Sometimes Astronomy isn’t About What you see, but What you don’t see
Sometimes Astronomy isn’t About What you see, but What you don’t see
Constraints are critical in any scientific enterprise. If a hypothesis predicts that there should be an observable phenomenon, and there isn’t any trace of it, that’s a pretty clear indication that the hypothesis is wrong. And even false hypotheses still move science forward. So it is with astronomy and, in particular, explorations of the early universe. A paper authored by researchers at Cambridge and colleagues now puts a particularly useful constraint on the development of early galaxies, which has been a hot topic in astronomy as of late.
Part of the reason that has been a hot topic is that, for the first time, we’re starting to get telescopes capable of peering back that far. The James Webb Space Telescope sparked much hope for being able to peer back to the earliest stars. However, while that instrument is still going through its data collection phase, plenty of other highly capable telescopes can provide some insight as well.
One of those is the SARAS3 radio telescope, which is deployed over a lake in India. It monitored some of the light coming from the earliest galaxies and provided data to the team from Cambridge, who analyzed it, looking for one defining feature.
UT video on the early universe.
Known as the 21-cm hydrogen line, this is the spectrum that hydrogen emits when its electron changes state. It’s been used consistently in Early Universe Cosmology since its discovery in the 1940s, largely because it can make its way through the cloudy dust that shrouds the volume of the early universe. That ability also makes it capable of passing effortlessly through Earth’s atmosphere, allowing it to be easily detected by a ground-based telescope like SARAS3.
What was notable in the Cambridge paper was the lack of the 21-cm line. In fact, this common line that is so widely used in other parts of cosmology seemed to be absent from the galaxies that existed only 200 million years after the Big Bang.
With that constraint, the authors were able to do two things. One was disproving a tentative finding from another research group. The other was defining some of the significant characteristics of those galaxies.

Another research group led by Arizona State University and the Massachusetts Institute of Technology published another paper in 2018 using data from the EDGES radio telescope in Australia. That paper detailed a possible detection of some of the light from the earliest galaxies in the universe. It also threw a wrench into one of the early models of cosmological expansion, which didn’t expect such a detection. Now data from this new paper casts some doubt on that finding, though there still needs to be additional independent confirmation of it.
When defining the characteristics of galaxies, one crucial factor is how bright they are. The lack of a 21-cm line points to a simple fact – they weren’t very bright. Or at least not thousands of times more luminous than galaxies are today. If they were, the 21-cm line should have been powered enough to show through the haze and be detectable in the SARAS3 data. Other constraints detailed in the paper include the masses of those galaxies, as well as their efficiency at heating up hydrogen.
All this means for cosmology is simply that more data is needed, and two experiments are coming up soon that should provide it. In addition to the JWST, there is a project called the Radio Experiment for the Analysis of Cosmic Hydrogen (REACH), which is expected to present results sometime next year. Until then, astronomers are gathering a clearer picture of the early universe, even if it’s from the lack of an expected signal.
NASA chief hopes UFOs spotted by pilots are evidence of alien life
NASA chief hopes UFOs spotted by pilots are evidence of alien life
Bill Nelson
NASA’s chief scientist believes that there are extraterrestrial life beings out there. According to Bill Nelson, he hopes that the sightings of UFOs don’t turn out to be an anomaly on Earth, and he thinks that they could be evidence of life.
Bill, who became NASA’s administrator in May 2021, was talking to Larry Sabato, a political science professor at the University of Virginia, about his thoughts on the various UFO sightings that have been reported. One particular incident that he talked about was the 2004 incident involving Navy pilots Alex Dietrich and Dave Fravor.
The pilots of the USS Princeton were training on the day of the incident, and they were alerted to the strange objects flying around them. They then went to investigate and saw an object that looked like a floating object with no markings.
According to Bill Nelson, the object accelerated as it flew away, and it was 60 miles away in less than two seconds flat. He then believes that the most likely explanation for the sightings is alien life. He claims that the pilots have reported seeing something, but they don’t know what it is.
He then claims that the object flew past the technological capabilities of an enemy on Earth. He believes that the possibility of alien life is more likely due to the universe’s massive size. He also noted that there are various theories suggesting that other universes exist.
If aliens exist, Earth is the only place where they are organized and civilized. I believe that there are other planets with intelligent life forms out there, too, as the universe is so big. Men In Black movies were onto something.
Bill’s interview with NASA’s chief scientist recently went viral, and people were very happy to support his theory about alien life. Many people on Reddit agreed with Nelson’s belief that there is a high probability of life being found outside Earth.
One person stated that it was a height of ignorance for people to believe that Earth is the only place where extraterrestrial life is.

Spinning around our Sun are nine planets, more than 120 moons, millions of asteroids and other rocky objects, and countless comets. Together, they make up the Solar System, our home in this vast universe. Closest to the sun lies Mercury, followed by Venus, Earth and Mars. These planets are known as the Inner Planets of our Solar System.
All the planets in our Solar System are unique in an unusual way and each of them has a notable characteristic feature unique to them. The Earth sustains life to grow, while venus receives rain of extremely corrosive Sulphuric Acid. All Planets in our Solar System are surrounded by their mini planets, or better to say, their Satellites, which revolve around them in certain fixed orbits. The orbits can be distinguished and recognised by using Kepler's Laws of motion.
The moon is the closest celestial body to the Earth. It is Earth’s only natural Satellite. Most satellites are much smaller than their parent planet. Earth has only one Satellite, Mars has two Satellites, and Jupiter has about 80 of them, including the largest satellite in our Solar System, Ganymede. Saturn has more than eight two moons. Uranus has twenty-seven Satellites, while Neptune has about fourteen of them. Even our dwarf neighbour, Pluto, has five Satellites revolving around it. However, the first two planets of our Solar System, Mercury and Venus, surprisingly, do not possess moons. But, Why? Why are only the first two Planets exception to this characteristic feature? And How exactly were the Satellites formed?
In this video, we will have a detailed study of Satellites and the Factors affecting the formation of Satellites. Before we continue, make sure you like, subscribe to our channel and hit the bell icon for further engrossing topics like these.

