Black technology: starting with space jump machine

Once, the most valuable things in this spaceship were undoubtedly the various instruments that were repeatedly disassembled and assembled, as well as the Zerg scientists who were forced to operate and constantly explain the functions of the components.

But now, the star map is out!

Especially when there are similar coordinates of the Milky Way on the star map, everything has changed.

After walking such a long way and crossing so many stars, isn’t it just like when you were forced to jump away from Mars, you want to return to the familiar blue planet.

Searching and searching, going around in circles.

Until Lu Yu looked at the holographic projection of the galaxy in front of him, he couldn’t believe that the hope of returning to the blue planet appeared in front of him so inadvertently.

The Milky Way is a barred spiral galaxy where the solar system is located. It is a type of spiral galaxy with an elliptical disk shape and a huge disk structure. The latest research shows that the Milky Way has four clear and symmetrical spiral arms, which are 4,500 light years apart, and the number of stars in it is about 100 billion to 400 billion.

Don't look at the large number of stars. If the Silver Star can return to the Milky Way, it will be easy to lock the solar system.

From the Blue Star, the center of the Milky Way is the brightest area of ​​the Milky Way, and its direction is Sagittarius. From Sagittarius, the hazy white light band seems to pass to the back of Auriga. The light band then continues the rest of the way back to the vicinity of Sagittarius, dividing the celestial sphere into two roughly equal hemispheres.

In this way of comparing the two, Lu Yu can easily find the position of the Blue Star by jumping a few more times in the Milky Way. It's no wonder that Lu Yu immediately got excited.

"Compared with the Milky Way star map observed by Base Zero, the similarity rate is more than 80%."

"But because it is 20 million light years away from the Zerg observation point, the specific situation of the galaxy has evolved into a completely different appearance, but after calculation, the probability that the galaxy is the Milky Way is more than 50%."

After the brief report of No. 7, the star map that had just been transcribed was displayed on the holographic projection.

A barred spiral galaxy with a diameter ranging from 100,000 to 180,000 light years. It has about 100 billion to 400 billion stars and possibly 100 billion planets.

It has dense gas and dust, is an oblate spheroid, has a huge disk structure, and is composed of a bright and dense core, two main spiral arms and two unformed spiral arms, which are about 4,500 light years apart.

"This is very similar to the structure of the Milky Way!"

"Are you stupid? The basic structure of the barred galaxy is basically the same as this!"

"But this is the galaxy that is most similar to the Milky Way since Lu Yu entered the universe."

A large number of astronomers discussed that if Lu Yu could return to the solar system before the unknown fleet arrived, the safety of the blue planet would be basically guaranteed.

At the same time, Lu Yu also left a large number of assets in the universe.

Not to mention the giant spaceship in front of us, as long as the space bubble obtained from the folded space can be given to human civilization, the entire civilization can enter the interstellar era directly without relying on the Silver Star.

Moreover, it is the lizard civilization, and the remains of the conscious life form alliance contain huge value.

Once Lu Yu returns, these things will no longer be things that humans can only see in the fog and cannot reach.

Scientists can go to the field to investigate, and then transport them back to the solar system to become human things.

The current Silver Star is no longer the space jump machine that can only randomly transmit. This thing has inestimable value for a civilization!

And Lu Yu has been drifting for so long. If he can return to the Blue Star to rest, then he may be able to complete his vision and start the next stage of evolution.

Leave as a human body, return as a human body, and then it will be a glorious evolution.

This is an idea that has been hidden in his heart, and even No. 7 doesn't know.

Since it is now a rare opportunity, how can we continue to wait in vain?

The energy system of the Silver Star was damaged. During this nearly one-year stay, it only stored energy 5 times.

But it is completely enough to detect the true and false Milky Way this time, but these Zergs have to find a way to arrange it.

It is also an energy problem. The cross-space communication system of the Silver Star can no longer be turned on for a long time, otherwise it will affect the charging of space jumps.

Therefore, how to squeeze the surplus value of the Zerg has become a problem.

