My recollection is that the definition is about electromagnetic
radiation. I don't recall anything being mentioned about the other
forces (gravitational, weak, or strong).

The basic statement (from relativity) is that no information can
propogate faster than the speed of light. If Gravity propogated faster
than C, you could create a gravitational telegraph, and violate this
principle.

What you want is probably more related to general relativity than
to quantum mechanics.

I am not an expert in this area. I post these speculations only due to
the lack of other responses. Other opinions are more than welcome.
