The Wandering Planet

Qiao Li's impassioned speech at the hearing of the WallFacing Project restored the fighting spirit of mankind, and the plan to build more than 10,000 high-energy accelerators was also approved by the WallFacing Project Committee.

It's a pity that human civilization is still facing a huge problem. Water droplets have crossed the orbit of Saturn and are rapidly approaching the earth.

In the face of real threats, it's not something that can cheer people up again.

How to deal with water droplets has become the most urgent problem facing Qiao Lv.

Conventional weapons are definitely ineffective. The Death Star's super laser cannon cannot destroy strong interaction materials. The destruction of the United Fleet also proves the strength of water droplets.

Qiao Lv's plan can only be implemented smoothly if the threat of water droplets is removed.

It is of course impossible for human civilization to do so at present, and Qiao Lv has to show some of the scientific and technological strength of the wandering earth. Of course, the extent to which it is revealed is the key point that needs to be considered.

He used telepathy to connect to a psychic on the wandering earth, and he was able to communicate with the people on the wandering earth through him.

Sophon couldn't even see through human thinking, so naturally he couldn't detect Qiao Li's telepathy.

On the Wandering Earth, the United Government is repeatedly studying the picture of water droplets destroying more than 1,300 star-class warships in the United Fleet in the Battle of Doomsday.

Although the existence of the sophon has made some psychological preparations for the strength of the Three-Body Civilization, the appearance of the water droplets still surprises people.

However, this is only a probe of the Trisolaran civilization, which shows how big the gap in strength is!

Luo Feng looked at the United Fleet that was exploding like firecrackers in the screen, and said in disbelief:

"Why can a civilization that can't even advance at the speed of light, or even break away from its home planet, have such strong technological strength?"

"Because the environment of civilization is different." Ding Yi explained, "This kind of technology tree is certainly very weird to us, but what about a normal technology tree? As human beings, we can only Judging alien civilizations based on their own history, but ignoring the huge changes brought about by the development of science and technology in different environments."

He further asked: "For example, if there is no iron ore on the earth, to be precise, the iron content is not so abundant, what would the technology of human civilization be like today?"

This is really unimaginable. Iron making is a very old technology, and steel is the foundation of modern industry.

If human beings have never entered the Iron Age, does it mean that technology will stagnate forever and cannot be further developed?

Obviously not like this, it's just that with the development of human civilization in this way, the technology tree may not know where it will go.

"It's hard to imagine, right, but planets with scarce iron ore resources abound in the universe. If civilizations are born on such planets, how can we measure their technological level with the history of mankind?"

Even on the same planet, the development process of civilizations in different regions is very different. Not to mention the difference between civilizations that are not on the same planet at all, and often separated by tens of thousands of light years!

Ding Yi continued: "What's more, the situation of the Three-Body Civilization is even more complicated than the above examples. Its plane is completely different from the world we have experienced before. The universe we see now is a high-dimensional civilization war. The ruins left behind cannot perform space travel, which makes it difficult for the Trisolaran civilization to observe changes in the curvature of the universe.

It is impossible to further research the superluminal spaceship. "

"Let's put it this way, if the basic science and technology of human civilization is locked by sophons, then the technology of Trisolaran civilization is also restricted by higher-level civilizations in another way. This kind of blockade even It wasn't deliberate, just like a nuclear war suddenly broke out on the earth, and a small country was unfortunately affected and turned into a wasteland."

Ding Yi described a more cruel cosmic path. In the eyes of humans, the Trisolaran civilization, which is already so powerful that it defies the sky, is just a primitive tribe that has just been re-established in this wasteland of the universe.

The advanced civilization that launched a war and turned the entire universe into a threat has not been seen until now!

"Should we be worried about this?" Luo Feng asked.

"No, thinking about it now is just unfounded worry. Let's think about how to deal with the Three-Body Civilization first."

The situation of the Wandering Earth is not much better than that of the Three-Body Civilization. If the opponent is a primitive tribe, then the Wandering Earth has not even formed a primitive tribe, and just picked up a few guns by luck...

The psyker who communicated telepathically with Qiao Li walked into the conference room. It was as if he was participating in a teleconference through the body of the psyker. Of course, the whole process was silent.

Luo Feng asked: "Qiao Lv, is that you?"

"That's right, it's me." Qiao Li replied, of course through the mouth of the psyker.

Such a remote meeting method is extremely rare.

"Then Dr. Ding Yi, have you researched the weakness of water droplets?"

When he said this, Qiao Lv felt that it was strange. The person who studied water droplets in the original book of Three-Body Problem was also named Ding Yi, and he didn’t know if the two Ding Yi who are the same body in different time and space would produce quantum energy when they met. Entangled or something.

No matter which side Ding Yi is on, they all have a deep understanding of the structure of water droplets.

After Qiao Lv asked, Ding Yi immediately replied:

"According to the picture of the destruction of the United Fleet, it can be concluded that the general structure of the water droplet is composed of a large number of dense metal-like atomic nuclei in the outer layer under the strong interaction force field, which wraps the internal artificial intelligence computer, strong interaction force generator, and thrusters for compressing electron rain, 12 sets of space force field engines for sharp turns, etc. Its shell is controlled by the internal force field generator, and it is composed of a layer of strong interaction force material with normal density, so the water droplet The mass is only about as heavy as a truck, and Mantis's robotic arm can easily grab it."

"Then how do we destroy it?"

Ding Yi replied: "It's very simple, unlike the ultra-high-density strong-interaction material used in the earth cannon, water droplets essentially use a special force field to change the atoms bound by the electromagnetic force to the strong-interaction force. .So as long as the energy density is high enough to dismantle the atomic nucleus, the 'bond' between the atoms that make up the water droplet can be broken. It can be said that it is not indestructible, but human technology has not reached this point."

"For example, the strong interaction force material projectile fired by the earth cannon can withstand the super laser cannon of the Death Star until it is destroyed. The water drop must consider whether the energy of the force field generator is enough. In fact, the most terrifying part of the water drop is not In terms of structural strength, its propulsion method is the biggest trouble at present."
