Is Dirac's Sea a Dead Sea?

  1. Apr 15, 2012 #1
    Is Dirac's Sea entirely discounted now?

    He did predict positrons - that were later found. And mirrors have been shown to produce photons from a vacuum which is pretty weird.

    There seems to be a flurry of activity in this area of physics caused by computers hitting Casimir Effect problems in sensors that are so small that Casimir forces prevent their perfect functioning. Also as clock speeds increase more of these effects can occur.

    Yes its dead now - QFT has replaced it, makes exactly the same predictions such as antimatter (directly - no sea required) but without the problems of negative mass.
