At that time, all kinds of incredible scientific and technological advances and unforeseen disasters followed, and the revolutionary invention of the billion-fold light-speed spaceship was followed by the collapse of the intelligence of all mankind, as if God intended to make mankind crazy in the rubbing of joy and sorrow.

——Excerpt from "A Hundred Years of Collecting Shellfish", written by Yu Leshui

Chu Tianle's solitary wave theory soon became recognized in the scientific community. The cataclysm passed without danger, and the world began to return to normal from the "wartime economy". The six spaceships were indeed wanted back by their original owners, because the world has already risen a space tourism craze, and most of them are now short trips, to the planets of gold, wood, water, fire, earth, Neptune, and Celestial, or to the Kuiper Belt and the Oort Nebula. However, long-distance travel has been actively prepared, and it is still limited to the Cowherd Star 16 light-years away from the Earth, because at the speed of Mach 1.8, it takes 18 years to make a round trip to the Cowherd Star, which already accounts for a quarter of the tourist's life. If you want to go to a farther planet, you will definitely have to develop a ship with a higher Mach number, but this will require a new theoretical breakthrough. These faster-than-light ships are hot, not to mention six, sixty is not enough. The new spacecraft is being built at a frenzied pace because, according to the theory of isolated waves, the supercritical vacuum that can excite the second-order vacuum will return to the tipping point after twenty-three years, and at that time, humanity will have no choice but to say goodbye to the faster-than-light era, so people are scrambling to get on the last bus.

Now that the catastrophe has passed, the UN Security Council proposes to dissolve the SCAC. However, after discussions at the UN General Assembly, it was decided that the SCAC should remain for the time being, and that it would not be formally disbanded until the aftermath was completely completed. The headquarters of "Friends of Music" shows no sign of disbanding at all, because the "brain", "cerebellum" and "heart" of "Friends of Music" are still working nervously at the same rhythm as in the past. Although the donations to the "Friends of Joy" will certainly have shrunk greatly or even dried up after the catastrophe, with the current financial situation, it will not be a problem to maintain the operation for ten or eight years.

Ji Renrui instructed Lu Junding to continue to strictly protect Chu Tianle. This thing is a bit illogical to say - you know, it was Chu Tianle, the sick pigeon, who tried his best to flap his sick and disabled wings, and brought an olive branch to Noah's Ark, proving that the flood had receded! But the problem is that the forecast of the flood that year was also made by Chu Tianle, although that forecast was not fake news, it was also a false alarm, which inevitably made the people feel inexplicable. It would be an exaggeration to say who would assassinate Chu Tianle because of this feeling, but with the lesson of the last time, there is no harm in being cautious.

Chu Tianle is very worry-free, since the death of his mother, he has been staying at home in the mountains. He always drove his wheelchair out of the hospital alone and stayed motionless for hours. His gaze was staring into the distance, staring at the blue sky and white clouds, staring at the deep sky behind the blue sky. Cao'er has learned not to disturb her father at this time, as long as her father "turns into a stone statue", she will go to Aunt Xu or Uncle Lu to play. After Yu Le Shui finished the official duties of the foundation, she went home to spend as much time as possible with her husband. She could feel that within her husband's stone-like shell was a rapidly spinning mind machine, already spinning on the verge of speed. Yu Leshui thought that her husband must be fulfilling his promise to his mother, and was trying his best to find a way to rescue Liu Ye Yangyang. She also noticed that her husband often had a piece of paper on his lap with Pauli's formula printed on it, the formula that Pauli often boasted of as "having the beauty of simplicity and symmetry", and it seemed that her husband could not let go of his thoughts of Pauli either. This eccentric with albinism is probably the person with whom her husband knows best in the academic field.

It was long before she learned that in addition to the sense of responsibility and guilt that drove her husband's thinking machine into high speed, there was also a more powerful motivator - fear.

In her spare time, she also considered preparing gifts for Changchang, and Miao Qi said that he was going to get married soon, and he organized a group wedding with the people of Ji's fleet, which was said to be held in space.

The "little bee" flew above the "bubble" company, and today it was Kang Ping, the well-dressed general manager of the company, who personally drove it. He pointed triumphantly to the following:

"The following are the company's two main plants, please visit the brothers."

