Relativity Principle Revisited

The premise of relativity, as I understand it, is based upon an abstraction called the Galilean/Newtonian Relativity Principle.


Simply stated, it requires that the laws of physics exist independently of inertia; that any experiment performed in one inertial frame of reference will yield precisely the same results as if performed in any other inertial frame. In other words, the laws of physics apply equally to all inertial frames of reference and that no inertial frame is "preferred"... (please correct me if I'm wrong here)


The thing is... If you take the modern knowledge of the Universe as it seems to be, it is clear that there is no such thing as an "inertial frame". All through the universe the cosmic background radiation (photons, gravitons, and neutrinos) works to populate space with a dense medium that creates drag in all free dimensions-everywhere you go.


First of all, any spaceship traveling through space anywhere in the Universe could (if properly equipped) measure its absolute velocity relative the cosmic background simply by detecting the Doppler shift in radiation (fore and aft, port and starboard, up and down) So it is obvious on the face of things that EACH inertial frame of reference is clearly distinguishable from EVERY other frame- in utter defiance of the Relativity Principle.


Furthermore, it is also clear that "inertial frames" are simply impossible fictions ANYWHERE in the Universe. The background radiation that permeates the universe will create drag that simply forbids inertia.

Thus, the concept of "inertia" is not a plausible "abstraction". It is instead a plain fiction.


Why should we accept a theory based on the Relativity Principle?
