Whose idea first explained how galaxies can form from tiny early-universe fluctuations?
Quick Answer
George Gamow helped develop the early hot-universe picture and the idea that matter from the early cosmos would seed later structure. His work influenced modern structure formation theories.
The Full Story
George Gamow was one of the pioneers of hot Big Bang cosmology. In the late 1940s he and collaborators explored how the early universe could synthesize light elements and evolve into the structured cosmos we see today. While later theories refined the details, Gamow’s work helped frame the question of how small early irregularities could grow into galaxies and clusters. His ideas remain historically important in cosmology.
