I am once again astonished how fast light is. 3×108m/second. Then, I started wondering what it would be like if people were able to be as fast as light. Using the equation of time=distance/speed I calculated how long it will take for a person with the capacity of running at light speed to finish the marathon. Since a marathon is 42.195km long, it will only take 0.000141 seconds to finish the marathon!!! That person will be able to finish the marathon faster than us blinking and will definitely have the world record that will never be broken. After calculating the time, it was clear how fast 3x108m/s is and once again astonished how fast light travels through space.