Elon Musk: "EVERYONE'S Lying!! People Don't Realize It About Pyramids!
The ancient pyramids of Egypt have been the subject of mankind's fascination for centuries now. These historic masonry structures are sprinkled across the Egyptian landscape and are living proof that the ancient Egyptian civilization was way more advanced than archeologists and historians previously thought. In the past, there have been many speculations and theories regarding how these pyramids came into being. Some of these were simple, having a logical approach that laborers built the pyramids that were designed by some incredibly talented architects. However, there are also some people who think outside of the box, a few among them have even proposed that these pyramids, especially the ones in Giza, were constructed by extraterrestrial beings. And believe it or not, the incredibly famous tech billionaire Elon Musk is among the people who believe the alien theory

James Webb Just Detected A Huge Structure Older Than The Universe!
The big bang is one of the most fascinating topics you can bring up when conversing with scientists and astronomers. This is because the theory talks about how the whole universe started in the first place. However, the event that led to the big bang is one thing that is being argued among scientists today.
For this reason, the James Webb Telescope was called in to make some findings about the big bang. The JWST found something quite alright, but it wasn't something the scientist had prepared their minds for. What did the James Webb Telescope discover, and in what way would it affect the Big Bang Theory?
Join us as we explore the James Webb telescope's terrifying discovery before the big bang.
It all began when an astronomer sighted a discovery made by the James Webb Telescope. Astronomer Rohan Naidu was at home with his girlfriend when he discovered the galaxy that almost broke cosmology. He was inspecting some of the images the James Webb Telescope sent earlier when one of the images caught his attention. The telescope had identified an object that Naidu recognized as mysteriously huge. It dates back to the big bang era, making it older than any galaxy we once knew in science. It was a shocking discovery for him, as he called his girlfriend to observe the most distant starlight too. He was praised for this discovery by his team, and then they got to work. A few days later, Naidu and his team published a paper on the discovered galaxy called "GLASS-z13." It was a discovery that had the whole world of science come to a standstill, as no one expected such a discovery to be made by the James Webb Telescope.
The James Webb Telescope made this ancient galaxy discovery just a few weeks after it went into operation. It was a huge achievement because if such a discovery could be made a few weeks into the telescope's launch, what next would it discover? The JWST, the most powerful telescope currently in use by scientists and astronomers and the Hubble Space Telescope's successor, was built to make us understand our universe better, and it is already achieving that feat. The telescope is 1.5 million kilometers away from earthly interference, where it orbits the sun. It is equipped with a sunshade about the size of a tennis court, with huge segmented mirrors and very sensitive tools designed to detect details about the universe and its entirety that have never been explored.

Mysteriously bright flash that gave off more light than 1,000 TRILLION suns was caused by a star being 'squeezed like a toothpaste tube' by a supermassive black hole, study finds
Mysteriously bright flash that gave off more light than 1,000 TRILLION suns was caused by a star being 'squeezed like a toothpaste tube' by a supermassive black hole, study finds
Scientists detected a mysteriously bright flash of light in outer space in February
It is thought to be a beam of matter extending from a supermassive black hole
This occurred when the black hole devoured a star in a 'tidal disruption event'
It was brighter than a trillion suns and light had travelled eight billion light-years
A mysteriously bright light in the sky was caused by a distant star being 'squeezed like a toothpaste tube' by a supermassive black hole, a study has found.
Astronomers at the Zwicky Transient Facility in California were mystified when they detected a flash that gave off more light than a trillion suns back in February.
Now, the team has revealed that the light was the result of a tidal disruption event (TDE), where a star wanders a little too close to a black hole and is ripped apart by its gravitational forces.
It is being dubbed one of the most violent events in the universe - reaching 54,000°F (30,000°C) - and is the brightest TDE ever witnessed from Earth.
Astronomers at the Zwicky Transient Facility in California were mystified when they detected a flash that gave off more light than a trillion suns back in February.
When a star gets too close to a black hole, it undergoes 'spaghettification' - where it is stretched vertically and compressed horizontally by the strong gravitational field.
These are known as a tidal disruption events, or TDEs, and emit light, radio and other waves for up to a few weeks or months while they occur.
This is because, eventually, the elongated material spirals around the black hole and heats up, creating a flash that astronomers can detect millions of light years away.
The event has been named AT2022cmc, and occurred more than eight billion light-years away - over halfway across the universe - making it the furthest TDE ever detected.
Data collected from it could help shed new light on how supermassive black holes feed and grow.
The flash was first detected during a routine all-sky survey, and was identified as a jet of light pointing directly toward Earth, known as a 'jetted TDE'.
After the star was destroyed, an outflow of matter streaked out of the black hole at close to the speed of light, extending along its axis of rotation.
This emitted X-ray radiation, which was absorbed by dust surrounding the black hole, and re-emitted as infrared radiation, radio waves and visible light.
The jet's unusual brightness and alignment towards Earth allowed instruments across the world to capture it in extraordinary detail, despite its huge distance away from us.
These included the Liverpool Telescope in Spain and European Southern Observatory's Very Large Telescope in Chile.
Nial Tanvir from the University of Leicester, who was involved with the analysis, said: 'We have only seen a handful of these jetted-TDEs and they remain very exotic and poorly understood events.'

