Chapter 531 Neutrino Radar

After Liu Xiu chatted with Kane for a while, Kane left, and Liu Xiu waited for Lina to control the repair robot. After repairing the hatch of Descloud, Liu Xiu also drove the newly acquired Descloud and the Flying Bird back to the Wandering Blue Planet.

Of course, after flying back to the Blue Planet, Disclaude naturally faced the fate of being dismantled and studied.

The most important research direction is naturally to study what kind of radar Disklaude used.

Fortunately, Descloud is a battleship without any intelligent consciousness, so it will not make any noise no matter how it is dismantled.

Of course, it would be even better if it had intelligence, just like Lina on the Asuka battleship. There is no need to disassemble it, all the information can be provided directly, which saves trouble. After all, cracking is not as convenient as obtaining information!

Although this lost battleship without self-awareness uses high-tech radar technology, it has no self-repair function because it has no intelligence.

As the Descloud was dismantled, the scientists of the Wandering Blue Star finally understood, after some research, why the radar detection range of Descloud's battleship was so large. It turned out that the Descloud battleship used neutrinos as a medium to have such a large detection distance, and the enemy's electromagnetic radar would not respond.

Because ordinary radar uses electromagnetic waves as a means of detection, just like bat radar uses ultrasonic waves as a means of detection.

Neutrino radar obviously uses neutrinos as a means of detection.

Of course, wandering blue stars with neutrinos were discovered in the early twentieth century. Although they were discovered, neutrinos are relatively difficult to use.

As for what neutrinos are, in fact, neutrinos are a type of lepton, one of the most basic particles that make up nature.

Neutrinos are small, have no charge, and can pass freely through blue stars. They only participate in weak interactions, which makes them appear to have no mass, but in fact they are not.

Neutrinos have mass, but because they interact so little with matter, they are difficult to calculate.

If this problem is solved, we can then conduct a more detailed study of the mass of the entire universe, which will greatly assist in cosmological calculations.

Calculating the mass of a neutrino is a difficult task. Even by the standards of elementary particles, it is minuscule, having no electrical charge and a very small mass, so its penetrating power is enormous, almost infinite.

Imagine a layer of lead a few hundred light years thick - to neutrinos, it would be like air.

Of course, it is precisely because of this that they travel freely through the human body every second without leaving any consequences, or even if there are consequences, they will not be noticed by humans at all.
In the history of scientific research on the blue planet, the first person to propose the existence of neutrinos was theoretical physicist Wolfgang Pauli, who was the discoverer of the spin of elementary particles in the early 1930s.

He discovered that the law of conservation of energy could not be realized in the decay of the neutron without other particles, and it was subsequently called the "little neutron."

Of course, this person only proposed a hypothesis. More than 20 years later, until 1956, scientists proved the existence of this particle through experiments.

But where do these elusive particles come from? This is naturally the same place where light in the universe comes from. Yes, it is naturally the stars in the universe. All stars in the universe have a huge thermonuclear reactor, which in turn produces countless neutrinos.

Exactly how many of these is unknown, since the blue star does not receive all of the neutrinos produced by the Sun.

Because scientists think that on the way to the blue star, some neutrinos simply transform into other types of neutrinos.

Scientists have detected all the types of neutrinos emitted by the sun and found that electron neutrinos account for only one-third of them. This confirms the neutrino transformation.

Of course, since neutrinos have mass, their speed is naturally not faster than the speed of light. After all, once neutrinos are faster than the speed of light, all previous theories will be overturned. Light is indeed the speed limit in the universe.

Of course, in the process of studying neutrinos, some people have proposed that the speed of neutrinos is faster than the speed of light, and have also proved it through experiments. However, the final result proves that photons are the fastest, and neutrinos are slower than the speed of light.

Because a cable came off while conducting research at the collider, which affected the results. After the fault was discovered, repeated research showed that the speed of neutrinos was significantly lower. Therefore, not as fast as the speed of light.

Of course, due to the unparalleled penetrating power of neutrinos, scientists have also made some speculations about the application of neutrino technology.

For example, in the diagnosis of nuclear reaction processes, the most obvious application of neutrinos is in nuclear reactors. Of course, this field is actively being researched and developed, and various sensors are being studied based on these neutrinos, hoping to be able to monitor the power of nuclear power plant reactors in real time and understand the composite composition of their fuel.

In addition to neutrino detection in nuclear reactors, neutrino astronomy is also a good direction for development. Here, these particles are not really used, but simply studied. In this scientific field, the neutrinos studied do not come from the sun, but from other, more distant stars.

Through these studies, it is possible to discover the properties of even very distant objects. Since any star, in essence, has a thermonuclear reactor, it emits a large number of neutrinos. In the course of their studies, scientists have discovered that as a star ages, the number of particles it forms gradually decreases. In its "death moments", a star loses up to 90 percent of its neutrinos, which is why it begins to cool.

In addition to astronomical research and nuclear reactor monitoring, neutrinos are also used in geological research. Neutrinos are not only produced in stars, but also in the radioactive decay of certain chemical elements, even on the blue planet. This allows us to study the geological composition of the blue planet in more detail.

Of course, all of the above are just ideas about the use of neutrinos so far, and have not been put into practice, because neutrino sensors are really difficult to manufacture.

The characteristics of neutrinos make them difficult to capture, because neutrinos travel at sub-light speed, only 6 millionths lower than the speed of light.

However, it does not have the photoelectric effect like photons and cannot be easily captured.

However, after Descloud was captured, the sensors on it that could capture neutrinos were gradually studied and understood.

Of course, after the research, we have to sigh that prehistoric civilization is indeed very good at scientific research. Although the energy consumption of the neutrino detectors it manufactured is a bit high, this is nothing for a spacecraft that uses spiritual energy.

Of course, the reason why the neutrino detectors made by prehistoric civilizations consume huge amounts of energy is mainly related to the way they capture neutrinos.
