Family network realizes its dream of inheriting culture by recording life, culture and history. The launched timeline product is the basis for officially realizing the dream. If you want to inherit, you must first have a complete record of the system. Timeline is to classify and sort things according to cultural classification and time, and present them to users in the most appropriate form. Let time and space no longer be our obstacles, as long as a line, we can go back to the past.

According to Einstein's theory of relativity, the three-dimensional space we face in our life plus time constitutes the so-called four-dimensional space. Because the time we feel on the earth is very slow, we won't obviously feel the existence of four-dimensional space, but once we board the spacecraft or reach the universe, when our reference system starts to get faster or close to the speed of light, we can find the change of time by comparison. If you sail in a spaceship with a speed close to the speed of light, your life will be much longer than that of the people on earth. There is a potential field here, and the energy of matter will change with the change of speed. So the change and contrast of time is based on the speed of matter. This is why time is one of the elements of four-dimensional space.

We can consider it from two dimensions:

A two-dimensional creature (if any) thinks that the so-called three-dimensional space is absolutely different from our three-dimensional space-they will regard time as the third dimension because they can't feel the existence of this dimension.

Similarly, we have now entered this misunderstanding and counted time as the third dimension. Maybe the four-dimensional creatures are sighing for us when they see us preaching this idea.

So time is one-dimensional? In my opinion, time should be one-dimensional, that is, adding a dimension to the dimension of multi-dimensional creatures to form a new N+ 1 dimensional space, which is higher than the three-dimensional space, will also help us solve some problems and deepen our understanding.

Time can be decomposed, which may be a bit difficult to understand. However, as long as you figure it out, it is very simple. To understand this truth, we must first understand two points:

The first is the inseparability of time and space. It is estimated that everyone understands that it is meaningless to talk about time without space.

The second point is the diversity of time, which may be a bit troublesome to understand. In our daily life, we are all exposed to the synthesis of time, that is, a total time system composed of various time points. Maybe you think I'm picky, but I'm not. Just think about it from another angle, a result may be formed by several different reasons. Taking sports as an example, we generally observe the combination of several different sports, that is, combined sports.

Part of time corresponds to a space. In this incomplete space, time plays a decisive role. We are three-dimensional creatures because there is only three-dimensional time in this dimensional space.

The incompleteness of time determines the incompleteness of space. We can't know the other dimensions of space because we don't have time to move in that space. The diversity of time determines the diversity of space.

At the same time, due to the different decomposition methods of time, our three-dimensional space is destined to be relative, and it can be named one-dimensional, two-dimensional, or even arbitrary-it depends entirely on different decomposition methods.

Time is the key to determine the dimension, and it is also the key to determine the existence of high dimensions of low-dimensional objects.

Using time to explain any latitude space, we can also think that the reason why low dimensions are lower than high dimensions is that they have time defects and cannot feel the existence of high dimensions in time. Therefore, to understand low-dimensional or high-dimensional, we must first know the time range of their existence.

The conversion between high dimension and low dimension can be realized. The reason is simple, just add or delete a time unit. However, it is easier said than done. Our concept of time is so vague that it is more difficult to realize the transformation of time in space.

For four-dimensional space, most people may just think that there is a time axis on the axis of length, width and height, but most people still know little about it.

Now we who live in three-dimensional space interfere with it. We just need to take the two-dimensional person out of the circle from the third direction (that is, the direction in which the heel axis indicates the height) and put it back to other places in the two-dimensional space.

For us three-dimensional people, the situation in four-dimensional space is very similar to the above explanation. If we can overcome the four-dimensional space, it is not impossible to cross the distance of three-dimensional space in an instant.

Relevant information is also the understanding of four-dimensional space by legal theory!

Four-dimensional space is just a movie for human beings. Multidimensional space. I don't want to say anything. I only say four-dimensional space now! In the field of science, four-dimensional space is considered to be a combination of time axis and three-dimensional space. It is suggested that we can see the past and future through the time axis-I had something to say here, but I put it behind for the sake of fluency-but some scholars associate four-dimensional space with black holes and think that four-dimensional space can let us go back to the past or enter the future. Before talking about the past and the future, let me talk about the uniqueness of the world. Both cosmology and astrology now recognize dark matter and dark energy, and put forward the concept of multiverse. And what I want to say is our universe, not similar universes in many universes. When pointing out our unique universe, let's talk about our past and future. I won't say whether four-dimensional space (that is, the concept of time axis) can take us to the past or the future. What I want to say is, when I go back to the past or enter the future, when that urging behavior becomes a reality, is it still ours? First: Going back to the past, is their history still our present history? Will their behavior have an impact on historical production? If it succeeds, then their history will not be our history today. If not, then is their behavior really going back to the past? On the other hand, that is to say, after they return to the past, do they have substantial body and quality? If there is such a historical change, it is absolutely true. If not, their behavior does not constitute going back to the past-I emphasize again that if we can really go back to the past, it can only be said in the multiverse, that is, going back to a similar historical past, not our present past. Now we talk about entering the future, if we can enter the future through the timeline. So is the future still the future? I'm not arguing about our future like this. What I want to say is that if we enter the future-for a simpler explanation, we won't say that we have entered the future, but that we have seen the future-will the future develop exactly the same? If you see yourself in a disaster two days later, can you make it happen again? Even if you can repeat it completely, is your mentality still what you saw two days ago? If a lie is discovered by humans three days later, then someone saw it four days ago. Can this behavior still be established? If one of so many decisive factors changes, can that universe or world still be ours?

In this way, our universe or world is built on this unchangeable form, so isn't the four-dimensional space a movie for us? (Of course, the keynote of this statement is that it has denied that four-dimensional space can take us to the past or the future. ) Now people will see if four-dimensional space can take us back to the past or the future. Zero-dimensional space is defined as points, one-dimensional space is defined as length (composed of points), and two-dimensional space is defined as width (composed of length and width)-that is, plane. I just want to tell you this in the local dialect, but don't misunderstand-three dimensions.
