Eek! i'm afraid he's right. the law reads "the speed of light in a vacuum is constant in all inertial frames of reference". the speed of light in anything other than a vacuum is slower. read your physics text. any introductory relativity book will have it. from this one law, all the rest of special relativity is derived.
