Stephen Hawking didn't, this had already been shown by the German physicist Karl Schwarzschild in 1916 in his analysis of Einstein's General Theory of Relativity published the year before.
What Stephen Hawking did was prove that microscopic black holes can "evaporate", radiating matter and eventually exploding!
Yes, matter and energy can come out of a black hole through a process called Hawking radiation, which was proposed by physicist Stephen Hawking.
I think that it was Stephen hawking NO it was your mum
Stephen Hawking sent his high school into a black hole
he is obviously black.
The possibility of black holes was known before Stephen Hawking. Stephen Hawking's contribution to the theory was mainly that a black hole would gradually evaporate, due to certain quantum effects that occur close to the black hole's event horizon.
Stephen Hawking discovered many different things.
Stephen Hawking
Studying space and black holes
Actually he didn't.
1970 - Stephen Hawking's essay titled "Black Holes" won the Gravity Research Foundation Award in January 1971.
Stephen Hawking did not discover the law of everything, but he did have big ideas on how the universe began, and also on black holes.
Stephen Hawking's research on black holes led to the concept of Hawking radiation, which proposed that black holes are not completely black but emit radiation. This idea resolved the paradox of black holes violating the laws of thermodynamics by showing that they can slowly lose mass and energy over time.
