Shadowing Practice: What If you Could See the 4th Dimension? - Learn English Speaking with Video
Creando lección...
1
Today, we're turning you into a multi -dimensional super being.
2
You'll be able to be anywhere and any place at any time you want.
3
Walk through walls on a whim, melt through the steel doors of a bank vault, and just take what you want.
4
That doesn't sound legal.
5
But that stuff is just child's play compared to what you can really do.
6
You can see through anything.
7
As you walk past a stranger in the street, you notice something.
8
Turn back, reach into their body, and remove a cancerous tumor, saving their life.
9
For a little R &R, you sip margaritas and watch the ancient Egyptians build their pyramids in a time lapse.
10
Their secrets are interesting, but you're already on to bigger adventures.
11
You stand at the center of the Sun just to see what it looks like in there
12
and to work on your tan.
13
You surf the rings of Saturn.
14
You defy physics as we know it and travel throughout the universe, instantly appearing on planets millions of light years away.
15
In terms of capabilities, you are so far above the old mythical gods and their cheap tricks.
16
Compared to gods like Zeus, who only controlled thunder and lightning, you make them look like ants.
17
You see through time.
18
You understand and control everything in our three -dimensional world.
19
Okay, enough, enough.
20
At this point, you're probably wondering, how did I get these powers?
21
Why is this so awesome?
22
Well, to understand your new life as a four -dimensional super being, I'm going to have you relive every single dimension you came up through.
23
But don't let this 4D business go to your head.
24
Four dimensions are only the start.
25
Compared to being in the fifth, sixth, or even twelfth dimension, you're an inchworm trapped on a two -dimensional branch.
26
Okay, to understand dimensions, let's take you back to zero.
27
Yeah, you're now in a place where there are no dimensions at all.
28
A single dot that has no space, no size.
29
Even a pencil mark on a piece of paper has thickness and dimensions.
30
But where you are right now is just a theoretical point.
31
Now, from your position in a zero -dimensional space, you would see nothing and there would be no place to go.
32
So it's pretty boring as far as dimensions go.
33
But add one dimension, and we upgrade you to a one -dimensional space.
34
Now you live on a line.
35
In this line universe, you'd only be aware of the line ahead of you and the line behind you, nothing else.
36
In fact, you'd be looking at the line head -on, so it would just look like a dot ahead of you and a dot behind you.
37
In theory, you could go forward along the line forever, but that's it.
38
Let's call this length.
39
It's slightly more exciting than zero dimensions, but not by much.
40
Add yet another dimension and now you live in a world with another line at a right angle to the first one.
41
You exist on a surface now.
42
This is width, something I'm learning a lot more about as i get older now you can go forward backward
43
or in any combination of these two directions you can slide around on the surface as much as you like
44
but there's no thickness to this world it's perfectly flat as
45
you move around with your newfound freedom in this 2d world you would see everything edge -on.
46
Everything would look like a line.
47
In two dimensions, a circle would appear just as a line, the length of its diameter.
48
The only reason a representation of a two -dimensional circle appears to look like a circle is because, as three -dimensional beings, we look at it from above.
49
Yeah, being one dimension up from any other dimension automatically gives any being god -like powers over
50
that lesser dimension
51
if a three -dimensional being wanted to imprison you in your
52
two -dimensional world all they have to do is draw a
53
line around you no matter what you did you couldn't escape you couldn't step over
54
that line there's no up no down no over
55
or under for you
56
and unfortunately for you you've come down with a life -threatening case of appendicitis while visiting the 2d world But even worse,
57
your 2D doctor has a hard time finding your appendix because they have to look through you edgewise to find it.
58
And if they do find it, well, they'll have to cut through you to get at it.
59
But you don't have to worry because a three -dimensional doctor comes to your rescue.
60
Because you're perfectly flat, you have no layers, so a three -dimensional doctor looking down on you can see everything that is you.
61
They can clearly see your appendix, and they don't even have to pierce any skin to remove it.
