Hello, I'm Lugia2453. I wanted to let you know that I undid one of your recent contributions, such as the one you made to Gravitational constant, 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, Lugia2453 (talk) 02:02, 22 October 2012 (UTC)
