%0 Journal Article %T The Dirac Electron in the Planck Vacuum Theory %A Daywitt W. C. %J Progress in Physics %D 2010 %I HEXIS (Arizona) %X The nature of the Dirac electron (a massive point charge) and its negative-energy solutions are examined heuristically from the point of view of the Planck vacuum (PV) theory. At the end of the paper the concept of the vacuum state as previously viewed by the PV theory is expanded to include the massive-particle quantum vacuum %K Plack vacuum %U http://ptep-online.com/index_files/2010/PP-23-17.PDF
