The Science Fiction World of Xueba - Chapter 485

In 2045 AD, the Ark One flew three stars in Centauri.

In 2049 A.D., the Earth received the Samsung Centauri signal returned by Ark One. Humans completed the historic interstellar exploration mission, triggering global shocks. The Ark plans to become the focus of human attention again decades after its departure.

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

However, the seed that was released from the earth dozens of years ago has always attracted the attention of all human beings like a gemstone.

Mankind has launched a protracted debate on whether to launch a follow-up interplanetary exploration program.

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

The supporting party believes that humans can carry out such a magnificent interstellar exploration operation decades ago. There is no reason that humans have begun the industrialization of space, but they have become fearful.

And there is one more important point.

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

This task was driven purely by Pang Xuelin.

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

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

Because of this, shortly after entering the hibernation after Pang Xuelin and Mu Qingqing completed the exploration of Samsung Centauri, a human star exploration program led by the United Nations was established on the earth.

Mankind has invested a huge amount of resources in this plan. The United Nations hopes to complete the integration of the United Earth Government in a sense through this global cooperation.

It is only a pity that Pang Xuelin and Mu Qingqing have re-entered hibernation by the time the United Nations sent this information.

It was already sixty years after the crew of the Ark One received this information.

It was not until 2088 AD that the Ark Spacecraft flew Sirius at 15% of the speed of light, and Pang Xuelin and Mu Qingqing woke up again, only to see this information.

However, this has not changed the Ark One exploration plan.

In 2110 A.D., the Ark spacecraft flew at Tianyuan 4 at the speed of 20%.

In 2140 A.D., the Ark One flew at 79% of the constellation Whale at the speed of light of 23%.

In 2209 A.D., the Ark One flew at 25% of the speed of light to alpha (Vega).

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

And this time hibernation is forever.

In two hundred years, Pang Xuelin and Mu Qingqing have awakened four times, each lasting two to three years long and short one or two years.

It stands to reason that the crew have a long life enough to support them to complete the subsequent detection tasks.

But Ark One couldn’t last that long.

In addition to the successive problems with the spacecraft’s various systems, the material consumption in the spacecraft also exceeded Pang Xuelin’s expectations.

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

However, there was a problem with the plant cabin when the spacecraft flew 79 Whale, and subsequent repairs failed to repair it.

So the consumption of space food in the spacecraft accelerated.

After completing the exploration of Vega, Pang Xuelin and Mu Qingqing had to enter hibernation, waiting for the rescue of the earth.

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

…

In the darkness, a faint light appeared.

Pang Xuelin opened his eyes blankly, and a familiar system lottery turntable appeared in front of him.

“Congratulations to the host for completing the exploration missions of eight stars. In view of the host’s outstanding performance in this world, the system will give the host a special reward based on the original reward.”

Pang Xuelin stayed 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 explored a total of eight star systems. In 2278 AD, the Ark One spacecraft was caught up by the rescue spacecraft launched by human civilization while visiting the GJ357 star (31 light years from the solar system). After the rescue spacecraft slowed down, it was docked into the GJ357d star. The planet is a life planet and has a similar living environment to the earth. At present, the entropy increase within 31 light years of the solar system has stalled. If the host hopes to continue living in the Chinese solar world, the system will restore the string vibration within 31 light years of the Chinese solar world. “

After thinking for a while, Pang Xuelin said, “No, yes, after all, after so many years, it is almost time to return to the real world. What special reward did you just say?”

The system said: “In addition to having eight round trips to the science fiction world, the host can also bring eight characters from the science fiction world back to the real world!”

Pang Xuelin couldn’t help but stunned a little, suddenly a little emotional.

It is possible to bring the eight science fiction world characters back to the real world. Isn’t it that he can let Mu Qingqing follow him back.

But then, he had a headache.

Since getting the system, he has traversed a total of nine science fiction worlds, namely three bodies, Mars Rescue, Wandering Earth, Village Teacher, Whale Song, Dark Forest, District Nine, Interstellar Crossing, Resident Evil, Resident Evil, Chinese Sun, in I have experienced several relationships.

Wang Muhui in the village teacher, Zhuang Yan in the dark forest, Chris in the ninth district, Murphy in the interstellar crossing, and Mu Qingqing in the Chinese sun.

Coupled with Yao Bingxia and Qi Xin in the real world, they are close enough to make up two tables of mahjong.