WHAT HAPPENED DURING 'AT2022cmc'?
A star more than more than eight billion light-years away from Earth wandered too close to a black hole, and was sucked in.
After it was destroyed, an outflow of matter from the dying star extended along the black hole's axis of rotation, and emitted X-ray radiation.
The X-rays were absorbed by dust surrounding the black hole, and re-emitted as infrared radiation, radio waves and visible light.
Dr Daniel Perley, a co-author from Liverpool John Moores University, said that AT2022cmc was an 'extraordinary' type of TDE that 'didn't seem to match any known type of celestial source'.
He said: 'The most known types of explosions are either much faster, much slower, or much bluer in colour than inferred from the data.
'Usually, intense gravitational forces tear the star apart, transforming it into a superheated disk of gas which eventually disappears into the black hole.
'However, in this case, something happened that ejected matter almost at the speed of light back into space.
'The way we describe it is as a toothpaste tube being squeezed suddenly in the middle causing the contents to squirt matter out of both ends.
'Then, as the material collides with surrounding gas, the intense optical, radio, and X-ray emission is produced.'
The research team were able to 'catch this event right at the beginning, within one week of the black hole starting to feed on the star', according to co-author and astrophysicist at the Massachusetts Institute of Technology (MIT) Dr Dheeraj Pasham.
It also marked the first time a jetted TDE has been detected from optical light.
Dr Perley added: 'Until now, the small number of jetted-TDEs that are known were initially detected using high energy gamma-ray and X-ray telescopes.'
AT2022cmc marks the first time a jetted TDE has been detected from optical light.
Pictured: Liverpool Telescope in Spain, which picked up some radiation from the jetted TDE
After the initial discovery of AT2022cmc, researchers looked at it with the Interior Composition ExploreR (NICER), an X-ray telescope on board the International Space Station.
They found that the source of the radiation was 100 times more powerful than the strongest ones ever detected.
Dr Benjamin Gompertz, from the University of Birmingham and who led this analysis, said: 'As bright as they are, there is only so much light a collapsing star can produce.
'Because AT 2022cmc was so bright and lasted so long, we knew that something truly gargantuan must be powering it – a supermassive black hole.'
His team concluded that the extreme X-ray activity is the result of the shredded star creating a whirlpool of debris as it fell into the black hole.
'It's probably swallowing the star at the rate of half the mass of the sun per year,' Dr Pasham estimates.
After the initial discovery of AT2022cmc, researchers looked at it with the Interior Composition ExploreR (NICER), an X-ray telescope that operates aboard the International Space Station (pictured)
The results of the analysis of AT2022cmc have been published today in two papers in Nature and Nature Astronomy.
The last time scientists detected a jetted TDE was well over a decade ago, and it is still a mystery as to why some TDEs launch jets and some do not.
It is thought to be linked to the rate the star's matter is spinning around the black hole as it is destroyed, and a particularly rapid spin can power the luminous jets.
As more powerful telescopes are launched, astronomers say they may be able to observe more TDEs and get some answers.
Here's an illustration showing what redshift basically does to the light coming from galaxies moving away from Earth.
NASA/JPL-Caltech//R. Hurt (Caltech-IPAC)
Dr Dr Matteo Lucchini, a co-author from MIT said: 'We expect many more of these TDEs in the future.
'Then we might be able to say, finally, how exactly black holes launch these extremely powerful jets.'
WHAT'S INSIDE A BLACK HOLE?
Black holes are strange objects in the universe that get their name from the fact that nothing can escape their gravity, not even light.
If you venture too close and cross the so-called event horizon, the point from which no light can escape, you will also be trapped or destroyed.
For small black holes, you would never survive such a close approach anyway.
The tidal forces close to the event horizon are enough to stretch any matter until it's just a string of atoms, in a process physicists call 'spaghettification'.
But for large black holes, like the supermassive objects at the cores of galaxies like the Milky Way, which weigh tens of millions if not billions of times the mass of a star, crossing the event horizon would be uneventful.
Because it should be possible to survive the transition from our world to the black hole world, physicists and mathematicians have long wondered what that world would look like.
They have turned to Einstein's equations of general relativity to predict the world inside a black hole.
These equations work well until an observer reaches the centre or singularity, where, in theoretical calculations, the curvature of space-time becomes infinite.
Exoplanet KOI-3010.01 is considered habitable with a probability of 84% – Highest EVER
Exoplanet KOI-3010.01 is considered habitable with a probability of 84% – Highest EVER
The transit method was used by the Kepler mission to find a planet that circles the star KOI-3010. Researchers are interested in this world because it is similar to Earth in some ways.
The red dwarf KOI-3010 is 1213 light-years away from us in the constellation Lyra. This star is very old. It could be as old as 13.9 billion years. Planet KOI-3010.01, also called KOI-3010 b, is a warm super earth (it is more than Earth on a mass, but it is much inferior to gas giants). A trip around the star takes about 60 days on Earth.

