    What if we’re not in a black hole, but in the aftermath of a vacuum decay event?

        Look up vacuum decay. It’s theoretically a thing that can rewrite spacetime at a lower energy level, and would expand out from a point in a bubble. The expanding bubble would erase and rewrite everything it touched into the lower energy level.

          Yes I know what vacuum decay is, and the thing I referenced, the inflaton field, is a hypothetized false vacuum near the very start of the universe, that went through this exact process, giving rise to our current vacuum and ending the hypothetized inflation era

          I know there’s a hypothesis that our current vacuum could be metastable as well, but that’s a seperate thing

            Yeah, I believe the Higgs field showed us to be metastable, unless new findings have invalidated that.
