The Science Fiction World of Xueba

In 2045 A.D., Ark 1 flew past the Centaur constellation.

In 2049 A.D., the Earth received the Centaur signal from Ark 1, and mankind completed the historic interstellar exploration mission, which caused a global shock. Decades after its departure, the Ark Project once again became the focus of human attention.

At this time on the earth, controllable nuclear fusion has broken through, humans have partially immigrated to Mars and the moon, and large-scale space industry and resource development in the solar system are in progress.

However, the seed released from the earth decades ago has always attracted the attention of all human beings like a gem.

Human beings have launched a protracted debate on whether to launch a follow-up interstellar exploration program.

The opposing side believes that the risk and cost of interstellar exploration are too high, and the resources of the solar system are still far from being developed, so it is of little significance for humans to launch interstellar exploration.

The supporters believe that human beings were able to carry out such magnificent interstellar exploration operations decades ago. There is no reason why human beings have already begun to industrialize space, but they have become timid.

And there is an even more important point.

As a member of human civilization, Pang Xuelin started the first star exploration mission in human history.

This task is promoted purely by Pang Xuelin's own power.

Therefore, supporters believe that human civilization cannot just watch these pioneers die.

It is necessary for human beings to provide support for these pioneers in their follow-up exploration operations within their capabilities, and even send interstellar spacecraft to catch up with them and help these pioneers return to Earth when the technological breakthrough reaches a certain level.

Because of this, shortly after Pang Xuelin and Mu Qingqing completed the detection of the Centaur and went into hibernation, a human star exploration project headed by the United Nations was established on the earth.

Humanity has invested a huge amount of resources into this plan, and the United Nations hopes to complete the integration of the United Earth Government in a sense through this great cooperation among countries around the world.

It's just a pity that by the time the United Nations sent this information, Pang Xuelin and Mu Qingqing had already re-entered hibernation.

By the time the crew on Ark 1 received this information, it would have been 60 years since Ark 1 set off.

Until 2088 AD,

The Ark 1 spacecraft flew past Sirius at 15% of the speed of light. Pang Xuelin and Mu Qingqing woke up again and saw this message.

However, this did not change the Ark One exploration plan.

In 2110 AD, the Ark 1 spacecraft flew past Tianyuan 4 at 20% of the speed of light.

In 2140 AD, the spacecraft Ark 1 passed 79 Cetus at 23% of the speed of light.

In 2209 AD, the Ark 1 spacecraft flew past Alpha Lyra (Vega) at 25% of the speed of light.

In 2212 AD, after completing the observation of Vega, Pang Xuelin and Mu Qingqing went into hibernation again.

And this hibernation is forever.

In two hundred years, Pang Xuelin and Mu Qingqing woke up four times, each time lasting two to three years, and one or two years short.

It stands to reason that the crew still have a long lifespan enough to support them to complete subsequent detection missions.

But Ark One couldn't last that long.

In addition to the successive problems in various systems of the spacecraft itself, the consumption of materials in the spacecraft also exceeded Pang Xuelin's expectations.

According to the original plan, in addition to the ultra-long shelf life space food carried in the spacecraft, some vitamins, protein, cellulose, etc. will be provided by the plant cabin.

However, when the spacecraft flew past 79 Cetus, there was a problem with the plant cabin, and several subsequent repairs failed to fix it.

As a result, the consumption of spaceflight food in the spaceship accelerated.

After completing the detection of Vega, Pang Xuelin and Mu Qingqing had to go into hibernation, waiting for the rescue from the earth.

For Pang Xuelin, this also means the end of China's solar world.

...

In the darkness, a light appeared faintly.

Pang Xuelin opened his eyes in a daze, and the familiar system lottery carousel appeared in front of him.

"Congratulations to the host, you have completed the exploration mission of eight star systems. In view of the outstanding performance of the host in this world, the system will give the host a special reward based on the original reward."

Pang Xuelin was stunned for a while, and said, "System, my mission is completed? How many worlds have I explored? How is the Ark One spacecraft now?"

