How Does Space DOES NOT Expand Everywhere Work?

Space doesn’t expand everywhere like a balloon blowing up, it only expands between things that are far apart.

Imagine you're playing with toys on a trampoline. If you drop a ball on the trampoline, it makes a dent and bounces around. Now imagine there are other balls too, each one making its own dent. When the trampoline stretches out, the balls move away from each other, but only if they're far apart.

Big things, like galaxies, are like those balls on the trampoline. They’re so far away that as space expands, they seem to be moving away from each other, just like the balls on a stretching trampoline.

But small things, like your toys or even you and your friend playing nearby, don’t feel this stretch at all. You're close enough that you can still throw a ball back and forth without noticing anything weird happening.

So space expanding is more like a slow stretch, it happens between big things far away, but not right next to you. It’s the universe growing up, just not where you are! Space doesn’t expand everywhere like a balloon blowing up, it only expands between things that are far apart.
