The number one strength of the big bang theory is the reliability of the
predictions this model makes about observeable phenomena. The most
significant confirmation of a prediction that follows from the big bang
model was the discovery of the cosmic microwave background (CMB). The
concept that a pervasive "glow" from a very young, very hot universe should
still be observable has been around since the 1940's. The 1965 discovery by
AT&T Bell Labs researchers of the CMB confirmed this prediction and provided
strong support for the big bang model. There are other predictions of the
big bang which have been confirmed by observation--chief among these is the
observation that the universe is expanding--and it is this power of
prediction that makes the big bang the most compelling model for creation of
the universe.
