Proof of Buchdahl's theorem?

  1. Apr 9, 2012 #1
    Where can I find an accessible proof of Buchdahl's theorem, which states that in general relativity GM/(c^2*R) must be less than 4/9?

    Any help would be greatly appreciated.

    Thank You in Advance.

    If I remember correctly, Schutz has a chapter (or at least a section) on this. I don't have my copy with me at the moment so I can't check.
