Before Answering Why Gravity Exists? First we need to know what is Gravity. Gravity is a force that attracts any physical body towards the centre of the earth, or towards any other physical body having mass.

Gravity gives weight to the physical objects. As we walk on the surface of the Earth, it pulls on us, and we pull back. But since the Earth is so much more massive than we are, the pull from us is not strong enough to move the Earth, while the pull from the Earth can make us fall flat on our faces.

Everyday we Experience gravitational pull have you ever questioned about where the gravity comes from?

We know from Isaac Newton and his law of gravitation that any two objects in the Universe exert a force of attraction on each other. This relationship is based on the mass of the two objects and the distance between them. The greater the mass of the two objects and the shorter the distance between them, the stronger the pull of the gravitational forces they exert on each other.

In view of Isaac Newton Gravity is just a Force but According to Einstein Gravity is not just a force it is more than that, proved with his theory of relativity Gravity is a curvature in the space-time continuum.

**Why Gravity Exists?**

It’s hard to say that why gravity Exists in Nature. There are four forces in nature (gravity, electromagnetic, strong, and weak). who knows why they exists but we can Explain what causes Gravity.

in 1900s “Einstein’s theory says gravity is a bending of space and time,”It is very difficult to understand this or visualize it, but this treatment of gravity, called General Relativity, makes very precise predictions about gravity both under normal circumstances and also in extreme cases when describing huge masses and incredible speeds close to that of the speed of light.”

### What is General Relativity

General relativity describe as gravity as a geometric property of space and time, or spacetime.

In particular, the curvature of spacetime is directly related to the energy and momentum of whatever matter and radiation are present.

The relation is specified by the Einstein field equations, a system of partial differential equations.
