Chapter 466 All Destruction
At this moment, the blue giant star in front of Han Yang did not change much from before.

It is still burning hot, radiating its enthusiasm into the surrounding space wantonly.

But the number of neutrinos released from its core increased by a trillion times in an instant.

As we all know, neutrinos are extremely penetrating. On average, 500 billion neutrinos penetrate every square centimeter on the earth per second.

But these neutrinos will not have any impact on the human body, let alone the earth.

Moreover, neutrinos are extremely small and light, with extremely low average energy.

The basic principle of radiation damage to the human body is that external photons or nuclei destroy the chemical structure between the particles that make up the human body because the penetrating power is too weak and the energy is too high.

So generally speaking, although neutrino radiation is also radiation, it is impossible to cause harm to the human body similar to nuclear radiation.

But at this moment, due to the huge explosion of neutrinos, the number of neutrinos has increased extremely around the blue supergiant star that is about to explode. According to Han Yang's calculations, at this moment, the neutrino radiation alone can reach the point where an entire planet can be destroyed in an instant. The point where a healthy human body is killed!

This means that the number of neutrinos has reached unimaginable levels.

Such a marvelous scene, which provides an overview of the entire universe and countless intense physical processes, can only be found around supernovae.

This is a unique sight in the entire universe.

Relying on neutrino radiation to kill life? Absolutely ridiculous! But such a ridiculous scene is happening here right now.

Han Yang couldn't help but marvel at this scene.

But at the same time, he realized more clearly that the sudden burst of neutrinos at this moment was the early warning sent to him by the blue supergiant star.

At this moment, there is no ordinary stellar material in the inner core of this blue supergiant. There, it has become a white dwarf star, a white dwarf star mainly composed of iron and nickel elements, which is larger than its companion star.

During the long evolution, the hydrogen and helium elements that make up this star continue to fuse until they are fused into nickel-56. Nickel-56 decays radioactively into iron-56.

But iron and nickel have a quality that is unlike any element lighter than them.

Its binding energy per unit nuclear is the highest among all elements.

This means that even if iron and nickel can fuse, their fusion will not release energy to the outside world, but will absorb energy.

But at this time, the star itself will not collapse. Because although the core no longer releases energy but absorbs energy, the energy released by fusion in other parts is still enough to support the existence of the star.

So this iron-nickel core keeps growing like this, getting bigger and bigger. But when their mass grows to about 1.44 times the mass of the sun, everything will become different.

Because the reason why this iron-nickel core can maintain its own density is entirely supported by electron degeneracy pressure. This is the same as any white dwarf star.

But when its mass reaches 1.44 times the mass of the sun, the electron degeneracy pressure is no longer enough to support the external pressure.

Then the collapse from the inner core begins.

When the collapse begins, the temperature of the core rises extremely, and the super strong gamma rays will decay the iron atoms into helium atoms and free neutrons. The helium nuclei will further undergo anti-beta decay and become neutrons and neutrinos.

All of this happens inside the star and cannot be detected by the outside world. Most of the particles generated during this process are blocked by the dense and thick stellar material and cannot be released to the outside world.

But neutrinos are different.

The penetrating power of neutrinos is so strong that even such thick and dense stellar material cannot block it. It can penetrate the star and be released to the outside world almost without any hindrance.

Han Yang knew that it was precisely because of this that he suddenly detected a huge amount of neutrinos.

The detection of a huge amount of neutrinos means that the iron-nickel white dwarf core at the core of the star has begun to collapse, which means that the preparatory work for a supernova explosion has begun.

Although it still maintains a roughly normal appearance on the outside, the core has collapsed.

Once the preparatory work begins, as measured by Han Yang, after about eight hours - this part of the time is used for various vibrations and the transfer of energy, particles, and matter within the star - the real supernova will explode. It's about to begin!

That's when the black hole will actually form!
In Han Yang's opinion, the scene at this moment was nothing more than the blue supergiant screaming at him with a big loudspeaker: "I'm about to explode! I'm about to explode! About eight hours later." I'm about to explode!"

Han Yang's spirit suddenly cheered up.

He crossed the vast distance of tens of thousands of light-years between river systems, risked his way through the deep space shock monitoring network deployed by the founder civilization, and sacrificed millions of warships and hundreds of millions of elite warriors from the Greenoka civilization. Luo Tu The huge risks that civilization has taken in order to separate human civilization from the Silver Alliance, as well as the struggle and sacrifice of human civilization for tens of thousands of years, the sacrifice of so many heroes, and the vast and long war with strange beings after arriving in the galaxy. , there are still hundreds of years to go all out to build, what is all this for?
Not just for now!
Isn’t it just to see with your own eyes the formation process of a macroscopic black hole?

At this moment, Han Yang poured all his computing power into the 40 heavy space carriers deployed one billion kilometers away from the blue supergiant.

On each space carrier, a total of more than 1 high-power thrusters are started at the same time, pushing them towards the blue supergiant at the same time.

During this process, all the huge hatches on the space carrier were opened, and inside each space carrier, up to one million various detectors came out, like a seeder sowing seeds. He entered space and quickly maneuvered towards where he should be.

Keep going, keep spreading. 40 heavy space carriers and a total of 4000 billion detectors.

Seven hours later, all the detectors were deployed.

At this moment, there are a total of 7000 billion detectors surrounding this blue giant star!
Especially these detectors that exist within a range of 10 billion kilometers.

They are spherical as a whole and wrap around the blue supergiant star from different directions.

Their number is so large that it has seriously weakened its brightness - from the outside, it seems as if the brightness of this blue supergiant suddenly weakened a lot on the eve of its explosion.

