Hi guys, I watched a program the other night that got me thinking, just like in the atom when the electron circles but keeps its distance from the proton and neutron, dark matter in the Universe could also be negative anti-matter and 'dark energy' it's anti-gravitational effect expanding the universe. It also explains how 0 + 'the big bang' = +matter and -matter. An expanding apparently seemingly infinite universe of both + and - created from nothing
