What makes Light move?

I understand that light moves at a velocity but what powers this movement. This seems like an unanswerable question to me but maybe you guys could shed some light on the matter. (terrible pun intended)

light can't *not* move. That's just its nature, and the nature of all massless things. They're always in motion. When it's created, it's created in motion and can't be stopped unless it's absorbed by/interacting with charged particles in a material.
