Is there an argument for this rather than the other way?
I’m probably misremembering, but I thought I’d seen something about spacetime being continuous and particles being braids in that aether — but did that blow up when string theory didn’t happen at the LHC?

- gpderetta 4y agoAFAIK non-stringy quantum gravity theories have been proposed.
