c465 A huge project

For a blue giant star that is about to explode as a supernova, it is difficult to get close to it for observation even in normal times.

Its material ejection is too violent, and its external radiation is too intense. This makes it difficult for any detector to get close to it. Or even if it gets close, it will not last long and will be destroyed.

However, compared with the actual supernova explosion, the radiation of this blue giant star in normal times is nothing.

Once a supernova explosion occurs, in that instant, the brightness of a single star can even suppress the brightness of the entire Milky Way, hundreds of billions of stars combined. With such intense radiation, I am afraid that no matter what kind of defense measures Han Yang takes, it will be useless.

In this case, how can we conduct effective close-range observations of the specific process of supernova explosions and the formation of macroscopic black holes?

Han Yang concluded that this is simply impossible.

But does this mean that Han Yang cannot obtain relevant data at close range?

Not really.

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

Han Yang had used this plan when human civilization was promoted to Level 5 and observed the neutron star.

That is, quantity for quality.

A single detector is enough, even if it can only observe and collect data for one microsecond or one nanosecond when a supernova explodes.

If one detector is not enough, use ten. If ten are not enough, use one hundred, one thousand, or even one hundred billion or one trillion!

As long as the number is large enough, enough observation time can be accumulated and enough data can be collected!

But compared with 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 dimensions, instead of just observing one point as before.

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 requirement requires different observation equipment. These observation equipment, such as neutrino telescopes, require a thick shielding layer, plus at least hundreds of thousands of tons of pure water, and 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, it will take more than one million detectors to accumulate one second of observation time. What a huge project is this?

This is just one type of neutrino observation. Adding other detection needs, the total amount of work is so great that even Han Yang feels a huge pressure.

“I am afraid that even if there is no Silver Alliance in the Milky Way, any level 5 civilization can freely detect supernovas and the formation process of macroscopic black holes. It is an unimaginable difficult thing to obtain enough data and become a level 6 civilization. It is a task that most level 5 civilizations cannot accomplish at all.”

Han Yang sighed slightly: “I am afraid that most level 5 civilizations will choose to rely on a long period of accumulation to complete the promotion, rather than thinking about obtaining enough data through one observation.”

The amount of work is too big? Then I will build fewer detectors. When a macro black hole is formed, I will only collect a little data. When a macro black hole is formed next time, I will collect more data.

In this way, time is exchanged for engineering quantity. Relying on a long period of time accumulation, enough data is collected bit by bit and the promotion is completed.

But this method is obviously not suitable for Han Yang. If that is the case, it is probably impossible to complete without tens of thousands of years of accumulation. But Han Yang does not plan to stay in the Canis Major dwarf galaxy for too long.

In this case, he can only play his engineering advantages again and exchange engineering quantity for time.

So, when there were only about 500 years left before the supernova explosion and the formation of a macro black hole, Han Yang turned his sword into a plow, put his horse in the mountains, idled more than one million warships, and invested almost all computing power in engineering construction.

Trillions, tens of trillions of robots, intelligent machines, millions of transport ships, aerospace motherships, ferry ships, and tens of millions of large factories on the surface of the planet, all started to work at the same time at this moment.

Han Yang went all out.

Under this circumstance, the first batch of 500,000 gamma-ray detectors were built.

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

They were transported by Han Yang to a place 3 light years away from the star, and stopped in the endless vast void, aiming at the blue giant.

After that, the first batch of neutrino telescopes were built.

These neutrino telescopes have the same protective power, but the mass of each one is much larger, reaching about 500,000 tons.

Han Yang built 10,000 units and also placed them 3 light years away.

After that, more than 1 billion detectors of various types were built and all placed there.

They are evenly distributed as a whole. With the blue giant as the center of the sphere and 3 light years as the radius, it faintly surrounds the blue giant.

Then came the second batch of detectors. This time, Han Yang placed them 2.9 light years away from the blue giant, with a total of about 1 billion.

Then 2.8 light years, 2.7 light years, and so on until 1 light year away.

At this moment, Han Yang has made a total of more than 30 billion detectors, which are roughly evenly distributed around the blue giant.

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

Within the range of 1 light year, the density of detectors deployed by Han Yang increased sharply. From 1 light year to 1 light month, the space is reduced many times, but the total number of detectors has increased to 100 billion.

Within 1 light month, the density of detectors increased again.

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

Facing the direction of the blue giant, there is a layer of round nail caps with a larger diameter. This layer of nail caps will play a role similar to a shield, protecting the main facilities behind as much as possible.

After the nail caps, a cylinder extends.

