At present, the article describes the Newtonian gauge in a way that a specialist can understand. As regards it's status as a Wikipedia article, it is rather poor - this is not meant as an insult, rather, it discusses vector and tensor perturbations and it's not clear what significance this has to the the concept of a Newtonian gauge. True, links are given to the technical terms, but the article needs to be cleaned up to give the general (relativity) reader the main gist of the idea and then discuss it's significance, use, limitations (?) etc. in GR. Related to this, it is clear that only an expert is likely to improve this article to satisfy the above criteria. Therefore, I think the tags should remain. MP (talk) 08:00, 13 February 2006 (UTC)
It's not clear to me why vector and tensor perturbations are discussed anyway-- it should be sufficient to say that only scalar perturbations are being considered. Still, I've changed the statement on the tensor perturbation to highlight the fact that the first order tensor perturbation is really gauge *independent*. Ajcz ( talk) 10:01, 18 October 2009 (UTC)
I'm pretty sure that it's Psi not Phi that is the Newtonian potential. Also, different authors use different sign conventions on Phi and Psi.