Environmental factors play a role in how life started and how it has grown on Earth. Its average temperature is 19.6 degrees Celsius. It is 1.35 times the size of Earth. They don’t know much about the atmosphere, but it’s there (there is an assumption that it is almost identical to the earth). The mass index has not been worked out yet. Scientists think that the exoplanet KOI-3010.01 will have a temperate climate like Earth and an ocean that covers about 65% of its surface.
Exoplanet KOI-3010.01 was found to be habitable with an 84% probability (extremely high)
KOI-3010.01 is about 1.78 times larger and 2 times heavier than the Earth and completes a revolution around the parent star in 60.87 days. The exoplanet fits perfectly into the habitable zone.

Scientists think that the chemical makeup of exoplanets is very similar to that of Earth. It is important to note that it is in the habitable zone and has an index of 0.84, which means that it is most like Earth (maximum – 1). Researchers think she has a good chance of living because of this.
Zwart gat verorbert ster op 8,5 miljard lichtjaar van hier en spuwt lichtstraal uit zo helder als 1.000 biljoen zonnen
Dat astronomen getuigen zijn van een superzwaar zwart gat dat een ster verorbert, is zeldzaam. In februari bleek dit spectaculaire kosmische fenomeen zich te hebben afgespeeld op 8,5 miljard lichtjaar van onze planeet. De lichtstraal die met die maaltijd gepaard ging, had een intensiteit van maar liefst 1.000 biljoen zonnen.
Op 11 februari spotte de telescoop van de Zwicky Transient Facility in Californië een atypische, heldere flits in de lucht. De lichtflits, AT 2022cmc genaamd, was anders dan die astronomen doorgaans waarnemen. Het licht leek zelfs sterker dan 1.000 biljoen zonnen samen en kwam van 8,5 miljard lichtjaar ver. Getallen die écht doen duizelen en voor ons brein eigenlijk niet te vatten zijn.
Toch een poging. Een lichtjaar is de afstand die het licht in een jaar aflegt. Als je weet dat licht met ruim een miljard kilometer per uur reist, dan weet je ook dat een afstand van 8,5 miljard lichtjaar énorm ver weg is van onze aarde, meer dan halfweg het universum. En die duizendbiljoen, dat is dan weer een ‘1' met vijftien nullen. Héél veel zonnen dus.
Astronomen van over de hele wereld waren gefascineerd en er werden nog zo’n twintig andere telescopen ingezet. Het onderzoek naar de spectaculaire ontdekking leidde tot twee artikels die deze week gelijktijdig verschenen in de wetenschappelijke tijdschriften Nature en Nature Astronomy. Hun conclusie is dat het opgepikte signaal voortkwam uit een unieke, extreme “getijdenverstoring” (TDE of tidal disruption event in het Engels). Dat is een kosmisch fenomeen waarbij een ster zo dicht bij een superzwaar zwart gat komt, dat het door de door de getijdenkrachten van het zwarte gat wordt verscheurd.
Dat gebeurt nog: de vorige waarneming is beschreven in 2012. Heel af en toe - in ongeveer 1 procent van de gevallen - gaan zwarte gaten zodanig fel tekeer tijdens hun maaltijd dat de ster aan flarden gaat nog voor ze helemaal en definitief verdwijnt. De enorme zwaartekracht kan dan stukken van dat materiaal met bijna de lichtsnelheid in de ruimte slingeren. De Amerikaanse astronoom John Wheeler vergeleek het met een tube tandpasta die je heel hard in het midden vastknijpt, zodat aan beide kanten van de tube tandpasta wegschiet. Mutatis mutandis gebeuren die uitbarstingen dan aan de polen van het zwarte gat.
Als de wetenschappers het bij het rechte eind hebben, dan gaat het ditmaal om de verste TDE van de vier soortgelijke met zo’n snelle straal die tot nu toe werden gespot. Maar nog straffer was de intensiteit van de lichtflits die van materie uit de binnenkant van het superzware gat stroomde en met een supersonische snelheid reisde. De extreme helderheid kan enkel worden verklaard als de TDE ook rechtstreeks naar ons wees. Omdat het licht van AT 2022cmc op ons afkomt, wordt het niet minder fel naarmate het vordert. Integendeel, de straal wordt alsmaar helderder, nog meer door de enorme kracht waarmee ze uitgespuwd wordt en waardoor ze de lichtsnelheid benadert. Dat effect heet ‘Doppler-boosting’ en is vergelijkbaar met het geluid van passerende sirenes dat sterker wordt als het nadert.

The tiny 14 kg (30 lb) spacecraft will use near-infrared lasers and an onboard spectrometer to map the permanently shadowed regions near the Moon’s south pole, where there could be reservoirs of water ice.
“If we are going to have humans on the Moon,” said Barbara Cohen, Lunar Flashlight principal investigator, “they will need water for drinking, breathing, and rocket fuel. But it’s much cheaper to live off the land than to bring all that water with you.”

Several previous missions have found evidence of water ice at the Moon’s poles, including Lunar Prospector, the Lunar Crater Observation and Sensing Satellite (LCROSS) and the Lunar Reconnaissance Orbiter. Additionally, other observations have provided many lines of evidence for deep water ice deposits the permanently shadowed regions across both lunar poles.
Cohen told Universe Today that Lunar Flashlight will be looking for “operationally useful” quantities of ice, meaning enough water ice within the craters or embedded in the regolith that could be easily extracted by future rovers or lunar explorers.