62
They just pluck it out.
63
And for you, it would just disappear.
64
But when a 3D doctor comes to visit you in your 2D world, that's when things get really weird.
65
Because a three -dimensional being visiting a two -dimensional world would appear as only a cross -sectional slice of them.
66
The 3D Doctor would appear out of nowhere to you, a line of varying width, and then disappear into thin air as they pass through.
67
It'd be like seeing magic or being haunted by a ghost.
68
But you don't have to think about it for very long, because you're getting another major upgrade.
69
Yeah, we're giving you the dimension that makes us who we are.
70
The third dimension, depth.
71
Suddenly, the world opens up to you.
72
You're back in familiar territory.
73
Objects have volume and mass.
74
And we can see this volume.
75
A circle can be a sphere, and you can see all around it, and hold it, and throw it, because it can also move in three directions.
76
Plus, it contains space, volume for stuff to be inside of it.
77
Now, if you had appendicitis here in three dimensions, well, that same doctor who saved you back in the two -dimensional
78
world would have to look through you using x -rays to examine your appendix.
79
And if they wanted to remove it, well, they'd have to cut through all your layers to get at it.
80
You should really boost your fiber intake.
81
You're getting appendicitis a lot.
82
Now, if we wanted to imprison you in a three -dimensional world, we'd need a cube.
83
Trapped inside, you can move up, down, right, left, any combination of those, but you're not getting out of this cube.
84
Part of why we love the three -dimensional world is because we're a product of it.
85
It's our home.
86
But without all three of our familiar dimensions,
87
it's arguable that literally nothing as we understand it or experience it would exist.
88
It's also why it's a big leap for us to step outside of it.
89
So take one last look at your comfortable three -dimensional world
90
because you're about to leave it for some very unfamiliar territory and godlike powers.
91
Okay, here we are at the edge of our perceptions, and you're about to take a jump into a dimension beyond anything you've ever known.
92
The fourth dimension.
93
But what does that mean?
94
Well, there are a few different ways to look at dimensions.
95
One way is through the lens of physics.
96
First, you might be surprised that as far as physics is concerned, you're already a fourth dimensional being and you don't even realize it.
97
Yeah, Einstein theorized that time is the fourth dimension.
98
And time is something we're all very familiar with.
99
If three dimensions give us volume, then time gives us events.
100
If time didn't exist, nothing would happen, or everything would happen, but all at the same moment.
101
We live in three dimensions, but we move in time.
102
Meet you at the gym?
103
Well, that's a location in space, but if I say meet you at the gym at noon, then that's a location in space and time.
104
Also, if I say meet you at the gym at noon, count how many appendages I have, because you're likely talking to an alien.
105
Now, we might be creatures of this fourth dimension, but we don't have access to time.
106
Except for Marty McFly and Doc Brown, we happen to be very terrible time travelers.
107
In fact, it seems like we are trapped by time, unable to change speed or direction.
108
We're stuck going in one direction and traveling at the, more or less, constant speed of one second per second.
109
That is, unless you're accelerating.
110
Einstein's theory of relativity opens up a whole host of interesting… time travel options
111
if you watched interstellar well you'd know that accelerating
112
and being in deep gravity affect the rate at which you experience time relative to an outside observer
113
as you sink deeper into gravity you slow down crawling through time like you're trapped in slow motion now
114
if you wanted to time travel you could hitch a ride
115
on an ever accelerating a rocket ship around a black hole and pop back to Earth.
116
The journey for you might only take an hour, but you could wind up thousands of years in the future.
117
Good luck getting close enough to a black hole, though.
118
Now, in our everyday lives, we experience time like a movie, exposed to slices or frames of time as we move forward,
119
never being able to see beyond the present, and only remembering the past by storing it in our memories.
120
So, let's give you access to the fourth dimension of time.
121
Now you can see everything that's happened before and everything that's going to happen in the future.
122
You can see the timeline.
123
You hold it in your hands like a strip of film.
