The Lorentz Aether Theory

The Lorentz transformations are best known for the relativistic Lorentz factor, γ = 1/√(1 – v^2/c^2), which appears in the equations of special relativity, and it is also known that the Lorentz transformations can be used to derive both the Biot-Savart law in the form B = γv×E/c^2, and the magnetic force in the form E = γv×B. It could therefore be argued that magnetism is a relativistic effect, even though it is observed at laboratory speeds. This article will now examine how the physical structure of the luminiferous medium enables the existence of magnetism. The aim will be to identify the latent presence of the speed of light within the fabric of a laboratory magnetic field. On establishing this, the Lorentz factor will then be exposed as an asymptotic coefficient which only becomes significant at speeds close to the speed of light.
