I believe that any kind of intelligent life in the universe will have the desire to trace back to its origin. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Human beings, as representatives of the earth's civilization, will certainly have such deep thoughts and a strong desire to unravel the mystery of their own origins.

"Will we have a chance to see the 'Creator'?" Durunik muttered to himself suddenly.

"We may not necessarily have a chance, but the humans of Earth should have a chance." Yuan Haochen's answer to this question contains both hope and regret.

"I really wish I could live for hundreds or thousands of years......"

Durunik, who has always been optimistic, became sad after listening to Yuan Haochen's words, and he naturally understood the meaning of Yuan Haochen's words.

Indeed, the lifespan of human beings of a hundred years is like a blink of an eye under the large scale of time and space in the universe.

Relative to the vastness of the universe, we are all short-lived, and the more a person knows the value of time, the more he feels the pain of losing time.

For such a short-lived personal life course, and such a low level of science and technology, it is simply wishful thinking to catch up with the footsteps of the Creator.

"Don't be so pessimistic, although we may not be able to keep up with the footsteps of the Creator, but we may still have the opportunity to visit the birthplace of the Creator's technological civilization, which is the hometown of the Alien Doctor." With a smile on his face, Hara comforted him by putting his hand on Durunik's shoulder.

"Based on the information we have now, will we be able to locate the home planet of the Alien Doctor?" When Durunik heard this, he instantly came to his senses again.

"I've talked to Team Leader Frank before. The final verdict is yet to be confirmed, but we already have a clear clue. Yuan Haochen continued very confidently, "In the memory fragment of the Genesis 8 artificial intelligence, the alien doctor mentioned that their planet is about 4 light-years away from the solar system. ”

"About 4 light-years ......," Durunik muttered as he quickly thought about all the eligible star systems, "Centauri A (consisting of three stars) is about 4.4 light-years from the solar system, Barnard, a red dwarf 5.963 light-years away, Wolf-359 is 7.783 light-years away, Canis Major A (Sirius A) is 8.583 light-years away, and Canis Minoris A (South River A) is 11.402 light-years away......"

"Of the 50 stars in the vicinity of the solar system, there are three stars of the size of the Sun:

1. Centauri A (apparent magnitude -0.01, absolute magnitude 4.38, surface temperature 5790K, mass 1.1, radius 1.23);

2. Canis Major A (Sirius A, apparent magnitude -1.46, absolute magnitude 1.42, surface temperature 9940K, mass 2, radius 1.71);

3. Canis Minora A (Nanhe IIIA, apparent magnitude 0.38, absolute magnitude 2.66, surface temperature 6650K, mass 1.5, radius 1.86);"

"So, judging all things considered, the most likely should be Centauri A star A !!" Durunik came up with the most likely answer after deducing from several sources.

Yuan Haochen didn't say anything about Durunik's conclusion, but just smiled and nodded in agreement.

"Centauri A-star!" Durunik was stunned for a moment, then shook his head and sighed.

"Durunike, what the hell are you doing today, haven't you Americans always been full of self-confidence?"

Hara complained that he felt that Durunik was too pessimistic.

"Centauri A is made up of three stars, and even the closest star to Earth, Centauri A C (Proxima Centauri) is 4.22 light......-years away," Durunik couldn't help but sigh when he thought of this.

"Here we go again!!"

"According to the maximum flight speed of the traditional power system of the Starship spacecraft, it will take at least several thousand years to reach Centauri A from Earth. So, we don't have a chance to get to the alien doctor's hometown at all. Durunik shook his head and said.

"We need to be confident that although our capabilities are still limited, in a few years, the new technology will be greatly improved. Science and technology are always evolving! Yuan Haochen comforted.

"In this Mars scientific exploration operation, the nuclear pulse propulsion system has performed very well, and I also believe that the nuclear pulse propulsion technology will be improved in the near future, but it is still difficult to reach Centauri A." Trunik's mood calmed down a little, he thought for a while, and began to continue to calculate, "According to the Institute of Aeronautics and Astronautics, if the technology is stable, and the nuclear fuel is sufficient, and considering the long-term acceleration range of astronauts, our flight speed can theoretically reach 10%~20% of the speed of light, then it will take at least 22~45 years to reach Centauri A, even if there are sufficient supplies on the spacecraft to allow us to survive for more than 40 years, when we reach our destination, has become an old man, and it is estimated that he will never return to Earth in his lifetime. ”

Indeed, according to the technical information provided by the Institute of Aeronautics and Astronautics and the Institute of Nuclear Power, if the manned factor is not considered, the spacecraft of the Interstellar Exploration Alliance can be filled with 1/3 of the mass of nuclear fuel, and all the nuclear fuel energy matrix can be released within a month, and the spacecraft can reach the highest theoretical speed - 10~20% of the speed of light, but this does not take into account the nuclear fuel consumption required to slow down and return home when reaching the destination.

However, if you want to make a manned interstellar trip, you will encounter more and more complex problems, such as the following key problems that must be solved:

First, the acceleration should not be too fast, a month of continuous acceleration to the maximum speed must be unbearable for astronauts, the cumulative time of acceleration should be extended to at least 1~2 years, and can not be carried out continuously, each acceleration should be reserved in the middle of some rest and buffer time (this can be properly solved, but at the same time it also means that the time of interstellar travel should become longer);

Second, it is necessary to ensure the safe and stable operation of the nuclear pulse propulsion system during the long space voyage, and to eliminate the possible harm to astronauts caused by nuclear radiation and the high heat generated by nuclear radiation (the Interstellar Exploration Alliance has initially solved this problem, but how to preserve the safe and stable operation for more than 40 years will be a greater challenge). ）；

Third, during this long journey, the astronauts need to eat, drink, and lazar, and a large number of supply and life support systems will greatly increase the weight of the spacecraft, which in turn restricts the speed of the spacecraft (the current hibernation technology is not mature enough to guarantee the health of astronauts in a long-term low-consumption sleep state, and 40 years of food supply will be an astronomical amount. ）；

Fourth, in addition, astronauts are bound to have various physical and psychological problems during their long interstellar travel, which are all factors that must be fully considered.
