We
pretty much know for sure that the universe was once extremely small,
and extremely hot. And we know that something set it in motion,
expanding rapidly and continuing to do-so today. But the actual moment
of ‘the Big Bang’ is still a bit of a grey area within physics. The
theories of general relativity and quantum mechanics disagree on this
pivotal “beginning of time,” and physicists continue to search for an
all-encompassing theory to unify the study of our universe. On this
week’s Space Time, we begin to discuss the current state of the Big Bang
Theory, and where it could go from here.
