In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Early scientists, unable to perceive lightâs motion, thought it must travel instantaneously.
Lightning is in fact not light. But as the electronic plasma moves through charged air, it releases light waves. Depending on air conditions, the typical lightning bolt moves at 224,000 mph -- or about 3,700 miles per second.However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.+ 125 others found this useful.ight travels at the speed of 186282 miles per sec. According to Einstein it is impossible to go faster or as fast as light because it requires an infinite mass. Right now Ein â¦ steins word is law because there has been nothing to disprove him.
