Start a Subspace

Then Karta vividly introduced an organization called Dagui Yang Interstellar Alliance, which is a very loose political organization in the other star system.

In our era, materials are plentiful, and the number of interstellar civilizations is quite rare. In the entire Daguiyang Alliance, there are only a few more than a thousand third-level civilizations that can discover cosmic strings. There are too many unoccupied stars. There are many, and curvature navigation is quite difficult...

Equivalent to each third-level civilization can occupy more than 100 million stars.

Therefore, the main purpose of the Dagui Yang Interstellar Alliance is to spread the excellent culture of various civilizations, conduct some small discussions on the theoretical level, and even give away some knowledge for free.

Oh, you may not know that theoretically only a fourth-level civilization can join this star system-level organization, because only a fourth-level civilization can use cosmic strings to send superluminal signals.

As a one-dimensional space-time, cosmic strings can not only transmit information through vibration, but also transmit information at super-light speed in the space-time inside it.

As for the third-level civilization, it can only be a high-level peripheral member, capable of receiving stellar signals, cosmic string oscillations, and ultra-high-power electromagnetic broadcast signals. These are only light-speed signals, and the transmission speed is too slow, which is not convenient...

...According to the division of the Dagui Yang Interstellar Alliance, a civilization that has developed science and technology is a first-level civilization, that is, a civilization that can receive electromagnetic wave signals from outside the sky and analyze the existence of alien civilizations is considered a serious technological civilization. gone.

This passage surprised mankind again. This Great Guiyang Interstellar Alliance is too prosperous, isn't it possible to give away knowledge for free?

If... If humans have observed the existence of aliens a long time ago, maybe they are more developed than they are now?

After all, the existence or non-existence of aliens can clearly change the traces of social operation.

Karta continued: It is the second-level civilization that invented nuclear fusion. At this time, the civilization is no longer troubled by energy problems, and has the ability to immigrate to the major planets in the star system.

It is a third-level civilization that can discover the existence of cosmic strings.

At this time, the interstellar civilization has reached a fairly developed level, and it is obliged to trigger a star-level broadcast to inform the existence of the Great Guiyang Alliance itself, and through the star broadcast, enlighten other low-level civilizations that there are alien civilizations in the universe.

Civilizations that can use blue matter to 'communicate with blue matter' in cosmic strings are the real fourth-level civilizations.

So cosmic strings are an innate means of communication. Once they are destroyed, they will be the common enemy of the Great Guiyang Alliance. Of course, it is actually very difficult for the fourth-level civilization to really destroy the cosmic strings. They can only use them to communicate at the speed of light.

Our wise men once proposed that as long as we are given another 5,000 years, our green star civilization can also build its own accelerator around the solar system, discover blue matter, and have cosmic string communication means... It's just a pity that there is no time for development Already.

After writing this, Karta showed a very annoyed expression.

Zhang Ran was silent for a while, then asked: Then, what do you mean, it is necessary to build a circum-solar system accelerator to be able to discover the so-called 'blue matter'. How many resources are needed for this?

It is simply impossible for us to have so much material to build accelerators now.

The pinnacle of the earth's civilization accelerator is the LHC located in Europe, with a circumference of 27 kilometers, and it is difficult for human beings to afford it financially. After all, the Large Hadron Collider has no substantive production, and these frontier theories of the universe cannot be used in industry.

The circumference of the Globe Accelerator is 40,000 kilometers, which is simply not affordable for ordinary earth civilizations.

The accelerator around the solar system is even more outrageous. If the circumference is more than 200 million kilometers, it can be regarded as a qualified device, which can collide with a higher energy level.

As for the resources consumed... that is really an astronomical number, a number that human beings cannot imagine. Maybe the annual maintenance cost is enough to support all human beings.

Karta glanced at the screen a bit strangely, the blades trembled, and wrote some words in doubt: Your civilization should also be a third-level civilization, right? The gravitational wave telescope is the product of a third-level civilization, and the artificial intelligence has also reached The level of the third-level civilization. The output of these artificial intelligence alone is enough to feed the entire population, isn't it?

Isn't it a matter of course to build an accelerator around the solar system?

Otherwise, the productivity will be greatly overflowed, and the people will have nothing to do. Is it possible that they will all eat and wait to die? These extra productivity must find a place to be consumed.

In this situation, what else can we do without building a wonder of the world? After all, this is a great spiritual satisfaction! Everyone is discussing the circumsolar accelerator, looking forward to its successful construction bit by bit. For this Isn’t it a very meaningful thing for the accelerator to make suggestions?”

I've even heard that there are many level 4 civilizations building Dyson spheres. Even though the significance of building Dyson spheres is not great... But in the process of building Dyson spheres, there will be many difficulties. Isn't overcoming these difficulties the real meaning? Both artificial intelligence and materials science will develop rapidly...

