Answer 2

Einsteins laws of General Relativity suggest that a static universe is only possible when you add a cosmological constant to the equations. Without that the universe has to expand or contract. Edwin Hubble noticed that all galaxies where moving apart. Georges Lemaître proposed the theory of an expanding universe. He also proposed that, rolling the movie backward in time, the universe becomes smaller and smaller and must have started with a “primeval atom”. thus big bang theory states that the whole universe was created due to the results of a supernova explosion called the big Bang.
