Abnormal crossing

Chapter 8: The New World (Please Read More)
The light screen that appeared in front of Gu Wei was like an open scroll, with a number of projections arranged from left to right:
The one on the far left is an appliance that looks like a rice cooker. To the right of the appliance is a slightly larger irregular oval composed of various aggregate symbols.

To the right of the ellipse is a smaller ball with two cores of different colors inside and several small dots around it.

There are many images on the right side of the ball, marked with symbols and words that Gu Wei cannot understand.

However, even though I don't understand it, it is not difficult to understand it in combination with the "standard framework" mentioned by Jin. These projections are the particle models that Jin knows.

"." Gu Wei's eyes quickly swept across the light curtain, and finally pointed at the fourth one, or the fourth group of models, and said, "It's about in this range. According to the electromagnetic information unit, it's called a quantum bit, and the model theory calls it fermions and bosons. The more representative particles among them are called quarks."

Well known.

Currently, all macroscopic matter that can be observed by the naked eye is composed of microscopic particles.

Microscopic particles, from large to small, are molecules, atoms, protons and neutrons (atomic nuclei), and finally elementary particles.

The elementary particles are mainly composed of four categories:
Quarks, leptons, gauge bosons and the Higgs particle.

These four major categories of particles are further divided into 61 types of microparticles.

Among them, the first two, quarks and leptons, are also called fermions - they constitute the earliest observable structure of matter.

There are six types of quarks, called the six flavors, namely up, down, top, bottom, strange, and charmed.

Each flavor of quark has three internal degrees of freedom, called colors, so there are 3X6=18 types of particles, and these 18 quarks have their own antiparticles, so there are a total of 36 types of quarks.

There are 12 types of leptons, including neutrinos and so on, so there are a total of 12+36=48 types of fermions.

As for gauge bosons and Higgs particles, they are collectively called bosons, which is the name of particles with integer spin.

Among them, gauge bosons transmit the basic interactions between particles, while the Higgs field in which the Higgs particle is located is responsible for producing rest mass. Therefore, the Higgs particle was separated out and became its own unique species, nicknamed the God particle.

Among the gauge bosons, there is only one boson that plays a role in electromagnetic interaction, and that is the photon.

As for the weakly interacting bosons, there are three, namely W+, W- and Z bosons.

The particles that transmit strong interactions are called gluons, and there are eight of them.

因此玻色子的总数一共有1+1+3+8=13种。

13+48=61, which constitute the 61 most basic particles in the world - or to be more precise, it is the particle physics model explored by the Earth's civilization circle before Gu Wei traveled through time.

Neutrons, protons, and mesons are all composed of two or more elementary particles, so they are called composite particles. They are usually larger than elementary particles and smaller than atoms.

The projection given by Jin is obviously far beyond the existing framework of the earth, but Gu Wei can still distinguish the first few items more or less - the first is macroscopic matter, then molecules and atoms, the fourth is fermions and bosons, etc., and composite particles seem to be classified into the third tier.

"I just realized the framework of 'Shi Zi'." Looking at the projection model that Gu Wei pointed to, Jin waved his hand again, and the light screen disappeared in an instant: "Then what about energy technology? Have you made any breakthroughs in cold fusion or controlled nuclear fusion?"

Gu Wei shook his head again: "No."

"That's strange," Jin crossed her arms over her chest and frowned slightly, "Then how did you get here?"

According to Gu Wei's introduction, the Earth is relatively primitive in terms of both physical framework and energy development. Even in the judgment framework of Type II civilization, it belongs to a lower level type. Theoretically, it is impossible to have technology related to space teleportation - because even the entry-level ordinary macroscopic object teleportation is the fifth particle framework, which is the related category of the next level of the so-called quark.

"Me?" Hearing Jin's question, Gu Wei couldn't help but smile bitterly. After thinking it over, he decided to tell the two foreigners the details: "I come from a country called Huaxia on Earth. A few days ago..."

Then Gu Wei recounted the common frequency signal, the mysterious pit, and his experiences before and after falling into the pit.

Although the Dark Forest Law is deeply rooted in people's minds on Earth, it still depends on the specific situation. At least Gu Wei doesn't think that revealing this information will cause any harm to the Earth.

As I said, exchanging information is the best solution right now.

Jin Jingjing listened to Gu Wei's introduction and frowned even more: "So you don't know what happened exactly?"

"That's right," Gu Wei sighed, and spread his hands helplessly towards Jin: "When I fell into the pit, I thought I would be killed in a minute. The only difference was who I could see in the resurrection match. I didn't expect to see you when I opened my eyes - I don't know the reason, I don't know what happened, and I don't even know where I am now."

"world."

Gu Wei emphasized the word "world" very much. He was expressing his thoughts in this way:
You two foreigners have been talking for so long, isn't it time to give him some information?

After all, he didn't know anything except the name of the planet Kedas. He was just like Kennedy picking dandruff, totally confused.
Jin exchanged glances with Milo beside him, and after a brief silence, he tilted his head slightly: "Yes, after all, we agreed to exchange information. Now it seems a bit like a one-sided inquiry. No problem, what do you want to know?"

Gu Wei pursed his lips, took a deep breath, and stared at Jin steadily: "First of all, I want to know your origins - I mean everything other than the so-called captain and mechanic, as well as information about the entire civilization circle including you and that so-called Kedas planet. Even a simple overview will do."

