Maya civilization, which is widely concerned by the world, is a wonderful flower in the history of world civilization. Maya civilization, named after Indian Maya, is a great civilization independently created by American Indian Maya in isolation from ancient civilizations in Asia, Africa and Europe. Its websites are mainly distributed in Mexico, Guatemala and Honduras. Maya civilization was born in 10 century BC, which can be divided into three periods: pre-classical period, classical period and post-classical period. Among them, Mayan civilization reached its peak in the 3rd to 9th century, and was acquired by human beings before Columbus discovered America. Great contributions have been made in science, agriculture, culture, art and many other aspects. Comparatively speaking, the Aztec civilization and the Inca civilization, the other two civilizations born in this land of vast expanse in the Western Hemisphere, are not the same as the Mayan civilization. However, what puzzles people all over the world is that, as the only ancient civilization in the world that was born in the tropical jungle instead of the river basin, Maya civilization, like its miraculous rise and development, is full of mystery. Around the 8th century, the Mayans abandoned the highly developed civilization and migrated on a large scale. Every central city they created also terminated new buildings, the cities were completely abandoned, and the prosperous big cities became barren and swallowed up by tropical jungles. Maya civilization disappeared in the tropical jungle of America overnight. By the end of 1 1 century, although it was partially revived, compared with its heyday, its glory was not what it used to be. With the arrival of the bloody overseas expansion of capitalism, Mayan civilization was finally completely destroyed by Spanish colonists, and then lost in the tropical jungle for a long time. /kloc-in the 1930s of 0/8, john stephens, an American, first discovered the ruins of ancient Mayan civilization in the tropical jungle of Honduras. Since then, archaeologists all over the world have discovered many abandoned Mayan ruins in the jungles and wasteland of Central America. Without metal tools and means of transportation, the Mayans only relied on the primitive production tools of the Neolithic Age to create a splendid civilization.

Generally speaking, Central American civilization can be divided into three periods, the period from 1500 BC to 300 BC is called pre-classical period or formation period, the period from 300 BC to 900 AD is classical period, and the period from 900 AD to16th century is post-classical period. It is said that the Mayans began to build religious buildings 3000 years ago, and the earliest remains were composed of some simple earth graves. Later, it further evolved into the early Mayan civilization in the pyramid. It seems that the Mayan civilization was influenced by the earlier Olmec civilization, and the Mayan culture flourished between 200 BC and 800 AD. The Mayans developed hundreds of cities, of which Karti was the largest. Scholars estimate that at the peak, the city has 654.38+10,000 to 200,000 residents. Hundreds of cities have developed into many city-states with intensive agriculture and concentrated cities. Among them, the most striking remains are the pyramids built in the religious center and the palaces accompanying them. Other important relics include carved stone tablets written in hieroglyphics, which mainly describe genealogy, war victories and other achievements. The Mayans also participated in the long-distance trade in ancient Central America. The main commodities are cocoa, salt and obsidian. Since the 9th century, the city-states of classical Mayan civilization suddenly declined at the same time, which is still a mystery. In the 10 century, the once prosperous Mayan cities were abandoned in the jungle. Since then, under the leadership of Chen Chi Itza, some Mayan city-states have sprung up in the northern Yucatan Peninsula, and the post-classical period known as Mayan civilization in history began. In A.D. 1224, the city-state regime in Itza, Chen Chi was overthrown, followed by the city-state alliance headed by Mayapan. 1450 Maya Pan Zhengquan collapsed due to civil strife. When the Spanish landed on the American continent, the Maya region was in a state of disintegration. Contrary to the legend, there are still 3 million Mayans living in the "Maya that never dies" in Yucatan Peninsula, and many people still speak Mayan today.

