Interstellar Industrial Age

The vast cosmic starry sky is vast and boundless. No one knows where the end of the starry sky is. Compared with it, everything seems incomparably small and insignificant.

In a dark, dark, and icy place with a trace of eternal aura, the calm air without a trace of turbulence suddenly burst into ripples, like water waves.

Soon, the ripples became bigger and bigger, and slowly a colorful light point appeared, and soon it slowly fainted, and in a blink of an eye, it became a colorful and radiant space-time channel.

From the space-time passage, a huge silhouette of a space battleship flew out rapidly, and the battleship was brightly lit, like a huge temple from the depths of the starry sky.

As the spaceship flew out, the space-time wormhole quickly and slowly shrank rapidly, disappearing in a blink of an eye, and the fluctuations in the void gradually returned to calm, as if nothing had happened, only the left This huge cosmic battleship in the dark void is like a firefly in the dark starry sky, so eye-catching.

On the 'Explorer' space battleship, the people who finished the warp flight began to become busy, and various probes were launched in all directions in order to control the surrounding void and ensure their own safety.

At the same time, the various detectors carried on the space battleship are all turned on, and they are continuously receiving various information from the void of the universe.

As a cosmic astronomy scientist, Cao Yadong is the busiest. After each warp flight, he has to re-position the spaceship, and then re-correct the coordinate parameters of the spaceship based on the received information.

The cosmic starry sky is too vast, and when it is in the void, there is no distinction between front, back, left, right, and up and down, so the spacecraft will easily get lost when it is flying at warp speed in the starry sky.

Especially as the space battleship gets farther and farther from the solar system, and as the warp engine becomes more and more powerful, it can jump farther away at one time, and the probability of getting lost will increase.

The role of cosmic astronomy scientists is equivalent to the compass on the spaceship and warship, constantly gathering the received starlight to draw a more complete and detailed star path, locating the spaceship, correcting the coordinate parameters, etc., to prevent it from being in the void of the universe lost.

"It's 88 light-years away from the solar system."

Cao Yadong and his team quickly calculated their current location. After several months of voyage, they have left the solar system a distance of 88 light-years away.

"Draw the latest star map!"

Cao Yadong's thoughts connect the virtual world,

A star map appeared in his mind. This star map was drawn by Xinghan astronomical scientists after a long period of observation, and it was also an indispensable thing in interstellar navigation.

Star maps are different from traditional geographic atlases or celestial photos. Star maps are a collection of precise descriptions or drawings of persistent features in the night sky, such as stars, constellations of stars, the Milky Way, nebulae, star clusters and other extragalactic galaxies, so it is also called "Map of the Stars".

Traditional maps are mapped according to geographical features, such as rivers, mountains, lakes, etc. are important reference objects on traditional maps.

Of course, relying on modern scientific and technological means, drawing traditional maps can be very accurate, but in ancient times, drawing maps required important symbolic things.

The same is true for a star map. A star map is a map of stars in popular terms, which includes all the stars that scientists can observe, and uses some stars to draw a star map.

Some people may say that the stars all look exactly the same, and there is no difference at all. Anyone relying on the stars to identify directions, perform positioning and navigation, etc.?

In fact, the stars in the sky, each star is completely different.

A star is a star, a neutron star, a comet, a white dwarf, and other celestial bodies in the universe. The distance, mass, and intensity of these celestial bodies are completely different.

Stars that look exactly the same to our naked eyes and seem to have no difference are completely different to the eyes of cosmic astronomy scientists, and it is even difficult to find two identical stars.

The composition of the star map takes advantage of this.

Because each star is different, scientists can use these stars to navigate, locate, and calculate their detailed location.

This is a star map, a map of stars.

Of course, in the star map constructed by stars, the only things that can be used as pointers are the neutron stars and pulsars in the universe.

Neutron stars are the densest stars in the universe other than black holes. They are also evolved from stars. Most pulsars are neutron stars, but neutron stars are not necessarily pulsars. Only those with pulses are considered pulsars.

