As I understand it the empty space (vacuum) in a relativistic system contracts as well as the matter. I.e. when a wall traveling at relativistic velocities contracts the whole wall shrinks to a smaller size; the wall does not continue to stay the same length and only the bricks shrink: B=brick S=vacuum BBBBSSBBBBSSBBBB contracts to BBSBBSBB and not BBSSBBSSBB Now the questions I have are... where does the contraction of vacuum end? I.e. 1 meter form the moving object, directly adjacent to the object, or maybe it tapers off? Also, if one area of space contracts does this mean that another area must expand? I.e. if something is contracted by half what now fills the void where it was expected to be?
