Talk:Ehrenfest paradox/to do

The artcile is wrong. Rather than misinforming the readership, it should be taken offline until it can be repaired.

I am not familiar with Wikipedia's quality assurance guidelines and policy, and I have not examined the article in depth, but I can see that the top right figure entitled "Ehrenfest's train at 0.6 c..." is wrong (note that the connectors between the box cars along with the box cars would appear to contract since the spacetime, in which both the box cars and the connectors are embedded, contracts - hence the paradox). The text and calculations following the figure are also incorrect, but I don't have the time to correct them. Hence my recommendation. (Softcafe 02:33, 21 October 2007 (UTC))

I'd like to see a resolution of this paradox in some clearer language. In particular, how does a rotating disk appear to an outside observer?
