When NASA unveiled the James Webb Space Telescope (JWST) in late 2021, the scientific world was ready for a surprise. But not this sort. Within a mere few years, JWST has produced mind-boggling data that not only tests our beliefs — it promises to rewrite the very pillars of physics established by Albert Einstein.
We're discussing a profound, disturbing implication: that the universe is not operating by the rules we believed to be inviolable. And even worse? It may already be too late to comprehend it.
Einstein's Legacy — Now Under Siege?
Einstein's General Theory of Relativity, released in 1915, provided us with the current understanding of gravity: heavy objects warp space and time, and that warping governs the trajectory of all of the universe's mass. It's a beautiful, elegant system — and it's performed fantastically for more than a century.
But here's the kicker: the James Webb Telescope has started to observe galaxies so large, so early in the history of the universe, that they shouldn't be there — ever. Some of these early galaxies are only a few hundred million years old, but already they're big, grown-up, and rich in chemistry. In Einstein's cosmology, that much matter shouldn't have had time to coalesce.
That is, our whole picture of how the universe developed — from the Big Bang to the present — could be incorrect.
Galaxies Too Big to Be True
One of the first deep field pictures taken by JWST revealed galaxies that were only 300 to 500 million years old after the Big Bang. That was a given. What wasn't is how big and what shape they were. They're ten times bigger than our models indicated. They're disk-shaped, not chaotic — which means they did not experience the chaotic early phase of development our textbooks outline.
This puts a kink in the "bottom-up" theory of galaxy formation — the theory that small things built up first and accreted into large objects over billions of years. Instead, these giants seem to have emerged completed, out of thin air.
And it only gets stranger.
Time May Not Work the Way We Think
To account for these impossible observations, however, some physicists are exploring a profoundly disturbing notion: what if time doesn't work as we believed? What if the "arrow of time," one of the fundamental cornerstones of physics and human existence, isn't quite as absolute as we imagined?
Some hypotheses propose time itself might be emergent — an emergent byproduct of more fundamental quantum processes. If JWST's findings are correct, they can be revealing faults in our very understanding of causality. Past, present, and future may not be so linear — or distinct — as Einstein thought.
In other words: what if the universe isn't evolving, but replaying, or worst of all — looping?
The Multiverse, or Something More Sinister?
Others suggest these anomalies might point to something even more bizarre: evidence of other universes. Some cosmologists argue that what we’re seeing could be the gravitational echo or residue of adjacent universes pressing against our own.
Another camp believes these ancient galaxies might be remnants of a previous universe — a cosmic reboot that occurred before the Big Bang.
This would make the Big Bang a beginning rather than a bounce — the result of a collapse that preceded it. The universe need not be a single occurrence, but an ever-repeating cycle of birth, death, and resurrection.
So… What Can We Do?
Here's the scary part: perhaps nothing.
Our physics textbooks are not merely stale — they might be fundamentally incorrect. If the laws that govern time, space, and matter aren't what we assumed, we might have no means to test — much less control — the underlying forces at work.
And besides, if the universe exists as part of some multiversal chain or loop, then our fate is already set — decided not only by laws of physics, but by a cosmic framework we can never leave or even fully comprehend.
That's the existential horror creeping in: we might never have a way to know.
Hope — or Humility?
But it's not all bad news.
Science loves to be disproven. Each time we've needed to redraw the rules, humanity has advanced. Perhaps JWST is merely illustrating how much we don't know — and that's a wonderful thing.
It makes us think bigger, dig deeper, and challenge our most revered truths.
Still, as we gaze deeper into the abyss with this cosmic gaze, we're only just starting to realize that the universe might be stranger, older, and much less kind than we could ever have dreamed.
And the scariest part?
It's just beginning.