124
You can scroll up and down through it.
125
You can go to any spot in the filmstrip at will.
126
Now, if we tried to trap you inside that cube from earlier,
127
well, you could simply just move to a time either before or after you were trapped in the cube, or before the cube even existed,
128
or long after it was destroyed.
129
Now you have access to a new dimensional direction.
130
You could appear and disappear anywhere.
131
And also, knowing what has happened before and what is about to happen would give you amazing powers.
132
Like, if you were in university, well, just go forward in time.
133
Check the answers to the test and write them down.
134
Boom, A -plus every time.
135
Yeah, well, that might sound awesome, but what's the value of a university education when just playing the lottery and getting mega -rich would be a no -brainer.
136
You'd just have to zip into the future, look up the winning numbers, and skip back in time to play them and collect your winnings.
137
No job or degree needed.
138
But really, what's the point of money
139
if you can just go back in time and alter the deed to any house or boat or anything, and just make it yours to begin with?
140
The world is your oyster.
141
Or is it?
142
You see, time travel might have some serious complications.
143
There are two main schools of thought about it.
144
In the first case, you see an accident happen, a car hits a pedestrian.
145
Of course, you step back in time and stop that person from stepping out into traffic, saving their life.
146
But now that person goes on to become a careless scientist and makes a virus that wipes out humanity.
147
Or on a whim, you travel to ancient Egypt to unlock the secrets of how the pyramids were built.
148
You're careful not to be noticed or to touch anything, but you accidentally kill a mosquito that lands on your arm.
149
Because of you, that poor mosquito never gets the chance to spread the malaria it carries, subtly altering the course of Egyptian civilization.
150
Then, 2 ,000 years later, the Egyptians defeat the Romans, instead of the other way around, and Rome collapses centuries earlier,
151
and history has changed forever.
152
Boom, you're speaking Danish.
153
Durvelkommen.
154
Every person you interact with, every lottery you win, every step you take, changes the timeline.
155
It's called the butterfly effect, and it makes time travel a messy proposition.
156
As a four -dimensional time -traveling being, you see these changes ripple out from you as you go across time.
157
But what if the timeline isn't changeable?
158
Determinism says that nothing can be truly changed because the outcome of everything is already set.
159
After all, if you can see the future, then it's already set.
160
In this case, you've always been the fourth -dimensional traveler that you've become, and everything you do has already been done.
161
Nothing's new.
162
You can travel up and down the timeline of human history,
163
geological history, cosmic history, and everything you do and see has already happened.
164
Controlling time could be the most amazing curse you've ever received, or it could just be a Disney Express pass to the best ride in the universe,
165
but one you only get to watch and not interact with.
166
But what if we look at the fourth dimension through the lens of geometry?
167
What about the physical fourth dimension?
168
Four -dimensional physical space is a mathematical description of space beyond three dimensions.
169
If length is perpendicular to width and depth is perpendicular to both length and width,
170
then this new direction is perpendicular to all three.
171
Think of a 3D cube.
172
No, I'm not trying to imprison you again.
173
If you take 4D geometric space and project it out from every corner of that three -dimensional cube,
174
well, that's a 4D hypercube called a tesseract, and it looks like a cube inside a cube.
175
But that's only a three -dimensional representation of four -dimensional space, a shadow of the reality.
176
It's actually impossible to accurately represent 4D physical space, unless we're already in the fourth dimension.
177
But you can see it, because we're upgrading you!
178
Say goodbye to the constraints of the physical world, and welcome to your new life as a four -dimensional super being.
179
By the standards of our three -dimensional space, you now have the powers of a god.
180
The first thing you'd notice as a four -dimensional being is
181
that you could look back on our three -dimensional world and see everything.
182
Nothing would be hidden from you. To you, our layers would be flattened out and easily accessible in the same way
183
that we would see all the layers of a 2D being.
184
You can walk into the most secure bank in the world and see right through the concrete and steel -encased vaults.
