For Pete's sake, Thomas, did you not know that big bang cosmology is dominated by mathematicians, trying to push their favourite mathematical objects? Here's one of them, but there are others (such as Calabi-Yau):
Metric expansion is a key feature of Big Bang cosmology, is modeled mathematically with the Friedmann-LemaƮtre-Robertson-Walker metric and is a generic property of the universe we inhabit.

BTW, I'm not interested in your angry questions about minor details.
Oh, and then there's the "particle physics as cosmology" people, with symmetry group E8, etc.
