Black holes could be the key to a quantum theory of gravity, providing a deeper understanding of how reality, space, and time works. They are regions of space from which even light can't escape, and have fascinated physicists since their theoretical predictions, which date back to the early 20th century. The existence of black holes forces physicists to think about both quantum theory and general relativity together, highlighting the need for a unifying theory or quantum gravity.
