What will be the Life of earth?In other words How long earth will survive in this universe?

well somewhere down the road (4.5 - 5 billion years from now) the sun will start to turn into a red giant and start to get bigger. Theory is that one of 2 things will happen - Earth will get sucked up and end up like Mercury or if the sun expands fast enough it could push the Earth to a different orbit - then we will either be fine or crash into Mars/Jupiter or just keep on going (rouge planet) Now assume that we land somewhere between Mars and Jupiter and that everything is OK - the sun at that size could spark the moons of Jupiter and Saturn to become hospitable to us (yay new property). That though will (sadly) last only another 3-4 billion years when the Sun will then shrink to a white dwarf - thus everything left will surely die out.

in about a billion years the sun will start to exhaust its fuel and start to expand because of weakened gravity. The earth will be burned to a cinder along with Mercury and Venus.

It's also been report that there is a meteor scheduled to hit the earth in about 700 years but its unknow if the impact will be great enough to wipe out all life.

Earth itself will last as long as the sun holds up. Which is aprox. 5 bil. years. The sun has used up roughly half of its water (H) supplies. Even if a meteor strikes earth will most likely continue to exist even if life itself on this planet does not.

The earth will survive untill our Sun goes supernova, or something crashes into us by coming out of orbit. but i doubt we would be alive to see that day.

Hello,,depends on the scientists that refuse to stop killing it. I say a couple more years,,maybe those Mayans knew something about the brain power of idiots being paid by the political agenda,,who really cares ,,every thing is gonna die sometime,,I just hope it's a nice visual effect!!

Makes me imagine of the 5 ancestors. it variety of feels somewhat too cliche and heavy fantasy. possibly there have been six those who were treated as immortal spirits, and the dragon replaced right into a human with dragon markings who needed to set fireplace to cities internationally? heavily regardless of the indisputable fact that, develop your grammar.

untill the sun blows up and kills humanity... but that wont happen because before that we will teleport to heaven and all the bad people will be left on earth and start wars and kill themselfs

Until our sun goes red giant, projected to be about 4.5 to 5.0 billion years from now.
