Chapter 619 Sowing
Xinghe year 6, April.
The Earth's ice age became more and more obvious, and at this time the global sea level had dropped by 5.3 to 5.4 meters.
The Sapiens company has not been affected too much and is still focusing on exploring other planets and guarding against alien civilizations.
The free world has completely fallen apart, and the disintegration of America is a foregone conclusion. Currently, North America is divided into a total of seven forces.
Although the European Union readmitted the Kingdom of Britain, their losses were very serious. For example, in the Nordic region and the Baltic coast, it was basically impossible to carry out open-air agricultural production.
Other forces also experienced varying degrees of decline under the pressure of the ice age.
Especially the Kangaroo Country, which was isolated and surrounded by the Homo sapiens company. Their economy had completely collapsed at this time. Agriculture was barely self-sufficient, but the good life of making money by doing nothing was gone forever.
Sapiens is in no hurry for Oceania.
After all, the "good days" of the free world are still ahead.
Now is only the early stage of the ice age. In the next hundred years, the ice age will gradually develop to its peak. By then, the global sea level will drop by 90 to 100 meters, the ice caps and glaciers will develop rapidly, and inland areas will become drier and colder.
The core operating areas of the Homo Sapiens Company are all in the equatorial region. No matter how much the glaciers develop, they cannot reach the equator.
What's more, Sapiens' resistance to the natural environment and climate is more than an order of magnitude higher than that of the free world.
There is no need for the Sapiens Company to be too anxious now, because time is on the company's side.
The top priority for Sapiens is to complete the testing and experimentation of the spark of civilization as soon as possible.
In the distant orbit of Saturn.
A huge space station is being built. This space station was officially completed in July last year and was originally intended to be a comprehensive scientific research base on Saturn.
At this time, due to the needs of the company, it was temporarily adjusted to a biotechnology research base.
Three different versions of the spark of civilization are being intensively debugged.
It is estimated that one of the civilization sparks will be debugged and able to carry out seeding experiments by the middle of next month.
Although the research direction of this scientific research base focuses on biotechnology that is highly related to the spark of civilization, it does not mean that there are no other research projects.
For example, the "Comet Project" is currently being tested.
I saw an irregular celestial body with a radius of about 50 meters slowly floating in the void about 2 million kilometers away from Saturn.
There are five spaceships surrounding this planet.
These five spacecraft used high-power fluorescent lamps and radiation generators to simulate stellar radiation and high-energy particles at different distances, and conducted various irradiation tests on the stars.
In this way, the stars are undergoing various trajectory deviations.
This is the "Comet Project", and its purpose is to achieve the directional movement of celestial bodies using various covert methods.
Since we want to ensure that the spark of civilization can reach its destination safely, we must find a way to reduce the appearance of various artificial propulsion devices.
Especially after entering the edge of the planetary system, none of the various distinctive thrusters can be used.
According to the plan, the spark of civilization will be disguised as a small asteroid, wrapped in rock and ice shells, to ensure that it can sneak into the interior of the planetary system without warning.
Although before entering the planetary system, the auxiliary power system will definitely give the disguised star a relatively high moving speed to ensure that it can enter the planetary system as soon as possible.
However, once the camouflage star body and the auxiliary power system are separated, it means that the camouflage star body cannot obtain the obvious power support.
How can an asteroid change its direction of movement without human intervention ?
The answer is: the gravity of planets along the way, stellar radiation, and collisions between asteroids.
Among these three options, the planet's gravity can only be used once or twice, otherwise it will easily attract the attention of alien civilizations.
The collision of asteroids will damage the camouflaged star, so this method cannot be used.
What can be used directly is stellar radiation.
The reason why stellar radiation can change the trajectory of asteroids is due to two factors.
One is that different substances and different colors have different absorption and reflectivity of light, which will cause the radiation light pressure at different positions of the star to be different.
If it is a spherical star, the influence of radiation light pressure is not very obvious; if it is an irregular star, the influence of radiation light pressure will become more obvious.
Another point is that it is related to the composition of some asteroids themselves, especially the core components of comets, which are water ice, dry ice, and silicate polymers. This special component will cause the comet to eject water vapor and carbon dioxide gas after being irradiated by the star, thereby pushing the star to deviate its trajectory.
These two natural track change mechanisms are the subjects of this test.
The spark of civilization can adjust the color and light absorption rate of various parts of the comet's surface through a portion of cells densely covered on the comet, thereby controlling the direction, scale, and radiation pressure of the star's water vapor and carbon dioxide jets.
Then, the trajectory of the star's movement is changed through jets of carbon dioxide and water vapor, as well as radiation light pressure.
Judging from the current test results, as long as it is a comet-type celestial body, these three elements can be used to control the trajectory of the celestial body and make it move to a suitable planet.
This way of changing the trajectory of motion is very covert because it is a normal phenomenon in the universe.
As long as the adjustment is not too obvious, the change in the movement trajectory is not too large, and the time is not too short, it will not attract attention.
After all, this kind of small comet is a relatively common celestial body among various planetary systems. In addition, it is not very dangerous, so it will naturally not attract too much attention.
Even a first-class civilization with a similar technological level to Homo Sapiens would find it difficult to detect a disguised comet at close range.
As for the second-level civilization, Sapiens Company is not very clear about its methods, but Sapiens Company does not want to speculate.
Anyway, at this stage, the probability of Homo sapiens encountering a level 2 civilization is too small.
In a series of radiation exposure tests.
The artificial comet used for experimental testing performed well in all aspects.
Time passes day by day.
The Saturn research space station is testing the performance of the artificial comet while studying the carrier of the spark of civilization.
Before we knew it, it was already mid-May.
At this time, the test version of the first spark of civilization was finally produced by scientific researchers.
After completing the development of the first test version of the civilization spark, the scientific research base immediately planted the civilization spark into an artificial comet and then directly launched the artificial comet.
The artificial comet was flying fast, adjusting the color and light absorption rate of each part, and then heading toward one of Saturn's large rocky satellites.
Finally after a week.
This artificial comet successfully fell on the surface of the satellite with the help of the satellite's gravity.
As the artificial comet falls to the surface, it means that the sowing has been successful, and the next step is for the seeds of civilization to take root and sprout.
In order to observe the process of the taking root and sprouting of this civilization, the Saturn satellite has been surrounded by a large number of artificial satellites, making it impossible to get through.
The spark of civilization in the crater finally confirmed the safety of the surroundings and began to activate various working cells, preparing to germinate.
