 Starting with the equivalence principle, Einstein deduced the phenomena of gravitational time dilation, the gravitational bending of light (albeit with the wrong value ) Einstein's argument that falling light acquires energy To show that the equivalence principle necessarily implies the gravitation of energy, Einstein considered a light source separated along the z‑axis by a distance above a receiver in a homogeneous gravitational field having a force per unit mass of 1 A certain amount of electromagnetic energy is emitted by towards According to the equivalence principle, this system is equivalent to a gravitation-free system which moves with uniform acceleration in the direction of the positive z‑axis, with separated by a constant distance from , and the gravitational slowing of the speed of light .
