What will happen if Betelgeuse explodes?

Betelgeuse's pole isn't pointed in our direction.
>ensuing relativistic jet
Relativistic jets come from active galactic nuclei, black holes and neutron stars. Not red giants.

Hypernovae produce powerful gamma ray bursts, perhaps that's what you're asking about?
Betelgeuse isn't a massive hypergiant, so it won't produce a gamma ray burst. It's a red supergiant, and will explode like your everyday supernova, a spherical explosion that will have dissipated into oblivion by the time the thin ass shell hits the solar system, if it ever does.

Betelgeuse will not cause us any harm. It'll be a pretty sight, brightness comparable to the full moon. It'll stay bright for a few weeks, maybe a month.

How can you be so sure?

Did you not read the rest of my post? Even if it was pointed at us, literally nothing would happen.

Betelgeuse is large and close enough that you can actually directly image it and study its rotation and activity to determine where the poles are.

Someone award this guy the Nobel Prize for solving an "unsolved problem in physics" on 4chan

Why are you replying to my post twice?

How is that an unsolved problem? Relativistic jets don't come from red giants. That's a known fact.

>ALL RED GIANTS DON'T DO RELATIVISTIC JETS

>>8308521
Read about relativistic jets and before claiming it has an unknown origin.

>>8308523
Maybe he's thinking of Gamma ray bursts, those have pretty much unknown origins

>>8308527
Yes, I asked him earlier if he meant gamma ray bursts.

newfaggot here.

What is Betelgeuse and why woud it explode.
And if it explodes, is this guy correct ? : >>8308506

Both Betelgeuse and Rigel have used up all of their hydrogen and are no longer main sequence stars. The cosmic contact says Betelgeuse is still stable and we'd better watch the 'foot' and that a supernova closer than 2000 light years effects genetic modifications..

The the future where this has already happened it doesn't really matter.
