James Webb Found Universe Breakers. Is The Big Bang WRONG?

[00:00:00]The night sky isn’t what you think it is. It’s not the beginning of time… it’s a graveyard of light. The James Webb Space Telescope just sent back images of thermal 'bruises' in deep space.  Physical scars left behind by a universe that died before ours was even born. The data doesn't just  tweak the laws of physics... it sets them on fire.

[00:00:19]And NASA is panicking. University of Kansas astronomer Allison Kirkpatrick couldn't sleep. She had spent  her professional career studying how galaxies grow and evolve. But the first images from the  James Webb Space Telescope, orJWST, left her questioning everything she thought she knew. JWST is the most advanced and powerful space telescope ever built. It was going to  give astronomers and scientists a glimpse into the past. A hint about how the first  galaxies formed. Instead, it showed bright, fully formed galaxies where there should have  been darkness. They appeared in regions of the universe that should have been practically empty. Back then, the cosmos was supposed to be a thin fog of hydrogen and helium, slowly cooling  and drifting, waiting for gravity to do its work. But these images… they didn’t make sense.  That primordial fog was expected to last for hundreds of millions of years. Just floating  in space. Long before any stars were born.

[00:01:14]And those first celestial bodies should  have burned out quickly and scattered the ingredients for everything that followed. So the early universe, in theory, should have been a blank canvas. JWST said differently.

[00:01:26]The common assumption was that the universe  followed one model: Lambda CDM. It’s the standard story of the cosmos. A hot Big Bang,  invisible dark matter pulling gas into clumps, and dark energy driving everything apart faster  and faster. For years, the data backed it up. The universe was 13.8 billion years old. Or so we thought.

[00:01:46]The first full color Webb image landed  in July 2022, showing a galaxy cluster called SMACS 0723. Immediately, something was  wrong. There were too many galaxies. They were too bright. They shouldn’t have been there.  Research papers were thrown out, consigned to trash cans. If the images were accurate,  then the timeline of early galaxies was wrong.

[00:02:09]The old galaxy consensus was dead. A faint smudge in the Boötes constellation was the prime suspect. Its  catalog name is CEERS-93316 and its first measurement suggested it was seen at a redshift  of 16.7. It was a number that raised eyebrows.

[00:02:28]Redshift is essentially a time machine  built into the fabric of the universe.

[00:02:32]As space expands, it stretches the light traveling  through it, pulling it toward the red end of the spectrum. The more stretched that light is, the  further back in time it comes from. Eventually, looking deeper into redshift feels  less like looking farther away, and more like watching earlier and earlier  versions of the universe play out in reverse.

[00:02:51]At a redshift of 16.7, this object would  sit about 235 million years after the Big Bang. It’s an era where almost nothing  this large should have had time to form.

[00:03:02]Think of the entire universe as a huge building  site. A crew has just broken ground on an empty lot. Five minutes later, you take a photo,  and in the middle of the lot is a finished 100 story tower. The lights are on and a hive  of activity. There hasn’t been enough time to build something like this. And yet… there it is.

[00:03:20]In JWST’s near-infrared images, the galaxy  looked exactly like that kind of anomaly.

[00:03:26]For a moment, it fit the profile of  something from the early universe.

[00:03:30]Then that argument began to fall apart. That 16.7 was a quick estimate, pulled from the galaxy’s color across a handful of broad filters.  It was more of a first guess than a verdict.

[00:03:41]So the team went back and ran it through JWST’s  spectrograph, an instrument that reads light in detail. The result changed everything. The extreme  distance disappeared. The true redshift was 4.9, an ordinary galaxy, about 1.2 billion years old. What had looked like a cosmic record-breaker turned out to be a trick of alignment. At just  the right distance, a hydrogen emission line slid neatly into 3 of the reddest filters, while  a set of oxygen lines boosted a 4. It lit up in a handful of bands, went dark in the rest, and  mimicked something far older than it really was.

[00:04:15]The most distant object ever seen was a mirage. But not every galaxy collapsed under closer scrutiny. Some held up completely. By 2024, dozens  of early galaxies had been checked, and most were where their first color estimates suggested. Only  a few, like the Boötes smudge, turned out to be impostors. The real early galaxies tend to be  smaller and dimmer, but they survived every test.

[00:04:39]So the early universe isn’t an illusion. It’s  just harder to read than it first appears.

[00:04:44]But one problem still refuses to go away. And it’s worse than anyone thought.

[00:04:49]Adam Riess, a Nobel Prize winner, studies how  fast the universe is expanding right now. His team builds what’s called a cosmic distance  ladder. It’s a way of measuring across space using known, repeating cosmic signals  as stepping stones. And it’s caused a problem scientists now call the Hubble Tension. Riess and his team used their model and arrived at a number, 73. But there’s another way to read  the universe. Instead of looking at nearby space, it starts with the oldest light we can see: a  faint afterglow from when the universe was just 380,000 years old. It’s a frozen snapshot of the  early cosmos, before stars and galaxies existed.

[00:05:26]If you take that starting point and run the  universe forward using the standard model, you don’t get 73. You get about 67. Those two numbers should match.

