The human brain cannot be said to be four-dimensional or multi-dimensional, it should be said whether the consciousness produced by the human brain is four-dimensional, and it cannot be simply said to be four-dimensional or five-dimensional, which is only the hypothetical hypothesis put forward by science for supernatural problems or the theoretical physics in order to solve some physical problems The four-dimensional space is a concept of time and space. 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 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 Einstein's theory of relativity, the three-dimensional space we face in our lives plus time constitutes the so-called four-dimensional space. Since the time we perceive on Earth is very slow, we will not obviously feel the existence of four-dimensional space, but once we board a spaceship or reach the universe, we can find the change in time when the speed of our reference frame begins to speed up or begins to approach the speed of light.
If you sail in a spaceship that is close to the speed of light, you will live a lot longer than a person on Earth. There is a potential here where the energy of matter changes with speed. Therefore, the change and contrast of time is based on the speed of matter.
This is one of the elements of what time is in four-dimensional space.
In the special theory of relativity, time and space constitute an inseparable whole – four-dimensional space-time, and energy and momentum also constitute an inseparable whole – four-dimensional momentum. This suggests that there may be a deep connection between some seemingly unrelated quantities in nature. In the future discussion of general relativity, we will also see that there is a deep connection between space-time and the four vectors of energy momentum.

The floor plan is two-dimensional, the three-dimensional view is three-dimensional, and the four-dimensional view is three-dimensional**. Of course, the fifth and sixth dimensions are to add a few more angles to see the drops!
Four-dimensional, you can imagine, for example, when you look at the object with both eyes, one eye can be seen at level with your eyes, but the other eye can be seen at a relative side angle, so that a three-dimensional sense is formed, because the thickness of the object is checked from the side, which is the effect of the other eye can see the thickness of the side. Of course, if you are far away from the object, it is difficult to see the thickness of the object, so we only treat it as a flat view, that is, two-dimensional. And the four-dimensional just mentioned, when you look at the eyes can distinguish the three-dimensional diagram of the near place, if you add another eye, you can see the four-dimensional.
This is important in the computer in the future, because the computer can have multiple video capture windows, so that the computer can see things more clearly (per unit of time) than we can see.
Since human beings have never had a four-dimensional image, but you can borrow computer technology to ** four-dimensional image, but your brain will hurt a lot, because it is difficult to analyze it clearly in the brain. If you borrow a three-D game video, you can change the angle at will! Of course, it's not difficult to see clearly, but at the same time, if you want to see three dimensions and one dimension clearly, your brain will be bigger.
Four-dimensional space-time. There are various multidimensional spaces in mathematics, but so far, the physical world we know is only four-dimensional, that is, three-dimensional space plus one-dimensional time. The high-dimensional space mentioned in modern microscopic physics is another meaning, which has only mathematical significance. >>>More
During the 22nd to 26th week of pregnancy, you need to do a four-dimensional color ultrasound examination, which can screen the health status of the fetus and whether there are malformations. After this time, you will not be able to do this kind of screening program.
Yes, the universe is four-dimensional, but three dimensions are space and the other is time. Therefore, it cannot be said that "the universe is a four-dimensional space". >>>More
The so-called high-dimensional space is relative to the three-dimensional space in which human beings live or can come into contact with the lower-dimensional space, and human beings exercise the existing superficial common sense to distinguish different dimensional spaces for the worldThere are four dimensions of space, namely zero-dimensional space, one-dimensional space, two-dimensional space, and three-dimensional space. >>>More
Human beings currently live in three-dimensional space, and if they accidentally enter the four-dimensional space, then they should change their form, because from the zero-dimensional space to the four-dimensional space, the form will change every time one dimension is raised. It should also be possible to travel through the past and the future, or stay in any one period of time at will, rather than having to move towards the fixed direction of time and develop towards the future like three-dimensional space.
