U and V in the Kruskal Diagram

  1. Oct 18, 2012 #1
    I would just like to verify whether or not the variables u and v in the Kruskal diagram are functions of t. Thanks!

    The transformation from Schwarzschild coordinates r, t to Kruskal coordinates u and v is:

    u = -4M e-u/4M
    v = 4M ev/4M

    where u = t - r*, v = t + r*, and r* = r + 2M ln|(r/2M) -1|

    ok, that clears things up, thanks!
