Space time is so strange. If it has "happened already," but the change hasn't propagated to us yet by the speed of light, has it really "already happened" in any actual way?

Yeah, I was actually thinking about this the other day, it's so strange. There is no objectivity in physics and every perspective is equally true, so Betelgeuse is both alive to us on Earth, but also could be already dead to some other life closer to it. It's like trying to imagine a 4th (or 5th, depending on how you look at it) dimension, I just can't wrap my head around it
