City in the sky, Zhou's manor.

A 'Dragonfly' aircraft, escorted by a large group of space fighters, landed steadily in the courtyard of Zhou's manor.

With a "bang", the crowd that had been waiting at the door for a long time rushed forward.

Zhou Wenhai, Ye Huilan, Zhou Wenhua, Tang Yi,...... , and others, all of them showed excitement, and their eyes were firmly fixed on the inside of the 'Dragonfly' aircraft.

With a "click", the hatch opened, and Zhou Xing took the lead in getting out, and then stretched out his hand to hold Tang Xin.

"Daddy, Mommy! We're back. Zhou Xing looked at Zhou Wenhai and Ye Huilan, and greeted with a smile.

In the next second, Zhou Xing looked at Tang Yi and his wife, and greeted with a smile: "Mom, Dad, you're here too!"

"Stinky boy, you're finally willing to come back! You miss me!" Ye Huilan stepped forward and grabbed Zhou Xing's arm, and the corners of her eyes couldn't help but overflow with tears of excitement.

"It's good to come back!It's good to come back!" Zhou Wenhai nodded happily again and again, secretly turning his face away, he didn't want to cry in front of Zhou Xing.

"Xiao Xin!" Tang's mother hugged Tang Xin all of a sudden, crying loudly.

Tang Yi looked at Tang Xin, his eyes were red, he raised his head slightly, and reached out to wipe away the tears overflowing from the corners of his eyes.

I thought they were already dead people, but after 31 years of parting, after the reunion, their tears of joy seemed to collapse, and they couldn't hold back anymore.

"Mom, my brother and sister-in-law have all come back safely! Today is a happy day, let's stop crying!" a young woman walked up to Ye Huilan and said comfortingly.

"Okay, okay! Don't cry! Don't cry!" Ye Huilan wiped away her tears and nodded happily.

"Mom, is she Sister Tang Xin!" a ten-year-old girl asked Tang's mother.

"Yes" Tang's mother nodded embarrassedly, pulled the little girl to her, and introduced to Tang Xin: "Xiaoxin, this is your sixth sister, Tang Ying." ”

After speaking, Tang Ma turned her head to look at the three men and one woman behind her and said, "Come here, this is your brother-in-law, sister." ”

Tang Ma blushed and said to Zhou Xing, Tang Xin introduced the children beside her, and said: "Xiao Xing, this is the second Tang Yi, this is the third Tang Feng, this is the fourth Tang Feng, and the fifth Tang Jun." ”

"Brother-in-law, sister, hello!" the children looked at Zhou Xing, and Tang Xin greeted in unison.

"Hello! Hello!" Zhou Xing looked at the children and nodded with a smile.

"Ahem!" Zhou Wenhai coughed embarrassedly twice, turned his head to the young man behind him, and ordered: "Zhou Yong, you also come over to meet your brother and your sister-in-law." ”

Hearing this, Zhou Yong walked in front of Zhou Xing and Tang Xin, greeted him a little shyly, and said, "Brother, sister-in-law, hello." ”

"Hello!" Zhou Xing looked at the young man who was somewhat similar to him, and nodded with a smile.

"Xiaoxing, she is your sister Zhou Qi, I thought it was ....... Ye Huilan introduced Zhou Qi beside her, and when she thought of parting with Zhou Xing for thirty-one years, her tears couldn't help but fall again.

"Brother, sister-in-law, I'm very happy to meet you, it's great that you can come back!" Zhou Qi comforted Ye Huilan, looked at Zhou Xing, and Tang Xin greeted.

"Yes, brother-in-law, my ears are almost calloused when I hear your name! I finally see a real person now!" Tang Feng looked at Zhou Xing with bright eyes and said excitedly.

"Can my brother-in-law take a photo with me......?"

"I want it too, I want it too!" Tang Ying raised her ears and shouted excitedly, if she could get a photo with Zhou Xing, her friends would not be envious.

It's only been 31 years, looking at a group of younger brothers and sisters younger than Xiaoyu, sister-in-law, brother-in-law, Zhou Xing sighed with emotion, and when Xiaoyu came back, he had a headache.

Zhou Xing nodded and smiled, and beckoned to the crowd: "Of course it's no problem, you all come here!"

"Yes, thank you, brother-in-law!" the crowd rushed towards Zhou Xing excitedly.

Soon, Zhou Xingyi met the requirements of the children one by one and took a lot of photos with them.

"Okay! It's almost time to shoot, let's go back to the house first!" Zhou Wenhai beckoned to everyone.

