Why does the human brain only understand 3 dimensional space and not 4 dimensional space?

<> is just like the human eye can only see visible light, but not infrared and ultraviolet rays. On the contrary, many animals can see infrared, so humans can never understand what the world looks like through the eyes of animals.

The ant only crawls on the surface, which is equivalent to a two-dimensional world, and it can never see the eagle in the sky, how do you say it will understand that there are eagles in the world?

When the brain has the concept of time, it can also understand the process of the geometry of the object changing with time (for example, when the rectangular ice cube melts, its shape changes with time), so the human brain can understand the 4-dimensional space.

Because there is no such thing as a four-dimensional space. Three-dimensional space is real, and there are three dimensions of length, width and height to form three-dimensional things, which is easy to imagine. So-called"Four-dimensional space"Strictly speaking, it is three-dimensional space plus the change of time, not that space has four dimensions.

We live in three-dimensional space, we have only seen three-dimensional space, four-dimensional space is just a conjecture that we have expanded through mathematical and physical knowledge, there is no physical object for comparison or reference, so it is difficult for us to understand what kind of existence four-dimensional space is.

The so-called "summer insects can't speak ice" and the so-called "frogs at the bottom of the well" actually mean this.

Think about evolution, everything you have is evolved to adapt to your environment, and what do you do with the evolution of an environment that you don't have?

Space is big, and what supports this big is the co-creation of atomic space. The absolute big comes from the smallest micro, which is the truth of spatial transformation, the invisible elephant, and the big sound. This space is not called dimensional, it is the space of the avenue.

Speaking of several dimensions, they are all within the avenue space. The supreme dimension collapses to form one dimension, which is energy, potential, and possibly yin and yang. The second dimension is the concreteness of energy and potential, the object and the matter.

Stones, clothes, machines. The three-dimensional is the living matter, bacteria, ants, cattle and sheep, and people. The four dimensions are not supported by the material body, but should be supported by the energy body, the soul, the celestial beings, the ghosts and the gods.

The five dimensions, the life above the god level, the Tao level, the omnipresent level, this dimension should be within the atom, the highest god is three, and all things are born is three, which is the composition of the atom, yin and yang, order, and change. The space within the atom changes or collapses, releasing the energy that maintains order, or the energy that yin and yang drown each other, and the energy is one-dimensional. ......All things have spirits, energy is spirit, wind is spirit, stone is spirit, man and god are also.

Space is multi-dimensional, depending on the presence of the spirit or the observer.

One dimension has only a length, and the visual representation is a line.

Two-dimensional is a plane, with length and width, which is represented as the x-axis and y-axis in mathematics. For example, if you look at a ball, you can only see a cross-sectional circle.

Three-dimensional has length, width and height, x-axis, y-axis and z-axis, which is a three-dimensional world. The world we see with our naked eyes is a three-dimensional world. In the three-dimensional world, if you look at a single ball, you can see the whole sphere.

Four-dimensional is to add a timeline on the basis of three dimensions, just like a person has past, present and future time periods. In the state, a person cannot see the past and the future, but can see through time, and this process is the four dimensions. Living in a four-dimensional space, everyone can see their own self at various times.

Five-dimensional is to add space on the basis of four-dimensional, for example: a person enters a company as a white-collar worker after graduating from college, this is a lifeline, if the same person chooses to go abroad after graduating from college to become a scientist, this is another lifeline. The fourth dimension can only see the lifeline of becoming a white-collar worker, while the fifth dimension can see the lifeline of becoming a scientist.

Hope it helps!

It is the scope of the existence of matter.

This dimension is independent lines, and these lines are perpendicular to each other, and we are three dimensions perpendicular to each other.

You can simply think of it as a projection relationship. One dimension is a projection of two dimensions, two dimensions is a projection of three dimensions, and three dimensions is a projection of four dimensions. And so on.

In the three-dimensional space of our existence, the past is the past, and we cannot find yesterday or tomorrow. But in the four-dimensional space, time is a variable, and everything in the past, present, and future exists there. Therefore, when we went to see the interview between Professor Liu Feng and Liang Dong, we mentioned the problem of dimension, and also put forward a scientific concept, that is, the disease that cannot be seen in the three-dimensional world can be improved by adding a dimension.

