  1. In the Minkowski geometry, there is no such thing as a relative speed greater than C. What about the blue-shift effect? For me, those 2 things are somewhat contradictory. If I interpret it correctly, the blue-shift effect is created because the speed at which a given object approaching the observer is added to the speed of light. Which means that the relative speed of light beam is greater than C relative to the observer? Am I wrong?
  2. It is a well-known fact that the universe is expanding. This means that the farther we look in the universe, the farther speed away the objects there are from us. In this case, based on the Doppler Effect, the frequency of electromagnetic waves will be slide in a lower region. This means that when you look at to a certain distance with the optical telescope, the colors shift, because of the Doppler Effect. Red going to be yellow, yellow will be green, etc., and magenta slides to UV (Ultra-violet). It is not a major problem. However the visual will be false.
  3. Can someone give a meaningful explanation that the relative speed of two oppositely directed light beams is why only one light speeds? I understand that based on the Einstein relativity theory, the relative speed of two beams is C, because nothing can be quicker than light speed. However it is not an explanation, because based on Euclidean geometry, their relative velocities should be 2C. It seems a paradox, because the two rules give different result. Is there explanation that resolves this contradiction?
