That article was very apt and relevant Jack. Notice it confirms what I said, in that they went at it with a false presumption. such as, "they reasoned, then all celestial bodies must have some velocity relative to it. So someone standing on Earth and facing in the direction of its motion through space would have an "ether wind" rushing past their face. According to this thinking, a light wave travelling with the ether wind would seem to move faster than a light wave heading into it. And Michelson and Morley set out to prove this." They assumed the aether was stationary, and everything else moved through it, instead of with it. These modernists in their new experiment have not left any opening to accept a different point of view which contradicts this false assertion. Of course the .rotating aether near the surface cuts through the experiment, not the other way, so even had they detected the miniscule effect, it would prove nothing. But there is the further complication. The speed of the earths alleged movement of 30 kilometres per second arouind the sun can have no relevance if it is non existent. . They did mention 8k per second, detected, fut the equatorial aether speed is 1670k/h is less than 0.5km/sec. So methinks there is something wrong with the experiment in any case. Why move away from a vacuum, and into dense gases? Their argument is of course that the size of the equipment and a reduced wavelength would increase accuracy. I would not trust any measurement outside a vacuum, or outside of a solid which would suit their reasoning. Gases are subject to molecular activity and thus irregular movement even in a constant? ? temperature. . Finally the biggest presumption of all that has no merit in my thinking, is to presume that EMR in an aether medium, which is not a material subject to mechaical law, (other than as proposed in inertia) can be made synonomous with wave motion theory as involved mechanically in the propagation of sound. The aether will not propagate sound. I rewrite the propagation of radio and light another way. Electromagnetic phenomena needs an aether to exist or operate in, but this does not mean that the aether is a "physical medium" that propagates waves in the mechanical sense. Electromagnetic phenomena is not a mechanical entity. It is far bigger than a case of "apples" versus "oranges" An alternating magnetic field at 1000hz IS NOT an alternating pressure wave in a medium at 1000 hz. Their only commonality is mathmatical. It is a mistake to make them analogous in reality. That EMR varies in wavelength and speed in different physical mediums should say something to these people. Philip.
