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#Galaxy rotation curves). 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)
