Again, it's an observed phenomenon, and to be able to observe it at all, you have to be in a separate reference frame.
The causal factor is (ultimately) the upper limit on light speed.
Sound is absolutely a wave. On the other hand, EM is both a wave AND an particle and hence it is neither, really.
IIRC, inertia ("resistance to acceleration") is explained by the Higgs field. Not that that's much of an explanation to us laymen.
