Yes, as early as nearly a hundred years ago, as early as when he was still in the ruins, Zhao Changxing made up his mind to build a new neutrino telescope to collect as many remnants of the ruins civilization left here as possible, and as much as possible When he obtained those gravity bombs, Zhao Changxing anticipated the day when energy would be insufficient.
The difference lies only in the degree of energy deficiency.
Is it a serious deficiency, so much so that the Yuan Voyage spacecraft has no antimatter energy available and cannot even maintain its life support system? Or is it slightly insufficient, so that although life is difficult, it can still barely survive?
It depends on luck. To put it more intuitively, it is the failure rate of the Yuanhang spacecraft.
Because the higher the failure rate, more people need to wake up from hibernation, and more materials and energy are consumed.
Taken together, the energy shortage level at this stage is not too high, that is, the luck is pretty good.
Facing Xiaoxi's report, Zhao Changxing nodded gently.
"This day is bound to come. Since it has already come, then... stop slowing down. We cannot watch people die of thirst and starvation."
Following Zhao Changxing's order, the blazing tail flames with a total ejection area of ten square kilometers at the tail of the Yuanhang spacecraft slowly reduced its brightness to less than one-tenth of its original level.
This means that its propulsion power is also reduced to a corresponding level.
Although calculated according to this deceleration rate, there is no doubt that the Yuanhang spacecraft cannot stay in the Lakai 9352 galaxy.
In this way, a large amount of antimatter energy is saved and diverted to more critical life-support consumption and troubleshooting consumption.
Before this, many sealed nuclear fusion reactors had been activated and began to supply energy to the outside world.
Compared with the annihilation of matter and antimatter, nuclear fusion is undoubtedly a less efficient way to obtain energy. In normal navigation, people obviously don't think about it, and they don't deliberately reserve fusion fuel.
With all that payload space, it’s better to store more antimatter.
But now, there is really no other way. We can only divert some water under the premise of strictly limiting people's water consumption, electrolyze hydrogen and use it for fusion.
Time slipped away quietly under such circumstances. The star in the distance is getting brighter and brighter.
At this moment, the Yuanxian spacecraft has successfully crossed the boundary of the star, which is the Oort cloud zone. According to theoretical calculations, the total amount of matter in its Oort cloud is approximately equivalent to ten Earths.
This is undoubtedly a lot of matter. Unfortunately, the Yuanxian spacecraft did not find any macroscopic matter during its passage through the Oort cloud.
Only precision equipment can tell people the data about the rapid increase in the density of matter, which can allow people to more intuitively feel that the distance to the star is getting closer.
This can already be regarded as the area near the star. At this moment, the space outside the Yuanhang spacecraft can still be regarded as an extremely pure vacuum, but the average number of particles per cubic centimeter in the space has reached tens of thousands.
If the ruins were located here, then trying to find those gravity bombs by detecting muons with a neutrino telescope would no longer work.
The slow journey that has lasted for hundreds of years is almost coming to an end - if people can slow down the Voyage spacecraft enough to be captured by the gravity of the planet here.
The Yuan Voyage spacecraft is almost out of fuel at this moment. At this moment, the pressure on all awake people has reached the limit. Their minds and bodies have also reached their limits. They may collapse at any time. Now, they cannot stay in a galaxy with abundant supplies. Among them, it undoubtedly means the demise of civilization.
Zhao Changxing and civilization leaders both know this. This is clear to everyone at this moment. But at this moment, the Yuanhang spacecraft still maintains an extremely low deceleration rate and still does not increase power.
When the brightness of the star increased to several times brighter than Venus, the Voyage spacecraft passed through the material structure of this galaxy similar to the Kuiper Belt of the solar system at a speed of nearly a thousand kilometers per second, and then headed straight Rushing towards the huge star in the center of the galaxy.
There are also many asteroids and comets in this galaxy.
Because the three large planets inside fought with the gravitational pull of the star itself, they were gradually expelled to the edge of the galaxy, where they gathered, eventually forming a structure similar to the Kuiper Belt.
Among them, there are at least 100,000 stars with a mass of more than 10,000 tons.
But unfortunately, the density of this material is still too low. The Yuan Voyage spacecraft passed through it without any disturbance and did not obtain any supplies from it.
During this process, the space shuttle, which was located 100,000 kilometers away from the Yuanhang spacecraft and had been towed by the Yuanhang spacecraft, broke free from the shackles of the cable.
