Chapter 252 Space Carrier, Humanity One

When the population increases in the future, the scientific research population will also increase. A scientific research population of hundreds of millions, even billions, or billions, coupled with Han Yang's participation, will provide efficient organizational capabilities, and internal friction will be reduced to The lowest, the communication cost is reduced to the lowest, and the overall efficiency is raised to the highest level. Even Han Yang can't imagine how huge the development potential of such a civilization will be, and how rapid the technological progress will be.

At that time, the powerful scientific research power of human civilization will be fed back to itself, allowing it to have greater computing power and a fleet with stronger combat effectiveness, allowing its vision to expand into a wider space...

Human civilization and its own glorious future have been presented to Han Yang.

However, at this stage, we still need to be down-to-earth.

Han Yang thought about the future and once again devoted his computing power to almost endless scientific research and industrial construction.

With the joint efforts of the Eta people, human scientists, and Han Yang, the first space carrier owned by human civilization was finally built.

Compared with the large mother ships that existed in the fleet in the past, the space carrier has a higher-level positioning.

It is specially developed for interstellar ultra-long-distance voyages of large quantities of cargo.

It is a truly interstellar spacecraft.

At this moment, the Humanity No. 16 Space Carrier appeared in front of Han Yang, with a length of 3 kilometers, and both the widest and highest points were kilometers.

It consists of a cylindrical core cabin with a diameter of about 800 meters, and a total of 40 smaller cylinders extending from the core cabin with a diameter of about 1.1 meters and a length of about 500 kilometers.

Overall, it looks like a mace.

The unladen total mass of this mace is as high as 2.6 million tons. When fully loaded with cargo, consumables and supplies, the total mass will climb to about 5 million tons.

The fuel loaded on it can support it to accelerate and decelerate at 40% of the speed of light a total of four times, and support inertial navigation consumption for more than 100 years.

That is, starting from the solar system, accelerating to 40% of the speed of light, arriving at another star system, such as the closest galaxy Centauri, then decelerating from 40% of the speed of light to zero, then accelerating back to the solar system, and then decelerating to zero. If such a voyage is taken as one time, it can be executed completely once.

Of course, usually it will be replenished after arriving at a destination. Excess fuel and supplies are used as redundancy.

As an indispensable vehicle for large-scale interstellar navigation, and an indispensable important equipment for interstellar warfare and large-scale interstellar trade, transportation, and development, Han Yang has invested a lot of energy in the research and development of the space carrier. and hard work.

At this moment, in Neptune Port, the Humanity Space Carrier No. 1 is fully loaded.

Its core cabin is already filled with various supplies and materials that require special environment storage. There are many smaller cylinders, or iron rods, extending out from its body, and warehouses have been fixed one after another on them.

Its total mass has reached the design upper limit of 5 million tons.

"Then... let's go to the Nanmen II Galaxy to truly verify the interstellar super-heavy spacecraft technology I have mastered at the moment..."

With the blessing of Han Yang and millions of humans and ETA scientists, 500 high-power ion thrusters at the rear of the Humanity space carrier and more than auxiliary engines equipped on the hull simultaneously ejected A bright light appeared, pushing it forward slowly.

Under full power propulsion, its acceleration will reach 1 meter per square second.

Under this acceleration, it will take 3.8 years to accelerate to a maximum speed of 40% of the speed of light, then coast inertially for 6.7 years, and then take another 3.8 years to decelerate to a low speed of more than ten kilometers per second, and then dock in the South On the orbit of a planet in the Gate galaxy, the interstellar voyage was finally completed.

It took a total of 14.3 years.

After that, the numerous mechanical equipment and materials loaded on it will be transported to that planet, and material exploration and related research will be carried out on that planet, as well as tasks such as mineral collection, fuel and material replenishment.

After staying there for about 5 months, it will start accelerating again and return to the solar system, taking another 14.3 years to return.

Coming and going, including the time spent in between, it took a total of about 29 years.

In the vast space, the figure of the huge Humanity Space Carrier No. 1 gradually faded away, and finally disappeared completely. The first interstellar voyage in the history of human civilization has begun.

According to Han Yang's previous theoretical calculations, a triple star system composed of one red dwarf and two yellow dwarfs, like the Nanmen Galaxy, should contain some special and highly valuable minerals. substance.

Mining it back will help the development of human civilization.

But this is not actually the main reason why Han Yang embarked on this interstellar voyage.

The main reason is that Han Yang needs to actually conduct an interstellar voyage to test and verify the technology in his hands.

After all, after truly entering the interstellar era, if you want to enter the universe on a large scale, this kind of heavy-duty long-range transportation technology is indispensable.

