We are in a multidimensional world, and our world is in a multidimensional space?

Multidimensional world. Human understanding is limited, but we already know the three-dimensional, four-dimensional, five-dimensional, twelve-dimensional and other dimensions.

The world we can perceive is a three-dimensional world, and what about the world that we can't easily perceive?

Just because we don't know doesn't mean we don't.

The space we live in is a three-dimensional space, but we are also controlled by time, which can also be called a four-dimensional space.

This is actually just a concept, and different concepts have different understandings. Although we live in a three-dimensional space, all we can see is a two-dimensional plane, two eyes cross from different directions, and two planes observed at different distances overlap to produce three-dimensional vision that can judge the distance, because the human eye can only see three-dimensional, so it is difficult to explain more than three-dimensional.

Just as a person with normal intelligence who is born without one eye and one ear (so that there is no binocular effect and binaural effect), it is difficult for him to understand distance and direction, and he is likely to think that the world is two-dimensional. To put it simply: 0 dimensions are points, without length, width, or height.

One dimension is a line made up of countless points, only length, no width or height.

A two-dimensional is a surface made up of countless lines, with length, width, and height. A three-dimensional body is a body composed of countless faces, with length, width and height. Dimension can be understood as direction. To put it simply: n-dimension is the space formed by two perpendicular pairs of n straight lines.

Humans can only understand 3 dimensions, so the later dimensions can be constructed by mathematical theories, but it is difficult to understand them carefully. In quantum mechanics, we first assume that there are beings who live in two-dimensional planes, whose worlds are only long and wide, and who cannot understand the third dimension, the "high" dimension.

The living space is three-dimensional. Some people also call the living space four-dimensional, that is, the length, width and height of the three-dimensional space plus the timeline that runs through it, should be called four-dimensional space-time, not four-dimensional space.

There are theories that there is a 0-dimensional to n-dimensional space in the universe, but these are still conjectures and have no actual basis. Generally speaking, dimension 0 is a point, and this point has no length and width, let alone height, and it looks like it is nothing, so this dimension is difficult to understand and cannot be explained by the theory of the world. Just like the singularity before the universe is big, it is an infinitely small point, how small it is indescribable.

People depict more four-dimensional space, and if you add time, it is five-dimensional space-time. The general theory is that three-dimensional space is a node in four-dimensional space, and four-dimensional space is composed of countless three-dimensional space superimposed, so in four-dimensional space, you can see things in different stages at the same time.

We live in three-dimensional space, confined to the fourth dimension of space-time, for example, if you live in a plane, what limits you at this time is height, if you can break through the height, then congratulations on entering three-dimensional space, and the same thing that limits us to the past or back is undoubtedly the dimension of time. Whether there are creatures in the high-dimensional space needs to be verified, and it is recommended that you look at the super-metaphysical theory to study the high-dimensional space, if there are creatures in the high-dimensional space, then this kind of creature is quite terrifying The above is completely my hand-to-hand hit the most despised those pasting parties, I hope it will be useful to you Say more High-dimensional space is the first to have a result and then there is a reason, perhaps beyond the understanding of human beings, to say that the minimum speed of some ultra-high-dimensional spaces is faster than the speed of light, what does it mean to exceed the speed of light?We humans are just wretched creatures imprisoned in a three-dimensional space-time space-time.

I'm from the future).

We live in a three-dimensional world, but why is our shadow two-dimensional?

We think of ourselves as three-dimensional, and the universe as individuals thinks of it as one-dimensional, because there is nothing but time.

Our teacher said it was 4 dimensions, and I don't know about the rest...

Dimension is a way of thinking.

Our world is a visual experience projected into our brains. Because our vision is all 2-dimensional, the world is 2-dimensional for most people.

But you can say that our world is determined by three parameters: length, width and height, so the world is three-dimensional.

In the Buddhist scriptures, it is said that I am the world, and the world is me, which shows that in the concept of the Buddha, the world is zero-dimensional.

Albert Einstein connected time and space into a single point, the world is made up of 4 parameters, and the world is 4 dimensions.

The superfilm theory wants to unify quantum mechanics and relativity, so it creates an 11-dimensional world.

First of all, there is no need to talk about it, we normal people know it. Then there is the 4 dimension, we explain it through a coordinate axis, the so-called dimension, that is, there are different corresponding values on the corresponding axis or direction of the dimension. For example, length, width and height, you can reach any point at will, any three-dimensional coordinate.

In a word, change creates new dimensions.

Time can be a direction in the fourth dimension. However, time is just an understanding of human beings, a way of saying that, in fact, the time we humans define may be nothing more than the "length, width and height" in the "eye" of higher-dimensional organisms, which can be measured by units of length, and can be deduced from modern scientific research theories, 1 second is equivalent to the length of a light-second measured by higher-dimensional organisms, which is the famous time distance conversion formula. The so-called 4 dimensions are the superposition of infinite three-dimensional spaces, like countless pieces of paper piled up into a book.

Like the working principle of cinema, human consciousness travels at the speed of light in this "paper", resulting in the illusion of time. These four dimensions, in our human definition, are space-time bodies.

