Abstract

This paper presents a simple proof of the validity of the universal time postulate on the velocity of light based on the experimental data on stellar aberration observed by Bradley in 1728. It is demonstrated that Einstein's postulate on the velocity of light predicts stellar aberration correctly in coordinate systems in which the star is stationary but fails to predict the phenomenon at all in the earthbound coordinate system in which it is observed.
