Yip hon shook his head "don’t know"

"This is Sirius"
"Oh know heard of" yip hon nodded.
"Do you understand?" Wu Han asked again
Yip hon shook his head again. "I don’t know clearly that there is a white dwarf near Sirius."
He didn’t tell Wu Han that when he was a child, he liked to watch Maya. Although he was not particularly advanced, he knew far more about heaven than others. For example, they knew that Sirius had a dark partner.
Since then, he has remembered that Sirius is a binary system.
Wu Han nodded. "It’s a binary system for Sirius. Our research group Io found something. According to these data, we recorded that Io had stayed with Sirius for a while!"
"No way?" Yip hon all surprised "that place is not a binary star? The astronomical environment is much more complicated than a single star. It is impossible to have a livable planet? "
"Nothing is impossible. Aliens are not human beings. They are not so productive and have low requirements for the environment. Moreover, they can also transform the planet Europa with superb biochemical technology. The environment is so bad that they can give birth to Sirius. Can the environment be worse than these places again?"
Yip hon frowned. "Commander, you mean that the alien Sirius has a colonial star?"
"Yes!" Wu Han nodded solemnly.
Yip hon expression gradually heavy "commander, you came to me to mean …"
"Do others sleep peacefully on the side of the couch!" Wu Han’s expression is more dignified. "We have already suffered an invasion, and we are absolutely not allowed to appear again!"
Yip hon was shocked. "You mean to prepare for an expedition to Sirius?"
Wu Han nodded heavily. "This is destined to be an expedition to return, but we know where they are and they know that Io is coming here. If the alien Sirius develops, it will definitely attack the sun one day!"
Speaking of this, Wu Han sighed, "We can’t leave the war to our grandchildren."
Yip hon heart already had a hunch dry asked "commander, you want to see me …"
Wu Han said, "You know both land warfare and war, and you have commanded the fleet …"
"Commander, you don’t say I am white" Yip hon a face of bitterness.
Wu Han said earnestly, "Some things have to be done by someone. We need volunteers. If you don’t want to, we will find someone else."
Yip Han whispered, "What about my family?"
"This is an expedition and a colony. You can take your family with you."
"belt?" Yip hon doesn’t know what to say. "The distance to Sirius seems to be 6 light years, right?"
"Yes!"
"It’s not six astronomical units. How can we fly there? Io? "
"No immigrant fleet" Wu Han said "We are going to build a real immigrant fleet"
"How fast can the immigrant spacecraft reach?" Yip hon asked a key question.
Wu Han said, "There is no accurate data yet, and the immigration fleet must be fully accelerated before leaving the sun. When is the speed fast enough to leave the sun!"
"Full profit?" According to the basic speed of 6 kilometers per second, the acceleration of Venus is 7 kilometers, that is, Earth 6, Mars 4, Jupiter 26 and Jupiter 19 … At the very most, one second is more than 300 kilometers, that is, 9.4 billion kilometers a year … Commander, it takes 1,000 years to fly a light-year and 4 years to fly to proxima centauri and 6 years to Sirius. Can this, this, even double hibernation not last that long?
One flight is a joke for thousands of years.
The history of human literature is more than 5 thousand years ago, and human beings struggled in reduction and ignorance. What level will human beings develop after a thousand years?
Yip Han barely gave a wry smile. "Commander, don’t I dare not say it, but I think if aliens really develop there, they will definitely kill the earth before our colonial fleet flies to Sirius. It is also possible that the fleet will be extinct before it has flown half of the sun. Is it meaningful to make such an expedition?"
Wu Han sighed, "Yes, you said that it is not easy for mankind to go today, but it is precisely because human beings may become extinct one day in the future that we should go out of the earth and spread out our species. Even if the earth is destroyed in the future, there will be hope if fewer human species are extinct."
Yip hon face sobbed, "maybe before the fleet to Sirius, human beings will build a ftl ship first, and rob the immigrant fleet to Sirius."
"This possibility is not without, but I believe I won’t see that day. If you join this plan, it is still possible to see it." Said Wu Han with a surprised expression, looking at Yip hon’s eyes is like looking at a mentally retarded person. "And how did you figure out this six years? Haven’t you calculated how long it takes for the super battleship to fly a light year when it continues to accelerate? What is the basic speed of 6 kilometers? "
Yip Han-nao was a little puzzled before he scratched his head. "I thought it was wrong!"
The base speed is set to 6 kilometers because this is the highest second speed that the lone wolf flies, but that is because the warship must enter the deceleration procedure halfway, rather than the warship cannot continue to accelerate.
