Pulsar, a type of neutron star that rotates at high speed.

It is not uncommon in space, as early as 2022, humans have discovered more than 600 pulsars in space observations.

These extreme objects are capable of periodically emitting pulsed signals, mostly about 10 kilometers in diameter, and rotate extremely fast.

And not all neutron stars are pulsars, as the smaller and more massive the star, the shorter its rotation period and the stronger the pulse signal. It takes almost twenty-four hours for the Blue Star to rotate around in one week. And the rotation period of pulsars is as small as a few tenths of a second! To achieve such autobiographical speed, not even a white dwarf.

Therefore, only neutron stars that rotate at high speed can play the role of pulsars.

But if that's all there is to it, pulsars are nothing more than that.

Compared to the magnetars that Lu Yu once encountered in the Alliance of Conscious Life Forms, pulsars are more like extreme celestial bodies that can be seen everywhere in the universe, and they can't make Lu Yu take a second look at them.

But the pulsar shown by No. 7 is actually broadcasting information to the entire universe in the universal language of the universe.

As for the content, it's even stranger.

Ice? Ice cube?

Is water condensed into a solid?

This thing can't be said to be everywhere in the universe, but it can also be said to be everywhere.

It is also easier to make ice cubes, a large number of hydrogen and oxygen atoms react with each other to form water molecules, and then treat them at low temperatures to obtain ice.

Not to mention civilizations that have already used pulsars for broadcasting, and they don't even have such technology?

Lu Yu looked at the holographic projection in front of him, and then at No. 7, and always felt that there should be something wrong.

"Ice! That's right, it's ice! ”

No. 7's mouth stiffened: "Translated into the universal cosmic language, it is ice cubes, condensation of water!" ”

It's not that Lu Yu is suspicious, it's just too unbelievable.

After thinking about it, he also forwarded this information to Base Zero.

“…… Ice? ”

"For civilizations that have been able to use pulsar broadcasting, we think it's highly likely that their definition of [ice] will be different from what we humans define as ice."

"But...... It is also very likely that it was a lure to broadcast, using the low level of civilization to induce the surrounding civilizations that received the broadcast to go to the ......"

In terms of normal logic, at the level of planetary-level civilization, it is impossible to emit electromagnetic wave information facing the universe, because these electromagnetic signals will still attenuate badly in the space environment.

Taking Bluestar as an example, human beings began to use electromagnetic wave-based communication technology in the 20th century, and by the middle of the 20th century, electromagnetic signals were integrated into civilized life.

In the 21st century, it has been used for hundreds of years.

Electromagnetic waves can propagate at the speed of light in a vacuum environment, and if there is a civilization in the vicinity of the blue star as the core, then they have received electromagnetic signals if there are civilizations in the vicinity for nearly 100 light years.

But in fact, the electromagnetic waves emitted by humans can attenuate to the blind sound at most as far as the Oort Nebula, and they can no longer read any information. @精华\/Shuge Error-free Debut~~

Unless human beings can really discover the mirror gain reflection effect of solar energy, and carry out the emission of the energy level of civilization.

Otherwise, if you observe the blue star from Proxima Centauri, you will only see that there is silence there, without the slightest trace of civilization.

Planetary civilizations are silent bacteria to the universe, and it is extremely difficult to make their own voices.

The civilization in front of us has begun to make its own voice, even using an extreme celestial body.

At the beginning, the Qing clan of the sixth-level civilization could only absorb a star as an energy source for gravitational wave broadcasting, and this civilization has been able to transform a neutron star to be used as a broadcasting station.

Now, however, the message is being broadcast to get other civilizations to teach them how to make ice.

That's where it gets interesting.

Lu Yu, who had just thought that he had gained nothing, suddenly became interested.

It's not that he is bold, it's just that the silver star has proved in practice that the advanced civilization that has mastered space technology seems to have no way to take it, and can only pull the silver star into the black hole and try to die together.

It's not like to look at this strange broadcast. (This chapter is not finished!) )

Chapter 31: Unspeakable Ice

In vain, I came across this galaxy that resembles the Milky Way.

"Locked its coordinates? Let's go over and see. @精华\/Shuge Error-free Debut~~"

Lu Yu's idea was quickly implemented, and the space jump under the control of No. 7 accurately came to a position ten astronomical distances away from the pulsar.