Then 5 dimensions, it's easy to say. With time and space, there is a timeline, a world line, like a movie line. Is it too monotonous, the beginning, process, and ending have all been decided.

Thus the 5th dimension was born, and again, the metamorphosis dimension. Draw a straight line on a piece of paper and set a line between two points, that is, you can determine a timeline if you determine the state and position of objects in all three-dimensional spaces at two points in time. What about that many timelines?

You can think of the multiverse, the parallel universe, this whole paper, you can draw countless lines. Each point corresponds to a point in time, a kind of descriptive coordinate of the position and state of all objects in three-dimensional space. Lines move into planes, just like 1D becomes 2D.

6 Dw? It's easy to say, it's easy to say.

In the above five dimensions, it is still the same situation, a past corresponds only to a future, a fixed destiny, and only a speculative world line. However, will there be such a structure, many-to-one? There is no necessary cause and effect?

Yes, that's 6 dimensions, multiple cause and effect, no process necessarily leads to the same result, and all cause and effect are scattered and ordered. Is it that at this point, the world is huge? That's not enough.

The higher dimensions are difficult for humans to understand, so I won't go into them one by one. In short, there is also the idea of infinite dimensionality, which can also be understood as relative dimensionality. For example, if you look at an object with a velocity of 1m s, others may see it at 2m s, or more precisely, it may be a variety of outcomes.

So what about the three-dimensional in our eyes, perhaps a point in other dimensions (zero-dimensional). As I said, time is a human illusion, and higher-dimensional beings may see it as a component of space. Then the higher-dimensional beings also have the illusion of time, and the higher-dimensional ones are regarded as space.

The cycle goes on and on, stretching to infinity. Such a world can already be said to be infinitely infinite to the infinite power.

That's it, there are many such literatures, and those who have doubts will learn more, and eventually they will have their own system.

Regarding the problem of dimensions, please refer to the string theory, the string theory under the 11th dimension and the 26th dimension are both valid, but it is generally believed that space has 11 dimensions, according to the membrane theory, the universe is the same as the earth, in the three-dimensional space on the five-dimensional membrane (saying that the 4th dimension is added to the time), from the current level of scientific development, this is a relatively correct answer, about the dimension, the absolutely correct answer is not yet available.

Human beings can perceive the four dimensions, and the fifth dimension refers to the boundless energy.

Theory M holds that the universe has 11 dimensions, 10 spatial dimensions plus one time dimension, and it is argued that if it is higher than this number, it will be unstable.

The following copy and paste: the first dimension is the position, which exists in space;

The second dimension is velocity, which exists in time;

The third dimension is velocity pointing, which exists in the (velocity) time direction;

The fourth dimension is state orientation, which exists in the spatial direction corresponding to its own shape;

The fifth dimension is the state corner, which exists in the roll corresponding to its shape;

The sixth dimension is the spin rate, which exists in the rolling time;

The seventh dimension is the spin equatorial axis direction, which exists in the rolling (velocity) time direction;

The eighth dimension is the spin equatorial axis directional drift rate, which exists in the temporal direction of rolling change (acceleration rate);

The ninth dimension is the direction of the spin equatorial axis pointing to the equatorial plane of the drift velocity, which exists in the rolling change (acceleration.

in the direction of time;

The tenth dimension is the acceleration rate (or force intensity), and the eleventh dimension is the acceleration (or force) direction.

Four, commonly referred to as three-dimensionality plus the dimension of time.

"Three-dimensional! ”

Can you imagine a four-dimensional world? ”

The child scratched his head and couldn't answer.

Yes, for humans living in three-dimensional space, the four-dimensional world is a very mysterious concept. Just as it is difficult for a small person living in a two-dimensional world (if one exists) to imagine a three-dimensional world, it is equally difficult for us to imagine a four-dimensional world. But just as we can study imagining three-dimensional objects by studying the projection of three-dimensional objects on two-dimensional objects, we can also study four-dimensional worlds by projecting three-dimensional objects in three-dimensional worlds.

We live in a three-dimensional world, but why is our shadow two-dimensional?

What is currently recognized is the mind, the three dimensions of space, and the fourth dimension of time.

There are four fundamental forces in nature: gravitational, electromagnetic, strong interaction, and weak interaction. What can unify the four roles of gravity, electromagnetic force, weak action, and strong action is superstring theory.

Feynman was opposed to superstring theory, and Yang Zhenning was not optimistic about it before. But the direction of superstring theory is undoubtedly correct.

Superstring theory is based on the principle of conservation of multidimensional space-time and symmetry. The multidimensional space-time of superstring theory is actually an infinite-dimensional space-time. The early superstring theory was a 26-dimensional space-time, which only allowed the existence of bosons, and later it was reduced to a 10-dimensional space-time, allowing bosons and fermions to coexist.

Bosons transmit force, fermions form matter, that is, 11 dimensions to 26 dimensions of space-time, only force exists, and below 10 dimensions can force and matter coexist. The reason why there are 26 dimensions, and no more, is because 26 dimensions are accurate enough to describe power. The 10-dimensional superstring theory solves the problem of the symmetry of bosons and fermions, the so-called supersymmetry.