But the problem is not big, the solution is sent up by the Zerg!

The advanced artificial intelligence suppressed by No. 7 soon turned into her shape.

This giant spaceship will still be managed by this artificial intelligence, and the Zerg inside will transcribe their technology tree into the universal language of the universe over and over again, and then No. 7 will receive it through regular cross-space communication and send it to Base Zero.

The arrangement is clear and obvious.

And if there is any abnormal movement, it will only waste a space jump for the Silver Star, while some Zerg will pay with their lives.

So there is such a wonder in front of us, a steel spaceship with the same size as Saturn has turned into a satellite of a super-earth, and it is also swallowing a large amount of mechanical debris, erasing the traces of the battle that has taken place here.

When the second and third fleets of the Zerg arrive, they will understand what a special surprise is.

From invaders to guardians, it can be regarded as a bad taste left by Lu Yu.

At the same time, Lu Yu did not forget to leave an order to his leather-covered man Nemo to conquer other continents, and how to implement it had already left a space bubble in his core that carried plans and computing power.

Once verified, you may be able to come back soon.

Thinking of this, Lu Yu did not hesitate and jumped directly out of the folded space where he had stayed for a long time.

………..

Directional space jump is full of unknowns.

Because the position of galaxies in the universe is not motionless. When the galaxy suspected to be the Milky Way was observed at the Zerg observation point, the light had already traveled in the universe for 20 million years.

The actual appearance of this galaxy is completely different from what is observed.

Even though No. 7's computing power has reached a level that would astonish even a ninth-level civilization, the results of this directional space jump are still unknown.

Maybe they jumped into the void of the universe in one breath, or maybe they jumped into the black hole.

When the starry sky outside the Silver Star came into view, Lu Yu understood that they had successfully reached their destination this time.

This is a large nebula with a length and width of more than ten light years. This nebula is a luminous nebula. There are three types of nebulae, namely luminous nebulae, reflection nebulae and dark nebulae. Luminous nebulae, as the name suggests, emit visible light themselves. A reflection nebula can reflect the light of other stars. A dark nebula has no stars nearby and no stars inside it. Therefore, it is invisible in the visible light band, but it can be found by looking for black areas in the bright background.

The Glowing Nebula is one of the most beautiful sights in the universe, filled with every color you can imagine.

They are also an extremely efficient and huge stellar factory. Countless interstellar dust gathers into stars, and the ultraviolet light emitted by young stars ionizes the interstellar dust, so they appear slightly red in the visible light band.

So the starry sky here is not dark, but colorful. Here, you can see a magical phenomenon. Bright young stars are embedded in the colorful sky, like bright gems, very beautiful.

But within the beauty lies danger. Because of the large concentration of young stars, radiation levels here are dozens of times higher than elsewhere in the universe. Moreover, the more massive the star, the shorter its age. The shortest-lived giant star even has a life span of less than 10 million years.

After a star dies, it will have different destinations depending on its mass. Stars with a mass similar to the sun will turn into white dwarfs after death. After a supernova explosion, the remaining core mass becomes a black hole or neutron star.

The material they throw out will spread over tens of billions of light-years in the form of nebulae. Over time, this material will turn into new stars.

Therefore, behind this extremely beautiful colorful sky, there are not only dotted stars, but also more than one neutron star, white dwarf and other stars, and even the most dangerous star in the universe - a black hole.

But these are nothing to Lu Yu. He used to come and go freely in the central black hole. The armor of the Silver Star has no celestial body that can threaten it in such a cosmic environment!

"This nebula is so beautiful!"

"Is there such a nebula in the Milky Way? Can this be regarded as one of the eye-catching marks?"

Lu Yu sighed and quickly looked at No. 7.

Because of the obscuration of the nebula, the stars outside the nebula appear extremely dim, even invisible. To this end, No. 7 uses a variety of observation methods, including visible light band, X-ray band, infrared, ultraviolet band and other observation methods.

However, compared with the neutrino detectors, gravitational wave detectors and other instruments installed in the previous Rubik's Cube, the power of these later detection instruments built using the technology mastered by Lu Yu has actually dropped a lot.

