Preface: If it weren't for long-term perseverance and persistence, this article might not be possible. This is more brain-burning than writing the most brain-burning part in " Tianmu Hongchen ".
It turns out that enthusiasm is exhausted like this, haha.
First of all, let me declare:
time exists, and time is generated as long as there is movement. And time and space are one.
A static universe does not need the concept of "time", which does not mean that time does not exist. Just because low-dimensional people do not need the high-dimensional world, it does not mean that the high-dimensional world does not exist.
Time is the subdivision of the sun, and space is the feeling of the five senses.
General Relativity states that the essence of space is matter (because matter is a small space).
The essence of time is movement. Because matter changes, that is, it moves, it produces sequence and cause and effect. That is to say, the essence of time is the movement of matter (space), so there is Einstein's theory of time relativity, because matter has relative motion .
Since the essence of time is the movement of matter (space), the following is easy to understand:
Time and space are one and inseparable, that is, space and time are one.
With the above foundation, let’s understand the following.
"There is a new concept, that is, all dimensions are composed of time. Without time, there is no space, including the most basic one-dimensional space . This should be easy to understand, because without time, the existence of space itself would not exist. In any sense, because space and time itself is an indivisible whole. So, why can one kind of time form different dimensional spaces? Here, we can understand this sentence by treating time as a decomposable constant. It may be a bit difficult. However, it is very simple as long as you figure it out. To understand this truth, you must first understand two points. The first is the inseparability of space and time. I think everyone knows this. Talking about time without space, or It is meaningless to talk about space without time (because the essence of space is matter, and the essence of time is material movement , so time, space and matter are one)
The second point is the diversity of time. It may be a little troublesome to understand. In daily life, what we come into contact with is the composite of time, which is an overall time system formed by the organic combination of various parts of time. You may think that I am quibbling, but I am not. As long as you think about it from another angle, one result may be caused by several different causes. Take motion as an example. What we observe is generally a combination of several different motions, that is, combined motion. .
We can also think about time in this way. The time combination we see can be composed of the time of object movement, historical time (that is, experience time), and we can also look at motion time. It consists of the time of up and down movement, the time of left and right movement and the time of forward and backward movement. Of course, the division methods are diverse, which constitutes the diversity of time. As for how to divide it, it depends on different situations. Time corresponds to a period of space. In this incomplete space, time plays a decisive role.
The reason why we are three-dimensional creatures is that the incompleteness of time determines the incompleteness of space. Complete (for example, we cannot see dark matter , the essence of space is matter). We cannot understand other dimensions of space because we do not have the diversity of space determined by the diversity of time in that space.
At the same time, because of the different decomposition methods of time, our three-dimensional space is destined to be relative, because we ourselves have limitations.
Time is the key to determining the dimension. At the same time, it also determines the way low-dimensional objects exist in high dimensions. Key.
(Note: holographic theory has proven that low-dimensional objects do belong to high dimensions. According to holographic theory, n➖1-dimensional space-time is a projection of n-dimensional space-time.For example, the three-dimensional world is the projection of the four-dimensional world. Since it is a projection, obviously the high-dimensional space includes the low-dimensional space)
So, how do we distinguish between high and low dimensions? It's very simple. Use time (because space is too complex)
to use time to explain any dimensional space. We can also think that the reason why low dimensions are inferior to high dimensions is because they have time defects and they cannot be within the scope of time. Feel the existence of higher dimensions. Therefore, if we want to understand low or high dimensions, we must first know the time range in which they exist. Conversion can be achieved between high and low dimensions. The reason is very simple. Just add or remove an time unit . However, it is easy to say but very complicated to do. How to realize the transformation of time within the spatial scope is a problem.
Now that we know that the essence of time is the movement of matter and that space and time are integrated, now we have to give up our inherent views on time. Time will not only flow in the things around us, but also flow in our bodies. Time only exists inside matter in the form of a rate of change, and the flow rate of time depends to a large extent on the relative motion of matter.
It is undeniable that time is definitely an extremely important basic physical variable in the laws of the universe. The time dilation effect seems inconsistent with our daily cognition, but scientific experiments have proven that this effect does exist. In 1971, scientists placed high-precision cesium atomic clocks on planes flying eastward and westward around the earth. The results proved that the time dilation effect of the clocks was completely consistent with the predictions of 's special theory of relativity.
From this point of view, each of us’ time (individual time attributes) is unique and different. Sometimes it is fast, sometimes it is slow, depending on the interaction between us and various external systems. But under normal circumstances, this time gap is so slight that it is almost imperceptible. "(Quote)
Time is not a tool, but the truth of everything. Before the fourth dimension , it was just parameterized.
We have three dimensions of time in three dimensions, and the fourth dimension of time in the fourth dimension. is the fifth dimension. has five dimensions of time, and so on.
Let’s first talk about zero dimension to six dimensions. Since Einstein talked about the unity of space and time, we cannot say that the four dimensions are three dimensions plus time, because time and Space is indivisible.
