If you tumble into the black hole at the center of the Milky Way, it’s conceivable that you (or at least the shredded particles that were once you) will end up in another universe.
The more I read about the theory that our universe resides entirely within a black hole the more it makes sense.
According to this theory the Big Bang was the collapse of a star forming the black hole that our universe resides in. This would also mean that within each black hole resides another universe.
As if space wasn’t mind blowing enough, eh?
