Which scientist predicted the existence of black holes through relativity?

Albert Einstein’s theory of general relativity predicted the possibility of black holes, but it was Karl Schwarzschild who first discovered the mathematical solution describing such a region. His calculations showed that a massive star could collapse and form a black hole, an object with a boundary called the event horizon. Although Einstein himself was skeptical about the physical reality of black holes, Schwarzschild used his equations to demonstrate their existence. Over time, more scientists explored Einstein’s theory, leading to the acceptance of black holes in astronomy and physics.
