“The Lorentz transformations, when properly understood, are revealing a mathematical relation between mind and matter. Descartes argued that mind is unextended and matter extended, yet can interact with each other. The Lorentz transformations show how this actually works. Light is unextended, and matter is extended, yet matter is wholly defined relative to light, and cannot exist without light. Because light is absolute, it is eternal and necessary. Because matter is relative, it is temporal and contingent. It’s all in the math. The Lorentz transformations mathematically prove that idealism is true and materialism false. Idealism is absolute, and materialism relative (dependent, derived, created, caused)”
