the force of gravity between 2 object varies directly with th mass of the 2 object and inversly as the square of the distance between them. Therefore, shorter the distance, higher is the gravitational force between them. In the case of a group of objects, consdering them to be of same mass, the object closest to the point will collapse faster into it.

This is called the n-body problem. There is no known analytic solution. A common type of numerical solution is iterative. For each object, calculate the gravitational force between it and each other object. Apply classical dynamics to calculate the change in motion due to the net force. Choose a small time increment and calculate a new position and velocity for each object, and start again. The smaller the time interval, the more accurate the result, but the more computation needed.