There were also seven people on board, six captains of the Ji fleet plus Emma. The "Little Bee" they flew on was a "military-to-civilian" product and a sightseeing vehicle modified from the "Little Bee" for space. Its hull, including the bilge, is basically completely transparent, and the fusion device, which has been extremely miniaturized, is placed on the upper part of the engine room, which does not affect the line of sight, so it can be easily overlooked. Today, under the cabin are two production halls arranged in a T-shape. A workshop is transparent, lying horizontally on the ground, made of transparent hollow balls with two ends cut off and connected, resembling a giant multi-segmented green worm. Its head is next to the road, and hundreds of large dump trucks line up in front of the workshop gate, loaded with garbage or industrial waste. After swallowing the garbage, the giant green worm is crushed and squeezed into shape in its body, and finally spits out variegated hollow balls from its tail. The balls look small from the sky, but they are life-size to a four-bedroom house – and they were designed for that. The other workshop is upright, but it's actually a spaceship, headfirst down on the ground, with longitudinal lines lined with magnetic coils for particle accelerators. Unlike spaceships, this "factory spacecraft" has a transparent shell added to the particle-accelerated orbit, and a vacuum is pumped into the sandwich.

The hollow ball spit out by the big green worm directly enters the spaceship-type workshop through the conveyor belt, and is excited inside to realize the reconstruction at the atomic level, so that the hollow ball made of garbage instantly becomes a beautiful transparent hollow ball, and then rolls out from the other end of the workshop. This end is also connected to the road, and the large dump truck that had previously delivered the garbage has been washed and returned here. The hollow ball rolls directly into the compartment, the carriage automatically stands up, and the vehicle drives away. The process is streamlined, with one piece being completed every half minute.

Ji Jichang asked: "With such an efficient production line, why don't you build a special railway?" ”

"It's too late for this factory, and the next ten factories will have to build special lines. Brother Changchang, I have to hurry, you big-headed scientists have said that after twenty-three years, the vacuum will not be able to be excited, and my factories will be useless. I need to hurry up and digest as much garbage as I can from the world. This is my grandfather's last order to me, and his old man is there," he said, pointing to the heavens, "and staring at me every day." ”

Ji Jichang said: "What Brother Changchang, it's Brother Chang!" We've just verified. ”

The two of them are bare-ass friends, Kang Ping is big, and he has always been a brother, but not long ago, after verification, Ji Jichang was three days older than Kang Ping. Kangping said with a hippie smile:

"It's only three days, it's a negligible error, and the old name is used to it, so it's changed. Besides, you're here to beg my brother today, shouldn't your mouth be sweeter? ”

"Please don't have a sweet mouth, our rules, the one who borrows money is the uncle."

Emma smiled and said, "Brother Niu Niu, ignore him. I call you brother, and we all call you brother. ”

Capdevilla, Tian Mi, Ogfner, and Kasseline said in unison: "Yes, we all call brother." Only Ma Ming has a relatively old personality and is older than Kang Ping, he didn't shout, but he just smiled and didn't deny it.

"That's right. Let's go to my office area. ”

Not far from it is the office area, each building has a different shape, but all of them are spherical as the basic unit. The main building is a 30-storey building, which is spoked from the cross-sectional view, with 12 spheres connected into a large circle on the outer circle, which are stacked layer by layer to form a column 90 meters high. In the center of the cylinder is a column formed by a single sphere connected up and down, and an elevator and a walking ladder are installed inside. The cylindrical shape is connected to the outer ring by six spokes, which are still spheres. All units are transparent and have an unobstructed view of the interior, with a floor at a third height of the ball, on which is the space for personnel to move, and under which various facilities and pipelines are placed. Employees are working at their desks.

The "little bees" landed on the roof of the building, and Kang Ping led them to the general manager's office on the 30th floor through the elevator. The professional female secretary smiled sweetly, poured tea or coffee for everyone, turned the walls to opaque green, and then withdrew, gently closing the door. Kangping Says:

"Brother Chang, you said to find a confidential place to talk, this is it. If you have something to say, your business is my Niu Niu's business. ”

He once again emphasized the title of brother and brother, apparently trying to "take advantage of the danger of others" to create a fait accompli. Ji Jichang smiled and didn't bother with him anymore. Emma spoke first:

"Brother Niu Niu, we need a lot of money."

"Didn't say that. Although my company nominally belongs to my grandfather, Uncle Chu and Uncle Ge, the three of them have already let me go, and all this money belongs to 'Friends of Le'. ”

"No, I want to hide this matter from the 'Friends of Joy' for the time being."

