[edit] Relativity

I think that the problems of defining a relativistic version of the rigid body should be mentioned on this page. Several paradoxes in relativity theory stem from this issue (e.g., the barn and pole-vaulter). Ty8inf (talk) 18:26, 7 April 2008 (UTC)

I agree, and more importantly since in relativity one can see that the whole rigid body concept is an ideal approximation that is incongruent with the speed of light limit. Of course without leaving out the fact/concept of rigid motion in relativity (note that rigid motion redirects here), and to mention Ehrenfest paradox. I took the liberty of adding the Relativity wikiproject banner although I'm not a member of such group. Did I do wrong? JunCTionS 00:54, 9 April 2008 (UTC)
