But at lower dimensions, the speed of the graviton must be superluminal.
That is a logical idea, is it accepted by the scientific community?

If gravitons go faster than light, tht would imply going back in time?

But that creates be many paradoxes. If gravitons go faster than light, then the gravity that is making then earth go at the same way all the years around the sun, is actually gravity from a lot time ago, or from a far future. But that would mean that then the force of momentum isn't equal to the force of gravity, but I think that it has been calculated to be equal. Or maybe there is also a particle that we haven't discovered and which is in charge of making objects have momentum/inertia in the universe?
