- It turns out that only NASA and RSA have records of lunar rocks, and other institutions have received them as gifts. The trust between human groups is not high, but after the return of the lunar landing probes of NASA, JAXA, ESA and ASA, everything changed. Return to peace.
Analysis of rock specimens brought back from the moon found that 99% of them are older than 90% of the oldest rocks on Earth. The age of the first rock that Neil Armstrong, the Apollo astronaut who landed on the moon, picked up after landing in the Sea of ??Tranquility was 3.6 billion years old. Some other rocks are 4.3 billion years old, 4.6 billion years old and 4.5 billion years old. It is almost as old as the Earth and the solar system itself, and the oldest rocks on Earth are 3.7 billion years old. In 1973, a lunar rock was determined to be 5.3 billion years old at the World Lunar Symposium.
What¡¯s even more puzzling is that these ancient rocks were collected from what scientists believe is the youngest region of the moon. But the rocks are still young compared to the surrounding soil. According to analysis, the lunar soil is at least 1 billion years older than the rocks. Scientists determined the chemical composition and found that the soil had nothing to do with rocks and seemed to come from elsewhere.
When an ASA spokesperson was asked about this, he joked, "Maybe alien spacecraft have come before, maybe it's some kind of space-time phenomenon. We are an engineering-based organization and are not good at theoretical physics."
As soon as this statement came out, the media went to top theoretical physicists to dig up the explanation of space and time. However, space and time are inherently complex topics because they involve the structure of the universe. There were a lot of people explaining, and most reporters with liberal arts backgrounds were dumbfounded. Even reporters who graduated with a major in theoretical physics had stars in their eyes.
The decay of isotopes can be accelerated in special environments. The potassium-argon dating method in rock dating has lagged behind the times. However, until a perfect space-time model is established, it is impossible to determine the true age of these rocks.
"Perhaps prehistoric humans or aliens used some kind of technology to accelerate the decay of isotopes. Potassium-40 will decay into calcium, which can be used as energy. This is a technology we can already use now." An astrophysicist said Explain it this way.
"Then why is the moon a little flat?" the reporter asked.
"It's still a mystery. Maybe God thought it was too round and flattened it." This sentence was originally a joke, but it was praised by creationists and made physicists very passive.
As early as the end of the 18th century, French mathematician Pierre-Simon Laplace noticed that the irregularly shaped moon "trembles" when it rotates.
"The mystery is that the moon is too flat," MIT scholars gave the answer. The moon is not a regular sphere, but a celestial body with a pole diameter slightly smaller than the moon's equatorial diameter. If we look closely at the shape of the moon, we will find that it looks like it has been "squeezed" by pinching the poles between thumb and index finger.
In the 1960s and 1970s, space probes discovered that the radius of the moon on the line connecting the moon and the earth's center is elongated. In other words, if the moon is divided into two halves along the equator, the cross-section will not be a perfect circle, but will look like a circle. An oval like a rugby ball, with the "tip" pointing toward the Earth. But no one has yet been able to give a completely convincing explanation for the cause of the moon's current shape.
One hypothesis is that the orbit radius of the celestial body is related to the rotation speed of the celestial body, so the 1:1 rotation-revolution period ratio can explain the current irregular shape of the moon.
Some scientists also hypothesize that the rotation-revolution period ratio of the moon in the early stages of its formation was 3 to 2, that is, it rotated 3 times in 2 revolutions. This situation lasted for hundreds of millions of years at most. Finally, the rotation slowed down due to tidal forces, and the rotation-revolution ratio Stable at the current 1:1. Calculations show that this period of faster rotation than revolution may have provided enough force to prepare the moon for its current shape.
There are still many mysteries, such as the mystery of escape and the mystery of the glassy surface of the moon. As for the fact that only one side of the moon always faces the earth, it can be explained by tidal locking. This phenomenon is common and is the case with Pluto and Charon.
Laplace¡¯s discovery of the irregular shape of the moon at the end of the 18th century was commendable, but what he did not see was that the moon was gradually moving away from the earth, about 3.8 centimeters away from the earth every year. This can be explained by the law of conservation of angular momentum, which is perfect. At least this answer can be used within the current system.
Apollo astronauts discovered that the moon's surface was covered with a glass-like material in many places, indicating that the moon's surface seemed to have been burned by a blazing fireball. As one scientist pointed out: The moon is covered with glass. Expert analysis has proven that this layer of glassy material was not produced by the impact of a huge meteorite. Some scientists believe that this is the result of the explosion of the sun or the result of frequent takeoffs and landings of spacecraft.
