Thousand Pillar Temple – Impossible Ancient Technology Discovered?

 

Hey guys, today we are going to look at one of the strangest ancient sites in India – this is the Thousand Pillar Temple which is at least 750 years old. On first sight, it looks like a regular temple,  but there is something fundamentally different about this temple, because there are no visible joints at all between the stone blocks in the walls of this temple.

This is a large temple, but look carefully as I go from the ground to the top, do you see any joints? This makes people wonder if this entire temple is made of one solid rock, like the Kailasa Temple, but archeologists confirm that it is in fact made of many many blocks of stone. In 1300 A.D , an army of the Muslim King Allauddin Khalji tried to demolish this temple, and they took out many of the stone blocks from the ground and the ceiling, because it was easier to dismantle them, but they could not dismantle the blocks on the walls. If you look at the floor, these are newer stone slabs placed by the Archeology department, and you can see how these blocks are loosely connected. If you compare the modern day stone masonry with the ancient technique, modern technology appears quite primitive, because you can clearly see the joints. The archeology department has been trying to restore the temple from the destruction and graffiti by Allauddin Khalji’s army.

Now, why is this temple called ‘The thousand pillar temple’? Most visitors wonder why this is known as the thousand pillar temple because it doesn’t have a thousand pillars. It is called so because it is made of one thousand blocks of stone, this is the actual reason why this name is used. But even in most sophisticated temples like the Lepakshi temple, we can see clear evidence of joints between the blocks, but in this temple, the joints are not visible. What is fascinating is that there was no cement, mortar, or glue used to join these blocks. How did ancient builders achieve such an extraordinary level of jointing, many centuries ago? What kind of technology existed and  how was such a temple built?

The underlying technology is this: Ancient builders created a complex interlocking system with at least a dozen different cuts in each stone block. These complex cuts maximize the amount of surface area shared by the connecting blocks, and will create an extremely tight fit. This is hard enough to do between 2 stone blocks, but imagine using several stone blocks on all sides and how many cuts would have been needed to connect 4 or 5 blocks together.  I mean, this is just an extraordinary technology. This can be done on wood, but how did they manage to make these cuts on large stone blocks many centuries ago? Making these cuts is one thing, but the level of precision, to make these joints invisible can be achieved only with advanced machines.

We can clearly see that building a massive temple with no visible joints is impossible with primitive tools. Did ancient builders use cutting, drilling and polishing tools, just like today? If so, do we have any evidence of these tools in the temple itself?

How about these carvings which resemble modern drilling and polishing tools? In most temples, we usually see carvings of Gods, but in this temple, we can see these tool like carvings, with a conical, striated top with a long shaft, which is remarkably similar to modern day tool bits.

Just compare these carvings with today’s tool bits side by side. You have to admit there is an uncanny similarity. Is this a coincidence, or did ancient builders use tool bits just like us, to make these precise interlocking system?

The pillars in the temple confirm that drilling machines were in fact used. There are very tiny holes drilled on these pillars. My friend is struggling to send a thread through the small holes, but these holes are too small even for a thread. The priest is happy to help us, he picks up something thinner than a thread and inserts it successfully through these holes.

If you think these carvings are not drill bits, how do you explain such tiny holes carved on the pillars? How do you explain the construction of an entire temple with no visible joints? Were they created with advanced machines, or with simple tools like chisels and hammers?

800 Year Old Ramappa Temple shows Rock Melting Technology?

Hey guys, today we are going to examine the Ramappa temple which shows some solid evidence of Rock Melting Technology. Here you can see Lord Krishna playing his flute, and his feet is touching a leaf of this tree. And this beautiful woman is leaning on the stem of the tree. What could be the meaning of this? If Krishna was really playing his flute, the music he made would travel through the tree. If I tap on the stem, it makes a strange metallic sound. This is made of one solid rock, but yet it makes different sounds when tapped in different parts of the tree’s stem. Note the difference in sound. And if you tap on other areas of the same rock, there is no sound.  Of course, this is not a coincidence, the ancient builders clearly wanted us to know that this cylinder makes musical sounds, this is why they carved the symbol of Krishna playing his eternal musical.

