If an observer rotates a four dimensional object, the lengths of the object would change to the observer. If that same observer walks backwards, the lengths of the object will also appear to change from his frame. In fact, if either the observer or the object rotates or moves in any way, it will also appear to the observer that the object's lengths have changed. This is very similar to the effects of special relativity in our world.(adsbygoogle = window.adsbygoogle || []).push({});

Here's the question, is length contraction, time dilation, etc, actually just consequences of a fourth spatial dimension?
