==Paradoxes==
Due to superficial application of the contraction formula, some paradoxes can occur. Examples are the [[ladder paradox]] and [[Bell's spaceship paradox]]. However, those paradoxes can be solved by a correct application of the relativity of simultaneity. Another famous paradox is the [[Ehrenfest paradox]], which proves that the concept of [[Rigid body|rigid bodies]] is not compatible with relativity, reducing the applicability of [[Born rigidity]], and showing that for a co-rotating observer the geometry is in fact [[Non-Euclidean Geometry|non-Euclidean]].
