    So, if space expands (measurements gets larger) in the presence of low mass, as between galaxies but not within galaxies, does space shrink in the presence of high mass (measurements between objects get smaller). So who needs gravitons?

    Gravitons are the theorized particle responsible for carrying gravitational force. What do they have to do with expansion in any other way?

    Let's not lose sight of the fact that 'space' is merely the emptiness that separates particles of matter.