A pulsar with a diameter of only 10 kilometers is not even comparable to some asteroids in terms of size, but it has a strong presence in the universe!

The high temperature of the blue-white flame makes this pulsar appear extremely bright.

What's even more terrifying is its electromagnetic pulse signal and magnetic field, making it like a lighthouse in the universe, extremely eye-catching.

For nearly a light-year, this pulsar is a veritable forbidden zone for life, surrounded by a nebula at the end of the star, where high temperatures, high pressures, and strong magnetic fields cut off the basis for the birth of all carbon-based organisms.

Ten astronomical distances, which is about 1.5 billion kilometers.

At such a distance, observing a pulsar is like looking at dust from a distance of 100 meters with the naked eye.

There is no trace of civilization activity in the surrounding area, and this place, like many star fields in the universe, is silent and desolate.

Neutron stars are the densest stars other than black holes, and at the end of star evolution, after a supernova explosion due to gravitational collapse, it may become one of the few endpoints, a star between a white dwarf and a black hole formed by a star whose mass has not reached the point where it can form a black hole collapses at the end of its life, and its density is quite many times greater than that of any matter on Earth.

The tremendous pressure it generates during the eruption collapse causes a dramatic change in its material structure. In this case, not only the outer shell of the atom is crushed, but even the nucleus is crushed.

Protons and neutrons are squeezed out of the nucleus, and protons and electrons are squeezed together to form neutrons. Eventually, all the neutrons are squeezed together to form a neutron star. Obviously, the density of neutron stars cannot be compared to even white dwarfs composed of atomic nuclei. On neutron stars, there are a billion tons of matter per cubic centimeter.

It is only right that there is silence and desolation around such an extreme environment.

"Hello, civilization receiving information."

"Please guide us in making ice, okay?"

Again, this message is repeated over and over again, and the frequency of reception becomes more and more frequent because of the proximity to the source.

"The civilization that sent out the radio led us here, and it was neither a trap nor a clear purpose...... Isn't it a space hoax? ”

"The local civilization is so rude!"

It was the first time Lu Yu had encountered this kind of space joke, and it would take a lot of time and material resources to adjust the pulsar battery pulse to the extent that it carried information.

As mentioned earlier, the peculiarity of a pulsar lies in its fast spin, and the electromagnetic pulse emitted is also related to its rotation.

One is to adjust the rotation, and the other is to work in a gravitational field where only neutrons are allowed.

Transforming this extreme celestial body into a radio station is far more difficult than wandering with the Blue Star.

It took a lot of effort just to play a prank on space?

"Let's get closer."

With Lu Yu's command, the Silver Star flew through the hot space environment and approached the pulsar.

As in Magnetar time, the extreme conditions here did not affect the Silver Star in the slightest.

Lu Yu began to approach without any cover, and he didn't even attract the attention of the civilization that arranged all this.

It wasn't until the Silver Star got close to the nearly 100-kilometer position of the pulsar that something changed.

"Hello, civilization approaching us."

"Are you here to help us make ice?"

It's a signal from a pulsar, and while it's faint compared to the powerful electromagnetic pulse, it does carry a different message.

"Are these signals coming from a region of the surface of a neutron star?"

"Our current instruments are so affected by such extreme conditions that we can only collect some information......

The holographic projection of the feedback from Seven appeared in virtual reality, and there were already a large number of experts at Base Zero waiting for this first-hand information.

"There is a civilization that has set up a base similar to an observatory there, and the signal is transmitted from the observatory. (This chapter is not finished!) )

Chapter 31: Unspeakable Ice

Out? ”

"If that's the case, then this civilization has already been able to establish an observatory on a neutron star, so why bother with the help of a passing civilization to help make [Ice Cube]?"

"Judging from the current data and observations, there is no trace of technological creation there."

"Maybe it's using space technology? After all, normal matter can no longer maintain its original structure on neutron stars, so we can only use space technology to isolate the extreme environment, and at the same time isolate us from prying eyes. ”

Experts have a lot of opinions, and it is really difficult to directly grasp the situation in front of them for a while.

