Zhao Dahe stood on the podium and took a deep breath; looking at the expectant eyes at the scene, he faintly felt the heavy pressure.
Exploring the satellite system will carry Dayang Group’s future hopes and determine its future development direction. This cannot be done carelessly. This may risk the entire accumulation of Dayang Group, as well as the ‘national destiny’ of the next three to fifty years, or even a hundred years.
Although it’s a bit strange for a group to say ‘national destiny’, that’s pretty much what it means.
Now the important task of exploring the satellite system falls on Zhao Dahe.
Zhao Dahe slowly inserted the mobile hard drive into the computer on the podium, and then turned on the big screen. A moment later, a hovering galaxy appeared on the large screen with a total area of 150 square meters in the conference hall.
This galaxy has four spiral arms; but the ends of the spiral arms bifurcate and begin to blur, eventually forming a fuzzy ring at the outer edge of the galaxy.
On the periphery of the galaxy, there are also sparse nebulae and "dust rings" formed by scattered small stars. The thickness of this dust ring is almost a quarter of the diameter of the main body of the galaxy, surrounding the entire galaxy like a protective ring.
If the galaxy is flat, this dust ring will be basically spherical, "protecting" the entire galaxy.
Not far away from the periphery of the galaxy, outside the "dust circle", there are more than a dozen relatively conspicuous small galaxies or star clusters, and there are also many scattered light spots.
In fact, there are many star clusters in the 'dust circle', but they are too small.
Seeing this star map, everyone's eyes seemed to be brighter.
Zhao Dahe spoke: "What you see now is the picture of the Zhoutian Galaxy, which is the latest. Of course, although it is the latest, we cannot be completely sure that our Zhoutian Galaxy has this shape.
We are inside the surrounding galaxies, and it is not easy to understand the true shape of the surrounding galaxies. Therefore, many of them are deduced through computers.
We also used pictures taken from Tianyao World, but because the distance was too far and it was impossible to deploy a large astronomical observation system in Tianyao World, the pictures taken were blurry. Moreover, the pictures we took from Tianyao World were from the side.
Picture, not front view.
After constant revisions in the later period, we finally got the picture we have now.
To put it very bluntly, one-third of the area here is directly generated by the computer, rather than a real picture. We have not observed the detailed content of the location on the back of the core of the galaxy so far.
Let me first give a brief overview of the big galaxy next week.
The data we have detected so far is that the diameter of the large galaxies in the sky is about 160,000 to 200,000 light-years, and the overall diameter is flat.
If calculated based on the gravitational range of the surrounding galaxies, the maximum range is 20 light-years in diameter. Beyond this range, stars will break away from gravity and drift among the stars.
Just like the planet's atmosphere has an exosphere, this can also be regarded as the exosphere of the galaxy.
If this calculation is followed, the thickness of the large galaxies in the sky is about 30,000 light-years.
The outer edge of this exosphere is what everyone sees as the 'dust circle'. Here, satellite systems and large galaxies compete for each other's stars, interstellar dust, etc.
Another calculation method is to calculate according to the maximum range of the spiral arm. According to this calculation, the diameter is 160,000 light-years. According to this calculation, the thickness of the galaxy is about 7,000 light-years.
In addition, in the Zhoutian Galaxy, the area covered by the "Zhoutian Array" should be about 80,000 light-years. The range of Miyuan, which is the core part of the Zhoutian Galaxy, is about just over 20,000 light-years.
Miyuan looks really small, accounting for only 6.3% of the total volume of the entire galaxy, but its mass is 40% of the entire galaxy!"
Zhang Hao asked: "What are the meanings of the two calculation methods?"
"The first calculation method is in an academic sense and is beneficial to our understanding of the universe. The second method is in a practical sense. In practical applications, just follow the second calculation method."
Zhang Hao nodded.
Zhao Dahe continued: "Now let's talk about the focus of this discussion, the satellite system.
At present, we have discovered large and small satellite systems, star clusters, etc. around the galaxy. There are 12 in total that are qualified to be recorded separately. We rank them in order of discovery.
However, although they are qualified to record and observe independently, not all satellite systems, or star clusters, have the potential to develop into new bases of the Ocean Group. For example, the No. 12 star cluster we recently discovered can only be called a star cluster.
Cluster 12 covers an area of about 30 light-years, but has less than 400 stars, most of which are small stars, mainly red dwarfs. This cluster does not even have its own black hole. There is only a red giant star in its center.
The star is small and there are not many planets. Basic supplies are severely lacking.
