Oxford, U.K.--A pair of British astronomers say they have found the best evidence yet for a controversial claim that the speeds at which distant galaxies are receding from Earth are "quantized"--all are multiples of one fundamental velocity. In standard cosmology, there's no reason why these speeds, the result of the expansion of the universe, should be quantized. But a study of more than 200 galaxies revealed that their velocities clustered strongly around multiples of 37.5 kilometers per second. Other astronomers are intrigued but cautious.
