- THE BIG BANG THEORY IS BORN
-
- In 1924 the Catholic priest, Georges Lemaitre, proposed that the universe began from a small primeval atom which
- exploded and started expanding in retarded velocity until the expansion would stop, only to continue later with
- increasing speed. Lemaitre's model lead to the idea of the big bang.
-
- In 1923 the American astronomer Edwin Hubble (1889 - 1953) noticed, while studying Andromeda, that it is a faraway
- galaxy, not a distant star in our Milky Way.
-
- With Hubble's discoveries the Milky Way lost its position in the universe as the unique central galaxy and as well the
- Sun's position became still more modest.
