Introduction to the big-bang theory
In 1929 Hubble observed that, regardless of in which direction we look, galaxies are moving away from us at speeds proportional to their distance from us. This observation, coupled with the discovery of the cosmic microwave background radiation (CMBR or CMB) in 1965 by Penzias and Wilson, has led to the conclusion that the whole universe is expanding.
Reasoning backwards from this, many physicists and cosmologists have further concluded that the whole universe must have been contained in an infinitely curved, infinitely massive singularity that exploded in a big-bang that became the universe as we know it today. This is the big-bang theory.
While the two observations of expansion and cosmic background microwave radiation do strongly support the idea that the part of the universe we live in was smaller and much hotter than it is now, they would also be what was observed if the whole universe that is visible to us now was just the result of a very large super nova that took place in one tiny corner of an infinite universe.
