In the second orbit of the 　　 star system, a large number of cosmic organisms appeared. They were active among the meteorites in the asteroid belt. They were exploring many meteorites in a carpet-like manner. They would rather get nothing and never let it go.

　　 The starting points of cosmic creatures are evenly distributed in various positions in the inner asteroid belt. Although a lot of resources are consumed, this greatly reduces the time consumption.

　　 Soon, the asteroid belt in the second orbit of the star system was surveyed by cosmic creatures.

　　 "The report did not find the wreckage of the spacecraft."

　　 In the interplanetary channel constructed by radio, the results of surveying the inner asteroid belt were announced, but the wreckage of the spacecraft was not found as the collectors hoped.

　　 "Are you sure none of the meteorites are missing?"

　　 "Make sure there are no omissions."

　　 The reported biological entity replied very positively to the inquiries of the same family. When the cosmic creatures were searching, they did not even let go of the fist-sized meteorite fragments, but even so, they still couldn't find any clues.

　　 The collectors who got such a reply discussed it again in the channel.

　　 "What do you think of this?"

　　 "Maybe it is naturally degraded?"

　　 "Impossible. This is space, not the surface of the planet. Even the corpses on the dwarf planets still exist. There is no reason why the spacecraft remains eroded away."

　　 "Will that drift out of the second orbit?"

　　 "It's possible, but it's not very big. People are all on the planet. Who is sailing the ship? If there is a companion on the spacecraft, why did the companion leave the person on the planet and leave alone? It doesn't make sense."

　　 "It does not necessarily require people to start the spacecraft. It can be the displacement caused by the collision of meteorites. There is no resistance in the universe. As long as a sufficient initial kinetic energy is given, the spacecraft can float out of the second orbit."

　　 "Are you trying to say that the wreckage of the spacecraft fell into a star?"

In the face of gravitational potential energy, if the speed of all matter decreases, the centrifugal force of revolution cannot be guaranteed, and it will eventually fall into the star. The spacecraft’s wreckage may collide with other asteroids in the inner meteorite belt and move towards the star after the speed drops. The force of gravity drags out the second orbit.

However, this explanation still has opponents, because if the spacecraft wants to enter the second orbit, it must maintain the speed of the second orbit. Only in this way can it be anchored in the second orbit. According to the description of the theory of relativity, the same speed and the same direction. In this case, the matter remains relatively static, so the probability of collision is relatively small.

　　 Another reason is that there is not enough evidence to prove this point. It is impossible to convince all collectors by just relying on brain to supplement the guess.

　　 Just when the two groups of collectors were arguing, a few spoilers joined in, gave the spaceship collectors a hard punch, and wiped out their assumptions.

　　 "It's all quiet, let's put aside those things that are just speculations and can't be concluded. I have another good news to tell you."

　　 "What good news?"

　　 "The half-life time inside the mummy has been calculated."

"how many?"

　　 "About 70 thousand years, the difference between plus and minus is a thousand years."

　　The method used to estimate the age of fossils during archaeology is often used by Huogu. Although it has nothing to do with combat, Huogu is happy to teach collectors the field he is really good at.

　　 The gatherers naturally didn't dare to neglect the things taught by the Supreme Will. They learned as much as Huogu taught them. Not only did they continue to learn, but they also thoroughly understood it.

　　 Before the collectors could digest this information, another collector immediately broadcasted it. The source of the information was the first discoverer of a new civilization who originally presided over the global exploration of dwarf planets.

　　 "I also found something here."

　　 "What traces do those leftover corpses leave behind?"

　　The collectors naturally thought of new discoveries on the mummy, but the individual on the dwarf planet gave a negative answer, it found something else.

　　 "No, it's a discovery on the planet, or you should take a look at it first, and then you will understand."

A physical model of a planet appeared in the channel. This is the dwarf planet with traces of new civilization. The surface of the planet is cratered, and there are a large number of dense craters on one side, layered on top of each other, like raindrops falling on the surface of the water. The ripples are of different sizes, one ring is one ring.

　　On the other side, there are few craters, but because they are few, they are conspicuous enough to allow collectors to notice what happened to the dwarf planet.

　　 That is the crater left by a earth-shattering impact. The ratio of this crater to the dwarf planet, if transferred to the earth, is equivalent to a huge crater in the entire Antarctic Circle.

　　 If such an impact occurs on the earth, then this meteorite is fully capable of smashing the Japanese archipelago below sea level, and it will also spread to South Korea by the way, causing it to sink half of the land.

　　 The huge waves caused by this meteorite impact can spread from one end of the earth to the other end if there is no land obstruction.

　　 The answer is ready to come out, and all the forward inferences of the collectors have been overturned. Because of this shocking information, there was a brief silence in the entire channel.

　　 "This, this is..."

　　 "This dwarf planet does not belong to the second orbit at all. It is not a celestial body that originally exists in this orbit!"

　　 The dwarf planet itself has its own rotation, so the distribution of craters can be scattered and disorderly, but they must be uniform and random. There should not be such obvious and distinct traces.

　　 So the dwarf planet is an alien. This alien broke into the originally stable second orbit ~lightnovelpub.net~, incurring a large number of meteorite impacts and leaving a large number of craters on one side.

　　 This is like running in the rain. If the runner is fast enough, the back of the runner will not be soaked, but the front will be completely soaked.

　　 "Where did it come from?"

　　 "Build a physical model! We need to determine where it came from!"

　　Although there is no eyebrow, the collectors can be sure that this star system must have undergone some drastic changes 70,000 years ago. The meteorite that can strike such a huge crater is also quite massive.

But it is precisely because of such huge mass that their orbits are very stable, and they will not easily change paths and hit the planet due to collisions with other meteorites. In this regard, they are very similar to planets. It can be said that such massive meteorites It is the predecessor of the early planets.

　　 It is not difficult to determine which part of the asteroid belt the dwarf planet enters from. The speed multiplied by the time equals the distance. A simple physical formula is now in use.

　　 The first is to learn the age of the oldest crater among the large number of craters, from which we can roughly determine the time when this dwarf planet entered the second orbit.

　　 According to the energy release of the largest crater combined with the mass of the dwarf planet itself, we can know the speed of the dwarf planet itself at that time.

　　 Knowing the speed and time, the distance traveled by the dwarf planet orbiting the star can be obtained according to the physical formula. This distance is divided by the orbiting distance to get the number of revolutions and the unfinished revolution.

　　 The unfinished revolution is the point where the dwarf planet enters the second orbit.
