Black Holes

A black hole is a region in spacetime where gravity is so intense that nothing, not even light, can escape its pull. This extreme gravitational force is a result of a massive amount of matter being squeezed into an incredibly small space.

The concept of an object in space so dense that it traps light was first proposed in the 18th century. However, it was Albert Einstein's theory of general relativity in 1915 that provided the theoretical framework for the modern understanding of black holes.