Among all mysteries, the mystery of lunar radioactivity and magnetic field are the most puzzling and sensitive.
It¡¯s an astonishing phenomenon that an 8-mile-thick layer of the moon is radioactive. When the Apollo 15 astronauts?When measured with a thermometer, they found that the temperature was surprisingly high, indicating that the heat flow near the Apennine Plain was indeed very hot. Some people speculate that the core of the moon must be hotter. What is puzzling is that the core temperature is not high. This heat is emitted by a large amount of radioactive materials on the moon's surface, but where do these radioactive materials (uranium, thallium and plutonium) come from?
As for the magnetic field, it is also one of the important arguments for the "Hollow Moon Theory" and the "Moon Spacecraft Theory". Earlier detection and research showed that the moon has almost no magnetic field, but analysis of lunar rocks has proven that it had a strong magnetic field. This phenomenon has puzzled scientists. If the moon once had a magnetic field, then it should have an iron core. However, reliable evidence shows that the moon cannot have such a core; and the moon cannot originate from other celestial bodies. (such as the Earth) gets a magnetic field, because if that were the case, it would have to be very close to the Earth, but then it would be torn apart by the Earth's gravity.
The density of rocks on the lunar surface is not much smaller than the average density of the entire moon. Therefore, it can be considered that the lunar core will not be composed of heavier elements such as iron and nickel. It may be plastic or partially molten. At a depth of 1,000 kilometers on the moon, the lunar mantle temperature will not be higher than 1,000¡ãC. According to the understanding of the internal conditions of the moon, the solid part of the spherical structure is not unique to the earth itself. The above-mentioned spherical structure of the moon is also the result of the differentiation of the entire lunar material sphere during the evolution of the moon.
These are all assumptions based on phenomena. Before a lunar base is actually established, no real evidence can be obtained and doubts can be quelled.
Last year, NASA sent a man to the moon. Although it almost made a joke, it successfully sent half of the samples to the ground laboratory and achieved some results. Afterwards, NASA showed the actual object, and the rumors finally almost disappeared.
Rumors that the Apollo moon landing was a hoax have been going on for a long time, but Li Zhuang belongs to the group of people who believe that the moon landing is real. The reason is simple. Even an authoritarian country like the former Soviet Union cannot silence hundreds of thousands of people, let alone the relatively free government of Citigroup.
¡°If no less than one person in a certain group of people knows the truth, it is only possible to keep the secret by excluding the others, and this is obviously not something that Citigroup can do. Only a madman could do this to attack a large number of elites in his own country for a scam.
During the Cold War, the relationship between the two superpowers was extremely tense. The aerospace technology of the former Soviet Union was also advanced. If NASA cheated, RSA would definitely expose NASA's lies and discredit Washington. Obviously, Moscow failed to do this.
Political struggles are very cruel, and conflicts between countries are even more intense. At that time, the Vietnam War was in full swing, and the two superpowers were fighting fiercely on the battlefield in Vietnam. The possibility of compromise with each other and jointly deceiving the world was zero. It may be difficult for modern people to understand that in the past, it was possible to fight for certain political ideas, but this situation did exist. Ubiquitous paranoia and brainwashing have continued for decades. Even the ruling class cannot avoid this kind of emotion. It is not simply material interests. , but a question of the direction of human society. To describe it in one sentence, feeling uncomfortable after eating is a direct manifestation of the rapid development of modern civilization and the failure of human social structure to adjust in time.
Of course, these things involve sociology and history, and are very complicated. They cannot be explained clearly in a few words, but at least they can prove that there is no possibility of compromise between the two major forces during the Cold War. This is a typical sociological and historical analysis and can be regarded as indirect evidence.
There is direct evidence. The Bathurst-class high-resolution lunar probe launched by NASA found things left behind by the Yankee Apollo program, including the wreckage of NASA's lunar module descent stage. The Katje-class large-scale lunar landing probe retrieved some lunar rock and soil samples. Currently, two of these rocks are on display at the National Museum of Australia and the Sunway Aerospace Science and Technology Museum, and the others are being studied by scientists.
Some media have questioned ASA¡¯s capabilities, believing that progress in the aerospace field will not be so fast, but ASA has never clarified. The rumors intensified, and even space agencies from other powers ridiculed ASA for cheating. Everyone has their own position and purpose when speaking. Asa has conducted large-scale exploration of the moon, but almost no results have been released. Many people feel uneasy because of this, although this is the habit of United Technologies Corporation.
