The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 315 The Battle of the Lightspeed Spaceship

Jiang Yu's mission was far beyond the expectations of Rey Diaz and He Shanqi. He Shanqi simply asked the doubts in his heart: "Light speed spaceship?"

Rey Diaz thought briefly and said: "I see, as you said just now, the No. [-] civilization can be seen everywhere in the universe, and the Trisolaran civilization is more like a backward civilization than the No. [-] civilization." civilization.

"We are no match for such a backward civilization, so naturally we have to leave a way out for ourselves: run!"

Jiang Yu nodded with a smile: "That's the truth."

He Shanqi sighed: "On the scale of the universe, human beings are so weak!"

Jiang Yu said helplessly: "For a long time, human beings' powerful self-awareness has come from the earth.

"Humans are indeed kings on Earth, but they are just 'Kangtou Kings'."

Jiang Yu saw that Rey Diaz didn't understand what "Kangtou King" meant, so he changed the term to express it.

Jiang Yu and Rey Diaz usually communicate in English, and the official language of the solar system country is Chinese. Since the simultaneous translator is available, scholars like He Shanqi can't speak English anymore.

Now the conversation between the three people needs to use a simultaneous translator, otherwise He Shanqi would not know what Jiang Yu said to Rey Diaz, and Rey Diaz would not know what Jiang Yu and He Shanqi were saying.

Jiang Yu doesn't know much about Rey Diaz's homeland, but now it seems that people there shouldn't sleep on kangs, at least Rey Diaz didn't.

He Shanqi was born on Mars, so he doesn't even know what a kang is.

This cultural misunderstanding made the atmosphere of "Blind Spot No. 1" a little easier.

He Shanqi said: "I'm not questioning the Wallfacer's plan, I just think it's not feasible."

Seeing Jiang Yu waiting for his further explanation, he cleared his throat and continued: "Theoretically, there are three types of light speed spacecraft.

"The first is to master the mysteries of the time dimension and go directly to 'outside time'. For external observers, this spaceship runs at the speed of light.

"The second is to use the fourth dimension to 'cut the corner'. We can imagine that if we draw a circle on a piece of paper, theoretically it will be difficult for the two-dimensional creatures inside the circle to go outside the circle.

"However, when the two-dimensional creatures in the circle master the method of entering the three-dimensional, they can easily jump from the third dimension, from inside the circle to outside the circle.

"The same is true for us in three dimensions. The distance from one point to another in the universe seems very far away to us, but this distant feeling may be the illusion given to us by the 'drawn circle'.

"The distance between these two points may be very close in four dimensions. As long as we master the way of using four dimensions, some distant distances will become close at hand for us.

"The third way is to use acceleration to travel at the speed of light. This way is the only way we have a chance to achieve it now, but it consumes a huge amount of energy.

"It may be possible to collect all the energy of the solar system, but it may not be enough to consume a light speed fleet.

"These three methods believe that even those who are not majors in physics should understand that the first and second methods are impossible to achieve now, and the third method is also very difficult.

"That's why I said that it is too early to talk about light-speed spacecraft in terms of current technology."

Rey Diaz followed up and asked: "Then how long will it take for us to study the light-speed spacecraft from now on?"

Obviously, he also immediately realized the importance of the light-speed spacecraft. Jiang Yu can be sure that Rey Diaz doesn't know such things as "two-way foil".

But he is keenly aware that the light speed spaceship may be the safest way for human beings to escape from the attack of advanced civilization.

As long as some people can escape, "the green hills will be left without worrying about no firewood".

He Shanqi frowned and said: "I estimate it will be about two centuries, and the first century is used to theoretically determine how to build a light-speed spacecraft, that is to say, to determine a feasible direction.

"In the second century, apply theory to technology, and after many experiments, it is possible to obtain a light-speed spacecraft."

Jiang Yu sighed, Yun Tianming is worth the money here, he saves the time of groping for the human light speed spaceship business!
Thinking of this, he smiled and said, "What if I give you directions?"

He Shanqi and Rey Diaz looked at Jiang Yu in horror and surprise.

Jiang Yu asked He Shanqi: "Haven't you ever thought about a curvature spaceship?"

He Shanqi frowned and said: "For now, curvature is only a theoretical concept, and no evidence of its existence has been found in the universe until now, let alone using curvature to create light-speed spacecraft."

"I know the concept of curvature." Rey Diaz asked with some doubts, "But how to use curvature to reach the speed of light?"

He Shanqi gave an example: "For example, if we draw a midline on a piece of paper, and place a dot at the same position on the left and right sides of the midline at five centimeters each, then the distance between these two points will be ten centimeters.

"But when we fold the paper in half based on the midline, then the distance between the two points is infinitely close.

"However, one thing to note is that in theory, the speed of the curvature spacecraft has been called the 'pseudo-light speed', because the use of curvature navigation does not produce time dilation.

"For example, if we want to go to the Trisolaran galaxy four light-years away, if it is a real light-speed spacecraft, we will arrive there in an instant.

"However, the curvature spacecraft did not break the dimension of time. When it arrived at the Trisolaran galaxy, it was already four years after the Trisolaran galaxy, so it was called the 'false speed of light'."

Rey Diaz said: "This is a bit like the second light-speed spaceship you mentioned just now."

He Shanqi shook his head: "It's different. The curvature spaceship is made to get the shortest distance from one point to another, and the shortest distance in the four-dimensional world is there. As long as you find it, you can use it."

Jiang Yu said something amazing again: "The following conversation is top secret and cannot be disclosed to the fourth person!"

Seeing He Shanqi and Rey Diaz nodded solemnly, Jiang Yu said to He Shanqi: "Have you ever thought about it? Siwei no longer exists!"

He Shanqi smiled and shook his head: "Whether it is the theory of relativity, quantum mechanics, or the just-started string theory, it all proves that the macroscopic universe we live in is a four-dimensional universe.

"It's just that we, as three-dimensional creatures, are born unable to perceive the existence of the fourth dimension."

Jiang Yu said: "Didn't you guys never find a way to use the four dimensions?"

"But they exist in theory. In many places, only by calculating the constant of the fourth dimension, the calculation results are consistent with the results we observed." He Shanqi explained seriously:

"Besides, we have confirmed the existence of dark matter by using the particle accelerator around Jupiter. It is now generally believed in the academic circle that dark matter is a kind of matter in the fourth dimension."

Jiang Yu doesn't understand these things very well, he can only tell what he knows: "Dark matter may be the 'remains' of the fourth dimension after the fourth dimension falls to three dimensions...

"Well, 'remains' might not be the exact word, but that's what it means."

　Thanks to [Mo Ling king] and [Yuan] for their 100-point reward.