Lunar Flashlight has just one instrument, a four-laser reflectometer that uses a low-power infrared beam to illuminate the permanently shadowed regions in polar craters. The spectrometer can distinguish between dry regolith and water ice, as the light reflected back from the lunar surface will allow the spacecraft to detect water ice absorption bands in the near infrared.
“Infrared wavelengths are absorbed by water,” Cohen explained, “so if water ice there, we’ll get fewer photons back than we what we sent.”
By repeating these measurements over multiple points and across multiple orbits, the Lunar Flashlight team will be able to create a map of surficial ice concentration. This method could allow NASA to not only find reservoirs of ice but potentially figure out how large they are, since more absorption could indicate more water. Cohen said the data they get can be correlated with data from previous missions to help guide future rovers and humans where to find the water ice.
That’s a big task for such a small spacecraft, and Cohen said having such a small footprint to work with was a challenge in constructing the spacecraft.
“Having a 14-kilogram spacecraft means you have to shrink a lot of things down,” Cohen said. “But it also means you must get innovative about what you’re including and what you’re not. That means we could only have one instrument, as we didn’t have room for more. But it’s a great instrument and it’s the first time that active laser spectroscopy will be done at the Moon.”
They also had to make their spacecraft require very low power, as there isn’t room for a lot of batteries.
“Our lasers have the intensity similar to that of a laser pointer,” Cohen explained. “Such low power means we need to be very close to the lunar surface, about 15-20 kilometers away.”
Even a full size satellite with a lot of fuel would have a hard time maintaining a that low of an orbit, so Lunar Flashlight will use an innovative orbit called a near rectilinear halo orbit. This is the same orbit currently being used by the microwave-oven-sized CAPSTONE (Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment), which is conduct tests to make sure this unique lunar orbit is actually stable. The same orbit has been proposed for the NASA’s future Lunar Gateway. This near-rectilinear halo orbit will take it 70,000 km (42,000 miles) from the Moon at its most distant point and, at its closest approach, the satellite will graze the surface of the Moon, coming within 15 km (9 miles) above the lunar South Pole.
“This orbit enables us to come very, very close to the surface when we want to make the measurements and then go very far away as an energy saving measure for the rest of the orbit,” Cohen said, adding that her team is definitely keeping an eye on how things are going for CAPSTONE.
For the primary mission, Lunar Flashlight will get approximately 10 passes of the Moon, depending on how much fuel they have.
“We have an eight-month primary mission, but it depends on fuel,” Cohen said. Roughly 50 minutes after launch, Lunar Flashlight will eject from the second stage of the Falcon 9 rocket. “When we are ejected, the spacecraft will tumble and we need to use fuel to get into the right orbit. With such a small fuel tank, we don’t have a huge amount of margin.”
Lunar Flashlight is considered a technology demonstration mission, as it is testing out several technological firsts, including the first use of the laser reflectometer to look for water ice and the first planetary CubeSat mission to use “green” propulsion – a propellant that is less toxic and safer than hydrazine, a common propellant used by spacecraft.
Another unique aspect is that the “mission control” for the spacecraft is housed at Georgia Tech and will be staffed by a group of 14 operators — eight graduate students and six undergraduates.
“These students helped put this spacecraft together, they wrote all the scripts, they’ll be doing the uplink and downlink – they’re the ones actually in control of the spacecraft. It’s been really gratifying to see such a really meaningful level of student involvement, and they’re going to know the ins and out of operating a spacecraft. You just know those students are going to go on to have amazing careers.”
There have been a few delays leading up to the launch of Lunar Flashlight and Japan’s Hakuto-R Mission, but the launch time is now set for Thursday, December 1 at 3:37 a.m. ET from Cape Canaveral Space Force Station in Florida.
Wormhole is created inside a quantum computer that 'teleported' a message from one side to the other - and this could help scientists observe the theorized passages in real space
Wormhole is created inside a quantum computer that 'teleported' a message from one side to the other - and this could help scientists observe the theorized passages in real space
Wormholes are theorized passages that create shortcuts in space-time
It would be a 'tunnel' that connects two distant points, allowing things to travel in a shorter time
Scientists created a 'holographic' wormhole inside of a quantum computer
The team made it by simulating two black holes in the system, one on each side
They sent a message through one side and watched it emerge on the other
The first-ever wormhole, a theoretical passage that creates shortcuts in space-time, has been created inside of a quantum computer in a breakthrough that could lead to the first observation of one in space.
While this tunnel is not through actual space, scientists made it by simulating two black holes in the system, one on each side, and used it to 'teleport' messages.
The holographic wormhole will be the first time scientists can analyze how the passage would work since the idea was proposed nearly 100 years ago.
Daniel Jafferis of Harvard and co-author of the study said that the innovation is not a hologram that can be seen but is 'a filament of real space-time.'
A wormhole is a theorized passage that creates a shortcut in space-time, the 3-D 'fabric' that makes up space, which can be warped and distorted. Scientists created one in a quantum computer
A wormhole is a type of bridge that could form when space-time is folded. Space-time is the 3-D 'fabric' that makes up space, which can be warped and distorted.
The passage is described as a structure that connects two distant parts in spacetime, acting as a shortcut from one to the other. And the points can be billions of light-years away.
While Albert Einstein and physicist Nathan Rosen are known for proposing the theory dubbed Einstein-Rosen bridges in 1935, the idea was first shared in 1928 by German mathematician Hermann Weyl.
Weyl, however, referred to it as 'one-dimensional tubes.'
Physicist John Wheeler was the first to call it 'wormhole' in the 1950s.
Maria Spiropulu at the California Institute of Technology and her colleagues used Google’s Sycamore quantum computer to simulate a holographic wormhole.
While an actual wormhole would be powered through gravity, the holographic creation used quantum effects, New Scientist reports.
Scientists made it by simulating two black holes in the system, one on each side, and used it to 'teleport' messages
The team used a qubit - the quantum equivalent of a bit in conventional silicon-based computers - and observed it travel to the next system.
The qubit moved through quantum teleportation, a process by which information about quantum states can be sent between two distant but quantum entangled particles.
The particles interact and share their physical states for an instant - no matter how far the distance separates them.
Alexander Zlokapa, a former undergraduate student at Caltech who started on this project for his bachelor's thesis, said in a statement: 'We performed a kind of quantum teleportation equivalent to a traversable wormhole in the gravity picture.
'To do this, we had to simplify the quantum system to the smallest example that preserves gravitational characteristics so we could implement it on the Sycamore quantum processor at Google.'
The physicists report that wormhole behavior acted as expected from both gravity and quantum physics perspectives.
'The relationship between quantum entanglement, spacetime, and quantum gravity is one of the most important questions in fundamental physics and an active area of theoretical research,' Spiropulu said.
