Special Relativity
Special relativity is Einstein's 1905 framework revealing that space and time are not independent absolutes but form a unified spacetime where measurements of distance and duration depend on relative motion.
Overview
It established that the speed of light is constant for all observers regardless of their motion — a constraint forcing time dilation (moving clocks run slower) and length contraction (moving objects shorten along their direction of travel). The most famous consequence, E=mc², showed that mass and energy are interconvertible, transforming nuclear physics and explaining stellar energy production.
Why it matters
Special relativity fundamentally reshaped philosophy of time and space, replacing Newtonian absolute time with a four-dimensional spacetime geometry where simultaneity is relative. Its practical influence is equally major: GPS satellite clocks must be corrected for relativistic time dilation or navigation errors accumulate to hundreds of meters per day.
