October 2020 edit
Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Mass–energy equivalence, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. DVdm (talk) 11:59, 20 October 2020 (UTC)
Please do not add original research or novel syntheses of published material to articles as you apparently did to Mass–energy equivalence. Please cite a reliable source for all of your contributions. Thank you. Dr Greg talk 12:53, 21 October 2020 (UTC)
Please stop your disruptive editing. If you continue to violate Wikipedia's no original research policy by adding your personal analysis or synthesis into articles, as you did at Relativistic momentum and Relativistic mechanics, you may be blocked from editing. - DVdm (talk) 11:53, 30 October 2020 (UTC)
Please stop your disruptive editing. If you continue to use talk pages for inappropriate discussion, as you did at Talk:Lorentz factor, you may be blocked from editing. - DVdm (talk) 11:53, 30 October 2020 (UTC)
You may be blocked from editing without further warning the next time you violate Wikipedia's no original research policy by inserting unpublished information or your personal analysis into an article, as you did at Relativistic momentum. - DVdm (talk) 16:00, 15 November 2020 (UTC)
