What kind of miracles will exist in space? What kind of dangers will exist? According to the current human cognition, there are still too few. In addition, a nebula is often more than ten light years, and it is not a small matter to explore it.

At present, this dark nebula is enough to give humans a headache. For ordinary nebula, it is not enough, at least it is mainly gas and dust as the supplement; and here just turned upside down, with dust fragments as the main one, gas as the supplement; plus there is no star lighting here, etc., this area is really invisible to see its five fingers, making it even more dangerous! There are too many fragments that the spacecraft cannot move forward at full speed. Of course, it is still possible to circumvent it with current technology; but one of the purposes of human exploration this time is this dark nebula. Running 1,200 light years from afar, the dark nebula is one of the goals.

"No light makes exploration very troublesome!" Zhao Qingyun frowned. The universe was challenging human cognition every moment. In the past, exploring the universe was just enough to capture light, because light would carry enough information. But now there are no natural luminous objects, and all of them can only be seen bit by bit by bit, which is too difficult.

If you have a light source, you can observe the situation in extremely distant places a few years or decades in advance; if you don’t have light, you can only emit light or detect waves by yourself, and then study it based on the feedback situation. This time, I don’t know how much time has been wasted.

Moreover, because there is no light in this place, there is very little radiation, as if this is a dead place! It gives people the feeling that this place is like a scar of the universe!

There is no light and little radiation. If you want to explore, you can only launch the detectors actively, and it will be a large number of launches. In order to make up for this time, some unmanned spacecraft carry a large number of detectors to shuttle through every corner. The complex cosmic environment makes the lifespan of small detectors extremely short - only a few days of life, making it difficult to complete effective exploration.

Even some defensive detectors have difficulty maintaining their lifespan for one month under such a distance.

Such consumption, whether it is a waste of time or resources, made Zhao Qingyun frown.

Zhao Qingyun suddenly stomped his feet anxiously, and had never encountered such a cosmic environment. It was simply a starry sky of death! "Three years! We stay here for at most three years! If we don't have anything to gain in three years, we will give up temporarily and explore on the way back.

The civilization ahead may still be waiting for us to rescue. When possible, we cannot sit idly by and watch our intelligent life be ruled by iron knots!”

It’s just that the wisdom of the universe is not something that humans can reach today. It’s very natural. It’s difficult to get satisfactory results for the time being. Time passes day by day.

Some places that have been explored are constantly being improved. A dead world is slowly emerging in front of everyone. With more large-scale detectors launched with protective layers and unmanned spacecraft exploration, finally, there is good news!

I discovered a slightly broken planet. The planet's density actually reached more than 8 million standard density (water density).

"The density of more than 8 million is much smaller than the density of neutron stars and also smaller than the density of white dwarfs. Then, it is a black dwarf!!! And it cannot be self-circulated after it is broken. Obviously, it is not that the gravity is insufficient, but that the material composed is strong enough!" Zhao Qingyun's eyes lit up suddenly! The black dwarf is definitely one of the most difficult celestial bodies in the world to detect, because it does not emit light and heat, or it is one of the last wreckage of the star. It is really a wreckage, a harbor! Not only does it emit light and heat without radiation, the impact range is also very small. Compared with the influence range of a star that often has hundreds of billions of kilometers or even light years, its influence is only within 100 billion kilometers! Such an impact range really increases the difficulty of exploration!

With a little exploration, more results gradually began to appear.

A year later, the general situation of the nebula within a radius of ten light years was explored. Finally, Zhao Qingyun and others came to a conclusion based on the exploration: this is actually a cemetery of celestial bodies! Of course, this is a description, but the situation here is really the case. There is no star in the entire dark nebula range!

"Let's go and have a look. When we get to the universe, it's a pity not to look at the cemetery of the stars." Zhao Qingyun made a quick decision, called a complete exploration team with Sun Feiyu, and set off. The group took an exploration spacecraft that was only five kilometers in size and set off directly towards the black dwarf position he had just explored.

A scientist named Li Jia next to him is leading a scientific team to analyze data from all aspects, and even adjusting some previous theoretical research. Of course, everyone is very excited to be able to explore a brand new celestial body. Not to mention anything else, at least in reputation, it is definitely a huge gain! In today's Chinese civilization, reputation, morality, etc. are already one of the most important indicators that affect a person's evaluation.

In this case, scientific honors are among the best, because scientific achievements are the easiest to judge a person's contribution to this civilization.

The black dwarf, a celestial body that has always been in theory, cannot be directly observed and can only be observed through indirect observation; unfortunately, it has not been discovered so far. As it appears, there is a black dwarf ahead, and even Zhao Qingyun is a little happy.

