Pratique du Shadowing: All 7 Dimensions Explained in Detail (From 0D to Infinity) - Apprendre l'anglais à l'oral avec la vidéo

Only one dimension has vanished from reality.

Depth your body has become absolutely flat.

You can't turn around and your blood has stopped flowing because your veins no longer have volume.

But these are minor details compared to what awaits you in the fourth, fifth and seventh dimensions.

Today we'll drag your body from the zeroth dimension to the seventh where the human brain simply shuts down.

One important note before we go further: the higher we climb,

the more we use dimensions as a metaphor to visualize levels of reality that we cannot see directly.

But first, the basics.

What exactly is a dimension?

Forget about portals and magical realms.

In the simplest sense, a dimension is an independent direction, or a degree of freedom, used to define an object's position.

zero directions to move.

If we forcefully squeeze a body into the zeroth dimension, no shape remains, only a coordinate,

a mathematical point with no size.

In such a world, there's no space to move, and the very idea of moving loses its meaning.

Absolute claustrophobia.

You seemingly exist, but to the rest of the universe, you simply don't exist.

Let's take a step up to the first dimension.

We are granted exactly one degree of freedom.

You become an infinitely thin line.

Now you have length, and you can only move forward or backward, and that's it.

You can't turn around or bypass an obstacle.

If someone else appears on this axis in front of you, you are simply stuck forever.

The concepts of "up" or "sideways" simply don't exist here.

You aren't just stuck on a line, you have become a creature for whom any obstacle is the end of the universe.

We take this line and stretch it at a 90 degree angle.

Welcome to the second dimension, the plane.

You now have length and width.

Your entire world looks like a drawing on a piece of paper.

But the most interesting part here is how you perceive this world.

In 1984, mathematician Edwin A.

Abbott gave us a useful way to picture this.

For simplicity's sake, remember this main rule: a creature usually perceives the world through projections

and cross -sections one dimension lower than itself.

If a 2D character on paper looks at a drawn circle, they won't see a circle.

Imagine putting your right eye at the level of a table surface and looking at a coin lying flat from the side.

You won't see a round shape, you will see merely a flat horizontal line.

In a flat world, absolutely everything looks like line segments of varying lengths.

indeed a circle and not a square.

A flat creature would have to physically walk around its perimeter.

Only then could it understand the object's true shape.

If this 2D character draws a square house around itself, it will be absolutely safe from other flat beings.

To them, it has disappeared behind a wall.

But we, beings from a 3D world, look at this piece of paper from above.

We see everything simultaneously: the walls of the flat house and the character inside it.

We can simply lower a finger from our third dimension,

neighbors, but it's an open box to a being from above.

Keep this paradox in mind, we'll need it shortly.

Let's pull this plane upward at a 90 degree angle.

Enter our cozy three dimensional world.

Physicist Paul Ehrenfest demonstrated that if there were more than three spatial dimensions,

the familiar laws of gravity would change so drastically that stable planetary orbits and atoms would become impossible.

depth appears, but due to that very rule of vision, we live in a total illusion.

Strictly speaking, our eyes do not receive a ready made 3D picture.

A flat 2D image falls onto the retina, and the brain reconstructs the sensation of depth using cues.

The disparity between our eyes, perspective, and shadows.

You see a closed safe, but you don't see what's inside.

Look at your monitor.

You can't see what's behind it until you walk around it.

In a 3D world, we only see the outer shells of things.

To see the inside, we must break the shape.

And now, let's step into the fourth dimension.

We add another coordinate, independent of the three spatial ones.

We can't display it on a screen as a normal direction, but in physics, time often plays the role of this coordinate.

In 1908, Herman Minkowski proposed viewing space and time as a single, unified structure.

In 4D, time ceases to be an abstract flow.

The easiest way to grasp this is through the timeline in video editing software.

The viewer watches the video frame by frame, while the creator sees the whole strip of the video laid out on the screen at once.

A 4D being looks at our three -dimensional universe exactly the same way we looked at that flat piece of paper.

It sees everything all at once.

4D being can interact with different segments of time, it doesn't need to break open the safe today.

It simply reaches back to the moment yesterday when the door was open.

To you trapped in the now, the object will simply vanish from the locked safe.

So what happens to your body?

You're no longer a human living life second by second.

Since time is now a physical direction, your body is permanently stretched along it.

