Hello, I'm Serols. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Speed of light— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Serols (talk) 14:21, 29 December 2015 (UTC)

Please stop your disruptive editing. If you continue to vandalize Wikipedia, as you did at Speed of light, you may be blocked from editing. Favonian (talk) 14:31, 29 December 2015 (UTC)