But is this structure a carving? All historians and archeologists claim that everything in this temple was manually carved by hard labor. But how do you carve a cylinder on rock that makes music? And even more interesting, how do you carve a cylinder which will make different notes when tapped in different areas? And notice the width of the stem, it has the same width from top to bottom. The different sounds are not created because of the variation of size or shape.

Sculptors and Stone Masons confirm that there is no technology today, to carve a single rock which can make different sounds, when tapped on different areas. But how was such technology used at least 800 years ago, in this temple? The only way to create such different sounds is by altering the density of the rock, by melting the rock and molding it into a desired shape. But is it even possible to melt rocks and make it into different shapes?

In 2016, University of Buffalo demonstrated something strange. They put rocks in a furnace, heated it to over 2500 degree Fahrenheit, and made it into a liquid. In fact, nature does it all the time, it throws out liquid lava whenever there is a volcanic eruption. When scientists at University of buffalo poured this molten rock out, they gathered it into a simple cast made of sand. You can see the molten rock quickly fills up and takes the shape of the cast. This is exactly how we make metallic objects like swords and weapons for example. Did ancient builders use the same technology of melting rocks and mold it into desired densities, this would be the only way to make it create different sounds in different places.

What’s really interesting is that University of Buffalo chose the same type of rock as the ancient builders, they are both basalts. Basalt Rock has properties that are ideal for melting and casting into different shapes.

But this temple has another interesting evidence of Rock Melting technology. The pillars in this temple are quite extraordinary with very complex designs but there is one piece that stands out. Not because it is carved, but because it has been left blank, while all the other pieces on the same level are carved. And it shows something very strange, it shows a defect in molding technology. Let’s take a closer look at this surface, it has extraordinary polishing, but this surface is not perfectly flat. To understand this, you have to examine it by looking at it from a lower angle. The surface has a curvature, with a concave defect on it. This is why it looks bent out of shape, like a piece of plastic. It is impossible to make such a smooth, concave cut on rocks with manual tools or even electric saw, and it cannot be accomplished by hand polishing.

This is a common defect caused in molding process, this is called Warping. When we mold objects, the liquid sometimes will cool at different rates in different places. This will cause the object to become bent out of shape. And this is exactly what happened here, this was a defect made while melting and cooling the rock. The ancient builders recognized this was a defective piece, this is why they did not carve anything on it.

Now, remember, I showed you the floating rocks which were used on the tower of this temple. These bricks were created by heating mud to a very high temperature, and adding other ingredients to make them light weight. You can click on the top right corner to see the floating rocks. From all these evidences, we can clearly see that ancient builders were using rock melting technology.

Evidence of Ancient Machining Technology at Warangal Fort?

Hey guys, this is an ancient site called Warangal Fort and you are looking at some of the most amazing carvings to your left and right, carved at least 800 years ago. But your eyes are naturally attracted to what’s in the center, and you realize that this cylinder is completely out of place. Now, why do you feel this way, why do you think this lingam is an Out of place artifact?

Because your brain instantly and intuitively knows that this lingam could not have been made without machines. This is why it looks so odd. All these brilliant carvings around this, can be made with simple tools like chisels and hammers, but this cylinder cannot be made with primitive tools, such a perfect cylinder can be made only with high tech machines.

This is not where it was originally found. Archeologists unearthed this lingam which was buried for many centuries and placed it on this pedestal which is carved with simple tools. While digging up this lingam, these scratches were made on it, and examining this lingam using precision tools revealed something shocking. It is a perfect cylinder with no visible tool marks at all. How was such precision achieved in ancient times?

Look at the level of finishing, I can use the top of the lingam as a mirror. I am not going to use this priceless piece for demonstration, but I will pick something less polished instead. How about this pillar on the same site, the finishing doesn’t look as great as the lingam, but when I pour water, you should be able to see my reflection. Imagine how fantastic this would work on the lingam. And Lingams are almost always placed facing east, so imagine how it would look when the first sunrays fall on it.

Now the real problem is in finding out how ancient builders made this lingam 800 years ago. Is it possible that they chiseled it into a crude cylinder, and then polished it manually with simple abrasives such as sand, to achieve this level of perfection? But experts who examined this lingam with precision instruments point out to something extraordinary. The roundness or concentricity of the cylinder, the lack of taper, and the straightness of the cylinder, were so perfect, that they concluded it cannot be achieved with hand tools at all. Such precision can be achieved only with machines.