"Why don't we explain it? To avoid the media's constant guessing, the Internet is now full of obscene language and insane political insults." Andreev mentioned this matter at a company party at the beginning of the year.
Li Zhuang shook his head and did not adopt the suggestion. Asa only did things and had no right to speak to the outside world. The spokesperson was also appointed by the public relations department of the headquarters. Computer experts have good reasons. "We are a private institution. Why should we prove to those idle people that our exploration spacecraft has landed on the moon? This is a waste of energy and money. They don't want to believe it."
There are several groups in Citigroup currently engaged in aerospace business.??Only NASA faces the public because its funding comes from financial allocations.
"Haha, Chen Deqi is not kidding me. He knows that I can't understand, but he insists on listing a bunch of numbers and formulas to see what else is underneath." The computer expert came back to his senses, shook his head, and decided to Finished reading this heavenly book.
"Actually, there is nothing mysterious about the moon. The only thing I am sure of is that aliens or our ancestors must have stayed there, and we are their genetic descendants, not creations, otherwise we cannot explain so many coincidences. I dare It is concluded that Li Zhuang will be furious after reading this article, and he will keep scratching his head while reading it."
"While Li Zhuang was vomiting blood, this guy Chen Deqi came to the rescue at the end, which really made people collapse. He really wrote this specifically to make fun of himself.
There are not many other files that can be seen. They are all written by professionals, including the research and development records written by Guobao and the report Zhou Qisen submitted to the management joint meeting during the adjustment process of Wesson Technology. However, Li Zhuang has not read it. Tian stared at the already huge Artificial Intelligence Research Institute.
"How about taking a look at what Zhou Qisen wrote? This adjustment is dazzling. I don't even know what they are thinking about." The computer expert scratched his head and admired this guy's super management ability.
(A lot of the text in this chapter comes from the Internet. Lao Lang would like to thank the author of the original version and hope they don¡¯t mind plagiarism in explanation.
A brief assessment of the Apollo program:
The Apollo program cost 24.5 billion U.S. dollars. This number is not large from today's perspective, but its gold content can be calculated based on purchasing power. The structure of the Volkswagen Beetle has changed little from the 1960s to the present. From 1960 to 1970, its average selling price in the United States was less than $800. It was relatively simple at the time, but even with the necessary configurations, it would not exceed too much. Now it starts from 18,000 U.S. dollars, which shows that the actual purchasing power of the U.S. dollar has dropped by at least twenty times. During the Cold War, everyone worked hard, but now there are many lazy people in Citigroup, and GDP cannot reflect the value created in special times, such as during the war.
Based on today¡¯s purchasing power, including the political efforts of participating scientists and engineers, the total cost of the Apollo program is estimated to be between 600 and 700 billion U.S. dollars in 2010 standards, while NASA¡¯s 2011 funding was approximately 19 billion U.S. dollars. In comparison, this plan can be called a waste of money. In addition to political points, its results include some lunar soil and rock samples, and the promotion of related industries, which is to send some astronauts to travel to the moon.
Even with today's technological level, it is almost impossible for NASA to build a permanent lunar base with a large refining plant with a little money, and it will only be a small base at most. These are rough estimates. Some people used the power generation to calculate that the money was only worth 289.4 billion yuan. Lao Lang felt that the actual situation at the time was not taken into account. Apollo¡¯s main control computer could not even match the performance of our PCs, but we The rocket engine may not be able to catch up with the thrust of the F1 rocket engine in another twenty years. The technology of high-thrust liquid oxygen kerosene engine and hydrogen oxygen engine was developed by Lao Maozi in the 1960s and 1970s. At that time, the two superpowers were crazy. Since the Cold War, From today's perspective, it's a cold joke, but it really brings out people's potential.
The development of science and technology is uneven and cannot be simply compared. Some areas have not made much progress. Atomic bombs were built before humans used computers. In the early 20th century, large fleets of powerful countries were fighting on the oceans. Today, the scientific and technological capabilities of all major countries are far superior to those of the past, but not every country has the ability to build them. At that time, the U.S. and Japan had naval fleets and nuclear weapons.
Book friends, just take a look, there is no need to take it seriously, Lao Lang just calculated it casually and has no intention of getting to the bottom of it, so please just laugh it off. )
