What Is Time — And Why Does It Move Forward?

Imagine you have a box full of colorful balls. If they all start to mix together, it’s easy to tell what happened, like when you drop a glass and it breaks.

Time moves forward because things go from order to chaos, just like balls mixing or a glass breaking.
