This result really surprised Ye Han. With some curiosity and some expectation, he put in the data and continued to calculate. After the super battleship continued to accelerate for two years, the speed could reach 15,000 kilometers per second, which is twice the speed of light.
One tenth!
In other words, the super battleship only needs to continue to accelerate for 12.8 years to fly a distance of two light years. It only takes more than a hundred 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 the halfway point of the voyage!
Of course, continuous acceleration requires an astonishing amount of fuel. Be it a super battleship or an immigrant ship, it will definitely not be able to carry that much fuel. It is impossible to continue accelerating for more than ten years. So what about continuing to accelerate for one year?
He plugged in the data again, and the result was that after a year of continuous acceleration, the battleship could reach a speed of more than 7,000 kilometers per second, and it would take 41 years to fly one light-year... Well, this time is a bit long, and it would take 360 years to fly the entire distance.
Many years, but this data is much faster than 8600 years.
Ye Han hesitated and said, "The result I calculated is between 350 and 360 years. Counting acceleration and deceleration, it's about 400 years."
"What do you think?" Wu Han said with a smile on his face, "Can you accept it?"
Ye Han grinned: "Commander, this is not about whether I can accept it, but whether the immigrants can accept it."
He counted on his fingers: "A person can last up to seven days without eating, and only three days without drinking. Although hibernation can reduce human metabolism, the reduction does not stop after all. Even if it is reduced by four hundred times, every thousand
It is necessary to resuscitate once every 200 days to restore the body and replenish nutrients. It is not possible to continue hibernating until the body is well. If it is not double hibernation, 400 years of hibernation is equivalent to one year in reality. Calculated by reviving every seven days, everyone must wake up halfway.
52 times..."
He also wanted to talk about double hibernation. Although that thing can further reduce the metabolic rate, this method of hibernation is too dangerous. The death rate is close to one in ten. Moreover, the longer the hibernation time, the higher the death rate. This method is really used.
After 400 years of hibernation, only one immigrant in a hundred survives.
But waking up 52 times in the middle seemed not much more. Ye Han couldn't continue talking in the middle of the sentence. He could only swallow the double hibernation thing, found another topic and continued: "Commander
, since it is an immigration fleet, there must be people, right? How many thousands of people are planned to immigrate? "
"Not sure yet, but definitely indispensable."
Ye Han immediately became energetic: "Commander, interstellar immigration is a one-way ticket. It will definitely not work if there are fewer immigrants, and it cannot support a civilization. If we immigrate 100,000 people, how much food will be consumed along the way? And on the way, how much food will be consumed?
Consumption is still a small problem, what about after arriving at Sirius?"
"We simply don't know to what extent aliens have developed in Sirius. Let's simply assume that there should be four situations for aliens there. One is that they are developing well and have even begun to expand outwards; the other is that they are still developing.
Yes, there is space power but it is not strong; third, civilization has degraded and there is no space power at all; fourth, the aliens left there are completely extinct. No matter which situation we encounter, the situation we have to face is different.
"
Wu Han signaled Ye Han to continue, and Ye Han took a breath and said, "If it's the first situation, then we absolutely can't bring immigrants there. The most we can do is send a few warships there, but only a few ships will definitely be useless. It's best to stay put."
.”
"The second and third situations are slightly better. You can bring immigrants, but you cannot revive the immigrants before defeating the aliens. Once our fleet loses, the immigrants must evacuate immediately. They must not fall into the hands of aliens under any circumstances!
"
Wu Han nodded involuntarily. As a senior military official, he knew very well the consequences of humans falling into the hands of aliens.
"The last situation is the most ideal situation. The aliens have become extinct, leaving behind a habitable planet. As long as our immigrants land, they can establish settlements, gradually expand outward, and finally completely occupy the planet...
…But the possibility of this happening is very small. I personally think that the first scenario is the most likely!”
"Also, although Sirius is 8.6 light-years away, we don't know if aliens have special communication methods. Maybe the aliens staying there already know the situation in the solar system. Maybe the aliens there
We have begun to form a fleet for expedition to the solar system!"
The corner of Wu Han's mouth twitched: "You kid, just say it if you don't want to, don't make so many excuses!"
"Commander, you must know that what I said is the truth!" Ye Han said righteously, "When the aliens came, we were still a planetary race, but when we get to Sirius, the aliens may stay on the planet obediently
Wait until we get there? Of course it’s impossible!”
Before Wu Han could speak, Ye Han added: "There is a more important question. With our current technology, interstellar migration will take hundreds of years at every turn. Can our warships and spaceships withstand the aging of so many years?"
Ye Han's words simply poked Wu Han's heart, but Wu Han had to answer: "We are trying to solve this problem. As long as it is properly maintained, it shouldn't be a problem."
"What about the weapons?" Ye Han asked again, "The half-lives of uranium-235 and plutonium-239 are long enough, and hundreds of years are not a big problem, but the half-life of tritium is only twelve years. When the fleet arrives, only the atomic bomb will be left.
The hydrogen bombs have all become dumb. We only rely on low-yield nuclear weapons, laser cannons and naval guns. Do you think we can defeat the aliens?"
Wu Han waved his hand: "Not only are you aware of these problems, but the higher-ups are also aware of them. The higher-ups are studying ways to solve them. I believe that when the immigration fleet is built, these problems will be effectively solved!"
Ye Han hesitated for a moment, but still couldn't hold it back: "I still feel that now is not the time."
Wu Han sighed helplessly: "The superiors also know that now is not the time, but can we afford to wait? We have already been invaded by aliens once. If it happens again, can we withstand it?"
Ye Han wanted to say yes, but he knew very well that there would be too many surprises for humans to defeat aliens. If it were to happen all over again, humans might not have the last laugh.
Wu Han continued: "We do still have many problems that have not been solved, but as I said just now, the superiors are trying to find a way. If we really can't develop a better engine, we will put a few super engines on a ship.
On the spaceship, everyone can think of ways to speed up... I think four to five hundred years is the limit acceptable to the higher ups. No matter how slow it is, the higher ups won't be able to agree to it even if you want... So don't rush to make a decision, go back and think about it carefully.
For a moment, it’s best to discuss it with your family before deciding, that’s it.”
