Am I right in assuming that Gravity Probe B has proved that the rotation of the Earth (@~465metres /sec.) 'swirls' space-time in the same sort of way that a rotating ball will swirl a fluid?
I ask because if this is the case, then the forward motion of the Earth (@~360km/sec.) must also produce a linear dragging which is detectable, much like a speedboat leaves a wake in it's path.
Also, if the rotating mass of the Earth causes frame dragging then common sense insists that matter must also 'displace' space time in a manner similar to Archimedes principle.
