We know electric current travels around 200000 km/s.. Yet electrons are moving way much slower, just acting as a medium for the transportation of the energy. Can same principle apply for light? Although the energy flows at 300000 km/s the photons may actually not? Like, the energy traveling on a medium made of virtual photons, that in certain states comes to being and observed. Since photons are particle like, and wave like. Are there any studies answering how this is so? Thanks.
