Title: Cosmological dipoles

Abstract: It is well known that the cosmic microwave background contains a strong dipole pattern on the sky, usually considered to be the result of our motion of several hundred kilometres per second with respect to the “CMB rest frame”.  But there has been a long debate in the literature about whether a fraction of this dipole could be “intrinsic”, with one side of the sky being genuinely hotter than the other side, and no velocity-boosting involved.  In addition to the CMB dipole, there are other effects that would be caused by boosting, including some claims that the standard cosmological picture is already in trouble.
