WP:Secondary sources needed
Hello, I'm DVdm. I noticed that you made a change to an article, Michelson–Morley experiment, 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) 19:04, 27 January 2018 (UTC)
