You will be able to calculate the ambient temperature corresponding to the mass-energy of particle reactions. You will know that at different temperatures, the Universe undergoes various transitions: electroweak transition, quark confinement, proton-antiproton annihilation, neutrino decoupling, and electron-positron annihilation. You will know that the electromagnetic, weak, and strong forces were once unified.
