It is a force of attraction that exists between two objects and deals with the standards of living, orders by which such objects are put in harmony in the universe.

It is defined as the force of attraction between any two masses and results are most often observed where at least one of the masses is a planet or a star.

Newton enunciated the law of universal gravitation in the 17th century as it applies to forces that gradually are inversely proportional with distance and directly proportional to product of two masses / objects.

Later on, Albert Einstein came up with this knowledge enhanced by his General Theory of Relativity where he formulated that gravity is not merely a force pull but a warping of spacetime due to the presence of mass.

Gravity is the force explanation for planets in orbit around a star, stars in orbit around galaxies, as well as galaxies in clusters. Gravity in earth provides weight to the physical objects and has an impact on the path of a thrown object.

It also shares its responsibilities in tides, pressures, time dilation and many more phenomena and thus shows how integrated it is into the fabric of the universe.
