While i was thinking about gravity a question knocked in my mind, that whether the gravity outside the Earth atmosphere is precisely zero or a value lesser than that of Earth gravitational force.

    When you move away from an object in space its gravitational pull keeps reducing exponentially and never is zero. While it reduces, the gravitational pull to another object increases exponentially. So, gravitational force is relative and hence cannot be zero.

    Gravitational force exists between any two masses - no matter where you are. It's directly proportional to the product of masses and inversely proportional to the square of the distance between them.

    To explain it in easier words - your computer's mouse and keyboard have a gravitational force between them.

    PS: I'm not quite sure if the force continues to follow the rule under mobile frame of reference. When I get into such doubts, I always check with #-Link-Snipped-# . Sir - is the statement 'Gravitational Force Exists Between Any Two Masses - No Matter Where They Are' correct?

    Right you are on the nose.
    May not apply when the two masses are moving apart at the speed of light, though. In that case they may not exist for each other.
