Luyện nói tiếng Anh bằng Shadowing qua video: What’s Really Hidden Beneath the Pyramids of Giza? | The UnXplained

An ancient desert covered in hundreds of pyramids.

A massive earthen hill hiding a sacred and deadly spring.

And a controversial discovery hidden deep beneath the Alaskan wilderness.

For thousands of years, civilizations around the world built monumental structures made of stone

and brick that we call pyramids we call pyramids.

In Africa, Asia, Europe and the Americas,

ancient engineers created surprisingly similar constructions while having no knowledge of what other cultures were crafting.

How's this possible?

Were pyramids meant to be tombs or temples?

Or was there a greater purpose to some of these incredible works?

Well, that is what we'll try and find out.

Cairo, Egypt.

Towering over the limestone desert sands of the Giza Plateau stands the oldest of the seven wonders of the ancient world.

It is called the Great Pyramid of Giza.

Built in 2600 BC, the monolith is flanked by two smaller but equally colossal pyramid structures.

The Giza complex is a monumental achievement in ancient engineering and a marvel that has confounded scientists and researchers for centuries.

The Great Pyramid on the Giza Plateau is an astonishing construction.

There's 2.3 million blocks of limestone in the structure itself.

I mean, it takes an hour to walk around it, at least.

But it's also the fact that you have these giant platforms, megalithic blocks, perfectly created.

Inevitably, people want to ask how on earth a civilization thousands of years ago could have achieved this.

The right angles at the corner are almost absolutely bang on 90 degree angles.

The lengths of the sides are almost perfectly equal on all four of them.

They are closer to perfect than would be required for modern buildings.

It is an unparalleled achievement.

It's possible we'll never completely understand how the great pyramids were constructed with such remarkable precision.

But perhaps an even greater mystery is, why were they built in the first place?

The great pyramids of Giza are one of the great untold mysteries.

We're not quite sure how they were used, they were used.

But what we see today in the Pyramids of Giza are the sort of the bones of these buildings.

In Egyptian antiquity, Pyramids of Giza were encased in white limestone and presumably polished.

And so during the daytime, you would have seen these sort of white mirror-like surfaces.

What we're missing is a limestone covering and a golden top piece.

But the pyramids themselves don't have any particular explanation of why they were built or the symbolic purposes of it.

So part of the mystery is trying to figure out what is this thing?

Ultimately, there are more questions than answers when it comes to the pyramids on the Giza Plateau.

Some of them were used as tombs, but in my own opinion, that was a secondary function for many of them.

If the Great Pyramids weren't strictly used as tombs, as most mainstream Egyptologists maintain,

then what was their fundamental purpose?

The Egyptian Museum, Cairo, Egypt.

This massive building houses the largest collection of ancient Egyptian antiquities in the world.

Among the many treasures is a 3,800-year-old capstone from the pyramid of King Amenemhat III,

that some believe is connected to a mythical Egyptian object known as the Benben stone.

In the Cairo Museum, there is a pyramidion, which is made of a beautiful black basaltic type of rock from a pyramid.

That seems to be our best representation of what the Ben Ben stone was like, according to the ancient Egyptians.

That Ben Ben stone goes back to maybe 1850 or so BC.

So it's not the original one, but it represents what the original one was.

In ancient dynastic Egypt, there was a literal Benben stone.

That Benben stone has long been lost, unfortunately.

But some people have suggested maybe it was a meteorite that was pyramidally shaped by the ancient Egyptians.

It has sacred power.

While some believe the original Ben Ben stone was a meteorite, legends from ancient Egypt suggest it was a place of divine creation.

Egyptian mythology says that there were once just waters of chaos,

and then what grew through the waters of chaos was an island in the shape of a pyramid called the Ben Ben.

And it was here that the sun god Ra came to Earth and began life.

When they built the first pyramids, it seems that they were trying to recreate this Benben stone.

