  1. History of the Universe Chapter 8, Sec. 5 Prentice Hall Science Explorer

  2. What is a “theory”…

  3. The BIG BANG theory 1st - All matter in the universe was in a dense ball. 2nd -10-15 billion years ago the ball exploded. 3rd - Galaxies continue to spread farther apart. • The farther apart the galaxies are, the faster they spread.

  4. Evidence for the Big Bang • Red shift – • http://www.dustbunny.com/afk/skywonders/redshift/ • Left over background radiation

  5. Origin of the Solar System 1st – a cloud of dust and gas formed a spinning disk. 2nd – the gas in the center collapsed to form our sun. 3rd – remaining gas and dust formed planets. - beyond the planets is a belt of ice and dust…the main source of comets. http://www.classzone.com/books/earth_science/terc/content/visualizations/es0401/es0401page01.cfm
