Speed> Light is always on the move. Yet flip a light switch, and whoosh! The whole room seems to light up at once. Try as you might, you can’t see light travel from the bulb to the wall.
I think I know why. Remember this amazing number: 186,282 (or 299,784). That’s about how many miles (or kilometers) light can travel in one second. Say: “Blaze is brilliant.” That takes about one second.
Suppose I could travel at light speed. I would circle the equator almost seven and a half times in one second. Light is the fastest known thing in the universe. Nothing can catch up with it. Not even close!
Even if you’re waiting for light to travel all the way from the sun to you, you would only have to wait a few minutes. Unless you live on Pluto, that is!
