It would make sense to me that matter does not disappear or get infinitely crushed into nothing.
What I can believe is that matter, with respect to a black hole, does get changed/re-shaped. I would like to think that it has gone through the beginning stages of recycling.
It would make sense. As like any thing in life, change of a material's state does occur when a force/set of forces act upon/against it.
And as for the thinking that a black hole eventually fades away or gets weaker, well, simply, why not? Everything else does, what makes a black hole so different than anything else in the universe.
Actually, the thought that the other side of a black hole is a "baby-universe" is silly. How, as scientists, can we even speculate something like that?
