Why does the Moon not fall into the Earth, but gets farther and farther away

The motion of a celestial body in space gives it a certain vibrational frequency, which determines its position in a certain orbit, not on the ground.

Why doesn't the Earth fall into the sun.

Why is the Moon moving farther and farther away from the Earth.

The Earth is moving away from the Sun for the same reason that the Moon is moving away from the Earth at a rate of about centimeters per year. The Moon is moving away from the Earth at a rate of about centimeters per year, and this is why, scientists have not yet figured out why. The theory of the Earth's distending holds that it is caused by the slow transformation of the Earth.

Scientists have observed that the Moon is moving away from Earth at a rate of about centimeters per year. In 100 years, the length of a day on the earth has increased by about one thousandth of a second to two thousandths of a second, that is, the slow second of one day in one year and one slow second in one year.

The theory of earth expansion holds that because the Earth-Moon system is a rotating body, the Earth's rotation is slow for one year, and the entire Earth-Moon system is slow for one year, and the half-longitude of the Earth-Moon system increases by centimeters. It's like a skater spins slower when his arms are flattened; The skater spins slower and the skater gets a larger body radius.

Because the Earth-Moon system is a rotating body, the Earth-Moon system should also obey the law of conservation of angular momentum.

Let the angular momentum of the Moon before it slow down as f = mvr , and since v = s t, then f = mrs t where s is the distance of the Moon in 365 days and t is 365 days.

So the angular momentum of the Moon before it slows down is f = m384401 km s 365 days (1).

So the angular momentum of the Moon after slowing down is f1 = m384401 km + cm s 365 days + seconds.

Because centimeters are 384401 kilometers over.

seconds is 365 times the day.

So the angular momentum of the Moon after slowing down is f1 = m384401 km + (384401 km days + 365 days).

So the angular momentum of the Moon after slowing down is f1 = m384401 km (1+ 365 days (1+ (2)).

Because 10000000001 and 100000001 pretty much the same.

Therefore, Eq. (2) is the same as Eq. (1), the angular momentum of the Moon is conserved, the angular momentum of the Moon does not change, and the theoretical calculation and practical measurement are completely consistent. This is enough to prove that the Moon is moving away from the Earth at a rate of about centimeters per year, which is a slowdown of the Earth by 05 seconds.

The planet is completely lostMoonIt would take at least 3 billion years, so we don't need to worry too much about that at all.

The Moon is the largest celestial body on Earth and the only one located in the habitable zone. But in the solar system.

There are only two celestial bodies that really have permanent residency, the Earth and the Moon. Both objects are massive objects that will continue to expand outward due to gravitational influence, eventually sucking the Earth away entirely. These two celestial bodies are the famous Moon, which is only one word different from the Earth or even less.

However, the Moon is the closest and farthest celestial body to the Earth, and the farthest distance from the Earth is only about 10 kilometers. The moon has also become the only natural satellite in space worthy of the name, and has become an indispensable and irreplaceable thing in human space exploration and technological research. <

The Moon continues to move away from Earth every year.

Because the Earth's attraction to the Moon is getting weaker, the Moon's detachment from the Earth is accelerating. During this process, the Moon moves away from the Earth about centimeters every year. Although this distance is very small, now about 3 billion years from now, the entire Earth will be completely out of control of the Moon, which means that we will not be able to see the Moon when we look up.

This time will reach 3 billion years.

The speed of measuring the shadows between the celestial bodies itself is very fast, but because the Moon itself is a planet of the Earth, and the Moon itself will rotate according to the Earth, the Moon does not detach from the Earth so quickly. In this case, it will take about 31 years for the Earth to completely lose the Moon. But before that, we humans may have been directly extinct due to various problems, so this issue itself is not within the scope of human discussion, after all, the time span between celestial bodies is too large.

Finally, the distance between the Moon and the Earth is shrinking, but the Moon is still the only natural satellite of the Earth, and once the Moon loses its influence on the Earth, then life on Earth will be greatly affected, and even cause the Earth's surface to be molten magma. Cover.

Although we don't see the moon every night because of the weather, the moon has been orbiting the Earth for 4.6 billion years since its inception, and a deep friendship has been forged between the two. However, some scholars have found that the Moon is silently moving away from the Earth, and it may be lost in hundreds of millions of years. <>

Let's go back to the earliest days of the Earth's formation, when the Earth rotated at a very fast rate of several times as fast as it does now. At that time, the moon may have been due to coincidence, or it may have been affected by the earth's gravity, which made it move tightly around the earth tens of thousands of kilometers away, invisibly like a brake inseparable from the earth. At that time, there was no liquid water on the surface of the earth, and there was a lot of friction between the two, but this did not affect the speed of the moon's rotation around the earth.

