  25. I haven't been following along--when did this turn into a science
  26. project?
  27.  
  28. An object that's blue as it approaches and red as it recedes must be:
  29.  
  30. 1. Yellow.
  31. 2. Changing its distance from the observer (the distance along the
  32.    "line of sight") at about 40% of the speed of light.
  33.  
  34. Are we trying to model something like that?
