An Analysis on Absolute Velocity

Abstract

Jiang Yu

Light travels through a vacuum at speed c regardless of the motion of the light source or that of an observer's frame of reference. Consequently, sometime is required for light to travel from a light source to an observer in space, such that the emission of light and the observance of the emitted light are not simultaneous. Based on these considerations, a method for measuring the absolute velocity of an observer is proposed, which could be used for determining a spacecraft's state of motion from inside a closed cabin. In this study, a new explanation of the Lorentz transformation is also introduced.
