What Is a Gravitational Force?

Gravitation (English: Gravitation, Gravity), the attraction between any two objects or two particles and its mass product, the most common force in nature, referred to as gravity

(One of the basic forces of nature)

The attractive force between any two objects or two particles that is related to the product of their mass is the most common force in nature, referred to as gravity. in

1) A law of interaction between objects, discovered by Newton in 1687. There is mutual attraction between any object.

In the early 17th century, people were able to distinguish many forces, such as

The reason why light is sucked in by black holes is because the gravitational force causes space distortion, and light enters black holes with the distorted space. Everyone knows that light only goes in a straight line. Light still walks in a straight line, but space twists into a black hole. For example, draw a line on paper and twist that piece of paper, it is still a line.

Light travels in a straight line. According to general relativity, space will bend under the action of gravitational field. At this time, although light still travels along the shortest distance between any two points, it is no longer a straight line but a curve. Visually speaking, it seems that light originally wanted to go straight, but its strong gravitational pull pulled it.
