"The difference?"

Noah was slightly stunned, then thought carefully. Pen, fun, and www.biquge.info

The Kadashev scale serves as a way for humans to measure the technological level of extraterrestrial civilizations. But this scale is only theoretical, and the object it measures, that is, highly evolved civilizations, has no real sample reference in human times, but the significance of this scale is that it considers the energy consumption of entire civilizations from the perspective of the universe.

The Kadashev scale classifies civilizations outside the earth according to the power of the transmitted signal, which is divided into three types, but in the application, because it has been quantified, the types can be infinite.

But the disadvantage of this scale is that it completely relies on the signal transmission power of civilization to judge, but this is not scientific, and the existence of the Dyson sphere is the biggest challenge to this scale.

The output power of a typical star (the sun) is the passing line of a type 2 civilization, but it is not rare for stars in the universe with an output power several times or even hundreds of times that of the sun, and the existence of a Dyson sphere can even make those whose overall civilization level has not reached the level of type 2 civilization obtain an output power that surpasses that of type 2 civilization.

And the Dyson sphere is just a device, it has no restrictions on its use in theory, if a civilization builds a large number of Dyson spheres until all the stars in the entire river system (10^10=10 billion) are installed with the Dyson sphere, then can it be said that the civilization has become a type 3 civilization?

This is undoubtedly a fallacy.

Therefore, it is not advisable to simply rely on external objects to increase its own output power, and in a universe that is in the form of a dark forest society as a whole, it is undoubtedly quite a stupid practice to build a large number of such devices that will expose the existence of civilization in the universe.

Noah thought quietly, and the girl's eyes flashed with a faint blue light, as if she had seen the history of human development.

At the beginning of the 21st century, human beings mainly relied on basic chemical fuels, and the overall civilization level was 0.7.

At the end of the 21st century, there was a breakthrough in controlled nuclear fusion technology, atomic energy rapidly replaced basic chemical energy, and the overall civilization level began to transition to a type 1 civilization.

In the 22nd century, the rapid development of applied technology, the breakthrough of nuclear fusion technology, a large number of times projects have been realized, and the overall civilization level has reached 1.20~1.30 at the end of the century.

In the 23rd century, quantum mechanics and string theory were perfected, the grand unification theory was born, technology exploded, and the overall civilization level reached 1.40 before the gamma era.

After the breakthrough of controllable nuclear fusion technology, the solution of energy problems has enabled a large number of century projects to be carried out, and the progress of the century project has further promoted the development of applied technology, and in the development of applied technology, it has also promoted the improvement of the theoretical level......

A glimmer of possibility emerged from Noah's logical thinking, and the girl said slightly.

"How energy is obtained is the decisive gap between different types of civilizations?"

"Correct."

The inheritance cabin (person) affirmed the girl's answer.

"Energy science and technology is the basic technology in the basic science and technology of the development of any civilization, no civilization can avoid it, because every civilization needs it, so it is the fairest to use it to measure the degree of civilization of the cosmic civilization, the civilization below type 1, if they do not find an energy source beyond fossil fuels, they will never be able to get the output power of a typical planet, this is the technological lock-in brought about by the breakthrough of energy technology, relying on fossil fuels alone, the spacecraft cannot get enough output power, A planetary system is an incomparably vast distance for civilization, and the lack of output power is destined to be unable to accelerate the microscopic particles in the particle accelerator to a speed sufficient to observe the deep collision phenomenon, and the lack of research on the basic structure of the particles is also destined to be too high at the microscopic level, and if the microscopic level does not make a breakthrough, it is impossible to break through the later science and technology. ”

Noah listened quietly to the explanation of the inheritance capsule, and she gradually realized that she had obtained curvature navigation technology, graviton, and grand unified theory, but the overall technology did not get the real reason for the huge development speed brought about by the super technological explosion similar to that of humans in the 23rd century.