"Yes, we, the Horn Clan, are here to help you make [Ice Cubes]!"

"Please come out and talk to us."

For the impostor horn clan, Lu Yu is already extremely proficient.

If we have too little information now, then we will use the Dafa of communication.

Once the other party shows hostility, then you can try the propulsion function that Lu Yu spent three thousand points to reinstall.

If you dare to touch porcelain, you will taste the taste of space mud trucks!

"Great!"

"Thank you, Horned Civilization."

"We're right below your ship."

The answer was quickly transmitted, and the other party also revealed his position with great sincerity.

And No. 7 hurriedly overloaded all kinds of observation instruments, not hesitating to scrap them to capture the traces of the other party.

Then the observations were made, and all the experts were silenced.

Neutron stars emit millions of times more energy than the Sun, according to the world's electricity consumption. The total amount of energy it radiates in one second would be enough to use the Blue Star for hundreds of millions of years.

There is a layer of plasma on the outside of the neutron star, and a few more nuclei extend down to completely dissociate and disappear, and the neutron star material becomes a continuous neutron fluid with a small number of electrons and protons.

The reason for the silence of the Zero experts was that directly below the Silver Star, where it should have been a forbidden area for life, there were layers of regular fluctuations, as if they were greeting them.

Neutron star lifeforms?

Lu Yu suddenly thought of the previous planetary lifeform, didn't he expect this pulsar to be a similar lifeform?

No....... no.

Lu Yu looked at the holographic projection below, combined with a large number of observed data.

The magnetic field of a neutron star does not change at all when it produces action below. Compared to the fact that the whole neutron star is a living thing, it is more like that the neutrons on its surface have life characteristics.

But that's outrageous!

Neutrons, how is it possible to form the characteristics of life?

Although humans have conjectures such as Boltzmann's brain, it is only a conjecture and there is a real example in front of us!

You must know that the previous planetary life forms at least had the basis for forming a thinking circuit from the magnetic field, and then through tens of thousands of years, hundreds of millions of years of adjustment, consciousness was formed.

Neutrons are made up of two lower quarks and one upper quark.

Free neutrons, or the constituent matter of a neutron star, can only exist steadily for 15 minutes, then decay into protons and electrons, and soon new neutrons will be born to take over the place of decaying neutrons. Only neutrons in the nucleus of an atom become very stable.

In such a short period of time, not to mention how to construct a network of consciousness nerves, they may begin to decay and die in the moment they have cognition.

But in reality, neutron life forms were miraculously born.

In the communication with Lu Yu, these neutron lifeforms directly told them the information.

I don't remember when the group of neutrons they gathered together began to have the ability to think.

Even if they are clusters of lifeforms, their structure is not destined to have a long lifespan for their components.

There is only fifteen minutes of time, and each part has to rush before decay, attracting more neutrons to gather and become the carrier of the thinking circuit.

Their way of being is to continue through continuous iteration, replacing the previous decayed neutrons, and once they hesitate for a moment, the thinking circuit that their race has worked so hard to maintain will collapse.

For them, fifteen minutes is the length of a lifetime. In Lu Yu's communication, the neutron lifeforms below had already been rounded for two rounds.

。 (This chapter is not finished!) )

Chapter 31: Unspeakable Ice

But these neutron lifeforms have a very strange dream, they want to create [ice cubes] on the surface of neutron stars.

Summer insects, unspeakable ice.

Neither can neutron lifeforms.

A civilization that may have passed by by chance told neutron life many generations ago that there was such a material form as ice in the universe, and since then it has become a lifelong pursuit of neutron life.

Generation after generation.

Batch after group.

They may not even be able to pass on civilization and technology, but the dream of pursuing the state of [Ice Cube] has been passed on.

It may sound unbelievable that these extremely short lives, which may iterate in an instant, want to make ice on a neutron star?

For this reason, they did not hesitate to modify the neutron star to send a plea broadcast to the whole universe, knowing that their life forms were already so fragile that the modified neutron star might even extinct themselves.

This ice is not the condensation of water as defined by humans.

These neutron beings aspire to freeze the extremely dense matter on the neutron star.

Because for their extremely short life, the frozen state of neutron star matter may be the ultimate beauty. Initial Update@
