Humanity is missing, luckily I have billions of clones.

Chapter 223 The powerful bricks fly away
At this moment, Li Qingsong still didn't know the specific path of proton decay.

It could decay into a positron and a pion. If so, the pion would then decay into two photons, and the positron would annihilate with surrounding electrons, also producing additional photons.

It is also possible that it decays into a muon and a kaon through another decay path. The kaon will also decay into a pion, and then into a photon.

Or it could decay into neutrinos and kaons.

The different decay paths speculated by Li Qingsong have one thing in common, that is, the final products cannot be separated from photons.

Therefore, following a detection mechanism that is almost identical to that for detecting neutrinos, as long as the detector's photomultiplier tube can capture the photons produced by proton decay, or detect the Cherenkov radiation produced by the superluminal motion of the intermediate product in water, it can be determined that proton decay has been detected, and through the various phenomena of this process, the specific path and detailed data of proton decay can be explored.

Of course, since it is used to detect proton decay, neutrinos also become interference at this moment.

Neutrinos have extremely strong penetrating power, and even if Li Qingsong built a detector tens of thousands of meters underground on a dwarf planet, it would be impossible to eliminate them.

Fortunately, the microscopic particles and phenomena produced by neutrino collisions are somewhat different from those produced by proton decay.

Li Qingsong can then formulate corresponding algorithms and judgment procedures, and by controlling the clone himself to make judgments, he can eliminate neutrino collision events.

At this moment, powered by a dedicated nuclear fusion power station, this huge underground test device began to operate.

The spherical water storage tank, which is as high as 1.2 million tons, has a diameter of more than 600 meters.

The massive sphere, with a diameter of over 600 meters, truly towered like a mountain. If the gravity of this dwarf planet weren't sufficiently low, Li Qingsong would have been greatly troubled by the tank material alone.

But even on a dwarf planet, in order to bind the water, Li Qingsong had to adopt a special tank structure and combine it with the support of the dwarf planet's own rocks to keep it stable and prevent deformation.

In this sphere as majestic as a mountain, Li Qingsong installed billions of photomultiplier tubes to maximize the sensitivity and not miss any photons.

The data generated by these billions of photomultiplier tubes are eventually gathered in a supercomputer built specifically for this purpose to analyze and identify the data.

Combined with various other facilities, Li Qingsong excavated more than ten billion tons of earth just for this proton decay detector, filling up a canyon on the dwarf planet.

In addition to the huge cost of initial construction, Li Qingsong had to place about 10,000 clones here for later maintenance alone. At the same time, he drew on the brainpower of an additional 100,000 clones, so that they could do nothing but think about things related to this detector.

But even so, this is just the beginning.

How can one proton decay detector be enough?

Don't forget, 10^36 years is only the lower limit of the proton's lifespan. Li Qingsong doesn't know its true lifespan at the moment.

What if its lifespan is 10^46 years? In this case, from a probabilistic point of view, the probability of this detector detecting a proton decay event in one year is only one in hundreds of millions.

Even if its lifetime wasn't that long, Li Qingsong still had to consider more. Even if Li Qingsong had improved the accuracy as much as possible, it would still be impossible to accurately capture every proton decay event. It's very likely that even if a proton decay occurred, it would be missed by the detector or misidentified as a neutrino event.

Even if Li Qingsong can accurately capture every proton decay event, it is not possible to thoroughly study the process of proton decay with just one observation.

It would take hundreds of thousands, or even millions or tens of millions of repeated observations to truly clarify its entire pattern and process, and ultimately turn it into a theory and add it to one's own grand unified formula framework.

In this case, how can one detector be enough?
In fact, Li Qingsong’s plan for proton decay detection is not one, not ten, but 1000 detectors!
If the accuracy is not enough and the probability is too low, then make up for it with quantity!

For an ordinary electroweak civilization, an entire civilization would only need to build three or four of these super-large scientific devices, and would not be able to support more.

Even if the industrial infrastructure capacity can support it, the talent pool cannot.

This thing can't just be built and put there and it will run automatically. It still needs the input of a large number of top scientists.

One detector requires at least 10,000 top scientists!

Only a few are built, and then every possible way is tried, little by little, to accumulate, little by little, relying on the method of water dripping through a stone, and slowly iterating and optimizing to improve the detection accuracy as much as possible in an attempt to detect the complete proton decay process.

But at this moment, Li Qingsong didn't have the time!

Even if Li Qingsong had the time, he would not do that.

Wouldn't it be stupid to not use our super-strong industrial strength and instead follow the path of an ordinary electro-weak civilization?
It's all about brute force, it's all about using all the force, this is Li Qingsong's strength.

So, under Li Qingsong's control, tens of thousands of small scientific research vessels began to fly towards the almost countless larger asteroids and dwarf planets in the Pegasus V432 star system, comprehensively examining their geological structure, elemental composition and other data, and selecting suitable construction sites.

It cannot be too large, otherwise its own gravity will be too high, causing the pure water tank to deform.

It cannot be too small, otherwise the rock layer will not be thick enough to provide adequate protection for the detector.

It cannot have too many heavy elements, otherwise its own background radiation will be too high, seriously interfering with the performance of the detector.

It cannot be too close to the star, because V432 Pegasi is a real source of strong neutrino radiation.

It can't even get too close to gas giants, because gas giants also emit a lot of neutrinos.

After some selection, Li Qingsong quickly selected 1000 target planets. Then, heavy transport ships were dispatched, loaded with various materials produced in the industrial base, various engineering machinery, and a large number of clones and humanoid general-purpose robots, and landed on these planets. With the cooperation of Shengong AI, a new round of large-scale construction began.

At this moment, without any spacecraft manufacturing or preparation for the fleet's voyage, the huge industrial system that Li Qingsong had prepared in the early stage entered full operation.
