A brief account on Newton’s theory of gravity


I can say, 1685, in physics, is the year of drastic change, a
milestone which made history. A new era of physics begun, its
beauty was enhanced, and newly discovered things adorned the
cosmos we always wander how it came to be. Sir Isaac Newton
taught us about the force of gravity, which holds planets in
orbits, which is responsible for the formation of large structures
such as stars, galaxies and superclusters.


But, although Newton discovered this, he was not able to give
an enough description of how this force traverse in space and
impose effects on various objects. His theory had a limit, it was
not able to give a description of the fundamental topology of the
universe.


Newtonian second law will only be applied on two bodies
exerting gravitational forces of attraction on each other. Most, if
not all, of you had come across this equation of motion, F = ma,
which is taught at secondary school. This equation is simple as it
looks, and it implies that when an external force is applied, there
is always an acceleration of a body of mass m in the direction of
the force applied. For all phenomena involving uniform
acceleration this is the case. What about a body such as the
