Quote HistoryQuoted: Wouldn’t that mean that it already happens like 650 years ago and we just haven’t seen it yet? It could mean that it happened last week and our great great great great great grandchildren will die before the event is visible. We are trying to make assumptions and calculations for time lines measured in millions of years, based on the observations of a few thousand years. There's bound to be a few miscalculations here and there. |

I saw Halley's Comet in 1986. I found it underwhelming. Hale-Bopp in 1997 was pretty cool.

Quote HistoryQuoted: 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? Indeed it does. |

Quoted:If it did go supernova, this will be the first "close" star to go supernova since the the star that created the Crab Nebula went supernova in 1054. That supernova was so bright, it was stated that it shined during the day and was many times brighter than the full moon at night. By "close", Betelgeuse is around 700 light years away, so it is far enough to not be a danger, but close enough to greatly outshine our moon if it ever does go Supernova. 1054 and that supernova led to what again? Remember your history ... it shone for 23 days and was seen all over the world. Leo the IX croaked and that led-to ... The Great Schism ... because that Super Nova was a sign. It changed future history dramatically. Not only that but William the Conqueror had his first vision in 1054, after seeing that super nova, which motivated him to eventually lead the Norman Conquest 12 years later. Let's hope there is equal shtf if Betelgeuse blows in our lifetime. I've been following it pretty closely since it dimmed. I fully expect it to be visible in my lifetime and I don't have that many years remaining. What will be interesting is if it goes supernova and/or turns neutron or black hole (like M101 did yesterday) and it starts spewing jets in our direction. |

Quote HistoryQuoted: your laughable decades mean nothing to that star. it's thousands of years away from ending Bullshit, it's very close and will kaboom in the blink of an eye. That is hundreds of thousands of years in cosmic eye terms. A recent study came out that supernovas are more damaging than previously thought. But Betelgeuse is still far enough away that the Earth should live. Yay. |

There's bound to be a few miscalculations here and there. Not exactly. We've only been able to make precise observations for a few thousand years, but we can see back in time by billions of years. So, actually, we have visibility over a much longer time period than the brief time humans have had telescopes. |

IMO 700 LY is too close for comfort.
If we're seeing the beginnings of star death, what kind of ejecta might be headed our way? Flickering light is getting here now. Suppose it went full nova 699 years ago and some sub-C(but not sub enough to be a problem for our great-great-grandchildren--it's OUR problem) materials, or refugees, start arriving in the TOO near future. We could be doomed. That tic-tac might be a forward scout for the Visitors to come, heading our direction just looking for water. And meat. DOOM! or we could have another 50,000,000 years to prepare. |

Quote HistoryQuoted: Don't tease the 'tards 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. |
