Resumen de Opposite stuff
Cartwright discusses electron-positron plasma, a perfect balance of electrons and their antimatter equivalent. The unique qualities of an electron-positron plasma makes it the ideal test bed for understanding the fundamental workings of more readily available plasmas. The electrons and positrons brought into being after the big bang didn't stick around for long. They cooled and then mostly turned back into photons, allowing protons and neutrons to bind into the first atomic nuclei and producing a gigantic flash of light.
