I thought this was about Bernie. NM.

It is a nitpick. We all know the facts of interstellar distances. Its just convenient shorthand to say it could explode any day now rather than the more awkward the explosion could have happened such that its light could be arriving any day now.
And BTW (nitpick alert) its 640 light years away, not 700.

So, anytime between 700 years ago and 100,000 years from now something might happen.
Where can I get a job where someone else pays me to set around and study crap thats never gonna happen or if it does it wont have any effect on humanity or it will be so massively catastrophic there wont be anything you can do about it?
Im good at that kinda crap!

642.5 light years, says Wikipedia.

Did Mr Wright not take physics? Special relativity answers this question:
- You probably can't travel at the speed of light without using infinite energy to get there. Suppose you are traveling 1 mph less than the speed of light.
- An outside observer sees the beam of light moving away from you at 1 mph (relative to your car) but 186,282 mi/sec relative to himself
- You see the beam moving away from at the usual speed of light, 186,282 mi/sec
Wrapping your head around that result leads to all sorts of odd conclusions, like the one that says the fixed observer would see the clock in my moving car running much, much slower than his.

Good, one layer of protection via theory. Do we know, as a second layer, the orientation of its poles well enough to say it wouldnt be pointed at us if the first theory were wrong? That much angular momentum is very unlikely to change its aim.

Seriously? Let’s see if I can explain it this way... Okay, Steven Wright is a comedian. He tells jokes.

Well, they have been able to get details of Betelgeuse’s surface using speckle interferometry, and one of the brighter spots is thought to be its pole. This is off center, so not pointed at us. But I doubt Betelgeuse is about to supernova anyway. I’ve heard another theory that it may have absorbed another star as it expanded into a supergiant, and still has plenty of fuel for another few million years. But you can never really be sure.
To: Mark17
Yes. It could have exploded 699 years ago and we will see it next year.

Interesting idea. If true it has about 6 months until the silicon-burning phase, and then boom. If SN1987A was any indication, the neutrino front precedes the light curve by 2 to 3 hours.

It's like waiting for Ross and Rachel. :^)
