Welcome to Wikipedia and thank you for your contributions. I am glad to see that you are discussing a topic. However, as a general rule, talk pages such as Talk:Relativity of simultaneity are for discussion related to improving the article in specific ways based on reliable sources and the project policies and guidelines, not for general discussion about the topic or unrelated topics, or statements based on your thoughts or feelings. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. Thank you. - DVdm (talk) 16:36, 11 December 2019 (UTC)

Note: also please be aware that Wikipedia does not accept wp:original research. - DVdm (talk) 16:40, 11 December 2019 (UTC)

Please do not add or change content, as you did at Length contraction, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. DVdm (talk) 10:25, 8 February 2022 (UTC)
