Homo sapiens.

Chapter 619
Galaxy 6 years, April.

The ice age of the earth became more and more obvious. At this time, the global sea level has dropped by 5.3 to 5.4 meters.

The Homo sapiens company has not been affected too much, and is still focusing on developing other planets and preventing alien civilizations.

The free world is completely falling apart, and the disintegration of America is a foregone conclusion. Currently, North America is divided into 7 forces.

Although the Europa Commonwealth has re-accepted the British Kingdom, their losses have been very serious. For example, the Nordic region and the Baltic Sea coast have basically no way to carry out open-air agricultural production.

Other forces also declined to varying degrees under the pressure of the Ice Age.

Especially the Kangaroo Country, which is isolated and surrounded by Homo sapiens companies, their economy has completely collapsed at this time, and agriculture is barely self-sufficient, but the good life of lying down and making money before is gone forever.

Homo sapiens is in no rush for Oceania.

After all, the "good days" of the free world are yet to come.

Now it is just the beginning of the ice age, and within the next 100 years, the ice age will gradually develop to its peak, when the global sea level will drop by 90-100 meters, ice sheets and glaciers will grow wildly, and inland areas will become drier and colder.

The core business areas of Homo Sapiens are all in the equatorial region, and no matter how developed the glaciers are, there is no way to reach the equator.

What's more, Homo sapiens' resistance to the natural environment and climate is more than an order of magnitude higher than that of the free world.

Homo sapiens now doesn't need to worry too much, since time is on the company's side anyway.

And Homo sapiens company's top priority is to complete the tests and experiments of the fire of civilization as soon as possible.

In the distant orbit of Saturn.

A huge space station is being arranged. This space station was officially completed in July last year. It was originally a comprehensive scientific research base for Saturn.

At this time, due to the needs of the company, it was temporarily adjusted as a biotechnology research base.

Three different versions of Civilization Tinder are being intensively debugged.

It is estimated that one of the fires of civilization will be debugged in the middle of next month, and then the seeding experiment will be carried out.

Although the research direction of this scientific research base focuses on biotechnology that is highly related to the fire of civilization, it does not mean that there are no other research projects.

For example, the "Comet Project" that is being tested at this time.

I saw an irregular star with a radius of about 50 meters, slowly floating in the void about 200 million kilometers away from Saturn.

Around this star, there are also 5 spaceships.

The five spacecraft used high-power fluorescent lamps and radiation generators at different distances to simulate the radiation and high-energy particles of stars to conduct various irradiation tests on stars.

In this way, stars are undergoing various trajectory deviations.

This is the "Comet Project", the purpose is to use various concealed methods to realize the directional movement of stars.

Since it is necessary to ensure that the spark of civilization can reach its destination safely, it is necessary to find a way to reduce the appearance of various artificial propellers.

Especially after entering the edge region of the planetary system, none of the propellers with obvious characteristics can be used.

In the plan, the spark of civilization will be disguised as a small asteroid, wrapped in rock formations 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 fake star a relatively high speed of movement, ensuring that it can enter the planetary system as soon as possible.

However, once the camouflage star is separated from the auxiliary power system, it means that the camouflage star cannot get the power blessing on the bright side.

How does that asteroid change its direction of movement without human intervention?
The answer is: the gravity of the planets along the way, the radiation of the stars, and the collision of asteroids.

Among these three schemes, planetary gravity can only be tricked once or twice, otherwise it will easily attract the attention of alien civilizations.

Asteroids colliding with each other will damage the camouflage star, so it must not 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 points.

One is that different substances and different colors have different absorptivity and reflectivity of light, which will lead to different radiation light pressures received by various positions of the star.

If it is a spherical star, the influence of radiation light pressure is not so obvious; if it is an irregular star, the influence of radiation light pressure will become more obvious.

Another point is that the composition of some asteroids itself is related, especially the core components of comets, such as water ice, dry ice, and silicate polymers. This special composition will cause the comet to eject water vapor and The flow of carbon dioxide pushes the star to deviate its trajectory.

These two natural orbit changing mechanisms are the items of this test.

The spark of civilization can adjust the color and light absorption rate of various parts of the surface of the comet through a part of the cells densely covered with the comet, so as to control the direction, scale, and radiation light pressure of the water vapor and carbon dioxide jets of the star.

Then through the jets of carbon dioxide and water vapor, as well as the radiation light pressure, the trajectory of the star is changed.

Judging from the current test situation, as long as it is a comet-type star, these three elements can be used to control the trajectory of the star and let the star go to a suitable planet.

This way of changing the trajectory of motion is very hidden, because it is a normal phenomenon in the universe itself.

As long as the adjustment is not too obvious, the range of the changed motion 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 in various planetary systems, and its own danger is not high, so it will naturally not attract too much attention.

Even if it is a first-level civilization with a technical level similar to Homo sapiens, it is difficult to detect a camouflaged comet at close range.

As for the second level of civilization, Homo sapiens company is not very clear about its means, but Homo sapiens company does not want to guess.

Anyway, at this stage, the probability of Sapiens company encountering a second-level civilization is too small.

In a series of radiation exposure tests.

The artificial comet used as an experimental test performed well.

Time passed day by day.

The Saturn scientific research space station is testing the various performances of artificial comets, while studying the carrier of civilization fire.

Before I knew it, it was mid-May.

At this time, the test version of the first civilized tinder was finally produced by scientific researchers.

After completing the development of the first civilized fire test version, the scientific research base immediately planted this civilized fire into an artificial comet, and then directly launched the artificial comet.

The fast-flying artificial comet adjusts the color and light absorption rate of each part by itself, and then deflects in one of the large rocky moons of Saturn.

Finally after a week.

The man-made comet was successfully pulled down by the gravity of the satellite and successfully fell on the surface of the satellite.

With the man-made comet falling on the surface, it means that the seeding was successful, and the next step is to take root and germinate the fire of civilization.

In order to observe the rooting and sprouting process of the fire of civilization, the Saturn satellite has been surrounded by a large number of artificial satellites, and the surrounding is tight.

And the fire of civilization in the impact crater finally confirmed the safety of the surrounding area, and began to activate various working cells, ready to germinate.
