nobleman Edmund Halley. Newton's universal gravitational
constant states that: every particle of matter in the universe
attracts every other particle with a force whose direction is that
of the line joining the two, and whose magnitude is directly
proportional to the product of the masses, and inversely
proportional to the square of the distance between them:


퐹푔= 퐺푚푟 20 푚


퐺푚 0 푚 is a constant since the masses of the objects are
constants, thus the following in simple proportional terms is:


퐹푔 ∝푟^12


As the distance between the two bodies in an orbital system
increases, the strength of the gravitational force decreases. Since
gravitational force is experienced in a gravitational field
‘concentrated’ with gravitational field lines, the further we go
from the center of a body the more gravitational field lines
diverge from each other diminishing the gravitational flux
density. This law was initially the basis for our understanding of
planetary kinematics until 1915 when Einstein discovered
something mindboggling. 1915 was a revolutionary year,
extension of Newtonian mechanics into a simplified description
of gravity and how it works. It became our basis of searching for
a quantum gravity theory.
