Ok I was trying to explain special relativity to a friend and I was wondering about something (he said someone explained to him why special relativity was wrong ). Lets say you have 3 people, A, B, and C. Person A sits on earth. Person B is in a rocket ship. Person C is with person A and is observing person A while also watching person B via a 2.4ghz 30 frames per second (FPS) video linkup. Now, person B speeds up to near the speed of light. I forget what speed we had used but i remember y=4. Now I was trying to explain exactly what person C would see on his little tv but I couldn't really figure it out. Would the receiver not pick up anything because of the doppler shift? And if it be adjusted to pick up the correct frequency, would you see everything at 7.5FPS?
