Checks the sky. No it hasn't happened. So it's either not happened yet or events of your post and Betelgeuse going supernova are separated by spacelike interval

Checks the sky. No it hasn't happened. So it's either not happened yet or events of your post and Betelgeuse going supernova are separated by spacelike interval and as such they do not belong in before-after relation.
"It hasn't happened" = it's not in our past light cone. "It's not happened yet" = it's in our future light cone.

- dreamcompiler 7y agoFair enough. There's no such thing as a universal now. I should have said "No information about a supernova event has reached us."