Interestingly, on top of many of the early pyramids, they actually had a recreation of the Benben stone on top of them,

a capstone, which was covered in electrum, which is a alloy of gold and silver, show that it shone in the sunlight.

All this showing that the pyramids are connected with the sun and gaining the power of the sun, or the sun god, Ra.

There's also these ideas that these Ben Ben stones were actually some kind of power collector.

Some people suggest they attract lightning.

There's different ideas about this, but it has been suggested in Egyptian tradition

that placing such a thing on top of a pyramid would almost be like connecting with the solar energy,

but also connecting with the cosmos.

Could the great pyramids have been some type of ancient power plants?

Perhaps clues can be found in the 21st century research that presents an extraordinary claim.

March 2025.

After analyzing satellite data, a team of Italian scientists make an extraordinary, yet controversial, announcement.

They claim to have identified a vast underground complex extending beneath the great pyramids of Giza.

One of the most fascinating discoveries discoveries that could potentially rewrite the history of Egypt and the world

are the discoveries that have been made beneath the pyramids on the Giza plateau.

Now, this is the work of the CAFRA research project, using satellites to actually penetrate into the ground with a mix of other technologies.

What they claim to have found is a series of shafts going over 600 metres down into the ground,

Then there's these giant square chambers and many other chambers, many other systems across the entire Giza plateau,

underneath all the pyramids and even underneath the Sphinx as well.

They're now claiming that there's a whole veritable underground city beneath Giza.

But then the question becomes, why did they do this?

And we can't obviously tell exactly what's down there until we fully investigate,

But it would seem that this influenced the positioning of the pyramids actually on the surface.

Could there be an entire city hiding beneath the great pyramids of Giza?

Only time will tell.

And while Egypt's colossal creations are awe-inspiring,

these remarkable structures represent a mere fraction of all the enigmatic pyramids found on nearly every continent on Earth.

Pyramids have captured our imagination just because of their sheer monumentality.

The biggest of them are among the biggest buildings human beings have ever built.

They are monumental, serious achievements.

Very, very beautiful.

That to me is absolutely awe-inspiring.

Pyramids were built by different cultures at different times, with the earliest pyramids probably going back to the beginning of the third millennium BC.

But I suppose the bigger question is why build pyramids?

Was there some reason different cultures have done this all over the world for many thousands of years?

We need to know why.

Northern Sudan.

Among the ever-shifting sands of the Nile Valley stands a remarkable achievement.

Hundreds of ancient pyramids that stretch about 150 miles across the desert.

These UNESCO World Heritage Sites contain what are known as the Nubian Pyramids.

What often surprises people is

that there are more pyramids in Sudan Sudan than there are in Egypt with more than 200 known structures.

Most of them are clustered around El-Kourou, Nuri, and Meroe.

100

A few are found at Jebel Barkal near the sacred mountain.

101

These pyramids functioned as tombs for the dead, but also a statement of authority and continuity in ancient Sudan.

102

When there was an offering chapel placed at the front of these pyramids, they had a distinct Nubian character to them.

103

What's really interesting about them is the fact that they're like solid stone constructions.

104

They don't have any chambers within them, but they have chambers deep underneath them where the kings

105

and queens are said to have been buried with staircases around the side of them leading down into them.

106

Construction on the Nubian pyramids began around 750 BC and continued for about 1100 years.

107

These steep structures range from 20 to 100 feet tall, and are made from a combination of sandstone, rubble, and mud bricks.

108

And the mysterious lost civilization that made them is known as the Kingdom of Kush.

109

Kush was a kingdom to the south of Egypt.

110

They seem to have been very much influenced by the Egyptians.

111

It flourished from around the 8th century BC down to the 3rd or 4th century AD.

