E = mc^2. Or Is It? : A Comment on Manuscript astro-ph/0504486
arXiv:physics/0508071
Abstract
Manuscript astro-ph/0504486 is a clear example of the fundamental conceptual flaw that had persisted for the past 100 years. Namely, the failure to realize that mass-energy equivalence, as applied to a propagating light particle (photon), is only a special case of a more general law that encompasses both photons and subluminal particles.