But as long as it can be used now, the worst possible outcome is that I will go back and dismantle the instruments of the giant spacecraft in the future!

Using the nebula in front of us as a reference, judging from the captured data, the scale of this nameless colorful nebula is definitely not less than three hundred light years.

There are also many nebulae that have been observed by humans in the Milky Way. The Orion Nebula, the Dumbbell Nebula in the Vulpecula, the Trifid Nebula, the Lagoon Nebula, the Eagle Nebula, the Cat's Eye Nebula, etc. are all familiar to astronomical enthusiasts.

If the colorful nebula in front of him could be locked to a certain nebula in the Milky Way, then Lu Yu would not be far from returning to Earth!

"The color of the nebula depends on the chemical composition and the amount of dissociation. Since most of the interstellar gas is hydrogen that can be dissociated at relatively low energy, many emission nebulae are red. If there are more High energy can cause other elements to dissociate, so both green and blue clouds may appear. By studying the nebula's spectrum, astronomers can infer that most emission nebulae are composed of 90% hydrogen. The rest is helium, oxygen, nitrogen and other elements."

"The nebula in front of us is colorful, which means..."

"All the super quantum computers in Base Zero have been put into comparing star maps!"

"At any cost, we must find a control sample of the nebula in front of us!"

Base Zero is operating at full capacity, and now the energy that a single base can control is higher than the energy of all the countries on the Blue Star combined!

If Base Zero wants to take over the global network, it only needs to connect the base's computing power to the Internet, and it can instantly dominate the network that touches everything in human life today.

And now, this huge computing power is running at full capacity, just to find a possible star path for Lu Yu to return to Blue Star.

No. 7 is also running at full capacity. It doesn't matter to her whether she returns to Blue Star or not, but that is Lu Yu's wish, so she will do her best.

In the human database, there are actually quite a few nebula observation records, especially after the establishment of the forward base, in order to find the route of the unknown fleet in deep space, a large number of observation telescopes have been built.

If there is no bright star near the gas dust nebula, the nebula will be dark, that is, a dark nebula. Dark nebulas do not emit light or reflect light, but will absorb and scatter the light from behind it.

This type of nebula is the most difficult to observe. Even so, relying on the forward base, tens of thousands of dark nebulas have been newly discovered.

And those luminous nebulae and reflection nebulae, not to mention, there are too many of them, and Professor Mao has already named them, so he simply lets AI number them all.

And now, they are turned out one by one and scanned over and over again!

".….."

Number 7 had the strongest computing power, so she stopped silently first.

When Lu Yu saw her, he understood instantly that the galaxy in front of him might not be the Milky Way.

"Isn't it just a waste of one jump? What's the big deal?"

"We used to jump continuously for five years, and I knew at that time that it was not that easy to find the Milky Way."

"Before I met you, random space jumps made me lose my way, and the universe is so big..."

Lu Yu had already exited the virtual reality and was waiting for the result in the living area. The expected feedback now made him feel relieved.

Touching Number 7's white hair, Lu Yu comforted her instead.

Although he came with expectations, Lu Yu also understood that the universe was so big that it was not that easy to return to the Milky Way.

The feedback from Base Zero came a few hours later, and Professor Han's regretful look had already explained everything.

But after all, it was just a waste of two space jumps. Why not jump back to the folding space to mess with the huge spaceship and the Zerg?

As Lu Yu thought about this, No. 7, who had already been comforted but still leaned on his arms, suddenly projected a holographic projection in front of him.

It was a neutron star that was constantly emitting periodic electromagnetic pulse signals. It had a resounding name - pulsar!

The location of this pulsar was outside the colorful nebula, but its strong electromagnetic pulse signal was still transmitted here.

This was a normal astronomical phenomenon.

But after No. 7 analyzed those periodic electromagnetic pulses, the abrupt content was revealed.

"Hello, civilization that received the message."

"Please guide us to make ice cubes, okay?"
