Chapter 216 Neutrino Detector

After destroying the Kuntai civilization, humans did not rush to leave Aldebaran. Instead, they returned to the orbit of the two rocky planets and started resource mining, spacecraft construction, and climbing the technology tree again.

After encountering the Kuntai civilization, humans also understood a truth, that is, although it is dangerous here, it is also dangerous on the road. Instead of rushing to sail on the road, it is better to calm down and digest the technology of the Kuntai civilization first, and then break through to the second-level civilization level.

As for the fight between gods in the broadcast of the Galactic Axis Alliance, we can only pray for good luck.

After learning from the Kuntai civilization database how fast the Quill civilization attracted the Galactic Heart Alliance, humans already knew that those advanced civilizations were in this star field, and the speed was terrifyingly high.

In front of such a civilization, running one hundred light years or two hundred light years more is actually the same.

Of course, you still have to run, but it is best to run when you are strong after all, otherwise the next time you encounter another civilization, you will have to fight another war with an uncertain future.

Time slowly passed in development and construction.

Fifty years passed in a flash.

However, this fifty years is just like the slogan of achieving controlled nuclear fusion that humans shouted in the 20th century. After fifty years, although many related technical breakthroughs have been made in heavy nuclear fusion, it has not become a reality.

Scientists say that it will take another thirty years.

Heavy nuclear fusion has not been achieved, but another technology has made a breakthrough in theory, and the first experimental equipment has been built.

Today, Yue Yuan, who arrived at the headquarters of the engineering department, came to participate in this experiment. When he arrived at the scene, it was already full of scientists and researchers from all walks of life.

Yue Yuan and his assistant just walked into the door and walked towards the lead scientist of the project: "Where is the detection target?"

The scientist who led this project was not an old acquaintance before, but a young man who was promoted to the new generation with his own talents. He was a physicist, communications expert, and the lead scientist of the detection field project. His name is Dao Heiqi, and it is rare to have the surname Dao.

This Dao Heiqi is also the chief scientist of mankind in the past fifty years.

In order to prevent outdated ideas from being idle, mankind has stipulated in the system that the position of chief scientist is selected once every fifty years.

The last term was Yi Kai, and this term is Dao Hei Qi.

Dao Hei Qi seemed very happy to be able to achieve results during his term. When he turned around and saw that it was Yue Yuan, he immediately greeted with a smile, and then replied: "Yue Shuai, the target is on the back of Aldebaran A, and the location of our experimental detector is here."

Dao Hei Qi turned around, raised his hand and pressed the remote control in his hand, and drew a small circle on the screen showing the star map.

Yue Yuan looked up and found that the location of the detector was exactly separated from the detection target by two planets. One was naturally Aldebaran A, which is an orange giant, and the other was a giant gas planet.

There are two planets between the detector and the detection target. Such an experimental method is obviously very special. Precisely because of its specialness, anyone who knows a little physics knowledge knows that this must be an experiment about neutrino detectors.

It is a detector, not neutrino communication.

The difference between the two is that the former uses neutrinos to detect and identify unknown targets, while the latter relies on two neutrino transmitting and receiving terminals for communication.

Neutrino communication was already available to humans before, and it was the technology given by the Mok people. However, humans only knew how to make it at that time, and did not know the principle.

Now that the neutrino detector experiment has come out, there is no doubt that the so-called theoretical breakthrough of mankind in the past fifty years is about neutrinos.

As for the detector at the headquarters of the engineering department, it is not the detector itself, but the control end of the detector. The detector itself is located where Dao Heiqi circled on the screen just now, and it is carried on a detection spacecraft.

The detection target is a Mountain-class and several Ganymede-class warships.

After Dao Heiqi's introduction, Yue Yuan also understood the general idea of ​​the whole experiment. Next, he asked a few more questions about the detection experiment, such as whether the preparations were in place, whether they were sure, and when to start.

As a leading scientist, Dao Heiqi naturally had answers to these questions.

However, when he heard that there was still some time before the experiment, Yue Yuan became curious about its principle. He was very curious about how neutrino detection was achieved.

Because according to common sense, neutrinos have very strong penetrating power, and even if they penetrate a star, they will not be reflected back.

The so-called conventional detector detection is obviously the same as radar, and it needs to be reflected back to detect the target.

Yue Yuan had doubts in his heart, so he asked this question.

Facing Yue Yuan's question, Dao Heiqi didn't seem to need to think, and said: "This is actually a detection method based on microscopic quantum effects. Neutrinos are also microscopic particles, and microscopic particles all have quantum effects.

Well, just like we call photons light quanta, photons themselves have quantum effects, and so do electrons and neutrinos."

Listening to Dao Heiqi's words, Yue Yuan nodded secretly.

He knew that the microscopic particles in Dao Heiqi's mouth did not refer to all microscopic particles, but to indivisible microscopic particles.

Quantum is a concept that means that if a physical quantity has the smallest indivisible basic unit, then the physical quantity is quantified, and its smallest unit is called a quantum. Instead of a real quantum like photons and electrons.

Therefore, quantum effects naturally refer to macroscopic effects manifested on various microscopic particles, or the overall quantum phenomenon presented by a macroscopic system composed of a large number of microscopic particles.

Yue Yuan's scientific literacy is not bad, so when Dao Heiqi said this, he got a general idea.

Precisely because of this, Yue Yuan understood that Dao Heiqi did not get to the point, so he then pricked up his ears and listened carefully.

Sure enough, the next moment, Dao Heiqi continued: "The theoretical basis is the law of non-conservation of parity. Twenty years ago, we studied this issue based on the Yang-Mills theory, and later discovered the electric neutrino. , muon neutrinos and tau neutrinos will produce a magical quantum effect in a certain weak force field.”

"This magical quantum effect allows us to obtain pairs of neutrinos with entangled properties by using certain equipment just like obtaining light quanta.

We found that these neutrinos with magical quantum effects will change their spin directions to varying degrees when passing through different materials."

"So, we can emit neutrinos with quantum entanglement properties, and then through the instantaneous quantum collapse effect on the corresponding entangled particles of the electron neutrinos in the detector in the weak force field, we can roughly understand , the neutrino beam we emitted passed through something.

If this process is described from the perspective of quantum electrodynamics, something very interesting will happen when neutrinos propagate in space. They will transform from one flavor to another, which is somewhat similar to the flavor of quarks. Change, this process is called neutrino oscillation. "