112

In that very early time, 8th century into the 7th century, Kush became powerful enough to invade Egypt

113

and take it over over a Kushite king took control of Egypt

114

and made himself recognized as the Pharaoh he was able to maintain control of Egypt

115

and in fact his successors were as well

116

and this line of Nubian kings came to rule Egypt as the Egyptian 25th dynasty

117

and they remained in control for the best part of a century

118

but we don't understand in all the details exactly how this happened as As powerful as the kingdom of Kush once was, much of their story remains unknown,

119

because scholars have yet to decipher their puzzling system of writing, known as Meroitic.

120

But some believe the key to understanding this mysterious kingdom could still be hiding beneath one of its pyramids.

121

Nuri, Sudan, 2018.

122

A team of scientists begin an unprecedented investigation of the ancient necropolis that consists of around 20 Nubian pyramids,

123

including the pyramid of King Nastasen, the last Kushite king to be buried here in 315 BC.

124

King Nastasen reigned during a very interesting time of political transition.

125

The fact that he was the last to be buried at Nuri, and then the Kushite capital was moved deeper in the desert,

126

that makes his tomb an interesting capsule of maybe what was happening during this time.

127

The Nuri Archaeological Expedition began work in 2018 to start excavations at this massive 170-acre site.

128

We had a possibility that there was an intact tomb for Nastasin,

129

and so I was brought on to work with the skeletal remains that may be found on site.

130

Over the centuries, rising groundwater has left the three burial chambers of King Nastasin's pyramid completely flooded.

131

To access the tomb, an experienced dive team was needed to explore the pristine and unpredictable environment.

132

The tomb of Nastasin has remained untouched from looters due to it being flooded.

133

The water has acted like a protector for the tomb.

134

No one's going to be able to swim and hold their breath

135

and swim all the way into chamber three and retrieve these objects.

136

So it's kept them safe over the last 2,500 years.

137

What wonders could the flooded pyramid of King Nostasen still hide below?

138

In 2019, Justin Schneider became one of the first people in thousands of years to enter its unknown depths.

139

The water in the front of the tomb is a brownish sand color from all of the outside, sediment and all the rock falling into it.

140

You come in through chamber one, which is a long hallway.

141

Water goes all the way to the top.

142

Once you go into chamber two, you can actually put your face out of the water.

143

You can see inside this tube.

144

It was a little scary to see how much of the ceiling had collapsed.

145

That chamber was pretty chaotic, but you could still make out the size and shape of that chamber.

146

And we were finding shabtis, these small figures that have hieroglyphics on them.

147

These little shabti figurines, they're these tiny doll-like carved statues.

148

They are five to six inches.

149

They're made of clay.

150

They're beautiful.

151

They're ornate.

152

Just touching the stuff, to touch history is incredible.

153

While the team discovered a number of small artifacts, the real prize was believed to be inside the pyramid's third and final chamber.

154

Within the third burial chamber, while it was difficult to see,

155

there was a large rectangular slab that was about in the middle of the chamber

156

that we would estimate to be either a sarcophagus or a burial bed.

157

You're swimming through this water, this murkiness, and then finally getting to chamber three, the burial chamber.

158

It was breathtaking to see what you know is a king's burial.

159

There is a pharaoh, there is a king buried inside of this.

160

It's a time capsule that's just waiting to be opened.

161

But we just can't blatantly go in there and start digging.

162

We have to figure out how to take that out in order to be preserved.

163

Unfortunately, before the team could enact a plan to safely open King Nastasin's sarcophagus, civil war broke out in Sudan,

164

and all excavations have since been halted.

165

It is my hope that the political situation can be resolved.

166

The Nubian pyramids are tantalizing clues to understand a past in the Nile Valley

167

that has typically been overlooked when studying the ancient world.

168

There is so much more to be discovered.

169

It's fascinating to imagine the kingdom of Kush covered in more than 200 pyramids.

170

But halfway across the globe, there is a massive structure that stands alone.

171

It's the largest pyramid in the world.

172

And for centuries, it was hidden in plain sight.

173

Cholula, Mexico.

