We live in a black hole.

Some fairly mind-blowing physics is involved here, but the gist is that
Nikodem Poplawski of IU-Bloomington used a modified version of Einstein’s
general relativity equation set that takes particle spin into account.
Including this variable makes it possible to calculate torsion, part of
the geometry of space-time. It also gets rid of the black hole
singularity, a phenomenon that general relativity cannot explain.
In a study published earlier this year, Poplawski said when the density
of matter reaches epic proportions, torsion counters gravity. This
prevents matter from compressing indefinitely to a singularity of
infinite density. Instead, matter rebounds like a spring, and starts
expanding again.
In Poplawski's latest study, his calculations show that space-time inside
the black hole expands to about 1.4 times its smallest size in as little
as 10-46 seconds -- two orders of magnitude faster, for lack of a better
word, than the Planck time. This brisk bounce-back could have been what
led to the expanding universe that we see today.
But here's the real kicker: as Poplawski says, we may not be living in
our universe at all; we might be living inside a rebounded black hole
that exists in a different universe.
We could tell by measuring the preferred direction of our universe. A
spinning black hole would have imparted some spin to the space-time
inside it, which would violate a law of symmetry that links space and
time. This might explain why neutrinos oscillate between their antimatter
and regular-matter states.
