Chapter 325 The New Generation Gene Modification Project

There is also a new generation of general-purpose 3D printing modules, which are newly designed with reference to the repair function of the self-discipline system of the star engine of the Nost civilization.It can realize the printing of millions of industrial parts and industrial products with 3 nanometer precision, and supports tens of thousands of various raw materials from metals to compounds, which is a hundred times the performance of the original 3D printing module.If the original equipment can be called a universal 3D printing module, then the current equipment can be called a universal factory.It can be said that even if human beings lose all modern equipment, as long as they have this universal factory, as long as human beings have enough time, it is possible to rebuild a complete set of their own industrial system.

There are still many achievements like this, but the most important ones are the new-generation genetic modification plan and the new-generation mothership spaceship plan.

The new generation of genetic modification program, this is a genetic optimization program, humans have newly discovered two sets of gene combinations that enhance intelligence, both of which are heritable and stable.This is a necessary condition for gene optimization. If a group of genes can improve certain qualities of human body, but cannot be passed on to the next generation, then such genes will not be able to form an advantage in the human population. It will be lost in time.Many short-lived geniuses in human history may have such genes. They are extremely smart, but their offspring are often mediocre.

There is also stability. If a genome is not stable enough, it is prone to mutations. When it is passed on to the next generation, it will mutate when it is passed on to the next generation, or even during the growth process of this generation, causing its function to weaken or fail. , or even have the opposite effect.This is very dangerous. If such a genome is used rashly, an extreme phenomenon may occur, that is, a certain generation of genetically modified people is very smart, but their next generation or a certain future generation collectively are idiots. For a race like humans that needs to rely on reproduction for the continuation of civilization, it is simply fatal.

This kind of genetic optimization has been carried out several times in the past solar system era, and this time the genetic optimization plan is mainly aimed at the human IQ.Obviously, among the three alien races encountered by the Kunlun Fleet, two races are far superior to humans in certain technological aspects.This has brought a sense of oppression to human beings. What if we encounter an unfriendly alien civilization with technological strength beyond human civilization?A little bit of technological advantage in war may bring subversive war results.So humans need to become smarter in order to achieve more breakthroughs in technological research and development.

The new-generation mothership spaceship plan is a new design by human beings who have re-summarized their experience in 150 years of interstellar voyages.

The new-generation mothership spacecraft scheme is different from the current Kunlun Mountains fleet, where the keel compartments are combined with each other and then connected to the second and third-level units, which are disassembled and combined spacecraft in the form of building blocks.It is an entire super-giant spaceship that cannot be disassembled.

Speaking of this, we must first figure out the original design ideas of human spaceships. There are several considerations for the design of the detachable combination model.First, this kind of combined spaceship with relatively independent modules is relatively easy to build and easy to mass-produce. This was a good solution for humans who were anxious to pack up all humans and escape from the solar system at that time.Second, in this mode, in the future voyage, if a certain module fails or is damaged, the above personnel can be quickly evacuated and the module is discarded, and the damage of one module will not affect the entire spaceship assembly.The third is limited by the material technology and propulsion technology of human beings. Too huge aircraft is a test of the material technology and propulsion technology of a civilization. We all know that all objects in the universe, including spaceships, are affected by gravity and have huge masses. The spaceship is more affected when it is close to the planet, and the Roche limit is farther away. This undoubtedly increased the difficulty of engineering for humans who urgently needed to quickly collect resources to build spaceships, not to mention that super-large spaceships are also affected by their own gravity. If the material technology is not good enough, it is even possible that its own gravity will damage the spacecraft itself.

But now the situation has changed. During the long-term interstellar voyage, humans have discovered that although the previous detachable and combined spaceship structure has many advantages, it also faces many shortcomings.First of all, the space of the entire spaceship is too small.Even if the keel cabin unit of hundreds of thousands of tons sounds very large, it is actually too small for human beings.In order to maintain the healthy state of a species for a long time, it is necessary to simulate its living environment in nature, even though modern humans have undergone many genetic adjustments to make their bodies more suitable for survival in various environments than the earth era.However, the long-term depressed space and low-gravity environment will still have adverse effects on the human body. In order to adapt to this environment, human beings will become more fragile, their bone density will decrease, and their bodies will become slender and tall under low gravity. It is a physical change that a species adapts to its environment.It is difficult to simulate an environment similar to the earth in a space that is too small. Even if the centrifugal force generated by the spacecraft's own rotation is used to simulate the gravity, it is difficult to achieve the ideal gravity effect. Especially the simulated gravity of the combined spacecraft must take into account all levels of units. The force problem of the interface makes the maintenance of the spacecraft a very complicated project.

The second is that small spacecraft actually have limited anti-risk capabilities, which is fine in the open interstellar space, after all, matter is very scarce.But once entering the stellar system, the problem arises. In the stellar system, especially in the outer space, there are a large number of fragmented ice and small meteorites formed by the aggregation of the remains of the original nebula.For example, the Oort Nebula in the original solar system is the remnant of the nebula that formed the sun and its planets 50 billion years ago, and surrounds the solar system.Counting relatively large cometary organizations in such a nebula, there can be hundreds of billions of them.When the spacecraft enters the star system, it must pass through such a nebula, and it is easy to collide with various crushed ice and small meteorites here. You must know that the speed of the spacecraft traveling in the universe can reach up to 10% of the speed of light.It is hard to imagine how much kinetic energy is generated by the collision with meteorites and crushed ice at such a high speed. At this time, the small spaceship is very dangerous because the armor is too thin. If it accidentally hits a weak part of the armor or hits the energy compartment , the consequences of dangerous positions such as the power cabin will be very serious.

Finally, due to the need for front-to-back docking of the spacecraft, if all the 200 keel cabins that have been produced are connected together, it will look like an ultra-long space train. The distance from the tail to the head of the combined queue is as high as 1200 kilometers. The second and third-level subsidiary units are only more than 10 kilometers away, which looks like a strand of hair from a distance.Such a structure obviously cannot guarantee rigidity, so the 200 keel cabins will be divided into 10 small fleets, and each fleet is composed of 20 keel cabins connected front and back.But this creates trouble for coordination and the operation of the entire fleet...
