New Article[edit]

As nobody knew what Mischner's Room was, and it was really getting on my nerves, I created this page to let the world know it.Orthologist 23:15, 11 January 2007 (UTC)[reply]

I'm concerned about this from [1]

Misner Space - Idea: A 2D space with topology R S1, in which the light cones progressively tilt as one moves forward in time, and has closed timelike curves after a certain point.

which is not whats described here. Especially concerned as its made it to the main page. --Salix alba (talk) 23:40, 17 January 2007 (UTC)[reply]

I've pulled it from the main page, as it seems disputed at best. Yomangani ^talk 01:54, 18 January 2007 (UTC)[reply]

naming?[edit]

Isn't this space just a 3-torus? Lunch 00:07, 18 January 2007 (UTC)[reply]

From the definition in the article yes, but looking at other website I'm not convinced the def here is correct. --Salix alba (talk) 00:29, 18 January 2007 (UTC)[reply]

I wasn't convinced either - I moved it from "Mischner's Room" for which there were zero google hits to this title, but it still looks like mostly original research to me. I'd guess there is an article to be written on Misner space but that what we have here isn't that article. Yomangani ^talk 01:47, 18 January 2007 (UTC)[reply]

anon comment[edit]

I formulated this idea, also! I have a few questions for it, such as:

"What would happen in curved Misner space?"
"How about shrinking, curved Misner space?"
"What would happen if one fashioned an unobtainium reflective sphere in the center?"

Where are the citations?[edit]

Come on. Someone made this up. —The preceding unsigned comment was added by 68.98.152.52 (talk)

Charles Misner is a well-known physicist. However, it would be nice to have a reference for the article that defines the space rigorously (and refers to it as "Misner space"). Lunch 01:41, 18 January 2007 (UTC)[reply]

I've now trimmed this right down to something verifiable. -- The Anome 01:56, 18 January 2007 (UTC)[reply]

Best and most accessible reference is in Hawking and Ellis, "The large-scale structure of spacetime". The Misner spacetime is a simplification of TAUB-Nut spacetime which maintains the main properties. The original reference is Misner (1967). You can look it up on google books. As it currently stands the article is lacking in anything but the barest details. Hawking and Ellis will provide both the necessary math (including the relevant metric tensor) as well as a discussion of it's properties. This spacetime is very important in GR as it is a source of a number of important counter examples. Once tidied up and give the appropriate math I have no doubt this page will be visited often.

References and explanation[edit]

I've added a couple of references and a brief explanation of why the spacetime is of interest. Since this seems to address the concerns raised previously, I've removed the warning from the top of the article.--76.169.116.244 (talk) 01:18, 11 July 2018 (UTC)[reply]
