How do we know the universe has a beginning?
Observational evidence to confirm the idea that the universe had a very dense beginning came in October 1965, with the discovery of a faint background of microwaves throughout space. The only reasonable interpretation is that this “cosmic microwave background” is radiation left over from an early hot and dense state.
How did the universe begin from nothing?
Virtually all astronomers now believe that the universe sprang forth in what is known as the “Big Bang” explosion, from a state of extraordinary compression and phenomenally high temperature in which forces such as gravity and electromagnetism were unified in a single, all-encompassing force.
Who theorized that the universe had a beginning?
A Belgian priest named Georges Lemaître first suggested the big bang theory in the 1920s, when he theorized that the universe began from a single primordial atom.
