Tensor calculus for general relativity question.

  1. May 23, 2012 #1
    Use the metic that Einstein proposed in the first cosmological model based on general relativity.

    ds2 = -dt2 + (dr2) / (1 - Kr2) + r2(dθ2 + sin2θd[itex]\phi[/itex]2) where K > 0

    Show that the stress energy tensor is that of a static, spatially uniform perfect fluid and determine ρ and p in terms of G and K. If the universe contains only cold matter (denoted by subscript m, with pm << ρm) and vaccum energy (denoted by subscript v, with pv = -ρv), what is the ratio of ρv / ρm?

    could someone help me out? its something I've been working on for a while now and end up in some weird mess.

    Every time I try to compute the curvature tensor, I end up with pages of mathematics that always has an error.

    which part do you get up to ?
