On March 14, Interstellar Year 6, Tiangong officially left the gravitational pull range of Tokta Star, thus officially bidding farewell to Tokta Star.
On this day, Tiangong received a message from its distant homeland—Earth. This was the first message from Earth received since Tiangong left Triton.
Without exception, the messages are transmitted from laser arrays installed on the moon.
The message is divided into three parts.
The first part tells about the numerous natural disasters that have occurred in various countries around the world since the Tiangong left the Earth's orbit in 2160.
In the past six years, the Ebola virus broke out across African countries, killing hundreds of thousands of people. The economies of African countries dropped to freezing point, and countless victims were trapped in an environment of food and water shortages.
Then, the worst wildfires in Australia's history broke out, and the fires were so intense that it seemed like the end of the world was coming.
The fire burned an area of nearly one million hectares, and the fire released more than 400 million tons of carbon dioxide into the atmosphere. This is already the combined annual emissions of more than 100 countries with the lowest carbon dioxide emissions in the world.
The direct consequence is that the global average temperature has increased by 2 to 3 degrees Celsius, the temperature in Antarctica has reached 20 degrees Celsius, and many glaciers have melted, causing sea levels to rise.
Then there is the American influenza. More than 20 million people have been infected across the United States, and nearly 100,000 people have died. The mortality rate is so high that it is really rare.
In the same year, the new coronavirus broke out in China. Although the epidemic was effectively controlled, China's economy also suffered an extremely severe test.
At this time, the locust plague in East Africa swept through more than 20 countries. 400 billion locusts crossed the ocean and reached India and Pakistan, affecting an area of nearly 20 million square kilometers.
During these six years, there were also the eruption of the volcano Mount Fuji, the tsunami caused by the earthquake in Peru, and the sinking of Madagascar.
The second part is that countries on the earth have ushered in the sixth scientific and technological revolution, and have made huge breakthroughs in both the quantum field and new biology.
Among them, the biggest breakthrough in the quantum field is quantum transmission.
Quantum transmission uses quantum principles to ensure that the transmitted information has high confidentiality. A key link in quantum communication is called quantum teleportation.
Quantum teleportation is two entangled particles. If one of them is measured and a result is obtained, then the other particle can know what state it is in without measuring it.
Two entangled particles, the state of each particle corresponds at a distance.
The so-called quantum teleportation is to copy the state of a particle to a particle that is any distance away in principle through entangled particles. The particle itself is not transmitted, only the state is transmitted.
At the beginning of the last century, some Chinese scientists had achieved three-dimensional invisible quantum transmission, that is, the simultaneous transmission of three-state wave functions.
In this technological revolution, quantum computers have once again achieved major breakthroughs.
Different from electronic computers, electronic computers form various information by the arrangement and combination of 0 and 1, and use the so-called quantum superposition state in quantum mechanics.
For example, an electron can be in two different states, 0 and 1, at different conceptual rates at the same time, leading to fundamental differences in algorithms.
The principle of quantum entanglement is also used. Two entangled electrons can represent four pieces of information, namely 00, 01, 10, and 11. That is, two electrons can store four pieces of information.
Three entangled electrons can represent 8 pieces of information, namely 000, 001, 010, 100, 011, 101, 110, and 111. If the number of entangled electrons reaches N, eventually N will be in a quantum entangled state. The electron can have 2 n states.
In other words, while the amount of information increases exponentially, the number of electrons increases linearly, which is 2 to the nth power.
If N equals 20, then there are more than one million pieces of information.
An electronic computer would need more than a million 0s and 1s to store this information, but a qubit only requires 20 qubits.
Therefore, the complexity that traditionally increases exponentially becomes linear in quantum computing. Therefore, what a traditional supercomputer can calculate in 10,000 years is not as large as
The subcomputer can calculate it in a few minutes.
Quantum computers have been studied for a century and have only recently achieved major breakthroughs because quantum bits in an entangled state are extremely prone to disorder and errors.
It's not easy to entangle three electrons, let alone dozens.
The breakthrough of new biology, from a technical perspective, is a "creation and regeneration revolution"; from an industrial perspective, it may be a "bionic and regenerative revolution"; from a civilization perspective, it may be a "regeneration and immortality revolution" ".
In the agricultural era, the major problem faced by mankind is the pressure of survival. Food is the most important thing for people, and its needs are basic needs. The development of science and technology mainly includes agronomy, astronomy and practical technology.
In the industrial age, human beings are faced with ever-increasing material needs for life, which are basic and intermediate needs. The development of science and technology is mainly related to material production, including various disciplines of modern science and technology.
In the knowledge age, human beings have very rich material lives. The pressure they face is mainly to improve the quality of life and meet the needs of spiritual life. Its needs are advanced needs. The development of science and technology is mainly related to the quality of material and cultural life.
Spiritual needs also include health, longevity and traveling in space.
If we say that the focus of science and technology from the 18th to the 20th century was on mankind's understanding of nature, conquering nature, and maximizing the satisfaction of mankind's material life needs.
Then the focus of science and technology in the 21st and 22nd centuries is for humans to understand themselves and change themselves, comprehensively improve the quality of material and cultural life, improve human sustainability, and adapt to the needs of the space era.
In the past 500 years, approximately five scientific and technological revolutions have occurred in the world, including two scientific revolutions and three technological revolutions.
Historical experience shows that global economic crises often spawn major scientific and technological innovations and breakthroughs. Today, some important scientific and technological fields have shown signs of revolutionary breakthroughs, new technological revolutions and industrial revolutions are beginning to take shape, and the world is at the "dawn" of a new round of scientific and technological revolutions.
Life sciences, material sciences, and their intersections emerge.
Because there are so many unknown things in human life and health, there are many big questions that need to be explored, and there are many new theories that need to be established.
