Mr. Ionel Dinu (I assume), Please refrain from posting links to your own papers on all the sites related to ether and gravitational theories. Self-promotion is not the purpose of Wikipedia. Please see Wikipedia:No_original_research#Neutral_point_of_view_.28NPOV.29. If your work needs to be included in the articles, it should be introduced by someone else not connected to the research.

Please refrain from using talk pages such as Talk:Electromagnetic radiation for general discussion of the topic or other unrelated topics. They are for discussion related to improving the article in specific ways, based on reliable sources and the project policies and guidelines; they are not for use as a forum or chat room. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. See here for more information. Thank you. - DVdm (talk) 09:32, 15 April 2020 (UTC)
