Honestly? If that star exploded, it would be the end of all of us. The gamma ray burst would travel at the speed of light towards the planet, stripping the atmosphere, evaporate the oceans, burn everything less than 30 feet underground, and expose everything still alive to more than enough radiation to kill it.

Or maybe there's a god who's just completely insane and sends you to Detroit, Michigan in a new body if you ever utter the name "Pat Sajak".

the pic in the article makes the point that Betelgeuse is ****ing HUGE.
That was Venus compared to the sun. Here's a better picture.

Wow we got a wimpy sun. We should move to a planet around a better one.

For the record, that diagram is made of screenshots from this video.

Big stars do tend to go 'pop' much earlier then small ones, so doing that may just put us around a ticking thermonuclear bomb the size of the inner solar system...

Would you like to play a game?

How about global thermonuclear sun?

Okay, so, today this girl I know-Lauren, just took a sudden dis-interest in talking to me. Is she just on her period or something?

Actually Betelgeuse has already exploded. The light just hasn't reached us yet.

I should probably have my head checked, because I find myself in complete agreement with Nikov.

Not necessarily.  If the upper limit is 1000000 years from now.

It's around 640 light years away.  Which means the nova will happen 640 years before we see it.  It may have already exploded, but we don't know.

There comes a time when you must take off the soft, furry slippers of a boy and put on the shoes of a man.
Unless of course they don't fit properly and your feet blister up like bubble wrap.
Oh ho ho, but don't try to return the shoes, because they won't take them back once you've worn them.
Especially if that fat pig Tony is at the desk.

If I remember correctly, supernovas typically leave nebulae behind.  How do you think that would look from so close?

So my crundles are staying intact unless they're newly spawned... until they are exposed to anything that isn't at room temperature.  This mostly seems to mean blood, specifically, their own.  Then they go poof very quickly.

We could theoretically detect a missing star using gravity but we don't quite have enough precision in that field to detect it yet. And it would be a headache not only to get a machine to detect gravity in one direction, but then accurately pinpoint where the star is without being able to see where it is. What further complicates the matter is we don't even have an accurate measurement of the speed of gravity propagation either.

But it's theoretically possible!