Maya civilization is ancient and mysterious, but there are always some well-documented features. The following are some characteristics of Mayan civilization: 1. Mayan civilization belongs to the stone civilization, and the Mayans did not invent bronze ware, let alone iron ware. Ruins of Mayan civilization II. Master high-level construction technology. The Mayans could not use copper and iron, nor could they use wheelbarrows. Although the concept of wheel appears in pottery and a small toy, it is not practical in real life, but it has created a high degree of urban civilization. Agriculture takes corn as its staple food, so it is also called "corn civilization". There are no cows, horses, pigs or sheep, and there are no traces of animal husbandry. Farmers use very primitive Milpa farming methods. Mathematics adopts decimal system. They discovered and applied the concept of "zero" and mastered a high degree of knowledge of mathematics and astronomical calendar. No one will think it is great from the Arabic numerals in primary schools! Just 1, 2, 3, 4, 5, 6, 7, 8, 9, 0. Maybe you don't know, the concept of 0 was brought to Europe by Arabs from India. In ancient times, Europeans did not have such a simple concept of numbers. Greeks are good at inventing, but they must write numbers in letters; Although the Romans could use numbers, they could only use four numbers to represent them. Maya used a point, a horizontal line and a shell symbol representing zero to represent numbers. When archaeologists study the Maya digital system, they find that their digital expression is similar to an abacus. They use three symbols: a point, a horizontal line and a shell symbol representing zero-it can represent any number. A similar principle applies to the "binary" of today's computers. This counting method can be used for astronomical figures. In the carved stone pillars found in Girigua, Guatemala, figures of 90 million years and 400 million years were recorded. The Mayan calendar is very complicated, including the Jin Zhuo calendar with a period of 260 days, the lunar calendar with a period of 6 months, the lunar calendars with a period of 29 and 30 days, and the solar calendar with a period of 365 days. , and different calendars in different periods. According to modern astronomical observation, we know that a year is 365.2422 days, while the year measured by Maya is 365.2420 days. Maya calculated the famous Venus formula: Moon 20x 13=260 260x2x73=37960 Sun 8x13 =104/04x5x73 = 37960 mysterious symbol.

Venus 5x 13=65 65x8x73=37960 These formulas mean that each cycle will meet in a straight line after 37960 days, and according to Mayan myths and legends, the "gods" will then go to a quiet resting place. Venus calendar year refers to the time required for Venus to orbit the sun once. The Mayans spent 384 years observing and calculated 584 calendar years of Venus (they found that Venus just walked five times in eight earth years, and then repeated the cycle, so they divided the days of eight earth years by 5-2920-to get 584 days), but today's calculation is 583.92 days, and the daily error rate is less than 65438+. It is incredible to calculate the history of Venus with such high accuracy. Why do you want to develop such a large quantity? This number unit is so large that even modern people don't need it. From today's scientific point of view, such a large number may only be used in one discipline, that is astronomy. Astronomers often use a large number unit to represent the distance between galaxies, and only astronomical numbers can be so large. The Mayans in the calendar predicted that in the Mayan calendar, there was a calendar called "Golden Zhuo Calendar", which was calculated by 260 days a year, but strangely, there were no planets suitable for this calendar in the solar system. According to this calendar, the approximate position of this planet should be between Venus and the Earth. This symbol in Zhuojinli expresses the galactic core described by Maya, which is very similar to the well-known Tai Chi Yin-Yang diagram. Some Mayan scholars believe that this calendar named Zhuo Jinli records the operation law of the "four seasons of the Milky Way", and according to Zhuo Jinli, our earth is now in the so-called "fifth solar age", that is, the last solar age. During this period of the galactic season, our solar system is experiencing a "great cycle" that lasted for more than 5 100 years. The time was from 3 1 13 BC to 20 12 AD. In this "great cycle", the moving earth and solar system are passing a galactic ray from the core of the Milky Way. The cross-sectional diameter of this ray is 5 125 earth year. In other words, it takes 5 125 years for the earth to pass through this ray. The Mayans divided this "great cycle" into 13 stages, and the evolution of each stage was recorded in great detail. In the 13 stage, each stage is divided into 20 evolutionary stages. Each period lasts about 20 years. This calendar cycle is very similar to China's "heavenly stems" and "earthly branches", and the calendar is endless, not as endless as a straight line in the year of AD. They believe that since the creation of the world, the earth has passed four solar periods. When the stars in the solar system go through a "big cycle" under the action of this galactic ray, fundamental changes will take place, which the Mayans call "galactic assimilation". Judging from the time of the "great cycle" predicted by Maya, today is drawing to a close. During the 20 years from 1992 to 20 12, our earth entered the last stage of the "Great Cycle". The Mayans believed that this was a very important period before "assimilating the Milky Way". They call it the "earth renewal period". During this period, the earth should be completely purified. After the "earth renewal period", the earth will step out of the galactic ray and enter a new stage of "assimilating the Milky Way". Since the Mayan calendar is so accurate, their predictions should also have some basis. Today, with serious environmental pollution and continuous natural and man-made disasters, we can think about the enlightenment of Mayan prophecy.

