Just watched a Tibees video about the possibility of a force like gravity potentially traveling through folded 4D space and affecting something before the light can reach it.
I realize this sort of thing has been thoroughly tested and debunked, but I can't get it out of my head. What if it's some force other than gravity? What if Earth just happens to be folded against some empty bit of space - and what if that were to change?
Like, I've thought about folded spacetime before, but always in the context of traveling between points (like the classic ant-on-paper thought experiment). I never really considered that something could in theory radiate a force (like gravity) in 4+ dimensions.
Maybe you've seen this already, but if you haven't, here's a wonderfully terrifying thought:

An interesting read, no doubt, but I still disagree with
The "threat" here would entail no negative emotions, no human (or other) suffering, just... nothing. Plus, it sounds like if the universe were indeed unstable/meta-stable, there's nothing we could change about it anyway. So of all the things I can worry about, I feel this deserves the least amount of worry.
