PRIDE CHEKERAMoon orbiting a planet, Earth? Here we have another equation,
which is based on Newtonian universal gravitational law, which
states: for every two bodies of mass "m" and "M", there is a
force of attraction which is directly proportional to the product
of their masses and, as per the inverse square law, inversely
proportional to the distance between them. It presumes that,

this equation for the Moon to orbit the Sun, or all other planets
to orbit the Sun, and all other similar phenomena in the whole
universe. In this scenario, gravity was a permeating force of
attraction due to the mass of an object. But this theory had some
flaws when we consider motion involving more than two bodies,
this was not taken into account in this Newtonian mechanics.
And the notion of space and time here was regarded as an
absolute realm, and space and time were seen as separate
entities.
This turned to be a field of interest to Einstein, a genius who
modified Newtonian mechanics into a triumph which became
the backbone of modern physics, to engineering. He dwelled on
the limits of Newtonian physics, and through rigorous thinking
and gedanken experiments, calculations, and perpetual
consultations, he topped the physics society and made history
which is found in every book of physics. History is part of
another story, what matters much here is the brilliant theory
expounded by Einstein, which revolutionized cosmology,
