The Big Bang is the dominant cosmological theory that explains the origins of the observable universe. Who was the first scientist to theorize about it?

In the 1920s, a Belgian priest named Georges Lemaître proposed the Big Bang hypothesis, suggesting that the world started with a single primordial atom. The theory got a significant boost from Edwin Hubble's discoveries that galaxies are speeding away from us in all directions.
