A general comment about this thread rather than a reply to Khorton in particular: The original post didn’t suggest that this should be a brainstorming thread, and I didn’t interpret it like that. I interpreted it as a question looking for answers that the posters believe, rather than only hypothesis generation/brainstorming.
When I was studying maths it was made clear to us that some things were obvious, but not obviously obvious. Furthermore, many things I thought were obvious were in fact not obvious, and some were not even true at all!