Kang Ping hesitated for a moment, "Then this matter is a little more troublesome, but—you go on first." ”

"We want to hold a group wedding in the sky, and the brothers of the Ji fleet are going, so we need to rent six wormhole-type spaceships."

Kang Ping smiled, "I thought it was a big deal, I could solve the rent of six spaceships with my private money......" He suddenly paused, and looked at Ji Jichang with sharp eyes, "You guys...... Still want to do that baby universe? ”

Ji Jichang smiled, "I said earlier, I can't hide it from you old profiteer." yes, we can't let go of that. ”

Kang Ping shook his head, "The catastrophe is easy to pass, the old universe is safe and sound, human beings have caught up with the hydrogen era again, and the small days are so rich that it is simply a paradise flowing with milk and honey, which I didn't dare to dream of thirty years ago." In the face of such a paradise, you still can't die that heart? That's not much like suicide. ”

"Yes, we can't die that heart. This opportunity to explore the new world is fleeting, and we will not be blind if we don't seize it. ”

"Ji Fleet of 6,000 people are going?"

"We haven't connected it yet, we'll wait until we get our hands on it. But I estimate that at least half of them will follow. ”

"I heard that Uncle Ji, Uncle Chu, and Aunt Yu have all expressed that they want you to give up this unnecessary adventure?"

"Yes, they did say no." Ji Jichang said frankly.

Kang Ping's sharp eyes stared at the seven people in turn, and the seven of them looked at him quietly with calm faces. Kangping turned to look out through the wall, and under his gaze, the wall automatically returned to transparency, revealing a clean blue sky with faint white clouds moving slowly. After a long time, Kang Ping turned his head, shook his head, and said:

"Brother is a layman, a businessman, and a marketman, and he really can't understand your madness. Leave this matter on me, and I won't go to kill it. If I help you, it's almost the same as helping you commit suicide, and maybe even get into a lawsuit. Tian Mi and Emma wanted to talk, but Ji Jichang stopped them with his eyes. But just now I suddenly remembered my grandfather. It was a strange old man who only liked to play with children and make friends with young people all his life. I'll let you tell you a secret, he is actually very withdrawn among his peers, and he hardly interacts with everyone, because he has never been interested in general 'adult topics', such as stock speculation, class treatment, parental shortcomings, etc. It can be said that he was always a big child, and some strange ideas always popped up in his mind, one after another, until he was over eighty years old, and he could not stay at home to enjoy happiness, and finally threw his old life on the moon. "Everyone looked at the sky with his gaze, and now they can't see the moon, but they seem to see the three martyrs behind the moon." As I said, as a merchant, I will definitely refuse your request and will never go to the thief ship. But it occurred to me just now, if my grandfather was here at this moment, what would he say? I think he'll agree. Of course, I'm not saying that Uncle Ji and their decision was wrong, no, that must be right, but my grandfather is not bad either. Both opposing opinions are true. He smiled and said, "Anyway, no matter who is right or wrong, Brother Niu Niu has decided to help you." ”

Ji Jichang praised the festival: "Good! Just as I expected! He smiled and added, "You will be my brother in the future, and I will never fight again." ”

"Now you know that your mouth is sweet? Okay, brother will help you fulfill this wish. It's just that after you're gone, how am I going to see your parents? ”

"We will leave a farewell letter before we leave, and we will not embarrass you if we say it thoroughly."

"Let's not talk about this for now, since the big policy has been decided, the side issues will be put later. Now let's start with transactional scheduling. To be honest, because of the accelerated expansion of production capacity, I am very short of funds, and I can't afford to buy six spaceships for a while......"

"We've taken that into account, so there's no need to buy six ships, just a month's rent for six ships."

