The experimental and theoretical work of Herbert Ives is presented as a logical alternative to Einstein’s special theory of relativity. Rotational experiments are shown to indicate a light-bearing medium, refuting the foundations of special relativity. The relativity concept of time dilation is replaced by physically produced clock rate reduction when clocks move through the reference medium. The common sense concept of time is upheld as a fundamental quantity of science. The philosophy of relativism is shown to be detrimental to science.