Because neutron stars have high mass and high density, neutron stars have many very special characteristics. One of them is that some neutron stars have pulse characteristics. This pulsar is the brightest child in the universe and the easiest target to find. , which is naturally equivalent to the mountains, rivers, etc. in traditional maps, which are very important coordinate reference objects.

In addition, the energy radiation of neutron stars is millions of times that of the sun. Such a huge energy radiation is like a lighthouse in the vast void. It is very dazzling, and cosmic astronomy scientists can know it at a glance.

Therefore, in a star map, the most important are neutron stars and pulsars, because these two kinds of stars are the lighthouses in the universe, the reference objects, and the brightest ones.

As for other stars, or stellar clouds or constellations, etc., with the movement of the position, it is very likely that it is difficult to observe, or there will be some changes, which are more difficult to find. not very accurate.

Xinghan's cosmic and astronomical science has been observed and recorded for a long time. It has been observed in many planetary systems of Xinghan, and it has also drawn a huge and vast star containing trillions of stars, thousands of neutron stars, and pulsars. picture.

Relying on this star map, the 'Explorer' spacecraft will not get lost in the starry sky when flying in the void of the universe, and can always find its way home.

"A brand new neutron star was discovered, located in the central region of the Milky Way, about 7,230 light-years away from us."

Every time cosmic astronomy scientists go to a new place, the first thing they do is observe the starry sky where they are located, collect the information of the stars in the starry sky, and then combine it with the existing huge star map, so as to carry out the star map. Continuous improvement.

"The sun is now just a little faint star."

Cao Yadong looked in the direction of the solar system. The sun is the most ordinary boy in the universe. It neither shines nor flashes. It is very ordinary, and there is nothing special about it.

When looking at the solar system from a distance of 88 light-years from the solar system, the light of the sun is very weak, very weak, and even requires the help of a cosmic astronomical telescope to observe the existence of the sun.

"The more you fly in the direction of the Milky Way, the denser the star will be. As expected, most of the matter in the Milky Way is concentrated in the central area of ​​the Milky Way. I really want to go to the Milky Way. Take a look at the center, the stars here should be extremely bright and dazzling, and it is estimated that the distance between stars may be only a few dozen astronomical units."

Cao Yadong carefully looked at the various information he received. He also kept observing all the way, and gradually discovered a pattern.

The closer this is to the center of the Milky Way, the denser the stars, which also confirms an inference that scientists have long been in, because of the huge attraction of the black hole at the Milky Way's core.

Most of the matter in the Milky Way is concentrated in the central area of ​​the Milky Way. As for the banking system cantilever such as the Orion Cantilever where the solar system is located, the proportion of matter is very small.

Therefore, scientists have also made a lot of reasonable inferences and conjectures, and now they have verified this inference. The more you fly in the direction of the Milky Way, the greater the density of observed stars.

"According to inference, there is not only a black hole in the center of the Milky Way in the Milky Way. The Milky Way is so huge, but it is very stable. In addition to the core black hole, there should also be small black holes on the cantilever of the Milky Way."

"The black hole at the center of the Milky Way dominates the entire Milky Way, and the small black holes play a role in stabilizing the Milky Way, but so far we have not found the existence of black holes on the Orion Cantilever. Is this inference wrong?"

Soon, Cao Yadong also remembered a conclusion calculated and deduced by the scientific community of Xinghan cosmic astronomical science community using super quantum computer.

Based on a large number of observations, scientists infer that there are more than one black hole in the Milky Way, and the black hole at the center of the Milky Way is a massive black hole that dominates the entire Milky Way.

In addition to the large black hole in the middle, there are also small black holes in the cantilever of the Milky Way and the outer satellite galaxies of the Milky Way, such as the Large and Small Magellanic Clouds.

It is under the joint control and efforts of these black holes, large and small, that the entire galaxy can operate stably, forming a huge galaxy.

This time, the spacecraft that went out to explore is actually taking into account the purpose of scientific research. For cosmic astronomical scientists, one of their important tasks is to find the small black hole above the Orion cantilever to verify scientists' inferences about the Milky Way.
