Yes-and it means if it exploded it could have done so in 1330 and we wont know it for another decade. But-if it does happen-it will not be good if its pointed this direction.
But if it exploded in 1310 we saw it 10 years ago and I do not remember that.
Unless Betelgeuse is only 470 light years away in which case it might have happened in 1550 and that means IT IS HAPPENING TO US RIGHT HERE RIGHT NOW. It is time to panic!!
Do super novas point? I didn't know that. I am going to hide behind a tree for a while.
