How fast does light move
Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The first extant recorded examination of this subject was in ancient Greece. The ancient Greeks, Arabic scholars, and classical European scientists long debated this until Rømer provided the first calculation of the speed of light. Einstein's Theory of Special … Web1 sep. 2016 · Light travels at a constant speed of 1,079,252,848.8 (1.07 billion) km per hour.
