Speed 

What is the speed of a light? You may ask. Well the speed of a light in a vacuum is 186,282 miles per second which is “299,792 kilometers per second”, and in theory nothing can travel faster than light. In miles per hour, light speed is,well, a lot: about 670,616,629 mph. If you could travel at the speed of light, then you could go around the Earth 7.5 times in one second. As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this exact reason, no normal object can travel as fast or faster than the speed of light. A traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross the Continental U.S. once in 4 hours. There isn’t a man who can beat the speed of light but there is a man who is the fast’s man alive, no man has been born to beat Usain Bolt. In fact Usain Bolt had already broken the world record of 9.69 seconds in history, he set a 9.58 second run at the World championships in Berlin. There is a plot twist, there is to believe that Bolts record will be broken, who knows when but eventually it will be broken. A study is shown that a human being can move up to 40 mph.
