Orbital Velocities in Expanding Space
In expanding space-time an object will orbit at a lower velocity than in flat space, allowing it to fall back inward due to gravity by a distance equal to the distance it will be swept outward by expansion. In contracting space-time, the object must orbit at a higher velocity, allowing it to rise outward against gravity by a distance equal to the distance it will be swept inward by contraction.
