8. You have studied the spectra of four sample galaxies and found that three of the four demonstrate red shift. Astronomer Edwin Hubble discovered that only a very few nearby galaxies are moving toward us, demonstrating blue shift. More distant galaxies are all moving away from us, demonstrating red shift as in this example. What does the red shift indicate?
