Light traveling at light speed

[Gear300]

Since I've only heard of light traveling at light speed, then I'd assume that the force carriers that are not photons probably do have mass. I was wondering how these other field interactions propagate...do they displace themselves at a certain speed?

which fields are you talking about , gravity for example propagates at the speed of light , and the strong nuclear force is mediated by gluons or pi mesons i can't remember.

How do each of the force carriers propagate (I'm not too knowledgeable of the subject)? Since photons are the force carriers for the EM force, how are they propagating in a static (non-accelerating) electric field? How do the strong and weak nuclear forces propagate?
