The Big Bang is commonly thought of as the explosive beginning of the universe—the single moment when space, time, and matter came into being. But what if that wasn’t a beginning at all? What if our universe emerged from something else—something more familiar and yet radical?
In a recent paper in Physical Review D, my colleagues and I present a striking alternative. Our calculations suggest that the Big Bang was not the beginning of everything, but rather the consequence of a gravitational contraction, or collapse, that formed an extremely massive black hole — with a subsequent bounce inside it.
This concept, which we call the black hole universe, offers a completely different view of the origin of the cosmos, but it is entirely based on known physical principles and observations.
