What are atoms and what is everything made of?
Look at your hand. Now look at the chair, the air, the stars. Here's the wild part: all of it — every single thing — is built from the same tiny building blocks. We call them atoms. And they are so small that if you lined up a million of them, they'd still be thinner than a hair.
An atom is unimaginably small. Imagine blowing up a single apple until it was as big as the whole Earth. Even then, one atom inside that giant apple would only be about the size of a real apple. That's the scale we're playing with.
