One of the pitfalls with relative velocity is it can create energy illusions that become misinterpreted.
For example, one of the original tests that verified special relativity were particle accelerator experiments using radioactive atoms that had half-lives. If there was time dilation, due to motion, the half life should get longer, which was observed.
If we apply relative motion, from the POV of the moving radioactive atoms, the lab will appear to have the relative motion. If we had another batch of radio active material, on a lab bench, it should appear to show a longer half life, relative to the moving reference. After the experiment was done only the moving reference had any real change. The moving reference saw kinetic energy that was not there, fooling itself into add imaginary affects, that could not be proven; when compared.
My conclusion is special relativity works, in reality, only for a reference that has tangible energy driving it. Special relativity, to create real affects needs kinetic energy input. Only the moving radioactive atoms, driven by the energy within magnetics fields, will exhibit a real affect. The final affect; concentration, was reference dependent, since only one reference showed any tangible affect.
The same affect occurs in space clocks in motion. All the clocks on the earth will not change, just because these appears to be in motion relative to a satellite. When we bring the clock back to earth to compare, the satellite clock was hallucinating. That fantasy, if it fools you, can lead to theories that are not real, but can appear to be justified, based on what you appear to see.
