let's say a train is traveling at relativistic speed along a straight line to right, and a man is standing in the middle of the train.
Both end of the train was installed a gun which aims at the man. The right-ward gun aims at the man's leg and the left-ward gun aims at the man's head.
In the train, each gun shoots a bullet at speed of 0.999c simultaneously. In the train's frame, the bullets will hit his leg and head simultaneously and the man will die.
According to special relativity, however, in the ground's frame, the bullet aiming for the head will travel toward man slower than the other bullet do. Then the man's leg will be hit first, which cause him to fall down (assuming he has enough time to fall), and the head-aiming bullet will then skip the man's head.
Special relativity said both perspective is true. But there are contradictions in the result of events in different reference frames. What is the correct outcome of this thought experiment?
