2012: Fear No Supernova

ScienceDaily (Dec. 28, 2011) — Given the incredible amounts of energy in a supernova explosion -- as much as the sun creates during its entire lifetime -- another erroneous doomsday theory is that such an explosion could happen in 2012 and harm life on Earth. However, given the vastness of space and the long times between supernovae, astronomers can say with certainty that there is no threatening star close enough to hurt Earth.


I've heard this theory pin-balled around ATS a number of times over the last few years. Personally I don't buy into ANY of the 2012 doomsday theories, but this one is something that many people seem to believe.

There are no stars of sufficient mass and age to go supernova any time soon near the vicinity of Earth.

I have heard of this theory before and thought on it for some time. I remember hearing about remnants of a Supernova that happened some distance away but making it's way toward Earth causing some problems; but not so sure about that. Even then it seems like it would be something after 2012. Also isn't there supposed to be a star "close enough" (not our own of course) that could cause problems but isn't really "scheduled" to go super for some time?

It's the question of when that the two articles go off the rails. Betelgeuse may explode tomorrow night, or it may not go kerblooie until the year 100,000 A.D. We don't know. But given that huge range, the odds of it blowing up next year are pretty slim.

Is this what you were thinking of?

Betelguese might be as close as 320 light years. Over the last 20 years, different sources have measured distances for Betelguese between 320 and 640 light years due to its variable nature. Experts have said many times that any supernova within 500 light years could be a problem for Earth.

We of course will not know that it has exploded until we see the light. It could have exploded 320 years ago.

If there is really such a thing like a faster than light neutrino, we can have an early warning against a supernova explosion.

I say our sun is going to go supernova but the explosion does not start at the core of the sun it begins at the heliopause, the inner solar system quantum phase shifts.

Our Sun is not large enough to explode.

The sun will not go supernova




The Sun does not have enough mass to explode as a supernova. Instead, in about 5 billion years, it will enter a red giant phase. Its outer layers will expand as the hydrogen fuel at the core is consumed and the core will contract and heat up. Hydrogen fusion will continue along a shell surrounding a helium core, which will steadily expand as more helium is produced. Once the core temperature reaches around 100 million kelvins, helium fusion at the core will begin producing carbon, and the Sun will enter the asymptotic giant branch phase.[29] Following the red giant phase, intense thermal pulsations will cause the Sun to throw off its outer layers, forming a planetary nebula. The only object that will remain after the outer layers are ejected is the extremely hot stellar core, which will slowly cool and fade as a white dwarf over many billions of years. This stellar evolution scenario is typical of low- to medium-mass stars.[94][95]