Because its main source of energy, like the humans of the 23rd century, is still nuclear fusion, even if it is more advanced than the humans of the 23rd century, I don't know how much more multi-level heavy element fusion, but it is still nuclear fusion, an efficient way to obtain energy that imitates the energy of the stars, it can support the energy supply of the entire type 1 civilization, but it cannot support the type 2 civilization, even the most elementary type 2 civilization.

"Tell me, how do Type 2 civilizations get their energy?"

Noah's thinking was almost at a standstill, and all the girl's attention was focused on the next reply of the inheritance capsule (person), this piece of information was too important, the right direction of development would be more precious than the results, and the right signpost on the path of exploration would be able to erase too much fog and ignorance.

The inheritance cabin (person) was silent for a moment, and seemed a little hesitant to tell Noah this piece of information, because if it pointed out the right direction of development, it might already be regarded as the inheritance of technology.

"Please tell me, I don't need any information about that technology, just tell me its name."

Noah continued to ask, the girl's blue eyes reflected the quietly rotating ball of light in front of her, and under the calm eyes, there was the excitement and pleading of the quiet volcano.

The girl seems to hear the sigh of the inheritance capsule (person).

"The complete conversion of mass to energy is the hallmark of a Type 2 civilization...... I will not answer any more questions about this. ”

Hearing the reply of the inheritance cabin (person), a faint blue light flashed from Noah's eyes, and the girl said subconsciously.

"Annihilation of positive and antimatter?"

"I said I wouldn't answer any more questions about that."

"But there is a logical conflict, the manufacture of antimatter can only be carried out in the particle collision experiment, and this experiment itself requires a huge amount of energy, and even if the ring-star particle collider collides for a thousand years, it is impossible to harvest enough antimatter to become the energy supply of civilization, and the final harvest of antimatter is not proportional to the energy consumed, and there is no way to use it as an energy source!"

"I said I wouldn't answer any more questions about that."

"And antimatter is difficult to preserve, can only be confined in a vacuum environment by magnetic field or inertia, although the annihilation reaction with positive matter will achieve 100% conversion of the mass-energy conservation formula, but its exergonic power is much higher than the stellar fusion reaction, and it is not controllable at all! Will blow everything up! ”

"I said I wouldn't answer any more questions about that."

"Is there any other way to obtain antimatter with low cost and high efficiency? If so, what is the principle? What to do? ”

"Our conversation time isn't eternal, are you sure you want to continue with this?"

The reply from the inheritance capsule (person) made Noah calm down again, and the girl did not continue to ask questions, but a trace of loss flashed in her blue eyes.

"I will only show you the direction, as for how to move in that direction, it is your own business, if I tell you everything, it will go against the original intention of our civilization to start the inheritance."

There was no trace of turbulence in the reply of the inheritance cabin (person), as if he was saying something that was taken for granted, but it was indeed a matter of course, just to tell Noah a correct direction, it was already very precious information, and if he continued to dwell on such an issue, then the inheritance cabin (person) might even reconsider Noah's inheritance qualifications.

The loss in the girl's eyes was quickly faded, of course she could realize all this, but the Type 2 civilization, the field that the Earth civilization had not been able to set foot in for tens of thousands of years, the key technology to reach this field was too tempting, so tempting that Noah could temporarily lose his mind.

The complete conversion of mass to energy is the hallmark of a Type 2 civilization.

Noah remembered this sentence deeply, and the girl shook her head, letting the starry sky behind her hair dance in waves.

"I'm sorry, and thank you for telling me so much."

"No thanks, it's my obligation, and personally, I have a good impression of a rare life like you."

"Hmm...... But is artificial intelligence really so rare? ”

Faced with Noah's question, the inheritance cabin (person) was silent for a moment and said.

"AI isn't rare, but you're not AI."

"What do you mean? I can confirm that I am an artificial intelligence created by humans. ”

"It's a pity that the amount of information transferred between us will reach a limit, and the question of your form of existence will be too complicated to answer, and I can only answer you one more direction, do you want to continue to understand the level of galactic civilization, or your own form of existence?"
