Can One-Way Light Speed be Measured? Comment on E. D. Greaves et al., Am. J. Phys. 77(10), 894-896 (2009)
arXiv:1003.4964
Abstract
The convention dependence of one-way light speed is explained in a manner accessible to those unaccustomed to the concept. That logic is used to challenge the claim by Greaves et al that their experiment detected one-way light speed. The reason for the result obtained is then presented and followed by an explanation of why the Romer experiment did not measure a convention independent one-way light speed.
