What is $ 3 \times 10^8 $ m/s?

3 × 10⁸ m/s is how fast light moves through space, it's super, super quick!

Imagine you're on a playground, and you run as fast as you can to the swings. That’s pretty fast for you, right? Now imagine a superhero who could run a billion meters in just one second, that’s like zooming past thousands of swings every blink of your eye!

• Light moves at about 300 million meters per second, which we write as 3 × 10^8 m/s.
• To put it in kid-friendly terms: If light were a race car, it could go from Earth to the Moon in less than two seconds!
• That’s like going from your house to the park and back, in one second!

So, next time you see sunlight or turn on a flashlight, remember that light is zooming through space super fast, even though we can’t feel it moving. It's like having a friend who can run the whole length of the playground in one step!3 × 10⁸ m/s is how fast light moves through space, it's super, super quick!
