1
You'll never see any of these gargantuan projects completed in person. But soon,
2
you'll know exactly what it would feel like to witness the launch of every multi -generational super construction project ever conceived.
3
From the realistic to the absolutely insane.
4
What would it be like to stand on these megastructures?
5
Could we ever realistically build any of these?
6
And could humanity ever finish a project that outlives everyone who starts it?
7
Now, what is a megastructure?
8
And do we have any already underway?
9
Well, simply put, a megastructure is just an extremely large man -made structure, like a building.
10
It's a project that, if completed, would overshadow any other object completed before it.
11
Think of what a skyscraper would look like to a caveman, and then multiply that by a million.
12
And while you're thinking of skyscrapers, imagine the biggest one you can.
13
The Burj Khalifa, at nearly one kilometer tall, is a structure that took six years to complete.
14
That's pretty impressive, right?
15
Well, lay it on its side and extend that out 170 times.
16
Now you've got a modern -day megastructure, and one that's actually being worked on today.
17
Ever heard of The Line?
18
That's its name, not something I came up with.
19
It's a 170 -kilometer -long city drawn ruler straight across the desert of northwestern Saudi Arabia.
20
When it's finished, it will house 9 million people living behind a mirrored wall
21
that rises half a kilometer above the shifting dunes.
22
The initial budget for this project was a jaw -dropping $500 billion U .S.
23
The line's design uses state -of -the -art construction techniques and environmentally sustainable practices.
24
It was designed to be a vision of what the future holds, a different concept of human livability.
25
All your daily needs are within a five -minute walk.
26
For longer trips, there's a high -speed rail system that transports you underground.
27
It will only take 20 minutes to go from one end to the other of this line.
28
Construction kicked off with thousands of workers and hundreds of machines.
29
And soon, we started to see a city emerging from the desert.
30
But work was suddenly suspended in September of 2024,
31
even though they'd only completed a tiny 2 .4 -kilometer section of the foundation.
32
Remember, the plan was 170 kilometers.
33
The project had already burned through 8 billion dollars.
34
Everything about the line is technologically feasible.
35
Nothing was missing from an engineering standpoint.
36
It could easily be the city of the future, so why the sudden stoppage?
37
A leaked audit estimated that the project was going to take 50 years longer than originally claimed,
38
and the actual cost would be $8 .8 trillion dollars.
39
That's roughly 1 ,600 times over budget.
40
Megastructure meet financial reality.
41
Fund managers got spooked and slammed on the brakes.
42
If this kind of mismanagement can kill a decades -long project like
43
The Line, well, megastructures in space take way longer.
44
How can a thousand -year project ever hope to be completed.
45
I mean, the ISS was built in 13 years with the cooperation of 15 countries,
46
but the projects we're talking about will take so long to complete
47
that multiple generations will live and die before construction is complete.
48
Is building them even possible?
49
In all of human history, do we have any examples of humans being coordinated and motivated enough to actually build something like a megastructure?
50
Now, you might already be thinking of an example of a megastructure built, like the Great Pyramids.
51
Mega monuments of towering stone built to carry the pharaohs into the afterlife, which surely took an eternity to build.
52
Well, written accounts from around
53
that time suggest it took about 20 years to build the Great Pyramid of Khufu not exactly the multiple lifetimes
54
we're looking for.
55
However, there is one interesting example of a building whose construction outlasted its architects and master builders by hundreds of years.
56
Though not necessarily intentionally.
57
The Cologne Cathedral.
58
It was the megastructure of its time.
59
Started in 1248, the drawings laid out the plans for the world's largest Gothic cathedral.
60
The design for the nave reached a staggering height of 43 .5 meters, that's 143 feet.
61
On the outside, the tower facade would be 157 meters, that's over 500 feet high.
62
The average person in 13th century Europe would have looked at it the way we look at a space shuttle launch,
63
or even a future moon base under construction.
64
And if you think about the relatively primitive construction technology they had at the time, it's nothing short of a miracle.
65
All the stone was quarried and cut by hand.
66
Only simple machines were available to help.
67
Ropes and pulley systems were used to hoist heavy stone blocks into place tens of meters into the air.
