Neutrino Detector

After destroying the Kun-Tai Civilization, humanity did not rush to leave Aldebaran. Instead, they returned to the orbits of the two Rocky Planet and resumed resource extraction, spaceship construction, and Technology Tree advancement.

Encountering the Kun-Tai Civilization taught humanity a valuable lesson: while the journey here was dangerous, the road itself was equally perilous. Rather than rushing off on a voyage, it was better to first calmly assimilate the Kun-Tai Civilization's technology and then break through to the Level 2 Civilization stage.

As for the battle of the gods broadcast by the Milky Way Galaxy Axis Alliance, well, we can only hope for good luck.

After learning from the Kun-Tai Civilization Database about the speed at which the Quell Civilization summoned the Silver Heart Alliance, humanity now knows that those advanced civilizations are in this star system, and at an alarmingly high speed.

Faced with such a civilization, whether you travel an extra 100 light-years or 200 light-years, it doesn't really matter.

Of course, you still have to run, but it's best to do so when you're strong enough. Otherwise, if you encounter another civilization next time, you'll have to fight another war with an uncertain future.

Time passed slowly amidst development and construction.

Fifty years have passed in the blink of an eye.

However, this fifty-year period is similar to the 20th-century slogan of achieving controlled nuclear fusion. Fifty years have passed, and although many technological breakthroughs have been made in Heavy Nuclear Fusion, it has still not become a reality.

Scientists say it will take another thirty years.

While Heavy Nuclear Fusion has not been achieved, another technology has made a theoretical breakthrough, and the first experimental device has been built.

Today, Yue Yuan arrived at the Engineering Department headquarters to participate in this experiment. When he arrived, the site was already filled with scientists and researchers from all walks of life.

As Yue Yuan and his assistant entered the gate, they headed towards the scientist in charge of the project. "Where should the detection target be placed?"

The scientist leading this project was not a familiar face, but a young man who had risen to prominence through his own talent—a physicist, communications expert, and project leader in the field of detection. His name was Dao Heiqi, and it's rare to find someone with the surname Dao.

This Dao Heiqi is also humanity's Chief Scientist for the past fifty years.

To prevent outdated thinking and incompetent officials from holding positions of power, the system stipulates that the position of Chief Scientist is selected once every fifty years.

Last year it was Yi Kai, and this year it's Dao Heiqi.

Dao Heiqi was very pleased to have achieved results during his term. Turning around and seeing Yue Yuan arrive, he immediately greeted him with a smile and then replied, "Commander Yue, the target is on the far side of Aldebaran A, and our experimental probe is located here."

Dao Heiqi turned around, raised his hand and pressed the remote control in his hand, drawing a small circle on the screen displaying the star map.

Yue Yuan looked up and found that the probe's location was exactly two planets away from its target. One was Aldebaran A, an Orange Giant Star, and the other was Giant Gaseous Planet.

With two planets separating the detector from the target, this experimental method is clearly unusual. And precisely because it's unusual, anyone with even a basic understanding of physics knows that this must be an experiment involving Neutrino Detection.

It's 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 to communicate.

Neutrino Communication was something humanity already possessed, thanks to the technology provided by the Moke Star People. However, back then, humanity only knew how to build it, not the underlying principles.

Now that the Neutrino Detection experiments have been completed, there is no doubt that the so-called theoretical breakthroughs that humanity has made in the past fifty years are related to neutrinos.

The device at the Engineering Department headquarters is not the probe itself, but rather its control unit. The probe itself is located where Dao Heiqi circled on the screen earlier, aboard a Probe Spaceship.

The targets of the probe were a Mountain-Class and several Callisto-Class Warships.

After Dao Heiqi's explanation, Yue Yuan understood the general outline of the experiment. He then asked several questions about the probe, such as whether the preparations were adequate, his confidence level, and when it would begin.

As a leading scientist, Dao Heiqi naturally had a knack for answering these questions.

However, after hearing that there was still some time before the experiment, Yue Yuan became curious about its principles. He was very curious about how Neutrino Detection was achieved.

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, which requires the target to be reflected back in order to detect it.

Having some doubts, Yue Yuan asked the question.

Faced with Yue Yuan's question, Dao Heiqi seemed to have no need to think before speaking, "Well, this is actually a detection method based on microscopic quantum effects. Neutrinos are also a type of microscopic particle, and microscopic particles all have quantum effects."

"Yes, just as we call photons 'light quanta,' photons themselves possess quantum effects, as do electrons and neutrinos."

Hearing Dao Heiqi's words, Yue Yuan nodded secretly.

He knew that the microscopic particles Dao Heiqi was referring to did not refer to all microscopic particles, but rather to indivisible microscopic particles.

A quantum is a concept; it refers to a physical quantity that is quantized if it has a smallest indivisible basic unit, and this smallest unit is called a quantum. It does not mean that a quantum actually exists like a photon or an electron.

Therefore, quantum effects naturally refer to the macroscopic effects manifested in various microscopic particles, or the overall quantum phenomena exhibited by a macroscopic system composed of a large number of microscopic particles.

Yue Yuan's scientific literacy was not bad, so he understood the general idea after Dao Heiqi said that.

Therefore, Yue Yuan understood that Dao Heiqi had not gotten to the point, so he began to listen attentively.

Sure enough, the next moment, Dao Heiqi continued, "The theoretical basis is the Parity Nonconservation Law. Twenty years ago, we studied this problem based on the Yang-Mills Theory and later discovered that Electron Neutrino, Muon Neutrino and Tau Neutrino exhibit a magical quantum effect under a certain Weak Force."

"This amazing quantum effect allows us to obtain pairs of entangled neutrinos using a certain device, much like obtaining light quanta. We have discovered that these neutrinos with amazing quantum effects change their spin direction to varying degrees when passing through different substances."

"Therefore, we can emit neutrinos with Quantum Entanglement properties, and then, by observing the instantaneous Quantum Collapse effect of the corresponding entangled particles of the Electron Neutrino in the detector in the Weak Force, we can roughly understand what our emitted neutrino beam passed through."

From Quantum Electrodynamics, this process involves something quite interesting happening as neutrinos propagate through space: they transform from one flavor to another, somewhat similar to the Quark Flavor Change. This process is called Neutrino Oscillation.
