Relativity and Cosmology


Variable Time and the Variable Speed of Light

Authors: Edward G. Lake

Einstein’s Special and General Theories of Relativity state that time is a variable depending upon motion and gravity. The theories also state that the speed of light is variable. Einstein’s theories are being verified virtually every day. Yet, a few physicists still argue that time does not vary, and many physicists appear to inexplicably argue that Einstein’s theories state that the speed of light is invariable. This is an attempt to clarify what Einstein wrote and show how experiments routinely confirm that the speed of light is variable.