68
Remember that in 1248, the average lifespan of an artisan was only 40 or 50 years.
69
Three generations of master builders supervised the first phase, which lasted 200 years.
70
Generations of carpenters and stonemasons worked on it, passing down their skills and their jobs to their children and their children's children.
71
But then things changed.
72
Pilgrims stopped visiting.
73
Finances dried up and the work stopped.
74
The cathedral stood half -completed with an abandoned construction crane hanging from its south tower for 375 years.
75
It looked like it might never be completed, but new money was raised and luckily the original plans were found.
76
When construction resumed in 1823,
77
it was a testament to their genius that the engineering in the original medieval era plans were still sound.
78
And work continued for another 57 years.
79
Now when it was finally completed in 1880, 623 years after the first stone was laid,
80
the Cologne Cathedral was the world's tallest building.
81
And it's still considered to be a marvel of engineering and technological innovation.
82
And in some ways, it's never really complete.
83
Even today, it takes over 100 craftspeople to maintain it.
84
So yeah, I guess people can actually build something that takes multiple generations.
85
So what could people actually achieve with today's technology?
86
In the 1970s, physicist Gerard O 'Neill challenged the assumption that
87
Earth is the best place for humanity.
88
He thought that, frankly, we can do better.
89
And he came up with an idea to prove it.
90
But it was going to take a megastructure.
91
It was a simple solution, but on a grand scale.
92
Two massive counter -rotating cylinders turning in space at one rotation every two minutes.
93
The centrifugal force of the tube's rotation draws everything inside to the surface and replicates
94
Earth's gravity at a steady 1G.
95
Three strips of land contain cities, and three strips of windows let in sunlight.
96
A mirrored shutter system creates a light cycle to mimic
97
Earth's day and night.
98
The two structures are large enough to hold 7 million people.
99
Looking up from anywhere inside of its surface,
100
the ponds, gardens, and buildings of your neighbors hanging upside down above you are 8 kilometers away.
101
And looking down the full 32 kilometers of its length, the haze of the atmosphere would blur the tube's end.
102
Human -powered flight would become a popular pastime because as you left the interior surface,
103
the effects of the centrifugal force would fall away.
104
The closer to the center you propelled yourself, the lighter you'd become.
105
And at the very center of the tube, you'd become weightless.
106
Now, O 'Neill didn't invent the basic concept here.
107
He wasn't the first to design using the idea of centrifugal force, but he was the first to work out the details scientifically.
108
and to prove the feasibility of a cylindrical space colony.
109
He was as interested in imagining the possibilities as he was in actually building it.
110
Actually building it, that's always the problem, isn't it?
111
You see, we can dream up these plans and even start them here on Earth, but to actually start them up there,
112
where structures really go mega?
113
we're going to need efficient, constant access to space from Earth.
114
A permanent structure, like a tethered space elevator, is a must -have for humanity to take the next steps.
115
And like the O 'Neill Cylinder, the theoretical engineering of the space elevator has already been worked out.
116
It's an unimaginably strong cable made of a carbon nanotube composite,
117
and it's anchored to a floating platform in the Pacific Ocean.
118
From there, it stretches skyward 100 ,000 kilometers to its endpoint.
119
It can lift payloads of 18 tons at speeds of up to 320 kilometers an hour.
120
A trip to low
121
Earth orbit, first floor, would take an hour.
122
This could happen.
123
It's just around the corner, cosmically speaking.
124
Now, the materials needed to build a space elevator will have to be two or three times stronger than anything we currently have,
125
but we're quickly closing the technological gap.
126
Now, what if there was a faster way?
127
In 1980, British scientist Paul Birch proposed an orbital ring system for access to space from Earth.
128
It's a thin ring surrounding the planet in low Earth orbit.
129
The cables would be tethered to it and hang down to Earth.
130
How is this better than a space elevator?
131
A space elevator needs a geostationary anchor out in space to function.
132
An object connected to a cable 36 ,000 kilometers long.
133
No cable we can make is strong enough for a distance that long.
134
But Birch's orbital ring gets around this by building a ring in low
135
Earth orbit about 500 km high.
136
It would move faster than orbital speed, which is what would hold it up.
