An experiment recently reported by Silvertooth has provoked much discussion, because he originally interpreted its result as delivering a fatal blow to standard relativity theory. The experiment provides an optical measurement of a velocity, which he took to be an absolute linear velocity with respect to an ether of space. The present author believes the experiment indeed measures a velocity, but that it is not necessarily an absolute linear velocity with respect to an ether; instead, it may be a velocity of rotation relative to a center of rotation.
