The road to technology

Chapter 572 Quark Flavor Change
"Weak interaction force, one of the four fundamental forces?" Hexi confirmed again.

Where is the foundation of the angelic civilization, it is impossible for her not to know the four basic forces.But because of this, she immediately felt that it was impossible, and said: "The weak interaction force is the shortest force range among the four basic forces, and it only appears in some decay moments. How can it be used as a weapon?"

The weak interaction force has a very short range of force, almost zero, and the force disappears as soon as the particles participating in the weak interaction leave each other.

The weak force does not bind any particle in a more complex system at all, it only exists at the moment when some particles decay and capture, and the weak force disappears as soon as the particles leave.

"How much do you angels know about the weak interaction force?" Yue Yuanzhou didn't rush to answer He Xi, but asked a rhetorical question first.

He Xi pondered for a while, then put his hands on his knees and sighed: "Not much, after tens of thousands of years ago we obtained the method to enter the dark plane, we angels have been committed to the research and application of this aspect.

Even though the dark plane was destroyed later, we still focus on dark matter and dark energy as the main research directions.Mastering dark energy has always been a hallmark of an advanced civilization, so you know, we, including the Kamigawa civilization and some other civilizations, are not committed to studying these fundamental forces in depth. "

Hexi continued to talk about her knowledge of the weak and other civilizations.

They, like the Kamigawa civilization, believe that the four basic forces and some other basic theories are just the keys to open the door to dark matter and dark energy.

In their impression, there is no need to study such low-level things after mastering more advanced dark energy.

Indeed, the threshold for detecting dark energy and dark matter is extremely high, let alone mastering its application methods.In order to master dark matter and dark energy, civilizations including Lieyang, Kamigawa, and Deno must have made great efforts in the past, so they all regard dark matter and dark energy with a very high threshold as a sign of advanced civilization.

Yue Yuanzhou leaned on the chair and listened to Hexi who seemed to be talking about the history of technological development of angelic civilization, and didn't know whether to complain or not for a while.

In fact, if there is no dark plane, they are devoted to the study of dark energy and dark matter, and the civilization may really become a civilization specialized in this field.

After all, dark matter and dark energy exist objectively, but the dark plane does not. The dark plane is a product created by a super civilization after mastering the former two.

Seeing that Hexi had finished speaking, Yue Yuanzhou said: "Whether it is dark energy, dark matter or other scientific branches, none of them is unimportant. Any civilization that studies a direction to an extremely deep level is an unparalleled existence.

You should know that the innate conditions of different races are different. Some technologies that we think are difficult are entry-level for them, while technologies that we think are easy may be considered difficult by them. The threshold is extremely high. "

Yue Yuanzhou thought about it for a while, and it seems that the life form of the super god universe is the triangular body, which is also a carbon-based life, besides the Shenhe body, so he continued: "Well, it's like a triangular body, their sensory organs, thinking organs, and so on. They are all different from people, so some behaviors that seem unreasonable to you are natural to them.

In fact, the triangular body is okay, it is still a carbon-based life, and in other universes, there are all types of life, so when they come into contact with each other, it is easy to have a thought shock or even a technological explosion. "

He Xi nodded and agreed: "So we have all been cheated by the Shenhe civilization. They have interfered with all life processes in the known universe through genetic technology, so that their final evolution direction is the Shenhe body."

"It's not all right, at least from another perspective, this method has greatly unified the thoughts among civilizations in the entire known universe. In this case, the communication of civilizations in the universe is not as difficult as other life in the universe. Crossing the barriers of species and becoming irreconcilable, it is easy to achieve peaceful coexistence among cosmic civilizations in this environment. Disasters are blessings, and blessings are disasters. Each has its own advantages and disadvantages."

At this time, Hexi stood up and looked at the command hall, but her eyes seemed to look beyond the wall into the depths of the universe: "Let's talk about Lieyang!"

Yue Yuanzhou didn't disappoint her either, his voice sounded in the hall: "We have concluded through the detection results that the Lieyang civilization has been hit by a weak interaction force.

You should know that the weak force is the only interaction that can change the flavor of quarks, and it is also the only interaction that can cause parity to be violated, so it is also the only interaction that violates CP symmetry. "

At this time, Karl suddenly interjected: "You think highly of angels too. As far as I know, the research of angel civilization on microscopic particles has always stopped at the atomic level, or they are called holy atoms instead of holy quarks and holy strings."

Hexi glanced at Karl unexpectedly, why did this guy's mouth suddenly become poisonous, but she was not angry, because Karl didn't understand the sacred atom at all, and what Karl said was completely spying to her, the purpose was to make She said about the sacred atom.

So she pretended not to hear Carl's words, turned around and said to Yue Yuanzhou, "Of course we know that."

Hexi knew that parity was not conserved from Yue Yuanzhou's "Twilight of the Gods", but she didn't say that, because Karl was here. Wouldn't it be embarrassing for Angelic Civilization to say that.

Yue Yuanzhou didn't know about Hexi's mental activities, and he didn't care when she knew about it.He just needs to confirm that Hexi knows, so he continued: "The situation of Lieyang shows that the basic particles that make up them have undergone extremely rare changes, some have become corresponding isotopes, and some have even changed the composition of matter, such as changing from carbon to carbon. Elements become nitrogen and even other elements."

"Through the evidence collected on site and the corresponding theoretical reasoning, we can confirm that the cause of these phenomena is quark flavor change. Both protons and neutrons are complex nuclear particles, in which protons are composed of two up quarks and one down quark, and neutrons are composed of two up quarks and one down quark. It consists of an up quark and two down quarks."

"And to make one element change into another element or its isotope, you must increase or decrease its mass number. Either increase or decrease the number of protons, or increase or decrease the number of neutrons."

Yue Yuanzhou stood up and looked at the illusory projection in front of his eyes with his hands behind his back. Inside was the re-projected scene of the scorching sun.

He continued: "Theoretically, we can directly change the "flavor" of the up quark and turn it into a down quark. The force that controls this "flavor" is the weak interaction force."

"Through the weak interaction, an up quark in the proton changes "flavor" into a down quark, then the proton becomes a neutron and releases a positron, which is positive beta decay. Positive beta decay is the release of a positron, that is Electron antimatter.

In many cases, the instability of the atomic structure is not because there are too many electrons outside the nucleus, but because there are fewer electrons outside the nucleus.At this time, it is necessary to increase the number of protons to stabilize the atomic structure. "

"Similarly, increasing the number of protons can still be done through quark 'flavor' change. For example, let a neutron down quark become an up quark through the weak interaction force, so that the neutron becomes a proton. This process will release Electrons are beta particles, and anti-electrons and neutrinos."
