The primary assumption of Einstein’s Special Relativity is that light approaches all observers at a constant velocity regardless of the observer speeds or directions. To test this theory, 100 years ago, and many times since, scientists have compared the velocity of light coming from the direction that the Earth orbits the Sun (30 km/second) with the velocity of light coming from the opposite direction. While the speed should be 30 km/sec faster in the direction of the orbit and 30 km/sec slower in the opposite direction, they found that the speed only varied by about 8 km/sec and this difference was not in the direction of the Earth orbit. The small speed difference in the wrong direction led scientists to assume they were only seeing noise in the experiment apparatus, so they rounded the results to zero km/sec and pronounced Einstein correct that light has only one speed for observers with different velocities.
More recently, scientists have discovered the Cosmic Microwave Background Radiation (CMBR), which comes from all directions, but 365 km/sec faster in the direction of the constellation Leo at 11 hours sidereal time. If light is carried by an “aether” that adds to its velocity, the Earth must be moving through the aether toward Leo at 365 km/sec. However, the aether would be a gas that compresses in Earth gravity, just like air, slowing the ether speed seen on the Earth surface to much less than 365 km/sec, and slowing the Earth orbit velocity far below 30 km/sec, as experiments demonstrate.
The detailed data in all the experiments that are believed to prove Relativity show undeniably that the 8 km/sec measured in the experiments moves in the direction of the constellation Leo, the CMBR direction. This can only mean that light is carried by an aether through which the Earth moves, disproving Special Relativity. More details and many other experiments disproving Relativity are in the book on the first 33 pages of Chapter 4.
