Wandering planet that will travel

Of course, its role is not limited to that. Many people have noticed that in the 45 billion-year-long ancient memory of the earth, there have been more than one visits from alien civilizations.

Even before the birth of life, there were creations from outer space that fell down, but were buried deep in the rock formations, and trying to find them was like looking for a needle in a haystack.

This is no accident, since it has been proved that human beings are not alone in the universe.With so many alien creations scattered in space, in the 45 billion years, even if they are only rare, some of them will fall on the earth.

Originally, it was almost impossible to find these things without being able to determine the original location.

And things that fell on the earth hundreds of millions or even billions of years ago are now buried under rock formations that are unknown.

It is not a super project like an earth tunnel, and it will never be dug to such a deep place, so the chance of digging it out by accident is close to zero.

But now with the guidance of the will of the earth, all this is not a problem.The coalition government immediately mobilized personnel to go to the site where the meteorite had fallen, and re-excavate these treasures that had been buried on the earth for hundreds of millions of years.

This is undoubtedly a valuable property given to mankind by the will of the earth. The earth with such a long history has accumulated wealth beyond human imagination.

Soon, one alien creation after another was unearthed like fossils.These are all things that have fallen on the earth for billions of years, and now they are all cultural relics who don't know how long ago.

Most of the stuff has been damaged beyond recognition, and if it weren't for the will of the earth as a guarantee, it might not know that it actually came from outer space.

In fact, not much information can be read from it, because the more precise something is, the easier it is to be damaged. For example, modern quantum memory can hold the materials of a large library with only one grain of rice. It has been preserved for about 2000 years, and after 2000 years, nothing can be read because of the decay of the internal materials.

U disks and hard disks are a little behind. If these memories are of good quality, they can store information for about 5000 years.Especially old-fashioned optical discs, if made of special metal materials, can reliably store information for 10 years.

But these are not as good as printed matter, good quality printed matter, using special synthetic paper and ink, can still be read after 20 years.But that's the end of it, and there's really no guarantee for a longer period of time.

So these things may have been created by advanced alien technology, but after being buried for hundreds of millions of years, they have become fossils now, and it is difficult to find any useful information.

However, there are exceptions to everything. Among these ancient cultural relics, only one is a complete cultural relic.

It was a black obelisk, and there was no aura from outer space in its shape. There was no sense of disobedience in saying that it was a local cultural relic of the earth.

But in terms of geological time, this obelisk fell on the earth about 30 billion years ago. At that time, even dinosaurs had not yet been born, let alone a cultural relic left by humans.

What is even more bizarre is that when the dust on the obelisk was cleaned and its original appearance was restored, the investigators used an ordinary ruler to measure the three sides of the obelisk, and the length ratio was 1:3:9.

In the future, no matter what more accurate method is used to measure, the ratio of the three sides of the obelisk is still accurate 1:3:9, without any error.

This is enough to prove that this black obelisk is special, and it is by no means something that can be manufactured casually. It may be a bit difficult with the current technology of Wandering Earth.

As for its method of preserving information for hundreds of millions of years, it is both full of primitiveness and the only feasible method known to mankind, that is——

Carve words in stone!

Chapter 7 The Golden Ratio and the Decimal System

The Central Academy of Sciences immediately conducted a comprehensive analysis and research on this black obelisk. Although the language on it is not any existing human language, it has many similarities with hieroglyphics in terms of structural logic.

Many linguists have pointed out that it feels like interpreting classical Chinese. A short sentence contains a huge amount of information, but the final interpretation is still a poem full of artistic sense, so it is essentially a piece of history. cultural relics.

The most specific information is only human biological information, so specific that a human embryo can be cultivated based on the data.

But when this obelisk fell on the earth, it was still at the beginning of life, and human beings would not appear until 30 billion years later. How did this obelisk record human biological information?

All of this makes people feel unbelievable. Where did this black obelisk come from?

To be honest, the moment he saw this obelisk, Qiao Lv had roughly guessed the origin of this cultural relic.There is no doubt that it is the human cultural relic in the collection of Li Bai Wenming mentioned by the system administrator.

