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).
Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). But some scientists are exploring the possibility that this cosmic speed limit changes.instein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second).
