Everyone's hope was extinguished in an instant, but they were still very unwilling. General Gant must have known the answer long ago. His questions must have been asked many times in the past

"Please explain!" general Gantt said calmly.

Alien Ike paused, as if organizing language: "in terms of quality, the civilizations existing in the universe can be divided into two categories: one is kind and peace loving.

The other is belligerent and keen on aggression and expansion

We can assume that your distress signal is received by one of the alien civilizations and we know your existence. Then, if the warlike race receives your distress signal, the result may be worse than now, just like a victim who is being robbed of his wallet and calls another gang of murderous robbers... "

"What if a peace loving race like you received it? Wouldn't we have another way out?" Hao Zhi asked unconvinced.

"No, pacifists don't mind their own business!" the Sequoia wise man shook his head and smiled.

"That's bullshit peace loving? Watching us killed and abused but indifferent?" Hao Zhi scolded in a low voice.

EK helplessly stood up: "this is the attitude of 'pacifist civilization' in the universe. If you participate in wherever there is war in the name of maintaining peace, then the races that fight the most in the universe are those who claim peace, aren't they?

In the universe, there is no such concept as "weeding out the strong and supporting the weak" or "walking on behalf of heaven". It is easy to imagine that when you humans shoot a field documentary, when you face a lion hunting antelope, will you not participate in it to save the seemingly pitiable antelope?

Because of what happens naturally, no one will interfere. You saved the antelope, preached your 'Peace' and 'justice', but starved the lion. Isn't the lion innocent?

Moreover, if "peace" can be a reason to launch or participate in war, there will be no real pacifists. Real pacifists only observe the universe and let things happen, that's all.

Similarly, if we want to investigate the "reason", the so-called war nation can also invade the world weaker than itself in the name of "loving peace". Even if it is just for the survival of the animals on earth, or to prevent you from killing each other, so that you will no longer continue to destroy the natural environment, it can be a reason.

War is only the needs of individual civilization. In fact, there is no so-called justice and evil. You used to look at problems from the perspective of human centered thinking. If you stand from the perspective of blood moon people, their efforts to continue their race can also be regarded as a "just" act.

Moreover, the cost of participating in a permanent interstellar war is almost exhausting all the resources of a civilized galaxy. Who will help you fight a war that has nothing to do with him?

Is it just for the praise of a 'pacifist' in your mouth?

The real advanced civilization doesn't care what others think of itself. Everything can only rely on you people on earth to solve the problems you face... "

"Ghost theory!" Hao Zhipi curled his lips and stopped talking.

"Can you provide some information about the aliens who invaded us?

For so long, we know nothing about the enemy, which makes us always in a passive situation on the battlefield! "General Gantt reluctantly changed the topic.

"Sorry, I know nothing about the alien civilization you are facing

There are too many forms of civilization in the universe, just like

As like as two peas of the famous philosopher Leibniz once said, there are two leaves that are not identical in the world.

There are no two identical snowflakes in the world. Have you heard of this theory?

In terms of scientific structure, each snow crystal contains 1018 water molecules. When these water molecules fall from the air at different temperatures, pressures, geographical environments, and even in the crystallization process, different random flight trajectories and angles will cause these water molecules to randomly combine into a snowflake.

The probability of two identical biological civilizations is almost the same as the process of snowflake formation, which is difficult to encounter.

They may have a great degree of similarity, but there will be great differences in specific forms. This difference itself is the bottom information of each civilization itself. This information is extremely key and has been made the "secret key of civilization".

The secret key of civilization is a double-edged sword. It hides its biological characteristics and is a bottom card against other races. For example, if alien races know your general information, such as carbon based organisms, adapt to survive between minus 30 degrees and above 50 degrees, take carbon water compounds as the food source, take water as the basic condition of life cycle, and so on.

The alien race who knows this information can decide whether it is necessary to invade your world based on this information. "

"Why? Why does this information become the key?" Wang Yanke said he didn't understand. "Isn't a galaxy rich in resources and pleasant environment the first choice to be attacked?"

Sequoia wise man EK smiled happily: "resources are everywhere in the universe. Most civilizations that can carry out constant interstellar navigation do not lack resources, which can be obtained everywhere.

The second thing you said is that a pleasant environment suitable for the development of civilization is the key to the self-development of all civilized races.

But the question is... Who set this standard when the environment is suitable?

I know that you humans have the following description of a planet's good environment: in the right position from the star, there is liquid water, the temperature is between 30 degrees Celsius and minus 30 degrees Celsius, there is a solid planet's surface, soil and plants, and so on

But this is the result of your view of the universe centered on human beings themselves.

Let's take a simple example. Regardless of such a big gap between the eternal stars, from the earth:

Tropical fish may be difficult to survive hundreds of kilometers away. Deep sea fish will die in shallow water. If you expand it, fish and land creatures can't understand each other's living environment. Land creatures drown in the water, and vice versa.

