Noah and the Engineer

  "Hello, the new ruler of the galaxy." Out of etiquette, Zhang Yuan replied politely.

  He couldn't help but sigh in his heart. As humans bravely took that step, both sides seemed to be on the same level and able to talk as equals.

  Zhang Yuan now knows that there are not many civilizations of this type that are willing to manage the galaxy. Most of the fifth-level civilizations, or more advanced civilizations, have their own ideals and plans, and are not willing to spend a lot of time on On the endless sinker civilization...

  "We are here to invite you to join us."

  The Aleph civilization introduced a very huge plan: they actually want to destroy every planet with intelligent life in the entire galaxy , made into a standard smart unit.

  "...Then these standard units are connected in series through the super-light speed network system to form a galaxy-level Gaia creature!" "

  Yes, Gaia creature, have you heard of it? It is a kind of group intelligence. This kind of group The intelligence level of life will increase with the increase in the number of species." "

  Each different intelligent creature will provide Gaia with its own intelligence and then become a whole."

  But the Gaia creatures at the Milky Way level are not The end point, the ultimate goal of the Noah faction, is to connect the entire universe and create a cosmic-level group creature - Noah!

  "How much wisdom this creature will have! Noah's current wisdom level is already a ninth-level civilization! Her potential is still growing." "

  If your civilization is willing to participate in this great cause, We are grateful. Our individual civilization is too weak. Even a small galaxy will take us tens of thousands of years..."

  Facing such a behemoth, Zhang Yuan suppressed the shock in his heart Emotion, asked: "But once this is done, if all low-level civilizations are assimilated, wouldn't it be difficult to give birth to a new fifth-level civilization?" "

  Yes, it is true. But you have to know that most of the people in the universe All civilizations are sinking. They no longer have room for progress. They have no ideals of their own and do not explore the meaning of life. Wouldn't it be more meaningful to assimilate them and become part of Noah? And When we encounter a fourth-level civilization with great potential, we don't mind excluding them from the plan... As a ninth-level civilization, Noah has one more intelligent unit and one less unit."

  Zhang Yuan asked again: "Occupying a large amount of territory, other civilizations have been squeezed out of their living space. Won't they just sit back and do nothing?"

  The Aleph Civilization said very domineeringly: "According to the information currently known, high-level civilizations with contradictory ideas are not as good as ours. Powerful. As for other ninth-level civilizations...or greater civilizations, they each have their own goals and can understand our approach." "

  Is there a more powerful civilization?"

  "Of course they exist. And under normal circumstances Next door, we will not occupy the entire universe, like the Large Magellanic Cloud next door. We will just assimilate some of the perishers."

  After the Aleph civilization elaborated its ideas, it left, leaving only Zhang Yuan, stay there in a daze...

  Will humans take action to stop this crazy civilization? Not really.

  And humans have jumped out of the chessboard, from chess pieces to chess players. It seems that the Aleph civilization will not take the initiative to attack humans.

  In fact, if superhumans are truly promoted to a fifth-level civilization, there will be no problem if they want to protect the people of the earth who have already sunk.

  For the Noah faction, there is not much difference if there is one more or one less standard intelligence unit. It is just like a cell inside the human body. It does not matter whether one is dead or alive, and they will not even notice it.

  The Aleph civilization will not go head-to-head with a fifth-level civilization over such a trivial matter. It will only waste its time for no reason.

  However, after being exposed to so much information at once, Zhang Yuan's mentality has undergone a very magical change...

  The sky that humans have seen before is really too small, and they are always obsessed with trivial matters. But now, after receiving this series of invitations, it was as if a frog jumped out of the well, and the sky I saw suddenly expanded countless times!

  Next, the light ball actually lit up again. It was a faction called Engineers who extended an invitation to him.

  The engineer said ambitiously: "We want to know the shape of the universe! This is our goal! This shape refers to an abstract description at the mathematical level! We have designed a lot of experiments, and you will definitely be interested!"

  " The universe is at a high latitude. Even a very powerful civilization can hardly get a glimpse of the whole universe. So what is the shape of the universe? Is it the shape of a saddle, a swimming ring, or a sphere?" "

  We designed this for this purpose. I used some special methods..."

  Zhang Yuan roughly understood what this "engineer" meant.

  Measurement.

  They are measuring the entire universe through super technology!

  To give a simple example: the great navigator Galileo proved that the earth is a sphere by sailing around the world.

  In fact, this proof is not rigorous.

  Being able to travel around the world means that the earth may be a round ball, but it may also be shaped like a swimming ring. After all, the shape of the swimming ring can also travel around the world.

  So how do you eliminate this option? The famous Poincaré conjecture (theorem) can rule out this.

  To give a simple analogy, put a rubber band on a ball, and then slowly shrink the rubber band upwards. The circle will shrink to a point at the extreme point of the ball;

  but if a rubber band is placed on a swimming pool, On the circle, no matter how it moves and shrinks, it cannot shrink to a point.

  Described in mathematical language: Any simply connected, closed three-dimensional manifold must be homeomorphic to a three-dimensional sphere. This theorem is also true for high-dimensional spaces.

  The tools used by "engineers" are similar mathematics and super technological strength.

  According to what the engineer just described, the giant gravitational source was created by them.

  "...If you observe the source of giant gravity, you can know that it is a special experiment we conducted to measure the shape of the universe, and we also used the cosmic string, the natural vein of the universe. However, there is no research in this area yet. A real conclusion, and there are several different opinions."

  "If you are interested in this aspect, you can consider joining us."

  After saying this, the light ball represented by the engineer left, leaving only Zhang Yuan staying where he was. , recalling the description of this super civilization just now.

  It's incredible.

  Zhang Yuan's heart was surging and he was extremely excited.

  The "giant attractor" refers to a certain gravitational anomaly located near the center of the local supercluster. Galaxies about hundreds of millions of light years away are also affected by it!

  All galaxies are red-shifted, and Hubble's law shows that they and the Earth are receding from each other, but red-shift reveals this unreasonable phenomenon. The original human beings had no idea why this happened, but now they have come to a conclusion: it was a super experiment carried out by the "Engineer" faction.
