"It's time to take our first step, which is also a big step for our civilization." A spaceship is leaning against an asteroid factory. This spaceship is 700 meters long and looks like a whale without a tail. The upper part has only a little arc, and the bottom of the spaceship has a big belly. If it is placed in the water, some people will believe it is a ship. But this is a spaceship, with a deadweight of 740,000 meters, and the technological content is also top-notch. A life that looks about the same height as a human, but has a body as slender as a stick insect and limbs that feel like bamboo sticks, looks at this masterpiece of its own civilization with joy. At this time, it can look back and see the mother planet that gave birth to it. It is a planet with only 87% of the mass of Mars. Its surface even has only a thin atmosphere. The entire surface of the planet is covered with ice. It takes about 417 Earth days to orbit around the star. In each orbit period, only 78 Earth days of ice on the surface of the planet is melted, because at that time, the orbit is closer to the star with the ellipse of the orbit. It was on such a harsh planet that their civilization was born. How difficult it is. "If a planet like ours can give birth to a civilization, there should be many civilizations in the universe. However, there is no accurate record of alien life in the more than 14,000 years (about 16,000 years) since our civilization was recorded. Does this mean that our civilization is extremely advanced?" Every civilization will ask such questions.
If we stand on a higher stage like the Federation, we will naturally know that the reason why many civilizations did not encounter alien civilizations in the early stages of development is that the universe is too big and the space that civilization can occupy is limited. In addition, the conditions for the birth of a higher-level civilization are more stringent. For example, the Olive Branch Civilization, the Silk Civilization, and the Federation all took tens of thousands of years to become a relatively mid-level civilization among the Level 2 civilizations. If it wants to be stronger, it will take another million years, or even more million years. In the theoretical model of the Federation, the development time of a general Level 3 civilization is about 30 to 40 million years, and the faster ones can reach 10 to 20 million years. If it has experienced many technological explosions, it will take at least 5 million years. Although this is not long for the life of the universe, it is definitely not short. If the cycle of a planet from the birth of the lowest life to the birth of higher intelligent life is taken into account, and the destruction and self-dissolution of civilization due to various reasons, then the cycle and possibility of the emergence of civilization above level 3 will be extremely long and extremely small. However, this can only be felt and seen from a higher position. "Our civilization has completely controlled our mother star and started to develop the surrounding planets and use our own stars to generate electricity." "This time, we hope to take our first step and conduct an interstellar colonization. This is great, and we will move towards the real interstellar era." It is a stupid and smart decision to conduct cross-star system exploration in the early stage of interstellar. If there are no other civilizations outside, then doing so will undoubtedly bring about the development of cutting-edge technology and increase energy mining. After all, most of the matter in the star system is in the star, and more than 90% of the matter other than the star is inside the planet. The resources that can be mined on the surface of the planet plus the resources that can be mined on the asteroid may actually only be one ten-thousandth of the total matter of a star system. It is also necessary to consider that most of this one ten-thousandth are materials with extremely high abundance, such as silicon and carbon, but not so advanced in low-level civilizations. These materials can be used as infrastructure, but they are powerless to make spacecraft or other energy devices. So in general, the resources of a star system are still relatively limited, especially when most of the universe is red dwarfs. "Ignite!" The leader of the civilization waved six hands. The spacecraft completed the ignition, and the mechanical arm that controlled its stability was released, and it began to accelerate forward.
The first stage of acceleration is not completed by the spacecraft itself, but by the propulsion device at the rear, such as the rocket thruster. After the acceleration fuel is exhausted, this section of the propulsion device will be detached. There are 3 sections of such a propulsion device, and finally the spacecraft's own propulsion device will accelerate. Until 3 days later, it finally accelerated to an ultra-high speed of . The nearest star system is light years away from them. It is a star system larger than them. The mass of the main star is 27% more than that of their parent star. There are also 4 planets in the star system, including 2 gas giants. That is an ideal place. The journey takes 4,000 years. The mission itself is controversial. Most life believes that if it develops for another 1,000 years, the spacecraft it makes will definitely catch up with the former, so why waste resources on the first spacecraft? However, like other technologies, most people don’t know how many failed products there are before the finished products they have seen. No technological breakthrough is achieved overnight. There will always be pioneers to collect data. All researchers know that the mission of this spacecraft is not to achieve, but to process, and it is also a symbolic meaning, a hope for the advancement of civilization. If there is nothing there, then who will believe that they can do it? This is what it carries. Its name was also officially named "Departure", which means not only the departure of the spacecraft, but also the departure of civilization. About 134 years later, the spacecraft left the star system and entered deep space. This moment is worth cheering. The original witnesses of the civilization's spacecraft's departure have long died, and a new generation of life has inherited and witnessed all this. However, 482 years later, the civilization lost contact with the Departure. There were frozen civilized lives on the Departure. They woke up in the spacecraft alarm. The captain checked the log and found that they had seriously deviated from the course. Some high-energy particles in the interstellar impacted their spacecraft, causing the computer host to malfunction. Thousands of lives anxiously repaired the spacecraft and corrected the course. About 29 days later, the spacecraft radar showed that an object was approaching rapidly. The speed of this object exceeded any meteorite they had observed before, and the size was also quite large. The object approached them in just a few days. These lives gave up observing with equipment and turned to look through telescopes with their naked eyes. Then, they saw a scene that they would never forget. A behemoth started out as a tiny dot, then an hour later it became larger than the surrounding starlight, then the naked eye could see its details, then it became as big as an eyeball, and after another two hours, it filled the field of vision. They gave up looking through the telescope and looked directly out through the glass. They saw a dark behemoth passing in front of their spaceship, it was like a planet flashing in front of them, every groove on it was enough to hide their spaceship, every rivet was heavier than their spaceship, the thick gun barrel could even hold an entire city, and that was just a tiny cannon on its hull, there were thousands of such gun barrels on the entire ship. "Civilization, a powerful and advanced civilization." The lives on the Sailing Ship trembled when they saw this scene, they couldn't even stabilize their bodies, and fell to the floor of the spaceship one by one. However, it was not over yet. More signal sources appeared on the radar.
They looked like living spaceships, each smaller than the previous one, but also huge. A bulge on the spaceship could accommodate several Sailing Ships. What a powerful civilization this is? How small and ridiculous is my own civilization in front of it! At this moment, all the lives on Sailing Ship lost their faith and hope for the future of civilization.