The establishment of new theories and their application will greatly improve people's quality of life and existence, and even lead to the emergence of new industries.
Therefore, new biology is not only used in the medical field, but also further improves the average life span and physical condition of humans.
It has also achieved major breakthroughs in the military field.
Regarding the third part of the information, Tiangong did not disclose it to the public and officers and soldiers, so only the first two parts of the information were announced to the outside world.
Fang Mobei sat in the lounge, watching the two parts of the message projected by Sai Hu, and fell into deep thought.
There were also lieutenants and colonels from other departments of the Special Service Brigade in the lounge, but like Fang Mobei, they all looked at the information transmitted from the earth announced by the Tiangong.
For the first part of the information, Fang Mobei had already made some mental preparations. As early as the decades when the Tiangong was under construction, disasters such as earthquakes, floods, and droughts, large and small, had occurred.
Every disaster makes them more determined to face the "Ark", "Zeus" and "Tiangong". Perhaps people have discovered that these disasters are closely related to everyone's life.
But I didn’t expect that in the past six years, viruses, wildfires, epidemics, locust plagues, earthquakes, tsunamis and other disasters have all broken out intensively. I wonder if my hometown is okay at this time.
As for the breakthroughs in the new biology field during the scientific and technological revolution mentioned in the second part, Fang Mobei thought of the research on genes.
The cultivation of genetic warriors discovered in Hogg's base caused Fang Mobei and others to suffer greatly.
Fang Mobei turned off Saihu's projection and looked at the coffee in front of him in silence.
"Lieutenant Colonel, the information related to the Security Department is considered top secret on the Tiangong. With your authority, you are temporarily unable to access more information," Sai Hu said cogently.
"Then forget it." Fang Mobei had long expected such a result.
Will the earth really come to an end
This issue is not just something Fang Mobei is thinking about. I believe that the vast majority of people on the Tiangong are thinking about it when they see the coming
Such thoughts will arise when the first part of the message is transmitted from the earth.
If the earth really comes to an end, they will become the last fire of mankind.
The Zeus has been destroyed, and now there are only the "Ark" and the "Tiangong". While people are feeling lucky, they are also lamenting the future of the mother planet of the Earth.
When Fang Mobei came to the team training room, he saw Gu Yiyi and the others gathered around and talking about something.
"square team"
"The team is coming"
Fang Mobei walked towards the crowd and saw that everyone was holding tablets in their hands. On the tablets were messages transmitted from the earth. Obviously the topic they just talked about was related to these messages.
"How are you training? There's a competition tomorrow," Fang Mobei said as he looked at the absent-minded crowd.
"That's almost it. It just depends on how we perform tomorrow," Gu Yiyi walked to Fang Mobei's side and said.
"Okay, let's all take a rest tonight. We have been training so hard these days," Fang Mobei said to everyone while holding Gu Yiyi's shoulders.
"Team Fang, do you think the earth is really heading for the end?" Qi Jingyu asked with a frown. His parents were still on the earth, and he was obviously a little worried about them.
"Qi, what does it matter if your family is still there or not? Since you left the earth, you can't get together again, can you?" Blake shrugged.
"Jingyu, your family will be fine," Mina glared at Blake fiercely, held Qi Jingyu's arm and whispered softly.
"Hey, don't be unreasonable. There are natural disasters every year on the earth. It's just that there have been more in the past few years. There's no need to make a fuss," Fang Mobei comforted.
"If that doesn't work, just wait a few more years, wait until Interstellar 10 years, and then Tiangong will use a laser array to transmit information to the earth.
If you have anything you want to say to your family, you can pass it along." Gu Yiyi looked at everyone's sad faces and couldn't help comforting her.
"Team Gu, I asked, only school officials and above have this free quota." Qi Jingyu said with an aggrieved look, "Those like us who are not within the quota can only use our contribution points to purchase this quota, which is quite expensive."
"Emmmm" Gu Yiyi smiled slightly awkwardly, "It doesn't matter. I will give my place to you when the time comes. Anyway, I don't have any family anymore."
"Okay, let's disperse." Fang Mobei took Gu Yiyi's waist and the two of them walked towards the door, leaving only everyone looking at each other.
In the dormitory, Fang Mobei was leaning on the bar making coffee, while Gu Yiyi was taking a shower in the bathroom.
Fang Mobei, who had nothing to do, focused on his ears, then groped for the bathroom.
Gu Yiyi wiped herself with a bath towel. Fang Mobei could hear the sound of water and even her breathing.
"I didn't expect you to have such a hobby." Gu Yiyi noticed Fang Mobei's behavior, but did not shy away from it.
"Emmmm" Mobei was caught behind the scenes just like a primary school student who was caught peeking at the seam of a young female teacher's chest.
"Are you so hungry?" Gu Yiyi laughed.
"It's just that you are too beautiful." Fang Mobei shrugged.
"There are no plowed fields, only exhausted cows." Gu Yiyi blew her hair with a hair dryer.
"It's okay, your field has plenty of water and is easy to farm." Fang Mobei raised the corner of his mouth.
"..." Gu Yiyi
Fang Mobei didn't hear Gu Yiyi's voice, so he knew she couldn't continue. Gu Yiyi couldn't even see his taillights when it came to racing.
Perhaps every man is born to be a rider, just like every woman has the potential to be a rider.
Maybe Fang Mobei could have the upper hand in the drag racing car, but when a pair of blue eyes appeared in front of him, he felt a crisis, a crisis coming from below.
Gu Yiyi, who has the physique of a C-level physical practitioner, and some of the genes of a leopard, naturally has more wild needs in some aspects. If Fang Mobei had not already reached the level of a B-level physical practitioner, I am afraid that after a few rounds of battles, Will also be listless.