Therefore, after preliminary screening and rigorous discussions, the astronomical research department has selected three satellite systems: 1, 2, and 5. Today we will have a final discussion on the three satellite systems. Let me briefly introduce these three satellite systems.
A satellite system."
"No. 1, we named it the 'Pisces Nebula', using 'nebula' to distinguish it from large galaxies.
The Pisces Nebula is a complete small galaxy, and it is also the second largest galaxy we have discovered. Our preliminary research suggests that it is a complete independent galaxy that was attracted by the large galaxy around the sky.
The Pisces Nebula is currently falling towards the large galaxy at a speed of 117 kilometers per second. It is expected that in 1.2 billion years, it will be completely captured by the large galaxy around the sky and integrated into the large galaxy around the sky. Of course, we can ignore such a long time.
The Pisces Nebula has two spiral arms and looks like a Pisces playing with a bead; its core, the "bead" of the "Pisces playing with a bead", is a massive black hole, which is initially estimated to be 1.3 million times the size of the Tianyuan star.
The Pisces Nebula is about 7,600 light-years in diameter and contains about 27 billion stars. It is about 155,000 light-years away from the core of the Tianyuan Galaxy and about 165,000 light-years away from us. Due to interstellar motion, the distance to Tianyuan Star is 100,000 light-years per second.
Nearly 22 kilometers.
The Pisces Nebula has the greatest potential for development."
"On the 2nd, we named it the 'Oasis Nebula'. The Oasis Nebula is a chaotic mass with dense nebulae, and we even observed star formation in the nebula.
However, the density of stars in the Oasis Nebula is extremely high; the reason why it is named 'Oasis Nebula' is also because of the high energy density here, and the overall luster appears green under the telescope. According to the energy level, it is much higher than the red and yellow levels.
Energy levels are the rainbow colors of red, orange, yellow, green, blue, and purple. We use this to mark the energy distribution of the universe.
We speculate that the Oasis Nebula should be half of the galaxy that was swallowed up by the Great Circular Galaxy. The Great Circular Galaxy swallowed up its periphery, leaving behind a core of the galaxy.
The Oasis Nebula has a diameter of 3,700 light-years, but the mass of its core black hole is estimated to be 2.2 million times that of the Tianyuan Star. The number of stars in the Oasis Nebula is estimated to be 15 billion. However, because the nebula is relatively dense, it cannot be seen clearly.
Compared with the Pisces Nebula, it seems to have more development potential here. But it is a little farther away from us.
The Oasis Nebula is about 170,000 light-years away from the core of the Celestial Galaxy and 157,000 light-years away from us. Due to interstellar motion, the distance from Tianyuan Star is 27 kilometers per second.
The Oasis Nebula has a stable orbit and has formed a perfect balance with the surrounding galaxies."
"Then there is No. 5, which we named the 'Carp Nebula'. This satellite system is in the front, equivalent to the position of the fish's head. It is a relatively standard vortex system, but there is no distinction between spiral arms.
But it drags a long tail, like a comet. In fact, the Carp Nebula is being torn apart and swallowed by the large galaxy around the sky.
Among the three choices, the Carp Nebula is the smallest, with a main body diameter of only 2,400 light-years, and an estimated number of stars around 5 billion. Its core black hole is estimated to be about 900,000 times the size of Tianyuan Star.
The Carp Nebula is the closest to the core of the Celestial Galaxy, only 120,000 light-years away; the distance to Tianyuan Star is less than 80,000 light-years. It seems to be the easiest satellite system to reach.
Due to interstellar motion, Tianyuan Star is 'catching up' with the Carp Nebula, approaching 31 kilometers per second.
However, in order to reach the Carp Nebula, you need to pass through the Tianshe constellation, which is the location of the Red River Civilization and the military's separatist regime.
Based on the relationship between the Tianyuan constellation and the gravitational string, we may need to borrow the gravitational string of the Tianshe constellation. The Tianshe constellation is also an elongated constellation, so it should be easy to find the gravitational string.
That’s a brief introduction. If you have anything you want to ask, just ask.”
After Zhao Dahe finished the introduction, everyone became lively. Bai Yutang was the first to speak: "I have a question. 12 satellite systems or star clusters have been discovered so far. Can you briefly introduce the rest? Why are these three selected in the primary election?
?
I remember that there seems to be a ‘Satellite System No. 4’ named ‘The Straw Hat Nebula’. It seems to have a diameter of more than 12,000 light-years and is the largest satellite system discovered. Why was it not included in the selection?”
Zhao Dahe smiled and pointed to the star map on the screen behind him, "The Straw Hat Nebula is here, located on the back of the galaxy. It is 190,000 light-years away from the core of the Zhoutian Galaxy, but it is 260,000 light-years away from us.
