Ye Han rushed to the Beiyuezhou headquarters, knocked on the door and entered Wu Han's office: "Commander, are you looking for me?"
"Sit!" Ye Han pointed to the chair opposite the desk and threw a document on the table, "Let's take a look."
Ye Han sat down, took the file, opened it, and immediately saw a photo of a star: "What is this?"
Wu Han gestured to Ye Han to turn to the next page. After Ye Han did so, he found that it was a high-definition star map with a particularly bright star on it.
Wu Han pointed at the photo: "Do you recognize it? This is the brightest one."
Ye Han shook his head: "I don't recognize it."
"This is Sirius."
"Oh, I know, I've heard of it." Ye Han nodded.
"Do you understand?" Wu Han asked again.
Ye Han shook his head again: "I don't know very well. I just know that there is a white dwarf star near Sirius."
He didn't tell Wu Han that this was because he liked to read miscellaneous books when he was a child. In the book, he saw that although the Mayan civilization was not particularly advanced, its understanding of the sky was far superior to other civilizations. For example, they knew that Sirius had a dark partner.
From that moment on, he remembered that Sirius was a binary star system.
Wu Han nodded: "Yes, Sirius is a binary star system. Our research team discovered something on Jupiter. According to these records, Jupiter once stayed in Sirius for a period of time!"
"No way?" Ye Han was completely surprised, "Isn't that a double star? The astronomical environment is much more complicated than that of a single star. There can't be habitable planets, right?"
"There is nothing impossible. Aliens are not us humans. Their survivability is so strong and their environmental requirements are not that high. Moreover, they can use superb biochemical technology to transform planets. They can survive in such a harsh environment on Jupiter's moon
, can the Sirius environment be as good as these places again?"
Ye Han frowned and said: "Commander, do you mean that aliens have a colonial star on Sirius?"
"Yes!" Wu Han nodded solemnly.
Ye Han's expression gradually became heavy: "Commander, the reason you came to me is..."
"How can we allow others to sleep peacefully on the side of the bed!" Wu Han's expression was extremely solemn, "We have already suffered an invasion, and we will never allow a second invasion!"
Ye Han was stunned: "You mean, the higher-ups are preparing to go on an expedition to Sirius?"
Wu Han nodded heavily: "This is destined to be an expedition with no return, but we know where they are, and they also know that Europa is coming here. If aliens develop on Sirius, one day in the future
Will definitely attack the solar system!"
At this point, Wu Han sighed: "We cannot leave the war to future generations."
Ye Han already had a premonition in his heart and asked dryly: "Commander, what do you mean by coming to me..."
Wu Handao: "You know both land and air combat, and have commanded a fleet. You are the most suitable candidate, so..."
"Commander, please stop talking, I understand." Ye Han looked bitter.
Wu Han said sincerely: "Some things must be done by someone. Due to the special nature of this mission, we only need volunteers. If you are not willing, we will find someone else."
Ye Han whispered: "What should I do with my family?"
"This is both an expedition and a colonization, so you can bring your whole family with you."
"Take it with you?" Ye Han didn't know what to say, "The distance to Sirius seems to be 8.6 light years, right?"
"right!"
"This is not 8.6 astronomical units. How can we fly there? Using Europa?"
"No, use an immigration fleet." Wu Han said, "The higher ups are planning to build a real immigration fleet."
"How fast can the immigration spaceship reach?" Ye Han asked the most critical question.
Wu Handao: "There is no accurate data yet. According to the above plan, the immigrant fleet must fully accelerate before leaving the solar system. It will use all available planets to accelerate. When the speed is fast enough, it will leave the solar system again!"
"Make full use of it?" The biochip in Ye Han's brain quickly calculated, "Based on the basic speed of 60 kilometers per second, the acceleration of Venus is 70 kilometers, the earth is 60, Mars is 48, Jupiter is 26, Jupiter is 19... It takes three seconds per second.
More than 100 kilometers, which is 9.4 billion kilometers per year... Commander, it takes a thousand years to fly one light-year, 4,000 years to fly to Proxima Centauri, and 8,600 years to reach Sirius. This, this, this, even if it is double
Hibernation can’t last that long, right?”
It takes more than 8,000 years to fly. Are you kidding me?
The history of human civilization is only more than five thousand years. Eight thousand years ago, human beings were still struggling in primitiveness and ignorance. Eight thousand years later, what level will human beings develop to?
Ye Han, who was full of troubles, forced a wry smile: "Commander, I dare not say anything else, but I think if aliens really develop there, before our colonial fleet flies to Sirius, the aliens will
Humans will definitely reach the Earth first. It is also possible that the human race in the solar system will be extinct before the fleet is even halfway through. Is such a nonsense expedition meaningful?"
Wu Han sighed: "Yes, you are right. It is not easy for human beings to reach today. But it is precisely because human beings may become extinct one day in the future that we should get out of the earth and spread the seeds. Even if the earth is in the future
Destruction, the extinction of human beings on the earth, at least the seeds of human beings are still there. As long as the seeds are still there, there is still hope for human beings."
Ye Han's face twitched: "Maybe before the fleet reaches Sirius, humans will build a faster-than-light spacecraft and get to Sirius ahead of the immigration fleet."
"This possibility is not impossible, but I believe that I will not be able to see that day. If you join this plan, it is still possible to see it." As he said this, Wu Han showed a surprised expression and looked at Ye Han.
As if looking at a retarded person, "Also, how did you calculate 8,600 years? You didn't calculate how long it would take for a super battleship to fly one light year while continuing to accelerate? Why is the basic speed 60 kilometers?"
Ye Han was a little confused. After thinking for a while, he scratched his head and said, "I made a mistake!"
The reason why the basic speed is set to 60 kilometers is because this is the highest speed per second that the Lone Wolf flies over, but that is because the battleship must enter the deceleration program halfway through the distance, not because the battleship cannot continue to accelerate.
He immediately re-entered the data and quickly came up with a new result - the average acceleration of the super battleship is 0.23-0.25 meters per second. Taking 0.23 as the calculation, theoretically it only takes nine years to fly one light year!
Seeing this result, the expression on Ye Han's face suddenly froze: "No way, it's only nine years?"
He didn't know much about physics and only knew the simplest physical formulas, but the simpler it was, the easier it was to calculate. He checked the entire calculation process several times and found no mistakes.
