Another theory (WG) is here added to the list of predictions.
These theories and their predictions of the Gravity Probe B experiment have all been published in refereed journals, or on the Physics ArXiv. Most of them make specific and falsifiable alternative predictions of the outcomes.
A. GPB Geodetic precession (North-South)
B. GPB gravitomagnetic frame dragging precession (East-West)
We also have the tracking of the guide star IM Pegasi from the http://archive.ast.cam.ac.uk/hipp/hipparcos.html; just key in
'IM Pegassi' into the Target name of that Query Form. (Thank you Kris):RA (J1991.25) : 22h 53m 02.279"
DEC (J1991.25) : +160 50' 28.540"
Proper motion in RA : -0.02097 \pm 0.00063 arcsec/yr.
Proper motion in DEC : -0.02759 \pm 0.00043 arcsec/yr.
mag : 6.033 (HIPP)
MK spectral class : K1III SB (HIPP)
Of course, these alternative theories have to pass all the other tests of GR as detailed in Clifford Will's paper The Confrontation between General Relativity and Experiment.
Some of them might already have failed one or more of those tests.Garth
