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, collect as many of the 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 seriously insufficient, to the point 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?
This 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 current level of energy shortage is not too high, that is to say, we are pretty lucky.
"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 brightness.
This means that its propulsion power has also been reduced to a corresponding level.
Although based on this deceleration rate, there is no doubt that the Yuanhang spacecraft cannot stay in the Lakai 9352 galaxy.
In this way, a lot 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 relatively inefficient way of obtaining energy. In normal navigation, people obviously do not consider it and do not 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 stars in the distance became brighter and brighter.
At this moment, the Yuanhang 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.
There is no doubt that this is a lot of matter. But 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 stars 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 extremely pure vacuum, but the average number of particles per cubic centimeter in the space has reached tens of thousands.
If that 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. The pressure on all awake people at this moment 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 the civilization leaders both know this. Everyone knows this 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 by 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 Yuanhang spacecraft passed through it without any waves 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.
With a higher acceleration than the Yuanhang spacecraft, it began to decelerate and turn on its own, 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, also known as 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, the star Lakai 9352 has increased to the size of a millstone to the naked eye. After extinction, people can even clearly see the edges of the star, which extend outward like auroras, and follow the fierce stars.
Solar prominence structures blown around by the wind.
The huge Voyage spacecraft is as small as dust in front of the stars. No, it is not even considered dust.
At this time, the thruster, which had been operating at low power for several years, finally began to operate at full power. However, its propulsion direction had changed at this moment.
Under its advancement, the Yuanhang spacecraft began to turn violently toward the side of the star. In this process, the huge gravitational force from the Lakai 9352 star acted on every component in the Yuanhang spacecraft.
Every object, every person, every device, every atom.
Massive stars in the universe can be used to decelerate or accelerate. The only difference lies in the choice of orbit.
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 is a huge screen. It displays 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 gushing out 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 large-mass 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, very little fuel, and the need to be careful and save as much as possible.
Because although they make the best use of limited fuel, they are too cumbersome 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 small 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 has also been greatly slowed down.
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 spray, the speed of the Yuanhang spacecraft away from the star once again began to slow down.
Therefore, it happened to "encounter" with Planet No. 2 in space. With the help of this encounter, it completed another kinetic energy exchange and changed its orbit again.
This time, its orbit pointed in the direction of its original target, Planet 3. After a period of navigation, it met Planet 3 again.
At this moment, not only was its orbit appropriate, but its speed was also appropriate. So, after rigorous calculations and a series 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 Yuan Voyage spacecraft, 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.
