“………… Your loyal neighbor, Sidney civilization. Pen %Fun %Pavilion www.biquge.info"

Noah quietly finished reading the message.

This message is very informative, not only detailing the various flora and fauna living on the planet, but also part of the history and customs of the Sidneys who rule the planet.

The main thing is that, as if to deter the other party, the civilization level of the star Sidney and the armaments of the various countries above have also become the focus of the introduction.

The other party has only just been involved in nuclear energy, and it is not as good as the earth civilization at the end of the 20th century, but the other party has already reached a point where even Noah is surprised by the use of basic chemical energy.

Due to the completion of the initial controlled nuclear fusion at the end of the 21st century, the use and development of basic chemical energy has gradually been phased out, and this Sidneyan civilization has obviously worked a lot of hard work on top of it, in addition to fossil energy such as crude oil and coal, they have developed a set of energy systems that can efficiently produce and utilize methane.

Methane, on the other hand, is one of the most efficient and environmentally friendly sources of basic chemical energy.

Noah estimates that according to the technology mentioned in this information, the comprehensive civilization level of this civilization is probably comparable to that of the earth civilization from the beginning of the 21st century to the middle of the 21st century.

Even the mode of thinking is similar to that of the earth civilization of that era.

At the end of the 20th century and the beginning of the 21st century, the earth civilization was also keen to send radio signals to extraterrestrial civilizations, but in the middle of the 21st century, due to the views on the cosmic environment involved in some literary works, it was believed that the universe was a dark forest, and the civilization should hide itself before it became strong to a certain extent, otherwise it would attract powerful predators to plunder. Such theories gradually aroused people's thinking, and the craze for extraterrestrial civilization contact activities gradually faded.

This civilization doesn't seem to think about it that much, and they are really lucky, because the message they send is really received by the alien civilization.

In Noah's consideration, the degree of civilization of the Sidenia civilization is obviously not able to communicate with the light grade, and it should use the radio wave amplification effect of the star, so Noah receives radio wave information......

And through the time difference between the probes around the Centaur galaxy receiving information, Noah can roughly determine the direction of the source of the information.

It was pointing to the solar system, deflecting about 13 to 15 degrees towards the Andromeda river system.

In that direction, there are tens of thousands of star systems, but if you take into account the extreme distance of radio communication, it is impossible for the other party to transmit communication hundreds of light-years away.

In the tens of light-years in this direction, there are only a few galaxies that have planets in the habitable zone of stars, and then we remove the galaxies that have been proven impossible to have intelligent life......

Gliese 581 Galaxy!

The name of a galaxy popped up from Noah's logical thinking.

Gliese 581 is a Draconi BY variable star located in the constellation Libra and is about 4.3 billion years old. The mass is 0.31 solar mass, the radius is 0.38 solar radius, the brightness is 0.013 solar luminosity, and the surface temperature is about 3480K......

It is a star much smaller than the Sun and younger than the Sun, but according to the law that the more massive stars in the universe have shorter lifetimes, this star will live longer than the Sun.

The galaxy has observed six planets, among which Gliese 581d was once one of the "16 super-Earths outside the system" praised by the astronomical community, and Gliese 581d and HD85512b are the only planets that have evidence that are suitable for human survival.

The Gliese 581 galaxy is located 20.4 light-years from the solar system and 24 light-years from the Centaur α galaxy.

A stable galactic environment, a rudimentary level of civilization, not too far away, and a large number of intelligent life............

It's like saying to Noah......

"We have a lot of resources! We have a large population! We're still pretty unbeaten! And we're right on your doorstep! If you don't rob us, you're a pig! Or a pig with dementia! ”

"............-Noah"

Human beings are inherently a warlike race, and looking back on the history of mankind is a history of war, and Noah, who inherited everything from human beings, naturally inherited this nature.

Unlike the solar system, which has a supercivilization like the Kara civilization, this galaxy is quite backward in terms of civilization, and since the current state of the star Gliese 581 is far more stable than that of the Sun, Noah can even get more time to develop there, and most importantly, it has at least six planets!

Six planets, not to mention whether there are any rare resources buried on these planets, the energy that the six planets can provide to Noah in the fusion of heavy elements alone is an almost infinite number......

However, prey that is too good can also be dangerous, as in ancient times, when hunters caught their prey, placing a smaller, defenseless prey in a trap to lure another, larger prey into the trap......

Let's not talk about whether this Sidneyan civilization really exists, and by Noah's side, there is an even more powerful predator.

Kara civilization!

In Noah's logical thinking, the Kara civilization has no reason to be hostile to him for the time being, but there is a gap in the degree of civilization, and Noah cannot logically determine his relationship with the Kara civilization 100%, if this weak Sidenia civilization is the prey fabricated by the Kara civilization in order to capture Noah, what will happen?

Even if the current Noah expands his armaments, the war with the Kara civilization will definitely be at a disadvantage, but since Noah has also mastered the near-light speed vehicle, as long as the Kara civilization does not create a real faster-than-light vehicle and steps into the realm of the Type II civilization, then they can't do anything with Noah.

Take 10,000 steps back and say, even if this civilization that has knelt down in front of the girl and begged for training without fear of tigers really exists, and they are really in the Gliese 581 galaxy, then according to the direction and position, the Kara civilization guarding the solar system obviously received this information before himself, if the Kara civilization is also interested in this galaxy, then there is nothing to do with Noah.

However, in the past on Earth, there was such a theory - the monkey's banana theory.

A human living in a modern city, living a worry-free and self-sufficient life, suddenly one day learned that in the forest outside the city, there is a monkey living happily, this human, will go to the suburbs to catch this monkey, just to snatch the banana in its hand?

The Kara civilization has such a resource-rich place as the solar system, and although their level of civilization is very high, it is not so high that even the entire solar system cannot meet their resource expenses, and according to logical deduction, they will probably not be interested in this low-level civilization. Unlike Noah, Noah is like a lone traveler in the desert who sees an oasis that even if the oasis is thousands of miles away and there are monkeys occupying the water source, Noah will come there and throw the monkeys out.

But the perceptual thinking of life cannot be explained by logic, just like the human countries in ancient times, when the territory was large enough and the resources were enough, they still couldn't help but invade other countries. This is also the core of the conflict between the two theories of [Monkey's Banana] and [Dark Forest].

How the Kara civilization will deal with this civilization is also one of the important criteria for Noah's next move.

But no matter what, Noah didn't plan to act as if he hadn't seen anything, and an investigation was still necessary.

It just so happens that the interstellar probe on the schedule some time ago has completed the model construction, and Noah plans to launch a probe to the Gliese 581 galaxy in the near future.

See if it's a trap with great seduction, or a fat sheep exposed to a tiger and a hungry wolf, or a Thanksgiving turkey already on Noah's table......
