  1. THE ORIGIN AND FATE OF THE UNIVERSE

  2. The Scale of the Universe • The solar system (see illustration)

  3. The Scale of the Universe • Nearby Star systems (see illustration)

  4. The Scale of the Universe • Galaxies • spiral galaxies (the Milky Way and the Andromeda galaxies) • the arms • the central bulge • the halo and globular clusters

  5. The Scale of the Universe (cont.) • Galaxies • irregular galaxies • elliptical galaxies

  6. Large Magellinic Cloud, irregular galaxy M84 Elliptical Galaxy

  7. The Scale of the Universe (cont.) • The Local Cluster or Group (see illustration)

  8. The Scale of the Universe (cont.) • Super clusters (see illustration)

  9. The Scale of the Universe (cont.) • The Universe (see illustration)

  10. Newton’s Model • Infinite and static • Olber’s paradox

  11. Evidence of Expansion • Hubble’s law • doppler shift • recession velocity Vs. distance

  12. Evidence of Expansion • Background radiation • doppler shift

  13. The Creation of the Universe • The big bang • time line • 10-43 s • 10-35 s • 10-35 s - 10-24 s • 10-12 s • 10-6 s • 2 s • 3 minutes • 300, 000 years

  14. The Creation of the Universe • The big bang • the laws of physics • where • when

  15. The Fate of the Universe • Critical mass / density

  16. The Fate of the Universe • Curvature of space • open (saddle or negative curvature) • critical (flat or no curvature) • closed (spherical or positive curvature)

  17. Some say the world will end in fire.Some say ice.From what I’ve tasted of desireI hold with those who favor fire.But if I had to perish twiceI think I know enough of hateTo say that for destruction iceIs also greatAnd would suffice.
