Chapter 112: Essence of time

Seeing that Hawking's breathing improved, Elaine stood silently to the side, not even daring to intervene, not even daring to breathe.
She doesn't know what to change history, or to make history.
Elaine only knew that she must be witnessing history.
Hawking thought for a moment, did not understand the meaning of Huang Ji's words, history cannot be changed, only creation? He didn't want to hear such vague answers.
I saw him ask: "Are you really a time traveler? I can't believe it now. When I saw that invitation letter, I felt that the world I had understood in my life was collapsing."
Huang Ji was noncommittal and did not speak.
Hawking said: "I will not issue an invitation letter, I can tell you very firmly, I will definitely not issue an invitation letter!"
"Please don't say that you will send the invitation letter instead of me. You should understand that I am asking a question equivalent to the grandmother's paradox. Please tell me, why can you come to my party?"
Huang Ji inserted another orange to eat, and smiled: "Professor Hawking, as a scientist, you should understand that paradoxes will not happen."
"When you think something is a paradox, there must be some misunderstanding here."
Hawking asked, "Please tell me, what is the misunderstanding? Since you are here at my party, you are sure to satisfy my curiosity, right?"
Huang Ji said, "Of course, Professor, I will also benefit from you."
"Okay." Hawking agreed without hesitation.
He doesn't care what Huang Ji needs, even life doesn't matter. He was sentenced to death by a doctor a long time ago. It was curiosity about the universe that drove him to live today.
Huang Ji said: "If A goes back in time and kills his grandmother before his mother is born, people will take it for granted that this action will create contradictions, so that A will not be born and will not kill her grandmother through time and space. "
"This is the grandmother's paradox proposed by Henet. It is widely spread and very classic. It also represents the arrogance of human beings about time."
"In the story of the grandmother's paradox, it is forcibly set that'A is a person whose grandmother was not killed but was born normally'. At the beginning of the logic, a history of'the grandmother is alive' is implanted in people. This premise, It is clearly assumed."
"After first arranging a'normal history', it assumed a history of killing grandmother through time and space, creating a B history."
"In the following story, the history of A and the history of B are put together and compared as a'simultaneous' event, saying that this is a contradiction. Isn't this nonsense?"
"Alexander's conquest of Egypt is a kind of history. He did not conquer Egypt, and it is also a possibility of history. Two historical possibilities, as long as they proceed at the same time, are naturally contradictory."
"The whole paradox is that one person has participated in two histories one after another, but misleading people to think that'it should happen at the same time' is a secret exchange of concepts."
"This is a typical logical misunderstanding, a paradox created by man."
Hawking tilted his neck and said, "This is a thought experiment. Of course, there are presuppositions. This person has traveled to the past and participated in the past. Of course, he belongs to two kinds of history at the same time."
Huang Ji said: "This is a misunderstanding. Professor Hawking."
"The reason why the concept is secretly changed without making people feel inconsistent is because there is a setting of'time travel' in the middle."
"People actually don't know anything about going back in time, so you instinctively feel that it is reasonable to participate in both types of history at the same time."
Seeing that Hawking hadn't figured it out by himself, Huang Ji smiled and said: "A phenomenon must have its truth. When people think that something is a paradox, it must be that something inside has been misunderstood."
Hawking agrees with this point, which is the cornerstone of science.
One thing is a paradox, either a certain concept is not added, or a certain concept inside is wrong.
Therefore, there are two main explanations for the grandmother's paradox. One is Hawking's time sequence protection conjecture: time travel is not allowed at all.
The second is the famous parallel world theory. The moment a person crosses, he arrives in a whole new world. It is not his grandmother who kills his grandmother, but the same'other self' grandmother.
"So... you mean the parallel world? You are already standing in front of me, and there is no paradox, so you are from another parallel universe? Am I wrong..." Hawking said.
He does not support parallel worlds. He believes that time travel does not exist in order to protect the paradox from happening.
Now Huang Ji was standing in front of him. He could only think that Huang Ji came from a parallel world.
Unexpectedly, Huang Ji shook his head and said, "No, you are actually right. Your theory is closer to the truth, Professor Hawking. Time travel will not split parallel worlds."
Hawking's eyes jerked, surprised.
what? Not parallel world theory? Timing protection is closer to the truth?
how is this possible? In other words, what the time traveler travels through is the past of his own world? Doesn't this still have to face the grandmother's paradox?
Huang Ji explained: "The false premise of the grandmother's paradox is that time travellers can enter the past history... and then return to the original history."
"This is the biggest misunderstanding of people: treat time as space."
"People cannot perceive time, as if they cannot perceive higher dimensions, so they can only guess what it looks like by analogy."
"Because people can move forward and backward in space, they assume that once they master time, they should and can move forward and backward in time."
"This has caused everyone to understand time as a path, and time travel as a way back to the beginning after going back to the past."
"Finally, I depressedly contrasted the'world before I change' with the'world after the change'. Isn't this nonsense?"
Hawking said: "You mean, after going back in time, you can't go back again?"
"What about the original world?"
Huang Ji smiled and said, "Look, you are imagining the original world again."
"The reason why people feel the paradox is because they forcibly join a world that does not exist."
"Time is misunderstood. It should not be compared with space, but with'light'."
"The light... is reflected back, do you think the light is flowing backwards? It just changed direction."
Hawking was silent, and then asked: "So what is the essence of time?"
Huang Ji said: "The essence of time, you can imagine it as a substance."
"It's not that all things move forward in time, but time is born one by one in all things. Time is not space, it is not a road."