Kang Ping looked at him suspiciously, "And ...... You guys just play missing? Let the creditor scold your ancestors for eight lifetimes? ”

Ji Jichang said indifferently: "My dad said that doing big things is not informal-it seems that your grandfather also said this." The point is that we are doing the right thing, we are going on an expedition as a representative of humanity, so although our behavior is a bit tricky, we have the confidence in our hearts and are not afraid of being scolded by others. Besides," he said with a smile, "the creditor must be more lenient with the dead—you know, whether or not we survive in the new universe, we are already dead in this universe anyway." ”

There was pathos in the bones of these words, which made Kangping look at them for a long time. In the end, Kang Ping came back to his senses and shook his head with a smile, "No, this kind of practice is too scoundrel, and it will ruin Uncle Ji's reputation, as well as the reputation of 'Friends of Music'." Listen to my brother, I'm going to do this: lease six spaceships in the name of my company, and then secretly load them with enough supplies for you for three years. This has the advantage of using a spaceship to transport supplies in the name of a factory, which is not easy to arouse suspicion. Then I made a big splash in the media in the name of holding a public welfare event, saying that I would hold a space group wedding for thousands of people for free. When you succeed in disappearing, I will quickly carry the debt. Although I can't come up with that much money at the moment, as long as ten new factories are put into operation, there is a lot of money. Moreover, I am not spending this money for public and private purposes, and I think you are still doing the business of 'Friends of Joy'. ”

"Yes, it's definitely still the cause of 'Friends of Music'. Brother Niu Niu, thank you for your kindness. If we can gain a foothold in another universe, we will repay you well. Emma said with a smile.

"How do you repay?"

"Advertise your products for free in New Universe. Otherwise, I'll just give you a planet. ”

"This favor is a little too far away, I understand the kindness; As for the advertising effect, I don't count on it. When are you ready to go? ”

"Mid-Autumn Festival, that is, a month later."

"Time is tight. Now, make a list of supplies, and I'll prepare them for you. ”

Ji Jichang looked at Tian Mi, she immediately took out a thick list and handed it over with a smile. Kang Ping said mockingly: "The list has been prepared a long time ago? Looks like you're going to eat me. He took the list and read it roughly, "No problem, I can't do it except for the light weapons you want - China does not allow arms deals, and I don't want the company to suffer lawsuits - I will leave the rest to me." ”

"It's okay, let Emma go to the United States to buy weapons."

Kang Ping suddenly thought of a question, "Oh yes, I know that the thousand and six crew members of the Ji fleet have been pre-matched to 3,000 couples, but they haven't had time to hold a wedding yet." What if the people who sign up to go are not husband and wife, or if there are more men and fewer women? ”

Ji Jichang said nonchalantly: "Then re-pair." If there is a disparity between men and women, it is polygamy or polyandry. Don't forget, that's what the Noah is. ”

Kang Ping shook his head, "I would never let me do this." However, you are people of the new universe, and you must be new ideas, so I will not take a moral class. ”

Even if this important event was negotiated, it went smoothly as expected. The seven representatives were all excited and surrounded Niu Niu in the middle. The four women held Kang Ping and said endless sweet words. Emma proposes:

"Brother Niu Niu, let's talk about such an important matter, shouldn't we celebrate tonight?"

"Needless to say, I'm the host again, right? Who made me a brother! Okay, I'll let the secretary arrange a meal every night from today. We see each other and see each other less, Changchang, although I know that you are going to do business, but I really can't bear to say goodbye. ”

After a month is intense secret preparation. Each captain spoke to a thousand of his men on the phone, and the first thing in the call was that the other party must promise to keep it strictly confidential, whether they agreed to what was going to be said or not. After receiving the promise, the various captains communicated the secret plan. The departure time is set for the Mid-Autumn Festival, and those who are willing to go must register fifteen days before the Mid-Autumn Festival.

Calls came one after another, and by the deadline, there were exactly over 4,500 applicants. The "male-female pairing problem" that Kang Ping once worried about basically did not appear, because most of the applicants went together after consultation with husband and wife. There were also a small number of solo flights, and Ji Jichang asked Tian Mi to be responsible for re-deploying. Although this was a large-scale covert operation, it was not very difficult to carry out because it had been trained for many years, especially after a real combat exercise. So everyone knows exactly what to do, and perhaps the most important thing is that they are mentally prepared and have the courage to see death as home. This year's Mid-Autumn Festival is three days after the National Day, before the National Day, Ji Jichang gave his companions a holiday, let everyone go home to accompany their relatives, this is the final reunion. Of course, everyone was sternly warned in advance: when they returned home, they would inevitably face the invasion of family warmth, and if they changed their minds, they would not have to come back, but they must not reveal their secrets.

