    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.

        That depends. The chances of finding other life are lower. That would also make a cosmic horizon that we would never be able to see beyond. It would make us unable to find the beginning of everything.

          Those are all really interesting factors to consider and I appreciate the response!

          I’ll come clean, when I wrote it, I was just making a funny, like… A “decaying vacuum” would suck less over time. . .than a black hole. Lol XD

          To your point though, less likelihood of finding other life is such a wildcard, for sure. (Less likelihood of meeting cool benevolent spacefarers…but also less likely to be spotted by something like Mass Effect’s Reapers, or accidentally bring home Xenomorphs or extragalactic pathogens lol)

          And…not being able to ever see the beginning of everything…my curious mind says that’d be such a bummer but also…oddly beautiful? I’ll have to ponder that…

            Frankly, I’d love to be able to explain how the universe started. That would be the final nail in the coffin for religion.
