, however, another possible explanation for the linear feature. It could be a black hole jet rather than a rogue SMBH. Under the right conditions, black hole jets can also shock gas in the CGM and lead to star formation. “There are two well-studied nearby examples of jets triggering star formation,” the authors state. One of them is called Minkowski’s Object.

The authors acknowledge the black hole jet explanation as a possibility, but they say there are too many problems with it. Visible emission lines aren’t a property of black hole jets, and there’s no evidence of nuclear activity. There’s also a problem with morphology. “A more serious issue is that the morphology of the feature does not match simulations or observations of jet-induced star formation,” the authors explain.

They settle on a runaway SMBH as the best explanation for the data and observations.

“The line ratios, colours, and the overall morphology are consistent with an ejected SMBH moving through the CGM at high speed while triggering star formation,” they write.

Locating the black holes would be incontrovertible evidence for this conclusion. “The ‘smoking gun’ evidence for this scenario would be the unambiguous identification of the black holes themselves,” the researchers write. “The obvious places to look for them are A and B in Fig. 6.”

“These are candidates for ‘hyper compact stellar systems,'” SMBHs enveloped in stars and gas that escaped with them,” they explain.

The long feature in these observations is highly unusual, so it won’t be a surprise if it has an unusual cause. Only more observations can determine if rogue SMBHs are at work, and the JWST could provide them. “Deeper data, for instance, from the JWST NIRSPEC IFU, may show the expected broad, highly red- or blueshifted emission lines of ionized gas that is bound to the black holes themselves. Those data could also spatially resolve flows, shocks, and star formation near A,” the authors say, looking ahead.

And if there is one instance of runaway SMBHs creating these features, there will be others.

“Looking ahead, the morphology of the feature in the HST images is so striking that it should not be too difficult to find more examples if they exist. Future data from the Nancy Grace Roman telescope can be searched with automated algorithms,” they explain.

A rogue SMBH disconnected from its galaxy and roaming through the circumgalactic medium is a fascinating phenomenon. We’re only in the early stages of understanding SMBHs, how they’re linked with galaxy growth, and how they merge to produce gravitational waves.

To find that they can be kicked out of their host galaxies adds a layer of complexity only nature could come up with.

A dramatic fireball lit up European skies just hours after its discovery in space.

Krisztián Sárneczky spotted the small asteroid at Konkoly Observatory's Piszkéstető Station, located some 60 miles (100 kilometers) northeast from Budapest, with a 2-foot (0.6-meter) telescope. The information was passed along to the European Space Agency, hours before it fell into the atmosphere around 10 p.m. EST Feb. 12 (0300 GMT Feb. 13).

"I discovered this small body during a routine NEO [near Earth object] hunt," Sárneczky told Space.com senior writer Tereza Pultarova in an e-mail. "It was immediately obvious that it was an NEO, but it wasn't particularly fast across the sky, as it was heading right towards us, and it was faint," Sárneczky added.

It's not the first time Sárneczky has given a heads-up for a dramatic fireball event, as the professional asteroid hunter did the same thing in March 2022. "At the time I thought it was a once-in-a-lifetime event," he said. "I was wrong."

US Military Downs 4 Unidentified Flying Objects; Officials Do Not Dismiss Possibility of Extraterrestrial Origin

The U.S. military has shot down four unidentified high altitude objects in just eight days, prompting speculation about their nature and purpose. The latest takedown occurred over Lake Huron, with President Joe Biden ordering the action on the grounds that the object posed a potential surveillance threat. However, despite enhanced radar and other measures, officials remain in the dark about the nature of the objects, leading to calls for greater transparency from lawmakers. While defense officials deny that the objects are related to aliens, the lack of information has fueled anxiety and speculation about the potential for extraterrestrial life.

The recent events have been described as “nothing short of craziness,” with military leaders struggling to determine what is out there and what the dangers might be. The repeated takedowns are believed to be a response to a spy balloon from China that emerged over U.S. airspace in late January, but officials remain cautious about ruling out UFOs. While some have criticized the military for being trigger happy, others have argued that this is preferable to the permissive approach taken towards the Chinese spy balloon.

Despite the lack of concrete information, the situation has sparked widespread interest in UFO sightings, with many people searching for the latest news and updates. While the truth about these sightings may remain shrouded in mystery for now, the search for answers continues, as military officials and lawmakers work to uncover the truth about these high-flying objects.

