Here's why:

* Universal Law: Gravity is described by Newton's Law of Universal Gravitation, which states that every particle in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

* No Exceptions: This law applies regardless of where the objects are located in the universe. Whether they are on Earth, in deep space, or in another galaxy, they will still exert a gravitational force on each other.

* Weak Force: While gravity is always present, it is a relatively weak force, especially over short distances. The force of gravity between two people, for example, is negligible. However, over large distances, like the distance between planets or stars, gravity becomes a significant force.

So, the next time you look up at the stars, remember that every star, planet, and even you are pulling on every other object in the universe with the force of gravity.
