Thanks for the beauty, it feels good.
Some thinking out loud. I can’t help but feel that the key is in the successive layers of maps and territories : maths is (or contains) the map of which physics is the territory, physics is the map of which ‘the real world’ is the territory, ‘the real world’ is the map our brains create from the sensory input concerning the territory which is the ‘play of energies’ out there, while that in itself is another map.
Antony Garrett Lisi’s proposal, as an example, would be the most elegant meta-map yet.
What these maps have in commmon is : being created by the human brain, a wet lump of nervous tissue comprising ad-hoc purpose specific modules. It has specific ways of making maps, so small wonder all these layers of maps are coherent. Now if the ‘mathematics’ layer of maps has unforeseen and self-consistent properties, it could be just a manifestation of the nature of our map-making modules : they are rules driven.
So, is the Universe a geometric figure corresponding to a Lie E8 group, or does that just happen to be the way the human brain is built to interpret things ?

Yeah but, science works. Ergo math works. See also.
