  1. BUILD YOUR OWN UNIVERSE

  2. SESSION INTRODUCTION Hubble Space Telescope image of a cluster of galaxies. Some appear as they did 12 billion years ago. Image courtesy of NASA/ESA/STScI.

  3. THE FIRST FEW SECONDS T = >100,000,000,000oC Fundamental Particles up quark electron positron neutrino photon down quark antimatter partner of the electron particle of light carry electric charge in circuits found in threes, make up the matter around us interact very little with normal matter

  4. THE FIRST FEW SECONDS T = 3,000,000,000oC up quark up quark proton down quark neutron down quark down quark up quark

  5. THE FIRST TWO ELEMENTS …to make deuterium add another helium-3… …to make helium -3 add another proton… proton becomes a neutron: beta decay add a proton to the new neutron… 1 2 H He …to make helium-4 + two extra protons 1.01 4.0026

  6. 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

  7. TIME = 100 MILLION YEARS Elements heavier than helium are made by fusion in the heart of stars. Image courtesy of ESA.
