Chapter 112 Time Essence

Seeing that Hawking's breathing was getting better, Elaine stood there silently, not even daring to breathe.

She doesn't understand what changes history, or what makes history.

Elaine only knew that she must be witnessing history.

Hawking thought for a moment, but 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 still can't believe it. When I saw that invitation, I felt that the world I had understood all 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 that I will 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 you can come to my party?"

Huang Ji ate another orange and said with a smile, "Professor Hawking, as a scientist, you should understand that paradoxes cannot really happen."

"When you think of a thing as a paradox, there must be some kind of misunderstanding here."

Hawking asked: "Please tell me, what is the misunderstanding? Since you came to my party, you must be willing to satisfy my curiosity?"

Huang Ji said: "Of course, Professor, I will also gain something from you."

"Okay." Hawking agreed without hesitation.

He doesn't care what Huang Ji needs, even life doesn't matter. He has been sentenced to death by the doctor long ago. It is his curiosity about the universe that drives him to live to this day.

Huang Ji said: "If A went back to the past and killed his grandmother before his mother was born, people would take it for granted that this action would cause a contradiction, and that A would not be born and would not travel through time and space to kill his grandmother. "

"This is the grandmother's paradox proposed by Henet. It is widely circulated and very classic. It also represents a certain 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'. It was clearly assumed."

"After first arranging a 'normal history',

It also assumed a history of killing the grandmother through time and space, creating a B history. "

"After this story, put A history and B history together and compare them as 'simultaneous' events, saying that this is contradictory. Isn't this nonsense?"

"Alexander's conquest of Egypt is a kind of history. He did not conquer Egypt, but it is also a possibility of history. As long as the two historical possibilities are carried out at the same time, they are naturally contradictory."

"The whole paradox, obviously one person has participated in two histories one after another, but misleads people to think that 'it should happen at the same time' is to steal the concept."

"This is a typical logical error, an artificially created paradox."

Hawking tilted his neck and said, "This is a thought experiment. Of course, there are presuppositions. This person travels to the past and participates in the history of the past. Of course, he belongs to two histories at the same time."

Huang Ji said: "This is a misunderstanding. Professor Hawking."

"The reason why I secretly changed the concept without making people feel inconsistent is because there is a setting of 'time travel' in the middle."

"People don't really know anything about going back in time, so you instinctively feel that it makes sense to be involved in both histories."

Seeing that Hawking hadn't figured it out yet, Huang Ji said with a smile: "When a phenomenon occurs, there must be a reason. When people think that something is a paradox, it must be something inside that has been misunderstood."

Hawking fully agrees with this, which is the cornerstone of science.

One thing is a paradox, either a concept is not added in, or a concept in it is wrong.

Therefore, there are two main explanations for the grandmother paradox. One is Hawking's time series protection conjecture: time travel is not allowed at all.

The second is the famous parallel world theory. When a person travels through the world, he will enter a whole new world, and he will not kill his own grandmother, but the same "other self" grandmother.

"So...you mean a 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, and he believes that time travel does not exist in order to prevent paradoxes from happening.

Now that 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 snapped, startled.

What? Not parallel world theory? Timing protection closer to the truth?

how is this possible? In other words, the time traveler travels through the past of his own world? Isn't this still about the grandmother paradox?

Huang Ji explained: "The grandmother's paradox, the false premise is that time travelers can enter past history...and then go back to the original history."

"That's the biggest misunderstanding people make: Thinking of time as space."

"People can't perceive time, as if they can't perceive higher dimensions, so they can only guess what it looks like by analogy."

"Because people can move forward and backward in space, it is assumed that once they have time, they should also be able to move forward and backward in time."

"This has led everyone to understand time as a road, and time travel as a way to go back to the past and return to the starting point."

"In the end, there was a depressing comparison between 'the world before my change' and the 'world after my change'. Isn't this nonsense?"

Hawking said: "You mean, after going back to the past, you can't go back again?"

"What about the original world?"

Huang Ji smiled and said, "Look, you are imagining the original world again."

"People feel paradoxical because they're forced into a world that doesn't exist."

"Time is misunderstood. It should not be compared to space, but to 'light'."

"The light... is reflected back, do you think the light is flowing backwards? It's just going the other way."

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 is not that all things move forward in time, but time is born one by one on all things. Time is not space, it is not a road."

"Time also has the nature of particles, and a portion, like a quantum of light, is absorbed by all things. This absorption itself does not consume time, but is actually the intrinsic property of matter."

"It's like quantum fluctuations, which appear in an instant and are consumed in an instant."

