Chaos Theory is about how small changes can lead to big changes over time. It's like tiny ripples on the lake. A tiny pebble that causes a small ripple will eventually lead to bigger and bigger ripples coming from the center. The same idea applies to chaos theory. Small changes to a complex system can lead to big changes further down the line. For instance, when a butterfly flaps its wings, it can cause a storm on the other side of the world. That's chaos theory!
