At a critical point in the development of modern physical theory, two brilliant and dedicated scientists, Albert Michelson and Edward Morley, conducted experiments to measure the velocity of the ether, which was presumed to fill all of space and serve as the medium for the conduction of light.

Their measurements suggested that the velocity was zero, relative to the earth. Either the earth was the center of the universe (as Ptolemy believed) or light was not conducted through such a medium. The velocity of light was clearly demonstrated to be independent of the observer's...

More Light on the Expanding Universe explores the ramifications of the existence of a fourth physical dimension into which the universe is expanding. One of these is the possibility that light travels at infinite speed from the source to any receptor anywhere, rather than at the 300,000 Kilometers per second generally accepted by contemporary physicists. This resolves many of the paradoxes in present-day physics, and simplifies many of the complexities associated with Einstein's special theory of relativity.

In More Light on the Expanding Universe, Les Hardison, now retired from a...
