THE FIRST FEW SECONDS T = >100,000,000,000oC Fundamental Particles positron neutrino up quark electron down quark photon antimatter partner of the electron particle of light found in threes, make up the matter around us carry electric charge in circuits interact very little with normal matter
THE FIRST FEW SECONDS T = 3,000,000,000oC up quark up quark proton down quark neutron down quark down quark up quark
THE FIRST TWO ELEMENTS 2 He 4.0026 1 to make deuterium H 1.01 add another helium-3 to make helium -3 add another proton proton becomes a neutron: beta decay add a proton to the new neutron to make helium-4 + two extra protons
THE BIRTH OF NEUTRAL ATOMS charge = +1 charge = -1 Cosmic background radiation imaged by the Planck satellite. Image courtesy of ESA/NASA overall charge = 0 overall charge = 0
TIME = 100 MILLION YEARS Elements heavier than helium are made by fusion in the heart of stars. Image courtesy of ESA.
