- TL;DR Summary
- Could somehow the fundamental laws and symmetries of physics change or be broken?

There are some theoretical processes (like vacuum decay in quantum field theory) that could change the physical constants of the universe. Similarly, in inflation theory, various models predict that multiple regions that would stop inflating would become "bubble universes" perhaps with different constants of nature. Something similar happens with string theory landscape of vacua...

But could there be any process that would fundamentally rewrite every fundamental law that we know? Any process that would break every symmetry and law of physics that we can think of and just absolute randomness and chaos would govern? Perhaps, and this is just a gedankenexperiment, a situation where an infinite amount of energy exist or where there is an infinite amount of energy density could do it?
