Why does the earth rotate steadily? What's the motive?

Since the earth was formed 4.6 billion years ago, it has never stopped spinning. The reason why the earth can always rotate is essentially because of the conservation of angular momentum. When the earth was not formed at first, there was a rotating nebula in space. The nebula collapses under gravity, and most of the matter falls into the center, leading to the formation of the sun.

After the birth of the sun, the generated solar wind blows other nebulae into the surrounding space. These remaining nebulae continue to revolve around the sun and eventually collide with each other to produce the earth. Because of the conservation of angular momentum, the earth retains the angular momentum of the nebula that originally revolved around the sun, so the earth will not only revolve around the sun, but also rotate. There is no resistance in space, so the revolution and rotation of the earth can last until today and into the distant future.

There are several reasons why the earth can rotate stably: First, it is related to the solar magnetic field. The sun has a huge magnetic field, and the magnetic control range of the solar magnetic field is the space occupied by the solar system. There are magnetic coils with different distances in the coverage of the solar magnetic field, which naturally form planetary orbits with different distances in the solar system.

Because the sun will rotate randomly, it will jointly push the magnetic field and the magnetic coil to make circular motion, thus triggering all planetary celestial bodies and satellite materials in the solar system to make circular motion around the sun.

Second, it is related to the vacuum weightlessness of the solar system. The space of the earth in the solar system is a weightless physical phenomenon in a vacuum state for the whole earth material. Because the sun has the characteristics of random rotation, only under the circumferential traction of the solar magnetic field and the orbit of the magnetic coil will there be a regular and stable inertia phenomenon of circular revolution.

Third, the earth's rotation movement is related to the revolution movement. The process of the earth's revolution around the sun is not a linear motion phenomenon, but a micro-arc state. Therefore, the circular rotation of the earth produces an arc deflection force, which causes the included angle between the earth axis and the ecliptic plane to be about 23 degrees when the earth rotates. It is this angle phenomenon that makes the earth constantly appear angular dynamic physical phenomenon in the process of revolution, which will lead to the natural occurrence of the stable rotation of the earth.

I wonder if this answer is accurate? ! If the reader thinks what I said is reasonable after reading it, I hope to give you a compliment and pay attention to me. Welcome to join the discussion and study.

In addition, the existence of the moon has played a considerable role in stabilizing the tilt angle of the earth's rotation axis. If there were no moon, the inclination of the earth's axis would change constantly, instead of being stable at 23.4 degrees as it is now.
