> From: Peter Alfke <Alfke.pasa@Xerox.ARPA> > Photons (and anything else which travels at lightspeed) are massless. Photons are not massless! They have energy, and thus they have mass, because mass and energy are the same thing. There's no such thing as a massless particle because anything that carries information, carries energy.
