Sorry MaJoC but the asymmetry between matter and anti-matter is simply that. As far as I know "every action has an equal and opposite reaction" does not have an equivalent "every thing has an equal and opposite thing". Do we know that something "broke symmetry" or has there never been perfect symmetry in the natural universe? I understand that this is theoretical physics and is fascinating to some but to sell theory as fact is misleading and that is what I am trying to point out.
