Hello, LeeMcLoughlinScientist, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your recent edits to the page Michelson–Morley experiment did not conform to Wikipedia's verifiability policy, and may have been removed. Wikipedia articles should refer only to facts and interpretations verified in reliable, reputable print or online sources or in other reliable media. Always provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles.

DonFB, thank you for dropping me a line. I didn't cite the edit simply because I assumed my link to Quantum Electrodynamics on Wikipedia would suffice. Kind regards, Lee LeeMcLoughlinScientist (talk) 09:29, 3 October 2022 (UTC)

I claim no expertise in the matter, but am endeavoring to apply Wikipedia practices. The information in the Quantum Electrodynamics article might be seen as supporting your contention, but if it does not contain a claim about the M-M experiment, you would then be engaging in what Wikipedia calls "synthesis"--using one or more sources to support a claim not explicitly addressed in the sources. Also, Wikipedia articles themselves are not permissible as sources for other Wikipedia articles. Sources must be external to Wikipedia and must also be "reliable". If you're new to Wikipedia, also have a look at the policy on "No Original Research". DonFB (talk) 09:50, 3 October 2022 (UTC)

Hello, I'm DVdm. I noticed that you added or changed content in an article, Velocity, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. - DVdm (talk) 21:04, 16 October 2022 (UTC)

Note re [1]: the new version that you proposed, is not supported by the content of the article. The original wording was. Please see wp:LEAD and wp:FIRSTSENTENCE. Thanks. - DVdm (talk) 21:04, 16 October 2022 (UTC)
