243 - What is the speed of light, and why is it important?

The speed of light is approximately 186,282 miles per second (299,792 kilometers per second). That's really, really fast.

It's important because it's the fastest speed in the universe. Nothing can travel faster than light. This speed of light helps us understand how the universe works and how things move. It's also used in many areas like space travel, communication, and even in our daily devices like computers and phones.

Imagine you're sending a text message to your friend on the other side of the world. The message travels through the air using light signals, and because light is so fast, your message reaches your friend almost instantly. That's pretty cool, right?
