The theory in the thread title, the general theory of stellar metamorphosis.
Oh and here's some back up from the people who support big bang creationism:
"The question of 'the beginning' is as inescapable for cosmologists as it is for theologians...there is no doubt that a parallel exists between the big bang as an event and the Christian notion of creation from nothing." -George Smoot, 2006 Nobel Prize in Physics for discoveries related to the cosmic background radiation / big bang
"the universe was created out of nothing...and one which has an underlying, one might say 'supernatural' plan." -Arno Penzias Nobel Prize for Physics in 1978 for discovery of the cosmic background radiation of the 'big bang."
"It would be very difficult to explain why the universe should have begun in just this way, except as the act of a God who intended to create beings like us." -Stephen Hawkins, a Brief History of Time
"The essential element in the astronomical and biblical accounts of Genesis is the same: the chain of events leading to man commenced suddenly, at a finite moment in time, in a flash of light and energy... is one of the main supports of the scientific story of Genesis." -Robert Jastrow, Astronomer, First chairman of NASA's Lunar Exploration Committee
The quotes kinda show that big bang is religion disguised as science.
