Start sweeping the universe by rubbing the CPU with your hands - Chapter 468

c464 New stars!

At this moment, with the huge amount of hydrogen and helium that make up this gas planet rotating and falling onto the white dwarf, the brightness of the entire white dwarf has increased thousands of times compared to before.

Endless gas even formed a cloud around it, which spun around it crazily, rubbing violently against each other, and the energy rose rapidly, even forming obvious jets at the poles of the white dwarf.

Overall, the clouds surrounding this white dwarf at this moment are like a cradle.

The cradle of humans is used to raise newborns. At this moment, the cradle of the white dwarf is also nurturing some extremely terrible changes.

Although the radiation of this white dwarf is fierce at this moment, although it is enough to sweep across the entire star system, if it is placed in the solar system, even human civilization that has entered space and can even conduct interstellar navigation cannot withstand it.

But compared to the blue supergiant stars, which are already extremely violent and can easily throw out several or even dozens of Earth-masses, it is not enough, let alone causing major damage to the strange life clusters.

At this moment, it is nothing more than making the environment in the galaxy worse.

However, with the passage of time, with the near disappearance of the gaseous planets, and with most of the 900 trillion tons of hydrogen and helium that make up it falling on the white dwarf, a critical point is finally reached.

The gravity on the surface of the white dwarf is extremely strong, even up to hundreds of thousands of times that of the earth. Under the compression of such strong gravity, all hydrogen and helium reaching the surface of the white dwarf will be extremely compressed.

Compression means an increase in temperature, and the temperature of these hydrogen and helium quickly rises to tens of millions or even hundreds of millions of degrees Celsius.

And this environment is similar to the core environment of a star.

In the core of a star, because of high enough temperature and pressure, hydrogen and helium will undergo nuclear fusion, converting mass into energy, allowing the entire star to emit light and heat.

So, what will happen if the surface of a white dwarf has an environment similar to the core of a star?

Obviously, the hydrogen and helium here will also undergo nuclear fusion.

Nuclear fusion will release energy, which will cause the temperature and pressure on the surface of the white dwarf to further increase.

If it is in the core of a normal star, the increase in temperature and pressure caused by the energy will cause the star to expand due to the excessive internal pressure.

When the star expands, the internal pressure will naturally decrease, the temperature will also decrease, and the nuclear fusion rate will naturally slow down.

In this way, the star can form a dynamic balance between internal pressure-nuclear fusion-volume, and roughly maintain a stable nuclear fusion rate, that is, not too fast or too slow.

But when it comes to the surface of the white dwarf, this dynamic balance regulation mechanism will fail.

Hydrogen and helium undergo nuclear fusion, further increasing the temperature and pressure. The increase in temperature and pressure will lead to greater pressure and faster fusion rate.

But the gravity of a white dwarf is stable and will not decrease due to the increase in pressure. Therefore, the more nuclear fusion, the higher the pressure and temperature. The higher the pressure and temperature, the faster the nuclear fusion rate.

What consequences will this lead to?

Very simple, this will inevitably lead to catastrophic, uncontrolled chain fusion of all fuels available for fusion in a short period of time, and all of them will be fused in a very short time.

This mechanism is somewhat similar to a hydrogen bomb. The difference is that the largest equivalent hydrogen bomb made by humans has a TNT equivalent of only about 200 million tons. Converted into mass, plus the reaction ratio of nuclear fusion, such a hydrogen bomb with such great power that can even change the earth’s crust, the total mass of hydrogen elements participating in the reaction is only about 1.3 tons, of which less than 10 kilograms of hydrogen elements are converted into energy.

At this moment, the uncontrolled, catastrophic chain reaction nuclear fusion occurred on the surface of this white dwarf. How much hydrogen and helium elements are involved in the reaction?

Almost as high as 900 trillion tons!

Such a large mass, because of the super strong gravity of this white dwarf, reacted in almost an instant, and the energy released was so powerful that it was almost unimaginable.

In comparison, the energy released by the gaseous planetary gas colliding with the white dwarf in the early stage was just a drizzle, not worth mentioning at all.

