Imagine you have a big ball and it's holding everything together, like glue. But there's another force trying to push everything apart, like someone blowing up a balloon. The universe stays balanced because the glue and the blow are just right. If one was stronger than the other, we'd either be crushed or stretched out forever.
Examples
- A seesaw balancing two kids
- An apple falling and a balloon expanding at the same time
- A tightrope walker staying steady on a thin wire
