Chapter 69: Explore the stars thousands of years in advance
When Zhang Jingyuan walked into the conference hall of the satellite research department, almost all the important elderly people in the expert company had already arrived. A middle-aged scientist was explaining his ideas in a daze; even Zhang Jingyuan didn't even notice it. When Zhang Jingyuan came in, one-third of the progress bar for watching the video had passed. And behind Zhang Jingyuan, there were people coming one after another.
Zhang Jingyuan has an impression of the people above, as if they were among the experts who went to Germany before the Earth was unified. However, after so many years, I have seen too many people and experienced too many things. Even Zhang Jingyuan has blurred too much because he did not have a special memory.
Gradually, Zhang Jingyuan also heard a little. This is a brand new concept of detector launch, a concept, not a new technology. But sometimes we have to say that technology is just the foundation, and how to apply technology is the concept guiding! Of course, we cannot deviate from the essence of technology.
But in just two minutes, Wang Nannan came in, followed by Li Bing, Li Guoyi's grandson, and Li Xinyu's younger brother.
"Papa..." Wang Nannan clapped his palm gracefully. When everyone saw it, he opened his lips lightly: "Mr. Chen, everyone is here, and I have seen your ideas too; but these big guys don't know. I can only ask you to tell me again."
"Minister Wang, this is my honor." The middle-aged man nodded slightly.
At this time, Zhang Jingyuan remembered that the person in front of him should be Chen Xingping. No, it depends on his age. Chen Xingping should be Chen Xingping's son. Chen Xingping was an excellent welder who returned from Germany. He was about 20 years old at that time. After more than 40 years of experience, ordinary workers had to make certain contributions even if they wanted to come into contact with cultivation. Therefore, the person in front of him should be Chen Xingping's son; but it was really similar to the face in Zhang Jingyuan's memory.
"Hello leaders. My name is Chen Feng, and I am the son of Chen Xingping, the top welder in the empire. What I am explaining today is that we should explore places outside the solar system in advance, and thirty years, three hundred years or even thousands of years in advance. Please listen to me one by one.
First of all, although the solar system is very large, in fact, we have basically explored almost all over the years. Apart from a few planets, there is nothing left, empty. As for the dark matter that accounts for 97% of the mass of the universe, we are powerless now.
In addition, the solar system is too small in the universe. Since we have entered the space age, the next interstellar era will inevitably be put on the agenda.
But my idea is different from the general idea, and I think mine is right. Many people say that it will take at least 30 years to build a powerful technology; therefore, some people say that we will concentrate our efforts on developing space technology in thirty years. But I think we need to start exploring the world outside the solar system now.
30 years may be long, but we have been around for eight years. On the other hand, what we cannot avoid is that the super-large space environment. Even the speed of light needs to be calculated based on years. Assuming that we now have an aircraft that reaches one-tenth of the speed of light, it will take 42 years to reach the star system closest to us, which is the centaur constellation. However, this is a binary star system. Because the instability of the binary star system has led to such a binary star and even multi-star system, it is difficult to have a foundation for life; even transformation is basically impossible. Therefore, for us, such a galaxy is not very meaningful. As for mineral resources, there are Kuiper Belts and Olt Clouds around the solar system, and some are resource celestial bodies. Therefore, since this centaur star system is not suitable for habitable and cannot be transformed, and there are no resources we need, it is meaningless to explore such a place. At least for the time being, it is meaningless.
Then, the next Barnard star is 6 light years away from us, Woolf 359 stars 7.7 light years, Brand 2147 stars 8.2 light years, UV star Whale 8.4 light years, Sirius 8.7 light years, Ross 154 stars 9.5 light years, Ross 248 stars 10.4 light years. Bojiang ε star 10.8 light years, Ross 128 stars 10.9 light years... Forget it, the larger the range, the more stars around it. But according to recent observations and clear evidence, it is the distance between us
The 12 light-year-old whale constellation T star, here we observed a planet suitable for life, and it is basically confirmed that there will be life on it; recent observations show that there may be clouds on this planet. After more than a year of observations of more than 2,000 artificial and probes, it can basically be determined that there will be life on this planet; of course, we cannot determine the form of life and whether there are advanced life. The advanced life we call refers to life forms with brain tissue.
