How is Steven Hawking involved in black holes?

Answer 1

Hawking proposed that black holes would 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.

Answer 2

Stephen Hawking was a renowned theoretical physicist known for his work on black holes. He proposed that black holes emit radiation, now known as Hawking radiation, which led to groundbreaking advancements in our understanding of these celestial objects. Hawking's work on black holes contributed significantly to the field of theoretical physics and has left a lasting impact on our understanding of the universe.

Answer 3

Black hole theory dates back to late 18th century with John Michell who described matter falling towards a body of sufficient mass such that its speed could be accelerated to that of light speed, although many implications were not fully described until Einstein's general theory, the field equations of which were solved by Schwarzschild and others. Professor Hawking's later contributions which involved the nature of the universe and its possibly initial black hole singularity-like state and were partly inspired by mathematician and cosmologist Roger Penrose. Professor Hawking later studied quantum mechanics, from which came perhaps his most famous addition to black hole theory, the posit that black holes interact thermodymanically with the universe and emit radiation which was later known as Hawking radiation.

Hawking has commented that his progressive illness and physical challenges gave him much time for meditation and in that respect the illness itself contributed indirectly to his contributions to the growing body of black hole theory.

Answer 4

Mainly, that a black hole will gradually evaporate.

=================================

Prof. Stephen Hawking discovered that black holes evaporate due time. Black holes should shine and not be black. Its because of pair-production and gravity being maximum at the event horizon to pull out one of the particles and let the other escape thus giving out light.

Answer 5

Yes. He worked on a theory that black holes radiate small particles called Hawking Radiation.

Answer 6

Steven Hawkings is the man that is credited with discovering black holes, even though Einstien predicted that they could appear 50 years before.

Answer 7

Stephen Hawking did not discover Black Holes, nor was he the first to propose their existence. He did make use of them in his theoretical work.

Answer 8

No he did not but he did prove that Black Holes were real

Answer 9

Actually he didn't.

Answer 10

That black holes will slowly evaporate.