"The host has explored eight star systems in total. In 2278 AD, the Ark 1 spacecraft was overtaken by a rescue spacecraft launched by human civilization while visiting the star GJ357 (31 light-years away from the solar system). After the rescue spacecraft slowed down, it parked in the star GJ357d. This planet is a living planet with a living environment similar to that of the earth. At present, the increase in entropy within 31 light-years of the solar system has stagnated, and if the host wishes to continue living in the Chinese solar world, the system will restore the string vibration within 31 light-years of the Chinese solar world.”

Pang Xuelin thought for a while and said, "No need, by the way, after all these years, it's almost time to return to the real world. What is the special reward you mentioned just now?"

The system said: "In addition to having eight round trips to the sci-fi world, the host can also bring eight characters from the sci-fi world back to the real world!"

Pang Xuelin couldn't help being slightly taken aback, and suddenly felt a little moved.

If he could bring eight characters from the sci-fi world back to the real world, wouldn't that mean he could let Mu Qingqing go back with him.

But immediately, he had a headache.

Since getting the system, he has traveled through nine sci-fi worlds, namely Three-Body, The Martian, The Wandering Earth, Village Teacher, Whale Song, Dark Forest, District 9, Interstellar, Resident Evil, and the Chinese Sun. I have also experienced several relationships.

Wang Muhui in Country Teacher, Zhuang Yan in Dark Forest, Chris in District 9, Murphy in Interstellar, and Mu Qingqing in China Sun.

Coupled with Yao Bingxia and Qi Xin in the real world, there are two tables of mahjong just short of one.

If Pang Xuelin took all these girls to the real world, Pang Xuelin estimated that his mother would hack himself to death with a knife.

After all, just how to balance between Yao Bingxia and Qi Xin is enough for the mother to have a headache, let alone seven.

Therefore, Pang Xuelin is not blessed to accept this reward in a short time.

Instead, go back to these worlds to visit those old friends, get together with these girls, you can think about it.

Pang Xuelin shook his head and began to focus on the rewards given by the system.

On the roulette, a total of six rewards appeared, namely nano-mirror film technology and deep space sail propulsion technology, nuclear fusion spacecraft engine technology, curvature engine technology, quantum communication technology (quantum entanglement), positive and antimatter annihilation reactor technology, Anti-gravity engine technology.

Pang Xuelin couldn't help being a little surprised.

He did not expect that the various scientific and technological rewards given by the Chinese Sun World system would be so generous.

However, from the rewards given by the system, Pang Xuelin also vaguely saw what kind of height the human science and technology level had reached in 2278 AD.

Curvature engines, matter-antimatter annihilation reactors, antigravity engines, and quantum entanglement communications (which are different from what we often call quantum secure communications) can only show that the Chinese solar world has been The development of these technologies has only been made possible by the rapid progress in the field of basic science.

"The system has given me eight chances to return to various sci-fi worlds. Perhaps, I can take the time to return to these worlds and pack the technology inside and bring them back to the real world."

Pang Xuelin thought to himself.

The progress of basic science is the source of power to promote scientific and technological progress.

The electromagnetic launch aerospace planes, carbon nanotube chips, molten salt nuclear reactors, fusion nuclear reactors, etc. that he is working on in the real world are all based on the results of quantum mechanics and relativity in the early 20th century.

At best, it is an application in the field of engineering.

Of course, basic science and applied science have mutual promotion.

The development of applied science provides an experimental basis for exploring basic science, and the development of basic science further promotes the advancement of applied science.

For example, the emergence of relativity and quantum mechanics provided a theoretical basis for the development of nuclear physics.

Then during World War II, mankind completed the development of the most powerful weapon in history-the atomic bomb.

Subsequent nuclear power plants, silicon-based chips, and the information revolution are all inseparable from progress in the field of fundamental physics.

Pang Xuelin stared at the six technologies on the turntable without blinking.

Nano-mirror film: a lightweight metamaterial with a reflectivity as high as 99.99999%, which has strong application prospects in deep space communications, artificial sun, space power stations and other fields. One of the most important applications can be used as the main material for spacecraft sail propulsion. There are many types of sail propulsion, such as solar sails, laser sails, microwave sails, and particle sails.

Solar sails rely on the light pressure of sunlight to generate thrust, while laser sails use the light pressure of external high-power lasers to generate thrust. Because the laser is much stronger than the sun, the thrust is also high. It is necessary to build a high-power laser infrastructure.

