Message-ID: <2306@umcp-cs.UUCP> Date: Wed, 31-Aug-83 17:49:23 EDT Article-I.D.: umcp-cs.2306 Posted: Wed Aug 31 17:49:23 1983 Date-Received: Thu, 1-Sep-83 08:38:18 EDT Organization: Univ. of Maryland, Computer Science Dept. Lines: 9 I don't think it has been shown that there is only ONE speed of light. That is, the average speed of light (average of the north-bound and south-bound speeds) CAN be measured, but the speed of light in a single direction cannot be measured. It is possible that the speed of light is not the same in every direction, no one knows. --Jim
