The World will end, and I doubt you or anyone you know will be alive to see or hear about it... Not worth worrying about, and a little bit of a boring conspiracy

Considering all the Galaxies out there and how perfect one must be to create a living environment I bet before a collision we will be in contact with another Galaxy or life form. I think a nuclear warfare is highly unlikely because one single leader killing all the people on earth is just to hard.

I bet it will be in millions of years by a huge collision.

Dinosaurs will come back!

That question is floating around in my head all the time, I simply do not know

Gossip wrote Dinosaurs will come back!

Agreed we will all be killed by dinosaurs.

Jeeves wrote I don't think that nuclear war is likely, humanoid species' have survived super volcanoes before, mega tsunami's are rare, and most of the world are unaffected by them individually, the Earth's crust moves so slowly that massive geological change is unlikely.

For the destruction of humanity itself I see only 3 real threats.
- Overpopulation, leading to riots, famine, and lack of enough resources to feed ourselves.
- A meteor, granted it will have to be bigger than the one which wiped out the dinosaurs, maybe even an interplanetary collision would be needed.
- A disease pandemic, something strong enough, and resistant enough that it would wipe us all out before we could synthesize a cure.

When it comes to the end of the world itself, I think that it's going to be either an interplanetary collision or in 5 billion years when the sun 'dies.'
Even if the Earth survives being roasted by the expansion of the sun, once the sun has lost a lot of it's gravitational pull, Earth will be flung out of the solar system, and will probably end up hitting something sooner or later, resulting in it's destruction.

i agree with this. i think that we will overpopulate the earth (wich is already happening) and also that we will deplete our resources but even if any of this happens we are already trying to colonize mars so even if earth gets destroyed we will have the technology to survive on other planets and find new ways to live in other conditions

technically the world will end in over a trillion years when the sun is near dying. when the sun is near dying it will become very very very very very hot and everything on the surface will burn

From my perspective is that were all going to die from biological diseases or Government vs Society because if you think about it, Cancer could of beenmade by the government to slow down population rate, and one day theres going to be to many of us and im sure the government fears that we will someday take over and Dis-Obey Because they wont be able to kill us all. Hope that made sense

i think it will be a clash of the titans only joking i think Jesus will had a fight with the devil

Either a nuclear war or a meteorite.
