After the conversation with Marven ended, the Führer turned his gaze to the other scientific chiefs.

"Several, the empire has some questions I would like to consult you, and I hope you can use the knowledge you have to solve the empire's doubts."

The scientific chiefs paused for a moment, their expressions faintly stunned, and then changed to cautiousness, because the Führer's words were used in the words of the Führer, not himself.

This shows that in the next conversation, the Führer is asking them on behalf of the empire as a whole, and its importance will be directly related to the foundation of the empire.

Under the solemn gaze of several scientific chiefs, the Führer slowly spoke.

"War is about to begin, and just in case, the Empire needs to sow some seeds, with the current technology, can it safely and reliably sail across the stars? I would like to know the feasibility of transstellar navigation. ”

"If it's just a safe and reliable interstellar journey, the Empire already has the technology, it's just ...... That's not going to carry people. ”

The reply was given by Neil, the Empire's chief astrophysicist, who was involved in all the design of the Empire's space vehicles and buildings, and although he could not be said to be at the top in every field, he said that no one dared to say the first and second, and no one present had a better say than him.

"The safety and stability of interstellar navigation is directly proportional to the time of sailing, the longer the voyage, the greater the probability of problems on the way, and the celestial bodies are moving all the time, the slower the speed, the easier it is to lose the destination, so the speed should be as fast as possible, according to my expectations, the safest and most stable interstellar voyage is sub-light speed sailing."

"The Empire can already sail at sub-light speeds?!"

The Führer, who had always remained calm, couldn't help but be moved, not only by him, but also by the other generals, Neil nodded, but shook his head again.

"It's just that it can achieve the sub-light speed of three adults in weight, and it's still not feasible to carry people considering factors such as life support, deceleration, human endurance limits, food, etc."

"I'm curious, how do you do it at sub-light speed? With the Empire's existing propulsion technology, it shouldn't be as efficient as it gets. ”

General Mopsch asked curiously, he couldn't think of any way Neil could do it to travel at sub-light speeds.

Neil shook his head slightly, telling the Führer of his own idea of a sub-light method of sailing.

"The so-called propulsion, in fact, in essence, is still to convert energy into kinetic energy, in such an empty place as the universe, this essence is very obvious, whether it is a shell or a missile, it can be easily intercepted by a laser, change your thinking The difference between sitting on a missile and sitting on a battleship, isn't it just that one will bào zhà the other will not? To sail at sub-light speeds, you don't have to be limited to propulsion engines. ”

"We can use the parent ring as an acceleration orbit to give the emitted object a very high initial velocity at the beginning, and then we can arrange a focusing lens in the stellar orbit and use the pulse beam to accelerate the object that is out of orbit of the ring, and after calculation, the object will eventually leave our galaxy at sub-light speed in the process."

"It's never a question of how to accelerate to sub-light speeds, it's a question of how to slow down, and it's possible to travel long distances between stars, but what about when you reach your destination? How do I stop the projectile? ”

At this time, every general suddenly asked.

"Isn't it okay to use antimatter?"

"No, the mass of the projectile is already such that it can't slow it down on its own, even with the Empire's precious antimatter."

The meeting fell into a brief silence, and the Führer did not speak, his eyes were misty, as if he was thinking about something else.

At this time, someone broke the silence.

"Führer, I have an idea that may solve the problem of slowing down."

A chief science officer spoke to the crowd and explained his plan.

"You can use the gravitational pull from the stars to slow down."

"You mean, that gravitational slingshot accelerates?"

The Führer's eyes fell on the man, a little puzzled by the other party's plan, according to his understanding, the gravitational slingshot is to accelerate the aircraft, but they discussed how to slow down.

"Yes, but you misunderstood, the gravitational slingshot can be accelerated or slowed down, so that the projectile rotates against the celestial body and slows down, and the kinetic energy consumed comes from the rotation of the celestial body, I think with a celestial body as massive as a star, it is completely fine to slow down a sub-light projectile."

For ease of understanding, a projection of the rotation of the reverse planet appeared in front of the Führer.

Looking at the projection, his fingers tapped on the table, and the Führer pondered the feasibility of this slowdown plan.

"But that kind of deceleration, after the projectile arrives at its destination, may continue to slow down for thousands or even tens of thousands of years, and no one can say what will happen in the process."

The chief scientist already had an idea in his mind, and he replied.

"In the process of deceleration, you can gradually shorten the distance with the star, and the greater the gravitational force of the distance, the more obvious the deceleration effect."

"But in this way, the projectile will need to carry fuel, and the mass will undoubtedly increase." Neil reminded from the sidelines.

At this point, another chief of science spoke.

"Führer, in fact, you can also add the light sail technology."

"Lightsail? That product of your light pressure theory not long ago? ”

The Führer's gaze turned to the man, who nodded and replied.

"Yes, the light pressure comes from the star and not the projectile, and the fuel on the projectile can be outlawed by changing the direction of the light sail, only a small capacitor bottle is needed, and at the same time, the light sail can also be used to generate electricity, so that the projectile will not have the problem of power depletion."

In this way, sub-light speed travel between stars finally has a solution that sounds feasible.

However, the 'Imperial Seed' needed more than just sub-light sailing, but also some other technology, and at this time, the Führer, who had half of the big stone in his heart, threw an inquiring look at his sister.

"Marven, how is your hibernation technique going?"

"It is still in the experimental stage, with a success rate of 35%, and it will take some time to ......"

"That is, it can be put into use, and 35 percent is enough."

Without waiting for Marven to finish speaking, the Führer interrupted her speech, the success rate can be made up by people, the last thing the empire lacks is people, the longer it drags on, the more accidents happen, and it is best to implement the seed plan as soon as possible.

Sub-light sailing, light sailing, hibernation, cloning, AI ...... The Führer spliced these technologies together in his mind, and the seed plan of the empire gradually took shape.

"The last piece of the puzzle of the seed is also considered to be collected, and if there is anything missing, it should be...... A suitable person. ”
