Classically, any bound system possesses negative energy, since any attractive potential energy is negative. In relativiistic quantum mechanics, Dirac discovered negative energy states, which must completely filled all the way down to negative infinity due to the Pauli Exclusion Principle. When one of these negative energy electrons becomes excited to postive energy, it leaves a hole in the negative energy states. The hole is interpreted as an antiparticle and the positive energy particle is an ordinary particle. Thus we have pair production. Dirac's model was basically the beginning of modern quantum field theory, but left a bit to be desired further down the road.

From: spudnik on 7 Apr 2010 14:29 nah, it's just some math; the French use it, in place of "centroid" or "center of gravity" (actually, "isobarycentre"). and, remember, antimatter produces teh same kind of light waves; such a realization kind-of puts the question too the whole idea of a "photon;" eh? nor is there necessarily any need for "negative energy!" > A barycenter is a zone or volume of negative gravity. --Light: A History! http://wlym.com http://21stcenturysciencetech.com http://white-smoke.wetpaint.com

And a barycenter is a region where all forces balance. Maybe you could look up your terms before making a complete fool ou of yourself. |