Since john stephens, an American, first discovered the ruins of ancient Mayan civilization in the tropical jungle of Honduras in 1839, archaeologists from all over the world have discovered more than 170 abandoned ruins of ancient Mayan cities in the jungles and wasteland of China and the United States from BC 1000 to the 8th century. The footprint of Mayan civilization starts from Yucatan Peninsula in Mexico in the north and reaches Guatemala, Honduras and Honduras in the south. This mysterious nation has built a surprisingly huge building in the tropical jungle of South America. When the computer-generated images of the magnificent Tikal city appeared in front of people, many designers of modern cities lamented that the surface of the hall of palenque Palace, which was built in the 7th century, was 100 meter long and 80 meters wide. The Governor's Mansion in Uxmar consists of 22,500 stone carvings, which are carefully designed. Although the roof of Chyi Chin Itza's samurai temple has disappeared, the towering 1000 stone pillars still remind people of the spirit of that year. All this makes people feel that this is an extraordinary nation. With the further investigation of Mayan culture, people are surprised to find that the Mayans thousands of years ago had unparalleled mathematical attainments and unique enigmatic characters. Moreover, the giant buildings in chichen itza, Tikal, palenque and other places did not come from the needs of Maya's real life, but were built in strict accordance with the magical Mayan calendar cycle.

Edit this amazing knowledge

How accurate is the Mayan calendar and astronomical knowledge? They divided the year into 18 months, and the earth year they calculated was 365.2420 days. Compared with the 365.2422 days calculated by modern people, the error was only 0.0002 days, which means that the error was only one day around 5000 years. They calculated that the year of Venus is 584 days, which is only 7 seconds short of the 50 years of modern people. What an incredible number this is! How did the Mayans thousands of years ago have such an accurate calculation? They still maintain a special religious chronology. A year is divided into 13 months, and each month has 20 days. This is the so-called "Golden Zhuo Year". Where this calendar came from is really puzzling. Because this chronology is not based on the movement of any celestial body observed on the earth. Some people think that the calendar of "Zhuojin Year" was made by the ancestors of Maya on the basis of another planet we don't know yet. The Mayans mastered the concept of "0" at least in the 4th century BC, 800 years before China and Europeans, to 1000. They also created a 20-digit counting method, and their numerical calculus can be used in 4 million years. Such a huge astronomical figure can only be used for modern interstellar travel and measuring the distance between stars. Thousands of years ago, the Mayans slash and burn, covered their bodies with leaves and exchanged things with cocoa beans as the medium. Do they need such numerical calculations? The Mayan calendar can last 400 million years, and the difference between the solar year and the Venus year he calculated can be accurate to four decimal places. They have their own characters, which are hieroglyphics composed of 800 symbols and figures, and their vocabulary is as high as 30 thousand. They have exquisite carving, painting and bronze art (the preface says that the Mayans had no metal tools, so why is it called bronze art? )。 However, before the peak of this high civilization was born, the Mayans lived in tree holes for gathering. How did such a primitive tribe suddenly produce such a high civilization? Even in the16th century, the Indians seen by the Spanish on the Yucatan Peninsula full of historical sites still lived in mud houses with leaves and made a living by gathering and hunting. Obviously, the precise astronomical calendar and mathematics, the civilization and art admired all over the world, far exceed the actual needs of the almost primitive life of the local indigenous people in India. This makes anyone have to be deeply puzzled: how did the ancient Maya get that profound knowledge? How did the splendid Mayan culture come into being and then disappear? Maya slate

