Hello, I'm DVdm. An edit you recently made to Special relativity seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. DVdm (talk) 18:22, 8 August 2020 (UTC)

Thank you. Next time I won't do it again. Lumber hydra (talk) 08:56, 10 August 2020 (UTC)
