 Starting with the By the time of his 1911 paper, Einstein and other scientists had offered several alternative demonstrations that the inertial mass of a body increases with its energy content: If the energy increase of the body is , then the increase in its inertial mass is equivalence principle, Einstein deduced the phenomena of gravitational time dilation, the gravitational bending of light (albeit with the wrong value ) , and the gravitational slowing of the speed of light .
