Quoted: Is it? I think it's the closest candidate for supernovae in our lifetime, but I think there are closer stars which have the necessary mass, just not as far along. View Quote View All Quotes View All Quotes Quoted: Quoted: Pretty interesting, it's the closest start 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. @torf You 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. |

Quoted: 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? View Quote yes looking at the stars is looking into the past, even if you look up at our sun that is still seeing it how it looked over 8 minutes ago. Nothing in astronomy is realtime. Space is fucking huge |

are we taking bets on when she'll blow? people thinking it'll happen any day now have no grasp on the odds of it happening "soon" (people time) vs cosmic time scales. i'd like to take advantage of that

Yes, Spica and Antares were two that I was thinking could also hit that magic threshold. Reading about stellar evolution is a very interesting topic for me. Part of the mystery is the great distances and timespans involved. It makes measurements and data gathering difficult. |

If it blows right this second it will take 642.5 years for humanity to see it.
None of us are going to be entertained. Unless it blew up 643 years ago. Then we will get the show in 6 months. |

The mechanisms are different for a 1A & 1B (screw using Roman numerals with phone text.) vs 1c (Wolf-Rayet stars) and the various Type 2 candidates like Betelgeuse. 1A, there's a close orbiting star pair, one of them a white dwarf that steals stellar material from the other star. More material, more heat and fusion, but it doesn't restart gradually, but rather all at once past a given mass threshold. A star is a balance between a lot of fusion energy pushing the star outwards, and a lot of gravitational potential energy trying to pull everything together. Run out of fusion, and everything rushes towards the core, really really fast. Type 2s, the star runs out of stuff to burn---it takes more energy to fuse iron56 than you get when you do---the mass of the star slams towards the center, big badaboom, and some of the energy from which creates elements like gold and uranium. The rest comes off as a really bright light and a staggering number of neutrinos. Betelguese is actually thought to not be exploding anytime soon---though the theories keep changing with more data---and when it does go boom!, it'll be something like -8 to -10 magnitude. Pushing Full Moon brightness for a few.months, IIRC. Brighter than the Crab Nebula boom, because Betelgeuse is a whole lot closer. No GRB (at us) is expected. Contrast with the Pinwheel Star, WR-104... |

Quoted: You're going to feel a bit retarded when you figure out what a light year means. If you had a telescope aimed right at it and saw it go boom, that didn't actually happen while you were watching. It took 700 years for the light you are seeing to get to us, it happened 700 years ago. When you are looking at stars in the sky, you are basically looking at a time machine of the past. When you look at that star, you're actually seeing what it looked like 700 years ago. It might have turned into a giant vagina right now but we wouldn't see that for 700 years. Likewise if you were in your gay pink spaceship right next to it when it went supernova, it would take 700 years for anyone on earth to see that happen. It's similar to the speed of sound, in that if you hear a gunshot two miles away, that person didn't pull the trigger right when you heard the shot. The sound has to travel to you. It had already happened about 10 seconds ago and it took that long for the sound to travel 2 miles. View Quote I know what a fucking Light Year is. You completely missed the point. |

When it blows then a neutron star will be 500 plus light years from our solar system and the third closest after J185635-3754 at 400 light years and PSR J0108-1431 about 424 light year.
Thankfully J185635-3754 does not pulsate and PSR J0108-143 is a faint pulser. Will we be as lucky with betelgeuse's neutron start? They younger they are the more they pulsate and give off gamma ray bursts. |

View Quote The axis of rotation for Betelguese is not thought to coincide at all with the Solar System. It's thought that neutron star rotational axis direction should, through conservation of angular momentum, be fairly close to the parent star's As relativistic jets and associated gamma ray burst phenomena are thought to lie along the axis of rotation, neither Betelgeuse, nor its stellar remnant, should be an issue. The above is definitely not the case for WR-104 that I mentioned in my previous post. |

How does that double slit experiment with light waves/particles being observed, not observed and behaving differently fit into the equation? |

It would be a cool sight. I believe ancient humans made drawings of a "second Sun", which was likely a nearby supernova. It likely lit up the sky for weeks or a few months.

Most likely Wan-To is inhabiting it, sucking out all its energy.
He'll move out before it goes boom though. Or did, 700 years ago. |

Quoted: The James Webb telescope can look back in time. Couldn’t they see if this thing blew already? Shit like this is weird and awesome. View Quote Oh good grief. I thought Reddit had some questions. All telescopes “see back in time” because the light they receive come from a far away source. Light has a finite speed in a vacuum. Betelgeuse is 548ly away give or take so what we see happened 548 years ago. So in essence all telescopes see back in time. How far back is determined by how far away the observed object is. If the JW looks at a distance galaxy it could be looking back billions of years. Guess what? If you look at Betelgeuse with your eyes you are looking back in time because those photon hitting your retina left the star roughly 548 years ago. When you look up at our sun, you are looking back in time about 8 minutes and if you look at the moon you are looking back in time about 1.5 seconds. What we perceive as instantaneous in our eye at the end of your fingers isn’t exactly at the time we perceive it. Crazy but true. Our brains adjust for the time adjustment. Attached File A light year is roughly 5.88 Trillion miles. 186,000 miles a second. Stated in miles for GD. |