At the same time, Han Yang also broke the normal development routine.

Under normal circumstances, to verify interstellar voyage technology, one would first launch a few detectors, then send a few small spacecraft that do not need to be recovered, then a cargo ship, step by step, and finally a space carrier.

Han Yang got it right in one step, skipping all the early steps and reaching the last step.

There is no way. In the early stage, all of Han Yang's energy was involved in the cause of liberating the solar system, and there was really no spare computing power to develop interstellar navigation-related technologies. However, the relevant technical and theoretical reserves have been completed.

Just like the high-efficiency ion thrusters used by battleships, they can be used on space carriers with modifications.

At most, this only involves some application-level research and does not involve basic theory, so the difficulty is not high.

In other words, Han Yang had the technical ability to develop large-scale interstellar navigation very early, but he never did it.

Now that he has the conditions, time is too tight, and there are too many external risks and crises full of uncertainty. He really cannot allow him to take it step by step slowly. He can only do it like this now, directly in one step, and directly verify the final level. Technology.

Time passes slowly. Soon, the speed of the Humanity Space Carrier No. 3.15 increased to about 5000 kilometers per second, and the total distance it traveled was about billion kilometers.

Prior to this, the farthest voyage Han Yang had ever made only traveled about 2700 billion kilometers.

However, when the distance is expanded to 5000 billion kilometers, the scene is actually similar to that of 2700 billion kilometers. They are all the same emptiness, vastness, coldness and nothingness.

Within the boundaries of the solar system, the farther away from the sun, the thinner the density of matter.

The entire solar system, from the inside out, consists of the four rocky planets, the asteroid belt, the four gaseous planets, and then the Kuiper Belt and the ecliptic discrete disk.

But even if the ecliptic is a discrete disk, the distance from the sun is only tens of billions of kilometers at most.

From beyond the discrete disc of the ecliptic to the true boundary of the solar system, a distance of up to trillions of kilometers all belongs to one region, the Oort cloud.

The Oort Cloud is similar to the Kuiper Belt in that it is composed of a large number of small icy objects. But the Oort cloud is sparser and wider.

Its farthest point extends to about one light-year from the sun, or about 9.2 trillion kilometers.

That's the true limit of the solar system. Because the movement of celestial bodies beyond this place is no longer controlled by the sun and no longer revolves around the sun.

In the vast void, the Humanity Space Carrier No. 1 has been accelerating.

3.8 years after its departure, the main and auxiliary engines of the Humanity No. Space Carrier were shut down, stopped accelerating, and truly entered a state of inertial navigation.

Its speed has reached 40% of the speed of light, which is about kilometers per second.

From this moment on, these engines will not start again unless they are gravitational perturbations from other stars in the universe, or encounter collisions with interstellar dust clouds that cause the course to deviate and require adjustment of the orbit.

At this time, the Humanity Space Carrier No. 7.18 is about trillion kilometers away from the sun, which is still less than one light-year.

About three months later, Humanity 1 space carrier passed through the outer layer of the Oort cloud, leaving the solar system for the first time in the history of civilization.

The brightness of the Sun seen from here has been reduced to only magnitude -2.8, which is about the same brightness as Jupiter seen from Earth.

It is still a bright star, even quite bright, but it is just an ordinary star among thousands of stars in the vast universe.

But such an ordinary star is the master of almost all stars in the Oort cloud.

If there is life on the stars here, then unless the technology has developed to a certain level, they will never be able to imagine that the planet they live on is actually orbiting such an ordinary star in the vast universe.

At this moment, even Han Yang couldn't help but sigh in his heart.

“At this stage, I have just left the scope of the solar system, similar to human beings who have just stepped out of their homes, but they are already so far away.

And the small solar system is nothing compared to the Milky Way, no, just compared to the Orion spiral arm.

The small Milky Way is nothing compared to the vast universe.

This universe is really too vast... How many secrets and wonderful things are hidden in such a vast universe?

But... one day, I will lead human civilization to the pinnacle of civilization and have the ability to survey the vastness and splendor of the entire universe. "

Han Yang secretly made up his mind.

Now more than four years have passed since the departure of the Humanity No. 1 Space Carrier. During this process, Han Yang kept an eye on its status through various monitoring and control equipment installed on Humanity One.

Based on these data, Han Yang went through some transformation and optimization to design a second space carrier, Humanity 2, with more advanced technology, more reasonable structure, and higher efficiency, and launched it again.

After that, there are humans No. 3, No. 4, No. 5...

Before Humanity 1 arrived at the Nanmen II system, six more space carriers had already set off, which also meant that Han Yang had seven different samples to verify the technology related to interstellar ultra-long-range and super-heavy spacecraft.
