- Different results unless you are careful?
My questions is:
Depending on which metric you choose "east coast" or "west coast", do you have to also mind the sign on the cosmological constant in the Einstein field equations?
[tex] R_{\mu\nu} - \frac{1}{2} R g_{\mu\nu} \pm \Lambda g_{\mu\nu} = \frac{8\pi G}{c^4} T_{\mu\nu}[/tex]
For example, if you stick with a +Lambda term with both metrics, you get different results for each metric. So once you choose a metric, you have to have the right sign on Lambda it seems.
