There is no known relationship between dark matter and dark energy. They could have been called unknown matter and unknown energy! The absence of a good account for each does not infer a relationship between the two.

Sorry, I should have clarified: I mean I would spend all my days doubting the mathematics, rather than doubting the physical universe. If that makes sense? Of course all of mathematics can be argued to have a physical sort of root.

You cannot choose your allegiance and stick with it. The reality is that there is always various types of evidence to contend with.

Chances are if you were a physicist/cosmologist you would be of the same opinion as the majority because you would be exposed to just about the same evidence.
