  1. 1. The big bang theory
  2. 2. On the regents… <ul><li>“ Describe and explain 2 pieces of evidence for the big bang theory” </li></ul><ul><li>1. Light from other galaxies is red-shifted. </li></ul><ul><li>2. There’s uniform microwave radiation in the universe. </li></ul>
  3. 4. 1. Electromagnetic waves <ul><li>Stars emit electromagnetic waves </li></ul><ul><li>Stars from distant galaxies emit wavelengths that are red-shifted. (Doppler effect) </li></ul><ul><li>Red shift suggests that all galaxies are moving away from us </li></ul>
  4. 5. 2. Uniform microwave radiation <ul><li>Low-frequency , microwave radiation comes from all directions of the universe. (remnants of the explosive energy from the big bang) </li></ul>
  5. 6. <ul><li>1. Which of the following observations provides evidence for the Big Bang theory? </li></ul><ul><li>A. Galaxies are usually much further apart than the stars within a galaxy. </li></ul><ul><li>B. The galaxies are all rotating. </li></ul><ul><li>C. the galaxies are all moving apart. </li></ul><ul><li>D. The galaxies are all moving closer together. </li></ul>
