Hello, I'm ToBeFree. I noticed that in this edit to Special relativity, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. 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. ~ ToBeFree (talk) 11:45, 31 October 2019 (UTC)
