Why does the Earth revolve around the Sun? Why does the Earth revolve around the Sun?

The main thing is the effect of gravity, the sun is much larger than the earth, the sun attracts the earth, and the earth constantly revolves around the sun.

Because the mass and volume of the sun are much larger than those of the earth, it is mainly affected by the gravitational force and the spatial operation of celestial bodies, which causes the earth to revolve around the sun.

The mass of the sun is large, and the gravitational force is mutual from the perspective of classical mechanics, but the centripetal acceleration of the earth is much greater than that of the sun, so the earth revolves around the sun. If the Earth is about the same mass as the Sun, far enough away, then it will go around the center.

The fact that the Earth is not the center of the universe, but orbits an ordinary member of countless stars, cannot be changed by the subjective will of human beings. Why, then, does the earth revolve around the sun? You might answer without thinking – because the Earth is affected by the gravitational pull of the Sun.

It is true that the Earth revolves around the Sun because of the gravitational pull. However, two of history's most famous gods of science, Newton and Einstein, had different views on gravity.

One of Newton's greatest achievements was the law of gravitation, and he believed that there was a force of mutual attraction between all things, which he named gravitation. That is, the Earth revolves around the Sun because there is a mutual attraction between the two. But how does this mysterious force pull two objects that are empty in between?

Even Newton himself failed to figure it out. However, Newton's formula for gravitational attraction is widely accepted because it can accurately describe most phenomena within a certain range, and it is still very practical even now.

With the deepening of human understanding of the world, the inadequacy of Newton's law of gravitation has gradually been exposed. After Newton's theories dominated physics for more than two hundred years, Einstein came out and revised them.

Einstein's general theory of relativity creatively proposed that time and space are intertwined wholes, which together constitute a four-dimensional space-time, and space-time can be bent by objects with mass, and the so-called gravitational force is actually a manifestation of space-time bending. This astonishing view has completely subverted the human view of the universe. At the same time, the equations of general relativity give a more precise description of the universe.

In Einstein's theoretical framework, the reason why the Earth revolves around the Sun is because the Sun distorts the surrounding space-time. In this distorted space-time, the trajectory of the Earth is also distorted.

In the future, there may be a better understanding of gravity. Why does the Earth revolve around the Sun? There will be a deeper meaning.

Because, the sun is attractive to the earth. In fact, there is an attraction between any object, but because the mass of the sun and the earth is relatively large, the attraction is very strong, and the galaxies in the solar system are attracted by the sun, so the planets in the solar system will revolve around the sun, thank you for adopting.

The motion is relative, the reference object is different, the relative motion is also different, if the earth is selected as the reference, it can also be said that the sun revolves around the earth. Due to the influence of gravitation, the earth will revolve around the earth in a certain orbit.

Using the Earth as a reference, the Sun revolves around the Earth.

Because angular momentum is conserved. In fact, whether it is the earth or the solar system, nebulae, galaxies, etc., almost all of them are autobiographical, editions.

This may be traced back to the cosmic power**, the energy of the great ** makes the matter have angular momentum in the early stage, that is, the autobiographical phenomenon, before the formation of the earth, the solar system was originally a nebula, and the interstellar matter slowly accumulated, due to the conservation of angular momentum, the autobiography of the earth, the rotation of the sun and the planets, and the rotation of the entire solar system The angular momentum generated by the rotation of the entire solar system should have a conservation relationship with the angular momentum of the overall nebula before the original formation of the solar system. The sum of the angular momentum of the initial formation of the earth's material is also equal to the sum of the angular momentum of the earth's material now. For the Earth not to rotate, i.e. the angular momentum is equal to 0, it would be a very special state, almost impossible.

The reason why the earth revolves around the sun:

The Lord is the result of the gravitational force acting on the Sun and the Earth, and the gravitational force happens to be the centripetal force of the Earth's circular motion around the Sun. In the early stage of the formation of the solar system, more planets and asteroids and smaller interstellar matter may be formed, and in the early stage of formation, their initial state may be different from the planets in the current solar system, some may directly collide with other planets, or be captured by the planets, some may even fly away from the solar system and become interstellar matter, and some may be adjusted little by little, survive, and become independent individuals. This is the sun and other planets in the solar system now, and now they are in a relatively stable state. It's the result of selection and adjustment. 0

In fact, strictly speaking, the Earth does not revolve around the Sun, but around the center of the mass of the system formed by the Earth and the Sun (if the capacitive influence of other celestial bodies is not taken into account).This is because the effect of gravity is concentrated in this point, which means that the earth seems to be attracted to this one point. After studying high school physics, I know that in this case, as long as the initial velocity is not towards this center of mass (the earth is obviously not moving towards this center, the lucky one) will make a uniform circular or elliptical motion, in fact, the real circular motion does not exist, because there is resistance, its speed will continue to decrease, of course, this decrease is very small on the earth, otherwise we would have been baked.

Since the mass of the Sun is much greater than that of the Earth, the center of mass mentioned above can almost be considered to be in the center of the Sun. So there's nothing wrong with the Earth revolving around the sun.

The Earth does not revolve around the Sun.

The closest point of the Earth's distance from the Sun is recognized as 147 million kilometers, and the farthest point is 152 million kilometers. If the Earth orbits the Sun, the total length of the Earth's annual orbit is at least 923.63 million kilometers.

Based on the above data, the Earth's speed of revolution around the Sun is calculated to be more than 105437 km/h. The speed of movement somewhere on the surface of the earth when the earth rotates is about 1670 kmh, and the speed of movement of the earth around the sun is more than 63 times the speed of movement somewhere on the surface when the earth rotates.

It is paradoxical and completely untenable for the Earth to have to rotate in a regular, almost circular shape and to move left and right (or up and down) at a moving velocity greater than 63 times the speed of the surface rotation.

When an object rotates regularly, it hardly moves from side to side or up and down. If an object moves left and right or up and down and then rotates at the same time, its trajectory must be in a spiral, and the spiral shape is determined by the velocity ratio between the two.

If the speed at which the object is rotating is much greater than when it moves up and down or from side to side, the spiral is almost in a circular shape, and if the object is moving up and down or moving from side to side at a speed much greater than the speed at which the object is rotating, the spiral is almost in a straight line. If the speed of rotation of an object is equal to its speed of movement up and down or side-to-side, the distance traveled is equal to the circumference of the object (this state is now assumed to be a standard helix). And the larger the number of circumferences of the object, the more obvious this phenomenon appears.

The circumference of the earth is about 40,000 kilometers, and it is not doubtful that the earth revolves around the sun for one year, but to achieve the standard spiral state, then the migration speed of a point on the surface of the earth must reach 63 times that of the current one, in other words, to achieve the standard spiral state, the earth must complete one rotation in at least 23 minutes. Moreover, the trajectory of the Earth's rotation is almost equal to that of a ring shape.

The trajectory of the earth's rotation is 365 days, that is to say, the earth's rotation is 365 weeks and then repeats the original trajectory, according to this calculation, the speed of the earth's rotation or about one revolution or up and down is about kilometers per hour, and the daily migration distance is within 110 kilometers.