Everyone nodded in unison and followed Zhou Wenhai towards the house.

There is a large family, but fortunately, the living room is spacious enough to accommodate them.

"Brother, sister-in-law, haven't you been able to find Xiaoyu?" As soon as everyone finished sitting down, Zhou Dan couldn't wait to ask Zhou Xingdao.

It's really a pot that can't be opened, as soon as Zhou Dan's voice fell, the smiles on the faces of Zhou Wenhai and his wife, Tang Yi and his wife disappeared immediately, and the atmosphere at the scene suddenly cooled down.

"Xiao Dan!" Zhou Wenhua's face darkened, glared at Zhou Dan angrily, and scolded loudly.

"Uncle, it's okay! Although I couldn't find Xiaoyu this time, I believe that there will be news of him soon. Zhou Xing smiled and relieved Zhou Dan.

"Really, Xiaoxing, what happened, what caused you to lose contact one after another?" Zhou Wenhai was shocked and couldn't wait to ask.

"It's the 'Cosmic Tree' phenomenon, the space-time wormhole allows us to shuttle to another unknown universe, and Xiaoyu should have encountered a similar situation. Zhou Xing replied.

"Unknown universe! So that's it!" Zhou Wenhai suddenly realized, and also understood why Zhou Xing only came back now.

"Brother-in-law, what is the 'Tree of the Universe'?" Zhou Ying looked at Zhou Xing with a blank expression and asked puzzledly.

"The 'Tree of the Universe' is like the fruit on the tree, linked by branches one by one, Xiao Ying must study carefully, and you will understand it when you grow up!" Zhou Xingchong Tang Ying smiled slightly and introduced vividly.

"Well, when I grow up, I want to be like my brother-in-law and become an outstanding scientist!" Tang Ying looked at Zhou Xing and said seriously.

Hearing this, Zhou Xing smiled bitterly, without the assistance of the great scientist assistance system, it is not so simple to become a scientist.

"Are there many universes?, then how can you find Xiao Yu?" Zhou Wenhai asked worriedly.

"Dad, don't worry! Xing used a special method, we will definitely be able to find Xiaoyu, and we can come back this time thanks to this method!" Tang Xin confidently reassured Zhou Wenhai.

"Okay!good!" Zhou Wenhai nodded happily.

"Xiao Xing, what's going on with that giant spaceship? is that the reason why you let us build a shipyard?" Zhou Wenhua looked at Zhou Xing and asked excitedly.

"Yes, uncle, we have encountered many alien civilizations on this voyage, and their technology far surpasses ours, and next, the development focus of Xingyao Group is to improve the ship-building process and reach the level of manufacturing the Titan as soon as possible. Zhou Xing nodded and introduced.

"Okay, okay! Liu Changchuan should repent of their green intestines this time!haha!" Zhou Wenhua nodded excitedly and laughed.

"Okay, don't talk about business, today is a big day for Xiaoxing and them to go home! The meal is ready, let's celebrate!" Ye Huilan walked from the direction of the restaurant and greeted everyone warmly.

Zhou Wenhai's spirit was shocked, and he hurriedly greeted Tang Yi and said, "Let's go, let's go, Old Tang, we have to have a good drink today!"

"Haha! No problem! No drunk, no home!" Tang Yi laughed and responded happily.

That night, Zhou's Manor fell into a sea of celebration, in contrast, for the entire human society, for countless people, tonight is a sleepless night.

Genius scientist - Zhou Xing, who has disappeared for 31 years and returned to the earth today, the collapse of the global stock market has kept countless people awake at night, and a press conference that will subvert human society will be held tomorrow, which makes countless people look forward to it.

The remnant sun is like blood, the night covers the earth, the stars move, and the night passes in a blink of an eye.

In anticipation, the press conference of Xingyao Group was held as scheduled.

Due to the rush of time, the layout of the huge venue was very simple, but nearly 10,000 reporters arrived at the venue early, and they were not the slightest dissatisfied, one by one, like rabbits, with red eyes, anxiously waiting for the press conference to begin.

Time passed bit by bit, and nearly 10,000 pairs of eyes stared at the booth.

The huge square booth, spotlessly clean, is waiting for Zhou Xing's debut.

With a "clang", suddenly a small door on the inside of the booth opened, and Zhou Xing slowly walked out of the door.

"Bang bang ....... The thunderous applause roared like a huge wave, and after 31 years, Zhou Xing stood on this stage again, which made countless reporters extremely nostalgic.

