Physics by way of the cable company
From a whipping-up-anxiety article in Time magazine titled “Will the Earth Have Two Suns by 2012?”
Regarding Betelgeuse, a rapidly collapsing red super-giant star:
“It goes bang, it explodes, it lights up,” Carter said. “We’ll have incredible brightness for a brief period of time…and then over the coming months it begins to fade and then eventually it will be very hard to see at all.”
And while the celestial event could take place before the end of 2012, it may not occur for a million years.
Emphasis added by me.
Sooo, it could happen in a year or a million years. Trifle hard to plan provisions for that million year stretch. What’s the half-life on my water container?
It’s only January of 2011 and I’m seriously DONE with the doomsday predictions.
Meanwhile, a star that explodes and lights up the Earth for a few weeks then fades away? That’s pretty damn cool. I kind of hope it happens by 2012.
