There are some "Giant" planets turning into white dawrfs outside of our galaxy when they pop it gonna go with a billion billion worth of force of TNT and our little cluster of planets is only 3000 light years away from it.

Reckon it will strip the atmosphere.

I read it at thesun.co.uk a national paper but cant get it back up - anyone got anything on this? :huh:

They say we will see it in the sky - end of the world rocks - no one is safe!

I want teh earth to blow up but no before we get rid of that pesky moon.

Planets can't turn into white dwarfs... stars do.

Depends on size and mass of the star too. Can change into white or brown dwarfs, or a black hole.

Actually, I thought the Andromeda galaxy is supposed to collide with ours in a few billion years. Not sure if it's going to be the end of the world, but it should be one hell of a fireworks show.

I think it'll be more than a few billion years. We'll be long gone by then and most of what we know on earth. Considering the center of the milky way galaxy is a super-massive black hole, I think it'll annihilate Andromeda after what's in our own galaxy.

^ Yeah but thats billions on billions.

They dont even know when - a solar flair is more probable. But dont think its been documented.

 

I think it was Venus that had a "storm" and it was about 50 times bigger than earth in one swirling mass on its surface.

Fucking awesome.

If I'm not mistaken, isn't our Sun supposed to burn out before then and take most of our solar system with it?

Thats if our sun turns into a black hole, which i'm not sure on whether it will or wont. But even before than earth will gravitate closer towards the sun in orbit while Mercery gets obliterated by the sun, we'll be the second planet from it and will become like Venus is before it takes Mercury's place. But that'll happen sooner than the Milky Way colliding with Andromeda.

none of that is gonna matter when a huge asteroid lands in your back yard. there is an asteroid that is going to pass within the orbit of the moon in like 2023, some are sayig it will pass close enough to smash into our GPS satellites. at that time it may pass within a small window of space where our gravity could sling shot it back right into us on it's second pass in like 2036.

Yeah you're talking about Apophis. Probably the most dangerous NEO in modern times, but I think we have the technology to deal with it before it potentially changes course for Earth (if it does).

 

I'd also worry about Yellowstone erupting. That's probably the most imminent and large-scale threat (short of an asteroid hitting us) that may happen and while it won't kill all humans it'll cover half the planet in an ash covered winter for many years, bottle-necking human lineage a second time as it did during the Toba Catastrophe.
