It is believed that gravity, the weakest of the four forces propagates at the speed of light, cf. e.g. this Phys.SE post. One would expect (perhaps erroneously) that the other, stronger, forces acted at an even quicker speed. Of course, it is not like that. At least, it's not for electromagnetism. What do we know about the speed of the other two?