If we want to explore the T-star of the whale constellation at close range, if we start to launch the probe now and emit one tenth of the light, it will take 120 years for the detector to arrive. Oh, this is the chronology of the earth; if it is Venus, then we need to wait 156 years. Then, the exploration signal needs to be returned, which is another 12 years of the earth.
Starry sky exploration, the author is to be lazy, cough cough... For unit unit unification, we still use the time unit of the earth. After all, there are too many interstellar observation data on the earth over the past century, and it is inconvenient to change the unit. Moreover, it can be foreseen that with the development, the future starry sky time will inevitably be varied, and we need a standard now.
In addition, we have another weakness in communication. The maximum range of superstring communication devices in space is only 1.5 billion kilometers, and this obviously does not work much in the universe that is often calculated in light years. If we want to enter space, we must have more advanced communication technology. In other words, we have to set up base stations for superstring communication devices in space. However, I calculated that the cost is enough to make us collapse. Within a light year, about 80 million base stations need to be set up to barely line up to transmit information. According to the cost of near-ground base stations of 10 million, the cost price increases by 1% for every far away. So the final number is sorry I didn't calculate because it has no meaning anymore. Anyway, it is not enough to tie the earth and Venus together to bear this cost. Well, it should be about 50 billion yuan.
Of course, today I am not talking about communication technology, but about it. We should explore now. The scale of space is too large, and we must plan for the next hundred years and millennium in advance!
Space is not inside the planet. The plane will arrive in a few hours. In space, there is no time for any temporary plan! You should know that even if we go to a centaur constellation, it takes 42 years to calculate at a rate of one tenth of a light-year! To make temporary plans, the information transmission time will take 4.22 Earth years, and we will receive feedback again, which will take about 8.5 years! At this time, no plan will be useful!
So, I think we should make arrangements for the future now. Therefore, I designed a detector launch device. The technologies used are all our existing technologies, and some of them are even borrowing from the labor results of others. But I can only say that this is the lowest cost and the most feasible interstellar detection method at present.
First of all, according to the mass-energy formula m=M÷(1-v^2÷c^2)^2, we can know that when the speed of an object is close to the speed of light, the greater the speed, the greater the mass. The reason is still unclear. It should be that advanced cosmic laws are at the action.
According to my rough calculations, an interstellar exploration probe must have powerful capabilities - and modern times still use electricity. Therefore, I recommend using micro-technical mature nuclear fission technology. As far as I know, we should now master those nuclear fission technologies in the palm."
"I know this." Li Yuzhang, who has been in charge of energy research at this time, stood up. As a core member of the expert company, he is over 70 years old, but he still looks energetic. "We have not improved the handheld nuclear power plant you mentioned recently. It is nuclear fission technology. As for nuclear fusion, sorry. Now they have a diameter of 100 meters and require a lot of sea water to cool.
In addition, the most reasonable thing about the handheld nuclear power plant is a 30 cm diameter that can work continuously for 50 years and output 10 degrees of electricity per hour; and it is very stable and safe, and is a mature product. It is about to be mass-produced and will be used as an energy source for future space communications, various small detectors, and satellites.
Now, when meeting space needs, the minimum diameter can be ten centimeters, output one kilowatt-hour electricity per hour, and working time for 10 years; the maximum is one meter. It can be adjusted, and the maximum can reach 500 kilowatt-hour electricity per hour, and working for 60 years; the minimum can be adjusted to 10 kilowatt-minute points, and working for 200 years. The subsequent hardware aging will not be continued after two hundred years.
