Gravity never stops. It's a force that acts between any two objects with mass. The strength of gravity depends on the masses of the objects and the distance between them.

Here's what happens as you go higher:

* Gravity weakens: The farther away you are from the Earth, the weaker the gravitational force becomes.

* Never truly zero: Even if you were infinitely far from Earth, you'd still feel a tiny gravitational pull from other objects in the universe.

So, there's no specific height where gravity stops. It just gets weaker and weaker the farther you get from the source of gravity.
