The first is the prejudice that an absolute reference frame allegedly is impossible according to Einstein's theory.
In particular, Zelmanov showed  that an absolute reference frame is allowed in a finite closed universe, if such a reference frame is linked to the global rotation or the global deformation of the universe.
Later, Zelmanov's followers also voiced, in their scientific presentations, the possibility of an absolute reference frame in a finite closed universe.
It should be noted that an absolute reference frame is impossible in the space-time of Special Relativity.
While Postman and Lauer presented their data without taking sides, Mathewson has adopted the heretical view that the cosmic background radiation does not provide an absolute reference frame
with which to measure velocities.
As a consequence, we will arrive at transformation laws similar to Einstein's which depend on the absolute reference frame but change asymptotically to Einstein form in certain important application cases.
The prerequisite is that a global, absolute reference frame does not exist.
If hotspots were fixed to the interior of the earth, they would offer a system of absolute reference points--in effect, an absolute reference frame
It was shown already in the 1940's, by Abraham Zelmanov, a prominent scientist in the theory of relativity and cosmology, that the space-time of General Relativity permits absolute reference frames
connected to the anisotropy of the fields of the space rotation or deformation of the whole Universe, i.
