For a blue giant star that is about to explode as a supernova, even under normal circumstances, it is difficult enough to get close enough to observe it.

Its material ejection is too violent, and its external radiation is also too violent. This makes it difficult for any detector to get close to it. Or even if it gets close, it won't be able to hold on for too long and will be destroyed.

However, compared to when a supernova explosion actually occurs, the radiation emitted by this blue giant star during normal times is nothing at all.

Once a supernova explosion occurs, at that moment, the brightness of a single star can even overwhelm the combined brightness of hundreds of billions of stars in the entire Milky Way. With such violent radiation, I am afraid that no matter what Han Yang does, All defense methods are completely useless.

In this case, how to conduct close and effective observations of the specific processes during supernova explosions and the formation of macroscopic black holes?

Han Yang concluded that this was simply impossible to do.

But does this mean that Han Yang cannot obtain relevant data at close range?
No.

Long before setting off from the Milky Way, Han Yang already had a complete set of plans.

This plan was used by Han Yang when human civilization was promoted to level five civilization and observed the neutron star.

That is, trading quantity for quality.

Even if a single detector can only conduct one microsecond or one nanosecond of observation and data collection when a supernova explodes, it is enough.

If one detector is not enough, use ten. If ten are not enough, use a hundred, a thousand, or even a hundred billion or a trillion!
As long as the number is large enough, enough observation time can always be accumulated and enough data can be collected!

But compared to the original observation of the neutron star, the engineering difficulty at this moment is undoubtedly much higher.

The key difficulty is that Han Yang must observe this star in multiple ways and in multiple dimensions, instead of just observing one point like he did at the beginning.

Neutrinos, gamma rays, infrared rays, gravitational waves, and even dark energy fluctuations, space curvature, and the inevitable space tearing, etc., are all observed.

Each observation need requires different observation equipment. These observation equipment, such as neutrino telescopes, require the construction of a thick shielding layer and at least hundreds of thousands of tons of pure water. The total mass of a detector can reach more than one million tons.

If a detector with a mass of more than one million tons can only observe for one microsecond, more than 100 million such detectors would be needed to accumulate one second of observation time. What a huge project is this?

This is just one type of neutrino observation. Coupled with the rest of the detection needs, the total project volume put even Han Yang under tremendous pressure.

"I'm afraid that even if there is no Silver Alliance in the Milky Way, any level 5 civilization can freely detect supernovae and the formation process of macroscopic black holes. It would be extremely difficult to obtain enough data to become a level 6 civilization. Unimaginable things are tasks that most level five civilizations simply cannot accomplish.”

Han Yang felt a little emotional in his heart: "I'm afraid that most fifth-level civilizations will choose to rely on long-term accumulation to complete promotion, rather than thinking about obtaining enough data through one observation."

Too much work? Then I will build fewer detectors. Once a macroscopic black hole is formed, I will only collect a little data. When a macroscopic black hole is formed next time, I will collect more data.

In this way, time is exchanged for the amount of work, relying on long-term accumulation, bit by bit to collect enough data and complete the promotion.

But this method is obviously not suitable for Han Yang. If that were the case, I'm afraid it wouldn't be possible without tens of thousands of years of accumulation. But Han Yang did not intend to stay in the Canis Major dwarf galaxy for too long.

In this case, we can only give full play to our engineering advantages again and trade the amount of work for time.

Therefore, when there were only about 500 years left before the supernova exploded and the macroscopic black hole was formed, Han Yang turned his swords into plowshares and let his horses go to Nanshan. He idled more than one million warships and devoted almost all his computing power to the construction of the project. .

Trillions, tens of trillions of robots and intelligent machines, as well as millions of transport ships, space carriers, ferry ships, and a total of tens of millions of large factories on the surface of the planet, all started busy at the same time at this moment .

Han Yang was firing on all cylinders and going all out.

Under this situation, the first batch of 50 gamma ray detectors were built.

These detectors all have thick protective layers, and they even have their own small quark fission-fusion dual reactors inside to provide energy and can support a protective shield with a certain power.

They were transported by a transport ship sent by Han Yang to a place three light years away from the star. They stopped in the endless vast void and aimed at the blue giant star.

After that, came the first neutrino telescopes.

These neutrino telescopes have the same protective power, but their individual masses are much larger, reaching about 50 tons.

Han Yang built 3 units and placed them light years away.

After that, a total of more than 10 billion detectors of various types were built and placed there.

They appear uniformly distributed overall. With this blue giant star as the center and a radius of 3 light years, it faintly surrounds the blue giant star.

After that came the second batch of detectors. This time, Han Yang placed them 2.9 light-years away from the blue giant stars, and the total number was also about 10 billion.

Then 2.8 light-years, then 2.7 light-years, until it is 1 light-year away.

At this moment, Han Yang has manufactured more than 300 billion detectors in total, so that they are roughly evenly distributed around the blue giant star.

Among them, the closer to the blue giant star, the higher the protection level.

Within a range of 1 light-year, the density of detectors deployed by Han Yang suddenly increased. From a distance of 1 light-year to a distance of 1 light-month, space has shrunk many times, but the total number of detectors has increased to 1000 billion.

Within 1 light-month, the detector density increased again.

Moreover, starting from this distance, all detectors made by Han Yang, no matter what type they are, all have roughly the same shape, that is, a shape similar to a nail.

Facing the blue giant star, there is a layer of circular nail caps with a larger diameter. This layer of nail caps will act like a shield, protecting the main facilities behind them as much as possible.

