Chapter 114

Elaine saw Hawking breathing better, and Huang Ji a question and answer, then silently stood aside, dare not interrupt, even dare not breathe.

She doesn't know how to change history or create history.

Elaine only knows that she must be witnessing history.

Hawking pondered for a moment. He did not understand the meaning of Huang Ji's words. History could not be changed, but only created? He didn't want to hear such vague answers.

"Are you really a time traveler?" he asked? I still can't believe it. When I saw that invitation, I felt that the world I had understood in my whole life was collapsing. "

Huang Ji didn't say a word.

"I'm not going to send out an invitation," Hawking said. "I can tell you very firmly that I won't send an invitation!"

"Please don't say that you will send out the invitation letter instead of me. You should understand that I am asking a question equivalent to my grandmother's paradox. Please tell me, why did you come to my party?"

"Professor Hawking, as a scientist, you should understand that paradoxes don't really happen."

"When you think something is a paradox, there must be some misunderstanding here."

Hawking asked, "please tell me, what's the misunderstanding? Since you've come to my party, you'd like to satisfy my curiosity? "

Huang Ji said, "of course, Professor, I will also learn from you."

"OK." Hawking agreed without hesitation.

He didn't care what Huang Ji needed, even if it was life. He had been sentenced to death by the doctor for a long time. It was his curiosity about the universe that drove him to live to this day.

"If a went back to the past and killed her grandmother before her mother was born, people would take it for granted that this would create a contradiction, leading to a not being born and not killing her grandmother through time and space," Huang said

"This is the grandmother's paradox put forward by Heine, which is widespread and classic. It also represents the arrogance of human beings for taking time for granted."

"In the story of the grandmother paradox, it is forcibly assumed that" a is a person whose grandmother has not been killed but was born normally. "At the beginning of logic, a history of" grandmother alive "is implanted into people. This premise is clearly assumed."

"After arranging a" normal history "first, and then assuming a history of killing grandmother through time and space, a B history is created."

"In the later story, history a and history B are put together and compared as" simultaneous "events. It is said that this is contradictory. Isn't that nonsense? "

"Alexander's conquest of Egypt is a kind of history. His failure to conquer Egypt 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 is clearly that one person has participated in two kinds of history successively, but misleads people to think that" it should happen at the same time ", that is, he is changing concepts

"This is a typical logic error, a man-made paradox."

Hawking crooked his neck and said, "this is an experiment of thought. Of course, there are assumptions. This man goes through the past and participates in the history of 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 for changing concepts without making people feel disobeyed is that there is a" time travel "setting in the middle

"People don't know anything about going back to the past, so you instinctively feel that it's reasonable to be involved in both kinds of history."

Seeing that Hawking had not figured it out by himself, Huang Ji said with a smile: "if a phenomenon happens, there must be some truth. When people think that something is a paradox, it must be that something in it has been misunderstood. "

Hawking agrees that this is the cornerstone of science.

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

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

as like as two peas, the second is the famous parallel world theory. When a person crosses the moment, he comes to a new world, killing his own grandmother but the identical grandmother of another.

"So You mean parallel worlds? You're standing in front of me, and there's no paradox, so you're from another parallel universe? Am I wrong... " Hawking said.

He does not support the parallel world. He thinks that time travel does not exist in order to save the paradox from happening.

Now Huang Ji stands in front of him. He can only think that Huang Ji comes from a parallel world.

However, Huang Ji shook his head and said, "no, actually you are right. Your theory is closer to the truth, Professor Hawking. Time travel does not divide parallel worlds. "

Hawking's eyes moved abruptly, greatly surprised.

What? Not parallel world theory? Is timing protection closer to the truth?How is that possible? In other words, time travelers travel through the past of their own world? Isn't it still a matter of facing the grandmother paradox?

Huang Ji explained: "the grandmother paradox, the wrong premise is that time travelers can enter the history of the past Back to the original history. "

"This is people's biggest mistake: time as space."

"People can't perceive time as if they can't perceive a higher dimension, so they can only make analogies and guess what it looks like."

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

"This has led everyone to understand time as a road, time travel as being able to return to the starting point after returning to the past."

"Finally, I compare the contradiction between" the world before I changed "and" the world after change ". Isn't that nonsense? "

Hawking said, "you mean you can't go back to the past?"

"What about the original world?"

Huang Ji said with a smile, "look, you are imagining the original world again."

"The reason why people feel paradoxical is that they force themselves into a world that doesn't exist."

"Time has been misunderstood. It should not be compared with space, but with light."

"Light Reflected back, do you think the light is flowing back? It's just a change of direction. "

Hawking was silent and then asked, "so what is the nature of time?"

"The essence of time, you can imagine it as a substance," Huang Ji said

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

"Time also has the properties of particles, which are absorbed by all things like quantum of light. This absorption itself does not consume time. It is actually the intrinsic property of matter

"It's like quantum fluctuations, which appear instantaneously and are consumed instantaneously."

