What is Gravity ?

Gravity is a fundamental force of nature that governs the interactions between objects with mass or energy. It is the force that pulls objects with mass towards each other.

According to Einstein’s theory of general relativity, gravity is described as the curvature of spacetime caused by mass and energy. Massive objects such as planets, stars, and galaxies curve the fabric of spacetime around them, and this curvature dictates the paths that other objects with mass will follow. In essence, objects with mass “fall” towards each other along the curves of this spacetime curvature, which we perceive as the force of gravity.

The strength of the gravitational force between two objects depends on their masses and the distance between them. The larger the mass of the objects and the closer they are to each other, the stronger the gravitational force between them.

Gravity is responsible for many phenomena in the universe, including the orbits of planets around stars, the formation of galaxies, and the structure of the cosmos on the largest scales. It plays a crucial role in shaping the universe as we know it.
