The Full Story
Belgian priest and physicist Georges Lemaître proposed in 1927 that the universe is expanding and may have begun from a single dense state. He called it the “primeval atom,” a concept now recognized as an early formulation of the Big Bang theory. Lemaître’s work connected Einstein’s equations with astronomical observations. Later evidence such as the cosmic microwave background strengthened the model. Today the Big Bang is the standard explanation for the universe’s origin and evolution.
