Hello, I'm Pmokeefe. I noticed that you made a change to an article, Global Positioning System, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Pmokeefe (talk) 12:26, 4 February 2017 (UTC)

Please do not add or change content, as you did at Dark Matter and Projective geometry, without citing a reliable source using an inline citation that clearly supports the material. The burden is on the person wishing to keep in the material to meet these requirements, as a necessary (but not always sufficient) condition. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you.

Note: Please note that attaching the string "General Projective Relativity (GPR) Principia 2.0" to your contibutions does not count as providing a wp:reliable source. Also please stop promoting your self-published work, as you have been doing in all your edits up to now. Continuing to try to promote your wp:FRINGE wp:original research in articles will be treated as spamming. Thank you. - DVdm (talk) 13:47, 4 February 2017 (UTC)