There is a small shrimp in the volcanic community at the bottom of the Atlantic Ocean. It has long lived near the erupting submarine volcano, where the sea water is boiling. The volcano constantly spews out a large amount of sulfur and nitric acid to dissolve in the sea water. In the strong acid and boiling sea water, that is its "livable environment". If you move it to the bathtub in a warm room, it will be "frozen to death", Maybe it will say, how can we live without high concentration of sulfur and acid in the water?

If the main body of the earth civilization is this kind of shrimp, if they become a high-level intelligent civilization, when exploring the alien world and looking for a new environment that can be immigrated, those standards formulated by your human beings may be completely abandoned, right?

On the other hand, if aliens are such shrimps, when they see the environment in which people on earth live, they may also feel that it stinks, or even "extremely bad", and has no value of aggression at all.

You know, this is just a comparison of life formed in the environment of a planet as small as the earth. If it is two civilized worlds separated by a few light-years or even hundreds of light-years, the difference between the civilized biological groups developed by them is certainly much greater than that between the two pieces of snow after the different conditions encountered on the road of evolution for millions of years The difference between flowers.

There are too many random factors, which will inevitably lead to the living environment and biological differences between the two civilizations. Among them, the individuals are large enough to be like a planet, while the small ones are even equivalent to viruses. Some life is carbon based, and some life can be silicon-based. Some aliens are even gaseous, liquid, or even plasma, or only It is an energy light mass, as elusive as the "ghost" described by your human beings. Some life forms may be just an energy flow, an electrical signal with high intelligence characteristics.

Such a huge difference in civilization forms, coupled with the huge cost of interstellar navigation, aggression and war are almost impossible.

It's like you humans have penetrated millions of light-years of the universe with super large radio telescopes, and you haven't even found a fierce star war going on?

The universe is not a cold God, but a kind mother. It gives life enough luxurious living space and endless energy, so that they can live in peace and develop independently. There is no need to war with each other.

Therefore, the secret key of civilization is not only a wind vane of civilization aggression, but also a safety lock for civilization self-protection. It will be protected by a civilization and will never be known to the outside world. It will not be easily spied among advanced civilizations. Therefore, we know nothing about the blood moon civilization invading your planet.

However, from the point of view that the other side can conduct interstellar navigation, their civilization has been ahead of the earth people for more than 1000 years! And they have mastered the secret key of your Earth people's civilization. You have the value of being invaded by them! "

"Since you know nothing, how do you judge that the other party is at least a thousand years ahead of our civilization?" Wang Yanke came out of the team and looked directly at Ike's deep eyes.

The wise man EK smiled mysteriously, stroked the flowing silver beard in front of his chest, and looked at his head. In the virtual picture, the top of the whole warehouse became a dark and deep cosmic starry sky:

"To understand this problem, first of all, you should understand what civilization itself is?

Is it books, paintings, hymns or historical documents?

No, it's just a carrier for recording civilization!

The development of civilization and science and technology is actually the change of walking mode!

Think back to your human history. From the primitive society, apes landed on all fours. In their eyes, the world is a tree to another tree.

They wandered and jumped in what they thought was "incomparably open" jungle, until one day, one of the apes finally came to a tree outside the forest, and the world it had recognized came to an end.

At this time, it peeled off the leaves and suddenly appeared in front of the vast land, mountains and rivers, which stunned him

This has brought a leap in the cognition of this ape. It turns out that the world can still be such a big grassland!

So he began to crawl clumsily on the vast grassland. Later, he found that occasionally standing up would be more convenient and run faster.

So, slowly, apes began to stand up and run more and become people. People measured the world with their own feet and liberated the hands that can be made. Finally, one day, these primitive people came to the beach

So, another cognitive leap came.

It turns out that the world is not only a vast grassland, but also a sea hundreds and thousands of times larger than the grassland land!

They began to try with their own intelligent hands, made simple rafts, crossed canyons, bays and even oceans, arrived at a new world, and began the development of communication and civilization.

Later, they learned to nomadize, plant and domesticate horses. The emergence of this natural means of transportation doubled the longest distance an ape can walk in his life, so that he can collect all the food in the range that he couldn't walk in the past three days in one day, which promoted the acquisition of resources and doubled the space for civilized activities.

Later, mankind invented ships, cars and airplanes... From the space shuttle to the space capsule. Every reform of the mode of navigation will lead you to see a wider world and recognize more truth, which will drive the sustainable development of civilization. "

Wang Yanke couldn't help interrupting and asked, "you mean that the essence of civilization in the universe is to find more unknown fields and see a wider range of unknowns. In front of other civilizations in the universe, it is also carried out according to this law?"

EK nodded and confirmed her guess!

"The so-called civilization is the way you can see the world! No matter what kind of civilized creature you are, the direction of civilization development is fixed, that is walking!

Go where you haven't seen, see things you haven't seen, until you find the true face of the universe!

In order to facilitate your understanding, I will use the expression and enumeration methods you are most familiar with:

The first-class civilization in the universe, that is, the civilization that has mastered the navigation ability at the speed of light and above.

They are races that can freely cross time and space on an eternal scale, from one end of the universe to the other, or from the end of the universe to the birth of the universe.

According to your human understanding and habits, we call him "divine civilization", which is higher than all other civilizations.

