Why is the speed of light what it is?

Albert Michelson – Edward Morley (circa 1887) tried to establish the fact that an invisible ubiquitous medium called “luminiferous ether” exists. However; when their unsuccessful efforts were determined and hypothesized it became known as the most famous failed experiment in the history of science. The interferometer device that was used consisted of two mirrors which allowed a light source to be split in two orthogonal light beams by a half-silvered mirror such that the beam of light in the direction of motion would arrive a bit slower than the beam arriving perpendicular to the hypothetical ether-wind. When analyzed, the light should have shown up as a distinctive pattern of interference. This turned out to be a null result – there was absolutely no interference pattern. Pressler’s new paradigm shift, perhaps the most important in the history science, is that both mirrors move synchronously towards the center of the interferometer. Particle physicists attest to the supporting empirical evidence – the faster particles are accelerated the smaller they become. The solid space medium is a perfect elastic solid. The M-M theory is a marvelous success.
