"This is Going to Hurt!" James Webb Telescope New Deep-Field Image with FLAMINGO Shatter our Physics

[00:00:00]Yeah, that's blotch here. So, it's really probing basically the earliest structures we know in the universe.

[00:00:05][music] >> When you look at this image, there are lots of splodges all over the place.

[00:00:09]What made you look at that one in particular? [music] >> We have been seeing this object already in the very early data we obtained nearly 2 years ago. And I think the surprising thing was that it's actually very bright. And so, our initial reaction was that, well, it cannot be that distant because it's too bright.

[00:00:25]And so, we took better data and in particular we also took spectroscopy. We could clearly see that, no, that this yellow blob here is really this most distant galaxy that we have ever seen.

[00:00:42]>> One of the biggest and most mysterious questions about the universe is this.

[00:00:47]What happened before the universe began?

[00:00:50]What started everything in the first place? How big is the universe really?

[00:00:55]And is it truly infinite? Or does it have some kind of edge? These are some of the hardest questions humans have ever asked, and even today, science does not have clear answers.

[00:01:06]We do have theories that explain what happened after the universe began, but even those theories have problems. In recent years, discoveries made by the James Webb Space Telescope have started to challenge our basic understanding of how the universe evolved. Recently, on January 5th, 2026, the James Webb Telescope made another surprising discovery. A global team of astronomers, led by researchers in Canada, found something completely unexpected in the early universe. A galaxy cluster filled with extremely hot, boiling gas that existed just 1.4 billion years after the Big Bang. According to current scientific theories, such extreme conditions should not appear so early.

[00:01:47]Normally, gas inside galaxy clusters is expected to heat up slowly over billions of years as these structures grow and settle. But this cluster is both much younger and far hotter than scientists ever predicted. Finding such intense heat so early raises serious questions about whether our existing models of the universe are incomplete or even wrong.

[00:02:10]This is not an isolated case.

[00:02:12]Many discoveries from the James Webb telescope in the early universe have become a major headache for scientists.

[00:02:18]Again and again, Webb is revealing objects that are too massive, too organized, or too energetic for their age. In many ways, [music] these findings are shaking the standard model of cosmology. Scientists are now struggling to explain what is really happening. Amid all these debates, one of the most worrying and challenging questions is about the expansion of the universe itself. For decades, scientists believed that galaxies are moving away from each other because space itself is expanding. But, new observations from the James Webb telescope are now challenging this expansion model.

[00:02:55]Some scientists are even suggesting that what we see as cosmic expansion might be an illusion. They have proposed a new model to explain the motion of galaxies.

[00:03:03]>> [music] >> And surprisingly, this new idea seems to match the observations better than existing theories. Let me explain it to you in a simple way. You know, the way galaxies move in the universe is really strange. When we point our telescopes at deep space, >> [music] >> we notice something surprising. Almost all galaxies are moving away from us.

[00:03:22]And not just that, the farther away a galaxy is, the faster it seems to be moving away. This strange pattern confused scientists for a long time, until they came up with a bold idea.

[00:03:33]Maybe the universe itself is expanding.

[00:03:36]That means it's not the galaxies flying through space on their own, but instead, the empty space between galaxies is stretching. Kind of like dots on the surface of an inflating balloon. And here's the interesting part. The more space there is between two galaxies, the faster that space expands. So, distant galaxies appear to move away faster simply because there's more space between us and them. Scientists believe this expansion began around 13.8 billion years ago, right after the Big Bang.

[00:04:05]But, unlike an explosion from a central point, this expansion happened everywhere at once. There's no center and no edge to it. This idea has been part of the standard cosmological model for years. And while it helped answer many big questions, new discoveries are now challenging this entire picture.

[00:04:23]This is where the James Webb Space Telescope comes in. Some of its early observations suggest something unexpected. The expansion of the universe might not be happening evenly in all directions.

[00:04:33]>> [music] >> In other words, the universe may not be expanding at the same rate everywhere, which contradicts what inflation and dark energy theories predicted. Even more surprising, Webb's data hints that the universe might not be as smooth and uniform as we once thought. That's a big deal because inflation theory is based on the idea that the universe looks the same, no matter where you are or which direction you look. If that's not true, then our most trusted models, the ones we've relied on for decades, might need serious revision. But, it's not just the discoveries from the James Webb Space Telescope that are challenging the expanding universe theory.

[00:05:11]This idea has faced serious questions for decades with several long-standing problems that have continued to puzzle and frustrate scientists.

