## What happens to time when gravity is absent

If it has been determined that time/space is always relative to gravity as observed in several equations (correct me if i'm wrong), then does time cease to exist if viewed from a relative plane perspective that lacks any form of gravity? Could a relative plane perspective even exist without being relative to a mass that observes gravity?

edit: and say you can never have rule out gravity, can a comparable state be formed by having to gravitational fields directly and perfectly counter act each other creating some sort of equilibrium?

 Special Relativity is space/time without gravity(curvature).
 so i guess my question would be what is time in relation to special relativity edit: According to newton when you enter into the exact center of earth you observe an equal gravitation pull on all sides, so does time stop there?

The force of gravity at the centre of the Earth (or anywhere inside the hollow of a sphere with a solid shell) is zero. Gravitational time dilation is determined by gravitational potential, sqrt(GM/R) and the potential does not go to zero at the centre of the Earth. As an object goes towards the centre of the Earth its gravitational potential is always increasing, reaching a maximum at the centre of the Earth.

As kev points out, the gravitational potential increases. GR predicts that the clock rate will decrease with respect to the surface. The clocks will not stop, their rate will decrease by a very small amount. See also here: http://en.wikipedia.org/wiki/Pound-R...ton_experiment

I think you're wrong, I've never heard general relativity described in this way.

It is true that, in general relativity, if two clocks are at rest relative to one another but one is in a stronger gravitational field, it will tick more slowly than the one in the weaker gravitational field. I presume that was what was meant.
