Hello, I'm Gaelan. An edit you recently made to Cosmic microwave background 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. Thanks. (talk to) Gaelan('s contributions) 01:14, 14 October 2017 (UTC)