"All things include space. They absorb time, so they can change themselves. They can only absorb, but not emit. Just like entropy increase, it has only one direction. The "time entropy" consumed will only increase, not decrease. "

"If matter does not reabsorb time, it will stand still. It's a little bit like energy, isn't it? Time is a kind of fuel, but it belongs to 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, energy will also be static, and the world without change will be meaningless."

"The more time that everything absorbs, the faster it changes. Otherwise, the slower the time. This is related to the mass, and the larger the space distortion, the lower the rate of time absorption. And the most efficient is undoubtedly the rate of time absorbed by a zero mass object in vacuum. "

Elaine in the side to listen to clouds and mountains fog cover, small face muddled force.

Hawking was stunned. Huang Ji regarded time as matter and energy, and regarded space as matter. Finally, he unified them together. He proposed the concept of time entropy, which conforms to reality and preserves the second law of thermodynamics.

Relativity and quantum mechanics are two buildings of human physics, but they are not compatible with each other. The biggest contradiction is the understanding of time and space.

People have been looking for a theory to unify them, and then string theory and other things have to be added to the conjecture of high dimensions.

However, Huangji, however, has a new way. It directly regards time as a matter like quantum fluctuations. It is born one by one. It has no mass and no force, so it is not observable.

The only proof of its existence is that the time of a massive object is slow.

Huang Ji compatible relativity with quantum mechanics.

"It's amazing. Can you prove it? Can you deduce it from a mathematical description? " Hawking said eagerly.

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

“#@￥#@#@…… ￥#@！” Hawking's language barrier appeared again, and he couldn't say a word in half a day.

he knows that the problem is not just the first mock exam. His limited life is difficult to see the universal grand unified model.

"So the essence of time travel is not to cross into the past on the time axis, but Emission time? " Hawking slowly calmed down his mood and immediately deduced the method of time reversal according to Huang Ji's theory.

Huang Ji said, "yes, it's a theoretical way to regress time. Just as life is a low entropy body, which can emit the entropy of the body, it actually intensifies the entropy increase of the universe as a whole. "

"The same is true for the discharge time. Generally speaking, it is impossible to discharge emissions, but in theory, technology can be used to realize "time emission". One emission will lead to the other to bear the responsibility. Emission time itself will consume time, and the total time of the universe is limited, so it will eventually lead to "Time silence", the time entropy increases to the limit"Time is Is it limited? "

Huang Ji said: "people's biggest misunderstanding of time lies in this. The total amount of time is limited, which is cruel, but the fact is."

"The total amount of matter in the universe is limited, the energy is limited, and the space is limited. Why is time infinite?"

"When physicists are committed to unifying time, space, energy and matter, they all regard them as" the same thing ". In essence, they are the same thing."

Hawking is silent. If we want to establish a unified theory, then these four things are actually different manifestations of the same thing.

Huang Ji continued: "both absorption and emission are consuming time, but emissions are consuming double. So Dr. Hawking, you are right in your theory that time is irreversible, but the universe can return to its past state, which is not contradictory

"If an object stops absorbing time, then it will be stationary. No matter how you attack it, it will not produce any physical reaction or chemical change with it. No, you can't even see it! Because it does not emit light and does not participate in electromagnetic interaction. "

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

"If it accelerates absorption, then it accelerates time. Envelop the whole earth in the time acceleration field, and you will see the rapid development of the earth... "

"On the contrary, if a person wants to rejuvenate, it would be better to discharge their own time, and the position and state of matter will flow backwards."

"If you want to go back to the old days, you can discharge the whole space and all the time inside."

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

Let's say that a has discharged all the matter in the universe for a period of 50 years, then it is back to 50 years ago.

He killed his grandmother, but that didn't lead to his disappearance, because he had already "killed" his mother when he was back in time. He wiped out all the things that had been born in the past 50 years and made all the particles go back to their former state.

A back to 50 years ago, it belongs to "an island in the long river of time". No more than 50 years later, time is irreversible. History is history, and the past is the past.

He just let everything change direction and start over again.

"Time reversal does not change history, but creates history..." Hawking thought of Huang Ji's first words.

This conjecture is amazing No, it's not a guess. It's a time traveler. He said fact?

"You have irreversibly reversed the whole universe in order to come back to see me?" Hawking panicked.

Huang Ji said with a smile, "it has nothing to do with you."

Hawking is not surprised. The other party can't change the whole world just for him. There must be some other reason to see that he is by the way.

It's just incredible technology! How much harm does this do to the universe?

The most terrible thing is that people in it will not know that time has been retrogressed, and they will not find any trace.

"Unbelievable, how many years has the universe regressed? Will humanity rule the universe in the future? How many years has it taken to develop this technology? " Hawking was completely lost.

However, Huang Ji said, "it has nothing to do with human beings."

Hawking was shocked. It had nothing to do with human beings? What does that mean?

Huang Ji's next words, let him and Elaine completely dull.

"Professor Hawking, I never said I'm human. "
