in college i took a class on special relativity and did more poorly than i wanted to and felt vaguely bad about it and i think that might be why i haven’t made any attempt to learn relativity since even though i grew up reading about it constantly

really weird how even in QFT the manifold structure of spacetime is just taken for granted
feels to me like it should be emergent / derived for the theory to be “truly quantum” or something?
is this what the spin foam ppl do
Replying to
Ooh good question, I'm not sure. That would be appealing, but I'd never made that connection before (I had still pictured the foam "filling" space rather than generating it?)

just skimmed a spin foam paper and yeah i think this is what the spin foam people are doing, neato
