If you fall into a black hole, you will see the entire future of the Universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into. ....
None of this is true.
A black hole does not contain "history," but destroys it. Neither is there any necessity in physics for another space time on some hypothetical "other side" of a black hole. If that were so, the black hole would weigh less than the matter destroyed going into it.
They don't.
There CERTAINLY may be other mechanisms for alternate universes to exist.

This is not complicated. Let's take a much easier case to understand, like a neutron star. It's "solid." It's a star that has ran out of fuel and has shrunk down to a compact, solid mass - not of atoms, but of neutrons. It is only a few miles in diameter, but weighs more than our sun.
It is millions of time more dense than say, matter such as the Earth is made of. You fall toward a neutron star. By the time you become a thin layer on the surface of the star, no atoms of your body exist. All that information - and organization - has been destroyed. Is "Information" preserved? Electrons and protons have escaped into interstellar space.
The black hole, though, sucks it all in. Now the questions about "information preservation" concern themselves with outflow of mostly, photons. At this point let's compare the discussion with the original argument - the preservation of HISTORY. No history can be preserved after the dissolution of matter itself. Therefore, there can be no "other side of the black hole." Were that the case we would see outflows in our universe, where black holes existed in some other universe. And they would be outflows of what, exactly? This is where the issues of conservation of energy and momentum become troublesome.
"Falling into a black hole, you would see...." NOTHING because there would be no "You" whatsoever, you would be as dead as if you fell into the Sun.
Not meaning to pick on Spendulus, here, but...
The whole idea of talking about these things is speculation. Stars and their makeup, outside of spectral analysis, is essentially unknown. Right inside our own little solar system, we are finding new things - sometimes anomalies - that we never thought existed, and that are tweaking our understanding of astrophysics in ways we would never have dreamed of a couple of decades ago.
Personally, I consider that all of our information is kept and maintained by God. Psalm 147:4 says about God:
He determines the number of the stars and calls them each by name.
Not only does God know every star by name, but He determines them, causing their existence. In similar ways He knows each of us and everything about us.
