Can Black Holes Truly Absorb All Matter and Energy?

[Shailesh Pincha]

Black hole is considered an almost ideal black body by being a perfect black hole. But does it ideally absorb everything coming in the vicinity of its impact? Is it really possible for anybody to either ideally absorb or ideally radiate energy?

Everything that comes so close that it crosses the event horizon cannot come back, yes.

Is it really possible for anybody to either ideally absorb or ideally radiate energy?

Yes.

Is it experimentally proven or something like that which proves that black hole absorbs everything or it is just theorised?

There are no proofs in physics.
Experiments are in very good agreement with general relativity, a framework which does not allow things to escape. There is no alternative theory that would allow things to escape without being in conflict with observations.
