The current rate of expansion of the universe is thought to be about. [math]70[/math] km/s per megaParsec. A megaparsec is a unit of distance approximately equal to three million light-years. This rate is not a speed, it is a speed per distance, so it cannot be compared to a speed (like that of light).
The most obvious explanation is that the universe itself is expanding. Since the universe is expanding, it makes sense that the objects within an expanding universe may expand with it. Since galaxies are embedded in the fabric of the universe, they too tend to move in motions of general expansion (moving away. Expanding Universe. from each other). Energy, gravity, and all of these factors come into play with the rate of expansion, potential for collisions, and so forth.