Ji Jichang also went home. Changchang's mother has been busy preparing for the wedding for a long time, but she can't get an idea. Changchang and Emma had said that they would go to space, in the old place they had been to last time, for the most chic group wedding, and most of the old companions of the Ji fleet would attend. Such a chic tourist marriage is of course good, but the new house also has to be prepared, but the two babies don't care about the new house, and it is not too late to worry about the new house after the wedding. The strange thing is that Ji Renrui didn't care about the new house, so Miao Qi had to be busy alone.

The day before the National Day, my son came back, but Emma did not come with her, saying that she had gone back to the United States to visit relatives and would be back tomorrow. Miao Ji complained: "Seeing the wedding date, the parents over there promised to come, what kind of relatives are they going to visit at this time!" The son didn't explain, just giggled. She had no choice but to take her son to see the new house and ask him what should be improved, and Changchang was full of praise and said that everything was fine. Then I asked my parents to take advantage of the "Eleventh" holiday to travel, and have fun for a few days, and it was best to bring Uncle Chu's family to go with him. Ji Renrui said flatly:

"Don't go anywhere, just spend the holidays at home. Maybe your Uncle Chu has something to look for you. ”

On the morning of "Eleventh", Emma had just arrived home, and Chu Tianle really called Changchang and asked him to go on vacation in the mountains. "By the way, I'll talk to you about one thing. Changchang, call the other captains of the Ji fleet together, and Emma will come too. ”

Ji Jichang and Emma looked at each other, and there was a little drum in their hearts, Uncle Chu asked all six captains to go to him at this moment—when the secret operation was about to begin—could it be that he was aware? Anyway, since Uncle Chu invited, they would definitely go, and it was not impossible to take this opportunity to talk thoroughly. With Uncle Chu's heart, he should support them.

He immediately rushed with seven companions, and one more was Xi Mingzhe, who was not very old, but steady and capable, and quick thinking, and was the captain he had recently looked at. Sister-in-law Xu prepared a lot of snacks for the guests, and took out the mooncakes prepared for the Mid-Autumn Festival in advance. Cao'er rarely saw so many guests, and she was crazy and pulled Brother Changchang and Sister Emma and didn't let go. Someone suggested visiting the crematorium and other attractions, which are the places mentioned in Aunt Yu's famous interview twenty-nine years ago. Yu Leshui said, "Okay, I'll take you there." Chu Tianle suddenly said:

"I'll take them there. It's been a long time since I've been there, and I'm just thinking about going there. Hey, Changchang, do you have the strength to carry me on your back? ”

Ji Jichang smiled and said, "No problem, we eight young people can't deal with you?" With that, he pulled him out of his wheelchair and carried him on his back. After carrying it on his back, he was a little sad, Uncle Tianle was as light as a swallow, no wonder Aunt Yu once joked, saying that carrying him was like Sun Dasheng carrying a red child. Chu Tianle said to his wife:

"You don't have to go up, you can play with the grass at home."

The grass doesn't follow, and the noise has to go. Yu Leshui squatted down and whispered to her, "You can go." But Dad wants to talk to these uncles about serious things, and you are not allowed to make trouble, you are not allowed to go crazy, okay? ”

Cao'er asked sensibly in a low voice, "Is Dad going to be a stone statue again?" I know, I don't make trouble. ”

So, Yu Leshui and the grass also followed. A group of people came to the crematorium first, and the ground was charcoal chips left over from two burnings, and on top of it was a new pile of pine wood, which had not yet dried, which was prepared for the next deceased (it should be Chu Tianle). The scene in front of her inevitably aroused people's sadness, and Cao'er also thought of her grandmother, with tears in her eyes. Everyone hung silently for a while, Ji Jichang settled Chu Tianle on a stone, and eight young people sat around him on the ground. This disabled person has always been a god in their hearts, and Chu Tianle must have a deep meaning when he summoned them this time. They quieted down, their eyes staring at Chu Tianle, and of course they were inevitably a little "ghostly". Chu Tianle said:

"Come, let's talk. You're all at the heart of the Hime-Ship fleet, and I know that after that operation was canceled, your hearts haven't been scattered and you don't want to give up on the exploration of the baby universe, right? ”

Ji Jichang looked at Uncle Chu and looked at his partner, although Uncle Chu didn't say it thoroughly, it is estimated that he already knows something about secret operations. Ji Jichang said briefly: "Yes." ”

Tian Mi hurriedly changed the topic: "Uncle Chu, we are not willing to let the faster-than-light era end in twenty-three years. Can you show the way? ”

"I've been looking for it, and it's been very hard."

