“The Lorentz transformations unambiguously show that Cartesian dualism is compatible with mainstream science, except this is not true dualism at all. The true reality is the absolute reality of frequency, of light, of mind, of c. The derived reality, the conditional, contingent reality is the relative reality of spacetime, of matter, of v. Therefore, idealism is true, and idealism can fully explain materialism. The reverse cannot be accomplished. Relative materialism cannot explain absolute idealism.”
