Professor Stephen Hawking proposed that black holes interact thermodynamically with the universe in specific ways; for example that radiation could be generated by quantum effects near the event horizon (Hawking radiation) and thus carry mass away from it, per Einstein's proof of the equivalency of mass and energy; thus a black hole's mass could decrease over time and eventually it could "evaporate" entirely.

How does Stephen hawkings theory of black holes help us?
The discoveries of Stephen Hawkings (and lots of other scientists) help us get a better understanding of how the Universe works. It is not always clear in advance what benefits we get from such an understanding, but if you look at the past, an understanding of the Universe has helped us quite a lot.
Can black holes dies?
Black holes do not die but they can evaporate.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Are dead stars black holes?
Yes. They get sucked into black holes all the time!
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
What were some of Stephan Hawkin's contributions to astronomy?
For one, he came up with the Hawking radiation, which is emitted by black holes.
Why is stephan hawking significant?
well professor hawking was the one who figured out the theory that black holes can emit radiation
What did Stephen hawking say about black holes?
His major contribution to the theory of black holes is that they will gradually evaporate, due to certain quantum effects close to the event horizon.

Why is Stephen Hawkings Famous?
Stephen Hawking is famous for his research on black holes. He is one of the most famous cosmologists and theoretical physicists alive. He is known, amongst other things, for the description of radiation that escapes from the region near a black hole (Hawking radiation) and the theory of the evaporation of black holes. Together with Roger Penrose, he showed that Einstein's General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. Hawkings' scientific works (together with others) include providing theorems regarding singularities, the framework of general relativity. He is also famous because he has accomplished so much, despite his debilitating muscular atrophy due to ALS (amyotrophic lateral sclerosis). from his work in black holes and working through his disablities. Yes he was. Stephen Hawking was born on January 8th 1942 and is known for his contribution to cosmology and quantum gravity.
Who was HAWKINGS?
Stephen Hawking is a famous British theoretical physicist, known for his work regarding black holes and his ALS, which confines him to a wheelchair and forces him to use a computerized voice synthesizer. I must add.. the question should be corrected to 'Who is Steven Hawking?'.. The word was implies that he is dead.he is still studying the black holes
When did stephan hawking find out what black holes were?
Most likely in the University classroom as an undergraduate student, that's where most people of his generation learned about black holes. But of course what he learned about was ordinary stellar black holes.It was much later when he made his own "what if" hypothesis on microscopic black holes. After solving the equations of general relativity for this case and including the effects of quantum mechanics, he made his theory including Hawking Radiation, evaporation of black holes, and their eventual explosion. This remains theoretical, as his black holes have still not been observed.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Can black holes dies?
Black holes do not die but they can evaporate.
What has the author Stephan Kaluza written?
Stephan Kaluza is a German author known for his work in the field of theoretical physics, particularly in the area of quantum gravity and cosmology. He has published research papers on black holes and the intersection of quantum mechanics and general relativity.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
