Among today’s physicists, it is doubtful that many would claim that the speed of light depends on the velocity of the source. But it is pleasing to know just how right Einstein’s second postulate in the special theory of relativity is. Recently, by analyzing observations of pulsating x‐ray sources in binary star systems, Kenneth Brecher of MIT has calculated a limit he believes is five orders of magnitude better than past verifications.