185
Your access to the fourth dimension would allow you to just slide through any wall.
186
You can just step in and help yourself.
187
Safety deposit boxes are now just open trays waiting for you.
188
Jewels, stacks of money, gold bars.
189
You take what you want.
190
But this is all just Dollar Tree stuff.
191
Inspired by your newfound powers, you zip over to the Smithsonian Museum of Natural History, walk through the door, melt through the security systems,
192
and grab the Hope Diamond.
193
It looks good on you.
194
Someone shouts at you to stop.
195
You've been spotted.
196
You might be a four -dimensional being, but you're not invisible.
197
Just as a 3D object passing through a 2D world would appear like a line
198
that varies in length depending on the width of the object at the point of intersection,
199
To us, if a 4D being or object intersected with our world, we'd only see a 3D slice of it.
200
We wouldn't be able to see or experience the whole object.
201
A part of it would be obscured because we only see in three dimensions.
202
So the museum guards aren't even sure what they're seeing.
203
They only see a ghostly slice of you moving through their reality, appearing instantly and disappearing just as fast they wouldn't know what was happening.
204
Regardless, they'd draw their guns.
205
Now, what would a three -dimensional bullet do to a four -dimensional being?
206
Even if it happened to hit the slice of you that the guards saw, the damage would be minor,
207
like a two -dimensional bullet with absolutely no thickness passing through your three -dimensional hand.
208
or you could just step aside and leave the bullet back in three -dimensional space.
209
But if for some reason you were caught and the police tried to trap four -dimensional you inside the same cube,
210
or in this case jail cell, you would just move in your new four -dimensional direction and slide right through those iron bars.
211
You'd be unstoppable.
212
Money, access, any restriction anywhere, gone.
213
Want to visit the King of England?
214
Well, walk right up to him.
215
Want to eat lunch in the Oval Office?
216
Grab a couple Big Macs and enjoy.
217
Another cool feature of your new powers?
218
When you look down, you can see everything underground.
219
At a glance, you'd be able to map oil deposits deep inside the earth, pick out seams of gold trapped in rock,
220
and find every buried treasure that's ever been lost to time and the tides.
221
Now, our human society is built upon privacy and access to information, but you could sit in on any conversation,
222
reach into any locked drawer, or slide into any high -security setting.
223
Corporate plans, state secrets, nothing would be beyond your reach.
224
You would instantly be the most powerful being on the planet.
225
Slipping in and out of the third dimension, you could change the course of world events any way you wanted.
226
But now you're so rich and powerful that material possessions quickly lose all their meaning.
227
So you turn your attention to other powerful things that you can achieve with your powers.
228
Just like the three -dimensional surgeon could see all of the two -dimensional you, well, you've now harnessed the power of the fourth dimension.
229
You could see right through any three -dimensional person.
230
Looking through a 3D person, you see every organ, every bone, and even deeper, every process and cell.
231
You're able to diagnose at a glance.
232
You spot a cancerous tumor, reach in and remove it.
233
And you're able to do it without even making an incision.
234
To us mere three -dimensional beings, you'd appear as a series of mysterious events.
235
Unexplainable phenomena to scientists, ghostly magic to others, and to some, miracles from above.
236
From the vantage of your fourth dimension, you spend your days appearing in our world as a friendly ghost,
237
leaving behind a trail of medical cures and world -changing interventions.
238
Now, despite your powers over our dimension, you'd have to live by the rules of the fourth dimension.
239
But there's another dimension.
240
Just as it's a mental stretch for us to imagine a fourth dimension,
241
it gets increasingly hard to imagine what a fifth dimension would look and feel like.
242
But we do know that with every additional dimension,
243
you would be entirely, completely changing your ability to see into the previous dimensions.
244
Just like a 3D being possesses god -like powers to a 2D being, and a 4D being appears like a god to us,
245
a 5th dimensional being would have unimaginable powers inside the 4D world.
246
So we can guess that as a 5th dimensional being, you'd be able to look back on the 4th dimension and see it completely.