1On June 5th, 952, a stone tablet engraved with numbers and patterns was excavated from the ruins of a temple in palenque, an ancient Mayan city on the Mexican plateau. At that time, people only regarded this as a sculpture of ancient Mayan mythology. But in the 1960s, after people went into space by spaceship, American scientists who participated in space research suddenly realized that what was carved on the slate of palenque was a picture of an astronaut driving a spaceship! Although it has undergone patterned deformation, the air inlet, exhaust pipe, joystick, pedal, rudder, antenna, hose and various instruments of the spacecraft are still clearly visible. When this photo was sent to the American Space Center, the space experts were amazed and agreed that it was an ancient spaceship. It seems unbelievable, but it is a certain fact. Therefore, some scholars have put forward a bold view: they think that in distant ancient times, a group of intelligent aliens with high civilization may have appeared in the tropical jungle of America. They walked out of the spaceship, taught all kinds of advanced knowledge to the Maya in primitive times, and then drifted away. They were regarded as gods by the Mayans. The profound knowledge that is difficult to understand in Mayan culture was taught by aliens. The carving on the slate in palenque is also a copy of the alien astronauts by the Mayans. When the aliens left, they promised the Mayans to return to the earth, but they didn't come back in the days when the Mayans chased them and the priests predicted the return of the gods. Therefore, this led to the loss of the Maya's confidence in their religion and priestly rule, which led to the collapse of the entire national psychology, and finally made people leave their hometowns one after another and separate. Maya culture just disappeared. Perhaps people will accuse this view of being too hypothetical. But even if we deny this statement, we still can't fully explain the mysterious connotation of Mayan culture, many incredible miracles and the reasons for its sudden disappearance.

Edit this passage about Maya clothing and fashion.

Maya thought eye contact and long head were fashionable, so people would wrap cloth around the baby's head to deform it and hang beads on the baby's nose to change the muscle structure of the eyes. Maya dress is usually simple and can adapt to warm weather. Men wear loincloth, and women wear loose clothes, like shirts. When it gets cold, the Mayans will add a cloak. The Mayans, rich or poor, wore simple gowns and loincloths. But the poor have no gorgeous clothes and no jewelry to decorate. Wealthy Maya men and women will wear jewelry made of small pieces of jade and shells, as well as hair ornaments made of colorful feathers. Mayans sometimes file their front teeth into sharp or other shapes and fill them with small pieces of jade. Tattoos and paintings are very popular in Mayan civilization. Boys draw with black paint, while girls draw with red paint. Priests use blue pigments for tattoos, and soldiers use red and black.

Edit this paragraph "polis and temple"

