How were the Egyptian pyramids built? | Nikola Tesla's theory and the mystery of Orion's Belt!
A building is being constructed with stones. Each stone weighs as much as an elephant. Each building requires around 2.3 million such stones. Managing such a massive project today would be tough. But somehow, about 4,500 years ago — without any electricity, diesel, octane, or AI-powered tools — a mega project of this level was built right here on our Earth. What we today know as the Pyramid.
Who built it, for whom it was built — that's mostly known. But the question arises: how was it built? And trying to find the answer to this "how was it built" question, we get into a bit of trouble. Common sense says that the people of that era shouldn't really have had the capacity to execute such a massive mega project. More importantly, Egypt's pyramids are almost accurately aligned with the stars of Orion's Belt and Earth's True North simultaneously.
How did they achieve such precise geometric measurements? And why did they do it? Was there some kind of science behind building these pyramids that has been lost over the course of time? Even Nikola Tesla had given his theory about the pyramids — and why it was built. Another big question: could there be a hand of some other race besides humans? After all, Egyptian pharaohs claimed to be descendants of gods.
How were the pyramids built? What is inside these pyramids? Why even today we haven't been able to unravel their full mystery? Today's video is going to be very interesting covering all of this. So, let's get started.
Pyramids Are a Global Phenomenon
When pyramids come up, we imagine a massive structure standing in the middle of the desert. But pyramids are not only in Egypt — pyramid-like structures have been found in Latin America, China, Europe, and even Antarctica. That means at one point, pyramids were actually a global phenomenon. How this could happen thousands and thousands of years ago is also a question.
The Scale of the Great Pyramid of Giza
But the biggest question comes about the size of the pyramids. For example, let's talk about the Giza pyramids. The largest pyramid of Giza is Khufu, which we also know as the Great Pyramid of Giza. 481 feet tall, meaning equivalent to a 40–45 story building, spread over 13 acres of land. For nearly 3,800 years, it was the tallest man-made structure. This pyramid was built with 2.3 million granite blocks, each weighing approximately two and a half tons.
Imagine for a moment — the trucks we use to build houses typically weigh around one and a half to three tons. This pyramid was built with stones equivalent to the capacity of 2.3 million such trucks.
Three Key Questions
Three main questions arise here. The source of these large stones is not in Giza. So how were they brought to the construction site? There were no trucks back then. Even if they were somehow brought, how were such heavy stones lifted so high up? And even if they managed to lift them, how were the stones placed in such precise alignment?
How the Pyramids Were Actually Built
First things first — this work was not done by aliens. It was not done with any special advanced or forgotten technology either. The Giza pyramid and all other pyramids were actually built by human hands.
The Role of the Nile River
The Nile River is a very big factor here. Just as Egyptian civilization couldn't have stood without the Nile, similarly, there would be no pyramids without the Nile. From surviving papyrus fragments of Inspector Merer's diary from 4,500 years ago, we get his written experiences, where he speaks of massive stone blocks floating on rafts along the Nile River.
And the way the Panama Canal works today, in the same way, the stones were lifted into the pyramid one by one. Now I said this very easily, but doing this was a massive undertaking.
Transporting the Limestone Blocks
At one time, the outer walls of this pyramid were made of massive limestone blocks. These were brought via the Red Sea. It is believed that artificial canals were cut from the Red Sea all the way to Giza to easily bring these blocks, and through them, these massive blocks were transported by boat. An entire port was built there temporarily.
Then those blocks were lifted step by step to the top of the pyramid using a water elevator system. Alongside, wet sand was used for horizontal movement — meaning a liquid like water was sprinkled on the sand to reduce friction so that the stones could slide very easily.
The Ramp Theory
However, in 2018, archaeologists discovered a ramp system called Hatnub dating back nearly four and a half thousand years. This ramp gave rise to the idea that perhaps the Egyptians used ramps to lift these massive blocks. But this theory also has problems. To lift stones to such heights, a ramp of five to ten degrees angle would need to be built. Calculations show that such a ramp would need to be several miles long.
Two theories are proposed as solutions to this. Number one — the Spiral Ramp Theory. According to this theory, the Egyptians built winding slopes around the entire pyramid, made slippery with wet sand and mud to push the blocks up. But questions remain here too about how the spiral ramp would work at the corners.
French architect Jean-Pierre Houdin suggests that the Egyptians built external and internal ramps, where using pulleys and levers from both inside and outside, the blocks were placed in perfectly precise positions.
According to our understanding, the Egyptians had not yet invented gear technology at that time. But this entire theory becomes rock solid if we can connect gears and pulleys. However, since no evidence of such a thing has been found so far, we're actually not sure — whether the water elevator system or the ramp system was used to lift these massive blocks.
Organized Labor
But all of this proves that building these pyramids was not a random thing. It was a massive project where labor was distributed in a very organized manner. In fact, the way we work on mega projects today, perhaps that's how work was done back then — and naturally, a lot of people were involved in this work.
One notion had long existed that slaves were used for this work. But artifacts found from an abandoned village called Heit al-Ghurab, buried in dust next to the Giza pyramids, reveal that Egypt's most skilled laborers were actually used for this work.
Ancient Is Not Equal to Primitive
But this entire thing is of course a theory. We're thinking this work happened in Egypt. But pyramids are not just in Egypt, they exist in many other places too. Without advanced tools, how could such massive structures rise in those other places?
Here we must accept one thing — ancient is not equal to primitive. Just because this work was done 3,000–4,000 years ago doesn't mean there was no technology or brain back then. That's not the case at all.
