Road to science and technology

"The weak interaction force, one of the four fundamental forces?" He Xi confirmed again.

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

The force range of the weak interaction force is very short, almost zero. As soon as the particles participating in the weak interaction move away from each other, the force quickly disappears.

The weak force does not bind any particles in a more complex system at all. It only exists at the moment when some particles decay and are captured. As soon as the particles separate from each other, the weak force disappears immediately.

"How much do you angels know about the weak interaction force?" Yue Yuanzhou did not rush to answer He Xi, but asked this question first.

He Xi thought about it for a moment, put his hands on his knees and sighed: "Not much. After obtaining the method to enter the dark plane tens of thousands of years ago, we angels have been committed to the research and application in this area.

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

Hexi continued to talk about her understanding of weak forces and other civilizations.

Like the Kamigawa civilization, they all believe that the four fundamental forces and some other basic theories are just the keys to unlocking the door to dark matter and dark energy.

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

Indeed, the threshold for detecting dark energy and dark matter is extremely high, let alone mastering their application methods. In order to master dark matter and dark energy, civilizations such as Lieyang, Kamigawa, and Deno must have made great efforts in the past, so they all regard dark matter and dark energy, which have extremely high thresholds, as signs of advanced civilizations.

Yue Yuanzhou leaned on his chair and listened to He Xi who seemed to be talking about the history of the development of science and technology of angel civilization. For a moment, he didn't know whether to complain or not.

In fact, if there is no dark plane, they are committed to studying dark energy and dark matter. It is really possible for their civilization to become a civilization that specializes 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 certain super civilization after mastering the first two.

After He Xi finished speaking, Yue Yuanzhou said: "Whether it is dark energy, dark matter or other branches of science, none of them are unimportant. Any civilization that studies one direction to an extremely deep level is unparalleled.

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 very simple may actually be considered difficult by them and have extremely high thresholds. "

Yue Yuanzhou thought for a moment, and it seemed that the life forms in the super-god universe, apart from the Kamigawa body, were the Triangular bodies, which were also carbon-based life forms, so he continued: "Well, it's like the Triangular bodies, their sensory organs, the way their thinking organs evolve, etc. They are all different from other people, so some behaviors may seem unreasonable to you, but they are natural to them.

In fact, triangles are okay, they are still carbon-based life. In other universes, there are all types of life, so when they come into contact with each other, it is easy for them to have ideological impact and even a technological explosion. "

He Xi nodded in agreement and said: "So we were all tricked by the Kamigawa civilization. They interfered with all life processes in the known universe through genetic technology, so that their final evolution direction was the Kamigawa body."

"That's not entirely true. At least from another perspective, this method also greatly unifies the thoughts among civilizations in the entire known universe. In this case, communication among cosmic civilizations is not as difficult as other life forms in the universe. Crossing species barriers and becoming irreconcilable, in this environment, peaceful coexistence among civilizations in the universe can be easily achieved. Misfortune lies where blessings depend, and blessing lies where misfortune lies. Each has its own advantages and disadvantages."

At this time, He Xi 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 the blazing sun!"

Yue Yuanzhou did not disappoint her either. His voice rang in the hall: "We have concluded from the detection results that Lieyang civilization was hit by a method based on weak interaction force.

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

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

Hexi glanced at Karl in surprise, wondering why this guy's mouth suddenly became so poisonous, but she was not angry because Karl didn't understand the sacred atom at all. In her opinion, Karl's words were completely espionage, and the purpose was to make people She said something about the divine atom.

So she pretended not to hear what Karl said, turned to Yue Yuanzhou and said, "Of course we know this."

He Xi knew that parity non-conservation was actually learned from Yue Yuanzhou's "Twilight of the Gods", but she did not say so, because Karl was here, and saying so would not disgrace the angelic civilization.

Yue Yuanzhou didn't know He Xi's psychological activities, nor did he care when she knew it. He only needed to confirm that He Xi knew about it, 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 from 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. Protons and neutrons are complex nuclear particles. The proton is composed of two up quarks and one down quark, and the neutron is composed of two up quarks and one down quark. It is composed of one up quark and two down quarks."

"In order for one element to change into another element or its isotope, its mass number must be increased or decreased. Either the number of protons is increased or decreased, or the number of neutrons is increased or decreased."

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

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 change of '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. This is positive beta decay. Positive beta decay releases a positron, that is Electron antimatter.

And many times, the instability of the atomic structure is not because there are too many electrons outside the nucleus, but because there are too few 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 the 'flavor' change of quarks. For example, if a neutron's down quark becomes an up quark through the weak interaction force, the neutron will become a proton. This process will release Electrons are beta particles, as well as anti-electrons and neutrinos.”