All the Mayans believed in the same god and spoke the same language. But unlike today's countries, they have neither the same managers nor the same capital. Every city-state has its own king, called "Kuha Aga", which means "divine right". He has the supreme right to rule the whole city-state. The king lives in the palace every day. They make laws, deal with what happens every day, and accept tribute from local leaders. When the king dies, his eldest son will inherit the throne. Jaguar is a very special animal in Mayan civilization. Their fur is very precious and is usually used to sew the clothes of Mayan monarchs. Sometimes there will be battles between the city-states, and each battle will consume a lot of time between the warring parties. The war began with deafening drums, whistles, horns and shouts. Priests will follow the army with idols, which is considered to bring good luck. Maya people all live in or around big cities, among which Tikal, chichen itza and Copan are famous big cities. These city-states were established mainly for the purpose of the Holy Spirit, and also became the centers of trade and entertainment. Most of the residents in the polis are officials, priests, businessmen and craftsmen, while a large number of civilians live in small farms and villages outside the polis. Roads connect the city-states. A large palace built in a polis with polished and dyed boulders. Mayan city-states also have narrow stadiums and towering temples in the shape of pyramids. These buildings are built around the big square where sacred ceremonies and prayers are held. The Mayan Temple is located at the top of the Great Pyramid, and there are steep steps on the four trapezoidal slopes of the Pyramid. Sometimes new temples are built on the basis of old ones. Some pyramids are as high as 6 1 meter.

Edit this sacred ball sport.

Maya's sacred ball movement was held on a long and narrow rectangular field, which symbolizes the earth, and the ball may symbolize the moon and the sun. Players wear many layers of padding when playing to protect them from hard rubber balls. They must hit the ball with their elbows, knees, hips and forearms to get the ball through the stone circle to score.

The Mystery of Ancient Tunnels In the 1970s, an ancient Mayan tunnel was discovered in South America. It is estimated that it is at least 50000 years old, but in fact it is older. The tunnel is 250 meters deep from the ground and hundreds of miles long in Peru and Ecuador alone. The secret entrance to the tunnel is guarded by an Indian tribe. They say this is where "God" lives. They abide by their ancestral teachings and have been here for generations. In the ancient tunnel, archaeologists found many ancient cultural relics, which were placed in many caves of the tunnel. What excites archaeologists more is some metal leaves engraved with symbols and hieroglyphs, as well as stone tools and metal products of different shapes and colors. Unfortunately, no one can decipher these words so far. The wall of the tunnel is bright and smooth, and seems to be polished at right angles to the ground. The ceiling of the cave is flat, like a layer of glaze, not like natural formation, but like the result of some kind of mechanical cutting. There is a "hall" in the tunnel, with a length of164m and a width of153m, in which there are "furniture" such as tables and chairs. Strangely, the materials of these objects are very special, neither steel nor stone, nor plastic and wood, but they are as hard and bulky as steel and stone, and no such materials have been found on the earth so far. There are many metal leaves in the "hall", most of which are about 100 cm long, 50 cm wide and 2 cm thick, arranged one by one, like a bound book. There are many symbols and hieroglyphs written on the metal sheet. According to experts, those symbols are the result of regular stamping by machines, and more than 3,000 pieces have been found so far. There are many patterns made of gold in the tunnel, two of which are pyramids. Next to each pyramid, there is a row of symbols and a pillar carved with gold. This column is 52 cm long, 14 cm wide and 3.8 cm thick. There are 56 squares carved on the pillar, and each square has a strange symbol. Why did the ancient Mayans dig such a huge tunnel? What kind of secrets are hidden in the articles and words? Coincidentally, as early as 1940s, American Ram discovered an ancient tunnel when he was inspecting the dense forest in Chiapas, Mexico. The British research team also found an underground tunnel in the Sierra Madre in Mexico, which can lead to Guatemala. Every dawn, the sound of the underground tunnel is like a drum, shaking the distance; An ancient underground tunnel was also discovered in Azerbaijan, the former Soviet Union. There are some halls more than 20 meters high and narrow arched doors in the tunnel. It is said that wonderful sounds and lights are emitted from time to time in the cave. According to archaeological exploration and ancient documents, archaeologists infer that there is likely to be a global underground tunnel across the Atlantic Ocean, connecting Europe, Asia, the United States and Africa. These ancient tunnels may be the masterpieces of ancient Mayans. Ancient underground tunnels: the most difficult mystery in the world 1942. In March, President Roosevelt took time out of his busy schedule to meet David and his wife, who had just returned from archaeological research in Chiapas, Mexico. Mr. and Mrs. Ram brought a surprising news to the President: they finally found the legendary white-skinned Indian guarding the underground tunnel in Mexico. According to Mr. and Mrs. Ram's memory, when they passed through the dense local forest, they were surrounded by some blue-and-white Indians, asking them to go back immediately. And they have long heard that there are Mayan cities abandoned by drought in the hinterland of Chiapas. The purpose of their trip is to find out the truth of this rumor. /kloc-In the 7th century, a Spanish missionary discovered an underground tunnel in Guatemala, Central America. From the map, it is located under the Andes, and its length is more than 1000 km. In order to protect tunnels, people will not develop them until they have mastered enough science and technology in the future. The entrances of these discovered underground tunnels are closed and guarded by the Peruvian government, and they are listed as world cultural heritage by UNESCO. German writer von Dunken once entered this tunnel. In the tunnel, he was very surprised to see wide and straight passages and smooth walls. There are many exquisite rock openings and gates, flat and smooth houses and halls with an area of over 20,000 square meters, and many ventilation shafts with an average length of 1.8m to 3 1m and a width of 80cm, which appear at regular intervals. There are countless strange prehistoric artifacts in the tunnel, including the golden books mentioned in ancient legends of many nationalities. The rigor, grandeur and magic of the tunnel surpass the wisdom of modern human beings; The writer, who is famous for his bold imagination, was also stunned. He has no doubt that this is the most ambitious project in our world; It is also the biggest and most difficult mystery in the world. Danny Ken took some photos about the tunnel. But he refused to give more details. He just said that he thought that the tunnel was drilled with high-tech ultra-high temperature, directional blasting with electron rays, and some technologies that humans did not have.

