Reality of Lorentz contraction: a derivation from non-simultaneous events
Abstract
Abstract A clear and self-contained derivation of the Lorentz contraction formula is presented by applying Lorentz spacetime transformations to non-simultaneous events. The usual textbook approach, which involves a stationary observer making simultaneous measurements of the endpoints of a moving object, is avoided. This alternative derivation highlights that Lorentz contraction arises directly from the geometry of spacetime and not from any particular measurement procedure, emphasizing its physical reality as an intrinsic manifestation of relativistic kinematics.