A group of people are not exploring the nebula, but traveling. Maybe this is the hikers of the interstellar era.

The spacecraft is not moving forward quickly, only maintaining 0.7 times the speed of light. Only when it is possible to be sure that it is safe enough will it move forward. After all, there are various crises here. If the spacecraft accidentally hits the hard fragments, the consequences will be unpredictable! If it plunges into the black dwarf, everyone can "smiling in the sky". Even immortals do not have the ability to gain a foothold in the black dwarf - if they haven't tried it, no one dares to try it! These extreme things are monuments to challenge humans!

"Dududu..." Suddenly, the alarm sounded urgently, and it turned out to be the most advanced.

In an instant, Li Jia called out all the data, but the spacecraft still maintained a state of 0.7 times the speed of light. Sometimes when you encounter danger in space, you should avoid panic, unless you have obtained the exact information. Now, what Li Jia needs to do is to judge the danger.

"Unmanned spacecraft 176 detected that two black dwarf galaxies were approaching each other nearby, and were affected by distance and gravity changes, and their velocities were in a state of rising and accelerating curve. This is the range affected around them.

Unfortunately, one of the black dwarf galaxies is one of the ones we are going to explore.”

Zhao Qingyun and others saw the projection called out by scientists.

Li Jia: "The specific situation of the two black dwarf galaxies cannot be clearly explored; one can only detect a dangerous range based on gravity and other conditions. A large number of small detectors have been launched, but it will take some time to get specific information.

Based on the current situation, we need to stop moving forward temporarily. However, I personally think that we should quickly launch unmanned spacecraft and other spacecraft to detect the collision between two galaxies; we have never encountered such a situation before, and it is very worth studying."

"Two black dwarf galaxies collided? Not bad, worth watching!" Zhao Qingyun's eyes flashed with excitement, "Li Jia, do you think if two black dwarfs collided, will we have the chance to collect fragments of the black dwarf?"

Hum? Li Jia was stunned for a moment, and then she was ecstatic! Yes, if you could collect fragments of black dwarfs, it would definitely be a huge harvest. Among all the celestial bodies that are related to stars, normal stars are simply gas, and there is no such thing as fragments. However, ordinary neutron stars have a slurry flow on the surface, and it is difficult to produce fragments; and the mass of neutron stars is large enough to be difficult to break; its powerful mass can even convert all attack damage into its own mass!

As for black holes, even if it is not enough, now humans can only circle around 1 billion kilometers away from black holes at most.

Then, when studying large-mass celestial bodies, this type of black dwarf is undoubtedly the best choice. However, black dwarfs are not easy to be found, and humans are not very clear about the form of black dwarfs. But there is a chance at the moment! And based on the gaps in black dwarfs, you can know that black dwarfs are solid and extremely hard solid!

"Contact me with the fleet behind and send 1,000 warships over. When the two black dwarfs collide, aim at the black dwarfs to attack. Try to collect fragments when the two black dwarfs collide!" Gradually, a little crazy glow flashed in Zhao Xingyu's eyes.

Even if ordinary neutron stars collide, their huge density and gravity are enough to perfectly merge the two neutron stars! Then only black dwarfs with larger sizes but smaller density and mass are the best research objects for human research today.

"Yes!" There was a commissar next to him who conveyed the orders.

"Li Jia, how long will it take for two black dwarfs to collide?"

"Your Highness, it is expected to take 17 hours a year, three months, seven days and 17 hours."

Zhao Qingyun nodded, "Since there is enough time, a large number of disposable detectors are launched to collect data on the surface of the black dwarf by directly impacting the planet's surface. Be careful not only to emit active detectors with their own light sources, but also to emit passive detectors. Let's see what kind of radiation such a celestial body will have.

Also, if the black dwarf itself does not emit any light and thermal radiation, it will be an opportunity to study the relationship between quality and space. Therefore, don’t forget to detectors related to space.

Use several unmanned spacecraft to directly send the detectors, etc. to the front and explore.

Unexpectedly, there was such a surprise this time. Black dwarfs must detect enough data.

By the way, you can contact the rear directly to dispatch a scientific research ship.”

"Yes!" Li Jia was also excited. "But Your Highness, we are a little closer now and need to move a little distance."

"Then move. You have the final say in science, I won't interfere. I just want the final result." This means that Zhao Qingyun completely let go of the rest of scientific investigations and other things, and let them explore professional things. Let professionals do it! This is the current social atmosphere.
Chapter completed!
