Impeding and Unimpeding Gamma: The Principle of Impedance
  We demonstrate that gamma (from the Lorentz transformation of the Special Theory of Relativity) acts as an impediment to velocity changes only when it occurs inside motion energy transfer relationships. We also examine whether or not gamma unimpeded velocity changes violate either the constancy of light or elementary causality. We find that no violations occur. We conclude the paper with the procedure for a simple experiment, and further empirical evidence from the Hubble Space Telescope and W.M. Keck Observatory, all of which help to establish the veracity of our "principle of impedance."
