The Cosmic Microwave Background rest frame provides a physically distinguished reference frame where the CMB appears isotropic, a concept well-supported in astrophysical literature regarding cosmic kinematics.

The analysis

Papers [3] and [4] explicitly discuss the CMB rest frame as a preferred physical frame defined by the isotropy of the radiation and kinematic measurements.
