Gravity is a force, but it's not quite as simple as saying it pulls things together.

Here's a more accurate explanation:

* Gravity is a force of attraction between any two objects with mass. So, yes, it does pull things together.

* The more massive the objects, the stronger the gravitational force. This is why you feel the pull of Earth's gravity, but you don't feel the pull of a small object like a book.

* The closer the objects, the stronger the gravitational force. This is why you feel the pull of gravity more strongly when you're standing on the ground than when you're in an airplane.

However, gravity is more than just a force. It's also a curvature of spacetime. This means that massive objects like planets and stars actually warp the fabric of space and time around them. This warping is what causes objects to move towards each other, creating the effect of a pull.

So, while it's accurate to say gravity pulls objects together, it's a more complex phenomenon than just a simple force. It's a fundamental aspect of the universe that shapes the movement of everything from planets to galaxies.
