A law of interaction between objects, discovered by Newton in 1687. Any object has a mutual attraction to each other, and the magnitude of this force is directly proportional to the mass of the individual objects and inversely proportional to the square of the distance between them.

The law of gravitation was first proposed by Newton in his book The Mathematical Principles of Natural Philosophy, published in 1687. Newton used the law of gravitation to explain not only the laws of planetary motion, but also pointed out that the moons of Jupiter and Saturn orbit the planets in the same way. He believed that the moon was subject to the gravitational pull of the sun in addition to the gravitational pull of the earth, thus explaining the two mean differences, business trips, etc., which had long been discovered in the movement of the moon. In addition, he explained the orbits of comets and the tidal phenomena on Earth. According to the law of gravitation, Neptune was successfully predicted and discovered. After the law of gravitation appeared, the study of the motion of celestial bodies was formally based on the theory of mechanics, thus creating celestial mechanics. To put it simply, the more massive something is, the greater the gravitational force, and the gravitational force generated by the mass of the earth is enough to grasp everything on the earth.

Any two particles are attracted to each other by a force in the direction of the concentric line. The magnitude of this gravitational force is directly proportional to the product of their masses and inversely proportional to the square of their distance, independent of the chemical nature or physical state of the two objects and the intermediary matter.

Gravitational force is considered one of the fundamental forces in the universe in classical physics, and is directly proportional to mass and inversely proportional to the square of distance. But in Einstein's theory, gravity is no longer a fundamental force, but only a manifestation of the bending of the structure of space-time. The reason for the bending of the structure of space-time is the enormous mass.

According to the theory of general relativity, space-time around the sun is affected by the huge mass of the sun, forming a space-time curvature, while the planets move according to their geodesics, which is equivalent to a uniform linear motion in an inertial frame.

Each particle in the universe attracts every other particle with one force. This force is directly proportional to the product of the masses of the individual particles and inversely proportional to the square of the distance between them.

Specifically, black holes are cosmic objects under extreme conditions. It has an extremely strong attraction, and when scientists explain this attraction, they attribute it to the curvature of space. And the reason for the curvature of space is the huge mass of the black hole itself.

Quantum mechanics believes that gravity is caused by two particles exchanging gravitons.

In the early days, people were able to distinguish between many forces, such as friction, gravity, air resistance, electricity, and manpower. For the first time, Newton accurately attributed these seemingly disparate forces to the concept of gravitation: an apple falls to the ground, a man has weight, the moon revolves around the earth, all of which are caused by the same cause.

The reason why light will be sucked into the black hole is because the gravitational force causes space distortion, and the light enters the black hole with the distorted space, everyone knows that light only walks in a straight line, and light is not sucked in by gravity, but light still walks in a straight line, but space distorts into a black hole, for example, draw a line on paper, twist that piece of paper, it is still a line.

Light travels in a straight line, and according to the general theory of relativity, space bends under the action of a gravitational field. At this time, although the light still travels along the shortest distance between any two points, it is no longer a straight line, but a curve. Figuratively speaking, it seems that light is supposed to go in a straight line, but the strong gravitational pull bends it.

Spiritual retreats believe that gravity is the interaction between matter. The gravitational field is the result of this action. And the result is like a spatial property. It is because of this nature of space that matter has inertia. And the magnitude of this inertia is only related to the mass of the substance. The magnitude of the mass, in turn, determines the magnitude of the gravitational force. This is the reason why gravitational mass and inertial mass are strictly proportional, and rightly so. Einstein was also right to establish the principle of equivalence in this way.

Inertia itself is not a force, it is a property of matter manifested in the gravitational field, don't make a fuss about gravity and inertial force, go to embarrass "Gravitational force is the source of inertia. ”

At different scales, different particle motions represent very different roles. This is also very philosophically reasonable.

In physics, gravitational waves refer to ripples in the bend of space-time, propagating outward from a radiation source in the form of waves, which transmit energy in the form of gravitational radiation. The general theory of relativity predicts the existence of gravitational waves. The existence of gravitational waves is a consequence of the Lorentz invariance of general relativity, as it introduces the concept of a limited propagation velocity that introduces interactions. Gravitational waves, by contrast, cannot exist in Newton's classical theory of gravity, which assumes that the interacting propagation of matter is infinite.

Gravitational attraction is considered to be an effect of the curvature of space-time. This bending is caused by the presence of mass. In general, the greater the mass contained in a given volume, the greater the resulting curvature of space-time at that volume boundary. When an object with mass moves in space-time, the change in curvature reflects the change in the position of the object. Under certain circumstances, an accelerating object is able to change this curvature and propagate outward at the speed of light in the form of a wave. This propagation phenomenon is called gravitational waves.

When a gravitational wave passes through an observer, the observer will find that space-time is distorted because of the strain effect. When gravitational waves pass through, the distance between objects increases and decreases rhythmically, and this frequency is the frequency of the gravitational waves. The intensity of this effect is inversely proportional to the distance between the sources that produce the gravitational waves. The orbiting binary neutron star system is predicted to be a very strong source of gravitational waves when they merge, due to the tremendous acceleration they generate when they orbit each other in close proximity to each other. Since they are usually very far away from these sources, the effect when observed on Earth is very small.

Gravitational waves should be able to penetrate places where electromagnetic waves cannot. So it is speculated that gravitational waves can provide observers on Earth with information about black holes and other exotic objects in the distant universe. These objects cannot be observed by traditional means, such as optical telescopes and radio telescopes, so gravitational-wave astronomy will give us new insights into how the universe works.

Gravitational force and gravitational waves drive the transformation of energy in the end times, and the source of energy is the huge energy source of the underground world in addition to natural energy.