'We are excited to take this small step toward testing these ideas on quantum hardware and will keep going.'
WHAT ARE WORMHOLES AND COULD THEY TRANSPORT US ACROSS THE UNIVERSE?
Space-time can be warped and distorted, although It takes an enormous amount of matter or energy to create such distortions.
In the case of the wormhole, a shortcut is made by warping the fabric of space-time.
Imagine folding a piece of paper with two pencil marks drawn on it to represent two points in space-time.
Space-time can be warped and distorted, although It takes an enormous amount of matter or energy to create such distortions. In the case of the wormhole (artist's impression), a shortcut is made by warping the fabric of space-time
The line between them shows the distance from one point to the other in normal space-time.
If the paper is now bent and folded over almost double - the equivalent to warping space-time - then poking the pencil through the paper provides a much shorter way of linking the two points, in the same way a wormhole would create a shortcut.
The problem with using wormholes to travel in space or time is that they are inherently unstable.
When a particle enters a wormhole, it also creates fluctuations that cause the structure to collapse in on it.
However, some studies have claimed that travelling through these theoretical shortcuts might be possible - in spite of the extreme forces at play.
They could be used to traverse distances from a few metres, across lightyears or even to entirely new universes, some say.
Scientists Send Quantum Data Through a Simulated Wormhole
For the first time, scientists have created a quantum computing experiment for studying the dynamics of wormholes — that is, shortcuts through spacetime that could get around relativity’s cosmic speed limits.
“We found a quantum system that exhibits key properties of a gravitational wormhole, yet is sufficiently small to implement on today’s quantum hardware,” Caltech physicist Maria Spiropulu said in a news release. Spiropulu, the Nature paper’s senior author, is the principal investigator for a federally funded research program known as Quantum Communication Channels for Fundamental Physics.
Don’t pack your bags for Alpha Centauri just yet: This wormhole simulation is nothing more than a simulation, analogous to a computer-generated black hole or supernova. And physicists still don’t see any conditions under which a traversable wormhole could actually be created. Someone would have to create negative energy first.
Columbia theoretical physicist Peter Woit warned against making too much of a to-do over the research.
“The claim that ‘Physicists Create a Wormhole’ is just complete bullshit, with the huge campaign to mislead the public about this a disgrace, highly unhelpful for the credibility of physics research in particular and science in general,” he wrote on his blog, which is called Not Even Wrong.
The main aim of the research was to shed light on a concept known as quantum gravity, which seeks to unify the theories of general relativity and quantum mechanics. Those two theories have done an excellent job of explaining how gravity works and how the subatomic world is structured, respectively, but they don’t match up well with each other.
One of the big questions focuses on whether wormhole teleportation might follow the principles that are behind quantum entanglement. That quantum phenomenon is better understood, and it’s even been demonstrated in the real world, thanks to Nobel-winning research: It involves linking subatomic particles or other quantum systems in a way that allows for what Albert Einstein called “spooky action at a distance.”
Spiropulu and her colleagues, including principal authors Daniel Jafferis and Alexander Zlokapa, created a computer model that applies the physics of quantum entanglement to wormhole dynamics. Their program was based on a theoretical framework known as the Sachdev-Ye-Kitaev model, or SYK.
The big challenge was that the program had to be executed on a quantum computer. Google’s Sycamore quantum processing chip was just powerful enough to take on the task, with an assist from conventional machine learning tools.
“We employed [machine] learning techniques to find and prepare a simple SYK-like quantum system that could be encoded in the current quantum architectures and that would preserve the gravitational properties,” Spiropulu said. “In other words, we simplified the microscopic description of the SYK quantum system and studied the resulting effective model that we found on the quantum processor.”
The researchers inserted a quantum bit, or qubit, of encoded information into one of two entangled systems — and then watched the information emerge from the other system. From their perspective, it was as if the qubit passed between black holes through a wormhole.
“It took a really long time to arrive at the results, and we surprised ourselves with the outcome,” said Caltech researcher Samantha Davis, one of the study’s co-authors.
The team found that the wormhole simulation allowed information to flow from one system to the other when the computerized equivalent of negative energy was applied, but not when positive energy was applied instead. That matches what theorists would expect from a real-world wormhole.
As quantum circuits become more complex, the researchers aim to conduct higher-fidelity simulations of wormhole behavior — which could lead to new twists in fundamental theories.
“The relationship between quantum entanglement, spacetime, and quantum gravity is one of the most important questions in fundamental physics and an active area of theoretical research,” Spiropulu said. “We are excited to take this small step toward testing these ideas on quantum hardware and will keep going.”
In addition to Jafferis, Zlokapa, Spiropulu and Davis, the authors of the Nature paper, titled “Traversable Wormhole Dynamics on a Quantum Processor,” include Joseph Lykken, David Kolchmeyer, Nikolai Lauk and Hartmut Neven.
Unknown space object (meteorite?) plunges into the sea near the Canary Islands
Unknown space object (meteorite?) plunges into the sea near the Canary Islands
Translation from report diariodeavisos.elespanol.com: A possible meteorite has triggered the alarms in Gran Canaria on the afternoon of this Wednesday. According to official sources, it crossed La Palma, El Hierro, La Gomera, the south of Tenerife and passed through Gran Canaria, to end up plunging into the sea, on the north coast, between the municipalities of Arucas and Guía.
The loud noise generated by the trajectory of the meteorite triggered alarm among the population in different parts of the island, with special emphasis on the Santa Brígida area, where it was even thought of a landslide. The subsequent fire in an area of the municipality suggested that it was due to the impact of the meteorite, something that was later ruled out.
When it entered the Canarian sky, a luminous object of an intense red color was seen and then a trail of smoke. He crossed the western islands in the direction of Gran Canaria.
The alert began at 3:39 p.m. this Wednesday, at which time dozens of people have called 112 reporting "tremors" of origin yet to be identified. According to the sources of the emergency service, they have not had to intervene for the moment and are collecting information about the incident.
"I do not know the origin, but the tremor was quite important. Not only windows, the floor and walls trembled and in the background a sound like a distant explosion," said Twitter user @meteograncanaria.com
The National Geographic Institute has registered the shock, but still does not specify the origin. The authorities are trying to find out the cause of the great noise that this Wednesday keeps Gran Canaria in suspense .
Although it is believed to have been a meteorite, this has not yet been proven. It is said to have been a 3-foot-long object that would weigh many tons. Such an object would cause a huge tidal wave when it crashes into the sea and that does not seem to be the case here. So, was it a meteorite or could it have been something else that crashed into the sea?
Twitter page below: The great roar this afternoon in Gran Canaria was not produced by any earthquake. At our seismic stations we see the noise of some kind of unknown explosion. What we see is sound. Therefore, this is outside of our competences

