However, although the earthling organization has now mastered a large amount of detailed information about its neighboring star fields, and has never known the location of the universe it is in, it has a lot of detailed information for reference about the situation of many galaxies around its own star system, and it can be regarded as a preliminary prediction of the direction of interstellar colonization that may be chosen in the future.

However, as far as the state of the earth's civilization at this moment is concerned, it is still a somewhat distant and unrealistic thing to carry out a vigorous cosmic development and space colonization in the interstellar era.

In order to achieve this goal, the civilization of the earth still has a lot to do.

The universe is so vast, and the distance in the universe is also extremely far, the nearest star system near the solar system is 4.2 light years away, such a distance, even if you walk at the speed of light, it will take 4.2 years to reach the nearest star system from the solar system.

And if we rely on the spaceships cast by the earthlings themselves to carry out the interstellar journey, even if we do not calculate the time of the spacecraft construction, Sima Mulong estimates by integrating various information and data of the earth's civilization science and technology that even if there is its own microparticle manufacturing system for the processing and casting of precision special parts, the most advanced space flight equipment that can be successfully cast in a short period of time will take about two hundred years to reach the neighboring star system just by empty ship.

The problem is, not to mention how bad this length of time is, it is simply unrealistic, and even more meaningless, the closest Proxima Centauri to the solar system is within the range of its stellar orbit. There is no planet of value at all.

This is the reason why it has been ruined as the first colonization target of the Earth civilization, even if it is indeed the new world closest to the Earth, but it does not even have a valuable planet, why should the Earth civilization spend a huge price to go to that star system to suffer. Is it just for sightseeing? This is a bit too extravagant and unrealistic for a civilization that has just begun to have the ability to explore the starry sky.

In fact, similar to Proxima Centauri, the number of stars in the universe is countless, but for life, for interstellar civilization, the vast majority of them are meaningless existences, at best, they can only be used as a springboard to replenish some spacecraft navigation materials.

Not to mention the fact that there are quite a few star systems. It is a bare star in itself, and there are no planets orbiting in its star orbit, and even if there are planets around, most of the star systems in it are not of development value.

For carbon-based civilizations, only star systems with planetary orbits near the habitable zone have value to colonize, and those planets are too close to the stars. Or planets that are too far away from their stars, and their planetary environments are generally too extreme. Either hot molten iron or cold liquid nitrogen is about to freeze, this kind of overly extreme planetary environment is too unfriendly for ordinary interstellar civilizations, and the development cost is too high. Therefore, they are generally not included in the sequence of colonization and transformation plans, unless they are in those star systems, which have a large number of them, for the corresponding interstellar civilization. Only the existence of ultra-high-value resources can be exploited on an exceptional basis.

As an entry-level interstellar civilization that has just penetrated its tentacles into space, the earth civilization is even more insensitive to this kind of star system that cannot even meet the basic environment of human existence, even if Proxima Centauri has countless rare resource mining stars, the earth civilization will not take action in a short period of time, not to mention, according to the analysis of the detection results, Proxima Centauri is actually not worth a dime for the earth civilization.

In fact, judging from the available information, Earth civilization has found three interstellar colonization directions that are most likely to become a reality.

Among these colonization directions, the final colonization target is at a different distance, the short one is ten light-years away from the Earth, the long one is thirty light-years, and the final targets in these three directions are all large planets in the habitable zone, the smallest of which is also 1.5 times the size of the Earth.

Because they are all in the habitable zone, and already have a certain amount of water resources, as well as planetary magnetic fields and thin atmospheres, although these planets are not the beginning of the survival of the earthlings, but they all have excellent innate conditions, have very high modifiable characteristics, once the earth civilization successfully colonizes it in the future, each planet can carry tens of billions of people in the future, which is undoubtedly very critical for the earth civilization.

For an interstellar civilization, the number of planets it can control, as well as its own population, are very critical basic hard indicators of civilization strength, and if it does not form a certain scale, it will not be able to effectively promote the growth of civilization power.

Just like the current civilization of the earth, with a population of only a few billion, it still belongs to different political systems and cannot form a joint force, in this case, it is difficult to form an effective civilization leap and enter the age of space exploration, which is simply normal.

If you want to enter the age of interstellar exploration, you must at least have a spaceship, right? In the universe, dangers are everywhere, and there are not enough high-speed, sturdy, and powerful spaceship formations, and if you want to cross the sea of stars and colonize other planets, it is simply a wishful thinking.

In the universe, the vast majority of them are a void, often the spacecraft travels a distance of several light years, and there is no suitable resource supply foothold, and what flashes in the void is often a sudden danger, the fine meteorite particles are hard enough and high-speed, and can even penetrate the hull of the spaceship, and some powerful high-energy ray tides can even kill all the lives in an entire fleet at every turn, these ubiquitous dangers, which one does not need to have corresponding protective measures? If not, your so-called spaceship is nothing more than an iron coffin that can fly, not so much for interstellar colonization, but for interstellar takeaway, delivering food and warmth to others.

The problem is, spaceships of such a high standard. Its processing and production technology, how difficult is it, how many links are included in the production chain, and how huge the personnel required are there, it can be said that there are not tens of billions of high-quality talents, and they don't even dare to think about it.

At the current level of science and technology on the earth. Even if you want to make an iron coffin that can fly long distances in space and light years, it is extremely difficult, and this is already taking into account the fact that countless breakthroughs have been made in various scientific and technological links since the rise of the earthling organization.

