The expanding universe

      This is a very nice description. However, the spectra shown to discuss the red shift where blue is next to red and green, yellow and orange are on the other side of blue are incorrect. The color sequence should be blue, green, yellow, orange and then red.

      Very clear and helpful description.I would love to have as equally clear a description of what time actually means in the universe, and how you know the speed of light stays constant (or does it?)while it is traveling?
