  Please do not remove content or templates from pages on Wikipedia, as you did to One-way speed of light, without giving a valid reason for the removal in the edit summary. Your content removal does not appear to be constructive and has been reverted. If you only meant to make a test edit, please use the sandbox for that. Thank you. - DVdm (talk) 13:36, 7 June 2020 (UTC)Reply

Note re [1]: the content that you removed is properly sourced, and our personal opinions about validity of sources are not sufficient to remove sourced content. We can discuss our concerns on the talk page to reach wp:consensus about such changes. - DVdm (talk) 13:40, 7 June 2020 (UTC)Reply
