Big badda boom!
ETA: Maybe we'll see those attack ships in fire... |

Neat stuff. Love your passion.
I kept reading it as “Beetlejuice” |

Pardon my ignorance, but wouldn’t it have already gone supernova and we just have not seen it yet? It would take 70 yrs for that light to get here?
|
|
If it is 700 light years away, wouldn't that mean if this event happens that it actually has already happened but what we actually see is delayed by 700 years ? So this fucker might have already gone supernova and we don't even know it?

I wonder how long it would shine brighter than the moon? A few years of a second moon would be pretty sweet I could tag out on deer every year.

View Quote It possibly could have went supernova back before Columbus sailed. 1 light year = the distance light travels in one year. So if it is 700 light years away, that light is already 700 years old once it reaches our eyes. |

If I recall correctly, the Crab Nebula is about twice the distance as Betelgeuse.
It would be amazing to see, but it could cycle for thousands more years. The Bayer designation is Alpha Orionis, which suggests that in the last few hundred years it may have been brighter than Rigel, which got the designation of Beta Orionis, despite it being dimmer than Rigel today. Often Bayer used the brightest star for Alpha, but not always. Sometimes he used position in the constellation as well so that's just a working theory. It's a theory that I think has merit. |

Pretty interesting, it's the closest star of sufficient mass to go supernova.
And yes, there is a pretty good chance it already went boom and we just can't see it yet, due to distance and the speed of light. edit: Torf made me question myself and I went back and looked up the shit I read a while ago. Looks like Betelgeuse is the closest star that is definitely above the mass limit for a type II supernova (the big booms). There are four stars closer (IK Pegasi, Spica, Alpha Lupi, and Antares) that are big enough for at least a Type I supernova, but since the mass needed for a Type 2 is uncertain (between 8 and 15 stellar masses), none of these are over the upper limit. |

It would be uber-cool if it did supernova & Orion was changed—that’s truly a “once in a human lifetime” moment.
I never got to see any A-bombs nor H-bombs tests, even after nagging my dad to go before they stopped—i think this would be almost as cool. |

That could really screw things up here on earth. Many plants and animals have cicadian rhythm. If it is too bright at night during the summer corn crops could fail, among others.

It may have already gone supernova, now how long before we see it

Is this something we need to start digging bunkers for or walking into the yard and staring at?

That would be incredible.
I'm jealous of past mankind that got to witness a supernova. I wonder what they thought about it being they didn't have the knowledge of the cosmos like we do today? |

The stars are fake Satanic hologram designed to trick arrogant "scientists".
Prove me wrong, science boys. Bring Mr Higgs on! |

Possible though the odds . Time just hits different when on this sort of topic. As mentioned, 700 years for us to know it happened back around the 1320s...100 years war was ongoing and I don't think the plague had even happened yet, iirc.
Let alone that star has been "dying" longer than our species has existed. Would be absolutely amazing to see nonetheless |

Wouldn’t that mean that it already happens like 650 years ago and we just haven’t seen it yet?

But the point of relativity is not exactly that "we just have not seen it yet" but that there is no way for us to know about it yet. It's not so much about the limitations of the speed of light showing us something but how fast information can be transmitted. |

View Quote In my opinion, which is not the best informed but is well informed from my perspective, it has already happened and it is more likely to be apparent to us sooner rather than later (that is more likely we'll see it withing 70 years than 700 years), but it is hard to tell since we have so few well-observed cases. |
