Re: Imaginary mass? ... since one is effectively dividing by zero....photon must have zero rest mass....particle whose velocity approaches c tends to infinity. ... (sci.physics.relativity)
Re: Q question about relativity ... no. Relativistic mass is not the same as gravitational mass. ... >> for the photon.... >> consistent with zero rest mass.... (sci.physics.relativity)
Re: Q question about relativity ... > The rest mass of a photon is not a physical quantity. ... to have a rest mass value inclusive of zero....energy of a mass, are entirely your own. ... (sci.physics)
