does anything which enters black also get out of it ever ,if no then why?
Answers
Answer:
If gravity obeyed Newton's law of universal gravitation, then gravity would indeed have no effect on light. ... As a result, once a ray of light enters a black hole, it can never exit. For this reason, a black hole is truly black and never emits light.
No, nothing ever gets out of black holes....
Why can light escape a black hole?
A black hole is a region of space whose mass is so large and dense that not even light can escape its gravitational attraction. ... Not only are they able to emit huge jets of plasma, but their immense gravity pulls in streams of matter into its core.
The gravitational pull of a black hole is so strong that nothing, not even light, can escape once it gets too close. ... As black holes gobble up the matter in their surroundings, they also spit out powerful jets of hot plasma containing electrons and positrons, the antimatter equivalent of electrons.
