Hello, I'm DVdm. I noticed that you made one or more changes to an article, Length contraction, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. - DVdm (talk) 18:23, 20 May 2018 (UTC)

Note: also, please be aware that Wikipedia is not a place where we publish original thought, let alone our own work. See WP:NOTFORUM and WP:COI, and while you're at it, WP:FRINGE - DVdm (talk) 18:28, 20 May 2018 (UTC)
