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.

Without the Moon, life on Earth would probably not exist.
The Earth's magnetic field is most likely related to the gravitational pull of the Moon. Without the Moon, the Earth would most likely become a planet without a magnetic field, like Venus. And the significance of the earth's magnetic field to life is very important.
For example, the solar wind and cosmic radiation are intercepted by the Earth's magnetic field, without which life on Earth would not be able to survive.
The Moon acts like an umbrella to intercept many asteroids and meteorites that should have fallen to Earth. Without the Moon, the chances of the Earth being hit by interstellar matter would be greatly increased.
The biological rhythms of many plants and animals on Earth are influenced by the Moon, including humans. Without the Moon, biological rhythms would become chaotic, which in turn would have an impact on the genetic stability of organisms.
Tides, seasons, weather, etc., all of which will be different due to the disappearance of the moon, and it is likely that the earth will become completely different.
In other words, if the Moon leaves us, our Earth, although still Earth, will no longer be suitable for living things.
-
The greater the distance between the two, the weaker the moon's ability to block the impact of meteorites on the earth, and the more serious the tidal phenomenon on the earth.

Through a large number of observations, scientists have found that the time when the Moon has been away from the Earth may have started a long time ago, and the average distance from the Earth is about a centimeter per year. It's very, very small, but if it's long enough, one day, the moon will leave us. The Moon has gone from more than 100,000 kilometers from the Earth to 380,000 kilometers now.
Why does the Moon keep moving away from the Earth? In fact, the root cause behind it is that the mass of the moon is too large, and the mass is too large, and the gravitational effect between the earth and the moon will constantly seek a balance. Although the Moon revolves around the Earth, due to its very large mass, it also produces a greater repulsive force that keeps the Moon moving away from the Earth.
In fact, this situation is also very normal, knowing that a more massive object is reluctant to become a satellite of a planet unless the mass of the planet is much greater than that of the object. The mass of the satellites of other planets is more than 1,000 times the mass of the satellite, and this huge mass difference makes the satellites dare not have the slightest idea of escaping, and the difference in strength is too great.
However, the mass of the moon is only 81 times that of the earth, and this mass ratio is not a very big gap between celestial bodies, so it is very difficult for the earth to completely bind the moon, and the moon does not look down on the earth, and will not willingly keep revolving around the earth, and the earth is not large enough in the eyes of the moon. If the Earth is replaced by Jupiter, the Moon will naturally not have the slightest idea of escaping, because the difference in strength is too big and does not allow it.
The moon is a little bit away from the earth, and one day in the future it will leave the earth and become a free body, once the earth loses the moon, a huge catastrophe may come, what should human beings do at that time? Some people may think that human beings are also facing a huge catastrophe, and if they don't get it, they will end in a mass extinction like the dinosaurs 65 million years ago.
Is this really the case? In fact, everyone thought that it would take a long time for the Moon to completely break away from the Earth's gravity. As early as billions of years ago, the moon has been a little bit away from the earth, but it cannot completely break away from the earth, even if it leaves the earth one day in the future, at that time, human civilization may have already become a powerful interstellar civilization.
The power of science and technology is endless, and as long as human beings become a powerful interstellar civilization, is this problem of the moon still a problem? Of course not, even if the moon is no longer there, we can still rely on the spacecraft to pull a celestial body of the same mass to make up for the position of the moon, so that it can continue to form a stable gravitational balance with the earth and continue to stabilize the ecological structure of the earth.
This is the power of science and technology, as long as the power of science and technology is strong enough, there will be no disaster that can threaten the survival of the earth and mankind. It is possible that in the future, after human civilization is strong to a certain extent, we will transform the earth in all aspects to make it a planet that can wander. At that time, we will take the earth with us, leave the solar system, and wander and explore the vast universe.

It is understood that in recent years, some scientists and scientific and technological workers from all over the world have discovered that the moon is gradually moving away from us and will become darker and darker after in-depth observation and research.
Scientists in the United States and France used the mirror placed on the moon when the American astronauts landed on the moon in 1969 to measure the results show that the distance between the earth and the moon has increased by more than one meter in the past 28 years, and scientists in the United States and France use the accurate time measurement method to measure the change in the distance between the moon and the earth, this method is to project the laser pulse onto the mirror surface and then reflect it back to the ground, a round trip is about a second, and the change in the time taken to go back and forth is constantly measured, and the change in the distance between the moon and the earth can be known. Several measurements have shown that the distance between the Earth and the Moon increases by almost 4 centimeters per year due to the frictional action of the tides on the Earth's surface.
Scientists believe that under the action of the moon's gravity, the earth produces tides, and part of the energy in this tidal movement is dispersed into the earth's oceans, and due to the loss of this energy, the movement of the lunar system is affected, which is why the moon is gradually moving away from the earth.
Through the study of nautilus fossils, two American geographers also found that the moon is indeed moving away from the earth. The two scientists observed the study of several extant nautilus fossils, and found that the corrugated threads on their shells have the same performance as tree rings, and the threads are divided into many compartments, although the width is different, but there are about 30 small corrugated growth lines on each interval, which is exactly the same as the number of days in a month in the modern lunar calendar.
It was observed that the nautilus's wavy growth line grew one per day and one per month. Inspired by this particular growth phenomenon, the two scientists looked at the fossils of the ancient nautilus and were surprised to find that the number of growth lines per ancient nautilus gradually decreased with the age of the fossils. However, the growth line of snail shells of the same geological age is fixed.
Studies have shown that there are 30 suprashell growth lines in modern nautilus, 26 supra-shell growth lines in the Cenozoic Oligocene, 22 in the Cretaceous of the Mesozoic, 18 in the Jurassic, 15 in the Carboniferous of the Paleozoic, and 9 in the Ordovician. The two geographers calculated the distance between the moon and the earth at that time based on the law of gravitation and other physical principles, and the result was that more than 400 million years ago, the distance between the moon and the earth was only 43% of what it is now.
Scientists have also conducted a calculated study of lunar eclipses that have been recorded for nearly 3,000 years, and the results are in perfect agreement with the above reasoning, proving that the moon is gradually moving away from the Earth.

