In space, what happens to gravitational interaction?

In space, gravitational interaction does not disappear; instead, it still exists and behaves in specific ways based on the distance from massive bodies like planets and stars. While gravity is always present, its strength diminishes with distance according to the inverse square law. This principle states that as the distance from a mass increases, the gravitational force decreases proportionally to the square of that distance.

In the context of space, particularly when we are discussing areas far from massive celestial objects, the effect of gravity can indeed be perceived as weaker than on the surface of Earth. For instance, while an individual in a spacecraft may feel a sensation of weightlessness, this does not mean gravity has vanished; instead, they are in a state of free fall towards Earth, which creates the illusion of zero gravity. Thus, it is accurate to say that gravitational interaction is weaker in space compared to experiences on the Earth's surface, where gravity is felt intensely due to the planet's mass and proximity.

This understanding is essential in fields such as aerospace engineering and astrophysics, as it influences the design of spacecraft, the calculation of trajectories, and the comprehension of gravitational interactions between different celestial objects.