Microwave sails use microwaves with a wavelength much longer than visible light to generate thrust. The principle is similar to the light pressure of electromagnetic waves. Microwave sails can be made of metal wires into a mesh to reflect microwaves. They are lighter and stronger than reflective films of light sails, and the acceleration is also faster. bigger.

Particle sails use magnetic or electrostatic fields to capture high-speed charged particles, such as protons and electrons in the solar wind, or artificially emitted charged particles, to generate thrust. Since those charged particles have mass, and the photon of electromagnetic wave has mass of 0, the natural thrust is greater.

The disadvantage is that the speed of those particles is low. The speed of particles in the solar wind is about 700 km/s-200 km/s, which is not comparable to the photons moving at the speed of light in electromagnetic waves. At the same time, charged particles are easier to diverge than electromagnetic beams, which means Thrust drops off quickly with distance.

Compared with propulsion, sails are much more practical than EM engines, because the spacecraft itself has a relatively simple structure and does not need to carry a high-power power generation system. It can be made very light, and the thrust-to-weight ratio is relatively high, which means higher acceleration.

Nuclear fusion spacecraft engine technology: Through nuclear fusion, the hot, rapidly expanding helium plasma produced by it is ejected at a speed of 100,000 kilometers per second, thereby providing powerful power for the spacecraft.

Compared with solar sails, this technology has greater thrust, a wide range of adjustments, and is flexible and changeable. The only drawback is that it cannot perform long-endurance missions due to the use of working fluids. It can be used for flights within the solar system, especially for applications for military spaceships.

Curvature engine technology: The universe is not flat, but has curvature. If the universe as a whole is imagined as a large membrane, the surface of this membrane is curved, and the entire membrane may even be a closed soap bubble. Although parts of the membrane appear planar, spatial curvature is ubiquitous.

According to the theory of relativity, mass can change the curvature of space, and the change of curvature is uniformly distributed around the mass center of the mass object.

The so-called curvature engine is to create a curvature space (space-time well) the same as the black hole singularity in front of the spacecraft, so that the spacecraft will fall forward quickly.

Theoretically, the maximum speed of the curvature engine can be infinitely close to the speed of light (but cannot exceed the speed of light), but according to the mass-energy equation in the theory of relativity, the engine needs to consume extremely high energy, and only positive and antimatter annihilation reactors can provide such a level of energy.

Quantum entanglement communication technology: In quantum mechanics, when several particles interact with each other, since the characteristics of each particle have been integrated into the overall property, the properties of each particle cannot be described separately, but only the properties of the overall system can be described. Then Call this phenomenon quantum entanglement or quantum entanglement. For quantum entangled particles, no matter how far away they are, even if the two ends of the universe are separated, when the state of one particle changes, the state of the other particle will also change accordingly.

This kind of communication technology can realize ultra-long-distance real-time communication, which is of great significance to interstellar civilization.

Antimatter annihilation reactor technology: The annihilation of one gram of matter and antimatter can produce 1.8×10^14 joules of energy, which is the highest level of energy application form based on the theory of relativity. This kind of reactor has a mass-energy conversion efficiency of almost 100%. Theoretically speaking, the complete annihilation of 500 grams of antimatter is equivalent to the energy produced by the explosion of the world's largest hydrogen bomb. Once this technology is broken through, it can provide a steady stream of energy for human beings to carry out interstellar colonization.

Anti-gravity engine technology: The core of this technology is to manufacture a gravitational wave shielding layer, and wrap the material with the gravitational wave shielding layer, so that no gravitational interaction will occur between the material and the surrounding space. In this way, the gravity of the earth will not Then there are the obstacles for human beings to enter space. Human beings can easily realize the industrialization of space and incorporate a steady stream of space resources into future development.

...

Pang Xuelin's eyes swept over the six technologies one by one. Finally, he took a deep breath and said, "System, let's draw a lottery!"

Soon, the turntable began to rotate rapidly, and two minutes later, the turntable stopped slowly, and the pointer finally aimed at the nuclear fusion spacecraft engine technology.

"Congratulations to the host, you have obtained the technical principle of the nuclear fusion spacecraft engine and the roadmap for the realization of related projects!"
