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).
But all of these things are nothing compared to the speed of light, which is the fastest that something can travel through the Universe. The speed of light is sometimes referred to as the âcosmic speed limitâ. Light travels in a vacuum at 186,282.4 miles per second or 299,792,458 meters/second. For simplicity, it is often said that these numbers are 186,000 miles per second, and 3.00 x 10^8 meters per second.
