Science is awesome update 5
Having studied the way in which clouds of gas absorb the ultraviolet light from distant galaxies called quasars, some astronomers believe that the pattern of electrons orbiting atomic nuclei have changed slightly over time. This pattern is determined by the fine structure constant, which is a combination of other constants, which includes the speed of light. So, it is possible that the speed if light was faster in the early universe, but dropped quickly to almost its modern value. This conclusion, however, remains controversial. The current speed of light is EXACTLY 298,792.458 km/s.
