"Hello, new Ruler of the Galaxy." Out of courtesy, Zhang Yuan still replied politely.

He couldn't help but sigh in his heart. As humanity bravely took that step, it was as if the two sides were on the same order of magnitude and were able to talk to each other on an equal footing.

Zhang Yuan now knew that there were not many civilizations of this kind that were willing to manage the galaxy, and most of the fifth-level civilizations, or more advanced civilizations, had their own ideals and plans, and were not willing to spend a lot of time on the endless sunken civilizations......

"We're here to invite you to join us."

The Alev civilization has introduced a very large plan: they actually want to make the entire galaxy, every planet with intelligent life, into a standard intelligence unit.

“…… Then these standard units, connected in series through the faster-than-light network system, form a galactic-level Gaia creature! ”

"Yes, Gaia Crea, have you heard of it, that is, a kind of crowd intelligence. This level of intelligence in group life increases with the number of species. ”

"Each different intelligent creature will provide Gaia with its own intelligence, which in turn will become a whole."

But the galactic-level Gaia creature is not the end, the ultimate goal of Noah's faction is to connect the entire universe and create a cosmic-level group creature - Noah!

"What wisdom this creature will have! At present, Noah's wisdom level is already a ninth-level civilization! Her potential is still growing. ”

"We are grateful if your civilization is willing to take part in this great cause. Our single civilization is so weak that even a small galaxy will take us tens of thousands of years. ”

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

"Yes, it does. But you must know that the vast majority of civilizations in the universe are sinkers, they no longer have room for progress, they have no ideals of their own, and they do not discuss the meaning of life. Wouldn't it make more sense to assimilate them and become a part of Noah? And when encountering a fourth-level civilization with great potential, we don't mind excluding them from the plan...... As a ninth-level civilization, Noah has not many more wisdom units, and one less is not too much. ”

Zhang Yuan asked again: "Occupy a large amount of territory, and other civilizations have been compressed to live in space, won't they sit idly by?" ”

Alev Civilization said very domineeringly: "According to the current known information, high-level civilizations that contradict their ideas are not as powerful as us. As for the other ninth-level civilizations...... Or greater civilizations, each with their own goals, who can understand what we do. ”

"And a more powerful civilization?"

"Of course there is. And under normal circumstances, we don't occupy the entire universe, like the Big Magellanic system next door, we don't occupy it, we just assimilate some of the sunkers. ”

After explaining his philosophy, Alev left the building, leaving only Zhang Yuan, who stayed in a daze......

Will humanity step in to stop this crazy civilization? Not really.

And humanity has jumped out of the chessboard, from a pawn to a chess player. It seems that the Alev civilization will not take the initiative to attack humanity anymore.

In fact, if the superhuman is truly promoted to a fifth-level civilization, it will be no problem at all to shelter the earthlings who have already sunk.

For Noah's faction, there is not much difference between one more or one less standard wisdom unit, just like a cell inside the human body, it doesn't matter if one dies or one lives, and you won't even perceive it.

The Alev civilization will not go head-to-head with a fifth-level civilization because of such a trivial matter, which 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 human beings have seen before is too small and too small, and they are always entangled in some indifferent things. And now, after receiving this series of invitations, it was as if a frog at the bottom of the well jumped out of the bottom of the well, and the sky he saw suddenly expanded countless times!

Then, the ball of light actually lit up again, and it was a faction called the Engineer that sent him an invitation.

The engineer ambitiously said, "We want to know the shape of the universe!" That's what we're aiming for! This shape refers to an abstract description at the mathematical level! We've designed a lot of experiments that will be of interest to you! ”

"The universe is a high-latitude country, and even a very powerful civilization can hardly get a glimpse of the whole picture of the universe, so what shape does the universe have? Is it saddle shape, swim ring shape, or spherical shape? ”

"We've devised some special methods for this......"

Zhang Yuan roughly understood the meaning of this "engineer".

Measurement.

They're using super technology to measure the entire universe!

To give a simple example: the great navigator Galileo Galilei proved that the earth is a sphere by circumnavigating the globe.

Actually, 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 in the shape of a swimming ring. After all, the shape of the swimming ring can also travel around the world.

So how do you rule out this option? The famous Pang-Lai conjecture (theorem) is able to rule this out.

For a simple example, put a rubber band on a ball, and then slowly shrink the rubber band upwards, and the circle will shrink into a point at the pole of the ball;

But if you put a rubber band on the swimming ring, no matter how you move and shrink, it will not shrink into a point.

In mathematical language, any single-connected, closed three-dimensional manifold must be homogeneous to a three-dimensional sphere. This theorem also holds true for high-dimensional spaces.

The tools used by the "engineers" are similar to mathematics and superior scientific and technological prowess.

According to what the engineer just described, they created the giant gravitational source.

“…… If you observe a source of great gravity, you can know that it is a special experiment that we have initiated to measure the shape of the universe, and in the middle of it is also using the natural veins of the universe. However, there is no real conclusive conclusion in this research, and there are several different points of view. ”

"If you're interested in this, consider joining us."

After saying this, the ball of light represented by the engineer left, leaving Zhang Yuan to stay where he was, reminiscing about the description of this super civilization just now.

It's incredible.

Zhang Yuan's heart was surging and excited.

The "giant gravitational source" refers to a gravitational anomaly located near the center of the local supercluster, and galaxies about a few hundred million light-years away are also affected by it!

All galaxies are redshifted, and Harbher's law shows that they are regressing each other, as well as the Earth, but redshifts reveal this irrational phenomenon. Originally, humanity had no idea why this was happening, but it had come to the conclusion that it was a super-experiment by the "Engineer" faction.