174

In the shadow of an active volcano stands a massive, grass-covered hill, crowned by an impressive 16th century Spanish church

175

and buried below hide something few would expect the Great Pyramid

176

of Cholula this is an interesting one the Pyramid of Cholula its name in Nahuatl means man-made mountain

177

so there's already an acknowledgement that this thing is big and this thing is really It is in fact, contrary to many people's expectations,

178

the largest pyramid in the world.

179

It's not the tallest.

180

The Great Pyramid of Giza is in fact taller, but by volume.

181

The Pyramid of Cholula is the largest pyramid that humans have ever constructed.

182

Scientific archaeology really began in the late 1920s 1920s with the Proyecto Cholula,

183

a project that was directed by Ignacio Marquina.

184

And Marquina explored the pyramid through eight kilometers of tunnels that the archaeologists dug.

185

These tunnels uncovered murals, and archaeologists discovered that there were actually multiple construction phases.

186

So the pyramid is a sort of a layer cake with platforms that come out from the sides.

187

largely unexcavated.

188

Today, walking through the tunnels, you absolutely get a sense of the weight of the pyramid above you because it is massive.

189

The pyramid started out as a smaller pyramid.

190

Later on, that got covered over by just sort of putting a new one on top of it.

191

And then that got covered over.

192

There were like eight or nine layers to this

193

and over time it got bigger and and then when the Aztecs took over, they had no idea how it got this big,

194

and it was just as much a mystery to the Aztecs as it was to us.

195

While it's believed the pyramid was first constructed about 200 B.C., and later built upon by Mesoamerican cultures like the Olmecs and the Toltecs,

196

local legends describe the original builders as monumental in stature.

197

One of the most fascinating traditions relating to the pyramid of Cholula is that of the Quenemetzin giants.

198

This was this very ancient era going back potentially thousands of years.

199

These giants, who were said to be up to 12 feet tall, constructed the Cholula pyramid, because it is so vast,

200

so big, no one could imagine how any humans could have constructed it themselves.

201

While it's intriguing to think that giants built the first iteration of the Great Pyramid of Cholula, the legend itself suggests that even centuries ago,

202

the structure was not only hard to explain, but also a place of profound ancient reverence.

203

This has been a temple at every stage, so I think one of the things we see here is a recognition of the holiness or the sanctity of this place.

204

That a temple followed by another temple, followed by another temple being topped with a church.

205

In Cholula, we see this unintentional collaborative process that builds upon the sanctity of this unbelievably holy place.

206

Cholula's importance to many Mesoamerican cultures has led to another fundamental mystery.

207

Why was the largest pyramid ever constructed hidden under piles of dirt?

208

Some people suggest that it wasn't necessarily just abandoned, but the Aztecs and the indigenous people,

209

Knowing that the Spanish were coming to conquer them, they wanted to cover it up.

210

So there's some suggestions that they may have tried to plant plants on it, hide it, disguise it.

211

By the time the Spanish came, apparently they thought it was a natural hill.

212

They did not recognize it as a pyramid.

213

Was the Great Pyramid of Cholula deliberately disguised to hide it from Spanish invaders?

214

And if so, what were its guardians compelled to protect?

215

According to legend, right at the base of the Cholula Great Pyramid, there was a natural spring,

216

and it is seen as the waters of life emerging from the place of first creation.

217

It was said that Cholula was built Shortly after the time of a great flood,

218

a deluge that had ended a previous world age.

219

So did this really happen?

220

Is this a memory of some of the first people to create the earliest stages of this pyramid?

221

Very possibly.

222

Could the Great Pyramid of Choluda be built atop a powerful sacred spring?

223

It's a belief that was still in existence in 1519,

224

when Spanish invaders led by Hernan Cortes first reached the ancient city of Cholula.

