NARRATOR: Cairo, Egypt, April 2018-- during his first visit to Egypt in nearly two decades, ancient astronaut theorist Giorgio Tsoukalos is eager to find out about a recent discovery concerning a possible hidden chamber located deep inside the walls of the Great Pyramid of Giza. This way. NARRATOR: With him are egyptologist Ramy Romany and archaeoastronomer Dr Giulio Magli.
They are making their way to what is called, the Grand Gallery, which can only be reached after walking up a 200-foot long passageway. Directly above their heads is the area where an international team of scientists believe they may have located an enormous hidden chamber, more than 100-feet long. So this is it, the Grand Gallery.
If you look at this and you think, they made this more than 4,000 years ago. They actually built this. This is incredible.
From here to the ceiling is about 10 meters high. And it goes about 50 meters in, which is 150 feet deep. I mean, that just gives you an idea of how huge this place is.
And it's perfect. The blocks, they fit together, and no mortar was used. And you can't even put a money bill in between the fittings.
And this is what type of stone that we're looking at in here. Unlike the rest of the pyramid, this is red granite. GIORGIO TSOUKALOS: Red granite, right.
RAMY ROMANY: Red granite doesn't come from a local quarry like the limestone does. GIULIO MAGLI: It comes from Aswan. Aswan.
So that's 1,000 kilometers away. RAMY ROMANY: 1,000 kilometers away. GIORGIO TSOUKALOS: 600 miles.
So you think the void is right on top of our heads here? And how big is it in relation to where we're standing? OK, wow.
NARRATOR: The news of a possible fourth chamber within the Great Pyramid has become a source of great controversy inside the archaeological community. They have long held the belief that pyramids were essentially built as burial vaults, each possessing no more than three chambers. Archaeologists and egyptologists claim that they were tombs for the pharaohs.
And yet no Egyptian pharaoh was ever found in a pyramid in Egypt. [music playing] We have found the mummies of many Egyptian pharaohs. But they're found in vaults, deep underground at the Valley of the Kings in Luxor, hundreds of miles away from the pyramids.
The pyramids, they have no real explanation of what their purpose was. When we found this pyramid, there was no mummy. There were no treasures, no nothing, no hieroglyphics, nothing.
What if all this that we're looking at is a decoy? You just raised a very interesting point. The fact that we've come so far into this chamber, and the entire way, not a single hieroglyphic.
Because throughout the rest of Egypt, the walls are plastered with inscriptions, telling the story of how it was built and by whom and when. Yet here, so far, complete anonymity. Absolutely.
NARRATOR: Because the walls inside the Great Pyramid contain no hieroglyphics and there is no evidence that the colossal structure was ever used as a tomb or temple, there has been increasing speculation as to its original purpose. One theory, held by numerous scientists and archaeo-engineers, is that the pyramid and others like it may have been built as one in an enormous network of power plants. [music playing] Christopher Dunn's theories indicate that some of these pyramids had chemicals mixed in them.
And in fact, studies of his working devices have shown that this probably would work. [music playing] CHRISTOPHER DUNN: Pyramids were actually geomechanical devices. In other words, they were attached to the earth.
They were tuned to vibrate with the frequencies of the earth. And they converted the energies of the earth into electromagnetic energy. The best example of this is in the Great Pyramid.
It's probably the most precise structure on the planet. NARRATOR: According to Christopher Dunn's theory, the process of generating energy began with drawing water from the nearby Nile River to the base of the Great Pyramid. Right in front of the door of the-- entrance door of the great pyramid, there used to be a well shaft, which was documented in 1857.
And so the water would just gravity feed down into, basically, a moat around the Great Pyramid and then go down the entrance shaft, down into the ground. SPEAKER: The water was used in the subterranean chamber. It is a water pump.
I believe the water was used to cause a compression wave and cause the pyramid to resonate. CHRISTOPHER DUNN: So in the queen's chamber, two chemicals were introduced-- hydrated zinc through the northern shell and a dilute hydrochloric acid through the southern shell. This vessel represents the queen's chamber.
[music playing] Into the tubes, we're going to pour hydrated zinc and then hydrochloric acid. When you bring these two liquids together, a chemical reaction occurs. And a product of that chemical reaction is hydrogen.
And you can see the vapor, the hydrogen escaping through the chimney. And there you have the reaction. NARRATOR: Adding credibility to Chris Dunn's remarkable theory is the fact that traces of both zinc and hydrochloric acid have recently been found in the shafts leading to the so-called queen's chamber.
But if the pyramid was really designed as a gigantic power plant, how was that power applied? CHRISTOPHER DUNN: We can come up with all kinds of devices to power with that kind of energy, from simple domestic appliances to highly advanced spacecraft. NARRATOR: Might the Great Pyramid of Giza have been designed as part of an enormous network of ancient power plants, not 4,000 years ago but much, much earlier?
