Ive heard that length contraction does not occur when the movement of the object is perpendicular to the observer. Is this correct?(adsbygoogle = window.adsbygoogle || []).push({});

Say two identical rings were travelling at eachother at relativistic speeds, whilst the observer is perpendicular to them. Ring A would see ring B contract and therefore pass through whereas ring B would see ring A contract and go through it. Since both cant contract AND pass through eachother as seen by the perpendicular observer, it does not apply to perpendicular frames of reference.
