A black hole is only an extremely condensed state of matter, and ordinary matter can reach it by breaking through a boundary of its own gravity. The early black hole only destroyed the molecular structure and atomic structure of the absorbed matter, that is, the absorbed matter became a part of the black hole. And if the medium-term black hole, it should be able to affect space. The "absorbed" matter is elongated on the way to be inhaled and hovers towards the black hole. Break through a speed limit (maybe the speed of light) on the way, and break through a very fragile space that has been destroyed by the huge gravity of the black hole. As for where you went after the breakthrough, LZ's free imagination may have gone to another dimension, another world full of infinite possibilities. In the later period, the gravity of the black hole has reached the limit of the universe, which can even affect the flow rate of time and even lead to the disorder of time. In a possible world, there is another possibility, another infinity, and even a black hole has become a world. Everything around a black hole is changing.
At a certain time, the universe can't bear the black hole, then the black hole may explode, and all matter will return to the origin in another form (conservation of matter), or create another world, another universe and another dimension. Or gradually devour all the substances in this universe, condense into a "point" with infinite volume, infinite density and infinite internal energy, and produce a big bang. From the big bang we imagined, we began another reincarnation, and the world continued.
