電磁波
Moreover, the science fiction concepts for beaming do not get it exactly clear what kind of radiation the matter would be converted to. There are only two types of radiation in physics that come into question: Electromagnetic radiation (radio waves, light, X-rays, gamma rays etc.) and particle radiation (alpha and beta rays, neutrons, neutrinos, atoms etc.). According to the current state of knowledge, electromagnetic radiation alone cannot transport matter, since it only transmits the energy, but not the baryons and leptons required to create atoms. If, alternatively, a beam of matter particles was sent, this would offer hardly any advantage over transporting the object as a whole. On the one hand, accelerating and decelerating the particles would require the same amount of energy as for the original object. So there would be no speed advantage. On the other hand, particle beams can hardly penetrate layers of matter along the transmission path (which is supposedly possible in the science-fiction concepts within some limits).