Now, let me ask you a question, can we make a perfect cylinder today, with simple tools? Forget that this lingam is made of black basalt, a very hard rock.  Imagine this is as soft as clay. Can we make a perfect cylinder using clay, simply by shaping it with hand tools? Engineers confirm that making a perfect cylinder is impossible unless we use a rotating mechanism, at least as primitive as a potter’s wheel. The only way, even to make a clay cylinder is to place it on a rotating wheel. So, we can be sure that this cylinder, was not made by chisels, but a rotating mechanism was definitely involved. Now, the natural question is, did ancient builders place this lingam on a potter’s wheel and rotate it manually, and make it into a perfect cylinder?

We are going to forget that this rock is very hard, and we are also going to forget that we would need a harder tool like steel or diamond to work on it. Let us simply assume that the ancient builders did have steel or diamond tipped tools. We are only going to focus, if we can recreate this cylinder today, by manually rotating it on a potter’s wheel.

Human beings cannot turn a wheel for more than a maximum speed of 150 rpm, if we place a rock of this size and make a wheel accordingly. But engineers confirm, that if such a slow speed was employed, the cylinder would be full of circular tool marks, and would look nothing like this lingam. To achieve this level of perfection, the cylinder would have to be rotated at a minimum speed of 2000 rpm, which is 13 times faster than what is humanly possible. So, it is impossible to create something like this without using advanced technology. This leaves us with only one question: what kind of machines did ancient builders use? Perhaps the mystery can solved by looking at this strange symbol, carved on the lingam itself.

World’s Smallest Carvings found in Ancient Indian Temple – Evidence of Machining Technology?

Hey guys, I am at the Darasuram temple in India which is 850 years old and here we can see the smallest carvings in the world. Let’s take a look at this bull carved on one of the pillars. This is about 2 inches wide, but it also shows all the features of a bull. You can see the hump, the horns, ears and eyes, there is even an extended tail,  but look carefully, and you can see the Hoofs, and even the nostril, which is just 1 millimeter wide, carved on it. Now, compare this with the carving of the largest bull in the world, this is also situated in India, in a place called Lepakshi, which is about 300 miles away. This bull is nearly 15 feet tall and 27 feet long. The smallest carving of the bull is so small, that you can place 10 of them inside the toenail, or the dewclaw of the largest bull.

But this 2 inch bull is not really the smallest carving in the temple, some of the carvings are even smaller. This carving is less than 2 inches tall and shows Lord Shiva and we can even identify the weapons and objects he is holding in his multiple hands. Here is a lion which is just one and a half inch long, it is a shame that the temple has gone through many centuries of corrosion, many of these carvings have deteriorated. Here is the dancing elephant god, which is even smaller, he is just one inch long. You can see his crown, pot belly and his arms and legs in a dancing posture. Of course, we have to wonder how ancient builders were able to create 1 inch carvings, 850 years ago. Remember I showed you the skulls in Hoysaleswara temple, these are also one inch wide. They are completely hollow and you can pass a twig through one of the ears and can pull it out through the eyes.  Were these amazing carvings created using advanced machines or with primitive tools?

But there are carvings even smaller than this at the Darasuram Temple, here is a  carving less than 1 inch wide and actually consists of two figures, Lord Shiva and his wife in a sitting posture. This means that each figure is less than half an inch in size. Even today, you can see that people smear saffron powder on this carving as a ritual, this ritual has corroded this carving to a considerable extent, but even after eight centuries, we are able to identify these half inch gods because of their features.

But all this is nothing, because we are only looking at the full carvings, we have to examine the details on the carvings to really appreciate ancient technology. Here is Lord Shiva in the form of a beggar, and look carefully and you will see a begging bowl in his hand. This bowl is carved to the size of black pepper or pepper corn, which is just 4 millimeters wide. Here is the wife of Shiva and you can see the religious dot on her forehead, this less than 2 millimeters. You can even see the smile on her face, Some of the details are so small even to capture with my camera, but if you visit this temple, please do examine these pillars. But be very careful, because – see these designs, which look like Egyptian pyramids, the tips of these pyramids are less than 1 millimeter wide and they will prick you like needles. And this is after eight hundred and fifty  years of corrosion, so imagine how sharp they must have been, when they were first created.

