Discover what if the Universe is an infinite donut, and how this theory could change our perception of reality. Immerse yourself in the exciting world of cosmology and the strange possibilities of infinite space.
Sometimes I feel like we are too confident in our understanding of how the Universe works.
Yes, science has many theories, formulas, and observations. We know that the Universe is expanding. We know about the existence of black holes — objects with such powerful gravity that not even light can escape. There are also notions that one day the expansion will stop, and everything will start to collapse back.
But what if we are not looking at the whole picture, but only a tiny fragment of it?
What if the Big Bang was not the beginning of all that exists, but merely the birth of our Universe from something else?
Imagine for a moment that the Universe is shaped like a vast torus — in simpler terms, a giant doughnut. We exist somewhere on its surface and perceive the movement of galaxies as the expansion of space. But perhaps all the matter after the Big Bang does not scatter chaotically into the void but moves along a curved path within this structure.
Then an amazing thing happens: everything that once "exploded" after the bang may eventually return back to the point of its birth.
To the black hole.
And here the very idea of a black hole begins to look different.
Perhaps it's not the end of matter and not a cosmic trash can. Maybe a black hole is a transition. A door between the states of the Universe. An entrance and an exit at the same time.
Matter and energy fall in, are compressed to their limits, and then somewhere on the other side, a new Big Bang occurs — the birth of a new Universe.
Then the Universe turns out to be not a one-time event, but an endless cycle:
birth → expansion → return → new birth.
Without an absolute beginning.
Without a final end.
Just constant rebirth.
And now imagine an even stranger thought.
We observe many black holes. But what if each of them is a passage to other areas of this same "cosmic doughnut"? Or even to other universes existing alongside ours, but not directly accessible.
Then everything that is being pulled in by a black hole today might have once been birthed by it — just from the other side. Through its own Big Bang.
This creates a closed loop of the cosmos, where the end is simultaneously the beginning.
And perhaps the Universe is not an endless void, but a perfectly closed system that eternally creates itself.
