Why is gravitational force attractive in nature & not repulsive?
The most basic question that wasn't answered by any textbook - why is the gravitational force attractive in nature and not repulsive? Tried thinking about it for some time and then found an answer that says because "F=GMm/R^" will always be 'positive'. But that's not very convincing to me. Does anyone know what is the origin of the gravitational force?