"Did you find it?"

"I seem to see an island at the end of the sky, but I don't know if it's a mirage. I have invited you here today just to ask you to help me confirm or deny it. ”

The eyes of the eight people suddenly lit up! Uncle Chu has never said lightly, he should be seventy or eighty percent sure when he says this. If...... That's exhilarating! They all forgot about the "ghost fetus" in their hearts for the time being, and pricked up their ears. Yu Leshui, who was standing outside the circle, also listened carefully, knowing that her husband's thinking for half a year was about to bear fruit.

"Let's take a step further and say two well-known trivia. We all know that chemical reactions are often inseparable from catalysts, such as platinum, rhodium, copper, manganese dioxide, etc., which can promote the reaction speed, but do not participate in the reaction, and still retreat after the reaction. ”

This is indeed the most basic common sense, and middle school students know it. But everyone knew that Chu must have a deep meaning in telling these common senses, and they all listened carefully.

"Also, there are ghost variables in mathematics. Some integrals can't be performed, and you need to set a ghost variable as the intermediate value, and the good thing is that after the integration is over, the ghost variable can be completely eliminated. So, it can also be seen as a catalyst in mathematical operations. ”

Everyone nodded.

Chu Tianle began the topic, "You may remember how the three-state vacuum theory came about. More than 20 years ago, a 10-year-old boy named Yang Yang said that if there was energy in the vacuum, flying in space would be like sailing on a sea of energy. Because a conventional spacecraft spends most of its energy on accelerating the fuel itself, if energy is readily available from space, even in very small amounts, such as the light pressure of a star, it can eventually bring the spacecraft infinitely closer to the speed of light. ”

The faces of Yang Yang and willow leaves appeared in front of Yu Leshui, and they were sailing into the far space in high spirits, not knowing that there was a quagmire waiting in front of them. Cao'er whispered, "Mom, I know Uncle Yangyang and Aunt Liuye!" Yu Leshui put her finger to her lips and asked her to listen to her father quietly.

"It was inspired by this ten-year-old boy that I made the discovery that a supercritical vacuum can be annihilated by high-energy excitation and converted into low-intensity light pulses that release slightly more energy than they excite and can be used to drive spacecraft. It can be said that 'vacuum annihilation is a release reaction' is the basis of all applications. ”

Ji Jichang said: "Yes. It was only later that there was an unexpected change, and the spaceship was changed from light pressure drive to 'wormhole drag'. ”

"Yes, you're right. However, due to the inertia of thinking, people have not been able to realize the key mechanism contained in this for a long time, that is: the condition that 'vacuum annihilation belongs to the release reaction' is actually just a catalyst and ghost variable in the discovery process of the faster-than-light spacecraft, and it can be completely retreated! To put it another way, whether or not you can achieve faster-than-light flight depends only on whether you can annihilate the vacuum, and it doesn't matter whether it is a positive reaction to release energy or a negative reaction to absorb energy! He paused for a moment and said calmly, "Changchang, think about it, what inspiration can you get from it?" ”

He stopped talking, beckoned Cao'er to come over, and took Cao'er into his arms, and the father and daughter whispered gossip. Here, the eight people were silent and thinking feverishly. Chu Tianle gave them a problem, behind the problem may be a Strait of Magellan leading to the new world, and they have to fully use their brains to use the wisdom given by God to mankind to discover it. After more than ten minutes, Ji Jichang spoke first:

"Uncle Chu, you are saying that the original spacecraft design was based on a supercritical dense vacuum, which can be annihilated by high-energy excitation, and release low-intensity light energy, and the release energy is greater than the excitation energy."

"Yes."

It is this that shackles our thinking, if we don't care whether it is releasing energy or absorbing energy, and then think about it, can the vacuum below the critical value be excited? Because we can dramatically increase the intensity of excitation, even if it requires a huge amount of energy! We already have fusion technology, and faster-than-light ships can easily get fuel while sailing. Because hydrogen is the most abundant element in the universe, liquid hydrogen planets abound. Moreover, wormhole flight can be parked at any time, without having to spend a lot of fuel and time for parking once. ”

"Yes!"

