only phase relationships can move lightspeed in normal EM systemsWell, I guess I’m just asking if you have a rotating magnetic field generator, like an AC motor, and plug in a high enough frequency, does the EM field ever reach a rotating velocity surpassing that of light?
mass can move lightspeed and faster
gravity and inertia aren't magic.
there's a reason
lightspeed time dilation only happens cuz you're dragging the entire universe.
requires all the energy in the universe