After the nail cap, a cylinder extends. Inside the cylinder is the detection module of the detector made by Han Yang, which is either gamma rays, gravitational waves, or neutrinos.

At this distance, the radiation from the blue giant star is already quite intense, and the detector must consider protection and heat dissipation. In a vacuum, heat can only be transferred through radiation, which is less efficient. Han Yang can only create a cylinder shape to dissipate excess heat as much as possible to protect the core device.

In this way, Han Yang gradually extended towards the blue giant star at the core. And the closer to it, the higher the density of various detectors.

When the distance shortened to only 10 billion kilometers, the laying of detectors came to an abrupt end.

But the production of detectors did not stop. Instead of stopping, Han Yang actually created more.

In such a vast space between 10 billion kilometers and 3 light years away from the blue giant, Han Yang has only laid a total of no more than 3000 billion detectors.

But within 10 billion kilometers alone, Han Yang has prepared a total of more than 4000 billion detectors!
Assuming that the average mass of a detector is 4000 tons, this is a total mass of trillion tons!

As an analogy, the total mass of the Earth's atmosphere is only about 5.15 trillion tons. At this moment, Han Yang built a detector equivalent to about 80% of the total mass of the earth's atmosphere, preparing to lay it around the blue giant!
The reason why it is not laid over at this moment is because even if the blue giant star has not exploded yet, the radiation around it is too intense. Even a detector specially designed for the environment around the blue giant star cannot survive in such an environment for too long. , it can work normally for up to ten hours.

To lay it down now is basically to throw it away in vain.

Han Yang planned to wait until a few hours before the supernova explosion to lay it.

To this end, Han Yang specially developed a special heavy-duty space carrier.

One such space carrier can carry more than 100 billion tons. But at the same time, it has no faster-than-light navigation module, no weapon system, and no conventional defense system. It only has some defense facilities customized for the surrounding environment of the blue giant star, and some high-power thrusters.

In this case, it will be much simpler to build. In the time it takes to build a regular space carrier, Han Yang can build 100 such space carriers.

It's nothing more than a pile of materials.

Such a space carrier, or to be more precise, is a super large transport ship within the star system. Han Yang built 40 of them in one go, and then installed all the detectors into this space carrier. Likewise, They are distributed roughly evenly about 10 billion kilometers around the blue giant star.

Here, the space carrier's thick armor and protective shields can last for a long time.

Everything has been arranged at this moment. All kinds of detectors have been built. The detection plan has also been formulated and completed.

Just waiting for the final moment to arrive.

According to Han Yang's estimation, it has been less than ten years since the supernova explosion of this blue giant star. To be more specific, it is within a total of eight months between the sixth month of the seventh year and the second month of the eighth year.

Han Yang was not idle during this period, but controlled the detectors that had been laid out on the periphery, collecting as detailed information as possible on the status of the blue giant star at this moment.

Even if it hasn't exploded yet, these preliminary process data are of great value and are indispensable.

At the same time, Han Yang also used his spare computing power again and began to create a huge number of one-time detectors, just like the one he used to detect the neutron star. After they were built, they were thrown directly towards the blue giant star. That may only be a few microseconds, or even a few nanoseconds, so get as close as possible to detect it.

Under this situation, huge amounts of data began to be generated continuously, and then stored by Han Yang.

Of course, with Han Yang's own ability at the moment, there is no way to analyze these data too deeply. In other words, even if enough data is collected, Han Yang cannot advance to the sixth level on his own.

Han Yang had already noticed this as early as when humans were promoted to level five civilization.

Although his computing power is sufficient, his wisdom is not a simple superposition of computing power. Without the wisdom of billions of scientists in human civilization, I simply do not have enough inspiration and direction to expand the theoretical system to sufficient width and depth.

During this trip to the Canis Major Dwarf Galaxy, Han Yang had no intention of completing the breakthrough on his own. His goal was originally to collect data and then bring the data back.

By then, the combination of myself and human scientists will have great hope to truly break through this barrier.

Time passed slowly as Han Yang waited. During this period of time, this blue giant star continued to express its enthusiasm into space.

Han Yang noticed that its radiation intensity has been continuously increasing. The luminosity reaches the Eddington limit or even exceeds it more and more times. And every transcendence means that the mass of the Earth is thrown out, ranging from ten to dozens of Earths.

Three years have passed, and Han Yang has framed the final outbreak time period within four months. Three more years passed, and the time was framed to one month. After that, the time was framed to five days, and finally it became three days.

Within the next 72 hours, this blue giant star will definitely explode as a supernova!
At this point, the prediction of the explosion time has reached its limit and cannot be further accurate. The 4000 billion detectors prepared by Han Yang can only survive the current radiation intensity for no more than ten hours.

And laying them takes time.

Based on the laying plan that Han Yang has prepared for hundreds of years, it only takes about seven hours to lay all 4000 billion detectors in the appropriate locations.

This poses a problem for Han Yang: if it is laid early, it is very likely that the survival time of these detectors will be exhausted, and as a result, it will not explode, and everything will be wasted;
If it is laid late, it is possible that Han Yang will explode before it is laid, which is also a waste.

The time must be neither too early nor too late, just right.

This conflict seemed irresolvable, but Han Yang did not panic at all.

He was still waiting quietly.

Because Han Yang knew that the prediction accuracy could not be further improved through external large models, but he could use another method to more accurately predict the time when a blue giant supernova explodes.

Before the explosion actually occurs, this huge star will proactively remind Han Yang.

While waiting patiently, a neutrino telescope closest to the blue giant suddenly reported data to Han Yang.

The number of neutrinos it detected suddenly increased dramatically! (End of chapter)
