# doubt about paradox A relativistic meter stick and a thin disk

based on the paradox resolved at A relativistic meter stick and a thin disk

if in the place of a relativistic stick, was a relativistic man whose length is the same as that of a stick, and instead of an end of a hole, was a bullet. In the man's frame, would he die(Does the bullet effectively hit the man?)? and in the reference of the hole?

By construction in that problem, the center of mass of the man and the bullet coincide at some time. Two objects being at the same place at some time is Lorentz invariant: if two objects are at the same place as one another in one frame at time $t_1$, they are guaranteed to be at the same place as one another in any other frame at some (possibly different) time $t_2$.