But the question is, how can anyone create needle sharp carvings on solid rocks with primitive tools like chisels and hammers?  I mean, less than 1 millimeter wide? How did ancient builders accomplish this? Showing emotions if the figures are smiling or frowning on one inch carvings? Half inch deities, recognizable after 850 years of corrosion? A bowl the size of black pepper, just 4 millimeters wide? Sharp points with less than 1 millimeter that can still prick like needles? Were these created with primitive tools or were ancient builders using advanced technology?

Please let me know your thoughts in the comments section.

Mysterious Holes Discovered in Hampi Vitthala Temple – Why?

Hey guys, I am at the ancient Vitthala temple in Hampi, and I just found out – there are strange holes drilled all around the temple. It appears that no one has noticed them, because they are not easy to find, unless you examine these walls very closely. These series of holes are just about a centimeter wide. How did ancient builders drill these holes on granite, which is one of the hardest rocks in the world? Today, we use diamond tipped drill bits to create such holes on granite, but how was it done in ancient times? But there is something much more fascinating. Directly above this series of holes, we can see another row of holes, a little bit bigger than the ones below. And there is a third row of holes right above this as well, making the pattern much more complex.

But the most important question is not how they drilled these holes, but why? Why were these holes drilled all around the temple? Archeologists say these were created for mere decoration, for simple reasons like placing flowers or incense sticks all around the temple, but these theories are not convincing.  Is there a way to find out if these holes were made for mere decoration or if they were an important part of the temple’s design? See, the ancient builders were extremely intelligent, they predicted these structures would be destroyed in the future by human beings. So they created a small 3d model of the temple within the temple itself which details the most important aspects of the temple. Here you can see that this model shows how the original temple looked before it was destroyed by invaders. It was complete, with multiple levels and finished with these objects called Kalasha which is how a finished temple would look. But why am I randomly showing you this model, while discussing about the holes in the temple? Because, if these holes around the temple were carved for a very important reason, the 3d model would also have these holes. If they were drilled for mere decoration, it won’t be detailed in the model because the model only shows you the most important features of the temple.

So, I examined this model to see if there are any holes carved on it, and I find exactly what I am looking for. Here are a series of very minute holes carved in the model, these holes are actually just 1 millimeter wide. I think I have just discovered the smallest holes ever drilled in ancient times. I mean, 1 millimeter holes on granite, created by ancient builders – How is something like this even possible without the help of machines? Remember, this whole city of Hampi is full of evidence about ancient machining technology and I showed you how they used lathe machines in my previous video.. you can click on the card on the top right corner to see it.

So these minute holes on the model prove that the holes were not created for mere decoration, but an important part of the temple’s design. But the big question that needs to be answered is this: Why were these holes drilled all around the temple? Remember, I have shown you something very similar in Brihadeeswara temple which was built a thousand years ago, and this structure also has these minute holes all around its base. Why do these ancient temples have minute holes drilled all around the base?

To understand this, we have to examine what ancient temples actually represent. You might wonder why ancient Indian temples always  look like rocket spacecraft, well they were in fact designed specifically to look like spacecraft. The main structure inside any temple complex is called Vimana, which actually means aircraft or spacecraft.

All Hindu temples have this Vimana, which is always aerodynamically shaped. This structure at Hampi has been destroyed, but from the model, we can clearly see that this Vimana is also aerodynamically shaped with multiple levels.

If you look at the base of a modern day rocket, you can see something very fascinating. They always have multiple holes at the bottom. These holes are called exhaust nozzles, and these multiple holes are important for balancing and changing the direction of the rocket. These multiple holes are the reason why well-designed rockets go straight up and follow the desired path, while home-made rockets with just one hole will almost  never do that. Without going into too many details, unlike home-made rockets which use fuel in just one chamber, advanced rockets make sure the fuel is distributed into many small channels. And we can see the same design on this temple as well. I am pouring water, but assume that this is fuel and watch what happens. The fuel will be distributed though the bigger holes on top, and each bigger hole actually has a separator in the middle, which will make the fuel into 2 streams and these 2 streams will be channeled into the smaller holes at the bottom. So, imagine what happens when fuel is released from the center of the Vimana, there would be thousands of fuel streams distributed all around the structure, which will create a very balanced propulsion.  Of course, these structures are megalithic models of actual spacecraft. Now we can understand why the holes are so important, that they were drilled even on the miniature model.

