I've studied in many books, from which I learnt that a vacuum is not truly a vacuum, that is, virtual particles are created every time. And I had also learnt that the universe is left handed, that is a small non obeying in parity symmetry(individually), resulted in production of around one in a billion matter particles in matter-antimatter decays, while everything other decayed, during the early stages of universe. And now we're here, in a universe that is like it is. And my point point is, are there any left handedness in the virtual particle interactions(like the one above), if so shouldn't it constantly produce matter particle? Am I misunderstood?
