A trace of pink left the remaining night by the day, and the brilliant sun rose happily and solemnly beyond the crushed gray clouds.

So a series of golden light spots lined up the creation of the alien star, and the gorgeous golden light was inlaid on the edge of the metal, making the whole body extremely brilliant. Occasionally, the particles emitted radiate fluorescently, like statues of a saint in an ancient church.

In terms of visual effects, light reminds people of robots that played heroes or saviors that were popular in the early 2000s and last century.

"But the more beautiful things are, the more they will deceive people."

Jue Hui was dismissed and looked solemn. She turned her head and saw a large number of photographers taking photos. She also saw reporters trying to report in real time, but was quickly controlled by TPC.

It is indeed a humanoid object with limbs and even facial features that look like humans. Its tone is bright and transcendent, such as white clouds, breeze and return. As for the wings spread behind it, it is integrated with organic and inorganic, with a bit of mottled and dreamy colors.

mystery.

Facing the mystery, the unmanned machinery arranged in the human world makes a clattering sound, three are high in the sky, six are seven in the surrounding area, and E00 standing here in all directions.

——

"So how should we face the creatures in this world?"

Facing the same unknown world, I heard Tieria's question in a daze.

The ELS Qan's cockpit quickly panoramic the entire circle, sending all information from all directions into the eyes of the driver.

The fields, strange rocks, sparse trees, speeding drones, clear sky, and blockade lines farther and people farther away.

In the southwest direction, the thermal sensing of the living body is particularly dense. Through the observation of the equipment, it can be guessed that it is a whole temporary military camp and everything is ready.

“They look like humans.”

He said, shaking his head again.

"The first is to analyze the sound and image."

Languages ​​that rely on sound or text to spread, whether in pronunciation or spelling, can obtain simple grammatical rules or language structures (how each unit in a language system is encoded). This is a very violent mathematical statistical method, which is effective for most linear languages ​​with strong logic. After completion, it will be much easier to start cracking semantics.

Although it can be communicated through the brain quantum waves, it is not necessary. In ignorance, it is expected to avoid excessive behavior in a moment. As for the release of GN units for detection, it is also rejected due to contact problems. The third is the interference and intrusion of radio waves, but this area seems to be deliberately blocked outside the signals of the civilized world.

I can understand the collected audio in an instant.

Ordinary Chinese and American English are mixed with Japanese, French, etc., and the same degree is more than 98% similar to the language of the same name in his hometown.

The life image of the main civilizations on the surface of this planet is exactly the same as that of the humans familiar to Shina.

"But also consider the possibility of illusion and deception, or although the audio is the same, the meaning and connotation of its reference are not the same."

Just like the cuckoo's cry, it is considered [cuckoo] in farmers, that is, the meaning of cutting wheat and planting grains, but it is considered a desolate and sad sound in literati. As for the cuckoo itself, it is just for courtship.

People are always accustomed to ideological leaps and connections, which is essential and occasionally hinders.

"The complexity of human language is very high, and it is hard to imagine that it is a coincidence to this extent... but it is not impossible if it is an illusion and simulation."

Faced with everything unknown across the universe, these two people are not afraid to be as cautious as possible.

Love everyone, but trust only a few.

In an instant, I soon saw a new unmanned machine (tentative) approaching carefully, and it had a large speaker... and then I heard the music in an instant.

Three solemn and solemn chords are set from E flat major, followed by a series of lively quick-pitched violin playing, which is next to the exquisite fugue passage, from the tone to the painting, clear and bright, and wait until the end, soft and quiet, fascinating.

"This is the overture of the opera "The Magic Flute" written by Mozart!"

ELS Qan was in a moment of trance.

The Magic Flute is Mozart's most outstanding opera, and its music was selected into the gold record carried by Voyager One (an unmanned outer space solar system space probe launched in 1977).

The sound produced by the mechanical vibration of an object, as a vibration state, is a very ordinary phenomenon in the universe. Therefore, it is difficult to imagine that unknown higher creatures know nothing about mechanical waves; but at the same time, the many different meanings contained in mechanical waves are also difficult to imagine that they can be understood by aliens.

Even so, the rhythm of music is more believed to resonate among different species than hundreds of ordinary communication languages ​​in humans.

If you want to be closer to the common language of the universe than music—

That's only physics and mathematics.

The former is a truth that is closer to the universe itself than music.

The latter is the truth that can be independent of the universe and is still free and permanent.

Sure enough, a box popped up on the screen, showing that ELS Qan received a series of pulses.

