  1. The Big Bang Sam Tipton Justin Matteri Jordan Stone • Physics 4D • Y. Ataiiyan • May 4, 2006

  2. What is the Big Bang • All matter of Universe emerged from single dense hot state • Combination of Cosmological Principals and general Relativity • 13.7 Billion years ago • Giant ball of matter (Nucleosynthesis), Alpher-Bethe-Gamow(1946) • Hubble’s Law (1929) • Red Shift

  3. Supportive Evidence • Abundance of Lighter Elements: Li, H, He, Be • Cosmic Radiation -Cosmic Microwave Background -Proposed 1948 Gamow-Alpher -Proved 1965 Bell Lab • Universe Expanding (Red Shift)

  6. RHIC Facility • Relativistic Heavy Ion Collider • 2-3.7km Rings • BRAHMS, PHOBOS, STAR, PHENIX • Gas filled detector • Gold and other heavy nuclei to 0.99999C • Tests Quantum Chromo dynamics (QCD) • Temps up into the Trillions of degrees

  7. Gas Detector at STAR

  8. RHIC Discoveries • Mini Bangs at 20,000 GeV • 1030 atm and T=5*1015 C • 15 Times energy needed to free quark • Resulting pattern shows fluid like versus gas like. Performs with almost no viscosity.

  9. In the Future • Tracking heavier charm and Beauty quarks • Next step at CERN’s LHC (Large Hadron Collider) in 2008 • Uses lead nuclei at 106 GeV • Will produce temperatures of over 10 Trillion degrees • Uses ALICE detector, with technology from PHENIX and STAR detectors
