WebAnswer (1 of 102): The universe is not “expanding faster than light speed”. The expansion has no speed. The present-day rate of expansion is approximately 70 km/s/Mpc (Mpc = megaparsec, about 3.26 million light years.) You can derive a speed from this rate, but only once you know the distance b...
