In an infinitely large universe, the net force of cosmic gravity would be 0.<p>Kind of like how an real number divides the number line into &quot;same size&quot; infinite intervals.<p>Granted, entropy in the system would cause matter to clump into larger and larger bunches. But if the matter were perfectly arranged by an outside force (e.g. God) and didn&#x27;t deteriorate, the universe could remain static.
