Imagine you're in a big, empty room, that's like space. But even though it looks empty, there are tiny things floating around in it, like dust and gas. These things are too small to see with our eyes, but they make up the space composition, what space is actually made of.
Think of your bedroom as Earth. Space is the giant room outside your window, filled with tiny invisible stuff that we can only see if we use special tools.
Examples
- It’s like your bedroom being full of tiny dust particles you can’t see unless you use a flashlight.
- You might think you're floating in nothingness, but there are invisible bits of matter following you like ghosts.