It's back, and that blood-pumping era is back!

The reporters looked at Zhou Xing on the stage with tears in their eyes and applauded desperately.

"Thank you, it seems that you miss me very much!" Zhou Xing smiled slightly and greeted everyone jokingly.

"Yes!"

The reporters responded in unison, and a huge wave of sound almost lifted the roof of the venue.

"Thank you! It's not easy to stand here today, in order to repay everyone's enthusiasm, I will definitely give you a satisfactory explanation today!" Zhou Xing smiled slightly, looking at everyone and announced.

"Bang bang ....... The applause from the audience became more intense.

"After 31 years, everyone must be very curious about our itinerary, so please be quiet and let me tell you about this long interstellar journey. Zhou Xing looked at the audience and reminded everyone with a smile.

Hearing this, the reporters stopped applauding one after another, and looked at Zhou Xing on the stage with blazing eyes, holding their breath.

"Wuheng is the scientific research mothership we took on this interstellar voyage. Zhou Xing stretched out his hand to compare, and the holographic large screen showed the influence of Wuheng.

After a pause, Zhou Xing looked at the audience and explained: "The decision to enable this interstellar journey is mainly to achieve two purposes, one is to explore the unknown universe, human civilization has just opened the age of interstellar exploration, our understanding of the universe is very limited, how big is the universe? We have no way of knowing; second, I was looking for the Rock, because I have always suspected that the Rock is missing, and there is a very special situation; sure enough, after this expedition, I found the reason for the loss of the Rock, and also learned some of the mysteries of the universe. ”

Hearing this, the reporters in the audience were all shocked, their eyes were shining, and they concentrated their spirits, waiting for Zhou Xing to solve their doubts.

Looking at the audience's reactions, Zhou Xing smiled with satisfaction and explained: "There is a very interesting view called the cosmic bubble theory, which holds that the universe we live in is actually a bubble, and each universe is like a soap bubble in the huge multiverse space, born from its own Big Bang event and constantly expanding.

It's a bit like a cosmic "bubble", where each bubble is a universe, and in each of these universes, the basic physical parameters are different, and the physics in our universe is defined by a few different physical parameters, such as the strength of gravity, the strength of atom binding,......。

These parameters may be completely different in different universes, with probabilities almost equivalent to rolling dice, or perhaps in another universe where gravity makes objects repel each other,...... , the speed of time flow is different in different universes,......。 ”

After a pause, Zhou Xing continued: "There is another interesting view called multiverse theory, the narrow sense of "multi-universe theory" refers to the plurality of habitable worlds, that is, the belief that there are many earth-like worlds in the universe, and there will also be intelligent beings living there, so the narrow sense of "multi-universe theory" is also called "multi-world theory".

"Polycosmology" in a broad sense refers to the diversity of cosmic forms, that is, it believes that there are countless independent universes with various characteristics in addition to the total galaxies or "our universe" within the scope of observation, and the "polycosmology" in the broad sense also affirms the existence of intelligent beings in other celestial bodies outside "our universe,......。 ”

You should have mentioned the famous "photon double-slit experiment", in which a photon that is supposed to embody particle properties (such as a bullet) unexpectedly has a wave characteristic (diffraction fringes such as water waves), and according to the final diffraction fringes, this photon passes through two gaps at the same time and interferes with itself, while when the photon is observed with a detector, the photon will appear obviously "particle-like" and will only pass through one gap.

The parallel universe theory believes that when the photon splits into two strands through the gap, the whole universe has been divided, one is the universe where the photon passes through from the right side, and the other is the universe where the photon passes through the left side, yes, the universe with the entire human race and all matter is so easily "split", the whole world is in the split all the time, the so-called continuous universe will not exist, every moment will be the starting point of time, then, "Schrödinger's cat" does not exist The mystery of life and death, after all, it is two universes.

……。

"Based on the above theories, we can already deduce that the universe is not as simple as we imagined, and fortunately, during this interstellar voyage, we met another alien civilization, completed a deal, and gained knowledge about the theory of filling the universe!"

Zhou Xing finally concluded: "Now, I want to put forward another new point of view, I think: in addition to the total galaxy or "our universe" that we observe, there are countless independent universes with various characteristics, that is, each universe is independent, but they are also related to each other, linked one by one through the vein of space-time wormholes, I call this cosmology: 'cosmic tree' theory. ”

Zhou Xing paused his speech, the whole venue was silent, and the reporters looked at Zhou Xing blankly, confused by the profound theory, and couldn't react at once.
