"What are the traces left behind?" Yan Xia wondered why the builders would go back if the void was built? Did they discover something, or was it because of what they had done in Nanmen II before? "Maybe you will find it more intuitive if you take a look." Ella directly sent the video to Yan Xia. With advanced technology, there will be no blurry shots. The resolution of the video is 128k, which is billion pixels. The common 1080p in the 21st century is million pixels. So this video can be said to be very detailed. In fact, it can't be said that way. After all, it is inside the star. The light here is already bright. Only equipment with special light frequency bands can be used for observation and shielding other light. Fortunately, many of the Federation's current equipment has a wide spectrum coverage, not only visible light, but also all ultraviolet bands and 80% of infrared bands, so the overall video is processed, not just like this. In the video, the inside of the star's void is filled with a behemoth. This stellar cavity is even larger than the three stellar cavities Yan Xia had seen before, with a diameter of more than 200,000 kilometers. However, this giant does not seem small inside it at all. It looks like a rock, but if you look closely, you can find that it has many animal-like structures.
"This should not be my illusion, right?" Illusion refers to the processing of perceived things and connecting them with some things you know, and illusion is the processing of things you see. Living things have such a situation, or as long as the object has consciousness, it will produce this illusion. For example, in a dark corridor, the red paint on the wall is mistaken for blood, and the broom looming in the dark is considered to be human hair. "Obviously not." Ella denied Yan Xia's statement about illusion, which means that it is indeed a living organism. "We found a life inside the star. You can see its rocky appearance. It is a huge silicon-based life. That's what we originally thought." "But the discoverer studied a piece of material and found that it was not silicon-based, but a creation element. Its density was terribly high and it could withstand temperatures of more than 400,000 degrees Celsius. This is consistent with their findings, because there were abnormal stellar winds on the surface of the star. It was speculated that it might be the result of a massive object's impact." In other words, the behemoth crashed into the star and seemed to be unscathed. "But it died." "No weapons were found inside the star system, but it died. There was no damage to its appearance, but its inside had become a mess. It was locked in this space at this time, otherwise it would have fallen directly into the core of the star and merged with the star." Ella said something very scary, and all this happened about 100,000 years ago. This is bad news for the Federation. "So we have reason to suspect that a third party killed the beast." The beast is obviously not a creation of the Federation, but a powerful biological civilization, whose biotechnology is higher than that of the Federation. The force that killed the beast must also be a second-level civilization. What we need to know now is whether the civilization that killed the beast is a star-void civilization or another civilization. Within 1,500 light years, this is already a very close distance. "Are there so many second-level civilizations in the Milky Way?" "There should be!" Ella replied. According to the current situation, the number of second-level civilizations in the Milky Way should be in the three digits, unless the star field where the Federation is located is an accident, and the density is much greater than other places in the Milky Way.
But even so, the Milky Way is no exception. There are dozens of second-level civilizations. This is also because the Milky Way is really big. Even if there are a thousand second-level civilizations, each second-level civilization can control hundreds of millions of stars. How many stars does the Civilization Federation control now? Strictly speaking, the Milky Way can actually support dozens of third-level civilizations, but why not speculate so? As mentioned before, if an industrial civilization appears on Earth, it is obvious that this industrial civilization will begin to expand rapidly to the entire world, even if it cannot truly occupy the entire world. Based on this inference, even if the third-level civilization cannot truly control the entire Milky Way, it will certainly disturb the pattern of the entire Milky Way and make the Milky Way enter a rapid hegemony stage, so the Milky Way will certainly not remain so calm. At least in all the interstellar spaces that the Federation can observe, large-scale wars have not yet broken out. In other words, in the past 100,000 years, only their star field is extremely lively, and other star fields are dead silent. But it is not appropriate to speculate that the Milky Way itself has no powerful civilization. Whether it is light civilization, star hole civilization, or the edge of a civilization indicated by the star map before the olive branch civilization, it indicates that there are many powerful civilizations in the Milky Way. At this time, the Federation has also observed more and more traces of powerful civilizations, but it makes everything more confusing. "The Federation's vision is still too short." "We should try to contact other civilizations." Yan Xia said. Whether it is a positive or negative contact, it is always necessary to find out how many secondary civilizations there are around where you are. "Should we send our army? Or let the explorers explore!" Ella's question made Yan Xia a little embarrassed. If the army is sent, will it cause vigilance? Trigger a war between the two civilizations. And if they just send some unarmed spacecraft, it would be better to let the explorers explore directly. "Explorers." "Let the explorers explore the farther star field. What is the speed of the explorer's spacecraft now?" Ella's answer is 34000km/s, which is the strongest civilian thruster on the market. "Relax to 50000km/s, which will greatly increase the area we explore. Perhaps we should also speed up the research of faster thrusters, at least let our speed increase to 100,000 kilometers per second. I think this is the real entry standard." "If we perform segmented acceleration, what is the maximum speed of our spacecraft?" Yan Xia asked. "An aircraft under 100 meters can reach 170,000 kilometers per second. If it is a starship, there is a special 117-meter starship that can accelerate to 140,000 kilometers per second. For a spaceship, it can only reach 8 seconds at most." Only the kilometer-level can be called a spaceship. The kilometer-level spaceship itself is billion-level, and this speed is already very fast. "Well, let those people transport the remains of the interstellar behemoth back. I hope to study it and only need a small piece of tissue. Since the aircraft under 100 meters can exceed half the speed of light, then transporting a small piece of tissue only requires an aircraft of about 100 kilograms, which should be very fast." Ella's answer is 82% of the speed of light, which is 245,800 kilometers per second. This is not the limit of the Federation, but considering that it is nearly 1,500 light years away from the Federation, they can only use a micro-factory to build a launch device, which is already the highest speed. It is expected that Yan Xia will get the behemoth tissue after 1715.