The energy that erupted at this moment was what Han Yang really expected.

In this moment, the brightness of the white dwarf even climbed to tens of thousands of times the original brightness. At the peak moment, it even grew to a level comparable to that of a blue giant star.

The truly violent energy began to sweep across the entire star system.

At this moment, the first to bear the brunt were not the strange life forms, but Han Yang’s warships.

A fleet led by dwarf planetary warships with more than 5,000 small and medium-sized warships.

Facing this huge energy impact like a tsunami, Han Yang’s proud multi-layer dark energy shield, like a fragile eggshell, did not even last a microsecond and shattered directly.

The super-strong alloy that constituted the warship was vaporized in an instant and completely turned into cosmic dust.

After that, there was the strange life form similar to the pterosaur that Han Yang had encountered earlier, which had caused him great trouble in the early stage.

This strange life form was huge, highly maneuverable, and extremely defensive. Often, even Han Yang’s warships could not break their defenses even with their head-on bombardment.

At this moment, there were more than 10,000 of these monsters here.

After Han Yang’s fleet was destroyed, a violent energy shock came to them.

Then, the next moment, the powerful monster that gave Han Yang a headache was also like a little chicken. Its defense was broken in an instant, and it was vaporized and disappeared without even a cry.

Then, there was a large group of combined strange life forms tens of millions of kilometers away from the white dwarf.

This kind of strange life can be combined into a larger combination to obtain more powerful combat power. In the previous war, they also caused great trouble to Han Yang.

But at this moment, this combination composed of hundreds of thousands of sub-bodies was also vaporized and disappeared in an instant.

Then, there were Han Yang’s hundreds of billions of interstellar mines, hundreds of thousands of spy satellites, hundreds of thousands of small unmanned warships, a large number of interstellar turrets, and a huge number of Zerg sub-worms, hundreds of billions of strange life forms…

No matter what it was, whether it was a strange life form or a technological creation, whether it was a small interstellar mine or a huge satellite-class warship, facing this huge energy that could almost destroy the world, all of them had no resistance and were vaporized and disappeared in an instant.

The violent energy from the white dwarf really swept across the entire galaxy.

It was like a powerful disinfectant, and all the technological creations and strange life in this galaxy were like fragile bacteria.

Wherever the disinfectant reached, all the bacteria there would die.

The galaxy, which was originally in turmoil, completely quieted down under the energy impact of this white dwarf.

It was quiet in space, and not even a broken arm or debris could be seen.

Han Yang’s powerful fleet was almost completely destroyed. The strange life cluster was also almost completely destroyed.

The reason why it was not really completely destroyed was that there were still some existences in this star system that could withstand such a violent energy impact.

That was the macroscopic celestial body.

Dwarf planets or large planets.

Although the atmosphere of planets with atmospheres was directly stripped away, the surface of planets without atmospheres was directly scorched, and gaseous planets set off violent storms, they could still be regarded as shields because of their large enough mass and thickness.

In the explosion, those who happened to be hiding on the back of the planet would be lucky enough to escape.

But it is not the same for those in space. No matter how powerful they are, they will all be destroyed.

Han Yang controlled the few probes that survived by chance to leave the back of the planet and began to observe the current state of the galaxy.

At this moment, Han Yang, who saw these scenes, could not help but be shocked.

Although these changes were all caused by himself. But theoretical calculations are different from what you actually see.

“This is a nova…”

Han Yang sighed silently in his heart.

That’s right, the violent energy explosion process happening on the white dwarf at this moment is actually not uncommon in the universe. Including human scientists, all intelligent civilizations that have reached a certain level have studied this and have given it a special term, nova.

Nova refers to a type of star whose luminosity suddenly increases violently. Because the luminosity suddenly increases, they can be seen with the naked eye, which was originally invisible to the naked eye. It looks like a new star in the sky, so it has the name of nova.

With the development of science and technology, people have a better understanding of novae, and gradually divided them into more types, such as supernovae and hypernovae.

The word “nova” specifically refers to the physical process of explosion caused by the accretion of matter by a white dwarf.

