F = (G x Mss1) x (G x Mss2) Where Mss1 and Mss2, at a fraction of M1 and M2, account for the total mass responsible for the gravitational force between them. We no longer require dark matter to fill in for the apparent missing mass. The dark matter problem is solved. This paper also covers the inverse square law on gravity, explains why gravitational force appears to follow the inverse square and explains mathematically why it doesn't follow the inverse square exactly, hence its absence from my formulas. This theory is classical in nature and so relies on the fact that gravity is a force and is a natural phenomenon where the cause of gravity isn't explained but rather is accepted as a property of mass. Because this theory of gravity is novel and is a standalone replacement theory, this paper seeks to cover everything including gravitational waves, gravitational shielding, general relativity and dark matter we've already touched upon in this introduction. Because of the nature and extent of this paper, it is written in 'text book' form.
