What exactly is it that gives the Earth its gravitational pull?

Gravitational attraction of all matter, the attraction of attraction to each other, is related to the mass volume of the object. Objects that are too close together will produce a certain repulsive force.

Why does gravity arise, Newton discovered the problem of gravity, it was he who was smashed on the head by an apple while thinking about the problem. The question of gravity comes to mind.

But there is currently no explanation as to why gravity arises.

The generation of gravity is linked to the generation of mass, and mass is an effect produced by the change of space, which arises by the production of mass attached to gravity.

Matter itself has a gravitational force, and there is a theorem called gravitation.

<>1. The gravitational force of the earth comes from the gravitational force of the earth, and the gravitational force of objects on the surface of the earth is partly the gravitational force that we perceive, and partly acts as the centripetal force that rotates with the earth.

2. Gravity is one of the inherent essences of mass. Each object must be drawn to each other by another object. Although the nature of gravity has yet to be determined, its existence and role have long been recognized.

Objects that are close to the Earth, without exception, are attracted towards the center of the Earth's mass. For anything on the surface of the earth is insignificant compared to the mass of the earth's own orb.

In 1665, the famous physicist Isaac Newton discovered the law of universal gravitation. This proves that gravity and matter coexist, and where there is matter, there is gravity. It is not only the earth that has gravity, but all matter has gravity between them. So, why does the Earth have a gravitational pull?

From the perspective of the formation of the earth, the earth is under the action of gravity, through the attraction of material particles to each other, continuous condensation, accumulation and evolution, so from this point of view, the earth also originated by gravity.

From the perspective of the earth's own characteristics, the earth is a sphere with magnetic force, so the center of the earth will naturally produce a huge gravitational force, which firmly attracts all the materials on the earth.

From the point of view of the law of the earth's motion, in the process of the earth's rotation around the earth's axis and the sun's revolution, due to the interaction between the earth itself and the earth and the sun, the earth has a gravitational force, which can compete with the sun's gravitational force, so that the earth will not be attracted by the sun's strong gravitational attraction and "go the wrong way".

Gravitation also exists between matter that is considered matter and antimatter, and is universal everywhere except for a slight modification of Newton's theory of universal gravitation proposed by Einstein's theory of general relativity.