In addition, I saw a row of symbol tables projected in front of me.

However, the numbers inside are not Arabic numerals, there are only six large symbols, and a series of equations are given to illustrate the relationship.

The instant guess corresponds to 1 and 0, greater than, addition and equal to.

On the one hand, Tieria quickly obtained the pulse analysis results.

"I guess it's binary code. If converted into commonly used decimal numbers, it's roughly 2, 3, 5, 7, 11, 13, 17, 19... In other words, that is..."

He said that word carefully:

"Prime number."

Humans on this planet are carefully sending a series of prime numbers and trying to establish the correspondence between prime numbers and symbols.

A prime number is a natural number that can only be divided by one and itself in a natural number greater than one. This means that the prime number distribution will not be covered by any other real number distribution to obtain any other distribution rules.

It is particularly noteworthy that so far, I have never heard of any astrophysical process (whether it is a quasar, pulsar, or radio galaxy) that will generate a series of waves that express prime numbers in sequence.

This means that the distribution of prime numbers is a truth that is sufficient to distinguish between civilization and non-existence throughout the universe, and it is also the key to building a common mathematical language.

Building a common mathematical language is the first step, followed by physical language, chemical language, biological language... step by step, and then advance from scientific language to daily language to complete thorough communication and communication.

He instantly conveyed his thoughts to Tieria and said:

"They should have thought so, so they deliberately sent prime numbers to test us?"

Tieria nodded.

"So how should we respond?"

Asked instantly.

Tieria on the screen frowned.

"Send them the final rule of prime distribution?"

Prime numbers are like unruly rocks in natural numbers. The scientific community once thought that there was no law in the distribution of prime numbers (people cannot accurately predict where the next prime number exists). But in fact, after solving the Goldbach conjecture and Riemann conjecture one after another, the final law of prime number distribution was finally captured by humans, as the biggest progress in the mathematics community in the 23rd century in the hometown of Shina.

Note: Relying on Veda to a great extent.

In addition, this law can automatically generate a graph called a prime helix, so this law is also called the prime helix law.

The wind outside was quiet, and the magic flute overture had been played. They were next to Tchakrulo (Georgian folk chorus), and one minute later, the traditional Inca musical instruments of the Inca people were played.

This is probably a parallel earth.

Looking out in an instant.

The projection is still changing, and the pulses are beginning to show more different expressions.

People on this planet seem to be using pure mathematics to express the inverse squared law. (If the distribution or intensity of a physical quantity decreases according to the inverse square of the far and near the source, it is called the inverse squared law. For example, both Coulomb forces and universal gravity abide by or are a inverse squared law.)

"Why are they so skilled? It's like they have rehearsed countless times." I immediately checked the dormant record before it was fully activated and became confused. "It seems that they have actively tried many communication and detection just as ELS Qan arrived."

"Maybe there are a lot of alien civilizations in this universe?"

Tieria gives a possible answer.

In the unknown world, everything is unknown.

The sun is wandering, the wind comes and the grass is waving, everything seems to be as beautiful as his hometown.

But are there many terrifying secrets hidden in it?

“If we really want to respond to this communication using information such as the law of distribution of prime numbers, how do we send it?”

"Well, direct projection, how about?"

The young man nodded.

His hand was touched in the air, and the body went with the will.

In the air ten meters above the ground, cyan fluorescence emits, creating a media-free aerial imaging.

"What is that?"

Dr. Serizawa showed a shocked face.

"It seems to be a dot matrix."

Harry Shetton, chair of the Department of Mathematics at Miskatonick University, was recruited and appointed by the TPC this year and was responsible for the compilation of the third part of seed engineering [Abnormal Encyclopedia].

Now, more TPC staff arrived at the front line and were waiting for the abnormal movement of E00. There were few people everywhere, so he was happy and stared at the complex dot matrix.

One line, two lines, three lines, four lines, four lines, no matter which side is from the upper, lower, left and right, it is exactly the same.

Starting from the center, one point after another gradually brightens, and the same circle of unlit points becomes dark at the same time, and then a huge vortex shape is formed, like a lotus blooming layer by layer, and Zhou Luo is incomplete in its secrets.

"This is a prime number spiral! It is responding to our signal!"

He immediately saw it and shouted.

In addition to the constantly expanding spiral, there are words that are used to communicate with the universe depicted by pulses and projections in basic mathematical language (end to calculus and sets)! These words gradually series of beautiful formulas, written in several dense pages, and casting eight screens.
