how do you think the world will end?

The sun is currently halfway through its lifetime, and when the sun dies, so do the inner planets of the solar system. So the earth has about four and a half billion years, at most.

Assuming the earth is still around by then, it will get swallowed up by the swelling sun along with Mercury, Mars, and Venus.

that trailer is completely freaking awesome! I'm psyched. I wasn't gonna see the movie and now I think I will. I love John Cusack. I haven't seen a movie in a theater in ages...like about 7 years or something.

I recommend you do, it's a fantastic film

It will be either:

1. When Jesus comes again, or

2. In millions of years from now when the sun runs out of juice.

The human world will end when the rat-men rise up from their oppression and take back the planet.

They're out there. Oh yes. They're out there...

More like billions.

How funny would it be if Jesus were to show up a day late.

"I bring love and peace and...Oh very funny, dad! Making me come all the way down here for nuffin'."

Apocalypse humor <3

Thats hilarious!!

aw someone already said it.
I will go fo the four lolcats of the apocolypse. And the final battle between ceiling cat and basement cat.

$5 on ceiling cat

All of this has happened before...

The world will end when Taiwan proposes reuniting with China...

And more importantly, the seas start to sweep a few islands, which cause massive upheaval in the world in general!

The irony about the climate change furore being that regardless of the cause or extent of current climate change, sooner or later we as a species will have to cope with massive changes in climate, shoreline and ecology across the entire globe; over the timeline of (most) species the world is in constant flux. Our political institutions assume that the Earth is a static map carved up into permanent territorial nation states, but that isn't so for the medium and long term.

Agreed. Especially in the country I live in, why are we still existing? Should Singapore has a dual-citizenship scheme with Australia in case we get flooded? Lol

according to what i remember ...
the sun will only swallow mercury and venus when it expands.
earth's crust will be melted and the earth will continue to be a sphere, but it will be a sphere of molten material with a thick haze of oceanic atmosphere around it.
venus and mercury will be torn apart and destroyed.

but since there are large asteroids that collide with the earth with a frequency of only approx 60 million years (so far) , i think that the destruction of the earth (in terms of total extinction of life) is more likely to happen before the sun bellows it's final energy.

it is possible that a nearby supernova happened only 50 years ago. we would never be aware that it happened until we were annihilated by cosmic rays. (50 light years is dangerously close to a supernova),

it is possible that a planetoid has an extremely eccentric orbit and crosses our path once every ...say...6,500 years. it is possible that it's next orbit will intersect with ours.
no one would have ever documented it's last pass, and if it were headed directly toward us, it would only be seen as a spot that gets brighter, rather than a spot that moves.

the earth was hit by a small planetoid in the early stages of the solar system. the ejecta was so immense in volume and velocity, it achieved an orbit that it maintained and the debris coalesced to form the moon.
at first, the "moon" was only about 20,000 miles away, and for millions of years, the effect it had on the oceans tides was that it pulled the ocean up 10,000 ft, so the tides would have been cataclysmic then. (that was long before life started on earth).

over the ages, the moon has spiraled further and further away from the earth.
it will continue to do so until it breaks it's grip with earth, and then the mass of the "earth system" will be reduced.

a planetary collision with earth has happened in the early stages of the solar systems development, and now, most of the asteroids and planetoids have been sucked up by jupiter or saturn or the sun.
the asteroids in the belt between mars and jupiter are all quite stable in their orbits (the asteroid belt is possibly a planet that was destroyed by a collision earlier in the solar system's history as well).


anyway, here is my favorite video of how it may occur if a very large object collided with us.

i think it was rendered by a physics lab in japan.

even though it is grainy, it is extremely realistic to my mind. (except for the speed of the shadow crossing a city which is far too slow).
it seems correct in a "time frame" sense which is rare for representations of this nature.