Once we realize that this Vimana is a rocket model, we can start understanding many different carvings around it. We can see lions breathing fire right next to these holes. But why are the flames going down instead of going up? Light a candle and the fire will point up, now  invert the candle and the flame will still point up, because flames will always point up. The only way for fire to point down is by creating fuel powered thrust, just like a rocket. You can see the same carvings of fire breathing lions in Mahabalipuram, and you can see a multi-stage rocket carved with all the details. You can click on the top right corner of the video to see it.

So, what do you think? Why were these holes carved all around the temple, at the base? Please let me know your thoughts in the comments section, I am Praveen Mohan.

500 Year Old Machine Found in Hampi, India

Hey guys, this is the ancient site of Hampi that has been abandoned for at least 500 years, and here we can see this rock that shows solid evidence of machining technology. These perfect circular marks on this rock can be produced only with machines. This process is called facing, and we use the same technology today using lathe machines. It is covered with dirt when I found it, so I cleaned it up. Now, If you look at these circles, they are perfectly concentric and there is no deviation, no chipping in the rock, very similar to modern day technology. The rectangular slot in the center proves that this rock was machined using lathe technology.  So, how was this created at least 500 years ago, at a time when historians claim there was no such technology? Were ancient builders using high tech machines many centuries ago, just like today? If this is true, we should not only find finished products like this circular rock, but we should also find  the entire mechanism that was able to create this finished product. Is it possible that the entire mechanism, the lathe itself can be found in the same area?

Now, if we take a step back and look at the entire picture, it has some very interesting components. It has two posts with circular holes near the top, which obviously means that a cylindrical rod was inserted between them, like this. This is a simple model that I am recreating, which I will show side by side, so you can understand this better. Nearby, we can see a long rectangular slab, with a hole in the center. When I measured the length of the slab, it matches exactly with the distance between the two posts. What does this mean? This means that the slab would fit perfectly between these posts. I am using this green rectangular styrofoam block which represents the slab in my model. So, the set up would look like this.

If a metal tool was placed on this cylinder, pointing downwards, it looks like a modern day vertical lathe machine. I am going to use a pen for the metal tool in my model. This rectangular slab would be the base plate on which circular rocks could be placed and machined. Here is a simple round object which represents the circular rock and I place it on the rectangular slab, and if I rotate the circular rock, and lower the tool from the top, we can create these identical tool marks. See the similarity of the circles between this model, and the actual rock.  My model has not rotated on a perfect axis, so you see that the circles are not as good, but the work of ancient builders was perfect. This set up actually proves that ancient people used vertical lathe technology, at least 500 years ago.

What’s even more interesting is that you can see some circular wear and tear on the base plate as well. Look at the base plate, you can see these half circular marks caused by the rotating objects which were placed on top of it. The other half shows no such tool marks, because these marks were created by accident, by friction from the rotating objects placed above. You can see the same marks beginning to form on my model as well.

All these evidences clearly prove that machining technology, specifically vertical lathe technology was used in India, at least 500 years ago, and some archeologists even say this site was built 2300 years ago. So, I think I have just discovered the oldest machining set up, known to mankind, and it is lying in plain sight, abandoned and covered in dirt.

So, why did ancient builders need this type of advanced technology? What did they create using this technology? Is it possible to find the products of this machining in the same site? Here is the majestic well nearby, created with pyramid shaped steps all around, with machining perfection. Archeologists say these were created with hard labor, chisels and hammers. But is such a precision possible with simple tools? Is it possible, that these were made with machining technology? Were many of the unexplainable megalithic structures in India, made with machines? Remember, I showed you the machine made pillars weighing many tons at Hoysaleswara temple, you can click on the top right of the video to see it.

But In this abandoned site of Hampi, we can find  a lot more strange stone artifacts than any other temple. Here we can see two massive doors created out of solid granite. Again, they look like they have been created with machines. But there is something much more interesting, these doors were not created for mere decoration, these stone doors weighing 10 tons each, were used as actual doors in ancient times. There are hinges for swinging the door, and even slots for locks. Did ancient builders use rocks for everything, just like how we use metals and wood today? Today most of the things we use like doors and furniture are made with machines. Modern buildings are also created with machines, with very little manual labor. Did ancient people build temples and other structures the same way, but used rocks for everything?

