Stephen Hawking
Explanation:
hope it helps you.
Answer:
Stephen William Hawking is his name. he was the one who formulated theory of black holes.
Hawking went on to show that while large black holes emit radiation as a slow dribble, small ones glow, emitting lots of radiation quickly. He showed that all black holes eventually evaporate or boil themselves away, expiring in a brilliant burst of energy equivalent to a million 1-megaton hydrogen bombs
Explanation:
The idea of a body so massive that even light could not escape was briefly proposed by astronomical pioneer and English clergyman John Michell in a letter published in November 1784. Michell's simplistic calculations assumed such a body might have the same density as the Sun, and concluded that such a body would form when a star's diameter exceeds the Sun's by a factor of 500, and the surface escape velocity exceeds the usual speed of light. Michell correctly noted that such supermassive but non-radiating bodies might be detectable through their gravitational effects on nearby visible bodies.[20][7][21] Scholars of the time were initially excited by the proposal that giant but invisible stars might be hiding in plain view, but enthusiasm dampened when the wavelike nature of light became apparent in the early nineteenth century.[22]
If light were a wave rather than a "corpuscle", it is unclear what, if any, influence gravity would have on escaping light waves.[7][21] Modern physics discredits Michell's notion of a light ray shooting directly from the surface of a supermassive star, being slowed down by the star's gravity, stopping, and then free-falling back to the star's surface.[23]
