Originally Answered: At what distance does Earth’s gravity end? Using Phu Dihn’s age of earth, 4.5 billion years, and the speed of gravity equalling the speed of light, earth’s gravity ends 4.5 billion light years away from earth. This is an upper bound on the distance extent of earth’s gravity.
Moreover, at what height Earth gravity is zero?
Gravity can never become zero except maybe at infinity. As we move away from the surface of the Earth the gravitational force becomes weaker but it will never become zero. The gravitational force is inversely proportional to r2.
Similarly, what if gravity stopped for 1 second?
When gravity disappears for 1 second the outwards force balanced by the gravity would be released causing a massive explosion. In other star systems with more immense stars and natural phenomena such as pulsars and and especially black holes the explosions and expansions would be greater.