137
The ring is the anchor, so the cable only has to reach about 500 km down to the ground,
138
and a shorter cable needs far less strength.
139
The orbital ring around
140
Earth could be a great ladder to get our civilization up into space.
141
Birch's orbital ring, like O 'Neill's cylinder though, is limited by its creator's restrictions to only use real materials of the age.
142
But nanotechnologist Tom McKendry worked out what a space cylinder could be
143
if built from materials that don't exist yet diamond -like structures made with molecular nanotechnology.
144
His version of a space habitat has a radius of 460 kilometers.
145
It's more than 100 times O 'Neill's.
146
Now, at some point, the limitations of strength and resources become secondary,
147
and the factor holding us back from building more sophisticated and wilder megastructures is energy.
148
Today, Earth only intercepts a billionth of the Sun's total energy output.
149
But what if we could capture nearly all of it?
150
In 1960, a scientist named Freeman Dyson came up with a concept for a sphere the size of Earth's orbit.
151
It would be a shell that encompassed the Sun
152
and captured all of its energy output it it's a mind -blowing megastructure in concept size
153
and ambition it's the kind of technological device
154
that would give the human species access to an almost infinite energy source
155
and power a quantum leap in our civilization's development it would be a necessary energy upgrade
156
and star powered springboard to explore our galaxy.
157
Now, unfortunately, the sphere is mechanically impossible to maintain, and Dyson knew it.
158
It was theoretically sunk by Sir Isaac Newton in 1687, 273 years before Dyson even thought of it.
159
Newton's Shell Theorem states that a rigid shell around a gravitational object would feel the pull of gravity evenly everywhere,
160
until a tiny external force hits it, and then the whole thing would immediately begin to drift,
161
eventually crashing catastrophically into the star itself.
162
Dyson's beautiful sphere gets destroyed by physics.
163
In Dyson's 1960 paper, he used the word shell to describe his idea.
164
Science fiction writers ran with the idea of the solid continuous sphere, but Dyson knew better.
165
In follow -up letters, he described a swarm of independent objects, each with its own orbit around the sun.
166
Each object is a relatively simple piece of technology that we could manufacture today.
167
Really, what keeps us from doing this is the quantity of objects needed to orbit around the Sun.
168
And even if we could somehow build that many
169
Sun satellites, getting these objects to the right place, orbiting the Sun, would be a megaproject in itself.
170
It might sound like a question from a science fiction novel,
171
but have we ever seen any evidence that anyone else has built a Dyson Swarm?
172
Have we detected any alien civilizations in the universe that might have built one of these things?
173
Well, it's not so far out of a question because Dyson himself proposed it even as he was originally imagining his swarms.
174
He reasoned that if an extraterrestrial civilization were capturing or reprocessing the power of their sun with technology like a Dyson Swarm,
175
there would be a measurable shift in the infrared spectrum of light from that star.
176
It's something called a techno -signature.
177
In 2024, a group of researchers found seven potential candidates.
178
Patterns observed in their sun's brightness were consistent with those expected if an alien civilization had built a swarm around their sun.
179
But in 2026, in a follow -up,
180
all these examples were dismissed as naturally flaring stars rather than a sign of megastructures.
181
So we have no evidence of a Dyson swarm existing elsewhere in the universe.
182
Is it even possible to build one of these?
183
Where would we even get the enormous amounts of metal and materials needed for such a massive project?
184
And where would we even start?
185
Well, according to Oxford futurists Armstrong and Sandberg, the project would start on the surface of Mercury.
186
And it would begin with a simple one square kilometer area of solar panels.
187
And 90 % of the energy from these panels would be used to break down chemical bonds
188
and process raw materials from mercury.
189
And 10 % would be used to propel these materials into space.
190
The materials are used to build solar collectors, which are placed in orbit around mercury
191
and beam energy back to the surface for further processing and to launch more material into orbit.
192
The process expands exponentially.
193
Based on a series of five -year cycles of replicating, processing, and launching solar collectors,
194
the project takes 31 years.
195
In that time, more than half of mercury would be dismantled and processed into solar collectors that get distributed around the sun.
196
The result is a Dyson swarm, and humans capture the entire power of the sun.
