The Science Fiction World of Xueba

Chapter 196 Questions and Answers

The edge of the solar system, the periphery of the Oort Nebula.

A moon-sized interstellar battleship moored silently in the void.

Inside the bridge, the captain is communicating with the fleet commander a thousand light-years away through the intelligence field.

"Your Excellency, the target galaxy 500921473 has discovered a self-evolving civilization, and it has passed the first-level civilization test."

said the captain.

"I didn't expect that in this desolate and empty place, there is still a first-level civilization that evolved independently. This area is really too open, and the density of stars exceeds two hundred cubic light-years. If there is no cultivation of advanced civilizations and sufficient resources , They will be imprisoned in sub-light speed and three-dimensional space-time for two thousand years, and it will take at least one thousand years to master and use the annihilation energy. After two thousand years, they will be able to communicate through multi-dimensional space-time. As for space travel through hyperspace transitions, it is possible It will be five thousand years later, and it will take at least ten thousand years before they have the minimum conditions to join the family of carbon-based civilizations in the Milky Way.”

The commander said with some emotion.

The captain said: "Your Excellency, Commander, will this planet be included in the civilization cultivation and expansion plan of the Carbon-based Life Alliance in the Milky Way?"

"Ship Blue 84210, you go to this galaxy immediately to conduct a full-surface civilization inspection on planet 3. The mission in front of your ship will be taken over by other ships. As for whether it will be included in the cultivation plan, we will wait for the inspection results to come out."

"Understood... Hey, what's going on?"

In the computer, the sudden information sent the captain's intelligence field into chaos.

The commander seemed to sense the captain's strangeness, and asked, "Captain, is there any problem?"

The captain seemed to be still in a state of shock: "Your Excellency, there seems to be a problem with our ship's computer system. A digital replica is sending us information. Of course, it may also be caused by a computer system failure."

The commander was slightly taken aback, and said, "Synchronize the computer system data of the blue 84210 ship."

In the next second, Pang Xuelin's voice appeared on the bridge of the flagship a thousand light-years away.

"Excuse me, can I answer the test questions for the second-level civilization?"

Inside the flagship, the atmosphere suddenly became tense.

A digital replica, as the name suggests, is just a memory replica of a biological body, and it is impossible to have self-awareness.

But now, this clone from a first-level civilization not only possesses self-awareness, but even vaguely perceives the existence of the Milky Way Hegemony-level alliance.

This is a bit scary.

The fleet commander turned his attention to the scientific staff officer.

The scientific staff is conducting a comprehensive screening of the computer data in the Blue 84210 ship. After a while, the scientific staff said: "Your Excellency, the computer data is normal."

The commander's intelligence field fluctuated violently.

No abnormality?

yet feel their presence.

Could it be that behind this first-level civilization, there is still a super civilization that has never appeared before?

"Agree to his request and give him the second-level civilization test questions."

At this time, the intelligence field fluctuations of the Chief Executive Officer of the Carbon-based Life Alliance, which received relevant information through high-dimensional space-time synchronization, appeared in the flagship bridge.

"yes!"

The commander hesitated for a moment, and immediately replied.

...

Inside the digital void.

Pang Xuelin stood there calmly.

He figured at least five minutes had passed.

Although they haven't received a reply from the other party, but this digital space has not been closed, it can only show that the Carbon-based Life Alliance has received the message they sent, at least they don't seem to have figured out how to deal with it internally.

"Will they agree to their request?"

Pang Xuelin was thoughtful.

According to the previous civilization level test questions, the earth should be in the appearance of a first-level civilization. If the other party agrees to tell me the second-level civilization test questions, even if I can't answer them, I can still find the future direction of technological development for human civilization.

Even going one step further, through them to obtain more information about alien civilizations, even though there are certain differences in the laws of each plane, it also has a very high reference value for traveling in various science fiction planes in the future.

At this time, in the digital void, the ethereal voice sounded again.

"Tier 2 Civilization Test Question No. 1: May I ask whether the thinking activities of carbon-based organisms are at the neuron level, the molecular level, or the quantum level?"

Pang Xuelin's eyes lit up all of a sudden, and he said, "Quantum level?"

This question is a multiple-choice question, but its answer may have a very significant impact on the direction of human brain science research in the future.

"Test Question No. 1 passed, Level 2 Civilization Test Question No. 2: Please briefly explain the mechanism of gravity."

"..."

Pang Xuelin frowned.

There was a question: "If you chased a beam of light, what would it look like? Would you not see a wave of light at rest, frozen in time?"