His horse re-substituted the data and soon got a new result-the average acceleration of the super warship is 2325 meters per second, and the calculation theory takes nine years to fly a light year!
Seeing this result, Yip Han’s face froze. "No, it’s only nine years?"
He doesn’t know much about physics and knows the simplest physical formula, but the simpler it is, the easier it is to calculate. After checking the whole calculation process several times, he didn’t find any mistakes.
Chapter 1954 Theory for four hundred years
This result is really a surprise for Yip Han with a little curiosity and expectation that he will put the data in and continue to calculate the super battleship. After two years of continuous acceleration, the speed can reach 15 thousand kilometers per second, which is one-twentieth of the speed of light!
In other words, the super battleship needs to continue to accelerate for 12 years, and it will take more than 100 years to fly to Sirius, which is much faster than he expected.
And this is not the limit. The super battleship can continue to accelerate until it is halfway through the voyage!
Of course, continuous acceleration requires an amazing amount of fuel. Super warships or immigrant ships can’t carry that much fuel. If you continue to accelerate for more than ten years, you can’t do it for one year.
He substituted the data again, and the result was that after a year of continuous acceleration, the speed of warships could reach more than 7,000 kilometers per second, and it would take 41 years to fly a light year … er, this time is a little long, and it will take more than 360 years to fly, but this data is also much faster than six years.
Yip hon hesitated and said, "I figured out that the result is three hundred and fifty to three hundred and sixty years, that is, four hundred years of acceleration and deceleration."
"What do you think?" Wu Han smiled. "Can you accept it?"
Yip hon grinned. "Commander, this is not whether I can accept it, but whether immigrants can accept it."
He snapped his fingers and counted that "people who don’t eat or drink for up to seven days will hibernate for three days. Although it can reduce the metabolic rate of human beings, it can be reduced. After all, it is not to stop, even if it is reduced by 400 times, it must be revived every 1,200 days to replenish nutrition until the body is well. If it is not double hibernation, hibernation for four years is equivalent to a year in reality, and everyone must wake up 52 times in the middle …"
He also wants to say that although the double hibernation can further reduce the metabolic rate, this hibernation mode is too dangerous, and the death rate is close to one in ten, and the longer the hibernation, the higher the death rate. This method is really different for immigrants who hibernate for four years.
But waking up 52 times in the middle seems to be not much. Yip hon said he couldn’t go halfway. He could swallow the double hibernation and find a new woman to continue saying, "Since the commander is a member of the immigration fleet, he must be indispensable, right?" How many tens of thousands of people plan to immigrate? "
"I’m not sure yet, but I’m sure it will be."
Yip Han-ma is full of energy. "Commander, interstellar immigration is a one-way ticket. If there are fewer immigrants, it will definitely not work. It can’t support an article. Suppose that we immigrate to 100,000 people. How much supplies does this passerby consume? And the consumption on the way is still a small problem after arriving at Sirius? "
"We don’t know at all how far the alien Sirius has developed. Simply assume that there should be four situations in an alien side. First, it has developed well and has expanded outward; Second, development can be too powerful but not strong; Third, the root of literary degeneration has little power; The fourth is to leave the aliens there completely extinct. No matter which situation we encounter, the situation we have to face is different. "
Wu Han motioned for Yip hon to continue Yip hon to breathe a sigh of relief and said, "If it is the first case, then we must never take the immigrants there. At most, we should send a few warships there, but there are definitely nothing. It is better to stay put."
"The second and third situations are slightly better, but immigrants can’t be revived before defeating aliens. Once our fleet loses, immigrants must evacuate immediately. If they can’t fall into the hands of aliens!"
Wu Han involuntarily nodded at the top of the military. He knew very well what would happen if human beings fell into the hands of aliens.
"The last situation is the most ideal situation. Aliens are extinct, leaving a livable planet. If immigrants want to land, they can build settlements and gradually expand outward and finally occupy the planet completely … but this situation is very unlikely. I personally think the first situation is the most likely!"
"And Sirius is 6 light years away, but we don’t know if aliens have any special means of communication. Maybe aliens stay there and already know about the sun. Maybe aliens there have formed an expedition to the sun fleet!"
Wu Han sobbed at the corner of his mouth. "If you don’t want to, just say, don’t look for so many reasons!"
"Commander, you must know that I am telling the truth!" Yip hon righteously "when aliens come, we are still a planetary race, but when we arrive at Sirius, aliens may stay on the planet and wait for us in the past?" Of course it is impossible! "
Without waiting for Wu Han to speak, Ye Han added, "There is a more important question. Our current technology, interstellar immigration, is always hundreds of years. Can our warships and spacecraft stand up to so many years of aging?"
