Beneath Deep Space

In the eyes of interstellar civilizations, K-class civilizations are not divided into categories. Whether they are primitive races or modern civilizations, as long as they have not passed the Great Filter, they are all called K-class civilizations.

But since the beginning of L-level civilization, there has been a relatively rough division process.

Excluding the S-class civilization where the divine dragon is seen but never seen, the L-class civilization is the real main body of the starry sky...

From the perspective of science and technology, only by realizing a [large-scale fusion reactor] and completing [a sublight speed spacecraft of about 5%] can we have the means of stellar-level interstellar navigation and achieve a true L1-level civilization.

Facing Yi Feng's questions, Hei began to proudly show off his knowledge. At this time, he felt particularly happy.

Since he has chosen to join the new human civilization, he must fulfill his duties. He is not a half-hearted person.

"Captain Yu, needless to say the benefits of crossing the Great Filter. Every L1-level interstellar civilization has achieved a qualitative change in civilization and can easily crush the vast majority of K-level civilizations. Is this no problem?"

Yu Yifeng nodded: "What about L2? The discovery of dark matter theory is not difficult, right?"

In his view, since humans achieved fusion, they naturally discovered dark matter, thus realizing the subsequent curvature engine.

"Yes, that's right, as long as a strong enough hadron collider is enough..." Hei nodded and said: "But not all interstellar civilizations will madly build hadron colliders bigger and stronger. , so they won’t necessarily discover dark matter soon..."

"Moreover, exploring curvature bubbles is also very difficult and requires a long process."

It's right to think about it. Humanity has only been exploring curvature bubbles for twenty or thirty years, but it has achieved considerable results.

That's because... most of the space structures are copied from the Green Light Civilization, which can be said to have taken a shortcut!

Without the data obtained when attacking the Green Light spacecraft, the development time of the curvature engine would be significantly lengthened. Yu Yifeng couldn't help but smile, wasn't it a blessing in disguise?

All in all, L2 civilization is represented by the emergence of the "dark matter" theory and the subsequent curvature engine.

"Dark matter" theory, a huge milestone.

Even...human beings still can't figure out whether some "dark matter" is zero-point energy or a dynamic field, and they are still exploring its ultimate nature.

Maybe just like the wave-particle duality of photons, "dark matter" also has two properties. This is also possible.

The level of civilization is, of course, based on the milestone of a certain science as the dividing point, rather than the difficulty of a certain technology. No matter whether this "theory" is simple or difficult, as long as you discover it and stand on it, the level of civilization will rise one level.

Of course, if there is a gap in level, the gap in strength is even greater.

L1 level, 5% of the speed of light, only 10% at most.

But what about L2? Beyond the speed of light!

"So, what about L3 level? What technology?"

"nano technology."

"Nanotechnology?" Yu Yifeng asked doubtfully.

"Yes, to be precise, it is 'nano-level control'. Of course, it is not the current superficial level, but to achieve true atomic level control."

"Including a large number of nanomaterials, nanorobots, etc."

"This technology requires civilization to have a deep understanding of the microscopic level, and involves the Casimir effect. Sorry, my core memory does not have this information..."

"But I know that through these technologies, we can create some materials with exaggerated properties, including friction-free materials, and use the Casimir effect to make small amounts of vacuum energy and dark energy..."

Hei finally added: "As far as I know, the real controllable nuclear fusion technology was achieved at this stage."

Is frictionless material... really possible?

Yu Yifeng paused, feeling a little fantasy in his heart. The L3 level technology was already so exaggerated... It was almost impossible to exist in previous theories, right?

He asked curiously: "Where is L4?"

"Gene dynamics, brain topology, civilization at this stage can study the initial generation of intelligence and initially transform life from the genetic level... A lot of information has been given to you."

"In fact, human brain chips are equivalent to L4-level technology... This kind of technology transcends the level of civilization itself."

"...Where's L5?"

"I don't know either..." Hei shook his head. His original civilization stopped at L4.

