Wait until you hear about the gluon, the mediator of the strong force, which is an excitation in the gluon field, and is also the only other particle that is massless and moves at C. However unlike the photon the excitation has a really short range because gluons interact with gluons and form flux tubes between quarks, the further you pull two quarks apart, the more energy you need to use, eventually the energy is so great that it spawns a new quark from the vacuum.

Compared to EM it's just weird as hell and tbh I don't like it.
