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:Variable speed of light are for discussion related to improving the article, not general discussion about the topic or unrelated topics. 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) 07:32, 10 March 2014 (UTC)
Please stop using talk pages such as Talk:Special relativity for general discussion of the topic. They are for discussion related to improving the article; not for use as a forum or chat room. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. See here for more information. Thank you. - DVdm (talk) 08:53, 6 April 2014 (UTC)
