Spacetime — A Slender & Hollow Pillar of Physics From Maxwell’s wave equation for EM waves/light, Lorentz inferred an expression (𝑐2𝑡2 − 𝑥2), with its value obviously as zero, that remained invariant in all inertial frames moving co-directionally with the (distance traversed by) light. The theme was
