Has the speed of light changed

WebFeb 18, 2001 · The possibility that the speed of light has not been constant has received much attention from physicists, but they have found no evidence for any change. Many different measurements of the speed of light have been made in the last 180 or so years. The older measurements were not as accurate as the latest ones. WebAnswer (1 of 12): If the change is only a small proportion of the current value than we would not notice in everyday life. On the other hand a large change making it only a few times larger than the speeds of everyday objects would make us have to make reletavistic correct calculations. Our se...
