Hi, I've been reading some literature on Special Relativity, and even if I think I have more or less understood the relativity of simultaneity, some of its consequences (in the way I have understood it) appear too surprising to me. The problem is similar to the Andromeda Paradox, but seems even more exotic to me. I'll describe the scenario, I'd like to know if I go somewhere wrong to invalidate the conclusion; if not, well... then this is a real consequence of the theory. A crime has been committed on top of mountain X. The police arrives some time later and want to know what happened. A time t1 after the crime they send an unidirectional signal to mountain Y (in the speed of light c or nearly) which is a distance L from X and where there are more policemen. The signal is uni-directional, and it asks to the people in Y to check what happend in X. Of course, X and Y are stationary to each other, they're in the same reference frame S. The world police is organised in a way so there are patrols going around the world in a speed v close to the speed of light. The police in Y wait until one of these patrols passes beside them in the direction contrary to X, they wait t2. When the patrol passes beside them, the folks at Y give the coordinates of X to the patrol. This information exchange is instantaneus as they are both in the same place. The patrol doesn't stop, there has not been any acceleration or decceleration, so we stick into SR only. Now the patrol needs the time t3 to adjust its telescope towards X and so on, and now they look. As the patrol moves away from X, I understand that the patrol, in its reference frame, is seeing the "past" of the X point in the S reference frame. So, considering the desynchronization factor v*L/(c^2) is greater than t1 + t2 + t3, I suppose the patrol could actually see what happened in X at the time of the crime, as even if this is the past in S, it is simultaneous with the patrol in its reference frame. Is this a valid scenario and correct? Can you know what happened in the past asking to check it to a guy in another reference frame?
