Cosmic Microwave Background Radiation Preferred Directions and Asymmetry in Lorentz Violation

We present the statistical analysis testing the coincidence of anisotropies in Cosmic Microwave Background Radiation (CMBR) with those one coming from Local Lorentz Invariance electromagnetic tests (LLI Coil experiment). The resulting agreement between some CMBR's anisotropies directions and the LLI coil experiment measurements of LLI coil violation seems to suggest the existence of a possible fundamental asymmetry related to the presence of an underlying anisotropy common to these two different phenomena.
