That’s the universal equation for the force of gravity. Basically, the greater the mass of two entities, and the smaller the distance, the more they are pulled towards each other.
Now, Let’s use this logic, and make a formula for love!
L = Love
T = Time for the feelings to develop
F = Force at which two people are pulled together
G = Subconscious base attraction constant
M1 = Amount by which person 2 needs someone like person 1.
M2 = Amount by which person 1 needs someone like person 2.
R = Fear keeping them apart
