Problems in science today lie in the definition and understanding of zero and color.
Reference is the question.
We have created a celestial coordinate system to explore the heavens. As astronomers look to these heavens they observe a red shift or Doppler effect. The indication is that the more distant an astronomical body is from us, the faster it is receding away from us. In truth, the limits of our perceiving powers tell us that our observational edge is traveling away from us at close to the speed of light. This belief or fact can have real applications in our world.
