Actually, two objects far enough apart in the universe could be separating from each other at greater than the speed of light because the expansion of the universe is not subject to the speed of light limitation. However, objects can not move within the universe at greater than the speed of light. (imagine yourself on an expanding balloon. You're speed of running on the surface is only so fast, but the balloon can expand so rapidly that points on it's surface grow apart faster than your running speed. Now convert this analogy to our living dimensions!)