225

One of the myths from the time of the conquest was

226

that the indigenous allies

227

that were accompanying Cortes on the attack on Cholula were afraid of entering the city

228

because they believed that anybody attacking Cholula Cholula would be washed away when the pyramid burst forth with earthly waters.

229

But we don't know.

230

Chalk it up to a mystery.

231

We don't know who built it.

232

We don't know the details of their mythology or their cosmology.

233

But we see this recognition of sacredness in this location.

234

It's significant that what was built here at every stage was a temple.

235

It's common knowledge that the Cholula pyramid was built to be a sacred religious site

236

and it successfully served that purpose for over a thousand years.

237

But the same cannot be said for a collection of rectangular

238

pyramid-shaped structures found in the remote Canary Islands whose very existence has baffled scientists for decades.

239

Tenerife, the Canary Islands.

240

More than 200 miles off the northwest coast of Africa, this remote island rises from the Atlantic Ocean.

241

And here stands six enigmatic structures made of stacked volcanic stone known as the Steppe Pyramids of Guimar.

242

These are pyramids that there's a lot of controversy about.

243

People have suggested that these are very ancient pyramids ancient pyramids, a very ancient site.

244

So there's been a lot of mythology and speculation about the modern legends that have developed about these pyramids.

245

But these pyramids may only go back to the 19th century.

246

They may be nothing more than the result of people clearing their fields

247

and stacking them up and making pyramids out of them.

248

So just how old are these mysterious structures?

249

Well, some believe the most compelling clue could be their connection to the summer solstice, the longest day of the year.

250

These pyramids are perfectly aligned towards sunset at the time of the summer solstice.

251

And this was actually confirmed by archaeo astronomers under the leadership of Juan Belmonte,

252

who actually lives on the Canary Islands.

253

So this is a very special phenomena, and it could be behind why these pyramids were constructed in the first place.

254

Were the Guimar pyramids built to mark the summer solstice?

255

If so, the theory that they were simply stacked by 19th century farmers after clearing their fields seems too simple an explanation.

256

And more intriguingly, some claim the pyramids on Tenerife Tenerife share striking similarities to other pyramids around the world.

257

There are other alignments to stars, exactly as we find in the Egyptian pyramids,

258

and we also find in the pyramids of Central America.

259

The native people who lived on Tenerife before the Spanish arrived

260

in the 1500s had seemingly been living in isolation for thousands of years.

261

How could they possibly be building the same kind of things as people either side of the Atlantic, unless there was some connection between them?

262

Are the pyramids of Guimar connected to other pyramids around the world?

263

Well, according to one world-famous explorer, the link could be more significant than we've imagined.

264

Thor Heyerdahl was a Norwegian explorer who was most famous for his Contiki voyage,

265

which aimed to show that people could use quite simple rafts to conduct long-distance sea travel.

266

Heardal travelled to Tenerife in the 1990s and was particularly intrigued by the idea

267

that ancient navigators would have had a very good understanding of the stars to help them navigate,

268

and that as they travel, ideas would be spread around geographically.

269

So mapping that theory onto the pyramids of Guimar, Heardall thought, well, if there are pyramids here in the Canary Islands,

270

which is between Europe, Africa and the Atlantic Ocean,

271

why can't there have been this sort of cross-pollination of ideas around the world?

272

Did pyramid builders share their knowledge throughout the ancient world across vast oceans?

273

It's a fascinating theory that may suggest

274

that the pyramids of Guamarr really were constructed in antiquity by the original inhabitants of the Canary Islands,

275

a now extinct culture known as the Guanche.

276

The Guanche are indigenous people to the Canary Islands.

277

They're very mysterious on many levels.

278

Modern scholarship suggests that they actually are an offshoot from North Africa that got to the islands in the first millennium BCE,

279

living there until the Spanish ultimately conquered the Canary Islands in the 15th century.

280

The Guanche had a lot of what appears to have been advanced knowledge in terms of mummification

281

and the rituals they carried out.

