Chapter 1,173 The Difficulties of Interstellar Navigation

Just because Fen gave up the argument, it didn't mean that Lin ignored her original worry. At least Fen didn't plan to move her steps yet. So Lin asked: "What were you thinking about originally? It couldn't be something related to goblins. Are those little things worth worrying about?"

Fen curled his lips when he heard someone keep saying that he didn't have any, but in fact his remarks were seriously discriminatory. But she didn't want to continue focusing on the goblins, but instead answered someone's question seriously. "Seeing the Gauss Bertone getting ready for sea trials reminded me of a question I've always wanted to ask."

After Fen paused briefly, Lin finally turned his head and looked directly at the beauty in front of him, waiting for the other party to continue asking.

"That's a battleship-level robot. It can adapt to what you call interstellar navigation."

Lin didn't think much and replied directly: "There is no doubt about this. The anti-gravity device integrated with magic and the Vap engine allow them to travel between the stars at speeds exceeding the speed of light. As half-machine, half-magic creations For a robot, the energy source of the machine part can be collected from the countless stars and provided to the nuclear fusion reactor, which is not expensive. Only the magic part must be considered whether it can only be obtained from the mysterious land and its Obtained from the relevant plane world, after how far away from the distance, will the difference in the speed of replenishment and consumption become unbearable. Only by clear research on this part can we truly escape from the lost land, escape from the earth elemental plane, and carry out the so-called interstellar Sailing.”

No matter what level of robot it is, the mechanical part has not yet left Lin's cognition, that is, the result of the earth before someone traveled through it. But the composition of robots is not just mechanical, there is also a magical part. And this idealistic composition, what kind of effects it has and where its limits are are still not fully understood.

"So, after solving the magic problem, you can ask a battleship class, or even a fleet, to send you back to your hometown directly by interstellar navigation. That's right."

Listening to the beauty in front of him and her chilling words, Lin felt as if he had lost something. He didn't know where this feeling came from, but he still replied seriously: "That seems reasonable, but it is not the best choice."

The cold feeling disappeared instantly. Fen opened his eyes wide and asked unexpectedly: "Why?"

"Because it's too far away."

"say clearly."

Faced with this hot and cold attitude, someone was thoughtful. In fact, he has never been someone who doesn't understand the style. But if I have to leave after all, I really don’t know how to settle this nonsense. So someone had to continue to pretend to be stupid and said: "According to my calculations, the distance between Mystery and the Earth is at least 10 million light years. With the current level of the Vapor engine of the robot battleship class, it cannot be achieved in a short time." Such a distance can be covered in time. Then if I want to return to Earth on a robot battleship, I will encounter two situations."

"Which two?" Even though it was purely technical knowledge, Fen wouldn't ask if he wasn't interested in it. But the more knowledge at this popular science level, the better. So I asked.

"First of all, what I want to say is that the robot's Vap engine is not the earth's warp engine in the true sense. In other words, after entering Vap space, the time dilation situation has not been resolved; but such an engine, But it can jump across dimensions. And they don’t see any disadvantages in using it, just because at this stage they don’t need to carry out real interstellar navigation, it’s just very short-distance movement.”

"What does this mean?"

"It means that when they sail close to the speed of light and exceed the speed of light, their own time will slow down, and the disguised external time will seem to speed up. Even if they fly back to the earth, it may be the earth millions of years later. Not the Earth I left. And this is just one of those situations."

"What about the other one?"

"So how long will this journey home take? Even at a speed of warp speed nine or above, it may take decades or even hundreds of years. In other words, it is very likely that it will take me I will never be able to return to Earth in my lifetime. If I take my partner with me to breed and live on a battleship, it may take several generations for my great-grandchildren to reach their destination. If this time is longer, then the people I bring will If there aren’t enough, you’ll have to endure inbreeding in your offspring before any living people can arrive.”

As he spoke, Lin threw out several formulas, tables and graphs. Yifen's mathematical skills are easy to understand at a glance. Lin Cai continued: "Although the technological advancement of battleship-level robots is beyond the reach of even my hometown. Only science fiction stories can find the corresponding level. But if you want to send me home, there is still a long way to go." It’s not enough.”

With a sigh, Lin looked up at the sky and said: "Unless I give up looking for other methods today and just want to send my ashes back. Then it is not impossible to entrust a battleship-level robot to do this. Otherwise it will be me. It is possible that I will arrive on Earth when I am old enough to be about to die. But at that time, humans may have been extinct or degenerated on Earth. The protagonists on the surface will be replaced by a bunch of apes, and then I will see dumped on the coast somewhere. Statue of Liberty. But I probably won’t kneel down and shout ‘No~!’. That is the reaction of the protagonist when he suddenly sees unacceptable facts without knowing it. For me, Such a result can be said to be expected, and there is nothing surprising. Not to mention, there is a greater possibility that the earth has been destroyed by the humans living on it. "

Fen felt more and more strange the more he listened, and his only thought was: "What kind of nonsense is that?"

"Haha." Lin smiled easily. There are some jokes that no one here can pick up on. Maybe this loneliness is what makes me want to go home.

But Fen remembered another thing and asked again: "What about the progress of your flash technique?" What she wanted to ask was exactly how someone originally planned to use the flash technique to directly carry out ultra-long distance teleportation and return to the earth. That method.

Lin shrugged helplessly and spread his hands and said: "The flash technique is two-way. It can not only send things over, but also grab things at the destination. And I have tried to grab the position where the earth should be from the calculation more than once." One cubic centimeter of stuff comes back. But the result is always the same, nothing. Not even air particles, or ion dust that should be filled in the vacuum of the universe. Doesn't this prove that my calculation results are wrong, and the earth is not Not where I calculated it to be.”

Fen pondered for a moment and asked, "Well, what do you think the problem is?"

"My night starry sky can be recognized by the consciousness of the earth, which proves that there is no big problem with the star map I calculated through simulation. But the flash technique requires very precise positioning. The distance between the mysterious land and the earth is so far away that it is calculated to just a few decimal points. One hundred digits is still not accurate enough. So how much accuracy is required and whether there are other auxiliary methods need to be considered. The most troublesome thing is that this ultra-long-distance flash can almost kill me once. Squeeze it dry once. It’s destined that I won’t be able to use it frequently, and even if I want to use exhaustive methods to find the correct position on the earth, I can’t.”

"So, you're not leaving for the time being?"

"I can't leave, okay. I want to go home, not die."

Fen, inexplicably happy.
