WebDec 13, 2024 · The existence of a CMB frame asserts that there exists a global frame in which the universe is (approximately) space-translationally and rotationally invariant (though not time-translationally- or boost-invariant) - a completely logically independent statement. What frame of reference in the universe is (most) rotation-neutral? WebAnswer (1 of 8): Why can't the CMB be a universal reference frame?