This claim of "made by primitive people or aliens" actually comes from this very place — that perhaps it was simply not possible for humans to do something like this so long ago. But that's actually wrong. It's not like one day they suddenly felt like it and built a pyramid. Rather, it came through countless trials and errors.
The Evolution of Pyramid Design
"The Great Pyramid of Giza — one shot, one kill"? But no. The story begins 4,600 years ago, with the world's oldest stone structure — the Pyramid of Djoser. This pyramid was built under the hands of King Djoser's counselor Imhotep. Stones were placed on a flat surface and gradually raised, which we know as a step pyramid.
Then came the Meidum Pyramid. Built by Pharaoh Sneferu, this pyramid added a limestone casing to the step pyramid style. But it was not structurally sound — the outer limestone blocks collapsed. Learning from that, Sneferu built his Bent Pyramid. Starting at a 54-degree angle, when he saw that the structure wasn't holding, the angle was changed midway to 43 degrees — which is why it looks slightly bent.
This shows that the Egyptians knew very well about this matter of geometric measurements. Taking the lesson that building at a 43-degree angle is safer, the next pyramid was built, which we know as the Red Pyramid. And after that came the Pyramid of Giza — all previous knowledge was used, plus the pyramid was built at a 51-degree angle for stably placing the limestone blocks.
How Were the Pyramids Aligned So Precisely?
So, one thing remains. How are the pyramids so precisely aligned with Earth's True North? Archaeologists had been searching for this answer for many years. In 2017, a paper published by engineer Glen Dash gave us the answer — the Equinox.
On two days of every year, the Sun is positioned exactly in line with our equator. This makes day and night almost equal. On the day of this equinox, if we place a stick in the ground and start measuring its shadow throughout the day, a curve will be obtained. And when this curve is done across a field as vast as the Earth, it becomes almost like a straight line. This process is called the Indian Circle Method.
Now you might ask how we became sure that this process was used? Well, in this process a curved line is turned into a straight line, meaning there is a slight deviation from the actual curve. Glen Dash proved that the exact same deviation exists in the positioning of the pyramids.
But the thing now is that we have no plans or documents from that era. So yes — the question remains as to how they actually did it.
Mysteries Inside the Pyramids
The Lighting Mystery
But beyond this, pyramids have given rise to many other questions. When we first started entering the pyramids in Egypt, we noticed one thing missing from the doors and corridors — there is no arrangement for placing torches. By our calculation, each pyramid took about 30 years to build, and during this time, work was done inside as well. That can't be done without light.
The Hydroelectric Theory
Researcher John Cadman claimed that the pyramids were used as hydroelectric power generators. According to him, water from the Nile was channeled into the pyramid, taken through its underground tunnels and chambers, and let out, generating electricity from it. But he was kind of wrong. Remember we talked about wet sand? Possibly that waterway was built specifically for making wet sand and lifting the stones upward.
Nikola Tesla's Theory
Even if it sounds unbelievable, Nikola Tesla also had a theory about the pyramids. He believed the pyramids had some other purpose. From that thought, he made a small pyramid out of paper and wire and placed it in the path of charged particles. It was seen that the structure was glowing. According to Tesla, the pyramids were positioned to collect energy from Earth's magnetic field.
This theory could actually be true. Because think about it — you are a pharaoh and the tomb built for you glows throughout the night. It is pointed toward Orion, aligned with Earth's axis. What could be grander than this?
Recent Discoveries and Ongoing Mysteries
The 2025 Underground Structures Claim
And in recent times, the biggest hype around pyramids arose in 2025, when Professor Corrado Malanga's team found eight huge cylindrical structures beneath the Giza pyramid using scanners. Their discovery sent shockwaves through the scientific community. Some said underground city, some said Egypt's legendary Hall of Records — and many other things.
More than a year has passed amid much debate for and against it. Conspiracy theorists would build an entire country beneath the pyramids if they could. But even after all this time, no review of this research journal has come. Professor Corrado Malanga's team has not been able to provide any data beyond that initial scan. In the meantime, radar expert Professor Lawrence Conrads has outright said that this data is fake. Because the technology they used supposedly cannot scan to such depths underground.
The Big Void
But beyond this, there are some unanswered questions about the pyramids. In 2017, the Scan Pyramids project used muography technology and found that inside the Giza pyramid there are several cavities about 100 feet long, which we have still found no way to enter. This has been named "The Big Void."
Temperature Anomalies and Hidden Corridors
In 2022, another research revealed that there is quite a difference in temperature beneath the Khafre Pyramid — some places hotter, some cooler. It is believed these could be unexplored corridor systems. In 2025, satellite radar data claimed that beneath the Giza pyramids there may be many interconnected structures — which were perhaps used as the base of the pyramids during construction.
The Unanswered Question
And the most astonishing thing — we've talked about organized labor, we've talked about technology. We know writing with a pen started from Egypt. Despite all of this, we have found no plans, no documents of these pyramids. Except for Inspector Merer's diary, no books or writings from the time of their construction have come to us so far.
So, the question of why — nearly four and a half thousand years ago and more — people built such massive structures and put in such immense labor, still remains.
Of course, perhaps they wanted to build something for the world that would mesmerize us, that would constantly amaze us. Perhaps in the days ahead we will solve all the mysteries surrounding the pyramids, we will come to know everything. But until then — let the only surviving Wonder of the Ancient World mesmerize us. Let it remain in mystery, as mystery.