However, under natural conditions, the nova process usually occurs when a white dwarf accretes matter from a companion star and accumulates enough fusion fuel to explode.

But here, the white dwarf is too far away from the blue giant star, and it is obviously impossible to accrete matter from the companion star, so Han Yang needs to manually feed a gas planet to trigger it.

Anyway, the material composition of gas planets and stars is similar, both hydrogen and helium. Accretion of stellar matter can cause an explosion, and accretion of gas planets can also cause an explosion, as long as the total amount of matter is sufficient.

It should be noted that although both are triggered by white dwarfs, type Ia supernovae and the nova explosions that are happening at this moment are two completely different types.

The so-called supernova, just from the literal understanding, can know that a supernova is a super-violent nova explosion process.

Its energy release is much larger than the nova explosion at this moment.

Type Ia supernovae are a type of supernova. Its original star was also a white dwarf, and the process was also caused by accretion of matter from the outside.

But it accreted too much matter, not only making the surface of the white dwarf have enough conditions to trigger chain nuclear fusion, but also because of the increase in gravity, the core temperature has increased greatly, and it will even increase to the point where the carbon and oxygen elements in the core of the white dwarf will fuse.

So, huge energy is released inside and outside, and the entire white dwarf is completely blown up. All the matter in the entire star will be transformed into high-energy radiation and impact the universe.

A white dwarf can only have one Type Ia supernova explosion in its lifetime, because once it happens, it will be completely blown up.

But the nova explosion at this moment can be repeated.

As long as there is enough matter, it can explode repeatedly. Of course, the energy intensity of a single explosion is naturally far less than that of a supernova explosion.

But for this moment, the nova explosion alone is enough to clear out most of the strange life in this star system.

Although most of his own fleet was also wiped out, Han Yang didn’t care.

Because at this moment, the huge fleet transferred from the neighboring star system has arrived.

After the nova explosion, although it has improved a lot compared to the peak period, it is still an extremely harsh interstellar environment. Up to one million warships, numerous automated combat facilities, and countless detection equipment are once again scattered in the interstellar space.

Han Yang began to look for the existence of each individual of the strange life, and killed them all in an orderly manner.

In this process, a large number of strange life forms began to choose to flee. But how could they be Han Yang’s opponent without their collective? They were often killed by Han Yang before they escaped for long.

Somewhat unexpectedly to Han Yang was that the fifth-level Zerg queen, which had almost undertaken all the logistics and transportation tasks in the previous war, did not die completely under the violent energy impact of the nova explosion.

Although most of its body was broken, and some places even had a loss of up to tens of thousands of square kilometers, its few parts were still ejecting larvae in twos and threes.

Han Yang sneered in his heart, and then mercilessly dropped thousands of high-yield quark fusion bombs, directly blowing it to death.

After the last few strange lives found were wiped out, the entire galaxy, except for the blue giant star that was still wantonly showing off its enthusiasm, finally became truly quiet.

At this moment, Han Yang suddenly felt a surge of pride in his heart.

He checked the long-distance communication network of the Canis Major dwarf galaxy and found that it was still quiet.

He looked into the depths of the starry sky, where it was still as peaceful and dead as ever.

In the past, Han Yang always felt that there seemed to be countless eyes in this vast starry sky, looking at him greedily and cruelly, ready to move in the dark, and could jump out at any time.

But now, with more than a dozen level 5 strange life clusters being wiped out by himself, the feeling of being spied on has completely disappeared.

The tranquility at this moment is the real tranquility.

“Who else?!”

Han Yang took the initiative to send a message to the hypercommunication network of the Canis Major dwarf galaxy, and then repeated these three words tens of thousands of times.

The hypercommunication network was still silent, without any fluctuations.

“No more? Very good.”

Han Yang stopped broadcasting the message and turned his attention to the blue supergiant in front of him.

Due to the impact of the nova explosion, its estimated explosion time has been brought forward again. At this moment, it is probably less than 500 years away from its actual explosion.

It’s time to go all out to observe. (End of this chapter)
