- TL;DR Summary
- Consequences of the absence of global symmetries...?

I found some interesting discussions in this site (e.g: https://www.physicsforums.com/threads/smolin-lessons-from-einsteins-discovery.849464/; https://www.physicsforums.com/threads/relatismo-to-the-max.83885/) which are related to Lee Smolin's ideas that laws are not immutable and can therefore change in time (even the most fundamental ones).

I've seen Smolin's idea about laws being able to change with time is related to his idea that there are no fundamental global symmetries (and therefore they are emergent or approximate, contrarily to what is believed by most physicists working in the "unification program" where one would expect to find more and more symmetry in higher energies) (https://www.physicsforums.com/threa...se-that-symmetries-are-emergent.995027/page-2).

Therefore, if the universe had no global symmetries would this mean that all laws of physics (even the most fundamental ones) and fundamental symmetries like the Lorentz or CPT invariances would not be fundamental and unchanging but rather emergent, approximate and with the potential to change in time

__(at least in a cosmological scale)__?