This has actually been proven in the traditional culture of the East and the West.

But no one knows what the four-dimensional space is like, and all the conjectures we make now are just conjectures, and no one can give a definite conclusion about these things about space and dimensions. Because we have no way to verify it now, if people can break the dimension of space and enter a higher level of space, then there will inevitably be a big change in the way human beings interactThat is, we have to find a quantity in a direction other than length, width and height, and it is the path that we can take.

It is impossible to determine the form of existence, so it cannot be imagined, let alone speculated, and can only imagine the form of his existence, which scientists are currently studying.

Because human beings have no concept of the mental space at all, they have no cognition, and people's eyes cannot see, so they are limited by what they see.

The reason why we can't imagine the four-dimensional space is that the space we can perceive is only three-dimensional, and our imagination is only based on our usual perception of the reality of the world. For example, let's imagine a red swan. Although there are no red swans in reality, we can combine the common red and swans in real life to form an image of a red swan in the brain.

Because with the wisdom and technology of human beings now, they can only discover or put forward a three-dimensional or four-dimensional view, just like you said, ants only recognize that the space where it is located is 2 dimensions, and we human beings realize that the space where it is located is 3 dimensions.

If we simplify the space we intuitively know to a flat Euclidean space, then we can know that the so-called three-dimensional description method actually comes from the coordinate system of analytic geometry (such as the Cartesian Cartesian coordinate system, of course, the polar coordinates are the same), we need three independent parameters to locate a point, one less is not enough, and one more is redundant.

In order to understand and express the space we perceive, we invented geometry to express it in a three-dimensional coordinate system.

Because to determine a point, only three independent parameters are needed. Whereas a point is the smallest, most basic geometric element.

In the beginning, when there was no concept of coordinate system and dimension, we were faced with a huge natural space and could only measure length.

At this time, we will find that when we have an origin, we need a length, an angle, and a height, or a length, two angles, in short, three numbers to determine a point.

There is no why, practice always proves that no more, no less, is three, based on the premise of real numbers and Euclidean geometry.

Three-dimensional space, in daily life, can refer to the space composed of three dimensions: length, width and height. Moreover, the term "three-dimensional space" used in daily life often refers to three-dimensional Euclidean space.

A space where the location of a point is determined by three coordinates.

The objectively existing real space is three-dimensional space, with three measures: length, width, and height. The concept of multi-dimensional space introduced in mathematics, physics and other disciplines is a scientific abstraction made on the basis of three-dimensional space. It is also called three-dimensional space.

The end of the world in 2012 is a complete joke.

Ants are low-dimensional animals, but they live in high-latitude space, so it is basically difficult for humans to break through in the four-dimensional space. The fourth dimension is time, and if you want to go beyond time you can only go beyond the speed of light, but nothing will exceed the speed of light, because it violates the laws of physics. Under the laws of physics, the maximum speed of any object with mass is the speed of light and can never exceed light, but it does not mean that it cannot participate in time travel beyond the speed of light.

Once you reach a certain speed of light, your time passes very slowly, i.e. you participate in time travel. I know it's hard to understand this theory, for example, if you're sitting on a very fast train, your train is at the speed of light, and you're on the train for a week, and you've been out there for 100 years.

The speed of the train will make all the objects pass quite slowly, your watch, etc.

If 2012 is the end of the world, don't you think it's ridiculous?

We're going to be incredibly intelligent, but a lot of vision just might spoil our brains, and we're going to have an unprecedented amount of knowledge because we can see all the three-dimensional worlds that the human brain can't.

There will be no "end of the world" in 1012, that's for sure, but they won't enter the four-dimensional space, their thoughts are similar to Taoism, they are all cycles, but Taoism is 60 years, they have a little more.

Four-dimensional space refers to the space composed of four dimensions: length, width, height, and time.

Three-dimensional space refers to the space composed of three dimensions: length, width, and height.

Four-dimensional space has more dimension than three-dimensional space, and for human beings, three-dimensional space is equivalent to a space composed of only the length, width and height of a certain point in time, while four-dimensional space is a series of spaces composed of length, width and height.