Imagine a giant, continuous space -time worm, made up of millions of your copies.

At one end of this structure is a baby being born.

Further along, this long body rise through space, here it is walking to school, here it is sitting on a chair right now,

and finally it ends as an old person taking their last breath.

In 4D, there's no past or future.

There is no movement.

There's only this giant, frozen monolith of your life from beginning to end.

To a four -dimensional being, your life is not a story, it is an object.

But the 4D monolith is just one rigidly fixed line.

Let's take a step into the fifth dimension, and here we transition from strict geometry into a convenient PopSci metaphor.

What could the next direction be after time?

Possibility.

The axis of alternative outcomes.

In quantum mechanics, this is Hugh Everett's many worlds interpretation.

In 4D, you had only one destiny.

But if we imagine every event and every choice as a crossroads, then in the fifth dimension,

your temporal worm splits in two at the moment of every outcome. and again.

Your body in 5D turns into a colossal, infinitely branching fractal.

A massive tree, as it were.

A perfect example of how this feels is the video game The Altars, where every new clone at the base is you, having taken an alternate branch.

What were the massive narrative flowcharts in games like Detroit Become Human?

Here, the branch where you become all, in the branch where you're watching this video right now, all exist simultaneously.

For a five dimensional being, there's no concept of fate or inevitability.

100

It sees this entire fractal of your lives as a single whole.

101

You're no longer one person.

102

You're an entire forest of all the people you could have become.

103

Moreover, to it, these alternate realities are not separate worlds.

104

They are simply different directions in space.

105

of lives is constrained by the laws of our physics.

106

So we collapse your entire giant tree of probabilities back into a single point and pull another perpendicular axis out of it.

107

Welcome to the sixth dimension.

108

In some versions of string theory, entire landscapes of possible universes emerge.

109

For this video, we can picture it as the next level.

110

No longer different destinies within the same physics, but entirely different physics altogether.

111

Here lie universes with completely different fundamental constants.

112

Worlds where gravity is a thousand times stronger, worlds where the speed of light is different,

113

worlds where atoms fundamentally cannot bond together.

114

And at this stage, the concept of anatomy simply loses its meaning.

115

A body is only possible where the right laws exist, such as the right chemistry, stable bonds and enough time for processes to unfold.

116

In the sixth dimension, Nothing is left of your body.

117

You're no longer human.

118

You're no longer a branching worm.

119

You become pure information, an abstract mathematical structure that links the concept of your existence across all possible variants of physical laws.

120

To reach the seventh dimension, we take this entire infinite network of 60 universes with different laws of physics,

121

collapse it into a single point, And we stop.

122

The seventh dimension in this scenario is no longer a specific physical axis, but a final metaphor.

123

The space of all logically possible realities.

124

Let me say that again.

125

The space of all logical possible realities.

126

In the seventh dimension, the very concept of existence, or an event, loses its meaning.

127

Thank you simultaneously.

128

All possible variants of universes, all conceivable and inconceivable laws of physics,

129

all timelines from the beginning to the end of time.

130

There is no action here.

131

Action requires change, and change requires familiar time.

132

But in 7D, nothing is created...

133

How you doing?

134

You know what?

135

I'm in the middle of recording.

136

Can I call you back in a few minutes?

137

Okay, bye.

138

But in 7D, nothing is created and nothing disappears because everything that could logically exist is already permanently locked into this structure.

139

It's not a process.

140

It's an absolute, infinite, frozen map of everything.

141

It's not just a library of books.

142

It is a library of all possible alphabets, all languages, all stories, and all laws by which those stories are created could be written.

143

So why don't we go further?

144

Because at this stage, human logic reaches its limit.

145

The mathematics of string theory allow us to calculate the 8th, 10th and 11th dimensions, but there,

146

these axes represent microscopic, curled up spaces.

147

Describing them in macroscopic terms is physically impossible.

148

Our brains evolved to hide from predators in a three dimensional world, not to comprehend absolute infinity.

149

So, Let's come back.

150

Exhale.

151

And look around.

152

The walls of your room are solid again.

153

Your time moves only forward.

154

And everything inside the closed safe or behind your back remains a mystery to you.

155

Because you only see the flat 2D shell of things.

156

We live in a very narrow, limited, but perfectly balanced geometric incubator.

157

Enjoy this 3D illusion.

158

is its end, subscribe to the channel.

159

See you next time.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
