Our understanding of the universe changes all the time as we gain more information. I find this rationale approach very good, but it can also be really frustrating when debating the origins and composition of the universe with someone who takes theories as "categorical" truths.

This seems to be specifically about our understanding of the expansion of the universe (from the big bang).

It also throws a wrench into "there is no center, expansion is the same everywhere."
