  1. Lecture 17: Force Unification Lecture 18: The Inflationary Universe Astronomy 5: The Formation and Evolution of the Universe Sandra M. Faber Spring Quarter 2007 UC Santa Cruz

  2. Another version with gravity added. Speculative!

  3. Summary slide of unification including times, energies, and temperatures

  4. Unification with supersymmetry: convergence gets better Poor convergence Good convergence

  5. Summary slide of unification adding times, energies, and temperatures

  6. Two giants of modern cosmology Andre Linde: Eternal Inflation Alan Guth: Inflation

  7. The radius of our cosmic horizon today is 14 billion lyr (about 1026 m). This graph shows the physical size of this region back in time. 1026 m soccer ball, <1 m

  8. The radius of our cosmic horizon today is 14 billion lyr (about 1028 cm). This graph shows the physical size of this region back in time. Expands by 1026after inflation. Expands by at least 1050during inflation.

  9. The mathematics of space curvature during inflation resembles that of a balloon. In both cases, increasing the volume of space drives the curvature to flat.
