Energy Equals Mass: Why c² is a Human Invention
Energy Equals Mass: Why c 2 is a Human Invention, Not a Universal Law Or: Why E = m c 2 Becomes E = m in Natural Units It is Albert Einstein’s most famous equation in human history: E = m c 2 It states that mass and energy are fundamentally the same thing. But there is a deep cosmic secret hidden inside this elegant formula. The speed of light squared ( c 2 ) isn't actually a fundamental feature of the universe's underlying physics. Instead, it is a mathematical artifact – a conversion factor required solely because of how humans chose to invent our systems of measurement. If we rewrote our physics textbooks using the universe's own logic, that c 2 would vanish entirely, leaving us with the deeper truth: E = m 1. The Physical Invariant: Spacetime's Absolute Speed Limit To understand why c 2 is there, we first need to separate the underlying physics from human accounting. The universe is governed by Einstein’s theory of Special...
