Re: Basic Science Question - "fabric" of space

Well, in the end it's all wibbly-wobbly, timey-wimey, isn't it.

ETA: The real, real problem is that we don't have a theory of quantum gravity. Such a theory would of necessity have to ditch the equivalence principle of General Relativity (that inertial mass and gravitational mass, if not the same thing, are always in the same proportion for no obvious reason). Experiment suggests that the equivalence principle is correct to a very high degree of accuracy, but others have suggested that the observed deceleration of space probes leaving the Solar System, and the anomalous rotation of the outer parts of galaxies result from non-equivalence rather than from dark matter or other "here be dragons" explanations.