It's not whether it will be, but in reality.
According to the latest observations.
Now the Moon is moving away from the Earth at an average distance of a few centimeters per year. Of course, as we get farther and farther away from Earth. This speed will increase. But that's not what we're going to worry about. Hundreds of millions of years later.
That is, initially the Moon was very close to the Earth. Slowly, it's so far away. In the future, it will be farther and farther away.

In fact, the Moon is getting closer and closer to the Earth.

The moon revolves around the earth, is the only natural satellite of the earth, and has a close relationship with the earth, and the impact on the earth is very large, but the latest research shows that the earth has been moving away from the earth, what is going on? Then the following is byKnowledge of horoscopesLet's find out whyWhy the Moon is gradually moving away from the EarthThe Moon is indeed moving away from the Earth, at a rate of centimeters per year, a phenomenon that occurs mainly due to the periodic tidal action between the Earth and the Moon. The so-called tidal action, that is, starvation, because the moon has a gravitational attraction to the earth, resulting in the earth's seawater being attracted by the moon makes the seawater have a fluctuation phenomenon in the vertical direction, which will lose the energy of the earth's rotation, resulting in a decrease in the speed of the earth's rotation, resulting in the moon moving away from the earth.
Maybe many people don't understand why the earth's rotation speed decreases and the moon will move away, here we see the earth and the moon as a whole, the decrease in the earth's rotation speed is equivalent to a decrease in kinetic energy, and the energy remains unchanged in a system, then it will inevitably lead to an increase in the potential energy of the moon relative to the earth, so the distance between the earth and the moon will increase, and the moon will be far away from the earth. The speed at which the Moon is moving away from us can be accurately calculated, and Apollo once placed a rangefinder on the lunar surface, measuring that the distance between the Earth and the Moon increases by about 38 millimeters per year. Of course, the Moon does not always move away from the Earth at this rate, and will eventually slow down, and even get closer to the Earth at a certain distance, moving back and forth within a certain range.
Changes in the orbit of the moon can also affect the evolution of life on the earth in ancient times, because the moon has a huge mass in ancient times, the use of tides to lock the earth from a chaotic state to a stable orbit, so that the earth's surface environment is relatively stable and the climate change is not so drastic, which is conducive to the growth of primitive life. According to scientists' calculations, in about 20-3 billion years, the sun will become a red giant, the volume will expand, the temperature of the earth will gradually rise, until the sea water is completely evaporated, at this time there will be no tidal action, the speed of the moon away from the earth will also slow down, until the sun will submerge the earth, and the bond between the moon and the earth will come to an end.

According to scientists, the Moon is gradually moving away from the Earth.
Addendum: Was the moon man-made in prehistory?
1.The astronomical parameters of the Moon prove that it is not a natural celestial body.
Scientists have found that the Moon is an unusual celestial body, it is much larger than the moons of natural celestial bodies, the diameter of the Earth is 12,756 km, the diameter of the Moon is 3,467 km, which is 27% of the diameter of the Earth, the diameter of the Hidden Star is 6,787 km, the largest one is 23 km in diameter, it is Mars, Jupiter is 142,800 km in diameter, there are 13 moons, the largest one is 5,000 km in diameter with Yuchiri, it is Jupiter's, and Saturn is 120,000 km in diameter. There are 23 moons, the largest of which is 4,500 kilometers in diameter, which is the size of Saturn, and the moons of other planets are not more than 5% of the diameter of the parent star, and the moon is intended to reach 27%, which indicates that the moon is not an ordinary celestial body.
2.In the same way that scientists use lunar seismic waves to study the properties of the interior of the Moon, the Moon is a hollow sphere made of titanium (a high-purity metal on the Moon).
Human beings have always had a very high pursuit and praise for the moon, rotating around the earth while rotating, which brings moonlight to the earth, making the night no longer so dark, and its moonlight is always so bright and clean. Nowadays, people are also accustomed to the existence of the moon, but now with the continuous development of science, human exploration of the moon is getting deeper and deeper, and it is found through surveys that the moon seems to be moving away from the earth little by little, which also makes people feel worried, this seems to be breaking up with the earth, so if the moon continues to accelerate away from the earth, what will the earth become in the future? >>>More
The moon is solid, and whether it can retain the atmosphere depends on whether gravity can balance the entropy caused by the diffusion of microscopic particles of gas. This is related to the mass of the Moon, its volume, its surface temperature, and the composition of the atmosphere.
The most vulnerable part of the Earth's biosphere is the atmosphere. Scientists give an example of using a large globe to paint on the map, that layer of paint and the globe. >>>More
