If you mean what will hold the world in its current orbit if lost its gravitation, the answer is simple: NOTHING.
If, hypothetically, the earth should lose its gravitation, this will most likely be caused if the earth stopped rotating around its own axis. This will cause the earth to not only lose its gravitation, but also probably cause the earth to stop revolving around the sun, thereby causing the destruction of earth, as it will either be pulled into the sun, or hit one of the other planets, or be ejected away from the sun, causing it to freeze over and become instantly lifeless.
One of the possible causes for such a calamity would be one or more space objects (asteroid, comet, etc.) of big enough size colliding with the earth. It could even reverse the direction in which the earth rotates.

The force of gravity requires an energy source in order for it to exist. The reason for this is that this force performs work, as in hydroelectric power, and to do this there must be an expenditure of energy. The energy source forming a gravitational field is the heat energy contained within the mass. The energy of a gravitational field is part of the physics trilogy: E = mc2, m = E/c2, and c2 = E/m. The last being that of a gravitational field, or a field of physical time. The only way in which a mass is able to lose gravitational potential is if all the heat energy within were to be lost.

Gravitation is a force between two masses. It is not a property of any specific object nor can it be lost.

So long as the Earth does not lose a significant portion of its mass (it actually gains millions of metric tonnes of mass each day), there will continue to be a gravitational attraction between it and other massive objects.

Nothing would be held on Earth if gravity stopped. The water in all rivers lakes and oceans would float away into space. Even the atmosphere would float away into space. Actually, the centrifugal force caused by the daily rotation of the Earth would probably cause the planet fly apart into space piece by piece. The planet would tear itself apart into asteroids and dust.

For the earth to not have any gravity means the earth does not exist. Gravity exist only because there is a celestial body in existance with enough mass to create gravity.(Earth) Gravity does not exist on its own.

If the earth suddenly lost all it"s gravity the earth would blow up in an incredible conflagration and bang.
