    Because it is a very complex subject to be answered with just a few phrases, I suggest that maybe you did read some articles, texts on the subject and if you have questions, share here. *Special Relativity (or Restricted): http://en.wikipedia.org/wiki/Special_relativity *General Relativity: http://en.wikipedia.org/wiki/General_relativity I know a little, maybe we can exchange some information. ;)

    if gravity is caused by warping of space time fabric........is there apparent force of gravity between two equal mass (since they warp space time fabric equally)?

    Well yes. Newton's Law of Universal Gravitation says: \[F_{g}=G\frac{M_{1}M_{2}}{r^2}\]where G is the gravitational constant:\[G = 6.7384 x 10^{11}N (m/kg)^2\]r is the distance between the objects M1/M2 are the masses of both objects

    Suroj, we actually don't know whether gravity is a force or a space-time curvature. Newton said that it was a force, but he was unaware of the cause of it. Einstein said that gravity is an acceleration due to curvature of space-time(he stated a cause of it). There's a lot of confusion on this. Some Modern Physicists attribute gravitation to a fundamental particle called graviton. The Nobel Prize on that is still unachieved! Read up on the topic Einstein and Gravitation.

    i think the theory says that when we consider two objects say A and B .. now let us suppose they are moving with certain velocities Va and Vb and in same direction. then velocity of B relative to A is Vb - Va ..... however if the 2nd object B were to be light then this could not happen.. in other words light doesnot travel with a ""relative velocity"". for nay object no matter what its own velocity is ... light's speed is always 3x10^8m/s