They do not worry about any aggression at all, nor do they disdain to invade others, because they have become so strong that no enemy can surpass them. Under such a prerequisite, the war will end together, so no one will take the initiative to start a war.

Moreover, when science and technology develop to the end, the only purpose of the existence of divine civilization is to carry out philosophical thinking and discover the truth of the universe itself.

I don't expect you to understand what civilization is doing at this level. Perhaps from your point of view, they are more like a bunch of madmen, always carrying out endless ideological experiments and attempts of self destruction.

To reach that level of civilization, the survival of the universe does not seem to have much to do with him. Even if the universe is over, they can still exist outside the universe... "

"Jump out of the three realms, not in the five elements?" Wang Yanke whispered.

"The second civilization can be called" fairy civilization ".

They haven't mastered the ultimate mystery of the universe, but they already have technology close to divine civilization.

This kind of civilization basically has the navigation ability of one tenth of the speed of light. It can sail from one end of the parent galaxy to the other end in a relatively short time, and can also sail freely across galaxies. It can freely use the energy of a "quasar" to serve itself, whether it is building a new world or destroying the enemy. "

"Quasars?" Hao Zhi touched Wang Yanke and said he didn't know.

Wang Yanke explained to him in a low voice: "it is an interstellar body in the universe. A small planet has greater energy and brightness than all stars in the whole galaxy combined!"

EK was not upset that he was interrupted. He patiently waited for Wang Yanke to finish talking before continuing to introduce him.

"The race that has reached this civilization level has long abandoned the original model of fixed planet development, and there will never be a shortage of resources. They wander among various galaxies in the universe, pursue the ultimate development of science and technology and the leap of civilization, and are keen to learn knowledge and transform civilization itself.

In the eyes of immortal civilization, all the resources of a planet add up to the brightness of a match

Therefore, they do not want to invade your home and live there, and they disdain to take the poor resources in your home. Therefore, fairy civilization will not carry out meaningless aggression. Unless it is provoked and self-defense, it is possible to launch a war. "

"Obviously, the blood moon is not in this line!" Wang Yanke exchanged eyes with general Gantt and continued to listen.

"The third level civilization, that is, the 'magic level civilization'.

Civilization at this level has highly developed science and technology, but it is also in the bottleneck period of civilization development. They have just stepped out of their own star system and basically mastered the navigation ability at the speed of light.

Therefore, they can travel between stars, but the speed is slow and the consumption is huge. It is impossible to cross the whole galaxy.

From a star to a star, they often need thousands of years of voyage, so they must exploit the stellar resources with huge energy for their next stage of navigation.

Once there are other civilizations around the stars they encounter in their mining, especially when this newly developed civilization that is still shrinking on its own parent star is far lower than their science and technology, the disaster is often devastating.

They will drain the resources of a star and then fly away. Weak and small civilizations can only watch the star that provides energy for themselves collapse, expand, and then slowly extinguish, silently die in the cradle and become cannon fodder on the road of the development of each other's civilization. "

"These aliens who invaded us should be demon civilization?" Hao Zhi asked.

EK shook his head: "no, the blood moon is far from the level of demon civilization. They can only be regarded as demon civilization at most.

This level of civilization, like those monsters in the ancient myths and legends of your human civilization, has good and evil. Some basic demonic abilities, eat people and harm others, or help others, are just a dream.

There are many kinds of Civilizations at this level, and the number is also the largest. They have the navigation ability of about one thousandth of the speed of light, and can only navigate within the stellar system very close to themselves.

Once beyond this range, it will lead to unpowered interstellar drift due to midway energy loss. After losing energy driving force, it may take hundreds of thousands or even millions of years to reach the next star that can collect resources. Long before that, the civilization itself on the Starfleet may have been extinct and turned into cosmic residue.

Therefore, at this stage of demon civilization, unless there is a depletion of parent star resources or major changes, they generally will not rashly leave their parent galaxy or even invade others.

Because the voyage takes too long and there are too many unpredictable factors in the middle, it is possible that in the hundreds of years since he flew to the weak civilization, the weak civilization has developed to the magic level or even the fairy level, and the result can only be moths to the fire. "

Hao Zhi suddenly asked curiously, "what level does our human civilization belong to now?"

EK smiled contemptuously, "what is the fastest speed of your human aircraft?"

Wang Yanke thought for a moment and replied, "the fastest man-made aircraft in the world should be the 'new horizon' probe launched in 2006. Its fastest speed has reached nearly 60000 kilometers per hour..."

EK laughed: "in other words, it's only one 20000 times the speed of light, barely reaching the level of 'human civilization'. Your human civilization is still toddler..."

Hao Zhi was unconvinced and wanted to ask for psychological comfort: "is there anything lower?"

It can be classified as "animal civilization" or "reptile civilization". Please note that the navigation speed of all civilizations I just mentioned refers to the premise that the use of large star fleet can carry out ethnic migration on a planetary scale.

Launching small exploration satellites is not included.

If you measure human beings by this standard, you are far from being out of the level of reptilian civilization
