I love Star trek and I was thinking, how to create a warp drive. I have read a discusion about EM waves on this forum, there was written that they do not need any medium for propagation and : “In a simplified sense the oscillating E field sustains the oscillating B field which sustains the oscillating E field ...“ Does it mean, that they do not affect space-time? Can space-time be affected or warped by quantum of energy (without weight), for example by photons? I taught that if we put a one way current pulses with enough energy and frequency to ship`s hull, the formed EM field could work as paddle in space-time. Couldn`t it? What would happen if the change of magnetic field, caused by current pulses, is faster than light? For example, if magnetic induction is 1Tesla 10meters from the hull, the wave length (or “impuse length“:) is 1meter, asuming that speed of current is close to speed of light, the magnetic field (the point with the induction 1T) would “travel“ 20meters, while the current (or light) 1meter.
