Perhaps many people have heard of a device called a perpetual motion device, but it is confirmed that a perpetual motion generator cannot really exist.

If eternal force cannot exist, what principles does the earth use to support it? In other words, what force does it use to maintain its continuous rotation and revolution? I’ll explain it to you below.

In fact, some people have done statistical analysis and believe that the earth has a net weight. What is the net weight of the earth? It’s that kind of data: six trillion billion kilograms. Maybe that kind of data seems to everyone to be a huge number. So is this data appropriate? To be verified.

Speaking of the earth, it came into being 4.5 billion light years ago. When it was created, it rotated around the earth's axis and revolved around the sun. From a physical perspective, what does it rely on to maintain power, and how does it continue to rotate?

In physics, there is a basic law called the conservation of kinetic energy and mass. According to the first basic law of heat, we know that all power cannot violate the law of conservation of energy. Therefore, many people go to nature to find energy, so that this energy can be continuously output and help people do many things.

However, according to the second basic law of heat, the principle of entropy increase, temperature will not spontaneously change from a low temperature to a high temperature. Therefore, calorific value cannot completely convert the pass rate. Such basic laws apply to all substances in nature.

The same is true for the earth. The earth has been rotating and there is no outward power. So what kind of output power makes the earth rotate?

To trace the initial driving force for the creation of the earth

Many people have learned about the factors that created the earth. There is a theory called cosmic expansion. This term is similar to how 4.6 billion light years ago, the entire solar system was dark and chaotic. At this time, there was no sun and no stars that we are familiar with. It was just a cluster of star orbits, and this cluster of star orbits Even radon and helium were created after the expansion of the universe, and there are also some heavy elements.

In this cluster of star orbits, molecules continue to collide with each other to generate angular force. This angular force is the basic principle of angular momentum in physics. The angular force has a fund in a certain direction. Net value, rotation occurs through movement, and the law of conservation of energy of angular force is the same principle.

It is attractive at this time. Due to the effect of attraction, this cluster of star orbits continues to collapse, causing many molecules to continue to gather towards the center, and this star orbit slowly A star will be produced that obeys the conservation of angular momentum and mass and continues to accelerate and rotate.

Its radius of rotation is getting smaller and smaller, and its speed is getting faster and faster. After tens of thousands of years of time, the substances in the star orbit have collapsed to the center position. , continuous collapse, it is said that it will turn into a hydrogen nuclear fusion reaction, that is, it will become the sun.

After becoming the sun, other substances rotated again, forming an astrolabe. In this astrolabe, dust particles collided again, forming higher planets.

It took tens of thousands of years for the familiar planets to form, including our mother Earth. Based on the conservation of kinetic energy and mass, and based on the conservation of angular momentum, the initial astrolabe analysis continued to rotate. And this rotation is also due to the effect of attraction that rotates around the center, which is the sun.

While revolving, it will also continue to rotate due to the effect of attraction. In this universe, it is confirmed that it is a vacuum state, so the rotation of the earth may be due to the inertial force caused by the explosion, and it does not require too much angular momentum to carry out the rotation. There is no frictional resistance in a vacuum pump, but the Earth's rotation is confirmed to be getting slower and slower.

Everyone knows that when the earth was first transformed, it took 6 hours to rotate once. In the dinosaur world, the time to rotate once was 21 hours, and now it is 24 hours. Perhaps one day in the future the Earth's rotation will become longer.

In fact, in addition to the factors of conservation of angular momentum, this also has the effect of lunar tidal energy. The tidal energy generated by the moon and the earth also blocks the earth's rotational angular momentum. During this process, the earth's rotational momentum will be transferred to the moon through energy and mass conservation.

Could it be said that the sun is also rotating and revolving? The answer is no doubt.

The solar system is revolving around the solar system, and the rotation of the sun cannot be observed by human eyes, because the sun itself is composed of molecules, and the molecules in the sun are low-temperature In the case of plasma, since there is no fixed surface, the rotation period cannot be directly observed. However, after scientific research, the sun's rotation period is 27 days.

In the past, no one gave energy to the Earth's rotation and revolution. Its current rotation and revolution are the angular momentum inertial force generated from the expansion phase of the universe.
