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).
Stars other than our sun are so far distant that astronomers refer to their distances not in terms of kilometers or miles â but in light-years. Light is the fastest-moving stuff in the universe. It travels at an incredible 300,000 kilometers (186,000 miles) per second. So, in a year, light travels far.
