Electromagnetic waves convey action from a sources to sinks much like Newton's cradle.
Maxwell modeled the transfer very well with his "displacement current".
In order to explain how electromagnetic action propagated, Maxwell came up with the concept of "dielectric displacement" ===================================================== Yes, we know, aether. Seven years after Maxwell's death Michelson made it redundant, rendering Maxwell's theory of permittivity of aether obsolete. When the substance vanishes its properties vanish too. Your Newton's cradle analogy is a good one; but for a magnetic field, not a displacement current. Had Maxwell lived he'd have modified his theory. When the first ball is raised it has potential energy and no motion, akin to a voltage. When released the PE falls to zero and the KE is at a maximum, akin to a magnetic field. Striking the next ball, the first ball stops dead and the KE is transferred to the next ball which rises. You've got displacement KE, but not displacement current. You can do the same with a chain of transformers, the secondary winding connected to the primary of the next transformer, but the links in the chain are alternating copper loop, iron loop, copper loop, iron loop... with an electric current in the copper and a magnetic flux in the iron. So I'll say again: What medium is that, Potty? Ectoplasm, the ghost of aether? Electromagnetic waves are the alternating fields that exist without the hardware of copper and iron. AND WITHOUT AETHER. Corollary: The velocity of light is source dependent, not aether dependent or observer dependent. Newton's cradle (if you want the analogy) works just the same in the ISS travelling at 17,000 mph and so does MMX. Newton would agree, Galileo would agree, William of Ockham would agree. Throw that gamma shit out, it's for the birds.
