Please discuss
After you added material to Dark matter, it was reverted, with an edit summary indicating that the material appears to duplicate material already included in the article (at Dark matter). Once the revert occurred, you should not just reinsert the material; instead, you should discuss the matter at Talk:Dark matter. (See WP:BRD.) WikiDan61 ChatMe!ReadMe!! 15:48, 12 November 2019 (UTC)