He said somewhat solemnly: "Your Excellency Yu Yifeng, I would like to remind you that the division of civilization is very rough. Each technological line is almost endless. Even my original L4 civilization still has not completely explored the dark side of L2. Energy theory. It doesn’t make much sense to dwell on the level of civilization, and it is impossible for both parties in contact to inform each other of the level of civilization.”

"Generally speaking, you can't judge the strength of the opponent's spacecraft by its appearance...unless you actually fight with the opponent!"

"There are always so many strange things in the universe. Just like the Green Light Civilization, wouldn't it beat up the more powerful Destroyer Civilization?"

"Being vigilant, humble, friendly, and keeping distance are the rules of survival among interstellar civilizations!"

Yu Yifeng was silent for a while, but this was more useful information: "What do you think of our civilization? L2... or L4?"

Hei thought for a while: "Theoretically speaking, our L2, L3, and L4 theories have all scratched the surface, and all disciplines are developing simultaneously. This phenomenon is very rare. So I dare say that before L4, we There’s not much of a bottleneck.”

"But in terms of industrial strength and combat effectiveness, we are probably at the lower reaches of the L2 level. We are better than the L1 that has just entered the interstellar world, but not as good as the old L2 civilization."

"We have too few spaceships. If the Deep Space is destroyed, we will have nothing. Captain Yu... we still need to build ships quickly!"

Facing Hei's loud appeal, Yu Yifeng also had some thoughts in his heart. He planned to specifically supervise industrial issues.

There are thousands of small spacecraft mounted outside the Deep Space, and there is no problem at all.

The development of large weapons must also be implemented as soon as possible.

He finally asked with some reluctance: "...Is there really no other technology in your core memory?"

Hei spread his hands and said with some regret: "I'm sorry, it is gone. My core memory is not complete..."

"Actually, these seemingly epoch-making scientific papers are part of our basic popular courses."

"Just like the new human civilization has popularized the theory of relativity and calculus in higher education, my previous civilization has also popularized more advanced knowledge, so I can use it..."

"I just learned a little bit and can barely remember it. As for superconducting material technology, it is my higher education graduation thesis... Isn't it very good..." Hei said proudly.

Yu Yifeng was secretly stunned when he heard it. He was really drunk that the popularization of basic knowledge had given mankind such a great inspiration.

He thought for a while and realized that he had finished asking questions. He waved his hand to indicate that he had nothing else to ask.

Heiye nodded towards Yu Yifeng and said goodbye politely...

"It seems that this black one is indeed standing on the side of human beings... It still makes sense that we didn't break the contract and kill it."

After watching him leave, Yu Yifeng carefully savored the information about the universe given by Hei.

Human beings are still not strong now, and things like L4 and L5 are too far away. The high-level scientific papers that make mankind ecstatic are actually just some popularization of knowledge...

The gap between civilizations is really huge.

But if you think about it carefully, this statement actually makes some sense. If a normal college student were to travel back in time to Newton's era, he would have enough knowledge to scare the scientists of that time to death!

Even this college student didn’t need to know much. Just a little knowledge of calculus, chemistry or biology would have greatly inspired the scientists at that time!

Let's put it this way, as long as this college student can memorize "Hydrogen Helium Lithium Beryllium Boron..." or can calculate the simplest calculus. This group of scientific elites will naturally be affected by the huge atmosphere and continue along this path, and then it will have nothing to do with college students.

Creating knowledge is always more difficult than learning knowledge, and opening up a road is even more difficult.

Just the theory of dark matter discovered by humans, there is still a lot to explore...

The gene dynamics and brain topology given by Hei are even more vast and boundless, and are just equivalent to a framework. Humanity has just explored an edge and gained a lot, and even invented such epoch-making things as brain chips...

Hei has given mankind a good start, and the rest of the content needs to be filled in slowly by mankind.

In this way, the gap between interstellar civilizations is indeed very huge.

It's a long road... When thinking about the giant creatures that have existed for millions or hundreds of millions of years, Yu Yifeng can't imagine what they will develop into.

Of course, the road still has to be walked step by step.

At this moment, although humans are not the strongest civilization in the galaxy, they are already a rare interstellar civilization. Yu Yifeng will definitely not blindly worry about things.

So many low-level civilizations are still living well, not to mention the new human civilization...