Inside the cylinder is the detection module of the detector made by Han Yang, which can detect gamma rays, gravitational waves, or neutrinos.

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

In this way, Han Yang extends little by little to the blue giant at the core. And the closer to it, the higher the density of various detectors.

When the distance is shortened to only 1 billion kilometers, the laying of detectors comes to an abrupt halt.

But the manufacture of detectors did not stop. Instead, Han Yang made more.

In such a vast space between 1 billion kilometers and 3 light years away from the blue giant, Han Yang has only laid a total of no more than 300 billion detectors.

But within a distance of 1 billion kilometers alone, Han Yang has prepared more than 400 billion detectors!

Calculated based on the average mass of a detector of 10,000 tons, this is a total mass of 400 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 has made detectors, which are equivalent to about 80% of the total mass of the Earth’s atmosphere, ready to be laid around the blue giant!

The reason why it is not laid at this moment is that even if the blue giant has not exploded at this moment, the radiation around it is too intense. Even detectors designed specifically for the environment around the blue giant cannot survive for too long in such an environment. They can only work normally for ten hours at most.

Laying it now is basically equivalent to throwing it away in vain.

Han Yang plans to wait until a few hours before the supernova explosion.

For this reason, Han Yang has specially developed a heavy-loaded special aerospace mothership.

This aerospace mothership can carry more than 10 billion tons. But at the same time, it has no superluminal navigation module, no weapon system and conventional defense system. It only has some defense facilities specially customized for the environment around the blue giant, and some high-power thrusters.

In this case, it is much easier to build. Han Yang can build 100 aerospace motherships of this type in the time required to build a regular aerospace mothership.

It’s nothing more than piling up materials.

Such aerospace motherships, or more accurately, super-large intrastellar transport ships, Han Yang built 400,000 of them in one go, and then installed all the detectors in this aerospace mothership, and also made them roughly evenly distributed about 1 billion kilometers around the blue giant.

Here, the heavy armor and protective shield of the aerospace mothership can support for a long time.

At this moment, everything has been arranged. Various detectors have been built. The detection plan has also been formulated and perfected.

Just waiting for the final moment to come.

According to Han Yang’s estimation, it is less than ten years away from the supernova explosion of this blue giant. 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.

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

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

At the same time, Han Yang also used the idle computing power again and began to create a large number of disposable detectors, just like the one used to detect the neutron star. After they were built, they were thrown directly at the blue giant star, relying on the time that might only be a few microseconds or even a few nanoseconds before it was destroyed, and they were detected as close as possible.

Under this situation, a huge amount 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. That is, even if enough data is collected, Han Yang can’t be promoted to the sixth level by himself.

As early as when humans were promoted to the fifth level of civilization, Han Yang had already noticed this.

Although his computing power is sufficient, wisdom is not simply the sum of computing power. Without the wisdom of billions or even tens of billions of scientists in human civilization, he does not have enough inspiration and direction, and cannot expand the theoretical system to a sufficient width and depth.

During this trip to the Canis Major dwarf galaxy, Han Yang did not intend to rely on his own strength to make a breakthrough. His goal was to collect data and then bring it back.

At that time, the combination of himself and human scientists will have great hope to truly break through this obstacle.

Time slowly passed while Han Yang was waiting. During this period, the blue giant star continued to show its enthusiasm in space.

Han Yang noticed that its radiation intensity has been constantly increasing. The number of times the luminosity reaches the Eddington limit or even exceeds it is increasing. And each time it exceeds, it means that the mass of at least ten or at most dozens of earths is thrown out.

Three years have passed, and Han Yang has framed the final explosion time period in four months. After another three years, the time was set to one month, and then it was set to five days, and finally to three days.

Within the next 72 hours, this blue giant 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 400 billion detectors prepared by Han Yang can only survive for no more than ten hours under the current radiation intensity.

And laying them also takes time.

With the laying plan that Han Yang has prepared for hundreds of years, it only takes about seven hours to lay all the 400 billion detectors to the appropriate positions.

This brings a problem to Han Yang: if it is laid early, it is very likely that these detectors will run out of life time, and it will not explode, and everything will be wasted;

If it is laid late, it is possible that it will explode before Han Yang has finished laying it, which is also a waste.

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

This contradiction seems unsolvable, but Han Yang is not panicked at all.

He is still waiting quietly.

Because Han Yang knew that the external large model could not further improve the prediction accuracy, but he could use another method to more accurately predict the time when the blue giant supernova explosion would occur.

Before the actual explosion, this huge star would take the initiative to remind Han Yang.

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

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