If the speed of an elementary object not equal to the speed of light, then the elementary object is atom, which consists of many electromagnetic fields of photons, X-ray-photons and gamma-photons. The real "particles" of this world are the photon, X-ray-photon and gamma-photon particles. Other particles not exist.
Known that the several radioactive nucleuses emitt several energy gamma-photons. Speed of all gamma-photons is the speed of light. From this follows that the nucleuses consist of several mass gamma-photons.
Let's follow the logic. It is known that humans emit sweat, urine, and feces, which move at less than the speed of light. From this it follows that humans consist of sweat, urine, and feces.
Despite the claims of political partisans, I suspect this is not so.
