c466 Total destruction

At this moment, the blue giant star in front of Han Yang has not changed much from before.

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

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

As we all know, neutrinos have extremely strong penetrating power. On average, 50 billion neutrinos penetrate every square centimeter on Earth per second.

But these neutrinos will not cause 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 causing harm to the human body is that external photons or nuclei, because of their weak penetrating power and high energy, destroy the chemical structure between the particles that make up the human body.

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

But at this moment, around this blue supergiant that is about to explode, the number of neutrinos has risen extremely due to the huge explosion. According to Han Yang’s calculations, at this moment, the neutrino radiation alone can kill a healthy human body in an instant!

This means that the number of neutrinos has reached an unimaginable level.

Such a wonder can only be found around supernovas in the entire universe and countless intense physical processes.

This is a unique and strange scene in the entire universe.

Relying on neutrino radiation to kill life? It’s ridiculous! But such an absurd scene is happening here at this moment.

This scene made Han Yang marvel at it.

But at the same time, he realized more clearly that the sudden explosion of neutrinos at this moment was a warning from this blue supergiant to himself.

At this moment, the inner core of this blue supergiant is no longer an ordinary stellar material. There, it has become a white dwarf, a white dwarf 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 fuse into nickel-56. Nickel-56 will decay into iron-56 through radioactivity.

But iron and nickel have a different characteristic from all elements lighter than them.

Its nucleon binding energy per unit 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 body will not collapse. Because although the core no longer releases energy but absorbs energy, the energy released by the fusion of other parts is still enough to support the existence of the star.

So this iron-nickel core continues to grow, getting bigger and bigger. But when their mass grows to about 1.44 times the mass of the sun, everything will be different.

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

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.

So the collapse from the internal 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, and the helium nuclei will further decay into neutrons and neutrinos through anti-β decay.

All this happens inside the star, and the outside world cannot detect it at all. Most of the particles generated in this process will be blocked by the dense and heavy stellar matter and cannot be released to the outside world.

But neutrinos are different.

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

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

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

Although its exterior still looks roughly normal, its core has collapsed.

Once the preliminary work begins, Han Yang measures that in about eight hours – this time is used for the various vibrations and energy and particle and material forces inside the star – the real supernova explosion will begin!

The black hole will be truly formed at that time!

At this moment, in Han Yang’s view, this scene is no different from this blue supergiant holding a big speaker and constantly yelling at him: “I’m about to explode! I’m about to explode! I’m about to explode in about eight hours!”

Han Yang’s spirit suddenly perked up.

I crossed the vast distance of tens of thousands of light years between galaxies, risked breaking through the deep space shock monitoring network set up by the Creator Civilization, the millions of warships and hundreds of millions of elite soldiers sacrificed by the Greenoka Civilization, the huge risks taken by the Lotu Civilization to make human civilization break away from the Silver Alliance, and the struggle and dedication of human civilization for tens of thousands of years, the sacrifice of so many heroes, and the huge and long war between me and the strange life forms after arriving in the Milky Way, and hundreds of years of all-out construction, all of this, what is it for?

Isn’t it just for now!

Isn’t it just to see the formation process of a macro black hole with my own eyes!

At this moment, Han Yang’s entire computing power was poured into the 400,000 heavy-duty aerospace carriers deployed 1 billion kilometers away from the blue supergiant star.

On each aerospace carrier, the total of more than 10,000 high-power thrusters were activated at the same time, pushing them to approach the blue supergiant star at the same time.

During this process, the huge hatches on the aerospace carriers were all opened, and inside each aerospace carrier, a million various detectors all came out in a line, entering the space like a seed drill sowing seeds, and quickly maneuvered to where they should be.

Go forward and sow all the way. 400,000 heavy-duty aerospace carriers, a total of 400 billion detectors.

Seven hours later, all the detectors were sown in place.

At this moment, around this blue supergiant star, there are already a total of 700 billion detectors!

Especially those detectors within a range of 1 billion kilometers.

They are spherical as a whole, wrapping around this blue supergiant star from different directions.

Their large number even seriously weakened its brightness – from the outside, it was as if the brightness of this blue supergiant suddenly weakened a lot before the explosion.

It was as if a cover appeared outside and covered it directly.

This reminded Han Yang of a device that people had imagined in the early days, the Dyson sphere.

Build a sphere around a star to obtain the radiation energy from the star to the maximum extent.

But with the development of technology to this day, Han Yang has long confirmed that a device like the Dyson sphere is not necessary at all. The reason is very simple. A civilization that can build a Dyson sphere does not need such a backward and inefficient energy acquisition device.

A civilization that needs such an energy device has no ability to build a Dyson sphere.