282

They lived in caves and stone huts.

283

But there's this whole modern,

284

should we say, hypotheses and legends and suggestions that somehow they were descendants of Atlantis,

285

a legendary civilization that was decimated by natural events.

286

Bottom line is, the Guanshe are a real mystery.

287

They're something that needs more study.

288

Absolutely fascinating.

289

Could the early inhabitants of the Canary Islands have some connection to the mythical island of Atlantis?

290

It's fantastic to consider.

291

But more importantly, were the Guanshe people once part of a network responsible for the proliferation of pyramids around the world?

292

The builders of these pyramids on Tenerife were pretty sophisticated.

293

They were building these quite elaborate black stone constructions.

294

They were aligning them to specific movements of the sun and the stars as well.

295

It does appear that there was a common architectural language being spread across the world in ancient times.

296

We find very similar pyramid styles in all these different places, often step pyramids.

297

There was almost like an ancient code being embedded within these permanent structures in all these different parts of the world.

298

So this gets into the argument of, argument of was there knowledge being passed around?

299

We don't know.

300

There's just a lot of mysteries about pyramids when it comes right down to it.

301

Could the astrological alignments found at the Canary Island Structures be evidence of a universal pyramid code spread around the world?

302

Perhaps time will tell, which may also be the case for a controversial claim

303

that a powerful pyramid lies hundreds of feet below the Alaskan tundra.

304

Alaska.

305

With over 57 million acres of designated wilderness, which is more than all other U.S states combined,

306

and with civilization found in less than one percent of its total land mass,

307

there have been and many claims as to what's hiding in this remote frontier.

308

But perhaps one of the strangest tales revolves around an alleged dark pyramid, obscured beneath Alaska's frozen wasteland.

309

The dark pyramid is a presumed pyramid that is hidden under the ice and tundra of remote areas of Alaska.

310

This pyramid is near Mount Denali in the heart of what's known as the Alaska Triangle.

311

The Alaska Triangle is a very anomalous area,

312

which stretches from Juneau in the south to Anchorage in the middle and Yukiavik at the top, formerly Barrow.

313

And it's much like its namesake, the Bermuda Triangle, in which there's a lot of strange activity that happens in this area,

314

with the dark pyramid right at the heart of it.

315

If a pyramid is hiding beneath the ice in one of the most remote regions of Alaska.

316

How would we even know about it in the first place?

317

Well, according to the story,

318

it was detected in 1992 when China was testing weapons of mass destruction beneath a dry lake bed known as Lutmoor.

319

In 1992, the Chinese government initiated underground nuclear testing.

320

The United States knew about this.

321

Our geologists set up a bunch of seismic equipment to be able to detect the shock waves from this explosion.

322

And when that explosion occurred and the seismic equipment was going off,

323

they discovered this strange pyramidal shape near Mount Denali in Alaska.

324

To this day, no public record has confirmed the discovery of a buried pyramid beneath Alaska.

325

But some are convinced that the lack of evidence is purely intentional,

326

because it's said that when news of the dark pyramid was released, it was immediately covered up.

327

It was broadcast on the local news, Anchorage Channel 13, that this had been discovered.

328

And there was a young service member, Doug Butchler, in the Army who saw this particular broadcast.

329

And he was so fascinated by this.

330

Doug Mutchler worked in counterintelligence for the Army in Fort Richardson in Anchorage.

331

That particular night, there were 40 guys, and they're watching Channel 13,

332

and it shows a pyramid structure underneath the ground in Alaska.

333

So he approaches the general manager at Channel 13.

334

The general manager said, I don't know what you're talking about.

335

And Doug said he started arguing with the general manager.

336

I was with 39 other guys, 40 of us.

337

We watched this.

338

And the general manager said, well, you are mistaken.

339

Doug turns around to leave, and coming around a corner is a man who took hold of his arm and says, I know what you're talking about.