It started to decelerate and turn on its own at a higher acceleration than the Yuanhang spacecraft, and began to fly towards Planet 3.
Even if the energy is insufficient, people can still put such a small spacecraft into orbit.
After crossing the Kuiper Belt, or the asteroid belt or the comet belt, it all means the same thing. After that, the Voyage spacecraft continued to move forward and continued to rush towards the star.
Then, the orbits of Planet No. 3, Planet No. 2, and Planet No. 1 were also crossed one after another.
At this moment, Lakai 9352 star has increased to the size of a millstone to the naked eye. After extinction, people can even clearly see the prominence structures at the edge of the star that extend outward like aurora and are blown around by the fierce stellar wind.
The huge Voyage spacecraft is as small as dust in front of the stars. No, not even dust.
At this time, the thrusters, which had been operating at low power for several years, finally began operating at full power. It's just that its direction of advancement has changed at this moment.
Under its propulsion, the Yuanxian spacecraft began to turn violently toward the side of the star. And during this process, the huge gravitational force from the Lakai 9352 star acted on every object, every person, every piece of equipment, and every atom in the Yuanhang spacecraft.
Massive stars in the universe can be used for both deceleration and acceleration. The only difference lies in the choice of track.
At this moment, in the main control room of the Yuanhang spacecraft, Zhao Changxing and a group of civilization leaders and scientist representatives all looked serious.
In front of them was a huge screen. It shows a panoramic view of Lakai 9352 star, and a series of data is displayed next to it.
In the rest of the Yuanhang spacecraft, more than 600,000 spacecraft operation and maintenance personnel are already in place, ready to rush to the battlefield at any time.
Looking at the stars emitting endless power in the image, looking at the constantly changing data, Professor Zhuang Yunwei, who was already old and seemed to be about to collapse in the next moment, couldn't help but sigh.
"I thought that relying on massive stars for acceleration and deceleration would never happen again for us, a civilization of our level. Unexpectedly, now we actually still need to rely on this method. Complete the final deceleration.”
Faced with this situation, people can only sigh in their hearts.
There is no doubt that relying on large-mass stars for acceleration and deceleration usually only exists in primary civilizations with low spacecraft speeds and very little fuel. They need to be careful and save as much as they can.
Because although they make the best use of limited fuel, they are too ink-intensive and a waste of time.
For a civilization that has mastered controllable nuclear fusion and higher-level annihilation of matter and antimatter, it would be better to bring more antimatter if there is time, so that there is not so much time to waste.
"The temperature here is too high and the radiation is too strong. I hope our broken ship, the Yuan Voyage, can survive it."
People prayed silently in their hearts.
At this moment, the more than 600,000 engineers and technical workers have already begun running around and busy.
In the vast space, the huge but tiny Yuanhang spacecraft drew an arc. At the nearest distance of only more than four million kilometers, it gracefully and lightly passed by the star, changing its own orbit. At the same time, the speed also slowed down greatly.
With the help of the ubiquitous gravitational field, the kinetic energy exchange between the Yuanhang spacecraft and the Lakai 9352 star was once again completed.
At this moment, the changed orbit points to the vicinity of Planet 2 in this galaxy.
"Start decelerating at full power."
Zhao Changxing gave the order, and the tail of the spacecraft began to spray violently again. Under this jet, the Yuanxian spacecraft's speed away from the star began to slow down again.
So, it happened to "encounter" Planet No. 2 in space. And with the help of this encounter, another kinetic energy exchange was completed, and along with it, it changed its trajectory again.
This time, its orbit pointed in the direction of its original target, Planet 3. After a period of sailing, it met Planet 3 again.
At this point, not only is its orbit appropriate, but so is its speed. So, after rigorous calculations and one chain of orbit changes and decelerations, it finally successfully settled into the orbit of Planet No. 3.
When Xiao Xi finally reported the result, everyone in the main control room had smiles on their faces.
In the rest of the Voyage ship, cheers had already resounded from every corner that the sound could reach.
At a certain fault handling site, Dai Yunfei put down the tools in his hands tiredly, and a smile finally appeared on his pale and thin face.
"Finally we're here, we can finally get supplies, we can finally eat meat..."
At this moment, he seemed to have smelled the charming aroma of braised pork that could drive people crazy.
