Black hole

A black hole is a region in space where?the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space.

This compression can take place at the end of a star's life. Some black holes are a result of dying stars.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.

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. In 1916, Karl Schwarzschild found the first modern solution of general relativity that would characterize a black hole.
