Gravity is the attractive force that a body exerts on another body. The amount of gravity exerted is proportional to the mass of the bodies. The more massive body "pulls" the lesser body to it...sorta. Actually the bodies pull toward each other. The Earth exerts gravity on you, and you exert gravity upon the Earth. But since the Earth is so much more massive than you are, the relative force you exert on the Earth is infintesimal, compared the the force the Earth exerts on you.
The only way the Earth will "run out of gravity" is if it ceases to have mass. Only 2 ways that can happen: either the Sun goes supernova and vaporizes the Earth, or the Earth in some way is obliterated into pieces so small that their exerted gravitational pull is negligible.

Your gravity is due to run out on September 23, 2010 unless you pay the sum of 240,713,843,001 ziggerions to the address below:
Universal Gravity and Silly Putty Corporation
1 Black Hole Avenue
Fifth Planet On The Left
Big Blue Star Next To The One With The Funny Name

Hi. Gravity gives us power by pulling down the water in a hydroelectric plant, or a waterwheel. But gravity has never shown any sign that it is somehow being reduced. It is probably the longest lasting force in the universe.

in your case the alternate fuel will most likely be methane gas, so when the gravitational pull lapses you will be able to propel yourself to another universe. Happy expulsion!

Gravity is a force of nature. It will not 'run out.'

We won't NEED alternate fuel! Since we will be able to fly without effort, we can just pack a load into our jet-packs and push off. Since friction will be negligible, we will be able to travel without fuel.

gravity is caused by the weight of earth i think, and therefore cannot go away.