Without a sufficient population, it is difficult to form enough technology, and without enough technology, it is difficult to produce qualified spaceships. Without a qualified spaceship, it is impossible to carry out interstellar voyages, obtain enough ecological planets, and without enough ecological planets, it is difficult to reproduce a sufficient population, for most of the civilizations that have entered the industrial civilization, the dead cycle that affects them to cross the interstellar civilization is formed in this way.

The boundless sea of stars is the sea that most people try to cross. It has become the biggest obstacle to interstellar civilizations, and the vast majority of civilizations are in front of such a vast and boundless sea of stars. In the end, they can't cross the invisible threshold, and it is difficult to enter the stage of interstellar civilization.

And a few civilizations, in the midst of extremely difficult inner-galaxy cycles, have concentrated their most valuable resources, and while maintaining a large population, they continue to develop and tap the deep potential of their own civilization. In the combination, breakthrough and adaptation of factors that restrict and influence each other such as population, science and technology, resources, environment, human body limits, etc., they finally leap forward, cross the threshold of civilization, and gain the ability to explore and colonize in the starry sky, so as to obtain one space colony after another. As a result, the bottlenecks of population, science and technology, and resources have been violently loosened, and the development of all aspects has embarked on a positive cycle, and finally it has grown into a powerful interstellar civilization under the accumulation of years.

In this process, not only does it require an incomparably strong civilization vitality, a super high population quality, but even a little bit of luck, such as the volume of its own planet is slightly larger, the external environment of the planet is slightly better, etc., only when more convenience is combined together, there is the possibility of truly achieving interstellar civilization, you can imagine how difficult it is!

Of course, this is not to say that all interstellar civilizations have such a hard time and a difficult promotion process.

There are always some civilizations that have good luck and easily crossed the threshold of civilization that is difficult for other civilizations to cross.

Just like the opposite side of the Martian wormhole, in the interstellar civilization system on the other side of the meteorite star sea, there are some star fields, and the innate environment is extremely superior, compared to the situation that the earth civilization can not find a star system for several light years, it is simply an incomparably fertile planetary wilderness, and the resources are incomparably abundant.

In some of the richest star fields, there are as many as dozens of ecological planets in a galaxy, and some are in the same planet orbit, there are two or more planets, revolving around the stars in a common orbit, and several planets, because of the mass, size and other factors, occupy a certain orbital area, and maintain an extremely stable orbital attitude for billions of years.

Moreover, in these star fields, not only are there a huge number of habitable zone planets in the star system, but also a large number of mineral stars in the non-habitable zone, that is, the distance between the star system and the star system is also extremely close, usually the distance between the galaxies is not even a light year.

In such an environment where survival resources are incomparably rich, the possibility of civilization breaking through the limit and becoming an interstellar civilization has of course been greatly improved, under the same number of people, even if their production efficiency and technical level are a little lower, but the incomparably huge number of accumulations still easily allows them to cross the threshold of civilization promotion and become a powerful interstellar civilization.

Even, in the civilization system on the other side of the meteorite star sea, because of the relatively abundant resources, some civilizations that were not up to standard at all in terms of science and technology, with the help of the surrounding environment factors and the convenience of the political struggle of the interstellar civilization, can quickly improve their civilization level, and become a high-flying interstellar civilization, overlooking the indigenous civilizations that are still circling around the planet.

Of course, this kind of civilization system that has become an interstellar civilization with the help of other civilizations, although it has reached the standard of interstellar civilization and has become an interstellar civilization with more than two living planets and the standard of faster-than-light travel ability, but in fact, their position in the interstellar civilization is of course much weaker than that of those civilization systems that really rely on the power of their own civilization to achieve interstellar civilization.

It is also an interstellar civilization, and the difference between them is also quite large, and the differences between the various levels are clear, and the difference is a grade, not only the strength of the civilization itself is very different, but even the right to speak is completely different.

Among the interstellar civilizations, the weakest grade is those outright parallel civilizations, although they are nominally in line with the two standards of interstellar civilizations, but they are actually reflected in the national strength, they are compared with normal interstellar civilizations, and the gap between them can not be remembered, generally speaking, they are the role of the younger brother in the civilization alliance system, and the alliance leader plays the role of the younger brother, thug, consumer market and raw material origin.

The biggest feature of this kind of parallel trade-level interstellar civilization is that most of their so-called faster-than-light travel capabilities are not the capabilities of their own civilizations, in other words, they themselves do not have the production capacity of faster-than-light spaceships, and their spaceships are bought with money from other interstellar civilizations.

Strategic civilization materials like superluminal spaceships are not like ordinary goods that can be bought and sold at will, because to a large extent, this is a real strategic material, the existence of every superluminal spaceship may lead to the birth of an interstellar civilization, or the change of hands of a large area of star field sovereignty, this kind of terrible thing, of course, no star civilization will be open to sale, anyone who wants to buy can buy it, generally the trade of goods of this level is itself with a lot of political considerations and political conditions, usually equivalent to an alliance between civilizations, and the default of buying a ship is the younger brother。

However, there is also a difference between the younger brother and the younger brother, and the treatment is also completely different. Those civilizations that have the ability to independently produce spaceships, and even produce some key or core components in the faster-than-light spaceship system, even if they are junior brothers, their salaries will be relatively higher, and to a certain extent, they are even collaborators of normal interstellar civilizations.

As for the so-called interstellar civilizations that can't even make ordinary spaceships, but can only buy and buy, this kind of is pure injustice, even if it is a dog for a normal interstellar civilization, it is not valued, and its status is much lower in comparison. (To be continued.) )
