What are your standards for something being 'real'? Science is interested in validating theories. Theories which predict observations are considered validated (or at least not invalidated, to be really picky), and most people use that as a good indication of 'real' (and General Relativity has passed the tests of science multiple times with flying colors). It seems you have a different set of requirements, but you haven't stated them, other than numbers and spacetime don't meet them.
