CosmoCoffee

This is an alternative gravitational theory that has incorporated the conservation of gravitational energy (Zhao's "mass variance") in SR, Self Creation Cosmology has done so in GR (see gr-qc/0302026 "Resolving the Degeneracy: Experimental tests of the New Self Creation Cosmology and a heterodox prediction for Gravity Probe B").

Both theories may be falsified - along with GR - in the geodetic and frame-dragging measurements of the Gravity Probe B experiment, which at present is in the data analysis stage.
We wait and see!

Now that GP-B's preliminary results are in, do we know enough for a verdict? Or must we wait another 8 months or so for the frame-dragging result?

Both SCC and Zhao's "mass variance" theory are falsified by the GP-B geodetic result.

We wait for the frame-dragging result, to see if that falsifies GR!
