Question

The astronomer who first worked out the mathematical description of black hole event horizons was?

Answer 1

Karl Schwarzschild devised the first general relativity model that would adequately describe a black hole in 1916.

What is Black Hole?

A black hole is an area of spacetime with such intense gravitational pull that nothing can escape from it, not even light or other electromagnetic waves. According to general relativity theory, a compact enough mass can bend spacetime into a black hole. The event horizon is the line beyond which there is no escape.

Black holes were once thought to be a mathematical curiosity, but theoretical research in the 1960s revealed that they were actually a general prediction of general relativity.
