Stephan Hawking theory of Black holes

Stephen Hawking, who died on  Wednesday, was a  inspirational and influential scientist. Despite living most of his life with a serious neurodegenerative disease Als , He got fame and respect Form the scientist and Fiction lovers .

However he wouldn't remember for his Lively Attitude but also for Work in the Department of Black Hole theory. 

What is The Black hole actually ?

A black hole is a region of spacetime  exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed.[4] In many ways a black hole acts like an ideal black body, as it reflects no light.
Moreover, quantum field theory in curved spacetime  predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

In the bottom line we can define Blackhole as the Star who ia dead now due to his Uncontrolled Gravitational forces and It shrink to die and time And matter Deform on that star. And it is so powerful that Even the light Can't past through it .

Work of Stephan Hawking Over Black hole

In the 1970s, Hawking, using a lot of math, essentially took the temperature of a black hole.
He did this by combining insights from both Einstein’s theory of relativity (which describes how gravity works at grand scales) and quantum mechanics (which describes how the very smallest components of the universe work). These are the two major theories about how the universe works that scientists have been searching for decades to combine. And they both come into play at the event horizon of a black hole, the boundary beyond which gravity is so strong that not even light can escape.
Before Hawking’s discovery, black holes were typically thought to be objects into which things go in but never come out (the thinking actually stems in part from Hawking’s work describing singularities within black holes.)
Essentially, Hawking showed that black holes can, like so many objects in our universe, shrink and die. He even turned this insight into a bit of advice for us all: “Things can get out of a black hole. ... So if you feel you are in a black hole, don’t give up — there’s a way out.”
