Question

what is black hole who is discovered black hole radiation and when​

Answer 1

Answer:

Black hole is a celestial object that has a gravitational field so strong that light cannot escape it and that is believed to be created especially in the collapse of a very massive star.

The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958.

Black hole radiation, also known as Hawking radiation is named after the theoretical physicist Stephen Hawking, who provided a theoretical argument for its existence in 1974. Hawking radiation reduces the mass and rotation energy of black holes and is therefore also known as black hole evaporation.
