3/ A paper came out a few years ago putting Betelgeuse going supernova in about 100,000 years. So it’s unlikely to be ready to go off now.
5/ The amount the day changes and the times of sunrise/set depend on latitude (and your local horizon). You can check that here: Don’t forget to put in your own location; that’s for Boulder.
8/ At 650 light years away it’s too far to hurt us even if it does go supernova. It’ll get as bright as the full Moon though! That’ll be cool (though irritating for astronomers who want to observe other objects).
This is real: 11 Oregon GOP senators have fled, and one is threatening to kill police officers, because *they don’t want to vote on a carbon tax*. This is what science denial and fossil fuel graft have brought us to. This is what we must fight if we want to save our future.
