对这一结果的通常解释是:当由运动观察者观察时,杆的长度会发生收缩,这一效应称为洛伦兹–菲茨杰拉德收缩(Lorentz–Fitzgerald contraction)。通过交换与的角色,同样可以发现,运动的杆在其运动方向上发生收缩。这一效应的关键在于,根据同时性的相对性,杆两端历史中相对于同时的事件对,与参考系中的同时事件对不同。由于在垂直于运动的方向上没有收缩,运动的体积将发生收缩

The common interpretation of this result is that the length of a rod is contracted when viewed by a moving observer, an effect known as the Lorentz–Fitzgerald contraction. By reversing the roles of and it is similarly found that a moving rod is contracted in the direction of its motion. The key to this effect is that, by the relativity of simultaneity, pairs of events on the histories of the ends of the rod that are simultaneous with respect to differ from simultaneous pairs in the frame . Since there is no contraction perpendicula to the motion, a moving volume will undergo a contraction
