What kind of miracles will there be in space? What dangers might there be? Based on current human cognition, it is still too little. Not to mention anything else, a nebula can easily span more than ten light-years, and it is no small matter to explore it all.
For now, this dark nebula is enough to give humans a headache. Forget about ordinary nebulae, at least they are dominated by gas and supplemented by dust. But here it is just reversed, dominated by dust fragments and supplemented by gas. In addition, there is no star illumination here, etc., this area is really out of reach. Five fingers, making this place even more dangerous! There was so much debris that the spacecraft could not move forward at full speed. Of course, it is still possible to go around it with current technology; but one of the goals of human exploration this time is this dark nebula. Running all the way 1,200 light years away, the dark nebula right now is one of the targets.
"There is no light, making exploration very troublesome!" Zhao Qingyun frowned, the universe is challenging human cognition every moment. In the past, to explore the universe, we only needed to capture the light, because the light would carry enough information. But now there are no natural luminous objects, so you can only see them bit by bit, which is very difficult.
If there is a light source, we can observe the situation in extremely distant places years or decades in advance; but without light, we can only emit light or detect waves by ourselves, and then study based on the feedback. This time, I don't know how much time is wasted.
And because there is no light in this place, there is very little radiation of all kinds, as if this place is a dead place! It feels like this place is like a scar in the universe!
There is no light and little radiation. If you want to explore, you can only launch detectors personally and in large quantities. In order to make up for this lack of time, some unmanned spacecraft carry a large number of detectors to shuttle around every corner. The complex cosmic environment makes small detectors extremely short-lived - only a few days, making it difficult to complete effective exploration.
And even some defensive detectors can hardly maintain their lifespan for a month when washed away from such a distance.
Such consumption, whether it was a waste of time or resources, made Zhao Qingyun frown a little.
Zhao Qingyun suddenly stamped his feet anxiously. He had never encountered such a cosmic environment. It’s simply a starry sky of death! "Three years! We can stay here for three years at most! If we haven't gained anything after three years, we will give up temporarily and explore more on the way back.
The civilization in front may still be waiting for our rescue. If possible, we cannot sit back and watch intelligent life be ruled by iron lumps! ”
It’s just that the wisdom of the universe is not yet within the reach of human beings today. Very natural. It is difficult to obtain satisfactory results for the time being. Time passes day by day.
Some places that have been explored are constantly being improved. A dead world slowly unfolded in front of everyone. With the launch of more large-scale, protected detectors and unmanned spacecraft exploration, finally, there is good news!
Found a slightly broken planet. The density of the planet actually reaches more than 8 million standard density (water density).
"The density of more than 8 million is far less than the density of neutron stars and less than the density of white dwarfs. So, it is a black dwarf!!! And it cannot self-circle after being broken. It is obviously not that the gravity is not enough, but that the material it is composed of is strong enough!" Zhao Qingyun blinked. It’s bright! Black dwarfs are definitely one of the most difficult to detect celestial bodies in the world, because they do not emit any heat or light, or in other words, they are one of the last remnants of stars. They are really remnants, ashes-level remnants! It does not emit heat or radiation, and its range of influence is extremely small. Compared with the influence range of stars, which can easily reach hundreds of billions of kilometers or even several light-years, its influence is only within a hundred billion kilometers! Such a scope of influence really makes exploration more difficult!
With a little exploration, gradually more results started to appear.
A year later, the general situation of the nebula within a radius of ten light years was explored. In the end, Zhao Qingyun and others came to a conclusion based on the exploration: This place turned out to be a celestial body cemetery! Of course, this is a description, but the situation here is really the same. There is not a single star in the entire dark nebula!
"Let's go and have a look. It would be a pity not to see the cemetery of stars when we arrive in the universe." Zhao Qingyun made a prompt decision, and he and Sun Feiyu called a complete exploration team and set off. The group of people took an exploration spacecraft that was only five kilometers in size and set off directly to the location of the black dwarf they had just discovered.
A scientist named Li Jia next to him is leading a scientific team to analyze various aspects of data, and is even adjusting some previous theoretical research. Of course, everyone is very excited. Being able to explore a brand new celestial body is definitely a huge gain, at least in terms of reputation! In today's Chinese civilization, reputation, morality, etc. are already one of the most important indicators that affect a person's evaluation.
Among them, scientific honors are among the best, because scientific achievements are also the easiest to judge a person's contribution to this civilization.
Black dwarfs, this celestial body that has always been theorized, cannot be directly observed and can only be observed indirectly; but unfortunately, they have not been discovered so far. Now, there is likely to be a black dwarf ahead, and even Zhao Qingyun is a little happy.
