The black hole area theorem
, which Hawking derived in 1971 from Einstein's theory of general relativity, states that it is impossible for the surface area of a black hole to decrease over time.
What did Hawking prove about black holes?
In 1971, Stephen Hawking proposed the area theorem, which set off a series of fundamental insights about black hole mechanics. The theorem
predicts that the total area of a black hole's event horizon — and all black holes in the universe, for that matter — should never decrease
.
What is Stephen Hawking's greatest achievement?
Professor Stephen Hawking had researched his whole life the basic laws governing the universe. In fact, he was the first to elaborate an equation to try to
unify general relativity
and quantum physics, a ‘theory of everything'. This equation is called the temperature formula of a black hole.
What did Hawking accomplish?
Stephen Hawking worked on
the physics of black holes
. He proposed that black holes would emit subatomic particles until they eventually exploded. He also wrote best-selling books, the most famous of which was A Brief History of Time: From the Big Bang to Black Holes (1988).

What is theory of black hole?
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.
The theory of general relativity
predicts that a sufficiently compact mass can deform spacetime to form a black hole.
What was Einstein's theory on black holes?
Over a century ago, Albert Einstein predicted that
the gravitational pull of black holes were so strong that they should bend light right around them
. Black holes don't emit light, they trap it; and ordinarily, you can't see anything behind a black hole.
What's inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually
a lot of matter condensed into a single point
. This point is known as a singularity.
What is the greatest invention of Stephen Hawking?
Hawking's scientific works included a collaboration with Roger Penrose on gravitational singularity theorems in the framework of general relativity and the theoretical prediction that
black holes emit radiation
, often called Hawking radiation.
What was Stephen Hawking last words?
Stephen Hawking's last words aren't known. The final sentence in his last ever book was “Unleash your imagination. Shape the future.” These were the final sentences in his book Brief Answers to Big Questions. The last words of his final public appearance were “
My motto is there are no boundaries.
”
How did Hawking radiation change the world?
In 1974, Hawking showed that, under certain conditions,
black holes actually could create and emit subatomic particles, eventually dissolving and finally exploding in an intense burst of energy
. In other words: Black holes were not completely black after all.
