Gamow’s “Giant” Theory

Gamow’s "Giant" Theory proposed that the universe originated from a colossal, dense "primeval atom" or nucleus—think of it as an enormous, hot, primordial seed. This super-atom contained all the matter and energy universe has today. About 13.8 billion years ago, it suddenly exploded in a "big bang," initiating cosmic expansion. The theory helped explain how the universe evolved from an initial, concentrated state into the vast, expanding cosmos we observe now, laying foundational ideas for modern Big Bang cosmology.
