Is this new image (below) of polarized light surrounding Sagittarius A, showing actual frame dragging being captured by the magnetic field? The image is from this article If not, how would a photo showing frame dragging in the magnetic field look any different?

I understand that electrons can't cross an open switch, but why don't they at least move towards the open switch when a battery is connected? Doesn't the voltage cause motion towards the positive terminal?

I would be extremely grateful for any help that anyone could offer here. I am interested in solving the optical bloch equations for the excited state population Rabi oscillations with damping due to spontaneous decay. The problem that I have is not solving the equations mathematically, but making...
