In a special time and space, Fang Yun and his past self stood in front of Wen Renxue at the same time, and a special multiple-choice question was also placed in front of Wen Renxue.
Choose the past or choose the present.
If you choose to stay in Wushi, you will be accompanied by young Fang Yun.
If you choose Young Emperor Fang Yun, you need to follow Fang Yun and return to the family.
Wen Renxue was at a loss. For a moment, she didn't know how to make a decision.
On the one hand, she really hoped that she could stay in Wushi and get along with young Fang Yun day and night, but on the other hand, she couldn't let go of her family or the young emperor. After all, that was the current Fang Yun.
Wen Renxue has a hard time making a decision.
The two Fang Yuns stood opposite each other, both carrying awe-inspiring auras, but they did not force her, letting her think slowly.
It was at this moment that Fang Yun entered a special time and space and found Wen Renxue.
In the Star Network, in the Chinese Immortal Realm, without any warning, a great debate broke out on a topic, the relationship between the past and the present.
The topic of this debate is mainly the comparison between the past and the present.
You can compare and debate who is better in the past or now.
You can compare and argue about who is more important, past or present.
You can also compare and argue, who is related to the past and present, and which one is the main position.
This debate originated from a special debate competition in Yuncheng Yunyuan.
In this debate competition, Yuncheng Academy of Philosophy, two major teams and three debaters, were broadcast live on the entire network and debated live.
Its excellent style, classic debates, and the superb appearance of several debaters immediately aroused heated discussions on the entire Internet.
With the rise of the Chinese Immortal Realm, Chinese culture has set off a tornado.
The wind of debate blowing from the Chinese Immortal Realm suddenly swept the entire Internet.
Major colleges and universities rushed to imitate it and organized debate competitions one after another, aiming to make the relationship between the past and the future clear and clear.
In the beginning, the great debate about the relationship between past and present was just a philosophical debate.
Later, as more people joined, and as more scholars joined, this topic became more and more profound.
In the end, it turned into an academic issue.
Within Yuncheng Yunyuan, someone raised a brand new topic, the question of how to define the past, present and future.
Also, if there is no complete definition, how can you argue?
If you want to debate, you must first identify the subject of the debate, right?
As a result, academic circles also joined the debate.
Scholars from different disciplines have different standards for defining the past, present and future.
Then, after scholars in these disciplines published this standard, they immediately organized relevant debate competitions, which became very lively.
However, the self-judgment standards of a single academic discipline cannot yet be recognized by other disciplines, so this big debate suddenly became extremely lively.
Psychologists believe that the past, present and future are the psychological behaviors of intelligent creatures and a judgment on the state of things.
Therefore, the criteria for distinguishing the past, present and future are completely different for different intelligent individuals, and among them, the most important criterion should be two words, feeling.
When intelligent creatures feel that it is the past, that is the past; when intelligent creatures feel that this is still the present, it is now; when intelligent creatures think that something is about to happen, that is the future.
At first glance, the psychologist's judgment standard seems to be almost non-standard. However, he listed a Versailles formula to judge the past, present and future.
The Versailles formula is very complicated, but psychologists simply describe it in two sentences: the square of the time required to complete a thing minus one percent of the resources required to complete the thing, divided by all
The manpower required will ultimately be the Versailles Index. When the Versailles Index is greater than one, it means that this matter has passed and is in the past tense. When the Versailles Index is still less than one, it means that this matter is still present.
This Versailles formula is quite complicated, especially the resource part and the manpower part, which require the use of many other calculation formulas. Overall, it is a tall formula.
Just like psychologists are always mysterious, the Versailles formula is also extremely mysterious.
It must be quite troublesome for ordinary people to use this thing to judge the past and present.
Therefore, historians sneer at this method of judgment by psychologists.
Historians believe that it could not be easier to judge the past and present, just based on the chronology.
There is no need to consider the development process of things. The past, present and future are only related to time and have nothing to do with the event.
Historians have given a very simple and crude standard: within a year, it is the present, and a year ago, it is the past.
The reason is also simple and crude, because historians compile history in units of years, and every year, historians publish an annual record.
As soon as the annual record is published, it means that it is a done deal, history is finalized, and it is a thing of the past.
It should be said that this method of historians is extremely accepted by the general public because it is simple, direct, and clear.
Of course, different planets have very different ways of counting time.
For example, in the Chinese Immortal Realm, there are currently nearly six thousand civilizations and countless planets.
On different planets, the span length of a year is different.
Taking the earth and the Sangqing Sacred Star as an example, two earth years are equivalent to one Sangqing Sacred Star year.
However, because the earth is the main star of the Chinese Immortal Territory, each planet in the entire Chinese Immortal Territory actually has three sets of chronology methods. One is the calendar common to Tiantima; the other is the earth chronology method of the Chinese Immortal Territory;
There is another method, which is the method of counting the years in this star.
These three systems of chronology are called the Great Ephemeris, the Immortal Ephemeris and the Local Ephemeris respectively.
Usually, for a fairy domain, if it is an internal communication of interstellar things, it will use the fairy star calendar; if it communicates with civilizations outside the fairy domain, it will use the large star calendar; but if it is business dealings within its own planet,
, then most people will use this ephemeris.
Of course, after becoming an immortal realm or an immortal star, you will also have many privileges.
Among them, there is one point. When the fairy star communicates with other planets, if the other party is not a fairy star, then the fairy star calendar must be used.
This is the privilege of Fairy Star.
If the opponent is also a fairy star and the status of both parties is equal, then the large ephemeris should be used.
Historians combined the ephemeris to give a definition of the past, present and future, which is simple and practical and has been widely recognized.
However, in the academic world, there are still different voices.
In addition to psychologists, physicists also expressed dissatisfaction with this crude approach by historians.
Physicists believe that time has a direction, and time and space are the ultimate mysteries of physics. Therefore, physicists have the most say about the past, present and future.
Physicists did not come up with any Versailles formula, but they gave physical standards for judging the past, present and future.
And there is more than one standard.
First of all, the standards given by physicists are thermodynamic standards.
Physicists believe that time has an arrow that always points forward. At the same time, physicists believe that time is a way of movement, and in this universe, movement is the eternal theme, and stillness is relative.
Therefore, an important criterion for judging the past and present is entropy increase.
When the entropy increase reaches a certain range and a special situation occurs, it means that the movement of thermal energy has come to an end, so it will become a thing of the past.
Physicists gave a simple example. If two iron balls are thrown from upstairs, the two iron balls will generate kinetic energy at the same time, a kind of energy. From the time when the iron balls are thrown to the flight of the iron balls,
The process is all now.
However, when the iron ball hits the ground and the entropy increase reaches a special peak, the entire process of throwing the iron ball becomes a thing of the past.
This is a concept in physics, and it is also an important criterion for physics to determine the past and present.
The second criterion for physics to determine the past and present is quantum entanglement.
Physicists believe that quantum entanglement is everywhere in this universe, so if quantum entanglement can be used to define the past and present, that would be the most standard.
This definition is also very simple. Two quanta exert a force on each other and become entangled.
Before the entanglement is completed, it is now; after the entanglement is completed, it becomes the past.