"Everything includes 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 reabsorb time, it's at rest. Kind of like energy, isn't it? Time is a 'fuel', just the '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. A world that does not change is meaningless."

"The more time everything absorbs, the faster it changes. On the contrary, the slower time. This is related to mass. The greater the space distortion, 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 listened to Yunshan's fog cover, and her face was stunned.

Hawking was stunned. Huang Ji directly regarded time as matter and energy, and regarded space as matter, and finally unified them together, and proposed the concept of time entropy, which conformed to reality while preserving thermodynamics. Second Law.

Relativity and quantum mechanics are two edifices of human physics, but they are incompatible with each other. The biggest contradiction is the understanding of space and time.

The search for a theory to unify them led to things like string theory, which had to add higher-dimensional conjectures.

However, Huang Ji took a different approach. It directly regards time as a matter like quantum fluctuations, and is born one by one. It has no mass and no force, so it is unobservable.

The only proof of its existence is the slow time of massive objects.

Huang Ji made relativity and quantum mechanics compatible.

"It's amazing, can you prove it? Can you deduce it mathematically?" Hawking asked eagerly.

However, Huang Ji said calmly: "I'm sorry, Professor Hawking, the proof process is too big to write here!"

"#x-on:￥#x-on:#x-on:...￥#x-on:!" Hawking had a language barrier again, unable to utter a single word for a long time.

He knew that this was not just a problem that could not be written down. It would be difficult for his limited life to read the Grand Unified Model of the Universe.

"So the essence of time travel is not to travel to the past on the time axis, but to... discharge time?" Hawking slowly calmed down, and immediately deduced the time reversal method based on Huang Ji's theory.

Huang Ji said: "Yes, this is a theoretical way of rewinding time. Just as life is a low-entropy body and can discharge entropy in the body, this is actually aggravating the entropy increase of the universe as a whole."

"The same is true for the discharge time. Normally, it cannot be discharged, but in theory, it is possible to use technology to achieve 'time discharge'. One discharge will inevitably lead to the other. The discharge time itself also consumes time, and the total time of the universe The amount is finite, so it will eventually lead to... 'time silence', where the entropy of time increases to its limit."

Hawking said in shock: "Is time... is it limited?"

Huang Ji said: "People's biggest misunderstanding about time is this. The total amount of time is limited. It's cruel, but it's the truth."

"The total amount of matter in the universe is limited, energy is limited, space is limited, why is time unlimited?"

"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 was silent. If a unified theory is to be established, then these four things are actually different manifestations of the same thing.

Huang Ji continued: "Both absorption and emission consume time, but emission consumes twice as much. So Dr. Hawking, your theoretical thinking is right, 'time is irreversible', but the universe can return to the state of the past, which is It's not really contradictory."

"If an object stops absorbing time, then its time is still, and no matter how you attack it, it will not have any physical reaction, chemical change with it. No, you can't even see it! Because it doesn't emit light, it doesn't participate in Electromagnetic interactions."

"In the universe, it doesn't even know it exists except to fix the original distorted space-time, that is, the gravitational field."

"If it accelerates absorption, then it accelerates in time. Envelop the entire Earth in a time acceleration field, and you'll see a fast-growing Earth..."

"On the contrary, if a person wants to rejuvenate his youth, it is enough to discharge his own time, and the position and state of matter will be reversed."

"If you want to go back to a bygone era, you can discharge the entire space and the time of all the matter inside."

Hawking understood, so that the grandmother paradox would not be contradictory.

Assuming that A has released all the matter in the universe, for example, it has been released for fifty years, then he has returned to fifty years ago.

He killed his grandmother, but this did not lead to his disappearance, because as early as when he turned back time, he had already 'killed' his mother, and he erased all the things that were born in fifty years, Rewinds all particles to their past state.

A Back to fifty years ago, it belongs to the "island in the long river of time", and it will not return to fifty years later. Time is irreversible, history is history, and the past is the past.

He just let everything, change direction, start all over again.

"Rewinding time does not change history, but creates 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 reversed 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."

Hawking is not surprised, the other party cannot change the world just for him, there must be other reasons, seeing that he is incidental.

This is simply unimaginable technology! How much damage does this do to the universe?

The most terrifying thing is that those who are in it will not know that time has been reversed, and will not find any traces.

"Unbelievable, how many years has the universe regressed? Has mankind ruled the entire universe in the future? How many years has this been developed for a terrifying technology?" Hawking was completely stunned.

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 made him and Elaine completely stunned.

"Professor Hawking, I never said...I am human."