Massive, Unidentified Object 75 Miles Wide Detected By Scientists At NASA
Massive, Unidentified Object 75 Miles Wide Just Detected By Scientists At NASA. Recently, astronomers spotted a massive, 75 miles wide strange object approaching the outer regions of our solar system. The discovery soon caused ripples of excitement and curiosity within the planetary science community because the object is of an unusually large size and of an abnormal origin. The object is approaching our Solar System from the Oort Cloud, a huge region surrounding the Sun that starts far, far beyond the orbit of Neptune, where no manmade object has been able to get at properly, yet. Studying the mysterious object could change everything for astronomers and astronomy, to say the very least. This is the shocking discovery that was made by NASA of an unidentified object entering our solar system.

A slice of the El Ali meteorite contains two minerals never seen before in a natural state on Earth.Photograph: Supplied
A team of researchers in Canada say they have discovered two new minerals – and potentially a third – after analysing a slice of a 15-tonne meteorite that landed in east Africa.
The meteorite, the ninth largest recorded at over 2 metres wide, was unearthed in Somalia in 2020, although local camel herders say it was well known to them for generations and named Nightfall in their songs and poems.
Western scientists, however, dubbed the extraterrestrial rock El Ali because it was found near the town of El Ali, in the Hiiraan region. A 70-gram slice of the iron-based meteorite was sent to the University of Alberta’s meteorite collection for classification.

Dr Chris Herd, a professor in the department of earth and atmospheric sciences and the curator of the collection, said that while he was classifying the rock he noticed “unusual” minerals. Herd asked Andrew Locock, the head of the university’s electron microprobe laboratory, to investigate.
“The very first day he did some analyses, he said, ‘You’ve got at least two new minerals in there’,” said Herd. “That was phenomenal. Most of the time it takes a lot more work than that to say there’s a new mineral.”
Similar minerals had been synthetically created in a lab in the 1980s but never recorded as appearing in nature, Herd said, adding that these new minerals could help understand how “nature’s laboratory” works and may have as yet unknown real-world uses. A third potentially new mineral is being analysed.

“I never thought I’d be involved in describing brand new minerals just by virtue of working on a meteorite,” said Herd. “That’s what makes this exciting: in this particular meteorite you have two officially described minerals that are new to science.” They have been named elaliite, after the location of the meteorite, and elkinstantonite, after Lindy Elkins-Tanton, principal investigator of Nasa’s upcoming Psyche mission that aims to send a spacecraft to a metal-rich asteroid.
“Lindy has done a lot of work on how the cores of planets form, how these iron nickel cores form, and the closest analogue we have are iron meteorites. So it made sense to name a mineral after her and recognise her contributions to science,” Herd said.
University of Alberta scientists would like to examine other samples from the same meteorite but Herd said there were reports that it had been removed to China. Meteorites are often bought and sold on international markets.
A third ancient human skull has been uncovered at a site in China. A 3D reconstruction of the second skull, discovered three decades ago and called Yunxian 2, is pictured.