 BY MATT WILLIAMS

The first SETI survey (Project Ozma) was conducted in 1960 and was led by famed astrophysicist Dr. Frank Drake (who proposed the Drake Equation). This survey relied on the Green Bank Observatory‘s 26-meter (85-foot) radio telescope to listen for radio transmissions from the nearby star systems of Tau Ceti and Epsilon Eridani. Since then, the vast majority of SETI projects have been geared towards the search for radio technosignatures, owing to the ability of radio waves to propagate through interstellar space. As Dvali and Osmanov explained to Universe Today via email:

“Currently, we are mainly looking for radio messages, and there have been several attempts to study the sky for finding the so-called Dyson sphere candidates – megastructures built around stars. On the other hand, the problem of SETI is so complex that one should test all possible channels.

“A whole “spectrum” of technosignatures might be much wider: for instance, the infrared or optical emission from megastructures also built around pulsars, white dwarfs, and black holes. A completely new “direction” must be the search for an anomalous spectral variability of these technosignatures, which might distinguish them from normal astrophysical objects.”

For many researchers, this limited focus is one of the main reasons SETI has failed to find any evidence of technosignatures. In recent years, astronomers and astrophysicists have recommended extending the search by looking for other technosignatures and methods – such as Messaging Extraterrestrial Intelligence (METI). These include directed energy (lasers), neutrino emissions, quantum communications, and gravitational waves, many of which are spelled out in the NASA Technosignature Report (released in 2018) and at the TechnoClimes 2020 workshop.

For their study, Dvali and Osmanov suggest looking for something altogether different: evidence of large-scale quantum computing. The benefits of quantum computing are well-documented, which include the ability to process information exponentially faster than digital computing and being immune to decryption. Given the rate at which quantum computing is advancing today, it is entirely logical to assume that an advanced civilization could adapt this technology to a much grander scale. Said Dvali and Osmanov:

“No matter how advanced is a civilization or how different is their particle composition and chemistry from ours, we are unified by laws of quantum physics and gravity. These laws tell us that the most efficient storers of quantum information are black holes. 

“Although our recent studies show that theoretically, there may exist devices created by non-gravitational interactions that also saturate the capacity of information storage (so-called “saturons”), the black holes are the clear champions. Correspondingly, any sufficiently advanced ETI is expected to use them for information storage and processing.”

This idea builds on the work of Nobel-prize winner Roger Penrose, who famously proposed that limitless energy could be extracted from a black hole by tapping into the ergosphere. This space lies just outside the event horizon, where infalling matter forms a disk that is accelerated to near the speed of light and emits tremendous amounts of radiation. Several researchers have suggested that this may be the ultimate power source for advanced ETIs, either by feeding matter onto an SMBH (and harnessing the resulting radiation) or simply harnessing the energy they already put out.

Two possibilities for this latter scenario involve harnessing the angular momentum of their accretions disks (the “Penrose Process“) or capturing the heat and energy generated by their hypervelocity jets (perhaps in the form of a Dyson Sphere). In their later paper, Dvali and Osmanov suggest that black holes could be the ultimate source of computation. This is based on the notions that: a) a civilization’s advancement is directly correlated to its level of computational performance, and b) that there exist certain universal markers of computational advancement which can be used as potential technosignatures
for SETI.

Using the principles of quantum mechanics, Dvali and Osmanov explained how would be the most efficient capacitors for quantum information. These black holes would likely be artificial in nature and micro-sized rather than large and naturally occurring (for the sake of computing efficiency). As a result, they argue, these black holes would be more energetic than naturally-occurring ones:

“By analyzing the simple scaling properties of information retrieval time, we showed that the optimization of the information volume and processing time suggests that it is maximally beneficial for ETI to invest energy in the creation of many microscopic black holes as opposed to a few large ones.

“First, the micro-black holes radiate with much higher intensity and in the higher energy spectrum of Hawking radiation. Secondly, such black holes must be manufactured by means of high-energy particle collisions in accelerators. This manufacturing necessarily provides an accompanying high-energy radiation signature.”

In honor of Dr. Stephen Hawking, the COSMOS center will be creating the most detailed 3D mapping effort of the Universe.

Hawking radiation, named in honor of the late and great Stephen Hawking, is theorized to be released just outside the event horizon of a black hole due to relativistic quantum effects. The emission of this radiation reduces the mass and rotational energy of black holes, theoretically resulting in their eventual evaporation. The resulting Hawking radiation, said Dvali and Osomanov, would be “democratic” in nature, meaning that it would produce many different species of subatomic particles that are detectable by modern instruments:

“The great thing about Hawking radiation is that it is universal in all the existing particle species. Thereby, ETI quantum computers must radiate “ordinary” particles such as neutrinos and photons. Neutrinos, in particular, are excellent messengers due to their extraordinary penetration ability, which avoids the possibility of screening.