A group of people is simply not exploring the nebula, but traveling. Maybe this is the travel companion of the interstellar era.
The spacecraft is not moving very fast. It only maintains 0.7 times the speed of light. It will move forward in space only when it is sure to be safe enough. After all, this place is full of dangers. If the spacecraft accidentally hits that kind of hard debris, The consequences are unpredictable! If we plunge into the black dwarf, everyone will be able to smile. Even the Immortals have no ability to gain a foothold in the Black Dwarf - no one has tried, and no one dares to try! These extreme things are monuments that challenge mankind!
"Beep beep beep..." Suddenly an urgent alarm sound sounded, which turned out to be the highest level.
In an instant, Li Jia retrieved all the data, but the spacecraft still maintained a state of advancing at 0.7 times the speed of light. Sometimes in space, when encountering danger, it is best not to panic unless you have received precise information. Now, what Li Jia needs to do is to judge the danger.
"Unmanned spacecraft No. 176 has detected that two black dwarf galaxies are approaching each other nearby. Affected by changes in distance and gravity, the speed is rising in a curve and accelerating. This is the affected range of the surrounding area.
< br>
Unfortunately, one of the black dwarf galaxies is the one we are about to explore. ”
Zhao Qingyun and others saw the projection created by the scientists.
Li Jia: "There is no way to clearly explore the specific conditions of the two black dwarf galaxies; we can only roughly detect a dangerous range based on gravity and other conditions. A large number of small detectors have been launched, but we still need to get specific information. some time.
Based on the current situation, we need to temporarily stop moving forward. However, I personally think that unmanned spacecraft should be quickly launched to detect the collision of two galaxies; we have never encountered such a situation, and it is very worthy of study. ”
"Two black dwarfs collide? Yes, it's worth watching!" Zhao Qingyun's eyes flashed with excitement, "Li Jia, do you think that if two black dwarfs collide, do we have a chance to collect fragments of the black dwarfs?"
Um? Li Jia was stunned for a moment, and then he was ecstatic! Yes, if you can collect the fragments of the black dwarf, it will definitely be a huge harvest. Among all the celestial bodies that are related to stars, it goes without saying that normal stars are simply gaseous, and there is no such thing as debris. As for ordinary neutron stars, the surface is a slurry flow, and it is difficult to produce fragments; and the mass of a neutron star 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, forget it. Now humans can only circle around a black hole 1 billion kilometers away at most.
Then, to study massive celestial bodies, this type of black dwarf is undoubtedly the best choice. But black dwarfs are not easy to find, and humans are not very clear about the shape of black dwarfs. But isn’t there an opportunity now? And based on the gaps on the black dwarf, we can know that the black dwarf is solid, and it is an extremely hard solid!
"Contact me the fleet behind me and send 1,000 warships over. When the two black dwarfs collide, target the black dwarfs and attack. While the two black dwarfs collide, try to collect as many fragments as possible!" Gradually, Zhao Xingyu's eyes flashed with a somewhat crazy light.
Even if ordinary neutron stars collide, their huge density and gravity are enough to allow the two neutron stars to perfectly merge together! Then only black dwarfs, which are larger in size but smaller in density and mass, are the best research objects for human research now.
"Yes!" Naturally, there was a messenger nearby conveying the order.
"Li Jia, how long until the two black dwarfs collide?"
"Your Highness, it is expected to take one year, three months, seven days and 17 hours."
Zhao Qingyun nodded, "Since there is enough time, launch a large number of one-time detectors and collect data on the surface of the black dwarf by directly hitting the surface of the planet. Note that not only active detectors with their own light sources must be launched, but also active detectors with their own light sources must be launched. That kind of passive detector. Let's see what kind of radiation such an object would have.
Also, if the black dwarf itself does not emit any photothermal radiation, it will be a good opportunity to study the relationship between mass and space. Therefore, space and other related detectors should not be forgotten.
Use several unmanned spacecraft to directly send the detectors and others to the front to start exploration.
Unexpectedly, there would be such a surprise this time. Black dwarfs must detect enough data.
By the way, you directly contact the rear to dispatch a scientific research ship. ”
"Yes!" Li Jia was also excited. "But Your Highness, we are a little close now and need to move a little distance."
"Then move. You have the final say on scientific matters, I won't interfere. I only want the final result." This means that Zhao Qingyun completely let go of the rest of the scientific investigation and other matters, letting them explore . Let professionals do professional things! This is the current social climate. After a series of orders were issued, Zhao Qingyun became completely idle, waiting for the final result. (To be continued...)
