Reliable sources

edit

  Hello, I'm DVdm. I noticed that you made a change to an article, Michelson–Morley experiment, 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! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Please note that the sources that you added wih this edit do not qualify as reliable sources on Wikipedia. - DVdm (talk) 06:32, 31 May 2015 (UTC)Reply

Note - See also these responses to your 20 March 2012 question at the new contributors questions help page:
I'm sorry, but Wikipedia is not a place for original research. Furthermore, Wikipedia is not place to publish an article on yourself (see this page). You may want to read what Wikipedia is not. TNXMan 15:42, 20 March 2012 (UTC)Reply
If your ideas have been published in a reliable source (which in this case probably means a refereed journal) then there may be something written on them in Wikipedia: not necessarily an article of their own. If they haven't, then they are not notable by Wikipedia's standard, and as Tnxman says, we do not publish original research. If some coverage is appropriate, WP:WEIGHT and WP:FRINGE may both be relevant to how extensive that coverage should be. --ColinFine (talk) 00:45, 21 March 2012 (UTC)Reply

  Please do not add or significantly change content without citing verifiable and reliable sources, as you did with this edit to Michelson–Morley experiment. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. DVdm (talk) 12:45, 31 May 2015 (UTC)Reply
