What does the jargon repulsive gravity mean in Einstein's GR or even attractive gravity in the same framework? The notions of attractive and/or repulsive only makes sense, or at least we are habituated with those concepts in case of a force or a potential, as in Coulomb's law of electrostatics. It is not obvious what would a repulsive or attractive gravity precisely mean in Einstein's GR. Does attractive (repulsive) gravity mean deceleration (acceleration) of the expansion of space?
These are pop-sci terms. Relativists don't use them because they don't have precise definitions. The precise way to discuss this kind of thing is in terms of energy conditions.
