Physicists observationally confirm Hawking's black hole theorem for the first time. Study offers evidence, based on gravitational waves, to show that the total area of a black hole's event horizon can never decrease.Jul 1, 2021
Who discovered about black hole?
Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term "black hole" was coined many years later in 1967 by American astronomer John Wheeler.
What is Stephen Hawking’s theory on black holes?
That's where Hawking came in. In 1971, he suggested that black holes formed in the chaotic environment of the earliest moments of the Big Bang. There, pockets of matter could spontaneously reach the densities needed to make black holes, flooding the cosmos with them well before the first stars twinkled.
What was Stephen Hawking’s discovery?
black holes emit radiation Dr. Hawking is best known for his discovery that black holes emit radiation which can be detected by special instrumentation. His discovery has made the detailed study of black holes possible. Stephen Hawking was born in Oxford, England on January 8, 1942.
Was Stephen Hawking the first person to discover black holes?
Black holes are created from the gravitational collapse of pre-existing matter such as stars. But it's also possible that some were created spontaneously in the very early universe, soon after the Big Bang. Hawking was the first person to explore the theory behind such primordial black holes in depth.
Who discovered white hole?
The possibility of the existence of white holes was put forward by Russian cosmologist Igor Novikov in 1964.
Does time stop in a black hole?
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.
What is Stephen Hawking’s IQ level?

Is Hawking radiation correct?
Hawking radiation has never been observed, but if it exists the information lost when objects enter a black hole might be carried out of the black hole via this light. Thus the information isn't truly lost. If Hawking radiation is real, that also means that black holes follow the laws of thermodynamics.
Why is Stephen Hawking disabled?
In 1963, Hawking was diagnosed with an early-onset slow-progressing form of motor neurone disease (amyotrophic lateral sclerosis – ALS, for short) that gradually, over the decades, paralysed him.
