The speed of light is so incredibly fast that it is difficult to express it in human terms. But here are some comparisons.
If you could run at the speed of light, you would be able to run around the world seven times in a single second.
If you could run at the speed of light, you could run from one time zone to another in the blink of an eye. You would be able to see ten sunsets in the same evening!
When you are talking on an international phone call, you can say something on the phone. Your call will go up into space to a communications satellite 23,000 miles into space, and back down. And you hardly notice the delay!