[00:05:37]They don't. The gap between them has now reached what scientists call 5 sigma. It’s  a way of saying the difference is so large that, if nothing is wrong, it would almost never  appear by chance. In practical terms, it’s about 1 in 3.5 million. That's almost 3  times rarer than getting struck by lightning.

[00:05:54]At first, people assumed it had to be an error  in the cosmic ladder. But JWST looked again.

[00:06:00]There was no error. Riess used JWST to recheck over 1,000 of his stars. The  distances barely moved. His ladder held.

[00:06:09]Not everyone agrees on where the problem lies. Wendy Freedman, an astronomer at the University of Chicago, approached the question using  a completely different method. Instead of relying on the same cosmic distance ladder,  she used a special class of red giant stars as guides. Her result came in around 70,  right between the two competing answers.

[00:06:27]That matters because it suggests the Hubble  Tension might not be as simple as one side being right and the other wrong. The trouble is that no explanation has managed to satisfy everyone. One of the leading ideas is something called early dark energy, a brief burst  of extra energy that may have altered the universe’s expansion shortly after the Big Bang.  If something like that happened, it could help explain the conflicting measurements. Projects  such as the Dark Energy Spectroscopic Instrument, or DESI, is surveying tens of millions of  galaxies, searching for evidence that the universe once expanded differently than we think. Maybe one set of measurements still contains a hidden flaw. Maybe dark energy has changed  over time. Or maybe the standard model of the universe is missing a piece entirely. What makes the Hubble Tension so unsettling is that it goes beyond the usual explanation.  Earlier anomalies often faded under a closer look. A galaxy that seemed distant turned out  to be closer. A strange signal turned out to be misleading. The mystery shrunk. This one didn't.

[00:07:27]It’s a difference between the universe we  see today and the universe our best model predicts. The more precisely anyone measures  it, the harder that difference becomes to In 2023, Ivo Labbé and his team published a  paper highlighting 6 objects that shouldn’t have existed. We’re seeing them 500 to  700 million years after the Big Bang, when the universe was still in its infancy. Yet  they already looked like fully grown galaxies.

[00:07:52]The problem was their size. By some estimates, they had 10 to 100 times more mass than models said was possible. A  few appeared to rival 100 billion Suns, all packed into regions smaller than the Milky Way. If those first measurements were right, astronomers had a serious problem. There simply  hadn't been enough time for these galaxies to build that many stars. The numbers didn't add up. So the investigation started over. And as better data came in, the impossible began to shrink. Astronomers called them little red dots.

[00:08:23]JWST wasn't finding just one or two. It was  spotting them everywhere it looked. When researchers studied their light more closely,  they noticed something strange. Instead of the clean signature you'd expect from a normal galaxy,  the light showed wide, smeared emission lines. It was a telltale sign that gas was whipping  around a black hole at incredible speeds.

[00:08:43]That changed everything A lot of these objects seem to hide black holes weighing millions - or even hundreds  of millions - of Suns behind thick clouds of dust.

[00:08:53]That's important. Black holes can be unbelievably  bright. Bright enough to fool us into thinking we're seeing far more stars than are really there. One of the earliest candidates looked almost as big as the Milky Way. Our galaxy took more  than 13 billion years to build up that much mass. This object seemed to have done  it in just a few hundred million years.

[00:09:12]That's what made astronomers wonder if they  were looking at something else entirely.

[00:09:16]One possibility is something called a black hole  star: a black hole buried inside a thick cocoon of gas. From billions of light-years away, it can  look like a single enormous star. If they exist, JWST might just have found the first one. But there's still a problem.

[00:09:32]The early universe didn't have  that much material to work with.

[00:09:36]Most of the ordinary matter was still floating  around as gas, not locked up in stars.

[00:09:41]To get that massive so quickly, these galaxies  would have had to pull off something never seen before. Almost every bit of available gas  would need to become stars. Then it would have to squeeze into one small space It seemed impossible.

[00:09:54]But there was another issue. Some of these little red dots are surprisingly faint in X-rays. Active black  holes usually shine brightly in X-rays. It just added to the mystery. Some of the little red dots  could be dust-shrouded black holes. Some could be something else completely. But the idea that  these were massive galaxies was fading fast.

[00:10:13]It’s more like that astronomers  were counting the wrong light.

[00:10:17]But what if the galaxies aren't the problem? Physicist Rajendra Gupta proposed a much more radical answer. Maybe those galaxies  only look old because the universe itself is older than we think. His model, called CCC+TL, moves the age of the universe from 13.8  billion years to roughly 26.7 billion.

[00:10:36]That would give the cosmos almost twice as much  time to build galaxies, stars, and black holes.

[00:10:42]Suddenly those early galaxies  don't look so impossible.

[00:10:45]To get there, Gupta combined two controversial  ideas. The first allowed some of nature's fundamental constants to slowly change over time.  The second updates a theory called tired light.

[00:10:56]This is where photons gradually lose energy  as they travel across the universe. Distant galaxies look redder not because space expanded,  but because their light faded during the journey.