197
And leveling up to highly speculative science fiction territory,
198
writer Larry Niven ran with Dyson's concepts and invented the wildly imaginative Ringworld.
199
It's a ring like a gigantic wedding band that circles the sun.
200
It might look like a fragile, narrow band from a distance, but Ringworld is a true megastructure.
201
It would be 1 .6 million kilometers wide from edge to edge and have 3 million times the surface of Earth.
202
Building this would take hundreds, if not thousands, of years.
203
We'd have to strip mine half the solar system to get resources to build this.
204
But now that we've conquered the output of the sun, what's left to build?
205
Well, there's more.
206
There's so much more.
207
So, you're a future super president of the solar system, and you decide we all need to go visit another galaxy.
208
So what do you do?
209
Build an Earth -sized spaceship to send us off to Andromeda?
210
Maybe the best way to travel between galaxies is to take the thing we can't live without along with us.
211
Thank you.
212
A shakadov thruster is a theoretical mirror big enough to push the sun
213
and all the planets gently across the galaxy on the pressure of radiation alone.
214
This is space travel in style.
215
A massive sun -sized engine pushing us through the galaxy
216
while a swarm of sun satellites captures all its available power feels pretty majestic.
217
You might stop to ask, have we reached peak megastructure here?
218
Well, what if I told you that a Dyson swarm is actually a rather primitive device?
219
Because Robert J.
220
Bradbury went a step further.
221
A Dyson swarm still has cracks that let some energy through, and its simple design emits waste heat.
222
So, what if the sun were surrounded by a series of nested concentric layers,
223
each layer capturing the waste heat of the layer inside it, approaching 100 % usage of our star's power?
224
This additional energy is what we would need to power a massive sun -sized supercomputer, known as a matryoshka brain.
225
It's called a matryoshka brain after the Russian matryoshka dolls that nest inside of one another.
226
And its purpose could be a digital utopia where all of humanity's consciousness is uploaded.
227
Each person surviving for eternity in paradise.
228
It's an insanely long way from being realistic.
229
It would need a structure like a space elevator
230
or an orbital ring to lift material into space at rates we've never seen before.
231
And landings on extraterrestrial soil with the intention to reduce the planet to dust
232
and convert all that material into an orbiting mega -computer planet.
233
It's nesting interconnected layers, powering civilization into the next level.
234
What level is that?
235
Well, in 1964, four years after Dyson launched his sphere into the collective imagination,
236
Soviet astrophysicist Nikolai Kardashev introduced the idea that extraterrestrial civilizations could be ranked by their energy consumption.
237
Known as the Kardashev Scale, he initially proposed three types.
238
A Type 1 civilization has achieved the technological means to harness all the available energy from its home planet.
239
We humans are on our way to a Type 1 status, but we've got a few steps to go.
240
Well, a lot of steps to go.
241
A Type 2 civilization would be a massive step up from
242
where we are now it would be a civilization capable of capturing and utilizing the total energy output of its host star.
243
Imagine capturing all the Sun's power and being able to use it all.
244
These civilizations would have built some variation of a Dyson Swarm or a Matryoshka brain and harnessed the power of their star.
245
A Type III civilization would have leveled up way beyond its
246
own solar system to tap into the energy at the scale of its entire galaxy.
247
And following in the theoretical footsteps of Kardashev, others have added on to his scale.
248
So a Type 4 civilization would be a civilization harnessing the energy of the entire observable universe.
249
A Type 5 conquering the multiverse.
250
Even Omega civilizations that exist in a quantum state, rewriting space, time, and reality itself.
251
As a barely type one, we've got our work cut out for us.
252
Okay, we've seen that physics can be harnessed, technology can be developed, and energy can be captured in almost infinite quantities,
253
but the question that really matters is,
254
are we going to be the generation that drops the thread and abandons the line to the Arabian sands?
255
Or are we going to be like the generation that picked up the thread and finished building the Cathedral of Cologne?
256
Or the generation that came together to build the International Space Station?
257
Can we see past our immediate future and launch a vision that lasts millennia?
258
Do we have the right stuff to become a Type 3 civilization?
259
Click on the video on screen now to find out.
260
Because that's a story.
261
for another What If.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
