Was our universe born inside a black hole in another universe?

The current explanation of the universe’s origins relies on clumsy assumptions and can’t explain most subatomic particles. A small tweak to general relativity solves these problems – and seemingly proves the universe must have come from a black hole elsewhere.

General relativity, however, can’t explain inflation, so another theory is required to account for it. There’s nothing technically wrong with that, but it’s an inelegant solution, and physicists tend to prefer an all-encompassing explanation to a bunch of piecemeal solutions. That’s not the only issue with the current explanation – it can’t deal with many properties of subatomic particles, consigning them entirely to the realm of quantum mechanics.

Under normal circumstances, this is just an interesting bit of math, and torsion doesn’t really affect anything. However, if densities are increased tremendously, then torsion has some very significant effects. Most intriguingly, torsion makes it impossible for black holes to form singularities. And if singularities are impossible, then what’s at the center of black holes?

This potentially means that many of the black holes in our own universe are the incubators of entirely new universes, each separated by the infinite time gap of the event horizon. That said, some properties of the mother universe could trickle through to its daughters, and detecting some of these properties could actually provide experimental proof of the theory. In fact Poplawski speculates this inheritance of properties could solve another great mystery of cosmology.

The so-called arrow of time, in which time flows in one direction but not another, is a fundamental aspect of our experience. This isn’t accounted for at all by physics, as all of its laws are apparently time-symmetric in that they work just as well whether time flows forwards or backwards. However, the passage of matter through the event horizon would provide a time asymmetry in the new universe, giving it a forward arrow to time. In that way, time itself is a gift of our mother universe on the other side of the black hole.