At the age of 16, Einstein discovered that there seemed to be nothing in the world that could catch up with the speed of light. At the age of 26, he proved this discovery with rigorous mathematics. As a junior clerk at the Swiss Patent Office, he used Maxwell's field equations to derive special relativity.

To sum it up in one sentence, that is: the speed of light is always constant in any perpetual structure.

This theorem is not obvious on the surface, but it is indeed one of the greatest achievements in the history of human civilization!

Speed ​​of light is constant, time slows down, quality is not constant, "mass-energy" mutual transformation e=mc.

This is the whole derivation process of the special theory of relativity, which unifies "space-time" and "mass-energy".

After unifying "space-time" and "mass-energy", Einstein further thought about the relationship between "space-time" and "mass-energy", that is, the acceleration and gravity ignored by the special theory of relativity.

Thus came the general theory of relativity.

Or start with a simple question.

"If a man is in free fall, doesn't he feel his own weight?"

Einstein grasped the basic properties of gravity through this simple problem: the laws of nature under the framework of acceleration are the same as the laws of the gravitational field. This is the so-called equivalence principle.

Through the principle of equivalence, Einstein reconsidered the issue of the speed of light: the speed of light is affected by gravity, and the gravitational field distorts the path of light.

However, according to Fermat’s shortest time principle, light will take the shortest time path between two points, and Einstein once again came to a shocking conclusion: if we can observe that light advances in a curve, it means that space itself is Curvy!

It is further concluded that the existence of mass-energy causes the curvature of the surrounding space-time.

But until now, the physics community still has no clear answer, whether the existence of gravity leads to the curvature of space-time, or the curvature of space-time produces gravity.

According to the inference of quantum mechanics, there should be a boson with a spin of 2 and a mass of zero, which is the legendary graviton.

However, when calculating gravitons, it is found that there is a large error between the theoretical calculation results of gravitons and the actual situation.

Therefore, until now, the physics community has still not been able to give a clear answer to the mechanism of gravity generation.

Pang Xuelin blinked and said, "The curvature of space-time produces gravity?"

"Wrong answer."

Pang Xuelin smiled, this reply was unexpected.

However, if the generation of gravity has nothing to do with the curvature of space-time, then it can only be explained that the existence of gravity has caused the curvature of space-time.

The corners of Pang Xuelin's mouth curled up slightly.

"Level 2 Civilization Test Question No. 3: Please briefly describe the basic structure of the Sagittarius A black hole."

"..."

Pang Xuelin was speechless.

Sagittarius a is a black hole in the center of the galaxy. At present, with the level of astronomical observation of the earth, there is no way to effectively observe Sagittarius a.

"pass!"

"Tier 2 Civilization Test Question No. 3: Please give the exact mathematical model of the sun."

"..."

"pass!"

"Tier 2 Civilization Test Question No. 4: Please give a map of the distribution of mineral resources in the solar system."

"..."

"pass!"

...

Pang Xuelin was speechless. The next dozen questions were either astronomical questions beyond human observation and exploration capabilities, or various questions beyond the scope of human scientific research.

Pang Xuelin has never heard of many concepts.

Soon, Pang Xuelin realized that the other party might have guessed his thoughts, so he used this method to hide some scientific and technological information with high strategic value.

After the fifteenth question was over, Pang Xuelin said: "Forget it, terminate the second-level civilization test program, I want to see you. You almost destroyed the solar system in order to build the Great Wall of Stars, and you brought me here, You have to give me an explanation."

The digital space is quiet again.

This time, the other party's reaction came faster than Pang Xuelin imagined.

About a minute later, in front of Pang Xuelin, an old man with a human image suddenly appeared.

The old man stepped forward and waved lightly.

Soon, a table and two rattan chairs appeared in the space.

There were even two cups of steaming green tea on the table.

"Mr. Pang Xuelin, hello, I am the Chief Executive Officer of the Galactic Carbon-based Life Alliance. In your language, I should be called Maiwi Shamabu Kodas Drakell."

"I'll call you Your Excellency the Consul, hello! Just now you said my name accurately, you should have investigated my identity information on Earth, right?"

The consul nodded and said: "Mr. Pang, first of all, I would like to express my apologies to you. In order to prevent the silicon-based alliance from counterattacking, we had to destroy a large number of stars in this area. But since it has been confirmed that there is a first-level civilization on the earth, we will not Destroy the solar system, but this star field will be included in the protected area, and the higher civilizations of the outside world are strictly prohibited from entering."

As he spoke, the old man said again: "Mr. Pang, let's sit down and talk."

Pang Xuelin smiled, sat down opposite the old man, picked up the teacup on the table and took a sip. The tea was rich in aroma, basically no different from the taste of green tea drunk on earth.