Researchers are heralding the discovery of an ancient human skull in central China as an important find. As excavation of the remarkably intact fossil continues, archaeologists and palaeoanthropologists anticipate that the skull could give a fuller picture of the diverse family tree of archaic humans living throughout Eurasia in prehistoric times.
Archaeologists expect to finish excavating the ancient human skull in November, at the same site in Yun county, Hubei province in central China where the remains of two other million-year-old humans were found decades ago.

The skull was discovered on 18 May at an excavation site 20 kilometres west of Yunyang — formerly known as Yunxian — in central China’s Hubei province. It lies 35 metres from where two skulls — dubbed the Yunxian Man skulls — were unearthed in 1989 and 19901, and probably belongs to the same species of ancient people, say researchers.
“It’s a wonderful discovery,” says palaeoanthropologist Amélie Vialet at the National Museum of Natural History in Paris, who has worked on the first two skulls, commonly referred to as Yunxian 1 and 2. Unlike those earlier discoveries, which were crushed and distorted after millennia underground, the third skull, Yunxian 3, seems to be in good condition.
In 2010, Vialet and her colleagues created digital reconstructions of the Yunxian 2 skull, and confirmed that it was probably a member of the archaic human species Homo erectus2. Dating of sediment and animal fossils from the site suggest that the Yunxian humans lived between 1.1 million and 800,000 years ago.
Is Yunxian Man Homo erectus?
Homo erectus was first described from fossils found on the Indonesian island of Java in the late nineteenth century. Javanese fossils dating to 1.5 million years ago suggest that members of the species might have been the first early humans to have ventured out of Africa.
Homo erectus was both widespread and long-lived. Remains have been found in eastern Africa, eastern Asia and possibly Europe, and they span a period from 1.9 million to 250,000 years ago. Because of this, there is a great deal of variability in the species’ fossil record, and the precise relationships between different populations are a matter of debate

The Yunxian 3 skull is half-buried in an upright position. Researchers have uncovered the forehead, including the brow ridge and eye sockets, as well as the top, back and left cheekbone of the skull. It is not yet known whether teeth or a lower jawbone are attached to the skull, says Gao Xing at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, who is leading the excavation.
Vialet says that the Yunxian 1 and 2 skulls share some features with older Javanese fossils, and others with younger Homo erectus fossils from mainland Asia. Like the Javanese fossils, they are large, big-brained skulls. But she says that they are less heavily built, a characteristic that usually indicates a more modern individual.
Researchers have found Homo erectus remains at more than a dozen sites across China. Vialet says that the ancient humans at Yunxian could be the ancestors of some of these populations, but their skulls bear distinct features that set them apart.
For example, fossils from around 700,000 years ago that were discovered in the Zhoukoudian cave system in suburban Beijing — known as the Peking Man Site — have a prominent sagittal keel, a crest that runs along the midline of the skull for the attachment of strong jaw muscles. The Yunxian skulls all seem to lack this feature, says Vialet.
Variable fossils
Yameng Zhang, a palaeoanthropologist at Shandong University, says that the Homo erectus fossils found in China are highly variable and researchers don’t know why. It could be that each population evolved independently in Asia. Or they could have been the result of multiple waves of expansion out of Africa, he says. “More complete Chinese H. erectus like Yunxian 3 are crucial to answer this question.”
Vialet says that the Yunxian 3 skull should be compared with Chinese as well as European hominin fossils, such as the 1.4-million-year-old face from the Sima del Elefante cave in Atapuerca, Spain, discovered in July. She is currently comparing Yunxian 2 with European hominin fossils, and says that the Yunxian people could be more similar to European populations from the middle Pleistocene epoch than they are to later specimens from China.
If the Yunxian 3 skull has teeth, especially molars, they could be useful for discerning evolutionary relationships with other early humans, says Clément Zanolli at the University of Bordeaux, France.

An age-old question
Once the Yunxian 3 skull is excavated, probably within the next few months, dating it will be an important task. Several techniques have been used to estimate the age of Yunxian 1 and Yunxian 2 at between 800,000 and 1.1 million years.
Wei Wang, a geochronologist at Shandong University, says that hominin fossils in China are often more difficult to date than fossils in Africa, because China lacks volcanic sediments that can be reliably dated by measuring the amounts of radioactive isotopes in the rock.
Jean-Jacques Bahain at the National Museum of Natural History in Paris dated sediments collected from the Yunxian site using electron spin resonance and uranium series dating3. This requires a close comparison between values taken from the fossil and the quartz in the sediment. But he says that the samples he measured weren’t collected at the same time and location as the Yunxian 1 and 2 skulls.
The discovery of Yunxian 3 therefore represents a unique opportunity to collect sediment samples from the ground that the skull sits in, he says.
Small animal fossils surrounding the Yunxian 3 skull are slowing the extraction process, according to Gao. Bahain says that such specimens could help to pinpoint the age of the Yunxian 3 skull, and also connect it to early human remains elsewhere in China that have been found with prehistoric fauna.
