Hi all, I have been trying to improve the organization of these pages. No, I don't like the present top of this page either. I am trying stuff out and right now this is the best I can do. I feel that Category:Lorentzian manifolds is not really a parent of Category:General relativity nor vice versa, hence my playing around with "see also". Is there some Wikipedia convention is cases like this to make the two equally venerable but closely related categories parents of each other? If so, this might be a better solution.
Some of you might already have noticed that I have
I also moved the "General relativity" category a subcategory of "Theories of gravitation", and made articles on related theories like "Einstein-Cartan gravity" belong to this category. So, gtr has been "demoted" to just another theory of gravitation, but it is so far the only one which has a category of its own, as befits its extraordinary interest and importance.
(Note: following someone's suggestion, I removed the redundant remarks about certain pages I want to delete.)
While doing the work described above, I noticed that under "Articles in this category", several articles are listed after an asterisk. I also see that "Event horizon" and "Gravitational lens" are listed at the end, after a curly brace. I suspect this might reflect some broken wikicode, but haven't figured out what is causing this.
Hi, Techguru, thanks for your interest in these pages. Einstein said "everything should be made as simple as possible, but no simpler". I feel that the comment you added to the little introductory blurb on this category page, "simply put relativity is stating that time is relative to the observer", was too simple. Much too simple. That's why I removed it. By the way, you typed the first letter of your sentence immediately after the period of the preceding sentence, and you omitted (I think) a comma after "simply put", so in future edits you may want to be more careful about punctuation.--- CH (talk) 18:13, 5 August 2005 (UTC)
I think that the intro has gotten too big. The goal is to explain what this category is about, not to document GR itself. (After all, we have the general relativity article for that.) I would like to shorten it back to about 3 medium length sentences or perhaps 4 short sentences. However, I do not see a good way to do that just yet. (What I am considering doing is pruing everything starting with "In this theory ...". I notice that doing so removes some of my own verbage, but I guess that says something about the utility of that verbage.) -- EMS | Talk 19:03, 7 August 2005 (UTC)
Hi all, I think it is important to distinguish between
Note that the new category Category:Lorentzian manifolds concerns concepts concerning Lorentzian manifolds (four dimensional psuedo-Riemannian manifolds with 1+3 signature), including their interpretation as spacetimes.
Many articles are misnamed, e.g. Gravitational singularity should probably be Curvature singularity, in which case it should perhaps be in the new category.
Some others are a bit iffy:
