5 mysterious technologies that have surpassed the modern era for thousands of years Higher, faster, further, humanity is always looking forward What is considered the most advanced technology today will become outdated in a few years However, in the face of the unceasing innovation and advancement of technology, we cannot deny one thing The new is not always better In the distant past of ancient times, there was a system of intelligence in Korea In the winter, from the city walls, where the emperors of China lived in their own time, the city and the harem did not sink in the cold weather when the outside temperature sometimes dropped below 20 to 30 degrees Celsius It was thanks to scientific technology In Olete Taipo, one of the most mysterious ancient sites on the planet People find the sign of a terrifying device I would like to say hello to the audience of Ngom Radio Dear friends, there are ancient technologies thousands of years ago that are still valuable to this day It is said to be technologies that go before the times Exceeding in efficiency and durability And even today we are still using and imitating them Today, I would like to invite you to discover these 5 wonderful ancient inventions Number 1, the ancient heater system Today's journey will start from the palace of Gyeongbokgung in Seoul, Korea This is a white royal palace that has undergone many changes over time Many years ago, scientists were puzzled and puzzled when they found a large heating system under this ancient palace In other words, the heating system of Jisan Ando is extremely smart and modern Ando appeared from the Bronze Age almost 3,000 years ago The process of operating the heating system will start by lighting a stove made of clay The heat of the stove helps heat the stove and has the effect of transmitting hot air And hot pipes are placed at the bottom of the house Warming bricks or stone floors and walls all over the rooms At the beginning of the Joseon Dynasty, the end of the 15th century, the beginning of the 16th century Ando became popular all over Korea, not just in the palace This system helps people get through the cold and hot winter Because of the heating system, people will sit directly on the roof of the house to eat and sleep Today, the traditional Ando heating system has become an integral part of Korean culture It has only changed a little, such as the use of hot pipes and high-tech heating This wonderful technology was also used under the Forbidden City of China 1,000 years ago Also known as Dian Nuan In the winter, the Forbidden City, where the emperors of China lived during the Ming Dynasty, Tang Dynasty and the late Qing Dynasty There was a time when the temperature dropped below 20 to 30 degrees Celsius To heat the rooms inside the palace, the queen would light the coal in a separate room outside The hot air would be transmitted through the pipes leading to the brick building So all the floors inside the rooms of the Forbidden City would be heated The Chinese in the old days also designed the stove to burn the smoke outside In order to avoid the situation of toxic gas In addition, the emperor, queen and emperor used a small iron stove made of white copper outside Inside there is an iron stove to burn coal These hand-held iron stoves are extremely sophisticated This shows the ancient wisdom in the creation of life-saving services However, this is not the most wonderful invention You can look at the ancient Inca burial system below Number 2 The Inca super-Vietnamese burial system The Inca system only lasted about 100 years until they were destroyed by the Spanish in the 16th century When the Spanish invaded Peru, they were shocked to see hanging trees Stretching deep through the deep alleys of the mountains However, this is nothing compared to the agricultural plan and the Inca super-Vietnamese burial system This system not only provides water for the plants, but also provides water for the whole city But still ensure that it is not polluted and polluted The Inca cut into the mountains to make the stairs And built narrow waterways in the mountains They built dams and canals around the mountains In the highlands, around the 1400s The Inca civilization had more than 1 million hectares of long stairs across the Peruvian territory What's more, this system is well-constructed but has never been flooded No matter how much rain The Inca designed a water supply system that leads from the highest floor to the lowest floor They used large and different shapes of stones to create the best structure for water retention and drainage At the same time, they also created a very flexible water drainage system There are three layers The first is the sub-layer The second is the sand layer And the third is the limestone layer These layers allow the water to be drained quickly, deep and not pollute the soil At the same time, when the water is drained The Inca led a line of canals to allow water to flow throughout the city They created a smart water supply system with 130 pipes Therefore, the source of water is no longer mainly dependent on rainwater But also brought back from the Urubamba River in the nearby area This shows that the ancient Inca created a complex and extremely unique water supply system Helped them restore the terrain of the rocky mountains and live harmoniously with nature And one of them is still used and preserved to this day It's amazing, isn't it? The ancient Inca also had a super-duper stone cutting technique Number 3 Ancient stone cutting technology Ollantaytambo is one of the most mysterious ancient sites on the planet Located near the town of Cusco, Peru Here we can find evidence of extremely advanced technologies Used by ancient civilizations thousands of years ago Ollantaytambo is a masterpiece of technology and architecture It is both a giant and a complex city Its greatness can be seen in other ancient buildings Such as Pumapancu, Teotihuacan, and even the Giza pyramid Thousands of years after Ollantaytambo was built Researchers still can't explain exactly How ancient people could excavate, transport, and install giant stones Weighing more than 50 tons to build magnificent buildings Some of the buildings here also show Signs of extremely advanced ancient technology And has been lost for thousands of years Endocene stone cutting technology Looking at Ollantaytambo We see a special point that many people care about On the mountains Ancient people somehow cut out giant stones And very strange zigzag shapes But extremely accurate But the stones are not only giant But also cut very finely Some people say They were created by a device like a laser or a saw In addition, the surface of the stone looks rough But when you touch it, it feels smooth like a mirror That means that some crystallization processes have been used It is possible that thousands of years ago Ancient people already had very advanced technology Not just based on wooden and bronze tools We really missed something in Ollantaytambo How can ancient people cut large stones out of the mountains Still transfer them to the East Move them through rivers Put them on the ground And put them where we stand today Is it a difficult question to answer, right? Number 4 Parts of the body In today's age Feet or hands are not strange to everyone These old parts are created by high technology Look exactly like the shape And have flexible movements This helps disabled people return to normal life As best as possible Perhaps you think that I am lost Because we are talking about ancient mysteries However, what is surprising is that thousands of years ago Ancient people have created these parts For example In 1998 Ancient Iranian musicians Discovered in artificial eyes There is an age 5,000 years ago It was discovered at the Changsari Sokta Crater Located far away from Sistan Between Iran and Afghanistan It has the shape of a sphere with a diameter of only more than 2.5 cm Or the famous old arm of the German knight Goz von Berlichingen In 1504 In the siege of Landshut Goz lost his right arm But luckily After that He was put on his old arm By iron Activated by joint This old finger With joints Can hold a sword Hold tight to the wall And even Hold the whole pine tree In 2007 Ancient Chinese archaeologists Also discovered an old leg Of a medieval man At the age of 2,200 years old At Chopin The left leg of this man was deformed The ribs, thigh and calf Fixed at an angle of 80 degrees He could not stand upright Therefore This old leg Can make it easier for him to walk The marks show It has been used regularly for many years More interesting Archaeologists once discovered The oldest teeth in the world At the San Francisco Tuscany Museum It contains 5 teeth In which The teeth Are covered with a layer of gold Silver And a layer of small teeth Found on the teeth Showing It has been used for a long time So We can see that The teeth And the parts of the teeth Developed in recent years In fact It used to be used by ancient people In the distant past Number 5 New numbers Useful We are talking about a bigger thing Prehistory Is a very old concept From thousands of years ago Or longer Existed in these concepts But it is not a theory But an ancient super science David R Hawkins Is a psychiatrist And a famous American teacher In the work Power vs Force Spiritual energy He has proven the connection Between human diseases And negative thoughts Here We temporarily call it Energy and frequency reduction In the body His research shows The frequency fluctuates From 1 to 1000 With 1 is the lowest And 1000 is the highest Until now The highest frequency fluctuation He met was 700 When a person has a particularly strong frequency The presence of this person This can affect From the school He took an example In the case of Teresa's mother The whole school was overwhelmed When she won the Nobel Peace Prize Why is that? Because her frequency fluctuation is very high From her school From energy Make all the teachers around Dr. Hawkins Conducted a survey Dozens of thousands of cases As his patient All over the world And the results are the same When the frequency fluctuates Of a person under 200 That person There will definitely be 7 Those with high frequency thought Such as compassion Love Patience And gentleness By frequency From 400 to 500 And the frequency fluctuation From 700 to 1000 Is achieved in Those who practice and meditate In fact Under the practice of the East and West Understand that Meditation and practice Can generate spiritual energy With the universe At a lower level Meditation May have the effect of self-healing And reduce the risk of disease It's interesting to go back to the past And see many foundations of knowledge Of the ancients Still have great value For modern people Right? Do you know any ancient inventions Over time As I just mentioned above? Please leave a comment below the video For me to know And don't forget to subscribe to the channel Like Share If you find the video meaningful Thank you for watching 10 ancient constructions go before the times Ancient constructions with large scales Not only challenge the knowledge of mankind But also prove the superhuman intelligence of the ancients Like the 18-story city With a capacity of 20,000 people Lying deep under the ground Or the ancient water pipe Designed for the construction of modern infrastructure Why? Thousands of years ago The ancients knew how to apply modern physics In construction Or is this just a remnant Of very advanced civilizations? I would like to greet the audience of Ngom Radio Dear friends With modern science and technology Humanity today Has built on large structures Sky skyscrapers As well as underground hidden structures However Not until today People can do that Archaeologists have discovered many ancient constructions Thousands of years But have the technology to build beyond the knowledge of today's humanity Right after this Please join me Continue the exploration journey In today's program Number 1 Dolan Tomb 9-story tower Thousands of years The Dolan Temple Hai Tay City, Chenghai Province, China Is a place of endless vastness With the Gobi Desert With tall mountains And vast vegetation The population is small And extremely desolate What is surprising is Under the Gobi Desert Hiding a royal tomb Buried 1,500 years ago This strange tomb Is the Sui Dang tomb Also known as the 9-story tower Belonging to the royal family of the Tsok Tho Also the owner of the Western region In the Tui Duong period Existed from 313 to 563 Locals Advise the excavation team not to go there Because their ancestors used to say This is an extremely desolate tomb of a demon The discovery of the 9-story Dolan Tomb Deep underground Caused the whole excavation team to tremble Because of the scale and complexity of its construction structure This tomb is facing north and south 33 meters high 55 meters wide The front is like a pyramid So it has another name Pyramid Pyramid Or the mountain behind the tomb Looks like two dragons covering this area When digging the area to the second floor Excavators have found more than 700 animal statues A large amount of silk Gold ornaments These silk pieces are clearly patterned And the color is extremely bright Up to now Experts have stopped excavating Because if deeper Very likely to affect the structure of the tomb There is a theory that If you think like this from the beginning Then did not excavate to the second floor Perhaps the excavation team received a warning From some invisible force So they just stopped This is also the reason People call it the power of the tombs Number 2 18-story city in the heart of Derinkuyu 18-story city 85 meters deep in the ground Sounds like a Hollywood sci-fi movie But it really exists It is the city of Derinkuyu Found in the Cappadocia region of Turkey 1968 This is a famous area in the world Because of the wide network of tunnels Leading to different cities Derinkuyu has a complex structure With a capacity of up to 20,000 people Designed to serve many purposes And different functions Like wind tunnel Residence area Vegetable garden Kitchen Living room Bar School Store Church And the cemetery Up to now No one knows Who built this city And why But experts affirm Only those with very deep knowledge About geography Architecture And engineering Can build this miracle Number 3 Longzhu Cave One of the most mysterious underground caves Ever discovered Is the Longzhu Cave, China This site was excavated by farmers By chance in 1992 This is a cave Artificial caves At least 2,000 years old And is one of the largest constructions By people who built underground caves The bigger secret Is that this cave is long With a striking area Of 2,000 square meters And a delicate structure With the highest peak More than 30 meters Up to now Researchers can only know that The Longzhu Cave cave Very spectacular and magnificent With delicate architecture And star Built by people High technology in the past Number 4 The Patra pipeline When it comes to ancient architecture Many of you will immediately think of the Great Pagodas of Russia Temple of the Mirror And the statues of the gods In addition Ancient civilizations Have contributed to infrastructure To serve people's lives And the Patra water pipeline Located in Aksenio On the southwest coast of Turkey It is such a project In ancient times Patras There is not enough fresh water To supply people They have to lead water From a 22-kilometer depth From a nearby mountain Although the construction technique is complex But all based on a basic principle The spring will flow along the path A water channel To limit water contamination When passing through different terrain Ancient engineers Designed a glass pipe Made from hollow rocks in the middle Can be connected to each other By a joint This is also the principle That modern people have used In the water pipe system From the factory From the households When studying this construction carefully Scientists have discovered An interesting thing Some rock components Pipeline Drilled a hole To help ancient engineers Stay clean in the sun Help maintain the pipeline Become easier More convenient After that It will be closed With a corresponding design object This construction When researchers were surprised With the ancient knowledge How did ancient people Be able to apply modern physics In a civil engineering That has been around for thousands of years This is a question Not easy to answer Number 5 Jambhari well Jambhari Is an ancient well In the village of Ambadiri, India It is also called Moon well Or silver well This is one of the oldest And the most famous Of Rajasthan Built by King Chanda Of Chiyo Dai Nekumbar For construction From the 9th century Today's Jambhari Is an architectural institution With 3,500 steps With a contrasting structure Leading to the bottom of the well The well has a square shape The deeper down The more compact Creating a space Like the Egyptian pyramid The steps are all Connected to each other From the ground Down to the water Is 13 steps The level of the stairs Is about 20 meters deep The four sides of the well Are covered with a blue-green layer Giving a cool feeling With a temperature At the bottom of the well Always below 5-6 degrees Compared to the ground Now Jambhari Is one of the famous institutions In the world Number 6 The Bersilker Sitton In Istanbul, Turkey There are hundreds of well That have been preserved From the ancient times Of the city of Kostantinopul The biggest of these wells Is the Bersilker Sitton Also known as The Palace of Darkness With a length of 138 meters Width of 65 meters And can hold About 80,000 meters of water The steps of the Bersilker Sitton Are protected By 336 large stone pillars For a space Of nearly 10,000 square meters Creating beautiful curves Like in European churches In it There is no way Not to mention A few of the top statues Medusa In Greek mythology Medusa Is a very ferocious woman With a curly hair And there is A dragon In the middle Of the well The dragon Is the goddess Medusa And there is A pair of eyes That anyone who looks at Will be frozen Therefore The artisans Put their heads upside down To avoid The people Looking into its eyes Number 7 Mahabalipuram Architecture Mahabalipuram Located in the south of India The white architecture Was formed From the goddess Of King Chilapalava In the 7th century A.D. This architecture Has become An indisputable proof Of the civilization And ancient Indian philosophy When Mahabalipuram Was built Mahabalipuram Includes many Small and large temples Which were built Directly into the large stone Pillars In which The lion The cow Were carved In a very sophisticated And beautiful way This complex Architecture Was able to show The level of technology And the creativity Beyond the imagination Of the modern people Number 8 The Goseck Circle In Germany The Goseck Circle Is the oldest observatory That was built In Germany Nearly 7,000 years ago In 1991 The German government Found something Strange on the ground It looked like There was a giant circle Hidden under a cave 12 years later The archaeologists Realized that It was a fragment Of one of the oldest observatories In the world They named it The Goseck Circle It was located On the same plateau As the famous Stonehenge In the UK 51 North Plateau Another interesting point Is that this circle Has a connection With the Nebula Skydisk An oldest plate Describing the universe The Goseck Circle Is considered To be a big discovery And a proof Of the knowledge Of the ancient Europeans About astronomy With the knowledge Of today's archaeology Number 9 The Sacsayhuamán Tower Is located In the western part Of the old city of Cusco The historical capital Of the Inca Empire Of today's Peru The remains Of the Sacsayhuamán Tower Are shocking And a big mystery To all Researchers Or visitors This tower Is believed To have been built By the Minoans Around 1100 And continued To be completed By the Incas In the 13th century This place Is famous For the dry stone statues Built with massive stones Weighing up To 200 tons Researchers Don't know How these giant stones Were transported To the site At an altitude Of 3,701 meters And how The stones With different shapes And sizes Were placed As if in a game Up to the point That a piece of paper Couldn't be erased Even if there was no Brick or any Sticky material Found Number 10 Canapfirao The world's most magnificent Ancient Diving Channel Canapfirao Is also called The Gadara Diving System This is an ancient Diving channel Built to Provide water To the people Of the Decapo region Of the Greek Empire Of Syria And Jordan Canapfirao Is 170 kilometers long And made of stone This is not only The longest Diving system In the world It is also the most complex System As a giant Technological project This project Shows an impressive Accuracy When the slope Of the tunnel Is 0.3 cm Which means It is only 30 cm On each kilometer A very impressive Standard angle Estimated When completing this Diving system The workers Had to dig More than 600,000 Meters of limestone Equivalent To more than One-fourth Of the total stone Of the Great Pyramid These ancient Projects Are proving The opposite Of most people's Opinions When they say Our ancestors Did not have enough To build the Great Pyramid In the north There is an ancient civilization Very advanced Previously built Anyway They have provided us A deeper look About history And the development of mankind For thousands of years What do you think About these ancient institutions Please leave a comment To let me and everyone know And don't forget to click Subscribe button And the bell next to it To receive notifications When there is the latest program Thank you for your attention And follow The most strange Architectural structures World More than 200 stone towers Were built On the mountain Of the Himalayas No one knows The origin of these ancient buildings Only know that They have a history From 1000 to 12,000 years The statues in Pecha Jordan With architectural architecture Super Vietnamese carving techniques Deep into the stone It is not clear Who built them The Vietnamese Dragon Tower Also known as The tallest tower Southeast Asia Are also the last remains Of the civilization Full of mystery The Khmer Empire Until now Still considered As one of the mighty empires In the history Southeast Asia Former This address has collapsed But once owned The largest territory Southeast Asia The area runs through Cambodia Laos Thailand Welcome you To the radio I am Minh Duc Ladies and gentlemen Running across the planet There are several architectural structures Like buildings Or ancient cities Preserve the memory Of an ancient prehistoric period These buildings Still shrouded In mystery And even We can't even solve the code Who created them Who built them This leads to Many myths As well as legends Let's go with me Discover the weirdest buildings In the world In today's video Number 1 The Himalayan towers The Himalayas Also known as The star-shaped stone tower Are buildings Made of stone Built on the top They are found Mainly in Kham In Tibet There are more than 200 towers Lined up Across the Himalayas Some towers Higher than 60 meters For this reason Some towers are more than 60 meters high. The strange thing is that until now, archaeologists have not known who created them. Even the local people do not know where they come from. Some families have lived here for hundreds of years, but have no information about them. And the library in the area does not have any ancient documents recorded. Researchers have conducted more than 30 stones and wood here to determine the age of the bones. The results show that these towers are from 1000 to 12,000 years old. Some models give results closer to 500 years, meaning that there are towers built later. Based on the age of most towers, it is estimated that most of them were created after the Mongols invaded Tibet in 1240. The local people only transferred it from one generation to another. The age of towers is changing over time. We don't even know what they are used for. There is a theory that they were built for defense or religion purposes and to avoid natural disasters such as earthquakes. 2. Sui Tower Outside of Sui, a village near Lermington, on the southern coast of England, there is a strange tower, not made of steel, built from the time of Victoria. People call it the Sui Tower, and the locals call it the Stone Tower. The Sui Tower was built in the 1830s by the judge Andrew Thomas Pedersen. After retiring at the High Court of Calcutta, it is believed that Pedersen contacted the soul of the famous English architect Sir Christopher Wren, and it was Wren who encouraged the judge to build this structure. The tower is 66 meters high, 5.5 square meters wide, 2.7 meters deep, and there is only a 60-centimeter-thick concrete part at the top of the tower. The length of the concrete walls gradually increases as the tower is built higher. The tower has a hexagonal shape. At the top is a small ring that is led up by a spiral staircase system inside. This 14-story structure is made of concrete and is not supported by any steel bars. Therefore, the Sui Tower is considered the world's tallest steel-free tower. Standing on the top of this tower, you can see the entire English rural area. Pedersen wanted to install a black system on the top of the tower, but this was not allowed because it would make the offshore ships sink into the sea. The Sui Tower is now considered a futuristic architectural work. When it was built, it was not intended to be a place for birds to nest for more than 100 years, until about 45 years ago, this tower was converted into a residence for the population. About 185 kilometers southwest of Jordan's capital Oman, Pecha is an ancient city carved in stone that has been deceiving scientists for many years. There are more than 3,000 lighthouses, tombs and thousands of caves directly connected to the mountain range, about 1,200 meters long and 100 meters deep. The city of Pecha is located in the mountain range, isolated from the outside world at an altitude of 1,000 meters. This is one of the most mysterious ancient cities in the world. It is also known as the City of Roses, a high-end architecture about the art of carving and stone of the ancients, recognized by USCO as an ancient world organ. According to researchers, Pecha is more than 2,500 years old, covering an area of ​​more than 200 square kilometers. It is covered by high limestone, along a normal path between Egypt, Arabia and the Mediterranean. It not only has the advantages of a lighthouse, but also controls the trade routes that pass through it on the Silk Road. Over the centuries, Pecha has been the bloodthirsty road of the Lada-specialists to transport spices through the Mediterranean, India, Africa and the Middle East. In the past, the desert seemed to be completely free and there was no human shadow, there were still its own rules. When crossing the desert, the merchants still had to pay a fee. If not, the price to pay could be that all the luggage was robbed. The city of Pecha is considered a safe ideal place to spend the night. The remaining details in Pecha show that the Nabateans of this city discovered and occupied a precious water source in the middle of the dry desert. They dug ditches to use for Pecha. That's why this is an indispensable stopover on the Silk Road in the past. The Nabateans also knew how to use the dam system, dams and water pipes. Thanks to that, they were rich and powerful with their own fresh water. In 1812, a Swiss explorer discovered this city and announced it to the world. On July 7, 2007, Pecha was recognized as one of the 7 new wonders of the modern world. In addition to the village of Dendai, there are also some other noteworthy details from the Roman era. There are many other stone pavilions with the capacity of thousands of spectators. Pecha is really a very mysterious architecture because we have only discovered a small part, and the most mysterious things are still deep in the heart of the mountain. Number 4. Angkor Wat, the largest city in the world. Angkor Wat is gradually becoming a real picture. It is not only the largest temple in the world, but also the main building of a large ancient city hidden in the forest north of Cambodia, with an area of ​​more than 3.7 km2. And there are many more amazing discoveries. Ancient scholars in Cambodia have discovered ancient and modern cities between 900 and 1400 years old hidden under the forest in Cambodia. In a survey in 2015, the city was discovered by using the latest quad laser technology called LIDAR. They are very impressive. Some of them are as large as the capital of Cambodia. Dr. Damien Evans, an Australian archaeologist, said that this time we have a panoramic view and it is very large, larger than the size of Phnom Penh. From this map, it can be seen that Angkor Wat is part of this large Khmer Empire. These discoveries will change the views about the scale of the Khmer Empire and perhaps it is the largest in the world in the 12th century. Dr. Evans said that civilizations in the past often built buildings in the center of their big city. The Angkor Wat building used a huge amount of stone from 5 million to 10 million cubic meters. This means that the amount of stone used to build the entire city is much larger than the amount of stone used to build all the remaining towers. In addition, the main area has a much larger area than the capital of Paris today. For a long time, scholars have made the theory that this empire is much more desolate than just a complex of Angkor Wat palaces. Scientists have confirmed that there is a huge city surrounded by Angkor Wat palaces. The buildings are full of openings, the wide canals between these blocks create a complex traffic network. The city is large, more than 3.7 square kilometers long. Angkor Wat is not just a temple, it is also a center of one of the largest cities in the world. Studies have also revealed that the city of Angkor used to be the largest industrial capital in the world. In addition, Angkor also has a large canal system and has two giant open spaces located in the east and west. Therefore, it can hold millions of liters of water to water the plants during the drought. So why was such an ancient, majestic city abandoned? This is still a mystery. We can only know that the city of Angkor Wat is one of the largest and most sophisticated cities on the planet of humans. Number 5. Quinta Jarige Ler. This tower is a very mysterious place located in the center of the historical town of Sintra of Buda. This place is recognized as a World Heritage Site because it has a unique architecture combined with Egyptian, Moroccan and Phuocan architecture. Not only that, this ancient tower also has two very strange structures. Namely, the Khai Tam well or the upside-down tower. It is nearly 27 meters below the ground but has no water. There is a spiral staircase inside. Looking down from the well, you feel like you are standing in the middle of an upside-down tower. The large well has nine floors, reminiscent of the sacred works of the Dante Monastery. About nine circles around the hell, nine parts of the hell, nine heavens create heaven. The smaller well contains a series of stairs connecting the layers with each other. This structure also includes a palace, a lake, a cave, a well and a series of other delicate structures. The artistic style of this structure is very strange and not like anything else in the world that we have ever known. In Vietnam, we also have a wonderful place, guys. Number 6, Dương Lòng Ancient Tower. From 192 to 1822, the Champa kingdom created a unique cultural site close to the ocean. Today, there are only ruins of an ancient civilization that has been destroyed and destroyed. The most famous among them is the Dương Lòng Ancient Tower, also known as the Nga Tower in Tay Son, Bình Định. This ancient tower was built at the end of the 12th century, the most advanced period of the Champa art culture. Dương Lòng Tower is the tallest tower in Southeast Asia, with a height of 42 meters, 36 meters for the south tower The tower is made up of large stone pillars, half of which are made up of large stone blocks. The other steps of the Dương Lòng Tower are very delicate in terms of art and detail. It can be said that this tower has the highest artistic value among the buildings of this century. Despite the war and the devastating destruction of the time, the 7-storied, 13-towered Champa still stands as evidence of a golden age thousands of years ago. Interesting, isn't it? Do you want to visit any of the famous landmarks? Please leave a comment below the video for everyone to share. Don't forget to subscribe to the channel and click the bell next to it to receive notifications when there is a new program. In the previous videos, we have learned about the works and constructions of the giant stone building thousands of years ago, and even today it is difficult to make it, such as the Peruvian stone building with the stone pillars. The Puma Bunker in Bolivia with the star-cut bricks. All seem to tell us that the ancients had a very advanced level of technology that was outdated. In fact, they can leave clues and evidence for us. Have you ever thought that they can use energy from the sky and sound? Sometimes, for simple things, we don't think or dare to imagine that it is possible. I would like to say hello to the audience of Ngom Radio. According to traditional science, the ancients could not have modern machines like today to create constructions not only complicated in terms of construction but also complex in terms of workload. They only knew how to rely on basic tools and extraordinary efforts to do everything. In fact, this theory cannot explain all the ancient constructions. But if the ancients used modern tools, why don't we see any old machines being preserved? Did we misunderstand the tools found? Or did the ancients have special secrets to make those tools stronger and more extraordinary? The good news is that recent discoveries seem to partly reveal that secret. And you will be revealed in today's video. The difference in technology First, let's talk a little about today's work to cut and mill stones. People can use constructions such as a drill, a saw, a water mill or a laser. Water mills use a water mill with very high pressure and high speed to cut stones several tens of centimeters thick. A laser cutting machine allows cutting almost all materials using a laser beam, heated by a heat gun and then cut. However, because of the high cost, we can only use it to cut materials. No one uses a laser to cut stones that are several meters thick, because the stone is often very hard and extremely difficult to cut. And when a strong force hits it, it is immediately broken or broken in different directions, causing uneven cutting surfaces. Meanwhile, the tools of the Incas and the ancient Egyptians were quite large Let's look at this perfect hole on an Egyptian granite stone. How did they do it? And how did they create such a perfect convex surface with a hard, solid stone? That is, not to mention the huge, extremely square blocks with a perfect ratio and the large statues of granite with a smooth and smooth surface such as the words Khunduq or the thousands-year-old bottles carved and shaped from a single block. How did the ancients with primitive tools create such complex and accurate crafting tools? Let's think in another direction. We only pay attention to the tools without paying attention to the size. Are those tools not used the way we imagine but they have been enhanced with the power of nature? Scientists have found evidence to explain this. Building technology with the sun and the sun In 1997, the website quininet.com published an email that hundreds of objects look like magic in the Egyptian museum's library. They are made of steel, about 0.2 to 2.7 meters in size, and look like a U-shaped strip connected by a string. When the string is pulled, they will vibrate for a long time. Although this has not been confirmed, it seems to identify the symbol of magic on the wall of ISIS and Abu Dhabi. With the string pulled between the steel bars, the two objects are holding in the statue of the Sumerian are much more ancient. It seems that the ancients knew about the impact of sound and vibration much more than what we know now. In addition, the results of the study show that sound plays an important role in the construction of great structures around the world. Nowadays, research on sound waves also show that vibration can change the structure of objects in different ways. Now, we have begun to understand exactly how the ancients created giant structures all over the world. Can we finally reach the level of that era? It cannot be confirmed for sure. And the discoveries of the ability to use solar energy and sound in the construction of ancient times are really valuable discoveries. What do you think about this topic? Do you think that these are the techniques that the ancients used to build great structures? Please leave your comments below. And don't forget to click the subscribe button and the bell next to it to receive notifications when there is a new video. How did the ancients build giant stones or cut hard stones like steel? Today, we often use polyurethane to build artificial stone structures. It is similar to natural stone but you can only tell when you check their composition. Is it true that these giant stones in Warangal also serve the same purpose? There is also the Kailasanatha temple which is 1,300 years old. It is said that the older it is, the more damaged it is. The stones created by it are not stone at all. According to the local people and masters of this temple, these are polyurethane blocks. The stones here are not natural. They are artificial stones. Today, we don't know their composition. I would like to say hello to the audience of Ngam Radio. Dear friends, in the previous videos, we have talked about the legends about the technology of drilling, cutting and making stone. But are those all the ancient things that have been applied? The answer may be no. The more we study ancient structures, the more we are surprised by the technologies of ancient times. In today's video, we will continue to learn about a very special technology that may have been used centuries ago. It's only recently that we know about it. To begin with, let's start with a controversial discovery in the world of science. The Shocking Legend In the 1980s, a French material scientist named Joseph David Davis proposed a legend that ancient Egyptians did not move giant blocks of stone to pyramids from polypropylene concrete with the support of a wooden pole. He argued that the connection between concrete blocks would always be absolutely accurate when a liquid compound sticks to the nearby blocks. So what is the compound made of? He said it was made from materials that ancient Egyptians easily approached such as limestone, limestone and natural salt. At that time, his theory caused controversy Even a distinguished scholar like Professor Michel Bassoeum, head of the Department of Materials Science and Construction at the University of Rexhill, the United States, was not suspicious. If the real metal tower was made of limestone, humanity has spent hundreds of years to discover secrets. Such a mechanism can be easily detected by a few hours by using a microscope. Unexpectedly, his research took him and his colleagues nearly 5 years with many amazing discoveries. They found that the smallest structure inside and outside of limestone pyramids was not the same as natural limestone. In addition, the glue that connects the stone structure may be silicon dioxide or silicate, calcium and magnesium. In addition, the cementation on both the inside and outside of the stone does not follow the usual order or cycle. Meanwhile, the limestone rarely has such a structure. This suggests that limestone may have been used in limestone, not natural stone, but they were manufactured in the United States. Modern Concrete Technology in Ancient Buildings Do you remember the Puma Palm where there were huge stone in the shape of the letter H more than 1,400 years old? It was made very meticulously. For centuries, the biggest mystery was how the ancient people could cut such hard stones The theory of cementation on top of the polymer has provided researchers with an important suggestion. In 2017, they observed red limestone and andesite under the microscope and found that the stone used in this position was different from geological resources in the area. Andesite is a limestone, but scientists have discovered that it contains a carbon dioxide that cannot exist in limestone because it will evaporate at high temperatures. They speculated that this carbon dioxide was extracted from local plants and then the ancient builders added to the andesite to form a type of cement. The results of the red limestone analysis also proved that this is a man-made product. Inside, they used geopolymer, ferrosilicate, cement for andesite and limestone, which is said to have been placed in limestone for a few months to build structures. This basically proves that the Hakan Institute has mastered geopolymer technology, because only when there is a deep knowledge of this technology can it be allowed to create such blocks of stone. In addition, this discovery is also related to the local legend of the extraction of plants to soften the stone to build the remains. Let's continue to find out the evidence. Revealed from the ancient limestone mine In the city of Wurundjeri The city of Wurundjeri in India has a very strange history from the 12th century. It contains thousands of rocks with many different shapes all over the place. When you look closely, you will be surprised because they are very complex stones structures that certainly cannot be created from basic tools. Among them, the most noteworthy are the so-called Jalli blocks. These blocks have quite a lot of corners. Digging a hole with many corners can be done with simple tools. The problem that shocks experts is when they know their size exactly to every millimeter. This certainly cannot be done by hand, but requires a mechanical device. Not to mention, most of these Jallis are made from black sandstone, a very hard stone, but today we still do not have any equipment that can cut these Jallis. We will have to use computers and CNC machines to create these identical blocks. Did the ancient builders use something like a CNC machine or did they use some other technology? In India, Jallis are not only considered an ancient art, but it is also widely used in rural households today. So how do they create identical designs? And are these Jallis really made from another material that looks like black sandstone? The answer is quite simple. They may not use hard materials such as stone, but soft materials such as clay or cement and cast them into identical blocks. Today, we often use polyurethane to cast artificial stone structures. Similar to natural stone, it can only be distinguished when tested. If you go to any place to cast polyurethane, you will see a lot of polyurethane. Is it true that these giant Jallis in Warangal also serve this purpose? Did the ancient builders use the same technology to cast polyurethane and cast them into the shape they wanted? To understand this, we need to go to one of the oldest Jallis in India. The more repaired the Jallis, the more damaged it is. This Kalasarnatha Jalli tells us what this master said. The stones here are not natural. They are artificial stones. The ancients were very good. They made them. Today, we don't know their composition. This is a disadvantage that the Jallis cannot be maintained or repaired. The statues in this Jalli show some strange details. On the outside, they are carved from distant stones. But over time, their outer layer was cracked, revealing some cracks inside the statues. This is a sign of geopolymer. If these stones were made from distant stones, there would be no cracks inside. Therefore, the ancients probably used geopolymer in the form of liquid or powder and cast them into the shape they wanted. Interestingly, what happened after the construction of this Jalli? The Jalli remained in good condition until 1910, when the archaeologists decided to cast plaster to make new works. However, right after the plaster was cast, the structures began to disintegrate quickly. The geopolymer components reacted chemically with the plaster. Therefore, the statues began to collapse. The archaeologists tried at least 5 times in the previous century to maintain the Jalli, but it did not return to its original state but was really damaged. Fortunately, the structures in Gorengo are still intact because they have not been contaminated by chemicals and help us have a clearer view of the geopolymer technology of the ancestors. The strange stones When observing ancient structures around the world, we find a very strange similarity. Most of them have irregular and partially curved stones like the stones from the Khoker Tower in Cambodia to the Prithvi Swara in India to Egypt, Peru, Turkey. Interestingly, at the walls there are no engravings or other words we can see a lot of stones. Look here, you can see a pile of stones on these statues. But if the statues are engraved, there are no stones. They are completely empty. Another interesting detail, look at this statue, there are no stones here, but the stones of the stones are used in places where people rarely see them. It seems that they are used Similarly, when you build a house and you produce a series of 50,000 bricks, but in it there are 500 broken bricks, what will you do? You don't want to throw away 500 bricks, so you will use them in unimportant places or in places where you can't see them. This is exactly what we see in these structures. The stone blocks are used in unimportant or unnoticed places and in fact they only account for 1-2% of the structure. So what are they? According to archaeologist Covravin Bohan, this is what often happens in mining technology. They are called pits. When we cook some material and pour it into the pit, sometimes the material is not completely solidified, it will create a very common flaw like this. This gives us a deeper look at the stone-making technologies that the ancient builders used. The more evidence we look at, the more we have the basis to believe that people in the past could melt stone or combine stone powder with other materials to create polymer-based concrete blocks similar to natural stone. Dear friends, in addition to mining, cutting, and stone-making technologies, today we learn more about polymer-based technology to better understand the hidden secrets of ancient buildings. We can't be sure which technologies were used in the construction process, but there is one thing that can't be denied that the ancients were not stupid and they had a very advanced technology structure.
