If I have a charge being conducted through a rotating superconductor, is there a rotational speed at which that charge is actually static?

Not according to Einstein's theory of relatively. Light- electromagnetism always moves at a constant speed. No object can "catch up" to a photon and hold it.

That's where things get weird. Our conceptions of 3 dimensional space are a reliable construct in a slow moving world. When velocities increase space and time change, e.g. time dilation and the Lorentz contraction.

At high speed we live in a sci fi universe.

Things get to be quite different in the realm of near absolute zero. Light can be stopped.

There isn't sufficient energy to get you up to 'sci fi' speed. See http://www.mazepath.com/uncleal/eotvos.htm and http://www.mazepath.com/uncleal/qz3.pdf for the truly awesome.

I believe that the question was if a charge circulation in a rotating superconductor could be made stationary if the superconductor was rotated with a matching counter angular velocity with respect to the moving charge in the superconductor. This is about the charge in the superconductor, not the E field.
