Mr. Francis invited comments,

Yes, and many thanks. 

Quoting C. Francis,

"Teleparallel displacement requires a preferred coordinate system.
This
will be determined from the requirements of wave mechanics and
exhibited
in the instance of a homogeneous isotropic cosmos. Torsion will be
removed as part of wave function collapse and in the classical
correspondence gravity is described by curvature, as is normal in
general relativity. It will be shown that this prescription reduces to
the affine connection and that geodesic motion is preserved for
classical particles and of a beam of light."

Using the following in the same paragraph,

"preferred coordinate system", " wave mechanics",
"isotropic cosmos", "wave function collapse",
"normal in general relativity",  "geodesic motion".

is really hard to understand.

Yes. I have rewritten the first couple of paras, leaving out some stuff which is dealt with later, although I think whatever I do the paper is not going to be easy to understand. It now begins:


There are well known and substantial difficulties in formulating quantum theories in curved spacetime (Dirac, 1964; Fulling, 1989; Wald, 1994). Einstein (1930) found problems with electrodynamics in curved space time, and suggested that the affine connection of general relativity might be replaced with a teleparallel connection. Such a replacement can be motivated in the orthodox interpretation of quantum mechanics in which it does not make sense to talk of position between measurements and hence it does not make sense to talk of transport along a path. It does make sense to establish a connection empirically, using light arriving at the detector to determine coordinates at the source. This will be called a teleconnection.

This is not a theory of teleparallel gravity in the usual sense (see e.g. Arcos and Pereira, 2004). Torsion will be removed as part of wave function collapse and in the classical correspondence gravity is described by curvature, as is normal in general relativity. It will be seen that this prescription reduces to the affine connection in the classical correspondence and that geodesic motion is preserved for classical particles and for a beam of light. The current paper seeks to show the empirical predictions of quantum theory using teleparallel displacement

I'm unable to determine if the "preferred CS"
contradicts GR, because of the ambiguous conditions.

There is a conflict with gr, because I am getting some different results. But in fact the preferred CS is only used for quantum motions, not classical ones. The only place this affects gr is that light from a an astronomical object is treated as a quantum motion, with the net result that cosmological red shift appears differently in the model.

As it comes out, the preferred coordinate system is conformally flat coords, stretched (for mysterious reasons explained in the paper) by a factor 2 in the (t,r) plane, and a factor 1/2 in the angular directions. (I think this is related to spin 1/2, but haven't shown it yet). The stretching is given for good reasons, and gets empirical support from the relationship between the MOND and Pioneer anomalies. But for reasons which I don't understand, whenever I try to post the paper only part of it arrives with the moderator, so all this is missing from what has been posted so far.
