Magic Tower Starry Sky

Fen gave up arguing, but it didn't mean that Lin ignored her original worry. At least Fern wasn't about to move her feet just yet. So Lin asked: "What were you thinking about? It can't be something related to goblins. Those little things deserve your attention?"

Fen curled her lips when she heard a certain person keep saying that she didn't have one, but in fact it was seriously discriminatory. But she didn't want to continue to focus on the goblin, but seriously answered someone's question. "Seeing that the Gosperton is preparing for sea trials, I remembered a question I've always wanted to ask."

Fen paused for a short while, Lin finally turned his head, looked directly at the beauty in front of him, and waited for her to continue asking.

"That is a battleship-class robot, which can adapt to what you call interstellar travel."

Lin didn't think much, and replied directly: "There is no doubt about this. The anti-gravity device combined with magic, and the Wap engine allow them to travel between the stars at a speed exceeding the speed of light. As a half-machine, half-magic creation The robot, the energy source of the machine part can be collected from the innumerable stars, and provided to the nuclear fusion reactor, which is not expensive. Only the magic part, whether it can only be obtained from the magical place and In the relevant plane world, when the distance is far away, whether the speed difference between replenishment and consumption becomes unbearable. This part of the research is clear, so that we can truly get rid of the lost land and the earth element plane, and carry out the so-called interstellar Sailing."

No matter what level of robot it is, the mechanical part has not yet escaped Lin's cognition, that is, the result of someone's earth before crossing. But the composition of the robot is not only mechanical, but also the magic part. And this idealistic composition, what kind of effect it has, and where the limit is, are still not fully understood.

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

Listening to the beauty in front of him, the indifferent words that made people feel chilling, Lin felt as if he had lost something. He didn't know where this feeling came from, but he replied seriously: "It seems reasonable to do that, but it is not the best choice."

The feeling of coldness disappeared in an instant, and Fen opened her eyes wide, and asked unexpectedly: "Why?"

"Because the distance is too far."

"say clearly."

Faced with this hot and cold attitude, someone was thoughtful. In fact, all this time, he has not been an incomprehensible piece of wood. But if I want to leave after all, I really don't know how to calculate this nonsense. So someone had no choice but to play dumb and said: "According to my calculations, the distance between Midi and Earth is at least ten million light-years. With the level of the current robot warship-level Wap engine, it is still impossible to do it in a short period of time." Such a distance can be crossed in time. Then, if I want to return to Earth on a robotic battleship, I will encounter two situations.”

"Which two?" Although it is purely technical knowledge, the part that Fern is not interested in will not ask. But the more knowledge of this popular science level, the better. So ask.

"First of all, I want to say that the warp engine of the robot is not the warp engine of the earth in the true sense. That is to say, after entering the warp space, the condition of time dilation has not been resolved; but such an engine, But they can jump across dimensions. And they don’t see any disadvantages in using it, just because they don’t need to do real interstellar voyage at this stage, it’s just a 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 external time in disguise will seem to speed up. Even if they fly back to the earth by then, it may be the earth millions of years later, Not the Earth I left on. And that's just one of those things."

"What about the other one?"

"That's the journey home, how long will it take? Even at a speed above warp nine, it may take decades, or even hundreds of years. That is to say, it is very likely that I will In my lifetime, I will not be able to return to Earth. If I take my partner and live on a warship to multiply and live, it may take several generations before my great-grandson can reach the destination. If this time is longer, then the people I bring will be If there are not enough, you have to endure the inbreeding of offspring to
