How long do you think the world will last

longer than I will.

Current data indicates at least 3 billion years.

Current observations indicate that the Andromeda galaxy will collide with ours in about 3 billion years.

That could set the stage for Earth's destruction.

According to http://www.newscientist.com/article/dn13369 , it will have the greatest probability of ending in 7.6 billion years from now.

"In a few billion years, the Sun will fuse the last of its hydrogen into helium, turn into a red giant and expand to 250 times its current size. At first, the Sun's loss of mass will loosen its gravitational pull on Earth, which will allow the planet to migrate to a wider orbit about 7.6 billion years from now.

This process has led some to speculate that the Earth might escape destruction - but survival now seems impossible, says Peter Schröder of the University of Guanajuato in Mexico and Robert Smith of the University of Sussex in the UK.

They created the most detailed model to date of the Sun's transition to a red giant, based on observations of six nearby red giant stars. Sure enough, they found that Earth's orbit will widen at first. But Earth will also induce a 'tidal bulge' on the Sun's surface, with its own gravitational pull. The bulge will lag just behind the Earth in its orbit, slowing it down enough to drag it to a fiery demise."

science is a lie and can't determine when
the answer is when GOD WANT'S TO
read the bible it will give you clues to when the end is close

I don't know. Maybe it will last for a long time and maybe for a short time. The world will be last for a long time, but if some asteroids or enormous rocks hits the Earth than we will be on a big trouble.

It will last at least until I die.

Beyond that, I'm not making any predictions =)

For a long long time.

The world will last basically forever. Humanity, not nearly so long.

The earth will be around forever. The "world" of mankind alienated from God, can't give you a time frame on that.

Because of my work in cryptography communication during the "Cuban Crisis", the published military manual stated that I would have but 90 seconds to live once war broke out.

Do you actually think I really care when the world will end?

Well beyond you and I and the whole human race, and it's waiting to thank God for the relief of that :)

About another five billion years, when the Sun expands into a red giant. Barring anything else prior.
