Light does not degrade to matter and there are no opposites of any of the forces. The anti or opposite force matter doesn't exist. Mitch Raemsch

You showed me that you are, in fact, stooopid and incapable of learning anything. Incapable of typing something like "positron decay" into Google and actually learning something. Too stooopid to even realize I never claimed isotopes were antimatter. We know the difference between ignorance and stupidity is.
From: Urion on 3 Mar 2010 12:53 Maybe what Burt is asking is why there really are more baryons than anti-baryons in the visible universe? Well there is no simple answer to that question and in fact we don't really know but here's a good place to start: http://math.ucr.edu/home/baez/physics/ParticleAndNuclear/baryogenesis.html http://www.physicsforums.com/showthread.php?t=341918
