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

We don't actually know how far away Betelgeuse is: it could be 500 light years away; it could be just around the corner getting a pack of ciggies and a six-pack to watch the footie on the sky box a bit later, yeah? Come around six, I'll get the missus to defrost a pizza and we can talk fantasy football. The parking might be a bit shite, but the neighbour's away this weekend, so just use their driveaway and pop a "soz" letter through their door just in case. Also, ask Suze if her brother still fixes boilers as ours has gone up this week and it could use a look-see, cheers. If you see the bailiffs outside, tell 'em to get bent.
