This theory requires Poincaré symmetry, which includes boosts, rotations, and translations.
This theory requires Poincaré symmetry, which includes boosts, rotations, and translations. The Michelson-Morley experiment confirmed one postulate of it by showing that the speed of light is constant in all reference frames, and it is associated with the twin paradox. It incorporates a factor symbolized gamma that is the square root of one minus beta squared and is only valid in inertial reference frames. Lorentz factors are used for calculations in this theory that predicts time dilation and length contraction. For 10 points, name this theory regarding objects traveling at near-light speeds proposed by Albert Einstein, which is contrasted with its more general form.
