Can asymmetrical Lorentz forces account for Relativistic affects near the speed of light? The underlying thought here is that at low relativistic speeds all objects are subjected to emf radiation from all directions.  
This is basically the sum of all the radiation (light, infra-red, x-rays, gamma rays etc)  hitting us from all sides from distant stars/quasars etc.  According to Lorentz these passing fields must exert some force effects on the atomic particles (excepting maybe neutrons).  The results of these forces are, in steady state, balanced from all sides (much like we don't feel the massive pressure of air at 14psi pressing upon us since it's balanced on all sides).
However, as an object's speed increases in any direction, then there must be a change in this balance.  The object's leading edge would be experiencing more directed emf at higher frequencies while the trailing end is experiencing them at lower frequencies (lower energies). This is similar to the Doppler effect or red shift.  
The question then becomes, can it be proven, or dis-proven (or has someone already tried to) that this doppler-like effect or compression of emf energy contributes to the relativistic changes to that same mass as it approaches C? 
One piece of astronomical evidence for this would be the observation that galaxies at the universe's far edge appear to be leaving us at > C.  Could it be that those galaxies are no longer running into to emf repulsion from their leading edge (farthest from us) and thus the speed of light is no longer imposed upon them by emf?
Any references to research on this topic are appreciated.
 A: The only naturally occurring symmetry breaking radiation of this kind is the CMB. Unless you are talking about charged particles of more than approx. 1e19eV energy (in the CMB rest system), the effects are negligible, as far as I know. For those ultrahigh energy particles, however, this so called Greisen–Zatsepin–Kuzmin limit (GZK limit) forms a cosmic fog that does slow them down, so that the highest energy cosmic rays have to be produced in our cosmic neighborhood (probably within the local supercluster), or they would not reach us. Below that energy limit (charged particle) cosmic rays are mostly effected by galactic magnetic fields. 
In addition there is at least one rather old paper about the exposure of interstellar rockets traveling at up to 90% of the speed of light to dust and interstellar gas. The abrasion and heating due to collisions does increase quite a bit as a macroscopic body approaches the speed of light, so this may set a practical limit to travel near the speed of light. The effect of light, x-ray, gamma ray and cosmic ray sources are basically negligible compared to the dust and gas, because those particles are already traveling either at or close to the speed of light, so adding a slightly relativistic boost to that will only increase their energy by a trivial amount. Hitting gas and, much worse, dust particles, on the other hand, poses a non-trivial challenge to the hull integrity of relativistic projectiles.
