Talk:Vacuum solution (general relativity)

How to article?

This article has a name which is almost identical to vacuum solution.

I don't want to merge these articles; I want to expand this one and fit it into the new subcategory I just created. I'd like to rename this one Vacuum solution (general relativity). Anyone know how to do this?---CH (talk) 01:18, 27 July 2005 (UTC)

Hmm, just noticed this note from long ago. The move has long since been accomplished, needless to say! Gosh, can't believe I once didn't even know how to rename an article :-/ Thanks again to whoever it was who told me what to do.---CH [[User_talk:Hillman|(talk)]] 20:46, 18 November 2005 (UTC)

Nonexamples added by 192.75.48.150 from Ontario Hydro

Hi, 192.75.48.150, I am always glad to see another fan of exact solutions to the EFE, but the solutions you added

• Reissner-Nördstrom metric
• Kerr-Newman metric

are not vacuum solutions! (Their Einstein tensor does not vanish, except for the special vacuum cases which are already mentioned as Schwarzschild metric and Kerr metric respectively.) Rather, these are examples of electrovacuum solutions.

Request to all editors: please make sure any information you add is correct. If in doubt, try reading articles linked to this one (192.75.48.150, if you'd done that, you would have found Kerr-Newman and friends listed among the examples of electrovacuum solutions.) Even better, study standard textbooks, the half dozen or so review papers on exact solutions, and the "exact solutions book". (See General relativity resources for citations.) If still in doubt, ask here on the talk page. I have this on my watch list, but I do take wikibreaks from time to time, so if you get no response, check my user talk page or ask for advice in the Wikiproject physics discussion page.

Eeep!!! Absolutely right. Sorry. -Dan 20:58, 18 November 2005 (UTC)

Students beware

I extensively rewrote the August 2005 version of this article, which concerns a subject dear to my heart, and had been monitoring it for bad edits, but I am leaving the WP and am now abandoning this article to its fate.

Just wanted to provide notice that I am only responsible (in part) for the last version I edited; see User:Hillman/Archive. I emphatically do not vouch for anything you might see in more recent versions, although I hope for the best.

Good luck in your search for information, regardless!---CH 19:54, 1 July 2006 (UTC)