It's like a cover appeared on the outside, covering it directly.

This reminded Han Yang of a device that people had fantasized about in the early days, the Dyson sphere. Build a sphere around the star to maximize the radiation energy from the star.

However, with the development of science and technology, Han Yang has long confirmed that devices such as Dyson balls are not necessary at all. The reason is simple. A civilization that can create a Dyson sphere does not need such a backward and inefficient energy acquisition device.

Civilizations that need this kind of energy device simply don't have the ability to create a Dyson sphere.

Therefore, no matter high-level civilization or low-level civilization, no one will waste their efforts on Dyson Sphere.

But at this moment, Han Yang's detection device used another method to roughly achieve an effect similar to a Dyson sphere.

From the perspective of the supernova explosion model, this sudden decrease in brightness is completely unscientific and impossible to exist. If any civilization could see this scene, they would be shocked.

But now, Han Yang has no mind to care about those details.

When Han Yang quickly laid out all the detectors, the brightness of the blue supergiant had increased again and the radiation became more intense.

The violent radiation and energy hit these small detectors like stormy waves, causing irreversible damage to them almost instantly. If this situation continues, it will only take a few hours for them to be completely damaged.

But it doesn't matter, Han Yang didn't even think about recycling them.

At this moment, Han Yang knew that there were more violent physical processes taking place inside the star.

The iron-nickel white dwarf existing in the core of the star has now collapsed into a neutron star. The interior of the star is already empty. The huge amount of material outside the star has lost its core support and violently impacts downward onto the neutron star. Its speed can even reach more than 100,000 kilometers per second.

They violently collided with the neutron star, violently transmitting even greater pressure to the interior. The mass of the neutron star increased rapidly, and at the same time, the impact caused an indescribably violent shock wave.

The shock wave spread outward, reaching almost every particle that made up the star in an instant. As a result, each particle acquires enough energy to escape the star's gravity.

The core is squeezed, causing more material to fall onto the neutron star, rapidly increasing its mass until it exceeds the Oppenheimer limit - this is the mass limit of the neutron star. Once it exceeds this mass, it will Because its own gravity is too great, the neutron degeneracy pressure cannot support its body, and it will continue to collapse irreversibly until a black hole is formed.

At the same time as the core squeeze, the external burst occurs.

The violent shock waves and huge energy caused every particle outside the star to explode to the outside world.

Then a real supernova explosion occurred.

Han Yang saw that in almost an instant, the brightness of this single star rose to the point where it exceeded the brightness of the entire Milky Way.

Truly endless light and heat burst out from it, exploding towards the surroundings in an unstoppable manner.

Compared with the real supernova explosion, the previous nova explosion caused by Han Yang's initiative from the white dwarf star was basically a firefly competing for the brightness of the bright moon.

However, even a firefly like the nova explosion was enough to destroy most of Han Yang's fleet and most of the fifth-level strange beings, not to mention the detectors Han Yang was laying down now.

If they are strange lifeforms, their observation of stars is continuous. Before the supernova explosion, they will open a long enough distance and retreat while observing, always keeping themselves in a safe place.

But Han Yang is obviously not prepared to remove these detectors.

Therefore, the batch of more than 100 billion detectors that Han Yang had just laid out to the nearest distance to the star, which was only million kilometers away, were directly destroyed without even a splash of water when the supernova energy arrived.

But... the protective devices specially designed by Han Yang for harsh environments allowed them to sustain for hundreds of millions of seconds in the face of this violent energy, and collected data for hundreds of millions of seconds. , like a sudden glimpse, a very brief glimpse at the real changes when a supernova explodes and a macroscopic black hole is formed at an extremely close distance.

Next to usher in the baptism of supernova energy explosion is the second batch of 100 billion detectors about 1.2 million kilometers away from the star.

They were also destroyed in an instant, but before being destroyed, a single detector also peered for an average of about a few hundred millionths of a second.

Then there are detectors 1.3 million kilometers away, then 1.4 million, 1.5 million...

Han Yang's many detectors are like prisoners lined up waiting to be executed, and the energy released by the supernova explosion is like soldiers holding machine guns.

Destruction, destruction, nothing but destruction or destruction.

In less than an hour after the supernova explosion began, a total of 4000 billion detectors deployed by Han Yang within a billion kilometers of the star were all destroyed!
The reason why it takes an hour to be completely destroyed is not because these detectors can withstand the violent energy blow, but because even if a supernova explodes, its energy transfer cannot exceed the speed of light.

It takes a certain amount of time to cover the distance of one billion kilometers. After the energy arrives, it basically takes no time to destroy these detectors.

With the star as the core and the surrounding layers of detectors arranged by Han Yang, they are constantly being swallowed up by the energy released by the supernova explosion at the speed of light.

However, before each layer of detectors is destroyed, a little bit of data about the supernova explosion can be accumulated.

Whether it is neutrinos, gravitational waves, dark energy, gamma rays, X-rays, visible light, infrared, etc., all of them are in urgent need of Han Yang.

Han Yang just let the detector he spent a lot of energy and resources to create be destroyed mercilessly.

Time passed slowly, and three years passed in the blink of an eye.

The energy from the supernova traveled across a distance of three light years, mercilessly destroying Han Yang's outermost circle of detectors.

At this point, all Han Yang's detectors were destroyed and no one survived.

Even if the distance is as high as three light years, the energy of the supernova explosion is enough to destroy Han Yang's detector created by the fifth-level civilization.

3.2 light-years away, using the stars as a shield to avoid the first wave of the most violent energy impact, Han Yang controlled the telescope and pointed it in that direction again.