[00:11:06]It sounds plausible. But most physicists aren't convinced.

[00:11:10]Gupta published the idea in a peer-reviewed  journal in 2023, and other researchers quickly responded. Their argument was simple: the  model clashes with too much existing evidence.

[00:11:19]It struggles to address the cosmic microwave  background, the leftover glow of the Big Bang.

[00:11:25]There's a bigger issue. The trouble is that tired light has been around for a long time. And every  time astronomers have put it to the test, it comes up short. If the universe is expanding,  distant galaxies should look redder, dimmer, and stretched in specific ways. That's  exactly what we see. Tired light can explain the reddening, but it doesn’t explain rest. So while it's a good attempt to solve the mystery, most astronomers don't think it's the answer. But what if the issue was the big bang?

[00:11:52]If anyone gets to propose a radical idea about  the universe, it's Roger Penrose. He's one of the world's leading experts on black holes and  won a Nobel Prize for his work. His idea is called Conformal Cyclic Cosmology, or CCC. And it starts with a simple question: what if the Big Bang wasn't the beginning? According to Penrose, the universe goes through endless cycles. One age ends, another  begins. It’s a cycle that goes on and one.

[00:12:16]Imagine fast-forwarding trillions upon  trillions of years into the future.

[00:12:20]Every star has burned out and matter has decayed.  Even the last black holes have evaporated away.

[00:12:26]Everything is gone. Penrose argues that at that point, the difference between infinitely large and  infinitely small starts to lose its meaning.

[00:12:34]And if that's true, the end of one universe  could become the beginning of the next.

[00:12:38]In other words, the Big Bang might not have been  a beginning at all. It could have been the end of a universe that existed before ours. Penrose has even gone a step further.

[00:12:48]He proposed a hypothetical dark matter particle  called an erebon. If these particles exist, they could leave faint traces in the sky  that future telescopes might be able to spot.

[00:12:58]But there's a catch. For this to work, the future  of the universe has to behave in ways we've never observed. That's why most cosmologists see CCC  as an interesting possibility rather than a definitive explanation. It's a bold idea.

[00:13:12]The question is whether nature agrees. Penrose claims his theory can be tested.

[00:13:17]He believes his cyclic universe left real  evidence and we’ve already captured it.

[00:13:22]According to his theory, the universe before  ours contained enormous black holes. Over time, those black holes evaporated away. In  Penrose's model, the final burst of energy from each one crossed the boundary between  cosmic cycles and left an imprint on our universe.

[00:13:38]A fingerprint of a dead universe. Where would you look for that fingerprint?

[00:13:42]In the oldest light we can see… the  cosmic microwave background. It’s the faint afterglow of the Big Bang that  fills the entire sky. Penrose and his team argue that some regions are warmer  than they should be. Not random specks, but circular patches roughly 8  times wider than the full Moon.

[00:14:00]In a 2020 paper, the team reported finding  these circles in data from both the Planck and WMAP satellites. They called them Hawking  Points. And if their interpretation is correct, these aren't just random features.  They're relics from giant black holes that existed before our universe was born. Other researchers examined the same maps and reached a different conclusion. When they  reran the analysis, the signal became much less impressive. The problem is that if you  search a huge dataset for unusual patterns, you'll almost always find some. Think about spotting shapes in clouds. If you start looking for circles,  after a while, it’s easy to find them.

[00:14:36]So, are these real scars from a universe before  ours…or just patterns hiding in the noise?

[00:14:43]Either way, it sets the stage  for an academic civil war.

[00:14:46]Researchers are working toward one of the biggest  questions in science: how the universe began.

[00:14:51]Careers, grants, and scientific reputations all  hinge on getting that answer right. The stakes feel personal because they are. And right now, that search is playing out in real time. In journals and at conferences, teams are arguing over JWST’s earliest  galaxy candidates. Whether they really are as massive and distant as they first appear,  or whether effects like cosmic debris are making them look more extreme than they truly are. But this isn’t just about distant galaxies, it’s also about our place in it. Look down at your hands. Every atom in them was forged inside ancient stars. In some  versions of cyclic cosmology, even the light around you might not be new in a cosmic sense.  It’s just recycled from an earlier universe.

[00:15:35]So where does that actually leave us? Not with a broken Big Bang.

[00:15:40]The basic story surrounding it still holds.  The universe is expanding, and if you run the clock backwards, everything points to a  hot, dense beginning. It’s written into the simplest elements in space: hydrogen and helium  still appear in exactly the amounts the theory predicts. When everything is added up, the age of  the universe is still around 13.8 billion years.

[00:16:00]New surveys are already pushing deeper into  the early universe, and those little red dots may change how we think galaxies first formed. What ever JWST finds, this isn’t a crisis in cosmology, but a picture of the universe that’s  still being filled in, one piece at a time.

[00:16:16]It looks like the James Webb Space Telescope  has just uncovered another mystery… and it’s not the only one hiding out there. If you want to  go deeper, watch “50 Surprising Facts About Space You Didn't Know” to see what else the universe  is keeping from us. Or click on this video.
