Betelgeuse gonna blow up (2012/doomsday exclusion zone)

[Titanium]

Wait, if astronomers are seeing it shrinking, hasn't it already blown up by now?

No.  Supergiant stars, or "Nova's," exhibit an unpredictable pattern of expansion and compression (shrinkage) throughout their lives.  It is only when the star exhausts its fuel and its core turns to solid iron that it begins to deteriorate and eventually cannot sustain its mass.  It explodes, shedding off layers of its crust and other inner spheres of gas, painting a nebula as the explosion radiates outward.  The core will remain, becoming a much cooler and smaller white dwarf burning off inefficient fuels for millions of years.

While it may very well have exploded already in real-time, according to our perspective it has not.  We will only see the explosion once the light from the event reaches our planet.

noo not beetle juice! :(

 Canis Majoris is he true Hyper Giant.

[Meekl]

Yeah lol I forgot about the fact that we're only seeing it 600 years ago since what we see is light.

loving time machine eyes, how do they work

[WhoDa?]

[Wedge]

This catastrophe will dwarf the Great Collapsing Hrung Disaster of Gal./Sid./Year 03758.

[Rughugger]

If it blows up just say it's name 3 times and it will magically reappear.

I bet I can start an entire new topic.

If 2012 wasnt real (Which it very true IS...), we would all die in 2055, anyway, because of North Korea appearently producing bombs... Atomic/nuclear bombs... They plan to carpet the entire Earth.

OH, and the Government will lie to you about everything (Random, yet true). RESIST! RESIST! RESIST!

 That's the problem.

But Luke, a parsec is a measure of distance, not time!

[Kalphiter]

Actually a Light Year is the distance light travels in one year AKA:
186,000 miles per second.
Oh wait... your saying the actual distance. Oops.

How long is a lightyear?

Also, the only supernova I'm aware that we have seen is 1989A.

If light travels 186,000 miles in one second, how many does it travel in a year?


Roughly calculated,
5865696000000 miles. x 600 = Whotheforgetknows.

Anyway, Betelguese is one huge motherforgeter, you could put a million of our star into it, maybe we will be able to see the blast in 600 years.

Aw maaaan, that's my favorite star

[Kalphiter]

5865696000000 miles. x 600

= (5865696 * 6) * 100000000

[Muffinmix]

What is the rate of its shrinkage?

Apparently its observable radius is decreasing by 300+ miles per hour. It's 85% as big as it was in the 1990s. There are also some "rumors" that it's no longer spherical.

Aw maaaan, that's my favorite star

And now you might get to see it go boom!

This will be visible during the daytime by the way