340

Yes, we have that film, but we have been told that we are not to broadcast it or talk about it anymore.

341

Was the story of the Dark Pyramid deliberately buried?

342

And if so, why?

343

For some, the answer is simple.

344

The Dark Pyramid isn't really a structure at all,

345

but a 550-foot-tall, top-secret machine.

346

There are a few different theories about the Dark Pyramid.

347

One is that it was some sort of ancient power plant that has been hidden under the surface of Alaska.

348

When we look at the Great Pyramid of Giza, one of these suggested ideas of what it was was a possible ancient power plant.

349

Now the Dark Pyramid is supposed to be taller than the Great Pyramid of Giza.

350

So how much more energy than the Great Pyramid of Kiza could this dark pyramid be harnessing?

351

Why would a 550-foot solid black pyramid be underground?

352

What is it doing in the backcountry of Alaska and how long has it been there?

353

I think there's no question the government of the United States didn't want anybody to know anything about this dark pyramid.

354

Did they know about the pyramid before the 1992 Lop-Nor bomb test?

355

Oh, I think so.

356

Mars, 1972.

357

As NASA's Mariner 9 spacecraft photographs the red planet,

358

it captures something unusual in a region called Elysium.

359

Formations that appear at least from orbit to resemble pyramids.

360

One of the images that they took in the Elysium area of Mars actually showed what appeared to be three-sided pyramids.

361

They were noticed by a scientist by the name of Mac Gibson.

362

He actually had a science paper published in Icarus Journal titled, Pyramidal Structures on Mars.

363

So early on there was a lot of scientific investigation Real scientists were looking at Mars saying, oh, possibly there's structures here, structures that looked artificial.

364

Could there actually be artificial pyramids on Mars?

365

Well, it sounds far-fetched.

366

In 1976, NASA's Viking 1 orbiter photographed yet another strange formation that researchers named the D&M Pyramid.

367

The D&M Pyramid looks like a five-side pyramid, pyramid, which is unusual unto itself.

368

Other pyramids in Martian photographs look like they have three sides,

369

but people made claims these must be artificial structures that came from some, you know, civilization on Mars.

370

And I'm not opposed to the possibility of there being extraterrestrial sophisticated civilizations,

371

but we have to be very careful when we think we see artificial pyramids.

372

Nature also forms pyramids and pyramidal type structures.

373

You can have symmetry in nature.

374

As a geologist, I see symmetry all the time.

375

What are some of the most symmetrical things?

376

A pyramid.

377

Without visiting the red planet ourselves for a closer look,

378

it's impossible to know whether the alleged pyramids on Mars are just natural formations or artificial constructions.

379

But with so many mysterious pyramids that continue to fascinate us right here on Earth,

380

perhaps it's simply part of human nature to become enamored with these iconic, awe-inspiring structures.

381

Humans have always wanted to build the biggest thing that lasts for the longest.

382

So if you're an ancient culture, this is a pyramid because you have the stable structure which allows you to build quite high.

383

I therefore think that the fact you have pyramids in Mesoamerica, in the Canary Islands, and in Egypt,

384

is just a reflection of how different cultures come up with similar solutions to similar problems.

385

How do we build high?

386

How do we build big?

387

A pyramid is your answer.

388

Each of these things that we call pyramids has a code has a code.

389

Whether we understand that code or not, that's part of what the scholarship is trying to sort of figure out.

390

How were these places used?

391

And that's the stuff that scholarship is made of.

392

But whether we know the code or not, that's another question.

393

Could pyramids really exist on other planets? Who knows?

394

For now, it's the remarkable structures we have here on Earth

395

that continue to captivate us and challenge our understanding of human history.

396

The Giza Plateau may be the best-known pyramid complex,

397

but it's only one example of this extraordinary engineering found all around the world.

398

Will we ever know how and why some pyramids were built?

399

The secrets surrounding these mysterious structures are innumerable and may forever remain unexplained.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
