What does a four dimensional space look like?

According to scientists, the four-dimensional space is an infinite superposition of three-dimensional space, and with the composition of time, the other four-dimensional creatures will know all their own trajectories, and the superstring theory says that the world is made up of 10-dimensional space plus time, and the seven dimensions are curled up on the Planck microscopic scale, and if you enter the four-dimensional space, you will be like a Klein bottle.

Four-dimensional space is a concept of space-time. In simple terms, 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 the concept of "four-dimensional space-time" mentioned by Albert Einstein in his "General Theory of Relativity" and "Special Theory of Relativity".

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 a real value axis.

Determining the space of four coordinates (three coordinates of space and one coordinate of time) is required for everything.

Four-dimensional space is a whole composed of three-dimensional space and time.

The position of any point in three-dimensional space can be determined by three coordinates, in which things are actually relatively stationary, and the space that can accommodate life is at least four-dimensional. It can be said that life is a space substance that can perceive and record time coordinates.

This concept is based on the fact that all matter exists in space and time at the same time, and space and time are inseparable. The geometry of four-dimensional space played an important role in the widespread dissemination of the theory of relativity.

The one-dimensional annihilator is a line, the two-dimensional is a surface, the three-dimensional is a static space, and the four-dimensional is a dynamic space (because of time), of course, this is just a statement, and.

Four-dimensional space. It's not that the fourth dimension is time.

In physics, the parameter that must change to describe a changing event is called dimension. A few parameters are just a few dimensions. For example, the position of a "door" is described only by the angle, so it is one-dimensional rather than two-dimensional.

To put it simply: zero-dimension is a point, 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. The three-dimensional body is composed of countless facets of the mill, 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 four dimensions. Just as a person with normal intelligence and born with only one eye and one ear (so that there is no binocular effect, binaural effect), it is difficult for him to understand distance, and he is likely to think that the world is two-dimensional.

To put it simply: n-dimension is the space formed by two or more n-1 dimensional objects perpendicular.

Because, humans can only understand 3 dimensions, the later dimensions can be constructed by mathematical theories, but it is difficult to understand carefully. In quantum mechanics, string theory, which is still being established, holds that the world is 11 dimensions. (10-dimensional space + 1-dimensional time).
