It might seem to be a stupid question..But I really want to figure it out so I posted it here. Again, the problem should be familiar to anyone here. Two lightning bolts strike at both end s of a moving train simultaneously (according to the stationary observer). My question is: In the inertial frame of the train, the lightening strikes at each end of the train will each travel at c to the middle of the train, thus the observer sees a simultaneous lightening strike just like the platform observer. Why this is wrong?