"And it's not just a dense vacuum below the critical value, maybe even a standard vacuum, or even a sparse vacuum, can be excited? Of course, the excitation energy must be much higher, at least above 8TeV, otherwise Fermilab and CERN would have been annihilated by vacuum excitation in a standard vacuum since the last century. He added, "But it also shows that Zelidovich's worries back then were not unfounded." ”

Chu Tianle didn't answer again, but the light on his face already said everything. He looked up at his wife. His wife read the silent words in his eyes—I had found the way to catch up with Noah, and my mother could rest in peace above the Nine Heavens. Ji Jichang exchanged fire-like glances with his partners, unable to hold back the ecstasy in his heart. Mankind once opened the door to faster-than-light flight, and then sadly learned that this gate was about to close, and the first bad news it brought was the tragedy of "Noah". But Uncle Chu's new vision has the potential to reopen this door, and once it is opened this time, it will never be closed again! Human beings no longer have to worry about the imminent end of the era of dense vacuum, because the standard vacuum or even the sparse vacuum is not the weak water described in "Journey to the West", and it is still possible to sail! The crematorium was filled with a deep joy, and they did not know it at the moment, and even greater joy awaited them. Chu Tianle asked:

"So imagine how fast the ship would be if the standard vacuum could be excited?"

Ji Jichang misunderstood the meaning of his words, and said: "I think it should be able to catch up with the speed of the ship in the dense vacuum, there is no essential difference between the two in principle, as long as there is sufficient energy...... he was suddenly stunned, because he realized Uncle Chu's true intention in an instant. A huge gate of heaven suddenly opened, and the bright light that burst out dazzled his eyes, and the extreme joy almost caused him to go into cardiac arrest...... He looked at Uncle Chu's eyes, that's right, Uncle Chu's thoughts must be like this. But the joy came too suddenly, and he didn't dare to move forward. He looked at his companions, they were all extremely smart guys, and they also saw the gate of heaven at this moment, but they were also dazzled, and they didn't dare to speak lightly for a while. Ji Jichang thought carefully for a while before he slowly spoke:

"According to the three-state vacuum theory, the flight by excitation vacuum bubble, or displacement flight, the spacecraft is stationary relative to the local space, so there is no relativistic effect, there is no infinite increase in mass and infinite shortening of length, and there is no magic spell of the speed of light limit, so there is no theoretical limit but only a technical limit to the speed of the ship."

Chu Tianle nodded lightly, "Yes." ”

"The bottleneck of the technical limitation was how high the excitation frequency could be, and it was mainly limited by two factors: how long it would take for a vacuum to return to a standard vacuum after an excitation due to a rush towards the 'navel of the ocean', and how long it would take for the standard vacuum to return to a dense vacuum under ambient pressure."

"Yes."

"The first recovery time is very short, and according to your theory of 'vacuum minimum element steady-state growth', it only takes Planck time to restore a vacant vacuum to a standard vacuum, which can be omitted in engineering. The second recovery time is longer, about microseconds, so the spacecraft's excitation frequency mainly depends on it, and now the ship's speed can only reach Mach 1.8, which is limited by it. ”

"Yes. What's next? ”

"If we increase the excitation intensity so that the standard vacuum or even the sparse vacuum can be excited, then we will cross this bottleneck in one fell swoop, and if we want to increase the speed, we don't need to consider the time of space recovery, we just need to increase the particle collision frequency of the accelerator!" Ji Jichang said.

"So what is the maximum speed of the ship?" Chu Tianle asked, "You might as well make two preliminary estimates: first, the vacuum void excited can reach the level of two thousand meters, that is, each excitation can make the spacecraft move forward by one thousand meters; Second, suppose the frequency of particle collisions could be increased to 30 trillion times per second. The above two values can be achieved through hard work. ”

Emma cried out, "Impossible! That's 100 million times the speed of light! ”

Ji Jichang immediately said: "Don't be busy asserting that it is impossible. Near-light speed ships, which were once impossible, have since come to fruition; One point eight times the speed of light, which was once more impossible, has also been realized. So, as long as you break through the limits of relativity, nothing is impossible. ”

The crowd exchanged joyful glances, and passion pounded in their chests. 100 million times the speed of light! Even the most "bold" science fiction writers would not dare to make such an assumption. Chu Tianle said calmly:

"I can't say for sure that it will come to fruition, but theoretically there is no limit. Changchang, I, your Aunt Leshui, and your father all know that you still can't let go of the baby universe and are organizing a secret operation, right? ”

Ji Jichang looked at his partner, a little embarrassed, and then nodded briskly in acknowledgement.
