WebI can't tell you why light travels so fast. I can tell you one interesting thing though. Albert Einstein showed that light is the fundemental speed limit in the universe. Nothing with mass can move as fast as light. Answer 2: This is an interesting question, one I have often wondered about.Light is a complicated phenomenon. WebLight travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross the continental U.S. once in 4 hours. barack obama in australia https://omnimarkglobal.com
