Hello, I'm DVdm. I wanted to let you know that one or more external links you added to Special relativity have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you. - DVdm (talk) 15:52, 17 February 2021 (UTC)
