    Please forgive a (no nothing) from what i have understood, if enough energy
    is poured into the vacuum, a particle can (emerge) is this particle given
    existence, or is it drawn across some divide, sorry if this has been done to
    death some where before.

    A pair of particles can appear; you have to obey all conservation laws, so you have to produce particle-antiparticle pairs so as to average out the charge increase to zero. This has been used as a (not exactly right) explanation of Hawking radiation.

    Thanks SA, when you say appear, does that mean they are created?

    Yeah, but under regular circumstances they must recombine and anihilate within a short period of time.

    This is a difficult question, as the created particle/antiparticle tends to seek a quick union with each other, therfore both "poofing" out of existance not long after creation.
    Of course, NATURE provided some unknown mechanism for particle creation stability during the stages of the "Big Bang" or whatever flavor of creation one ascribes to.
    I would venture to guess that during original "creation" that there were much more anihilations than stable "offshoots", but enough "stability" to create what we have now.

    Google "dirac sea". That should correspond to your "drawn across some divide".
