Something to do with space being time 0.o

  1. Mar 17, 2009 #1
    Can someone explain to me how you can spatialize time, and why can't you temporalize space? Also, why is the spatailization of time only temporary and why can it involve only one dimension of space at a time?

    I've just been doing a bit of reading at this came up.

    I may have, however, completely misread the paragraph, and what I just asked may have made no sense whatsoever. Here it is:

    Thanks for any help (:.

    Hi Mr.Matt! Welcome to PF! :wink:

    Your quote is from an article by Paul Davies at http://www.fortunecity.com/emachines/e11/86/big-bang.html [Broken] …

    it's explained by the previous paragraph (my italics) …
    … though I've no idea what he's talking about :redface:

    Thanks for answering (:

    I had read the article and I understood most of it until this part (:

    I can understand what he's saying in that paragraph, but to me that tells me that it does rather than why it does (:.

    Distance in 4D euclidean space is defined as S^2 = x^2 + y^2 + z^2 + t^2
    Distance in 3D+T Minkowsky space is defined as S^2 = x^2 + y^2 + z^2 - t^2
    Now define distance as S^2 = x^2 + y^2 + z^2 + Kt^2
    Changing K from -1 to 1 you can gradually get rid of time, converting it into space, you switch it back :)

    Oh wow 0.o. That's actually a lot more simple than I thought it would be. I was expecting, like, a page long equation or something (:.
