...Into The Realm Of Science
In 1929 Edwin Hubble made the landmark observation that wherever you look, distant stars are moving rapidly away from us. In other words, the universe is expanding. He also reasoned that about ten or twenty thousand million years ago, all the stars must have started from exactly the same place.
Hubble's discovery brought the beginning of the universe into the realm of science. Hubble also suggested the big bang, an instant when the universe was infinitesimally small and, therefore, infinitely dense. If there were events earlier than this, they could not affect what happened afterward.