As early as the last century, Charles Darwin used formulas to try to measure the distance between the Earth and the Moon. It can also be seen that human beings have never stopped exploring the mysterious universe since ancient times. The reason why the Moon is getting farther and farther away from the Earth is mainly due to tidal phenomena.

Water resources are increasing, meteorite impacts are getting more and more serious, and with the change of the times, perhaps one day in the future, the attraction of the earth to the moon will become weaker and weaker, and so in the opposite direction, the distance between the two will naturally become farther and farther. Careful friends will find that in fact, the time of the day has become shorter and shorter, and the 24-hour calculation method is no longer suitable for the present, and this is the impact of the moon's distance. <>

So will the moon's distance have an impact on humans? There is no doubt about this, if the moon is lost, human beings not only lose the 24-hour change, the magnetic field of the moon has an important impact on the biological clock of human beings, maybe that day life on the earth will also disappear silently, at that time it will be a huge disaster for human beings.

The Earth may lose the Moon in 200 billion years, because the Moon is now significantly behind the Earth's rotational speed.

At the current rate of distant, it is possible that humanity will only need another 3 billion years or so, and when it looks up at night, it will no longer be able to see a bright moon!

For billions of years, the Moon has not known how many meteorites and small celestial bodies have blocked the impact of the Earth. The surface of the moon is full of craters, densely packed and too numerous to count.

Third, it is also possible that one of the moon's orbits is deviating from the earth year by year. The last one is the reason that the Earth's orbit is deviating from the Earth, and the Moon's orbit is a secret of nature or the universe, and the affected human beings cannot change such an orbit. When such a situation arises, human beings can only silently accept it, after all, each planet has an orbit, which is its established rule.

The offset of the running track, which cannot be compensated, cannot be changed. So when such a situation arises, people can only accept it slowly.

It's true, this has to do with the gravitational pull of the moon on the earth, and the gravitational pull of the moon on the earth creates a tidal force on the earth, causing the earth to slow down its self-transformation, so the moon slowly moves away from the earth.

It is true that the Moon is about 60 times the radius of the Earth, and because of the tidal reaction between the Moon and the Earth, the Moon is leaving the Earth at a rate of about 2 centimeters or more per year.

It's actually true. Due to the influence of the tides, the Moon will continue to absorb some of the Earth's energy every year, pushing itself farther and farther, at a speed of about 2 centimeters per year.

1. The rotation of the moon.

The Moon rotates while revolving around the Earth, and the period day is exactly a sidereal month, so we can't see the far side of the Moon.

This phenomenon is called "synchronous rotation", or "tide locking", and is almost a universal law in the world of solar system satellites. It is thought to be the result of the long-term tidal action of satellites on planets. The balance movement is a wonderful phenomenon that allows us to see 59% of the surface of the moon.

There are mainly the following reasons:

1. In different parts of the elliptical orbit, the rotation speed does not match the angular rotation velocity.

2. The intersection of the white and equator.

The Moon moves half a degree per hour relative to the background starry sky, i.e. it is similar to the apparent diameter of the Moon's surface. Unlike other satellites, the Moon's orbital plane is closer to the ecliptic plane than near the Earth's equatorial plane.

The time it takes for the Moon to orbit the Earth (one sidereal month) is called a sidereal month, relative to the background starry sky; Whereas the time it takes for a new moon to take for the next new moon (or between two phases of the same moon) is called a synodic month. The synodic moon is longer than the sidereal moon because the Earth itself travels some distance in its orbit around the Sun during its orbit.

2. The revolution of the Moon.

The Moon orbits the Earth in an elliptical orbit. The great circle of this orbital plane on the celestial sphere is called the "white path". The plane of the white channel does not coincide with the celestial equator, nor is it parallel to the plane of the ecliptic, and the spatial position is constantly changing.

Cycle day. The average inclination of the lunar orbit (white path) to the Earth's orbit (ecliptic) is 5°09. 、

Because its circular motion around the Earth cancels out the gravitational pull of the Earth.

Now that the Moon is slowly moving away from the Earth, why is it slowly moving away? Although the Earth has only such satellites, it can be said to win, because the Moon is the most unique of a known natural satellites, and the mass of the Moon and the Earth are in proportion to all other moons and their stars, from the proportions, for example, the Moon is the largest and even surpasses the mass of the satellite.

So how did such a huge moon form? In fact, there are many doubts about the formation of the moon, there are many different statements, one of the most widely accepted is that the moon came from the earth, but the time of formation is the beginning of formation. When the Earth was first formed, it was still a very high-temperature lava planet and the Moon was absent.

The Earth may not think that a large object similar to Mars was hit by itself. This imaginary celestial body has a name called Eiya. If you hit the Earth, then the story behind it probably doesn't exist.