[00:05:20]One of the biggest problems is that we still don't know why space is expanding in the first place.

[00:05:26]We can see that galaxies are moving apart, but what is really causing that movement?

[00:05:31]Scientists have given a name to this mysterious force, dark energy.

[00:05:35]But, here's the truth. Dark energy is not something we fully understand. In fact, we've never seen it directly. It's just a name for something we know must be there to explain the acceleration of the universe's expansion.

[00:05:48]But, recent discoveries made by the James Webb Space Telescope have revealed something even more surprising. The accelerated expansion of the universe appears to be slowing down.

[00:05:58]This suggests that dark energy, the mysterious force believed to be driving the universe's expansion faster [music] and faster, may actually be weakening over time.

[00:06:08]If this is true, it raises some very serious and uncomfortable questions for science.

[00:06:13]Why is dark energy losing its strength?

[00:06:16]What is causing this mysterious force to change? And if dark energy is not constant, then our entire understanding of the universe's future could be wrong.

[00:06:25]This unexpected finding is once again pushing scientists to rethink some of the most fundamental ideas in modern cosmology.

[00:06:33]Another confusing part is how this expansion behaves.

[00:06:37]According to the theory, only the space between galaxies is expanding, but not the galaxies themselves or solar systems or atoms.

[00:06:45]This works mathematically, and most scientists agree that local forces like gravity or electromagnetic forces are strong enough to resist expansion.

[00:06:55]But, this creates a strange idea.

[00:06:57]Expansion is happening, but only in certain places and not in others.

[00:07:02]That makes people wonder, is space really expanding everywhere, but things like atoms and planets are just holding themselves together against it?

[00:07:09]Or is expansion something that only happens on big scales and simply doesn't exist at small ones?

[00:07:16]There's still a lot of debate about the actual meaning of expansion. Is it real or just how it appears to us when we look at distant galaxies?

[00:07:24]However, to explain all these mysteries, scientists have recently proposed a new model of the universe named timescape cosmology.

[00:07:33]In this model, scientists highlight the significant influence of massive cosmic voids and structures on the nature of time.

[00:07:41]In this new cosmological model, scientists have revealed that the expansion of our universe is not driven by dark energy, but is an illusion created by time.

[00:07:51]They propose that time flows slower in regions of space where the concentration of matter is higher.

[00:07:57]For instance, [music] an atomic clock situated within a galaxy might tick up to a third slower compared to an identical clock positioned in the middle of a vast empty void.

[00:08:07]Now, think about this over the vast time scale of the universe.

[00:08:11]The universe is about 13.8 billion years old, but in regions with little matter, like cosmic voids, time has been passing faster. So, billions of additional years may have passed in these voids compared to the matter-rich regions.

[00:08:25]This means that the universe doesn't have a single unified age as we often imagine.

[00:08:30]Instead, the age of the universe could vary depending on where you are.

[00:08:35]The age of the universe may be greater in the cosmic void than in [music] a denser region of space.

[00:08:41]Here's where it gets even more fascinating. Since so much more time has passed in the voids, these regions have experienced more cosmological expansion.

[00:08:50]In simple terms, the universe has been stretching more in these less dense areas.

[00:08:55]If you're looking at an object on the far side of a void, it would appear to be moving away from you much faster than an object on the near side of the void.

[00:09:03]This is because the space within the void has expanded more over time.

[00:09:07]Now, imagine this effect across the entire universe.

[00:09:10]Over time, the voids become a larger and larger part of the cosmos because they are expanding more rapidly.

[00:09:17]As a result, when we observe the universe, it creates the illusion that the overall expansion is accelerating.

[00:09:24]But in this model, there's no need to introduce dark energy.

[00:09:28]Instead, [music] the faster expansion in the voids naturally accounts for what we see.

[00:09:33]In 2017, astronomers from the University of Canterbury in New Zealand tested timescape cosmology against observations and found that it was a slightly better fit than lambda-CDM to explain cosmic expansion.

[00:09:47]For now, this is just another theory, one that seems to explain the motion of galaxies better than earlier ideas.

[00:09:53]However, the expansion of the universe is still not fully understood. Maybe it never will be.

[00:10:00]But our endless curiosity about nature and how it behaves has already taken humanity a very long way in our journey through time.

[00:10:08]So, what do you think? Is dark energy really causing the universe to expand?

[00:10:13]Or is this expansion simply an illusion created by time itself? Share your thoughts in the comments below.
