How many dimensions does the real world exist?

"Dimension" is a measure in three-dimensional space.

In terms of coordinates, plus time, space-time is interconnected to form a four-dimensional space-time. Now the theory of scientists is that the entire universe is eleven dimensions.

It's just that human understanding can only understand dimensions, to use an analogy: an intelligent creature lives around us, but can only understand two dimensions, so is it in a two-dimensional world? But around them, we clearly think that they are three-dimensional, that both sides are intelligent beings, who is right and who is wrong??

V: There is no length, width or height, just a point, such as a singularity.

One-dimensional only in length.

The two-dimensional flat world is only long and wide.

Three-dimensional length, width and height Three-dimensional world The world we perceive and see with the naked eye Three-dimensional space is the space where the position 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 based on three-dimensional space.

Four-Dimensional A Concept of Space-Time Most of the references to "four-dimensional space" in everyday life refer to Albert Einstein.

In his book General Relativity.

and Special Relativity.

The concept of "four-dimensional space-time" mentioned in . Our universe is made up of time and space. The relationship between time and space is that a time axis is added to the structure of space compared with the three axes of length, width and height of ordinary three-dimensional space, and this time axis is an axis of imaginary values.

According to Albert Einstein's theory of relativity, the three-dimensional space we face in our lives plus time constitutes the so-called four-dimensional space.

One dimension is a line, two dimensions are a surface, three dimensions are static space, and four dimensions are dynamic space (because of time).

The parameters that we have to change in physics to describe a changing event. This parameter is called a dimension. A few parameters are just a few dimensions. For example, to describe the position of a "door", you only need angles, so it's one-dimensional, not 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.

Because the human eye can only see three dimensions, it is difficult to interpret more than three dimensions. Just as a person with normal intelligence is born without one eye and one ear (how sad. So that there is no binocular effect, binaural effect), it will be difficult for him to understand distance, and he will probably think that the world is two-dimensional.

To put it simply: n-dimension is the space formed by two perpendicular pairs of n straight lines.

Because, humans can only understand dimensions, so the later dimensions can be constructed by mathematical theories, but it is difficult to understand them carefully. in quantum mechanics.

The membrane theory, which is still being established, holds that the universe is 11 dimensions. Target.

In fact, I personally believe that there are, and at the same time there are different people-history-events in different spaces.

Does Four-Dimensional Space Really Exist? What impact will it have on the real world? After reading it, my back sweated.

Uh, it seems that the most confirmative thing is 3 dimensions.

Humans live in three-dimensional space.

Three-dimensional space, which can be referred to in daily life, is composed of three dimensions: length, width and height, which is a space that we can see and feel. Three-dimensional things are capable of accommodating two-dimensional. The three axes of length, width, and height in three-dimensional space are to explain the distance relationship between objects in three-dimensional space relative to the origin o.

Press some rubber ropes to the warp and weft lines.

The style is woven into a net and flattened.

We can think of it as a two-dimensional plane, and then we put a small ball on the net, and the rubber net is concave under the gravity of the ball, which forms a three-dimensional space.

Three-dimensional space withFour-dimensional spaceof contact

Four-dimensional space is a concept of space-time. To put it simply, any space with four dimensions can be called a "four-dimensional space". However, most of the "four-dimensional space" mentioned in daily life refers to Einstein.

In his book General Relativity.

and Special Relativity.

The "four-dimensional space-time" mentioned in .

According to Einstein's concept, our universe is made up of time and space. The relationship between time and space is that there is an additional time axis in the structure of space compared with the three axes of length, width and height of ordinary three-dimensional space, and this time axis is an axis of imaginary values.

Human beings live in a four-dimensional space, and there is time, for example, you can add a time to determine the length, width and height of a place.

We live inThree-dimensional spaceThree-dimensional space is characterized by its length, width, and height, which can be measured and positioned. But the human eye can only see the two-dimensional surface, and the so-called distance is just a habitual judgment made by people in the brain based on the dark contrast. But human thinking can break through the limitations of three-dimensional space, relying on geometric imagination and mathematical compilation.

reasoning, you can deduce multi-dimensionality.

Three-dimensional spatial narrationThe 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.

In addition to one-dimensional space, two-dimensional space, and three-dimensional space, there is also a four-dimensional space that refers to time.

One-dimensional space is a line with only length.

A two-dimensional space consists of an infinite number of one-dimensional spaces that make up a single face.

Three-dimensional space is a three-dimensional space composed of countless two-dimensional spaces. Time is often regarded as the fourth dimension on the Internet or in film and television dramas, but I don't think so, because time exists in one-dimensional, two-dimensional and three-dimensional, and it cannot be separated as a separate dimension.

The so-called four-dimensional is logically formed by the combination of countless three-dimensional spaces, but it is difficult to imagine what countless three-dimensional spaces can be formed into with our existing cognition. You can imagine a two-dimensional cartoon that we watch, we can see that they are moving on a plane, but they don't know and don't know what the three-dimensional space we are in is like, just as we don't know what the four-dimensional space is like, maybe the creatures in the four-dimensional space are watching our movement in the three-dimensional Li Chenqin.

So I think that the dimensions we live in are the three dimensions that we can perceive, and when we break through the cognition and see what the four dimensions look like, we cross the dimensions, and then we can say that we live in the four dimensions, the fifth dimension, the six dimensions.

Three-dimensional space in daily life refers to the space composed of three dimensions: length, width and height, which is a space that people can see and feel. Moreover, objects in three-dimensional space can accommodate objects in two-dimensional space.

Dimensions in 3D space represent directions. A pattern of straight lines established by one direction is a one-dimensional space, and dimensional space is unidirectional. The planar pattern established by the two directions is a two-dimensional space, and the two-dimensional space has a bidirectional nature.

In the same way, three-dimensional space is three-dimensional, three-directional, and established by the infinite extension of three directions.
