"unlike the "time delay" canard, the gravitomagnetic effect depends on the speed of the observer" frame of reference.

Now what do we say about a phenomenon that is not consistently explained in *every* frame of reference, not just one?!

Now what do we say about a phenomenon that is not consistently explained in *every* frame of reference, not just one?!

The phenomenon in question is the motions of physical bodies, and those motions will be agreed upon for all observers. The gravitomagnetic effect guarantees that, even in the face of different spacetime perspectives.
