what is speed of light

The speed of light is really fast! It is the fastest thing in the universe and it moves at 186,000 miles per second. That is really, really fast! It’s so fast that if you were to drive a car from New York to Los Angeles, it would take you days, but if you were driving at the speed of light, you could get there in a fraction of a second. As a comparison, if you were on a train going 60 miles per hour, you could get to Los Angeles in about 16 hours. But the speed of light is so much faster that it would take you 0.003 seconds! Fun Fact: The speed of light is so fast that if the sun suddenly disappeared, it would take 8 minutes for us to know it was gone!
