BLACK HOLE

Markonah_7

A black hole is a region of spacetime where gravity is so strong that nothing, including light or other electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.



Who invented 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 inside the black hole?

Black holes have two parts. There is the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape. And then, at the center, is the singularity. That's the word we use to describe a point that is infinitely small and infinitely dense.

Who can survive a black hole?


No material that falls inside a black hole could survive intact. Unfortunately, because nothing can escape a black hole's event horizon — not even information — we'll never know for certain what happens when matter falls past the point of no return.