In the middle, we need to cross the core of the large galaxy around the sky. It is unrealistic to reach the Straw Hat Nebula.
Besides, the Pisces Nebula is already big enough.
Several other satellite systems or star clusters also have similar problems, or the star clusters are too small or too far away."
As he spoke, Zhao Dahe introduced the remaining satellite systems and star clusters one by one. Most of them were like the No. 12 star cluster. The researchers were too lazy to name them and just gave them numbers.
After the explanation, everyone has to agree that the three satellite systems 1, 2, and 5 have the most potential among them.
But which one is more specific requires everyone to discuss it carefully.
One thing is very clear to the top management of Dayang Group: with the current technical situation and foundation of Dayang Group, it can only organize a fleet to explore one galaxy. It will take up to thirty years to go back and forth. A slight delay
One click, that's fifty years. This still takes into account the speed of the gravitational string.
Such a fleet must have the ability to develop and build galaxies, rather than simply sending three or five spaceships around. Preliminary estimates suggest that at least 3,000 spaceships must be dispatched.
But now the Blue Star Group is facing a war, and various resources are beginning to be stretched; in another thirty to fifty years, a war may break out at the World Gate in the rear at any time, and it will be a war between two worlds.
Therefore, if you think about it casually, you can understand that the Ocean Group's opportunity to explore the satellite system will only have one opportunity within the foreseeable century!
Once it fails the first time, there will be many difficulties in the follow-up. Especially it is unknown whether the other members of the Blue Star Group have other ideas.
And judging from the current development speed of Dayang Group, in another thirty years, Dayang Group's development space will reach its limit. Dayang Group urgently needs a territory that belongs entirely to itself!
The entire Dayang Group has been under tremendous pressure, but even if the pressure is doubled, it still has to bear the burden and move forward. The huge pressure to survive makes Dayang Group not only unable to slow down, but also to continue to accelerate.
In order to relieve the pressure within the group, other methods must be adopted. For example, marriage can be used to create happiness. Or exploring outer space can allow the pressure within the group to vent.
In short, under this premise, the senior management of Dayang Group started a discussion on the current three satellite systems. But gradually, everyone focused on the No. 1 satellite system and the No. 2 satellite system. However, during this process, Bai Yutang
Never spoke.
Satellite System No. 1, the Pisces Nebula, seems to have the most potential, but it is a bit far away; it is 165,000 light-years away from Tianyuan Star.
The No. 2 satellite system, which is the Oasis Nebula, has great potential and is much closer. The distance from the Tianyuan Star is 157,000 light-years; but the distance between this galaxy and the Tianyuan Star is widening, at a rate of 27 seconds per second.
kilometers, then 850 to 860 million kilometers can be covered in a year.
This distance... may be negligible. Today's spacecraft often travel thousands of light-years and hundreds of millions of kilometers per month. Even if calculated at 860 million kilometers per year, it would take about 11,000 years to open a light-year distance.
It’s not that easy to choose the Oasis Nebula because there are thick nebulae in the Oasis Nebula!
You can imagine how the industrial development and life of such a planet will be affected if a planet is covered with heavy fog all year round. This is the situation of the Oasis Nebula.
In addition, according to astronomical telescope observations and occultation observations, it is suspected that there are a large number of very large starry sky beasts in the Oasis Nebula.
Regarding this, Zhao Dahe focused on explaining: "The so-called occultation observation is very simple. If a person walks in front of the light, it will cover the light, causing the light to be dim. Similarly, if a planet passes in front of the star, it will also be partially obscured due to
The star's light changes slightly.
This change may be one in 10,000 or one in 100,000, but through a high-precision telescope matrix we can detect faint changes 100,000 light-years away.
The Oasis Nebula is a bit far away, but after technical adjustments, we can barely observe some peripheral occultations of blue giant stars. But we found that the stars here change rapidly and irregularly. Whether it is frequency, or the intensity of the obscured light, etc.
At first we thought it was a spaceship, but we quickly ruled it out because the routes of spaceships are generally relatively stable.
Everyone should know that the spacecraft travels very fast in the starry sky, and the route of the spacecraft is fixed for safety. Even the small countries in Zhoutian World will have such arrangements.
Finally, after comprehensive consideration and referring to the opinions of the staff, we believe that it is a starry sky beast. And in the entire Oasis Nebula, there are probably not a few such starry sky beasts. These starry sky beasts that have been developing freely for countless years may not be what we can now
To deal with.
