Commentary: The author here presented a commentary following a paper by Silvertooth which described an optical experiment claimed to have sensed the Earth's motion at 378 km/s through space. The author's paper discussed the implications and drew attention to the related issue posed by null indication of the 1903 Trouton-Noble experiment.
