Hello, I'm Dr Greg. An edit that you recently made to Special relativity seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks!  Dr Greg  talk 01:25, 7 February 2019 (UTC)