Crystal Skulls

1927, a skull made of crystal was found in the Mayan ruins in Belize, Central America, which was even more amazing. This crystal skull is made entirely of quartz stone and is almost the same size as a human skull. Height 12.7 cm, weight 5.27 kg. It was carved from a woman's skull. Maya carved crystal skulls from human skulls, showing mature anatomy and optical technology. And it is made with some collision technology that technology has not yet mastered. From the photo, it seems that this skull is not only very realistic in appearance, but also completely conforms to the skeleton structure of human skull. Its technology level is extremely high, and the diamond mirror hidden in the base is combined with the hand-polished lens, emitting dazzling light. As we know, modern optical technology came into being in17th century, and it was not until the rise of anatomy in18th century that human beings accurately knew their own bone structure. This crystal skull is carved on the basis of a good understanding of human skeleton structure and optical principles. How did the Mayans master these profound knowledge of anatomy and optics? Also, crystal is a timely crystal with high hardness, second only to diamond (diamond) and corundum, and cannot be processed with tools made of copper, iron or stone. Even modern people can only use modern tools such as diamonds to carve this crystal product. It has been confirmed by research that this lens skull is carved by some collision force, but this technology has not been mastered technically. Judging from this strange crystal skull, the Maya mastered the technology quite well. Compared with this crystal skull, the technology that modern people are proud of is really eclipsed! Judging from the development speed of modern scientific theory and technology, I'm afraid it will take at least 50 years or hundreds of years to keep up with the Maya's scientific and technological level! Did the Mayans really make these magical crystal skulls?

Edit this paragraph to explore the mystery of the demise of Mayan civilization.

