Tests of GR for non-vanishing T

  1. Apr 12, 2014 #1
    My question is the following: Have there ever been any experimental tests of the Einstein equation (a.k.a. Einstein field equations) for the case of non-vanishing energy-momentum tensor?
    If so, which ones?

    I know there's a wikipedia article about tests of general relativity and I have already employed the search function here and of course google, but couldn't find anything specific.

    Cosmology. Neutron stars.

    Thank you for your answer. I suppose you mean the following corresponding metrics
    • FLRW metric
    • Reissner-Nordström/Kerr-Newman metric
    Does the latter imply that Einstein-Maxwell theory should be considered a theory as opposed to an hypothesis?