“This, in particular, offers novel fingerprints of ETI in the form of a flux of very high energy neutrinos coming both from Hawking radiation of information storing micro black holes as well as from the collision ‘factories’ that manufacture them. The Hawking component of radiation is expected to be a superposition of black body spectra of very high energies. In the paper, we have shown that the IceCube observatory can potentially observe such technosignatures. However, this is just one potential example of a very exciting new direction for SETI.”

In many respects, this theory echoes the logic of the Barrow Scale, proposed by astrophysicist and mathematician John D. Barrow in 1998. A revision of the Kardashev Scale, the Barrow Scale suggests that civilizations should be characterized not by their physical mastery of outer space (i.e., planet, solar system, galaxy, etc.) but of inner space – i.e., the molecular, atomic, and quantum realms. This Scale is central to the Transcension Hypothesis, a proposed resolution to Fermi’s Paradox that suggests that ETIs would have “transcended” beyond anything we would recognize.

Herein lies another exciting aspect of this theory, which is how it offers another possible resolution to the Fermi Paradox. As they explained:

“Up until now, we have completely overlooked a natural direction for SETI in form of high energy neutrinos and other particles produced by the Hawking radiation of artificial black holes. Thereby, various experimental searches for such high energy particles can potentially shed an extremely important light on the presence of advanced ETI within the observable part of the Universe.”

In short, it could be that we see a “Great Silence” when we look into the cosmos because we’ve been looking for the wrong technosignatures. After all, if extraterrestrial life has had a jump on humanity (which seems reasonable given the age of the Universe), it stands to reason they would have outgrown radio communications and digital computing a long time ago. Another advantage to this theory is that it need not apply to all ETIs to explain why we haven’t heard from any civilizations to date.

Given the exponential rate at which computing progresses (using humanity as a template), advanced civilizations might have a short window in which they broadcast in radio wavelengths. This is a key part of the Drake Equation: the L parameter, which refers to the length of time civilizations have to release detectable signals into space. In the meantime, this study offers another potential technosignature for SETI surveys to look for in the coming years. The Paradox persists, but we need only find one indication of advanced life to resolve it.

Latest update on the unidentified objects flying over the US and Canada: 

Yesterday the US Airforce has shot down another unidentified flying object, this time the object was shot down over Lake Huron and they are going to recover the debris to analysis the object. 

The Pentagon has refused to rule out the recent unidentified objects shot out of the sky could be aliens. US Air Force General Glen VanHerck said intelligence services were exploring all avenues - including the three most recent objects may be linked to extraterrestrials.

Asked whether he had ruled out 'aliens or extraterrestrials', he said: 'I'll let the intel community and the counterintelligence community figure that out. I haven't ruled out anything' reports the Dailymail. 

It seems as that the US air force has more information about these mysterious objects and although they refuse to give an explanation, the statement of US Air Force General Glen VanHerck is remarkable. 

Next, it seems that China will also have to deal with these unidentified flying objects. Sky News Asia Correspondent Brent O’Halloran says the Chinese authorities are considering shooting down an unidentified flying object after it was “detected” near a “port city” in the Northern Shandong province. 

So far; 

02-04-2023: Chinese Spy Balloon shot down off the coast of South Carolina 

02-10-2023: Airborne object shot down over Alaska, Dead Horse 

02-11-2023: Airborne object shot down over Northern Canada near Mayo, Yukon 

02-11-2023: Airborne object detected on radar over Montana 

02-12-2023: Airborne object show down over Lake Huron 

The next three videos provide an update on the latest development on these unidentified flying objects whereby the third video from MRMBB333 provides more detailed insight including footage of a transport of a UFO-like object and a footage of a series of unidentified objects flying over the Argentine Sea.

The website UFO Stalker says "This domain has temporarily been seized by the Department of Defense in coordination with the Department of Homeland Security and Department of Justice in support of an ongoing investigation related to the unidentified aerial phenomena occurring within North American Airspace." 

With all the strange things going on in the skies over US and Canada, US Airforce shooting down unknown flying objects and now the Department of Defense has been seized the well known website UFO Stalker who reports UFO sightings on daily base. 

Are more websites and YouTube channels who are reporting about the UFO phenomenon to be seized in the near future? 

In the meantime a fourth unknown flying object has been shot down over Lake Huron yesterday and also a new unknown flying object has been detected over Canada. 

The fact that the Pentagon said that they cannot rule out that the unknown objects flying over the US and Canada are Aliens is something to think about. 

Maybe it is too far fetched but could it be that they are preparing a false flag alien invasion, and they don't want UFO related websites and YouTube channels reporting about it? We may wonder whether more UFO related websites and YouTube channels will be seized soon, something is going on for sure.
