What are Quark Stars?

Carl Anderson found that energy photons split into electron-positron pairs so the energy of the early universe would've done the same so that you're left with a universe full of equal numbers of electrons and positrons i.e. no matter-antimatter asymmetry. Protons and neutrons would've been made from these electrons and positrons so no quarks which means you can't have quark stars. The structure of the proton and neutron would be a nucleus of positrons orbited by electrons with the proton having an excess of 1 positron and the neutron having equal numbers of electrons and positrons. They would combine to form nuclei in the same way as atoms combine to form molecules i.e. electromagnetically. So when further compression beyond the neutron, would be when the electrons within the neutrons collapses onto the positron nucleus. Now you know what happens when electrons and positrons collide - they annihilate each other in a mighty explosion. Maybe that's how black holes explode. There's no mechanism in GR to explain exploding black holes.