(Please also pay attention to the difference between "four-dimensional space" and " four-dimensional space-time ". Four-dimensional space refers to the purely geometric four-dimensional space (I personally believe that in reality, four-dimensional space does not exist), Four-dimensional space-time refers to time ➕ space. In fact, we are in four-dimensional space-time, but our understanding of time is three-dimensional, so the correct statement is that we are between three dimensions and four dimensions, but strictly speaking, we are still in three dimensions. )
. string theory physics knowledge (refer to "Teacher Shang's Design School"), zero dimension is a point, one dimension is a line, two dimensions is the plane formed by the intersection of two lines, and three dimensions is bending the two-dimensional space so that point A is When point B coincides, a three-dimensional space is obtained (curling creates new dimensions!). Because only by expressing it in this way can we advance to higher dimensions.
Time in one dimension, two dimensions, and three dimensions can be approximately understood as linear, and time keeps moving forward evenly (this is just a human illusion).
We often say "as time goes by", which actually means moving forward along the timeline. This timeline is the line in the four-dimensional space. In other words, in three dimensions, we move forward along the timeline in the four-dimensional space-time. Go forward.
But in the fourth dimension, humans can no longer use time as a parameter, because people have cracked the concept of partial time. Assuming that we are four-dimensional space creatures, we can see ourselves at various times in the past, present, and future. That is to say, four-dimensional people can see three-dimensional people, just like us three-dimensional people directly watching two-dimensional people on TV, they can directly drag the time progress bar on the TV (this is also a dimensionality reduction attack).
Therefore, fourth-dimensional people can completely foresee and know their complete life, so they can adjust at any time in order to make better life adjustments.
So the four-dimensional people completely grasp a timeline, that is, our past, present and future at this moment.
So let’s reorganize our thinking. One dimension is a line, two dimensions is a plane formed by the intersection of two lines, and three dimensions is formed by bending the two-dimensional plane so that point A and point B coincide. As shown below, the graph below forms three dimensions. (Similarly, four-dimensional, five-dimensional and six-dimensional people can also use two timelines to intersect to draw a picture similar to the one below)
(Note: People in three-dimensional space can only see the current time, while people in four-dimensional space can see this The complete current timeline, past, present and future)
Since the 0 dimension is just a point, using analogy we might as well regard the me at this moment (that is, the current me) as a point, and the "past me" as a point. form a point, and these two points are connected to form a line, which is the four-dimensional space-time.
When these two points (i.e. past and present) are connected, they will naturally extend into the future, so four-dimensional people can naturally see the past, present and future. According to the holographic theory, we are just projections of four-dimensional people, so we three-dimensional people can only see the present moment.
Similarly, the fourth dimension is a (current) timeline, and the fifth dimension is the intersection of two timelines (five-dimensional people have mastered countless timelines, analogous to the parallel universe . For example, if I became a chef in junior high school, from There are countless other complete timelines produced at the time point of "Junior High School Me", that is, countless possibilities for me after junior high school). The six-dimensional is to bend the five-dimensional plane so that point A (the past) and point B ( future) formed by coincidence.
How to understand five dimensions? Let’s understand the fifth dimension in another way. Imagine bending a timeline (past, present and future), for example into a right angle (the metaphor is just for your convenience). Imagine bending this timeline (i.e. four dimensions) into a plane (i.e. five dimensions). This is the fifth dimension.
On this plane, assuming that this vertex refers to the present, then one line represents the past and the other line represents the future. You see, this line represents countless possible pasts, and the other line represents countless possible futures, so five-dimensional people can have countless possible present, so five-dimensional people can control and decide the present, but cannot decide the future. .
How to understand six dimensions? You see, since point A (past) coincides with point B (future), it means that the past and future are the same, both are now. This means that in six-dimensional time and space, the past, present and future happen at the same time. Therefore, six-dimensional people can travel through any time at will, that is, they can time travel to the past or the future.
To sort it out, four-dimensional people can see a complete current timeline and their certain future, which is commonly known as destiny. And three-dimensional people are just the projection of the definite timeline of four-dimensional people.
Five-dimensional people can see and foresee all their possible past, present and future, so they have more choices now and can choose their own better future. They can time travel to the past and control the present, but they cannot control the future.
Six-dimensional people have traveled through time in this single universe. They have become the best selves possible under the conditions, and can travel to the future and the past at will. At this moment, perhaps studying other multiverses has become a bigger topic for them. After all, Hawking said in " The Universe in a Nutshell ": The universe we know is either designed, or there must be multiple universes. If the earth was designed, there must be higher dimensional beings.
As for seven dimensions, eight dimensions and nine dimensions, I personally think they involve infinite timelines in the multiverse. There are infinite dimensions in the universe, but starting from the ninth dimension, it has been shaking, and it has started over again, but at a higher level.
Note: Everything has rules, and so do dimensions.For example, the seventh dimension is an infinite timeline, the eighth dimension is the intersection of two infinite timelines, and and nine dimensions are made by bending the eight dimensions so that point A and point B coincide. As shown in the picture above, nine dimensions appeared.