Therefore, no matter whether it is a high-level civilization or a low-level civilization, none of them will waste energy on the Dyson sphere.

But at this moment, Han Yang’s detection device has roughly achieved an effect similar to the Dyson sphere in another way.

From the perspective of the supernova explosion model, this phenomenon of sudden brightness reduction at this moment is completely unscientific and impossible to exist. If there is a civilization that can see this scene, they should be very shocked.

But now, Han Yang had no intention 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 a storm, causing irreversible damage to them in almost an instant. At this rate, it would only take a few hours for them to be completely damaged.

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

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

The iron-nickel white dwarf in the core of the star had collapsed into a neutron star. The interior of the star was empty, and the huge amount of matter outside the star, because of the loss of core support, violently hit the neutron star, and its speed could even reach more than 100,000 kilometers per second.

They collided violently with the neutron star, violently transmitting even greater pressure to the inside. The mass of the neutron star increased rapidly, and at the same time, the impact caused a shock wave that was so violent that it was indescribable.

The shock wave spread outward, and in an instant it spread to almost every particle that made up the star. As a result, each particle obtained enough energy to break free from the star’s gravity.

The core compression caused more matter to fall onto the neutron star, rapidly increasing its mass until it exceeded the Oppenheimer limit – this is the mass limit of a neutron star. Once it exceeds this mass, it will be unable to support its body due to its own gravity, resulting in the neutron degeneracy pressure, and will continue to collapse irreversibly until a black hole is formed.

At the same time as the core compression, the external explosion occurred.

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

So a real supernova explosion occurred.

Han Yang saw that in almost an instant, the brightness of this single star climbed to a point that surpassed the brightness of the entire Milky Way.

Truly infinite and endless light and heat burst out from it, exploding towards the surrounding area with an unstoppable attitude.

Compared with a real supernova explosion, the nova explosion that Han Yang had initiated before, which originated from a white dwarf, was simply a firefly competing with the bright moon.

However, even a firefly like a nova explosion would be enough to destroy most of Han Yang’s fleet and most of the Level 5 strange life forms, not to mention the detectors that Han Yang had laid down at the moment.

If it was a strange life form, they would continuously observe the star. Before the supernova exploded, they would pull away enough distance, retreat while observing, and always keep themselves in a safe place.

But Han Yang obviously did not intend to withdraw these detectors.

Therefore, the batch of more than 10 billion detectors that Han Yang had just laid down, which was only 100 million kilometers away from the star, were destroyed directly without even a splash when the supernova energy arrived.

But… Han Yang’s protective devices designed specifically for harsh environments ultimately allowed them to withstand this violent energy for about hundreds of millions of seconds, collecting data for hundreds of millions of seconds, just like a glimpse, very briefly and at a very close distance, to peek at the real changes when the supernova exploded and the macro black hole was formed.

The second batch of 10 billion detectors about 120 million kilometers away from the star were baptized by the supernova energy explosion.

They were also destroyed in an instant, but before the destruction, each detector also peeked for an average of about hundreds of millions of seconds.

Then there were the detectors at a distance of 130 million kilometers, then 140 million, 150 million…

Han Yang’s many detectors were like prisoners waiting in line to be executed, and the energy released by the supernova explosion was like a soldier holding a machine gun.

Destruction, destruction, nothing but destruction.

Less than an hour after the supernova explosion began, a total of 400 billion detectors deployed by Han Yang within a billion kilometers of the star were completely destroyed!

The reason why it took an hour to completely destroy them was not because these detectors could withstand the violent energy blow, but because even if it was a supernova explosion, its energy transfer could not exceed the speed of light.

It takes a certain amount of time to transfer this distance of one billion kilometers. After the energy arrives, it basically does not take time to destroy these detectors.

With the star as the core, the layers of detectors arranged by Han Yang around it were constantly swallowed by the energy released by the supernova explosion at the speed of light.

And before each layer of detectors was destroyed, it could accumulate a little bit of data about the supernova explosion.

Whether it was neutrinos, gravitational waves, or dark energy, gamma rays, X-rays, visible light, infrared rays, etc., all of them were what Han Yang urgently needed.

Han Yang just let the detectors that he had spent a lot of energy and resources to create be destroyed so mercilessly.

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

The energy from the supernova traveled a distance of three light years, mercilessly destroying the outermost circle of detectors that Han Yang had laid.

At this point, all of Han Yang’s detectors were destroyed, and none survived.

Even at a distance of three light years, the energy of the supernova explosion was enough to destroy Han Yang’s detectors, which were created at the fifth level of civilization.

At a distance of 3.2 light years, using the stars as a shield to avoid the first wave of the most violent energy impact, Han Yang manipulated the telescope to point in that direction again.
