Hi, I was reading on special relativity and was trying to understand it. However, I am still not very sure about the concepts. For example, I have this problem: I have 2 spaceships, A and B, travelling towards each other. Both have rest length x and speed v, where v is near the speed of light. Both are getting bombarded by photons that travel perpendicular to the direction of the spaceships. The person in A will think "Hmm, due to length contraction, the rate at which he gets hit by photons is smaller than mine" Person B will think the same way. Person C in the observer frame will think that both ships will get hit at the same rate. How do you resolve this contradiction?
