Hello, I'm RA0808. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Dark matter— 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. RA 0808 talkcontribs 16:29, 15 September 2015 (UTC)
