    I How can the stress tensor be non-zero where there is no matter?

    Agreed. Yes I meant the Ricci tensor. My bad and apologies.

    I How can the stress tensor be non-zero where there is no matter?

    This is incorrect. The vacuum Einstein equations are given by ##R_{ab}=0##. The Reimann tensor is zero in vacuum. How could it be otherwise?

    Insights The Einstein Field Equation in a Static, Spherically Symmetric Spacetime

    There seem to be a few errors in the article. ## \partial_{\theta} ## is NOT a killing vector here. I think this is repeated erroneously a few times. Further, ##J(r)## is defined to be the 'redshift factor'. I believe the correct formulation is that the redshift factor is proportional to...
