Hey not here to talk about any of the weird consciousness stuff, just science, came back to this thread because I was interested in what you were saying about relativity. Like aren't event horizons as found in black holes and the cosmic horizon the same thing?
It's my understanding that it's not possible to synchronize two clocks without bringing them together. And regardless if two clocks are separated by an event horizon (i.e one of them fell into a black hole) or if they're separated by the cosmic horizon (i.e one is outside the observable universe) they can't ever be brought together. Doesn't that mean you can't meaningfully define a moment in time that is simultaneous for them?
Like in the case of a clock inside a black hole, that's in the infinite future of another clock outside the black hole, right?
