“Relativity” was a misnomer. Einstein worked his way to a new physics by demanding consistency and greater objectivity of the old. If the speed of light is a constant, then something else must serve as the elastic between two systems at motion in relation to one another—even if that something else is time. If a body gives off an amount E of energy its mass minutely diminishes. But if energy has mass, then mass must have energy: the two must be equivalent: E = mc2, E/c2 = m.632 (I.e., an amount of energy E in joules is equal to an amount of mass m in kilograms multiplied by the square of the
