This physical theory uses analogues of rotation matrices containing hyperbolic trig functions. A common derivation in this theory that uses the Pythagorean theorem considers light bouncing between two mirrors. (10[1])In this theory, (-5[1])the integral (10[2])of gamma dt over c equals the (10[1])proper time. (10[1])Lorentz transformations convert (10[1])four-vectors between inertial reference frames in this theory, which holds that simultaneity depends on your reference frame. This theory predicts that moving objects experience time dilation and length contraction, (-5[1])and it was developed (10[1])in one of the “annus mirabilis” papers. For 10 points, name this theory of Albert Einstein that he expanded into a “general” form. ■END■ (10[1])
