quip - Take mathematics which governs our universe (the closest we have to an absolute) cannot ultimately be proven to be true. Are you familiar with Gödel's incompleteness theorems?

Mathematics models some very limited aspects of nature well; governing nature is a bridge too far, imo.

Also Gödel's incompleteness theorems show that not all truths can be proved; NOT that no truths can be proved (a huge difference). Anyone who has taken high-school geometry should be aware of the latter part.