Scientists believe that the angle of Eyyada's hit is very drilling, it is in close contact with the angle of inclination and the Earth, at this time, the Earth is still free of life, so there is no big deal, this effect has lost a part of the material that caused the Earth and Eyyada, it is bound by the Earth, it is surrounded by floating and running on the Earth, and these gravel and dust become the planetary rings of the Earth, just like the planetary rings of Saturn that we see now.

In these gravels and dust, there are some mass and large individual individuals. On Earth, the mass of the planetary rings will co-condense around the surrounding gravel and dust, gradually forming a small celestial body that has gone through hundreds of millions of years. This small celestial body gradually merged and cleared all the broken orbits.

Stone and dust, and finally, the moon is formed.

During the long years of the universe, the Earth and the Moon, the formation of an interdependent relationship, especially the presence of the Moon, is very important for the stability of the Earth's ecosystem. I'm sure many people have heard the term "back of the moon", why are there masculine and dorsal parts of spherical types and rotating celestial bodies? In fact, the front and back of the moon are relative to the earth, because the moon and the earth have reached the tidal lock, so the rotation of the moon is the same, so the earth is always only on one side of the earth, and about 41 of the left and right parts are always opposite the earth, and the earth is not visible, which is the back side of the moon.

Because the moon helps the earth withstand a lot of meteorite impacts, the mass is increasing, and the centrifugal force is getting bigger and bigger, so it will slowly move away.

Because the Moon is halfway between the Earth and the Sun, it is subject to two gravitational forces at the same time, so it shifts.

That's because there are some deviations in the movement of the Earth and the Moon, which is why this happens.

The moon is the only satellite of the earth, which is the product of the collision between the earth and other planets, and the moon has been orbiting the earth since ancient times, but the moon cannot be separated from the earth because of the attraction of the earth's gravity. But the Earth is 81 times more massive than the Moon, and according to the laws of gravity, the Moon should be attracted and fall into the Earth, so why is it getting farther and farther away?

The circumference of the Moon around the Earth is nothing more than the gravitational pull and action of the Earth. Gravity is well known, but what is the role of the force? The force acting is in the opposite direction to the velocity of the object.

In the same way, if an object moving to the right is subjected to a force to the left. The velocity of the object slows down as a result. If the Moon orbits the Earth at a constant speed, then it will neither accelerate nor slow down.

The acting force is perpendicular to the direction of the object's velocity. We call this force "sideways" force. If the object is only subjected to a vertical force, it will neither accelerate nor slow down, but will only change direction.

Therefore, if you want to exert a continuous vertical force, the direction of the force must constantly change to remain perpendicular to the direction in which the object is moving. If the Moon really moves in a perfect circle, then the gravitational pull will always be a "sideways" force. It is clear that the gravitational pull on the Moon is not perpendicular to the direction of velocity.

In this case, part of the gravitational force is in the same direction as the velocity, so the Moon moves faster. The other component of gravity is the vertical force, so the Moon will change the direction of movement. The velocity of the Moon increases as it moves closer to the Earth and vice versa, and it decreases as the Moon moves away from the Earth.

That is, the Moon has been counteracting the Earth's attraction to the Moon with its own speed.

So why is the Moon moving farther and farther away from the Earth since it cancels out the attraction? The main reason is the transfer of the angular momentum of rotation of the Earth to the angular momentum of the orbit of the Moon! The angular momentum of the Earth-Moon system is conserved, and the angular momentum of the Earth's rotation is transferred to the orbital angular momentum of the Moon through tidal action.

How fast does the Moon move away from the Earth? Because astronauts set up laser reflectors on the lunar surface during the Apollo moon landing, astronomers today are able to measure the distance between the Earth and the Moon with great precision and convenience. In 1994, Dickey et al. published an article in the journal Science that the current rate of the moon moving away from the Earth is centimeters per year.

If we assume that the speed at which the Moon moves away from the Earth is always at this value, then the distance between the Earth and the Moon will increase by about 38,200 kilometers over a billion years. The average distance between the Earth and the Moon today is about kilometers, so under this simple assumption, the distance between the Earth and the Moon 1 billion years ago was about 90% of today, but there are still kilometers. And due to the tidal action, the rotation of the earth gradually slows down, and the angular momentum of the earth's rotation is gradually transferred to the moon, and the moon slowly moves away from the earth after gaining angular momentum, and the current speed away from the earth is:

centimeter years. This is why the Moon will move farther and farther away from the Earth, and the consequence is that the Moon will be out of the Earth's gravitational zone, and at that time the Moon will enter the gravitational zone of the solar system, and it is speculated that it may become a planet. It is also possible to collide with other planets. Of course, this kind of thing is long-term.