1839, explorer Stephens led a team to discover the remains of the ancient Maya in the tropical rain forest of Central America: magnificent pyramids, magnificent palaces and highly accurate calendars carved on stone tablets with strange hieroglyphs. Archaeologists have put forward many hypotheses about the mystery of the destruction of Mayan civilization, such as foreign invasion, population explosion, diseases, climate change, etc ....., all of which endow Mayan civilization with a strong mystery. In order to solve this eternal mystery, in the late 1980s, a multidisciplinary team of 45 scholars, including archaeologists, zoologists and nutritionists, traveled all over Guatemala's Peten rainforest area, where jaguars and rattlesnakes even frequented grave robbers. The expedition spent six years investigating about 200 Mayan civilization sites and concluded that Mayan civilization was destroyed by a bloody civil war for wealth and power. The Mayans were not the legendary peace-loving people. On the contrary, in the heyday of 300-700 A.D., Mayan nobles in neighboring city-states were always fighting for power and profit. The Mayan war seems to be a terrible sports competition: soldiers attack other cities with spears and sticks as weapons, with the aim of capturing prisoners and giving them to their priests as a gift to worship the gods, which is a symbol of Mayan society's worship of the gods. Maya society was once quite prosperous. Farmers cultivate marginal fields, terraced fields and swamp rice fields to produce food that can support the population explosion. Craftsmen use flint, stone, bone horns and shells to make works of art, make cotton cloth, carve words on stone tablets, and draw pottery and murals. Commodity trading is prevalent. But since the middle of the 7th century, Mayan society has declined. With the increase of political marriage, other royal brothers except the eldest son are excluded. Some princes left their homes to look for new cities, while others stayed to fight for inheritance. This kind of "throat" has changed from fighting for sacrifices to fighting for jewels, luxury goods, kingship and beauty ... The war is continuous, the lives are ruined, the trade is interrupted and the city is destroyed. In the end, only 65,438+00% people survived. The fall of the palace of Pyrrhus Delus in 76 1 A.D. can be regarded as the beginning of the decline of Mayan society. Las Douspis is the central city-state within 0/500 miles of Fiona Fang/Kloc. It was attacked by enemies from the neighboring city of Tomareto. There are 13 heads of men aged 8 to 55 in a cave, which proves that the city was extinct when it was captured. Eight days later, the winner held a "closing ceremony" and smashed the throne, temple and stereotyped writing. Some nobles fled to nearby Aguadica, a natural fortress surrounded by huge cracks. They lived there for 40 years and were finally captured by the enemy and plunged into disaster. In 800 AD, Adika was already a ghost town. After 820 AD, the Mayans abandoned the Piteng Rainforest, which had been built in countless cities for thousands of years, and never returned to the birthplace of this civilization. The destruction of Mayan civilization has become history, but the warning it provides is worth remembering forever. Today, more than 2 million Maya descendants still live in the lowlands of Guatemala, Mexico, Belize and Honduras. However, the essence of Mayan culture, such as hieroglyphics, astronomy, calendars and other knowledge, has disappeared and failed to be left to future generations. In 2007, archaeologists observed the universe and studied the local rock changes, and found that there was a strong drought every two centuries during that period, which was strikingly consistent with the solar vibration wave discovered by astronomers. Affected by the universe, the sun will have a vibration wave every 200 years, and the high temperature weather will be many times higher than in previous years. Because the political situation at that time was also deteriorating, the problem of drought could not be solved, which eventually led to the demise of Mayan civilization. Of course, this is just a guess by archaeologists. However, as we all know, the Mayans were proficient in astronomy. It would be ironic if the vibration of the sun made their civilization die out.

Edit the possible reasons for the disappearance of this paragraph

1 political marriage, the royal brothers were excluded, and other members competed for inheritance and property, leading to upper-level chaos. 2 the rise of secular culture, the impact on traditional civilization. The plunder and oppression of the Spanish invaders and the coercion of religion brought disaster to people. 4 population expansion, infectious diseases, 5 space migration, giving up the city and returning to the original, is it necessary to transform the new original ecological planet, or is it difficult to travel long distances; Distance requires the quantity and quality of people, and the chaos left behind leads to disaster. The tool is to use the gravity of Halley's comet. The reasons for the disappearance of Mayan civilization are controversial. Most people believe that the earthquake and hurricane at that time, together with population explosion, food shortage, peasant riots and alien invasion, caused the decline and decline of Mayan civilization. However, the exact answer has not yet appeared. The solution of this secret is like a jigsaw puzzle, but it has just begun.
