Black holes are cosmic phenomena with gravitational forces so strong that nothing, not even light, can escape. At their core lies the singularity, a point of infinite density. The event horizon marks the boundary beyond which information is lost to the observable universe. These objects are key to understanding spacetime and are predicted by Einstein's theory of general relativity. Advances in technology have allowed us to observe black holes directly, confirming long-standing theories and challenging our understanding of physics.
