How fast are the forces of a collision?

I think frame dragging, with gravity, shows that at least gravity is not instantaneous, because if it is instantaneous, then how would it produce drag - it would affect everything around the gravitating body in no time? Unless it's not instantaneous, and maybe gravitons and/or spacetime warping have momentum and are on a non-straight trajectory from a rotating, gravitating body. That's interesting: Spacetime exhibiting momentum!

I've heard entanglement is either faster than light, or instantaneous.

In quantum mechanics, there are force carrier particles. So, since they travel so fast, is there time dilation or length contraction for those force carriers? Like for gravitons. As they travel through space to influence a body, is there time dilation or length contraction for the force carrier particles? How would we find out? If we can, then that would be a good step in uniting the two schools of thought!

Thanks,