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

After all, how to play balance between Yao Bingxia and Qi Xin is enough for mother and adult, let alone seven.

Therefore, this reward Pang Xuelin was blessed in a short time.

Instead, return to these few worlds to visit those old friends and get together with these girls, you can think about it.

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

A total of six rewards appeared on the roulette, namely nanomirror membrane technology and deep space sail propulsion technology, nuclear fusion spacecraft engine technology, curvature engine technology, quantum communication technology (quantum entanglement), positive and negative material annihilation reactor technology, Anti-gravity engine technology.

Pang Xuelin couldn’t help being surprised.

He did not expect that the various scientific and technological rewards given by the system would be so rich.

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

Curvature engine, positive and antimatter annihilation reactor, antigravity engine, and quantum entangled communication (unlike the quantum secret communication we often say) can only explain the Chinese solar world, more than two hundred years after the departure of Ark One, With the rapid progress in the field of basic science, it is possible for mankind to complete the development of these technologies.

“The system gave me eight opportunities to return to the major science fiction worlds. Perhaps, I can take the time to return to these worlds and bring the technology inside back to the real world.”

Pang Xuelin was secretly worried.

The progress of basic science is the driving force behind the advancement of science and technology.

The electromagnetic launching space planes, carbon nanotube chips, molten salt nuclear reactors, fusion nuclear reactors, etc. that he is working 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 engineering.

Of course, basic science and applied science have a mutually reinforcing role.

The development of applied sciences provides an experimental basis for exploring basic sciences, and the development of basic sciences, in turn, pushes forward applied sciences.

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

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

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

Pang Xuelin stared at the six techniques on the turntable without blinking his eyes.

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

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

Microwave sails use microwaves with a longer wavelength than visible light to generate thrust. The principle is similar to the light pressure based on electromagnetic waves. Microwave sails can be knitted into a mesh with metal wires to reflect microwaves. It is lighter and stronger than Guangfan’s reflective film, and the acceleration is also Bigger.

Particle sails use magnetic fields or electrostatic fields to capture high-speed charged particles, such as protons, electrons or artificially charged particles in the solar wind, to generate thrust. Since those charged particles have mass, and the photon mass of the electromagnetic wave is 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 / sec-200 km / sec, which is 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 The thrust drops quickly with distance.

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

Nuclear fusion spacecraft engine technology: Through nuclear fusion, the hot, high-speed 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, wide adjustment range, and flexibility. The only defect is that it is because of the use of working fluids. There is no way to perform long-endurance flight missions. It can be used for internal flight of the solar system, especially for applications. Yu military spaceship.

Curvature engine technology: Universe space is not flat, but there is curvature. If the whole universe is imagined as a large film, the surface of this film is curved. The entire film may even be a closed soap bubble. Although parts of the membrane appear to be flat, the curvature of space is still everywhere.

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

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

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

Quantum entanglement communication technology: In quantum mechanics, when several particles interact with each other, since the characteristics possessed by each particle have been integrated into a whole property, it is impossible to describe the properties of each particle individually, only the property of the whole system, then This phenomenon is called quantum entanglement or quantum entanglement. However, no matter how far away the particles are, there is no matter how far apart, even if the state of one of the particles changes across the universe, the state of the other particle will change accordingly.

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

Anti-matter annihilation reactor technology: one gram of omni-matter and anti-matter annihilation can produce 1.8 × 10 ^ 14 Joules of energy ~ www.mtlnovel.com ~ This is the highest level of energy application form based on relativistic conditions. In this type of reactor, the mass-energy conversion efficiency is almost 100%. In theory, the complete annihilation of 500 grams of antimatter is equivalent to the energy produced by the largest hydrogen bomb explosion in the world. Once this technology is breached, it will provide an endless stream of energy for human 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 the material and the surrounding space do not have any gravitational effect, so that the gravity of the earth will not Then there is the obstacle for mankind to enter space. Mankind can easily realize the industrialization of space, and incorporate the steady flow of space resources into future development.

…

Pang Xuelin’s gaze swept through these six technologies, and finally, he took a deep breath and said, “System, draw!”

Soon, the turntable began to rotate quickly. Two minutes later, the turntable stopped slowly, and the pointer finally pointed to the technology of the fusion spacecraft engine.

“Congratulations to the host, for obtaining the technical principles of the nuclear fusion spacecraft engine and the roadmap for the implementation of related projects!”
