| Not from the Big Bang? New Theory Suggests the Universe Came from a Giant Black Hole. |
If you’ve always believed the universe began with the Big Bang, it might be time to consider another possibility. A new theory from scientists at the University of Portsmouth, led by physicist Enrique Gaztañaga, proposes that our universe may have originated from a supermassive black hole—not from a massive explosion like we've been taught.
A New Theory: The Universe "Bounced" from a Compressed Phase
According to the traditional view, the Big Bang was the beginning of everything—space, time, and matter emerged from an extremely dense point. But this model has its flaws, especially when it comes to the concept of a "singularity," a state of infinite density where physics breaks down.
This is where the new theory gets interesting. The Portsmouth team combined two of the most powerful scientific principles—general relativity and quantum mechanics—to build a model of the universe that doesn’t begin with a singularity. Instead, it starts with a phase of intense compression that then "bounces" and begins to expand. All of this fits within known physical laws, without the need for unproven theories or exotic assumptions.
Naturally Explaining Two Expansion Phases
What makes this theory even more exciting is how it explains the universe’s two major expansion phases:
-
Rapid inflation just after the universe's birth, and
-
The current acceleration of expansion, usually attributed to dark energy.
Normally, scientists introduce extra variables like an "inflation field" or mysterious energy to explain these. But in the "black hole bounce" theory, these phenomena arise naturally as part of a cosmic cycle. No exotic elements needed—just the physics we already know.
Predictions and How to Test Them
This theory isn’t just philosophical. It makes testable predictions. For example, it suggests that the shape of the universe should be slightly curved—like the surface of a sphere. That curvature would be a trace of the compression phase before the bounce.
The good news? Space telescopes like Euclid are capable of detecting this curvature. If observations match the theory, it would provide strong support that the universe really did form in this way.
Even more compelling, the universe’s expansion rate calculated by this model matches what astronomers observe today. So it’s not just an abstract idea—there’s math and data to back it up.
Explaining More Cosmic Mysteries
This theory might also help answer some of the biggest questions in astrophysics:
-
Where did supermassive black holes at galactic centers come from?
-
How did dark matter form?
-
Why do galaxies have the structure they do?
The answers may lie in objects that survived the extreme compression phase and continued on into the expanding universe we live in now.
Are We Living Inside a Black Hole?

Here’s the wildest part of the theory: we might be living inside a black hole. This black hole could have formed inside a much larger universe. That means everything we see and experience could just be a small part of an endless cosmic cycle—governed by gravity and the laws of quantum physics.
Time to See the Universe from a New Perspective
This theory is still being tested through space missions like ARRAKIHS and cutting-edge telescopes. But one thing is clear: the more we explore the cosmos, the more we may need to rethink our understanding of how it all began.
So maybe the Big Bang wasn’t the beginning of everything. It might just have been a bounce in a never-ending cosmic cycle.