After all, we have speculated that the Oasis Nebula is likely to be the remaining core of a large galaxy. The original size of this large galaxy is estimated to be one-quarter to one-third the size of the current large galaxy. Such a place gave birth to behemoths in the starry sky.
, completely understandable.”
After hearing this, Zhang Hao couldn't help but ask: "How long have you been observing this situation? How confident are you?"
"We have been observing this phenomenon for half a year, and we have used almost all telescopes to form a super array for observation.
This super array telescope forms a super telescope with a virtual diameter of 120,000 kilometers, and the observation accuracy... should be above 90%."
Virtual telescope is a telescope technology of Dayang Group. By arranging a large number of telescopes into an array, all the telescopes are linked through computers to form a bee-eye-like structure. However, this bee-eye is a bit large and can reach 12
Thousands of kilometers.
Through this kind of technology, the current telescope technology of Dayang Group can be brought into full play, and the sensitivity of a single telescope can be one million times higher. Of course, the cost has also increased.
But through such telescope technology, Ocean Group has also benefited a lot.
Zhang Hao pondered a little. From the current point of view, the Oasis Nebula is undoubtedly the most suitable. But if there are really a large number of starry beasts here, it will be another matter.
After pondering for a while, Zhang Hao suddenly said, "Is it possible to do this? We can send a fleet to the Pisces Nebula, but take a detour in the middle and pass by the Oasis Nebula."
"I'm afraid this won't work. The two nebulae are far apart."
Zhang Hao added: "What if we just try to get as close as possible to the Oasis Nebula and observe it up close?"
Zhao Dahe pondered for a while, looked at the star map, and said: "If you want to not affect the trip to the Pisces Nebula, you can get closer to 50,000 light-years at most. Then you have to turn around and head to the Pisces Nebula.
But if we could travel 50,000 light years, our observations might be twice as clear."
But at this time, Bai Yutang, who had been silent, spoke up, "I think it might be better to explore the Carp Nebula."
"Oh?" Everyone focused their attention on Bai Yutang.
But Bai Yutang stood up, walked to the podium, and walked to the star chart. He ran his fingers across the Tianshe constellation and said, "Everyone, the Tianshe constellation is basically independent for the time being. It is no longer controlled by the royal family of the Red River Empire, nor is it controlled by the royal family of the Red River Empire.
It was then controlled by the Yujing Empire. There was even intelligence indicating that the Tianshe Constellation was colluding with the 'Tianji Empire'.
The Tianji Empire is located to the east of the Yujing Empire. These interstellar powers have been feuding for tens of thousands of years.
But now that the Blue Star Group is facing a war, the Yujing Empire may not be able to take care of this. Then we may have the opportunity to purchase the Tianshe Constellation from the Yujing Empire and the Tianshe Constellation from the royal family of the Red River Empire.
The Tianshe constellation is almost located on the edge of the Zhoutian Galaxy and the Zhoutian Formation, which is of little significance to the Yujing Empire. The Red River Empire is also beyond its reach. So I think both the Yujing Empire and the Honghe Empire will agree.
The Tianshe Constellation is just a separatist regime of the Red River Civilization and the military, but such a separatist regime is not popular among the people. Moreover, the Tianshe Constellation has been developed for a short time and has almost no foundation. After we obtain the nominal ownership, we can completely occupy this place with force!"
"There is one more important thing." Bai Yutang said, running his fingers across the Tianshe constellation, "The Tianshe constellation is long and slender. Let's see if it looks like a guide rail, a gravitational string guide rail. If we can include the Tianshe constellation into our
Within the sphere of influence, we can use the gravitational strings of the Tianshe constellation to 'launch' the fleet and reach the Carp Nebula faster.
As for the problem that the Carp Nebula is too small, you don’t need to worry about it in the short term. It is enough to support the recent needs of Ocean Group.”
Bai Yutang's suggestion aroused great interest in everyone in an instant. Yes, Dayang Group and Tianyuan Star Civilization have now grown into overlords, and they no longer need to be as cautious as in the past.
Previously, Gautama also obtained the small star cluster "Jinghui 16 Stars" from the royal family and completed its occupation. So now it seems that it is nothing to get involved in the Tianshe constellation.
Another very important point, which everyone has actually discussed before, is the fuel of the spacecraft. The nuclear fuel of the current spacecraft can travel up to tens of thousands of light-years at a time. If you want to cross the starry sky of 100,000 light-years, even if you add storage space technology
, fuel must be replenished at least twice in between.
If you want to go to the satellite system, you must consider the issue of supply stations. Therefore, the meaning of the Tianshe constellation has virtually added another layer.
(A big chapter of 5,500 words. I haven’t felt this good in a long time. I won’t separate.)
