In order to obtain a correct view of the action on the atomic particle level, one must begin at the beginning. One must start with raw materials that have proven referents and construct a theory that conforms to
observation and facts. The first step should be a study to determine the structure and nature of atomic particles. No such successful study currently exists by Quantum physicists. Science has developed its knowledge of nature through the scientific experiment. This is an empirical process. The Quantum people have taken the road of the exploration of the nature of atomic particles through the accelerator and mathematics, as they have no way to access the interior of atomic particles directly. When atomic particles are accelerated to near the speed of light, the mass of the particles vastly increases.
In the case of protons for instance, the particles have been increased in mass to over 25 times their rest mass by high energy accelerators and then smashed by launching them into rest matter. The pieces of the smashed proton are mainly relativistic mass, which if gathered up and weighed would confirm the fact.
