If we don't kill ourselves through nuclear war, I imagine a large asteroid will hit the Earth sometime before the Sun overheats the Earth. Unfortunately, it would seem the Earth is guaranteed to be destroyed by the sun even if we manage to avoid all other problems. But maybe by then we'll have started living on other planets, who knows. Mars One plans to send people to live on Mars in 2023, so it doesn't sound like it would be impossible.

Based on what our world looks like now, I think it would end by too much pollution. The air would be very polluted that you will be needing a breathing mask or gas mask to be able to breath outside. Then the bodies of water will be full of garbage at the point that you can't even see the water. And all the trees would run out of leaves and will die eventually. And all the animals will die either because of starvation or lack in oxygen intake. What will we do if ever this happened? Well, we can't do anything. We will just wait till we human also die. What we can do NOW is to clean the environment and help our government to keep out surroundings clean.

This may also happen: Electricity could run the whole world. I mean because of human creating so much powerful machines, there may be a chance that those mechanical beings would be the one who will take over the whole world.

But this is what I like to happen: Aliens! Extra terrestrial beings would land here at Earth and take over the world by a killing spree. They will kill all people with no warning! Their goal is to exterminate us all, and they will be the one who will live here. But that would be like impossible to happen.

Another thing that I would really like to happen is: Legendary and  Mystical beasts like giant flying dragons and dinosaurs would tear the world in half and eat all human beings and animals in sight. Also, this might sound very impossible to happen. But who knows?

Lastly: God will come down to Earth and the final judgement day will finally happen. He will wash out every sinful human in Earth! Quite wonderful isn't it?

How about you? What do you think will happen?

For me, I think the world can end from a surprise invasion from aliens and/or the earth heating up a lot from global warming to the point that we all burn to death. Maybe even the earth slowly coming closer to the sun to the point that the planet earth burns up. 

I had to quickly change the topic of my thread because I saw this thread only after I posted mine... derp

Anyway, my two bests bets are global nuclear annihilation, or the creation of some sort of super-virus that can't be contained, and I would give us at most 300-500 years.

If that doesn't happen, we are overdue for a global volcanism event(super volcano), which would pretty much have the same effect as nuclear annihilation.

Can't wait...

I think the world will freeze due to the sun going out, and then an asteroid will impale through earth, shattering it.

Well in about 5 billion years from now astronomers believe that the Sun , which is a star , will die and there for create a super nova . It will grow and grow engulfing the entire solar system . Yup . But if the Earth does die before that I'd say global warming

Well.. I think that in the end God will always decide when the world will end but many things could happen... I sometimes have a big imagination and thing about other worldly or fiction things like a zombie acaplse or something! That would be really creepy you know.. I guess we would just have to get through it even though I know that is not going to happen!

I go with many different theories of the ultimate fate of the universe, actually. Now, though, I'm going to list one. I think, in billions of years from now, our sun, like all stars, will die. Either going supernova or becoming a white dwarf, which leaves it as a nebula, will end our world. Going supernova would blast our planet, but becoming a white dwarf (that really is the term for it) would make it too cold to live. Also, it could become a Red Giant, meaning it would expand to ten times its own size, without exploding, however.

I think the world as we know it will end in the far future from a meteor collision, making Earth uninhabitable. Hopefully by then we will have evacuated earth and have made leaps in Terra-forming and sustained space survival. 

Beastmode64 : thank you for starting a thread like this i have some many things to tell. well for one a major thing that will maybe destroy the earth actually what am i kidding its HUMANS the bad ones will overrun us and kill us off and they will destroy earth as we know it. well thats my answer and i'm sure others can agree to that
