- TL;DR Summary
- No symmetries in the universe at the Big Bang...?

I apologize in advance if this is a stupid question but...

According to some scenarios about the beginning of the universe (namely cosmological inflation), in layman's terms, everything was born out of a quantum fluctuation which caused a violent expansion. In this case, since an expanding universe breaks the time translation symmetry, energy conservation does not necessarily hold and therefore energy and matter could have appeared from """nowhere""" ()

However, if these conditions were "repeated" in a spacetime with no (global) symmetries, could all conservation laws and the rest fundamental laws of physics have been also violated or approximate? Would this be theoretically possible?
