Category talk:General relativity

http://en.wikiversity.org/wiki/Category:General_relativity

I disagree with the approach of the previous version that "It seems simpler to consider it as an imaginary number ict where i is the quadratic root of -1 and c the speed of light. Then the space-time has the following four dimensions: (x,y,z,w=ict)." Instead, I think that introducing imaginary time only confuses lots of people.

I plan to replace other sections too. -- Schmelzer 22:19, 3 February 2008 (UTC)

namespace conventions

The contents of this page will need to be moved. Pages in the Category: namespace should only contain a list of pages, and not text. We should probably copy (ie. merge) the text to General relativity or to a new page, and then Category:General relativity should be left empty. (No redirect) --mikeu ^talk 22:40, 3 February 2008 (UTC)
