The fleet is sailing in the universe, as for what planet to go to, what trade to carry out, and what cooperation agreement to sign, Bai Lian does not care, as the master explained at the beginning, her job is to do a good job in the management of the spaceship, and then report to him from time to time.

As a mental model, she still has a lot of free time, and Bailian often gets bored.

"Good morning, master, today the fleet is sailing normally, 10 million kilometers away from the Moon and is expected to arrive on Mars in 5 days. Master, is there nothing to do? ”

Bai Lian asked, Cao Chuan checked the information she returned, now, not only the digital city, the digital battlefield, but also the entire map can be regarded as connected to the digital starry sky, and the points of light represented by the three spaceships are directly presented in the three-dimensional solar system map to intuitively understand the movements of the spacecraft now.

"Aren't you going to play games with Nana?" Cao Chuan said that there are really few entertainment activities for mental models, such as Nana and Bai Lian, and the more common entertainment activities are watching TV, movies, comics, novels, and watching news on the Internet, which is even more homely than him.

"Of course, if you don't like it, you can also sing..."Cao Chuan thought about it and decided to entrust the responsibility of the virtual singer to Bai Lian's hands, saying that Bai Lian's psychological age is no more than 15 years old, which is theoretically the age of good deception.

"Singing?" Bai Lian expressed a puzzled tone, "Is there anything good about singing?" ”

"Don't you think it's nice to have a lot of people like you?" Cao Chuan continued to abduct.

"But it's too shameful for me to do it." Bai Lian refused again, blinked, and decided to go to Nana.

He saw that Bai Lian was planning to interrupt the communication, and he didn't want to let go of such a precious opportunity, such a big delay, resulting in the possibility of instant chat no longer existing in the universe, and if he had the opportunity, he had to say it all.

"Wait, before we finish the debriefing, call Researcher Matasse over."

Half a minute later, Researcher Metase appeared on the screen, and behind him was a special chamber inside the Hengyue-class ship, which looked neat and bright, giving it the feel of a laboratory.

In fact, it is indeed used as a laboratory by researcher Matasse, who was a researcher at the Sudbury Observatory and has been working on neutrinos for 20 years.

Neutrinos were discovered half a century ago, it is a special elementary particle that makes up atoms, neutral does not contain electric charge, the mass is only 1/10,000 of the electron, and the biggest feature is the terrible penetration.

If a beam of neutrinos were hit on the Earth, it would enter from the North Pole, through the crust, the mantle, the core, and from the core, mantle, crust, until it exited the South Pole, with an energy loss rate of less than 1 in 10 billion.

Therefore, if neutrinos are used for communication, it still cannot solve the increasingly serious delay problem between the universe, but it is possible to solve the signal attenuation, solve the communication between the lunar surface and the back of the moon, and solve the communication problem between the moon and the asteroid belt, and always maintain perfect communication quality.

"Mr. Advisor, the neutrino generator has been built." Metase said to him with great antiquity, because it will be the first meaningful neutrino communication experiment in human history.

The previous time was about 10 years ago, scientists used particle accelerators to create neutrinos, and then through encoding equipment, the information was stored in neutrino beams, and at the same time, a special neutrino receiving device and decoding equipment were also needed to realize the entire process of communication.

At that time, scientists allowed neutrinos to penetrate a 240-meter-thick rock wall and successfully received the information carried by neutrinos, but just like fusion energy reactors, it is not surprising that any pre-research on any advanced technology is carried out in the laboratory, and it is really difficult to put it into practice, even if it is to the initial application.

Surrounded by fusion energy reactors, the massive device with a total volume of nearly two or three chambers is the one they now use to generate neutrinos, which sustain the production of neutrinos through the infinite power provided by the reactors.

And this is the core of the whole neutrino communication technology, where the bottleneck lies, a relatively lightweight, inexpensive neutrino generator is the treasure that scientists dream of, is Cao Chuan spent 1 day to simulate the rules, combined with the research results of Matasse for decades, and walked in the forefront of the times.

"In that case, let's hurry up and experiment." Cao Chuan urged, he also participated in the research of Metase, so he is quite looking forward to neutrino communication, he is looking forward to the hypothetical quantum entanglement communication proposed more than 20 years ago, theoretically will turn the whole universe into a world with zero delay, but the technical difficulty of it is verified by simple rule simulation, and it is found that the simulation speed is calculated in months, and he plans to make neutrino communication first.

"Mr. Advisor. Are you ready? Half a minute later, Cao Chuan received a response from Matasse, and then activated the neutrino receiver under the lunar base, which was also a hemispherical big guy, so that the neutrino beam propagating in a straight line could be aimed at the target.

The response from the other side disappeared, and he stared at the screen, guessing that Mesetta had made a move, activating a special monitoring program, and there was no information on the screen for the time being, even if it was a neutrino, the speed of crossing the universe was still the speed of light, and he would have to wait 30 seconds according to the current position of the emittion.

Although neutrinos exist in nature, such as those from the Sun and other galaxies tens of light-years away, these chaotic neutrinos do not have any practical meaning and are filtered by hardware or software means.

The screen lit up, a waveform appeared, high and low, and then he started the decoding device, such a gadget with no technical content, translated the waveform, and the words "HelloWorld" appeared on the screen.

"It worked!" Cao Chuan jumped up.

With the help of rule simulation, even a technology such as neutrino communication can be easily defeated.

He just wanted to do something, such as replying to a "received" message, when he suddenly remembered that the current neutrino communication is one-way, and the fleet managed by Bai Lian allows messages to be sent to the lunar base, and they are in the lunar base and have no way to respond.

"It's better to go the old way!" Anyway, the experiment was successful, Cao Chuan simply typed a line of text on the screen, which was sent out by the traditional way of radio waves, and after a minute, Metase's avatar appeared.

"Congratulations!" Metase replied that this was not only his honor, but also Cao Chuan's.

"Mr. Advisor, can I start the next phase of the research project, such as the research on smaller neutrino communication devices, and the popularization of neutrino communication base stations, etc.?"

Cao Chuan agreed to the plan, adding, "Don't forget another big application of neutrinos, deep geological scanning equipment." ”

"I won't forget." Metase hurriedly replied, remembering that he was negligent, although neutrino communication is a sweet spot for future communication in the eyes of many people, it will be an "artifact" in the eyes of geologists.

Neutrinos can easily penetrate a planet and reach the core of the planet at a depth of thousands of kilometers to understand the situation there, so its application in geology will include detecting the distribution of planetary resources at depths of several kilometers or more than ten kilometers, thus greatly reducing the work of the exploration department; There is also the exploration of the structure of the core part of the planet, so as to explore the secrets of the formation of the planet.

Although the deep geological scanning equipment has a bright prospect and will dig out all the treasures underground, there is nothing left, according to Cao Chuan's estimate, the biggest problem is that if you want to scan the entire planet once, you have to consume an unknown number of neutrinos, and the problem is focused on the cost.
