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).
Scientists have apparently broken the universeâs speed limit. For generations, physicists believed there is nothing faster than light moving through a vacuum â a speed of 186,000 miles per second. But in an experiment in Princeton, N.J., physicists sent a pulse of laser light through cesium vapor so quickly that it left the chamber before it had even finished entering.
