Planck scale

Okay kiddo, have you ever heard of the Planck scale? It's a really, really, really small scale that scientists use to understand the tiniest things in the universe.

Think about it this way - you know how small ants are, right? Well, the Planck scale is waaaay, way smaller than ants. It's like ants compared to elephants.

Scientists use the Planck scale to study things like particles, atoms and even the fabric of space-time itself. It's a super important tool that helps scientists explore the universe and all the itty-bitty pieces that make it up.

So there you have it, kiddo. The Planck scale is a super tiny scale for studying super tiny things.
