Hawking’s Tiny 1974 Paper: Black Holes That Could Explode

In 1974 Stephen Hawking published a short Nature paper proposing that tiny primordial black holes, formed in the early universe, could evaporate and explode via Hawking radiation, flipping the view that black holes only grow. The idea, which connects quantum mechanics to gravity, later sparked the black hole information paradox as it suggested information might be lost; Hawking and collaborators’ later work proposed mechanisms for information escape, including wormholes, though direct evidence remains elusive. Ongoing research, including gravitational waves and James Webb observations, continues to investigate primordial black holes and their potential cosmological signatures.
