How Does Gravity Shape the Universe?

Gravity is like a big invisible rubber band that pulls everything together, even things as huge as stars and galaxies.

Imagine you're holding two magnets. They pull toward each other, right? Gravity works kind of like that, but instead of magnets, it's the mass of objects, how heavy they are, that makes them pull on each other.

Think of a ball rolling down a hill. The hill is like Earth, and gravity is what makes the ball move toward the bottom. In space, planets and stars act like big hills. They pull things, even other planets! That's why the Moon goes around Earth, and Earth goes around the Sun.

When there are a lot of heavy things in one place, like stars or gas, gravity pulls them together to form galaxies, giant groups of stars. And if gravity gets really strong, it can even make black holes, where everything gets pulled in so tight, not even light can escape!

So gravity is like a friendly giant who loves to bring things together, from little balls on hills all the way up to whole galaxies! Gravity is like a big invisible rubber band that pulls everything together, even things as huge as stars and galaxies.
