Vacuum Energy Form (aside from gamma rays)

  1. Jul 27, 2011 #1
    So apparently vacuum energy is created and destroyed within planck time by matter, antimatter annihilation. If someone could theoretically stop or slow down time, would it be possible to tap into vacuum energy? Since annihilation creates gamma rays, I suppose vacuum energy would face the same problems nuclear energy is facing. Is there any other way to get this energy besides in gamma ray form?

    Where did you read this?

    For example, in the electron-electron interaction by the exchange of a virtual photon, can you show me where is this "matter-antimatter annihilation"? Look at the Feynman diagram for this process.

    http://en.wikipedia.org/wiki/Antimatter

    first paragraph, last sentence.
    i guess they also produce other particle, antiparticle pairs but i'd imagine they would annihilate each other as well within planck time.

    That wikipedia article has nothing to do with "vacuum energy". Vacuum energy is the vacuum fluctuation, whereas matter-antimatter out of pair production has NO RESTRICTION on its lifetime! If it does, then we wouldn't be using it to generate positrons for particle accelerators.

    Please pay attention to the terminology that you're using, because you're mixing different things into one.

    Zeline: Welcome to Physics Forums....lots of nowledgeable people here....

    Nobody currently knows how to tap into vacuum energy. But it might be theoretically possible to tap similar energy outside a black hole horizon...but right now that's science fiction.

    You might want to read about dark energy, the theoretical energy that causes space itself to expand. Wikipedia says dark energy and vacuum energy are "equivalent"...I'm not sure anybody knows that for sure....but they do seem closely related.

    vacuum energy involves virtual particles....it's not created by matter, antimatter annihilation.

    if interested try reading about virtual particles and vacuum energy in Wikipedia as a start.
