Hello, I'm DVdm. Your recent edit to the page Length contraction appears to have added incorrect information, so I removed it for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. DVdm (talk) 07:24, 29 October 2013 (UTC)
