Could We Make Artificial Gravity?

True with present beliefs. One the speed of light is a propagation constant. not the speed of the wave-front. Check for a better definition of the wave-front using common sense. Place a vertical line in a two space. Allow a wavelet of length Lambda emitted to pass. How much time does it pass? Could be from zero to infinity seconds, i.e. red shift. Of course one may move into the front or the front can move into you, assuming plane waves, others may be defined. Gravity is a result of the field due to the many charges. Just consider superposition; if the charges centers are not at zero, equally then ... Gravity is an EM field over matter. We may create a field to oppose; however, a large and controllable energy source. Possible, TBD! Consider a stable set of charges within this field, may we create a field such that the stability of the body motion is insensitive to acceleration and is stabilize by a mock earth field, can we create an inverted feedback, to what seems to be a stable field?

Well.. I think it's true that we need mass to make gravity, but in order to create an artificial gravity we need to completely understand about gravity, including the material/power source to produce the right amount of energy that required to make gravity in a place/room