When Jin and Milo first met, they briefly introduced themselves. The word "spaceship" alone was enough to trigger Gu Wei's endless reverie. But if he wanted to verify the accuracy of those reverie, the words "captain" and "mechanic" were obviously far from enough.

Gu Wei must understand the intelligence of the civilized circle in order to make the most accurate judgment of his situation.

"It's a very reasonable request, and it's also very simple." After Gu Wei finished speaking, Jin responded readily: "But since we want to discuss news about the civilization circle, we must re-match some of our concepts."

Gu Wei was slightly startled, but soon realized something: "Is it the physical definition you mentioned before? Something like Sasag?"

Jin nodded and explained, "That's right. Language is a kind of coded product that life has customized. Cryptography is actually theoretical mathematics in essence. As long as we use the rule system to decipher it, we can complete the analysis."

"For example, our earlier and current communication actually involves a background program that is deducing and translating semantics in real time - it's just that the window of 'real time' is extremely short, so you can't feel it."

"But on the other hand, when it comes to the definition level, especially the physical definition, some content needs to be matched first."

"But don't worry, there isn't much that needs to be matched. You just need to repeat the most basic units of time and length on Earth. It doesn't matter if they are a little vague - I mean the basic units under the macroscopic state."

"Time and length." Gu Wei thought for a moment and quickly said, "The basic unit of time on Earth is called a second. Its definition has been iterated many times. The most accurate one at present is the duration of 133 cycles of the corresponding electromagnetic radiation when the cesium 9192631770 atom transitions between two hyperfine energy levels in its ground state. It's roughly like a tick, and that's one second."

"The next higher unit is called minute, which is equal to 60 seconds. Then there are hour, day, week, month and year."

"The basic unit of length is called meter, which refers to the distance light travels in a vacuum in 1/299792458 second. Its superior unit is."

Although the major of astrophysics seems to be related to stars and the sun, in fact, it deals more with mathematical formulas. The parameters that need to be calculated and mastered often start from five or six digits, and values such as the speed of light are the basics of the basics.

Therefore, some numbers that seem confusing and difficult to understand to ordinary people are basically no different from reciting "Quiet Night Thoughts" to Gu Wei.

When he was doing his doctorate, he knew a guy who kept reciting the LRL vector derivation of Mercury's perihelion precession in his sleep - the kind that recites it backwards.
A few minutes later.

"It's done!"

Jin snapped her fingers briskly. For scientists like her, being able to come into contact with an exotic physical framework is actually a very happy thing:

"The physical definition of the Earth has been matched with the standard regulations of the universe. For example, one Earth year is only about one-third of a standard cosmic year. Another example is that one Sag is approximately equal to 25.7635 kilometers."

Gu Wei blinked subconsciously: "Is there such a big difference?"

"It's OK, it's reasonable overall," Jin waved her hand nonchalantly, indicating that Gu Wei was not surprised by anything. "The basic units of most civilizations are usually related to main sequence stars, and stars are very diverse, so it's normal that the basic units of some civilizations are very different from the standard regulations."

"For example, there is a small planet called Sarmada more than fifty star units away from us. It is extremely far away from the main sequence stars. Not only is it extremely cold, but a year there is equivalent to more than 600 years on your Earth. Its rotation period is also close to your days."

Gu Wei's voice rose slightly: "Huh? More than 600 years?"

"That's right," Jin shrugged at Gu Wei, thinking of something interesting: "Back then, there was a star writer named the Whitest Crow who boasted to readers that he would update 50,000 words a day. When the time came, he argued that the so-called day was Sarmada Day. Later, that guy ended up in a miserable way. When he was hung up and his legs were broken for not updating enough for the 153rd time, I donated some money."

Gu Wei: “?!”

"Okay, let's stop talking about these trivial things and get down to business," Jin casually mentioned a cosmic anecdote, and her expression quickly straightened up: "Let me start with the civilization circle. This angle should be easier for you to understand."

Gu Wei quickly sat up straight.

Then Jin drew a random circle in the air with her finger and said, "In fact, in the literal sense, the word civilization is a very complex and broad concept, and it is very subjective."

"For example, a thatched hut of two or three primitive people is a civilization, a primitive tribe of a few hundred people is a civilization, a city of a million people is still a civilization, and a country with billions of people is still a civilization. What's interesting is that a country with billions of people may be extremely powerful on the planet, but in the universe it becomes the original thatched hut."

"What's even more interesting is that, on a cosmic scale, if primitive people's huts are lucky enough, they can still repeat the evolution from huts to kingdoms."

Gu Wei nodded. This statement was not difficult to understand.

Looking at Gu Wei who seemed to be thinking about something, Jin paused and continued, "A long, long time ago, there was a "hut"-level civilization that walked out of their star system and began to explore this starry sky."

"They encountered other primitive people living in huts in the universe. Some of those primitive people were brutal, some were friendly, and some were neutral. After a series of disputes and integrations, a more advanced cosmic-level 'tribe' was born, followed by a big city, and then a country."

"History on the planets is repeating itself in the starry sky."

"Then there were hundreds of thousands of years of evolution, with countries splitting and uniting, and finally forming an integrated civilization circle that was extremely complex."

"This stage of civilization, or this era, has a general name, called."

"Star Sea."