So, what do you think? Did ancient builders use machines many centuries ago, just like today? If they did not use machines, how do you explain these circular tool marks, lathe setup and megalithic structures finished with such precision?  Please share this video with your friends, because I think we have just found the world’s oldest lathe technology.

The Secret of India’s Ancient Rock Cutting Technology – Machines?

 

In this video, I am gonna show you the real technology behind India’s ancient rock cutting techniques. By the end of this video, I hope you will agree with me that these brilliant temples were not created with primitive tools. Archeologists insist that these massive rocks were cut with no more than chisels and hammers. First, Let’s take a look at their theory of how ancient builders cut huge rocks. After a rock is chosen, they would carve a series of holes that is about 1 inch wide and 2 inches deep. Then, they would place wooden wedges and hammer them all in. After this, they would pour hot water on the wedge and the wedge would expand inside the rock. If they keep pouring hot water on these wedges every day, the rock would eventually split into half. Now this, not only works for small rocks, but will also split huge rocks like the one I am standing next to. This rock is 25 feet wide and 15 tall, but if you look closely, you can see a series of chisel marks on top. And you can see how even a huge boulder like this can be cut using simple things like wedges and hot water.

This is pretty convincing evidence, so why am I roaming all over ancient Indian sites? Because, to cut a rock using this technique would take months! The ancient builders have to keep pouring water for many months to get this rock to split into two halves. However, we have documented evidence that many of the temples were built in a few years! If it takes several months to split one rock into two halves, how were these brilliant temples, made of thousands of huge rocks, built in just a few years? The numbers simply don’t add up. There must have been some other technology to cut these huge rocks out of these hills and mountains.

I got the first glimpse of a totally different technique of rock cutting in the hills of Hampi, in South India. There is a drill mark which is about 1-2 feet long. There are no chisel marks on this rock whatsoever, and you can see that this rock has been sliced into half. If this is an ancient rock cutting technique, it changes everything we know. However, is this really ancient or was it done in recent years?

I must find more evidence of this technique because experts will dismiss it as something that has been done in the last 10 years, with modern machines. So, I decided to go to Mahabalipuram, which is a ancient site that is protected by the department of archeology. Mahabalipuram stretches for many miles, and rock cutting has been banned for the last 50 years to protect the ancient monuments in this area. Let’s go deep into the woods, and see if we can find the same rock cutting technique. Here, we can see the same type of rock cutting technique, where you see one single drill mark, and the rock has been split open. You can see how a series of this drilling was done on different rock faces, and the rocks have been cut open. This was not done in recent times, because there are trees and bushes growing in the place now, where the other half of the rocks once stood.  So, this is in fact, the ancient rock cutting technology – Drilling a hole into a huge rock and splitting it into half.

And I also found some unfinished rocks, very near to the ancient monuments of Mahabalipuram which proves that this technique was used at least 1300 years ago. You cannot see them on finished monuments because, these drill marks would have been polished and removed. We can see these same drill marks on the unfinished rocks. This huge rock standing nearly 20 feet tall has been split into half. And you don’t see any chisel marks on the sides, just one single drill mark. If you look closer, you can see that a drilling tool has been passed straight into the rock, around the height of 10 feet, which has split the rock open. This conclusively proves that this is how the ancient builders cut the rocks so fast. While wedges and water would take months to cut a rock, drilling through these rocks would split them open right away. This is why, ancient builders were able to build massive temples like the Kailasa Temple in just a few years.

So, this proves that this is how ancient rocks were really cut fast, but this raises many interesting questions. All the rocks you have seen cut using these technique, are made of granite, this is the hardest rock in the world. Today, we use diamond tipped drill bits to drill through granite. Ahat primitive tool could drill through these massive rocks for more than a feet? Were advanced machines used thousands of years ago, just like what we use today? If you look at these tool marks, it is very smooth and reminds us of modern day drilling. This kind of smooth drilling into granite is not possible, unless you have high powered machines. What kind of technology existed back then?

Were machines used in Ancient India? How else do we explain this rock cutting technology? Please let me know your thoughts in the comments section. I am Praveen Mohan, Thanks a lot for watching, don’t forget to subscribe and I will talk to you soon. Bye.
