Milky Way, Dutar (Cygnus). Pen % fun % Pavilion www.biquge.info

After Yuan Haochen and the others left the Dark Energy Civilization's phalange observation station in the red dwarf galaxy, they converged with the main fleet of the expeditionary force at the fastest speed.

At this time, the expeditionary fleet's journey was nearing its end, and it was less than 900 light-years away from the Dutar Black Hole (X-1 Cygnus). According to the chart given by the phalange observatory, the other three observatories of the dark civilization are 234.5 light-years, 589.3 light-years, and 771.1 light-years away from the expeditionary fleet, respectively.

In addition, the star system of the primary planetary civilization mentioned by the head of the Phalanges Observatory is still 159.2 light-years away from the expeditionary fleet. Based on the average speed of the expeditionary fleet, it will take at least 16 years to reach the system where the cosmic civilization is located.

The road is long, I will go up and down and seek. Seeing that the black hole of Dutar was getting closer and closer, the hearts of the expeditionary force became more and more difficult to press.

Psychologically, the more you get to your destination, the slower you feel.

It is no wonder that the ancients once said: Those who travel a hundred miles are half ninety. Sometimes, the last ten miles are psychologically equivalent to the ninety kilometers ahead.

.......

As before, all members of the Expeditionary Force are on rotational duty, and when they are not on duty, they go into a dormant state to slow down the flow of life as much as possible, so as to ensure that the veteran members of the Expeditionary Force can at least make it to the Dutar Black Hole alive and complete their scientific missions.

Because, in the last leg of the trip, the expeditionary force had already learned the general situation on the route from the observation post of the dark energy civilization, so Yuan Haochen increased the number of dormant people in the same period to 70% of the total number of members of the expeditionary force.

However, Yuan Haochen has always insisted on his job, and the reason why this is so, in the final analysis, is because his life span is far beyond ordinary people and can withstand squandering. As a result, a long time has been quietly spent in scientific research projects, the exploration of strange galaxies or other cosmic celestial bodies along the way.

The expeditionary force's journey of thousands of light years is in itself a major harvest and scientific achievement.

Compared with human civilization, which once cowered in a corner of the universe, this expedition has greatly expanded the horizons of mankind and deepened their understanding of the universe. Along the way, the expeditionary force has observed nearly 16,000 stars at close range, and more than 300 star systems have flown or traversed, counting the unknown primary planetary cosmic civilization and dark energy civilization in front of them, a total of 4 extraterrestrial civilizations have been dealt with.

From this, Yuan Haochen preliminarily deduced that although human beings are not alone in this vast universe, the density of cosmic civilizations is indeed not high, and the number of galaxies that each cosmic civilization can dominate is still extremely large.

Of course, this result does not match the fact that the universe was born more than 10 billion years ago. And it is this mismatch that further corroborates the inference that those advanced civilizations born in the galaxy have left one after another and gone to outer space.

However, in general, it is not easy to give birth to every life form in the universe.

Life has a variety of different forms, and different life forms have very different requirements for the living environment, which is a heavenly environment for one life, and may be like hell for another life. For example, the living environment of the ancient Guding civilization and human beings are heaven and hell for each other.

It was also difficult to find other intelligent beings, but the expeditionary force had accumulated some experience along the way.

There are a few conclusions that, at least in the current cosmic environment, are instructive. Although there are special circumstances, planets with intelligent beings generally meet these conditions.

First, there is a living star system, and the star must be in a stable state and be able to output enough energy stably and peacefully for a long time. Some supergiants, stars in the early days of life, and stars that become red giants in old age, are too chaotic inside the galaxy because of the intense stellar activity. will easily strangle life in the cradle.

Second, the lifespan of the star must be long enough. The lifespan of a short-lived star like a blue supergiant star is simply fleeting on a large scale of cosmic time, and it is absolutely impossible to provide sufficient time conditions for the slow evolution and growth of living things.

Third, living things are generally born, reproduced, and evolved on planets (there may be life on stars, but humans have not yet discovered this). So, some lonely star system with no planets, or a multi-star system, will not be the cradle of life.

Along the way, the expeditionary team's scientific team explored and studied a variety of star systems and saw various forms of planets, which was really eye-opening and worthwhile.

"I wonder if there will be creatures in this universe that use gaseous matter as a carrier for the exchange of matter and energy? After all, theoretically, it is also possible for gaseous substances to do this. ”

So far, the cosmic creatures that Yuan Haochen has seen are all organisms that exchange energy and matter in the body using liquid matter in different temperature environments as carriers.

"The life forms of nucleic acids/proteins mediated by water are indeed the mainstream of life forms in the universe. However, no one can answer the question of what kind of life forms will exist beyond imagination. Yuan Haochen pondered.

The expeditionary force will soon arrive at the star system where the primary planetary civilization mentioned by the Knuckle Observatory is located, and Yuan Haochen is becoming more and more curious about what kind of cosmic civilization humanity will encounter next.

......

On this day, the rotating deputy commander of science, Lola, knocked on the door of Yuan Chen's office.

"Leader, the observations of the star system ahead are out."

"Please show me." Yuan Haochen put down the work at hand and walked to the center of the office.

"Please wait."

Lola replied as she began to operate the holographic simulation presentation system.

Soon, the light in the office began to dim, and a dazzling star appeared in the very center, radiating a dazzling glow. Immediately after that, the three planets also appeared in sequence and orbited the star according to a certain pattern.

"The star is about 1.1 times the size of the star's sun, and the light intensity is 18.1% higher." Laura began to give Yuan Chen this detailed introduction, "If other asteroids are not counted, there are a total of 3 planets and 7 moons with large masses. ”

"Of these 3 planets, there are 2 gas planets and only one rocky planet. Two of the gas planets are very far from the star, and the rocky planets are very close to the star......"

Yuan Haochen stared at the star system for a while, and then said, "These three planets, including all the moons, are in an extreme environment. ”

"Yes, but according to the description of the dark energy civilization, there is indeed a rudimentary stellar civilization within this star system."

Laura is also well aware that the environment in which these three planets are located is either freezing or scorching hot. In the eyes of human civilization, it is really not an ideal place to live.

However, since the Dark Civilization has said that there is a rudimentary planetary civilization here, the life form of this unknown civilization should be quite different.

"Lola, do you guess if they are an iron-blooded civilization (a molten metal environment in life) or an ice-blooded civilization?" Yuan Haochen asked.

"Judging from the situation of these three planets, I think the possibility of an iron-blooded civilization will be higher and more interesting."

Lola guessed with interest.

"Then let's wait and see." Yuan Haochen said with a smile.

PS: Today's work task is very heavy, so there is only one change, please understand, thank you for your support.