"Time also has the nature of particles. It is absorbed by everything, just like light quanta. This absorption itself does not consume time, but is actually the intrinsic property of matter."
"It's like quantum fluctuations, appearing instantly, and then being consumed instantly."
"All things include space. They absorb time, and they can change themselves, and they can only absorb but not emit. Just like entropy increase, it has only one direction. The consumed'time entropy' will only increase, not decrease. ."
"If matter doesn't absorb time anymore, it will stay still. Isn't it a bit similar to energy? Time is a kind of'fuel', but it belongs to'energy that drives things to change'."
"Energy is only a condition that drives the change of matter. Light has energy, but without time, everything will not change, space will not expand, and energy will remain static. The world that does not change is meaningless."
"The more time everything absorbs, the faster it changes. Conversely, the slower time. This is related to quality. The greater the distortion of space, the lower the rate of time absorption. The most efficient is undoubtedly zero mass. The rate at which an object absorbs time in a vacuum."
Elaine heard Yunshan misty, her face stunned.
Hawking was stunned. Huang Ji directly regarded time as matter and energy, and space as matter, and finally unified them together, and proposed the concept of time entropy, which fits reality and preserves thermodynamics. The second law.
Relativity and quantum mechanics are two buildings of human physics, but they are incompatible with each other. The biggest contradiction is the understanding of time and space.
People have been looking for theories to unify them, and then something like string theory has appeared, and high-dimensional conjectures have to be added.
However, Huang Ji took a different approach. It directly regarded time as a quantum fluctuation-like substance, born piece by piece. It has no mass or force, so it cannot be observed.
The only thing that proves its existence is the slow time of massive objects.
Huang Ji has made relativity and quantum mechanics compatible.
"This is amazing, can you prove it? Can you deduce it by mathematical description?" Hawking said eagerly.
However, Huang Ji calmly said: "I'm sorry, Professor Hawking, the proof process is too long, I can't write it here!"
"#@￥#@#@……￥#@!" Hawking had a language barrier again, unable to send a full sentence for a long time.
He knew that this was not just a problem that could not be written, his limited life might not be able to read the Universe Model.
"So the essence of time travel is not to leap over to the past on the time axis, but... to discharge time?" Hawking slowly calmed his mood, and immediately deduced the time-reverse method based on Huang Ji's theory.
Huang Ji said: "Yes, this is a theoretically time-reversed method. Just as life is a low-entropy body that can emit entropy in the body, this is actually aggravating the overall entropy increase in the universe."
"Emission time is the same. Normally, emissions are not possible, but in theory, technology can be used to achieve'time emission'. One emission must lead to the other. Emission time itself also consumes time, and the total time of the universe The quantity is finite, so it will eventually lead to...'time silence', time entropy increases to the limit."
Hawking was surprised: "Time is... is it limited?"
Huang Ji said: "This is the biggest misunderstanding that people have about time. The total amount of time is limited. This is cruel, but it is true."
"The total amount of matter in the universe is limited, energy is limited, and space is limited. Why is time infinite?"
"Physicists are committed to unifying time, space, energy, and matter, and they all regard them as the'same thing'. They are essentially the same thing."
Hawking is silent. If a unified theory is to be established, then these four things are actually different manifestations of the same thing.
Huang Ji continued: "Absorption and emission are both consuming time, but emission is doubling. So Dr. Hawking, your theoretical thinking is correct,'time is irreversible', but the universe can return to its past state. It's not a contradiction."
"If an object stops absorbing time, then time is still. No matter how you attack it, it will not have any physical reaction or chemical change with it. No, you can't even see it! Because it doesn't emit light or participate in it. Electromagnetic interaction."
"In the universe, apart from fixing the originally distorted space-time, which is the gravitational field, it doesn't even know it exists."
"If it accelerates absorption, then time accelerates. Shroud the entire earth in the time acceleration field, and you will see a rapidly developing earth..."
"On the other hand, if a person wants to rejuvenate, he only needs to spend his own time, and everything in the position and state of matter will flow backward."
"If you want to go back to the past, you can release the entire space and all the materials inside."
Hawking understood. In this way, the grandmother's paradox would not be contradictory.
Suppose that the time that A emits all the matter in the universe, for example, 50 years, then he goes back to 50 years ago.
He killed his grandmother, but this will not lead to his disappearance, because as early as when he went back in time, he had already'killed' his mother, and he erased everything that was born in the past fifty years. Rewind all particles to their past state.
A Back to 50 years ago, it belonged to the "island in the long river of time", and it will not be back 50 years later. Time is irreversible, history is history, and the past is the past.
He just let everything, change direction, start over.
"Returning time will not change history, but create history..." Hawking remembered what Huang Ji said at the beginning.
This conjecture is too amazing... No, this is not a conjecture, the other party is a time traveler, what he said is... fact?
"You irreversibly flow back the time of the entire universe in order to come back to see me?" Hawking said in horror.
Huang Ji smiled and said: "It has nothing to do with you. UU reading www.uukanshu.com"
Hawking was not surprised. The other party could not change the world just for him. There must be other reasons. It was incidental to see himself.
This is simply unimaginable technology! How much damage is this to the universe?
The most frightening thing is that those who are in it will not know that time has gone backwards, let alone find any traces.
"Unbelievable, how many years has the universe regressed? Has mankind ruled the entire universe in the future? How many years of development has been a terrifying technology?" Hawking was completely confused.
Unexpectedly, Huang Ji said, "This has nothing to do with humans."
Hawking is stunned, has nothing to do with humans? What does this mean?
Huang Ji's next sentence completely stunned him and Elaine.
"Professor Hawking, I never said...I am a human being."
