Here's why:
* Gravity is a fundamental force: It's one of the four fundamental forces in nature, along with electromagnetism, the strong nuclear force, and the weak nuclear force.
* Mass creates gravity: Any object with mass has gravity. The more massive an object is, the stronger its gravitational pull.
* Gravity attracts objects: Gravity attracts objects with mass towards each other. This is why objects fall to the ground and planets orbit the sun.
So, gravity isn't found in a particular place, it's a property of the universe that affects everything with mass.
