Occured on Dec. 27th last year, 50,000 light years away. "Had this happened within 10 light-years of us, it would have severely damaged our atmosphere and possibly have triggered a mass extinction," said Bryan Gaensler of the Harvard-Smithsonian Center for Astrophysics (CfA).

So basically it was trillions of miles away.

How is this news? There's a big difference between 50,000 light years and 10 light years.

Yeah it it were closer it would have obliterated the earth. Do you think that would hurt?

How would this supposed mass extinction be a bad thing? Planet Earth has been cleansed many times in the past, why shouldn't it be cleansed again?

there's like nothing 10 light years away from us. The closet thing is 4.3 light years away.

AKA: never going to be an issue

The biggest star in the galaxy is only 8k light years away. Something like 100 times the sise of our sun. What do you think would happen if it went supernova, and one of the magnetic poles were pointed at earth? Earth go bye bye. Granted, it would be at least 8,000 years before it got here, but we would have about zero warning since the energy would be moving at nearly lightspeed.

Heck, Betelgeuse is like 425ly away. I wouldn't want to be around when it went supernova. It would be pretty, though.

Humans have only been around for a couple thousand, meh, we're nothing. Imagine what humans will have developed if they stick around for millions of years like some species *in awe of the thought, keep in mind computing as we know it is ONLY fifty some years old, picture computers THOUSANDS of years from now*

But that won't happen, the human race will kill itself LONG before anything out of our control does.

And... who's to say it didn't supernova 7999 years ago...

Also, I don't think there's a person on earth who understands a number like 10,000 trillion trillion trillion.. That's a BIG number!

Stephen Baxter's Manifold: Space is a good read, it takes this idea to its logical conclusion.

Manifold: Time is another good story ripped from the pages of the astronomy and physics journals, and is the first book in the trilogy (Space is second).

Eh... Humans have been around a lot longer than a couple thousand years...

Stars go supernova once in what, a trillion years? Multiply that by the number of stars eligible for that within 10 light years from Earth and you'll see what the odds are less than .0000000000000000000000001%
