If you calculated it using the equations for radiation from charge by substituting mass for q you wind up with

...a mess, because the units would be hopelessly buggered, and because EM waves propagate as dipole fluctuations while gravitational waves propagate as quadrupole fluctuations, and because electromagnetism is a vector interaction while gravity is a tensor interaction, and so on.

negative energy flow, that is the "gravitational Poynting vector" for the gravitational and cogravitational field is directed inward.

Now you're confusing the field vector with the flow of energy.

You culled all this from the work of someone named Roland Dishington, you say? I'm afraid that all I've learned about him is that he served on the USC fencing team in the dismal 1941 season.

No this isn't from Roland Dishington. I just asked if you heard of him.

So is charge fixed to a moving dielectric considered a current? Is the electric field of this moving charge (that is, current) in the direction of the current density vector? Or is there no electric field of the charge in motion because it is mechanically forced to move?

I'm trying to do the Lorentz contraction calculation for the MM experiment. My problem is in determining the velocity of the apparatus. Is it just the tangential velocity at the earth's surface due to rotation or do I have to add the velocity of the earth going around the sun or also include the velocities of the solar system as well? What reference frame is used for the Lorentz contraction calculation? I'm confused because there is no relative motion between the observer and apparatus. Could you help me with this?