Well, there is also a weight. The weight of 30 cm is about 90 kilograms, and the nuclear fuel is relatively heavier. The weight of one meter is 17 tons. Give us another year, and 30 cm size will be able to automatically adjust the power output life and may continue to be extended. In terms of measurement of time units, in order to unify the Earth's calendar. There is too much information in scientific research, so we can only continue to extend the time on the Earth.
But I am worried that ten or a hundred years of exploration in space are not enough.”
"Thank you." Chen Feng bowed slightly, "If this happens, we will use 30 cm nuclear fusion. It will output 10 degrees of electricity per hour, which should basically meet the needs of space probes.
In this way, an interstellar probe with good functions has a designed weight of about 200 kg. We calculate it based on 200 kg.
My plan is like this. Use a super-combined electromagnetic rail to launch the detector. This rail is not the length we usually see, several thousand meters, but thousands of kilometers, or even tens of thousands of kilometers.
Using guide rails, we speed up the detector as much as possible and then launch it out of the solar system. As the detector moves forward, we use solar sails to accelerate the detector.
There is no resistance in space, which allows us to design the solar sails large enough within a reasonable range. Using nano-film technology, we can design a solar sail with an area of tens of thousands of square meters, and the weight can be controlled within 30 kilograms.
Then, we used the space mirror to gather enough sunlight and transform it into parallel sunlight beams to illuminate the sun sails, and continue to accelerate the detector.
We already have several high-intensity films that are resistant to high temperatures. However, there is one thing that needs to be paid attention to here. This film needs to reflect as much as possible. In this way, light and reflection will provide two thrust. Otherwise, a large amount of light will be absorbed, and at high speed movement, the absorbed energy will be converted into mass under an unknown mechanism. This is something we don't want to see.
Using the phenomenon of constant speed of light, in theory, we can accelerate the detector to infinitely close to the speed of light. Of course, this does not mean anything to us. Scientifically, we will never vigorously explore things that do not make much sense.
But theoretically, as long as the sunlight continues to be in full swing, the detector can be accelerated. However, considering the complex space environment, the solar sail will lose its function. Therefore, we will enable nuclear power plants at this time to provide forward power and energy for instrument work.
However, the specific speed and so on still need to be calculated. After I personally calculate, I tend to finally accelerate to 0.7 times the speed of light, and use 0.7 times the speed of light as a standard for our universe exploration. Because at about 0.7 times, the mass of matter will double. An object of one kilogram of mass will become two kilograms. However, on small detectors, this change is acceptable.
If the speed of light is 0.7 times, it will take about 17 years for the detector to reach the whale constellation T star; it will take 12 years for the signal to return. Considering the various complex problems of the universe, it will take about 30 Earth years and 39 Venus years before we can receive the feedback signal from the detectors we are currently launching.
This time, the time spent on the acceleration process has not been calculated.
Also, I want to say that such detector launch technology can only be regarded as the basis. If it needs to be expanded in the future, it can be expanded as a way for spacecraft to accelerate."
Many people frowned when they heard this, so they forgot to clap their hands and congratulate them. The reality is so bad that no one expected it; to be precise, no one dared to think about it! Because this is too damaging to people.
Originally, I felt that I was very powerful. You see that the technology is so advanced, far exceeding that of the Earth's colleagues. But now, when I took out the specific numbers, I found that I had taken the exam. According to the current technology, it would take more than 40 years to go to the nearest centaur constellation - or one-way. If the signal transmission time is added, it will take 45 years! How many 45 years in life! Ordinary people can live for two 45 years, that is truly longevity!
For a moment, the scene was a little calm, or depressing. Only Chen Feng was silently demonstrating and explaining his expected animation. The guide rails that lasted tens of thousands of kilometers had a pair of wings every hundred meters - that was a photovoltaic cell; there were a total of 100,000 pairs of electromagnetic guide rails, like a dragon in space; the error of any point of the entire guide rail was almost zero, with a diameter of about one meter. If it was larger, the magnetic field would be dispersed, resulting in reduced technical efficiency of the guide rails and severe heat.
