The wait of more than half a month was too painful, and people suddenly felt that the speed of light was really too slow, and it took more than ten days to go back and forth......

During this time, there was a frenzy of research on the "Dark Forest Theory" in the Noah's spacecraft, and people wanted to study the "Dark Forest Theory" and find its loopholes to estimate the possibility of human war with extraterrestrial civilizations.

"There are many prerequisites for the Dark Forest Theory, including the chain of suspicion, that destruction is easier than communication, technological explosion, and world-destroying weapons. But I think the key lies in the sparseness of interstellar civilizations! ”

In the largest forest park of the Noah, a group of people are sitting in a circle on the lawn. Overhead is a light that resembles sunlight, and under your feet are grass and some insects.

In the past few days, because of the shutdown of a large number of laboratories, they can only "unwillingly" take a vacation. A lot of energy and industry have been freed up to make nuclear weapons.

The middle-aged man at the front of the lecture is a cosmologist. Beside him was a blackboard with a large number of images and the results of the relevant derivations. He pointed to the blackboard and continued: "If interstellar civilizations are sparse and scarce, there is no need for wars between civilizations for survival resources......"

"According to our common sense on the planet, all nation-to-nation confrontations involve a fundamental concept, and that is interests. Benefits can be traced not only to the state, but also to the entire civilization. If the benefits of a war are less than the losses caused by the battle, then there is a high probability that the war will not occur. ”

The people below nodded as if they didn't understand, and one of the girls suddenly stood up: "Teacher, I have an opinion......

"We don't know each other's social structure, we don't know each other's moral system, if the other side is a war maniac or an irrational species," she said...... Uh, like, the Zerg? Then the possibility of war is very high. ”

People have had a lot of fantasies about the entire universe, and although it is very unlikely that something irrational can cross the stars, who knows if the universe is so big? Maybe there is?

The cosmologist nodded and said, "Yes, you're right, so we're ramping up the creation of nuclear weapons just in case......"

There is too little time for development, the technical level of human beings is still quite limited, and the technology of space weapons such as electromagnetic guns and lasers is not mature, so the best way at present is to manufacture thermonuclear weapons in large quantities. Nuclear bombs are slow and easy to intercept, but humanity has no choice. The more people produce, the more secure they feel in their hearts, whether they are ordinary people or senior leaders.

Yu Yifeng stood in the Kinov Industrial Factory, watching the nuclear bombs being manufactured in batches, some of which were deuterium-tritium hydrogen bombs and some helium-3 bombs.

Of course, there are more atomic bombs, and the last thing that mankind lacks is uranium resources, which can be dismantled if they are not used.

"It's still too short, if only it would be a few more years old......"

He kept lamenting that there was not enough time, that it was too sudden, too inexplicable, and that there was really not enough time......

According to his thoughts, there are three that could lead to war.

First, the other party is a madman civilization that explodes at the slightest touch, and the other party may think that the human behavior of firing artillery is a sign of active attack, and will take the initiative to return fire in order to protect themselves. Or that the other party saw the flaws of the human race and knew that the combat power of the human race was less than five scum.

Second, the other party is a perverted civilization, a war maniac, and destroying other civilizations will gain great spiritual satisfaction. After all, the universe is so big that there are no wonders, and no one knows if there really is such a perverted civilization......

Third, there may be inexplicable benefits to the elimination of other civilizations, such as luck, and so on...... This statement is a bit fantastical, but there is no way for human beings to rule it out, after all, human beings know too little about the universe.

Too little information is really a headache, and no matter how smart scientists are, they can't come up with a better solution. All the steps people do now are according to the highest probability of success, but the premise is that the universe is not a dark forest, and ...... The other party is not the civilization where the Martian flying saucer is located.

If this extraterrestrial civilization has a logic similar to that of humans, or any animal on Earth, and knows how to pursue advantages and avoid disadvantages, the possibility of war breaking out is very small.

"I hope they aren't perverted ......civilizations that explode at the slightest provocation," Yu Yifeng muttered as he looked at the batches of nuclear bombs. Even if the fish dies and the net is broken, let them know that humans are not easy to mess with......

As time passed, people's hearts became more and more nervous. Scientists are constantly staring at the observation instruments. The sun's rays were too sparse and reflected too dim, making it difficult to find the ship with a normal telescope.

According to common sense, if this alien civilization is deliberately hidden, humans will not be able to find it at all. However, it emits a huge amount of heat at all times, so the alien spacecraft can be easily spotted with a thermal imaging telescope!

"This huge amount of heat may be emitted by the engine...... But it shouldn't be, even if the universe isn't a dark forest, it doesn't have to be so blatant, right? ”

Physicist Dr. Rimbaud gestured puzzled as he said, "This source of heat is too undeserved, like a nuclear bomb explosion...... Could it be that they also use the power of a nuclear bomb to propel the ship? ”

Rimbaud is a scientist that Yu Yifeng admires very much, he is young, and his mind is very active, as if he is wild. He always gets to the heart of the problem where people don't expect it.

"No way, we didn't find a flash of a nuclear bomb explosion." Yu Yifeng shook his head and said: "And relying on the propulsion of nuclear bombs, the energy conversion rate is too low, and it is impossible to accelerate the spacecraft to 0.4 times the speed of light......"

Rimbaud nodded, "You're right...... But I didn't mean that, I always felt that the other party's behavior was very strange, and it could have been more hidden, but it seemed to be at a loss, not at all as sophisticated as I imagined. ”

"The interstellar civilization should be very powerful, very developed, and much more advanced than our technology...... Shouldn't it? Even the other side even let us detect the radio signal, which is very undeserved. Even if the universe is not a dark forest, there is no need to be so sloppy if civilizations can develop peacefully between civilizations, right? ”

"What do you mean?" Yu Yifeng wondered.

Rimbaud was hot-headed, a little excited, and spoke faster and faster: "There are two possibilities, first, they are rookies who have just stepped into the interstellar civilization!" Maybe they don't know if the universe is a dark forest......"

"Second, the opposing ship's ship may have been damaged. The ship was in a dilapidated state, and there were constant leaks...... They rushed into the solar system in a panic to replenish energy and supplies! ”

"In either case, the other side will not dare to start a war easily, it will be beneficial to us humans! Our camouflage plan can most likely scare them, and even squeeze a little oil! ”

When Yu Yifeng heard this, he suddenly stood up, his back felt cold, and he had to be shocked by Rimbaud's crazy idea: not only to intimidate the other party, but also to blackmail the other party......

He paced back and forth, constantly pondering the feasibility of this "blackmail" statement.

No, it's too risky, there is no shortage of science and technology in human beings, nor is there a shortage of research directions, what is lacking is only time. He still has to be cautious, no matter how cautious he is, he can't be rash and greedy!

“…… Our telescopes will be able to spot that ship in a few more days, and we'll make a decision then! ”

No matter what, you must first know the other party's attitude...... If you really fight, and you still blackmail a fart? Yu Yifeng patted his head, and he also felt that he was a little nervous, and he really thought too much......
