Chapter 402

High level civilizations observe and even keep low-level civilizations in captivity, such as watching ants.

This is an idea with a strong local market.

After such ideas have been spread through forums, literary works, film and television works and some games, their popularity has reached a very high level.

For example, the famous "three bodies" describes things related to extraterrestrial civilization.

For this reason, it is not surprising that academician pan would think of the possibility of captivity.

Then academician pan paused and continued:

"In the final analysis, we still have relatively limited information.

Observation or breeding.

This is just our guess. At present, we have no evidence to support this.

It can't even be ruled out that the previous civilization just passed by like a passer-by, leaving some marks.

Like a passenger on a green train, he accidentally dropped a candy when the train was running.

This matter is irrelevant to passengers, but for roadside ants, it is a big news that can attract the attention of the whole population.

Therefore, at present, the only thing we can simply judge is that the kardashov index of the leading civilization is at least 1.8. "

Kardashov index.

As the name suggests, it is the index put forward by a man named kardashov.

This man is from the hairy bear next door. He put forward this theory on May 15, 1964.

Yes, it's such a coincidence - on the 42nd anniversary of Yuewen group.

Cough

get down to business.

According to kardashov's classification, civilization in the universe can be divided into three levels:

Ⅰ、Ⅱ、Ⅲ。

Type I civilization can use all the energy on the parent satellite, including satellites.

For the earth, it is the moon above us.

Type II civilization can collect the energy of the whole stellar system. For us, it is to fully control the output of the sun.

Type III civilization can use the energy of the whole galaxy, that is, the Milky way where we are now.

According to the power standard of type I civilization of kardashov civilization index.

The input energy calculation of the earth needs to reach 1.74e17 watts, that is, 1740000000000 watt hours, in order to be regarded as type I civilization.

Later, Carl Sagan set the standard to 1e16 watts and set a formula to calculate the civilization level when it failed to meet the standard:

K=log(10 × P-610。

Where k is the civilization level index and P is the total power of civilization.

The current power of the earth is 2e13 watts, and a number can be obtained by substituting it into the formula:

0.7301。

This is the source of some popular science or science fiction stories that mention that we are now level 0.7 civilization or level 0.73 civilization.

Later.

Carl Sagan used this formula to redefine type II civilization and type III civilization, and expanded them.

For example, the standard of type IV civilization is the total power of 1e46 watts, the standard of type V civilization is the total power of 1e56 watts, etc

However, most serious people do not discuss type IV civilization in journals, just as serious people do not write diaries.

By the way.

A civilization that outputs one big bang power per second has a kardashov civilization index of 6.35.

Well, every second.

Generally speaking.

The kaldashov civilization index is about 2.8.

The kaldashov civilization index is about 2.9.

For a civilization that controls 10 billion stars, the kardashov civilization index is almost 3.

The civilization index of the famous country of light is almost 3.7, which belongs to a nearly pluralistic civilization. (the calculation method is in the words of the writer)

Yes, of course.

This refers to the situation before the Bei empire,

After the emergence of the Bei Empire, the country of light has collapsed a bit like the combat effectiveness of the dragon ball.

In addition.

According to kardashov's theory.

When the civilization index exceeds 1.5, it is more likely to use or produce some unconventional special energy.

The concept of such energy is broad.

In a sense, Lingshi and Lingqi are also one of this kind of energy.

Therefore, academician pan Jianwei judged that the index of leading civilization in the world of Mozambique is almost more than 1.8.

Please note that.

1.8 here refers to the level of civilization development 2 million years or even earlier.

"1.8..."

Lin Li touched his chin thoughtfully and continued to say to academician Pan:

"Academician pan, let's make a hypothesis.

Assuming that this civilization is still not extinct, what level of civilization may they be now? "

Academician pan was silent for a moment and said:

"It's hard to say. After all, there is a theory called the singularity theory of science and technology.

For example, many local people believe that 2045 will be the time period for the arrival of technological singularity.

At that time, as long as mankind is not exterminated by super artificial intelligence, a huge breakthrough will be made in all aspects.

Theoretically, the leading civilization may also have technical singularity, but if this mutation is not considered

Two million years should be enough for them to break through the index of 2.9 or even 3.0. "

When Lin Li heard the speech, he immediately stopped breathing.

You know.

With a civilization index of 2.9, the number of stars under control is 1 billion!

If this civilization has not been cut off

Rabbits take wool to play with each other!

You can't get 10000 Yan Shuangying and iron man to take the opposite, okay!

Then academician pan changed his painting style and continued:

"However, this is only a theoretical guess. After all, a civilization lasts for 2 million years, and this difficulty is theoretically infinitely close to zero.

Combined with the pictures observed by teacher mingmou and the information of the great Mo world we now have, my personal tendency is

There should be some problems with this advanced civilization.

Maybe migration, maybe fault, maybe extinction.

In short, they must have left the Da Mo world, otherwise they can't explain the current situation of the Da Mo world.

Yes, of course.

If that civilization really has any evil interest in observation, it is no different from directly lifting the table.

It's better to say that we are the characters in a novel. "

Academician Pan's view is very objective. He is not comforting himself or pretending to be an ostrich.

If that leading civilization has not been cut off in the past more than 2 million years, they are now at least k2.9 civilization.

That is, the number of stars mastered by light will not be less than one billion.

In this case.

It is impossible for them to focus on only one planet, and pay attention to it for more than 30000 years, but it is getting worse and worse. They have made a pile of bugs, which is almost the end of the law era.

So there's no accident.

The current Da Mo world should not have much direct intersection with the previous civilization.

But then again, the rabbits can't relax too much.

After all, that advanced civilization has enemies.

If the enemy and the previous civilization perish together or perish in the long river of years, it's easy to say anything.

But if the hostile civilization has not been cut off or left a little inheritance like da Mo world

This is a little thought-provoking.

Then Lin Li thought and said:

"Academician pan, I will report this problem to the local side.

If nothing happens.

Next, the research direction and team of our camp will inevitably shift to exploring the leading civilization.

A civilization that can tamper with natural disasters cannot leave no other information. "

Note:

The country of light is calculated in the writer's words.
