How do you think the world will end?

[The Don]

when the sun turns into a red giant

Actually, if that does happen, all of life on earth would have been destroyed before it reaches that fase as the build up of heat and brightness would destroy majority of the hydrogen on the earth.

we were close to wiping the human race out in one of the wars when people started getting nuclear weapons and didn't use them, since we are here today. I think mankind will kill it's self in one way or another, but when the actual planet itself dies will be the build up to the red giant phase of the sun as we will either be engulfed by the enlarging sun or the sun will be so close that it melts that planet. I'm glad i listened in science now

It's pretty probable to happen before the Sun dies imo.

Either

a) humans make the planet uninhabitable essentially destroying it
b) an astronomical disaster such as an asteroid.

1. Killing ourselves by being Nazis
2. Asteroids
3. Mass disease or famine possibly brought on by overpopulation
4. Extreme climate change
5. Eventually a super nova

The world is going to evolve, we will keep damaging our planet with gases and polluting the air. In time this will increase the temperatures which will rise sea levels, crops will not survive and in time we will have nothing to survive on. So this professor guy said on the One Show lol

Won't happen. :frust:

Our suns not big enough to become a super nova so it will be a white dwarf i think the closest star to us that is most likely to become a super nova will be Betelgeuse which is apparently meant to happen in the next 5/10 years :S i can't remember apparently there was something about it on the news

Yep, any time within the next million or so years. Culd happen in 5 minutes time.

I don't think it will just evolve as it has done for millions of years.

This! Nailed it in one, +rep.

I think a lot of you need to watch bbc 1/bbc 4 shows by Dr Iain Stewart. He's an amazing guy, I've watched all his shows whenever they're on and he explained everything from evolution of earth to what we call global warming. It's been happening for millions upon millions of years. Dear god the ice age was global warming!?! People seem to constantly forget our time's the equivilant of like a day for the earth... we're nothing compared to this old bird we live on.

We'll die off, earth will evolve and who knows?

The earth will evolve? How will it evolve when it get's eaten by the sun ????????????

Anyway when the world ends... probably something like an asteroid or we literally tear the planet apart
