We're all going to die

I don't usually follow astronomical news, but someone else showed me this and I thought it was only fair that you should know, too :juggle2:

An interesting, if a bit scary, speculative sidelight is that if a Type Ia supernova explosion occurs within 1,000 parsecs (1 parsec = 3.26 light-years) of Earth, then the gamma radiation emitted by the supernova would fry the Earth, dumping as much gamma radiation (~100,000 ergs/square centimeter) into our planet, which is equivalent to the gamma ray input of 1,000 solar flares simultaneously.

The production of nitrous oxides in Earth's atmosphere by the supernova's gamma rays would completely destroy the ozone layer if the supernova went off within 1,000 parsecs.

Any last words can be submitted in this thread.

Awesome, one more thing to be afraid of.

Gamma bursts? Been there, done that apocalyptic scenario. If this was common enough to be a real danger, it would have happened already.

There's only 1 star, Spica, within that envelope that could go nova, and thats 260 ly away (~847 pc) and isn't big enough to cause an extinction level event at that distance (it would have to be less than 25 ly)

Gamma Ray bursts are much rarer than supernovae, but can be fatal up to 7,000 ly, again howeverwe would have to be "right in the beam" to be affected, Phil Plait the astronomer has calculated that the odds of this happening in your lifetime are about 14,000,000,000 to 1.

Don't worry about it. :2thumbsup:

It's called a gamma ray burst, and no, this star isn't massive enough for that.

After seeing the documentary Highlander II : The Quickening, I feel pretty confident that we'll survive the destruction of our ozon layer.

Old news....

Life is fatal STD.

Infact we might not all die, I'm hoping scientists find a way to make us immortal.

don't know about you saps, but i'm getting my head frozen, for the win.

:balloon2: Reassuring.

I've already told my children, the reason why they can't have a new little brother or sister, is because I'm saving my money so that I can replace roughly 95% of my body with new age cybernetics, and titanium alloy. Gamma Ray Burst you say? a frivolous danger to be sure.

Heh - I guess you don't realise that a GRB would cause a massive EMP likely frying all unshielded circuits?

EPIC BURN!!! :laugh4::laugh4::laugh4:

EDIT: I did not realise that was a pun. What I meant to say was, you know, when someone wins an argument so categorically, a situation which qualifies the use of the phrase "epic burn" on the loser, suggesting they just got beat with an epic win...
