Why Physics Needs the Ether - Part 4: Ether and the Electrodynamics of Moving Bodies
This Part 4 of a series of papers, entitled ?Why Physics Needs the Ether?, discusses the electrodynamics of moving bodies and Special Relativity Theory. It offers arguments supporting Stokes theory of complete dragging of the ether by Earth\'s orbital motion. It advocates a research program to carry out Michelson-Morley experiment on a space ship. It suggests that an ether drift may yet be discovered.
