Interesting reading . . . . Clip from: http://www.calphysics.org/articles/newscientist.html Mass Medium by Marcus Chown published in New Scientist, Vol. 169, No. 2276, 3 Feburary 2001 copyright 2001, New Scientist (posted with permission) “When these particle physicists speak of mass, they are not thinking in terms of inertia or weight. Matter is a concentrated form of energy. It can be changed into other forms of energy and other forms of energy can be changed into matter -- an equivalence embodied in Einstein's famous equation E= mc2. So in this sense, the mass of a subatomic particle is a measure of the amount of energy needed to make it.” Clip from: http://qed.sbytes.com/quantum-field The Quantum Electric Field “This interpretation implies an interesting comparison between a virtual photon and an observable photon. The momentum of an observable photon is given by the planck constant divided by the wavelength. The virtual photon's momentum is much less, (for equal wavelengths), being reduced by the factor alpha over 2PI, or 1/861.”