247
Nothing from the 4th dimension would be hidden from you, and you'd be able to trap your four -dimensional self in a four -dimensional cage.
248
But going forward from here, we're going to need a bigger brain.
249
This is where the limits of our perceptual common understanding end.
250
Above the fourth dimension, things get really strange.
251
Space isn't necessarily expanding at this point, it's folding in on itself.
252
We're getting into the realm of subatomic geometries,
253
theoretical shapes and dimensions that some believe could underlie our reality and everything we perceive.
254
And some say the progression is this.
255
The fifth dimension represents a branching out point between parallel universes.
256
Every quantum decision that could go differently does go differently in an adjacent fifth dimensional slice.
257
The sixth dimension is the space of all possible histories of all possible universes with the same starting conditions as ours.
258
And in the seventh, universes with different starting conditions entirely, different laws of physics, different constants.
259
Dimensions 8, 9, and 10 are said to describe the full landscape of every possible universe that could mathematically exist.
260
And if you could travel freely through all of them, you'd be a multiverse -jumping super -being.
261
You'd travel to the core of the Sun just to see what it was like,
262
and then travel to every version of the Sun in every color at every point in time that it ever existed, and didn't exist.
263
You'd surf the rings of Saturn, then visit the rings of Earth, and then visit the Universe where every planet in our Solar System is Earth.
264
Jump to another galaxy millions of light years away in an instant.
265
Geometry and physics become the same thing.
266
You can exist anywhere, anytime, any reality.
267
It's a breathtaking idea.
268
But there's just one problem.
269
None of that is what the extra dimensions actually are.
270
The reality is far less cinematic, and in its own way, far more strange.
271
String theory is a mathematical framework that describes the fundamental fabric of the universe as vibrating one -dimensional strings.
272
And this theory requires extra dimensions to function.
273
Without additional geometric directions for those strings to vibrate into, the quantum calculations just break down.
274
But these dimensions aren't vast cosmic corridors leading to parallel universes.
275
They're almost incomprehensibly small, curled up around themselves at scales so tiny they may never be directly observed.
276
Not gateways to other realities, but seams in the fabric of space itself.
277
Now, if you decide to follow theoretical physics down the rabbit hole, there's even more.
278
Bosonic F theory proposes a 28 -dimensional theory.
279
And here's the fun part.
280
It's 26 directional dimensions and 2 time dimensions.
281
Imagine going along your timeline forward and backward and then taking a left.
282
These are just our theories today, but there's no telling what the reality actually is.
283
Though string theory has a lot of contemporary support, no theory has been completely proven.
284
So there could be 30, 5 ,000, or infinite dimensions.
285
What would you even be like after transiting through so many dimensions?
286
But what does it feel like to be a being with access to infinite dimensions?
287
Dimension after dimension, you'd shed the perceptions of the previous one, gaining new perspectives and powers over the previous dimensions every time.
288
Now, at the top of the dimensional ladder, you can access everything, every creation, every planet, every timeline, every multiverse,
289
and you see and understand everything at the same exact moment.
290
The further up the ladder you go, the less like a super being you actually become, and the more you mesh with our concept of reality.
291
All outcomes already exist for you.
292
There are no choices to be made because they've all already been made.
293
And there's no cause, no effect.
294
All meaning would cease to exist for you.
295
Even the concept of all -powerful, all -knowing doesn't make sense anymore.
296
You're more like a fundamental particle at this point, traveling through incredibly complex packets of foldable space.
297
Now, the completely multi -dimensional version of you and
298
that theoretical zero -dimensional point we talked about at the beginning are somehow the same.
299
Strange, isn't it, how everything and nothing meet in a single, unified point.
300
You've reached dimensional enlightenment and explored all of space and time.
301
Incredibly, though, there's something that exists outside of dimensions and physics,
302
and it might be found if we traveled to a time before time began, before the Big Bang.
303
But that's a story 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.
