Xueba's Sea of ​​Stars

Chapter 157 Type 0.72 Civilization

In the next two days, under the leadership of Song Nanfeng, Wu Bin saw a lot of domestic cutting-edge technologies, especially the quantum communication, which made him particularly interested.

At noon, Song Nanfeng sat down and looked at Wu Bin and asked, "You seem to be more interested in optics?"

"Yes." Wu Bin nodded, "Because I think that if a breakthrough is made on the issue of the speed of light, it will be a major leap forward for the entire physics."

Song Nanfeng paused after hearing the chopsticks in his hand, looked at Wu Bin and said, "Hey, the goal is set far enough, do you want to be the godfather of physics?"

"Don't dare, dare not." Wu Bin shook his head, "It's just that I became very interested in studying light after knowing that the ether reference system conjectured by Michaelson after measuring the speed of light directly led to the birth of Einstein's theory of relativity."

"Well, keep thinking about it, you will be the next Nobel Prize." Song Nanfeng's words did not mean to be teasing at all. After all, academic things are not afraid that you don't understand, but that you don't dare to think about them.

For example, the reward mechanism of the Nobel Prize is particularly inclined to those who dare to think.

If modern known science is a tomato, then almost all scientists are studying how to make this tomato more delicious, but if someone suddenly stands up and announces to everyone at this time.

"Actually, you can eat eggs too!"

And tried to make a poached egg that was fried like charcoal.

Then don't think about it, the Nobel Prize will definitely be given to that charcoal-like poached egg, even if the competitor is someone who can fry tomatoes until they shine.

"Well, if the vehicle can travel faster than the speed of light, human beings will be able to open up a new situation. It's very interesting to think about it."

"You are really thinking about your universe... oh no, your sea of ​​stars, right?"

Wu Bin nodded earnestly after listening, and said: "To be honest, I have always felt that the technological competition between countries is too small. The stars and the sea should be the goal of human unity."

"Hahahaha, yes, yes, depth, depth." Song Nanfeng laughed a few times, and then said: "In 1964, the former Soviet astronomer Nikolai Semyonovich Kadash Husband has actually set a scale for the level of civilization technology, which are Type I, II, and Type III civilizations."

"Type I civilization is able to mobilize energy equivalent to the output power of the entire earth for communication. Now we can understand most of the events that happen on the earth within a day, and we can leave the earth and go to the moon for lightning visits. It counts as a Type 0.72 civilization.”

"Wow... so harsh." Wu Bin couldn't help complaining.

Ignoring Wu Bin's complaints, Song Nanfeng went on to say: "A type II civilization is one that can use the energy of the entire star to communicate outwards, that is, the sun. For example, the Dyson sphere is an idea to advance human civilization."

"In the end, there is a type III civilization, which can use the energy of the entire galaxy to send messages."

After finishing speaking, Song Nanfeng took a sip of soup and said: "From the perspective of civilization, the technological competition between countries is indeed very small. In fact, when I was young, I often thought about it, or I sometimes think about it now. What kind of situation will we face if aliens come to visit the earth."

"Anyway, it's hard for me to imagine that they will communicate with us friendly..."

At present, the earth-like [Centaurus terrestrial planet] discovered by humans is 4.37 light-years away from us. How far is this distance, that is, even if it takes a rocket to go there, it will take 16.5 years.

So if there is an alien civilization that humans have not discovered and came to the earth through interstellar voyages, then the technological power is beyond the imagination of humans.

That would be the same as when the most valiant cavalry unit in ancient times was surrounded by tanks. No matter how much you showed off your riding and marksmanship, it would be solved with one shot.

Absolute crushing!
"It's true that the more you learn, the less you know." Wu Bin was shocked after eating a piece of braised pork.

"That's why science is so interesting, isn't it?" Song Nanfeng said with a smile.

"Also~" Wu Bin grinned and continued to eat.

After contacting Wu Bin in the afternoon, Gu Ningshan came over and said that she wanted to use his "body" to catch some more cats.

"I won't let you help me in vain. Tonight I will give you a few books on special relativity, all of which I think are worth reading."

Wu Bin immediately chose to agree after listening. Both are things he likes, so why not do it!
After walking around the campus with Gu Ningshan all afternoon, the two of them were not just looking for cats. During the chat, Gu Ningshan learned interesting news about the competition from Wu Bin, and Wu Bin learned about the juvenile class he was most curious about from Gu Ningshan.

It turned out that in the early 80s, the concept of youth classes had already appeared, and it was very popular. At that time, almost all top schools tried to run their own youth classes.

However, due to the incident of some "prodigies" being expelled from school at that time, the media continued to demonize the youth class, saying that it was destructive. Later, these news were described in even more exaggerated ways by some newspapers.

What is it that can read but can't even tie shoelaces, what is the EQ is too low, it is easy to be eliminated by society, etc...

Ordinary people also expressed their condemnation after watching it, and joined the ranks of denouncing the juvenile class.

This has led to the suspension of juvenile classes in many universities. Of course, poor management and failure to find teaching rules are also factors.

Until now, only the University of Science and Technology and Daxing Jiaotong University are left in the juvenile class, and they have all changed from classes to departments, which means that they are completely on the right track and have also cultivated a large number of talents.

Professor Song Nanfeng also said yesterday, "Since there are precocious people in the world, there should be corresponding education mechanisms, otherwise it would be a great waste of talents."

As for the content of the class, there is no difference between the junior class and other departments. Freshmen choose the majors they are interested in, but the competition in the class is probably stronger than other departments, after all, there are so many little monsters.

Through the summary of Gu Ningshan's narration, Wu Bin has almost been able to imagine the scene of the youth class. A 14-year-old boy who newly joined the class will soon be able to integrate into the group under the warm welcome of several 15- and 6-year-old brothers and sisters. , and excitedly discussed with everyone, from Dyson balls to chess, minesweeping algorithms, to electromagnetic railguns, etc., what a pleasure!

"Huh~ Today I really saw several cats that I haven't seen before." Gu Ningshan touched an orange cat at Wu Bin's feet, and looked at Wu Bin with eyes full of envy. This guy's attraction to cats is almost too fast Catch up with gravity.

"Meow~" After teasing the orange cat for a while, Gu Ningshan stood up and said to Wu Bin after confirming that there was nothing unusual about its body.

"Okay, you go to Dongyuan cafeteria and wait for me. I'll go back to the dormitory and bring you the books."
