What is behind a black hole?
hello I was researching a lot
Because it is not known, and probably not known for fairly obvious reasons.
There is speculation the idea of wormholes, that somehow would connect "the end" of a black hole with another black hole, white or whatever.
If you really mean behind the event horizon, for there is space exactly like ours. That if the force of gravity is so brutally immense tidal forces that would destroy you before you can see anything.