People were speechless by his rhetorical question...

Perhaps in the era of great affluence, the other party's thinking is correct.

The small-scale peasant thinking of human beings can't keep up with the real era of great prosperity.

At this moment, Karta suddenly thought of something, and clapped his four hands together: Oh, yes, I heard some strange stories, some civilizations abruptly skipped the age of nuclear fusion and entered the era of intelligence ahead of time. Times. They often spread solar panels all over their planets, dwelling on their own planets, not knowing what they are doing...

There are actually quite a few civilizations of this type. They don't communicate at all and develop semiconductors like crazy, but the energy sciences can't keep up.

They can obviously enter the interstellar era and greatly liberate productivity, but instead of doing such meaningful things, they start playing games for all people. There are indeed many inexplicable civilizations like this...

Dagui Yang League has broadcast such a story. This type of civilization is destined to be ridiculed for a long time. Of course, they don't know that they are being ridiculed. It doesn't matter even if they know... But it's nothing, after all, most civilizations are destined to It is backward, and it is destined to be extinct in a catastrophe, which is also the normal state of civilization.

Zhang Ran and the others were silenced by what he said.

Or rather, I don't know how to explain it...

Could it be that they human beings picked up garbage and picked up the third-level civilization, and didn't even absorb the results of garbage?

Where is the fifth-level civilization? Zhang Ran wrote a line of text on the screen.

Karta was silent for a moment, and then introduced again: There is only one real fifth-level civilization, the founder of the Great Return to Yang Alliance, the 'Great Return to Yang Civilization'. But at that time, the 'Great Return to Yang Civilization' was heading towards a technological miracle. After that, it will enter the category of medium civilization, and communication with ordinary civilizations like ours will be meaningless.

Dagui Yang civilization is a great civilization, without its existence, there would be no prosperity of our star system.

(Note: The planetary system refers to the solar system-level structure. The star system refers to the Milky Way-level structure.)

It is said that other star systems are withered and silent, civilizations are isolated islands, there is no communication, no cooperation, the universe is empty, and no civilization is willing to send electromagnetic wave signals, because the transmission of each light-speed signal , will take hundreds of thousands of years.”

The lifespan of an individual is too short compared to the long transmission time of the signal.

This is not the case with our Daguiyang Alliance. We are in a world with frequent exchanges, and we are keen to make our own voices...Almost every month, we can receive messages from other civilizations. Even if this message is It was sent tens of thousands of years ago, so what? As long as there are enough civilizations sending signals, the information density will be large enough, and we can receive signals every month, what an interesting thing.

We Green Stars invented the nuclear fusion project 20,000 years ago and entered the era of secondary civilization.

We gathered global power to interfere with the brightness of our own stars and sent a star-level broadcast. Now that 20,000 years have passed, our star broadcast has only spread 20,000 light years...

The humans were stunned, as if they were listening to a fairy tale. How could there be such an interstellar alliance? But if you think about it, it seems reasonable...

After writing this, Karta became sad, not 20,000 years, but...

Five hundred million years have passed.

20,000 years compared to 500 million years, it is simply inferior.

At this moment, Karta seemed to be hit by the waves of the long river of time, and the memory was divided into two halves. The half came from the distant ancient times, the once glorious interstellar alliance, and all civilizations were looking forward to receiving space signals. Even if this signal was sent by another civilization tens of thousands of years ago, what an interesting story...

The other half's memory comes from modern times, and they are still reduced to prisoners.

Finally, he let out a long quack: Two hundred years after we sent the stellar pulse, we got a reply that there is a first-class civilization in a planetary system a hundred light-years away! This The first-level civilization sent an electromagnetic pulse signal to introduce themselves, and this letter was passed on the road for a hundred years, just to inform us that they exist there.

So we're competitors, and they're moving very, very fast...they...

Five hundred million years is too long, so long that I don't know what happened to my former friends...

Everything seems to be collapsing, things are changing, and even the universe is dead.

But for human beings, this story can be described as incredible.

Zhang Ran held his breath.

This kind of star system actually exists in the world, and the civilization in it is proud of sending cosmic broadcasts? Even if the speed of light travels at a finite speed, so what? As long as each civilization makes its own voice, the information density in the space is high enough to always be able to communicate.

What's more, the fourth-level civilization can also master the super-light speed communication method using cosmic strings.

The formation of this interstellar alliance really gives people a feeling of sudden enlightenment. If human beings have enough technological strength to guide the Milky Way on such a path, what a sense of accomplishment it would be!

Unfortunately, the most precious thing in the world is time. Time can never come back.
