That's absolutely correct! Every object in the universe, no matter how small, exerts a force of gravity on every other object. This is a fundamental principle of physics.

Here's why:

* Gravity is a fundamental force: It's one of the four fundamental forces in the universe (the others are electromagnetism, the strong nuclear force, and the weak nuclear force).

* Mass creates gravity: The more mass an object has, the stronger its gravitational pull.

* Every object has mass: Even tiny particles like atoms have mass, and therefore they exert a gravitational force, albeit a very weak one.

However, it's important to note that:

* Gravity is a weak force: While it governs the movement of planets and stars, gravity is actually the weakest of the four fundamental forces. This is why you don't feel the gravitational pull of your coffee mug, for example.

* Distance matters: The force of gravity weakens rapidly with distance. The further apart two objects are, the less they pull on each other.
