Hello, I'm Petrb. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Alcubierre drive— 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. Petrb (talk) 20:34, 25 April 2015 (UTC)
