Gravity
Gravity is one of the 4 fundamental forces of universe that knows just to attract other matter towards itself .

As per myth an apple fell ob Newton (story was false ). In reality he got the idea much before.  Newton is associated with gravity and just found the effect of it, but could not find the mechanism.

In late 20th century a new theory was found of gravitation.  As per which the quantum of gravitation ends at a small subatomic particle with 0 reat mass. This particle is known as graviton. The exchange of graviton is a hot reason or mechanism which bring gravitation gravity in existence

There is a big misconception that gravity is due to the curvature of space time fabric. The space time curvature is just responsible for the density and intensity of gravitation of a particle
e. g The curvature of space time of black hole is infinite the, this tells us the is infinite and gravitational intensity is infinite but gravitational force is not infinite

Hence gravitation is just exchange of graviton.  The new definition derived is
[Rate and amount of graviton exchane is directly proportional to gravitational force which follows an invers spuare law]
