An Alien Fleet

  0.19 light-years, which is not close at all. It takes 0.19 years for light to propagate, which is about 69 days.

  Therefore, the images observed by people occurred 69 days ago.

  The reason why the unknown celestial body can be observed in this environment is due to the super observation ability of the "South Pole Star" space telescope. In addition, the mass of this unknown celestial body is too large, and the dim starlight produces light around it. A relatively obvious phenomenon of gravitational lensing.

  Humanity's Shanhai battle star has only one-fifth of its mass!

  The main cause of the gravitational lensing effect is that space-time will be distorted near massive celestial bodies, causing light to bend when passing near massive celestial bodies. If there is a massive object in a straight line from the observer to the light source, the observer will see one or more images caused by the bending of the light.

  An astronomer explained: "According to our observations, the speed of this unknown object is likely to exceed the speed of light, that is, it is traveling in curvature... so it will produce a large number of ghost images."

  "With a mass of 2.3 times that of the Earth, it is likely that many planets are relatively close to each other and are traveling at high speed, which causes a certain degree of error in telescope observations."

  "This observation data is inaccurate. There are a lot of ghosts in it."

  Zhang Yuan frowned. Indeed, the mass of the moon is only one-eighty-one times that of the earth. The new human civilization Shanhai battle star is much smaller than the moon, probably less than one-third of the moon.

  If the planet's gravity is too great, it will have a considerable impact on the entire industrial environment, and it will be more difficult to develop. It is basically impossible to build a world-wide space port.

  Calculated based on 2.3 times the mass of the earth, wouldn't there be hundreds of planets? This is of course impossible. The main reason is because the planet's super-light voyage produces a large number of ghost images.

  "Are there any more observations?"

  An astronomer said: "No, this observation data was also discovered by us accidentally. Due to the insufficient amount of data and excluding some error interference, we speculate that the number of planets in the opponent's fleet is about 10-15."

  All in all, no matter how you calculate it, you can calculate that a very powerful fleet will pass by humans. This is a real hammer.

  Since the story happened 69 days ago, the information is greatly delayed. Maybe in the next second, humans will have discovered this fleet appearing nearby!

  The emergence of this kind of speculation suddenly made people feel horrified.

  "Let's talk about safety first. Should we retreat as soon as possible?" Captain Feng cleared his throat and asked. "Where is the destination of this powerful interstellar fleet?"

  However, after careful discussion, everyone gradually felt relieved, because in the super-light state, separated by a layer of curvature bubble, the ability to receive external information is very poor, and even aliens cannot avoid this cosmic-level problem.

  Therefore, just because humans can "accidentally" observe each other does not mean that the other party can observe themselves.

  Even if it is observed, it is likely to be mistaken for a lonely planet, and it is unlikely to be able to observe various surrounding spacecraft. In this case, the possibility of deliberate investigation is not high. The number of lone stars that have been thrown out of the planetary system is not large in the universe, but it is also quite a lot. Some three-body systems will throw out or swallow the surrounding planets. Lose.

  "Which direction is this fleet heading in?" an officer asked.

  The chief astronomer replied: "It should be in the direction of the Dyson sphere!"

  Is the direction of the Dyson sphere...

  Zhang Yuan suddenly breathed a sigh of relief. I don't know how to describe this feeling. Is it gloating or something else...

  A sense of thankfulness?

  Indescribable.

  "This fleet won't be the main fleet of the Aleph civilization, right?" Li Zhendong guessed: "The Dyson sphere is so famous, it must be a key target. Alas, the civilization over there is in misery! It has suffered."

  Zhang Yuan shook his head: "That's not necessarily true. Even the fifth-level civilization may not be able to defeat the Dyson Sphere's combat power. Maybe Tabby's civilization still has a hand in the end, the super-intelligent Omega, which is specially used to deal with monist civilizations. Woolen cloth?"

  "That's true...that place might be busy!"

  Omega is indeed a very weird intelligence. Various civilizations have been making noise there for so long, but they have not seen it come out to manage it. Maybe it thinks that deciding a winner is a good thing. Anyway, as long as there is civilization to protect the Dyson Sphere.

  But from now on, it's uncertain.

  Tubby's civilization advocates the concept of pluralism and likes to make the entire galaxy more lively. This concept is a great enemy of monist civilization. Just like the Aleph civilization assimilated all the interstellar civilizations there, the Dyson sphere is likely to lose its maintenance. From this logical point of view, it is harmful to the operation of the Dyson sphere itself.

  Of course, this kind of thing is possible.

  Artificial intelligence Omega may or may not take action, it's all just people's own random thoughts.

  After discussing for a while, someone asked again: "Where is this fleet coming from? Where do they come from?"

  "I don't know. It's difficult for us to observe these traces. The observation traces are too blurry."

  Interstellar navigation is not necessarily straight forward. Sometimes it will deliberately avoid some large gravitational sources, avoid meteorites, or avoid cosmic strings, etc., so humans cannot make direct speculations.

  The episode quickly turned into a confidential file, and it was slightly worrying.

  The situation in the Milky Way is becoming more chaotic. Maybe this chaos is not far away from us, and we don't know when we will encounter it...

  Humanity's current strength can barely escape the Milky Way. The Large Magellanic Cloud is 160,000 light-years away from the Milky Way, and the Small Magellanic Cloud is 210,000 light-years away from the Milky Way.

  This distance can be crossed with the support of a battle star, but it will take a long, long time, at least tens of thousands of years.

  But humans are not familiar with the conditions of these two galaxies, and escaping directly from the Milky Way before there is enough information is a gamble.

  Maybe...these two galaxies are more chaotic?

  "Then let's do it. Our fleet will set off as soon as possible and hurry up to reach the next destination."

  Since nothing more could be discussed and no more information could be obtained, everyone quickly dispersed and started their own work.

  Then, 10 days later, the new human fleet set off again, a full month earlier than expected. However, such plan changes happen from time to time, and the public does not react much.

  Just like that, a planet and six large spaceships disappeared into the vast night sky...
