My Scientist Friend: The borderland between math-phys & pure math is rich with strange beasts – like the amplituhedron … etc

And the approximations that work so astonishingly well in calculus – at both the infinite & infinitesimal – is some sort of clue hidden in plain sight.

If multiple U-s turned out to exist – as math suggests – then I would bet math is true in all of them …

Which in turn strongly suggests that evolution /survival of the fittest is NOT the most fundamental — too bad for the Thrasymachians…

Me: It would be challenging for me to determine how to agree with you more emphatically…
