Is the observation of betelgeuze losing mass actually an observation off the star itself or basicly from the light that we get from it (I have no idea how they actually measure those things). So let's say this happened a bit more then 600 years ago, it's actually possible (altough we would have to be incredibly lucky) to see this in 2012 or later. Or is this an observation of the star itself, and even if this happens in 2012 it will still take 600+ years for that light to reach earth? | ||

Think critically about this one for a second; light is currently the fastest known measurable speed. Unless we have a magic way to learn about distant objects - faster than the speed of light, then there's no way we can measure properties of distant objects faster than we would be able to observe radiation coming from it. | ||

Not to derail the thread too much, but if too many people honestly believe something will happen then they may cause something to happen. Thankfully I believe that most people aren't that retarded. Edit: obviously people here can't cause a supernova there... should go without saying that when I say "cause something" I mean something a little more down to earth. | ||

But for some reason when I read that betelgeuze is 640 lightyears from earth I didn't realize it would be close to impossible to actually measure it from that star itself. (well I may sound stupid again, but I guess even if they had the technology a long time ago, the thing used to measure (can't think of the english name atm) that would probably still be on it's way to there | ||

If it were true, and it means that we won't have night, then that would cause serious problems for many species on the planet, wouldn't it? since it will only be for a couple of weeks, I personally doubt any species will go extinct, though there is that possibillity, but the most major problems I think will be cat-animals, bats, snakes and other nocturnal creatures, us humans and other non-nocturnal creatures will simply struggle a bit more with falling asleep (of course a major problem for some animals in and of itself). | ||

Oh I did read that, for some reason I thought you and MageSoren were talking about something else. Fortunately Betelgeuse is a lot smaller than the kind of stars you need for those hypernovae. It still would be pretty sweet to see a nearby supernova though. | ||

At least try to read some of the thread before posting :/ Quite simply, nothing of the sort will ever happen. | ||

And I'm pretty sure Voyager has not even left our solar system yet, so the point is pretty much moot regardless. | ||

Did you guys know 1988 film Beetlejuice name is inspired by BETELGEUSE. "The star's unusual name inspired the 1988 film Beetlejuice, and script writer Michael McDowell was impressed at how many people made the connection. He added they had received a suggestion the sequel be named Sanduleak-69 202 after the former star of SN 1987A." | ||

We can't even pinpoint the exact mass of BeteIgeuse at the moment let alone know what is going on inside the core of the star, i.e. the part that matters, other than that it has probably already ignited helium burning. | ||

When I think about that sort of stuff I always forget things like that. @ MassHysteria I added your post to the OP | ||