As for how it ended up on the earth, it may be a good thing done by the system, just like the wandering earth's crossing.

But after the spiritual world came back, the system stopped responding, as if it had completely disappeared.

So Qiao Lv had no way of knowing how to interpret this black obelisk, and just knowing its origin was of no use.

Scientists are naturally full of interest in this black obelisk. Among other things, the ratio of the three sides of the obelisk is absolutely precise 1:3:9. up.

Ding Yi is of course very enthusiastic about it. He knows how difficult the so-called absolute precision is, so he knows that this is not an ordinary cultural relic, and its technological content is not as simple as a stone.

The material of the obelisk is also surprising. Generally, no matter what is buried in the ground for billions of years, it has long been eroded into disrepair, and the words engraved on it should also be smoothed.

But not only the words on this black obelisk are still clearly visible, but even the proportions of the three sides are kept absolutely accurate. This kind of technology is daunting.

Such a seemingly ordinary stone tablet contains unimaginable craftsmanship, of course Ding Yi will not let it go easily.

Li Yiyi, Ding Yi's student and assistant, also helped with various tests.He was not so enthusiastic about this obelisk, thinking that this is what archaeologists should do.

The biggest focus right now is the ratio of the three sides of the black obelisk. Why did it take so much effort to make it absolutely precise 1:3:9?

In general, things that require absolute precision have special meanings.For example, the international kilogram prototype uses a cylindrical weight made of platinum-iridium alloy to define the standard weight of one kilogram.Even if it is only a few micrograms less, it can no longer be regarded as the standard.

So what is the purpose of maintaining such precision in the ratio of the three sides of this black obelisk?

"Could it be the golden ratio in art? For example, a golden rectangle or something." Li Yiyi asked.

艺术上确实有黄金比例的说法，具体上是(√5-1)/2的无理数，可以约等于0.618：1，就像圆周率一般取3.14一样。

This ratio is considered the most aesthetically pleasing and is used extensively in art.A rectangle with a ratio of 0.618:1 is known as the golden rectangle, and many architects design according to this ratio.

Considering that the front of this black obelisk is also a rectangle, and the poems full of artistic sense are engraved on it, it is natural to think of the golden ratio.

毕竟0.618：1只是人类文明的黄金比例，谁也说不准某个外星文明的黄金比例会不会是1:3:9，审美这种东西是很难说的。

Ding Yi shook her head and said, "Then do you know how the golden ratio came about?"

"Golden section, divide a line segment into two parts, so that the ratio of one part to the total length is equal to the ratio of the other part to this part. The ratio is the same as its reciprocal. The reciprocal of 1.618 is 0.618, and 1.618: 1 and 1 :0.618 is the same."

Li Yiyi's basic knowledge is still very solid, of course, this question will not trouble him.

Ding Yi lectured: "So for you, learning without thinking is useless. Since you know that the golden ratio is related to mathematics, why do you think it's just an aesthetic problem?"

Although the golden ratio is commonly used in art, it is still a mathematical method at its root.

Its appearance solves many mathematical problems, such as dividing a circle into ten equal parts, dividing it into five equal parts, finding the sine and cosine values ​​of 18 degrees and 36 degrees, etc. It is by no means a purely aesthetic problem.

"The so-called beauty must follow a certain law, and art and mathematics are inseparable. Otherwise, why does everyone who learns to paint have to learn geometry? Don't you even understand this?"

Li Yiyi was so taught by Ding Yi that he couldn't hold his head up. He still thought things too easily.

"Then teacher, do you think that this obelisk is made in such a precise proportion to convey some kind of information?" Li Yiyi asked.

Ding Yi raised her head and said: "The most direct guess is that it wants to tell us that the ratio of something is 1:3:9. It may be some kind of formula, which means too much."

For example, from decaying uranium to fission atomic bombs, to the nuclear fusion of the sun, to the annihilation of matter and antimatter, all follow a short formula: E=mc2.

If this is indeed some kind of formula, its effect may be unimaginable.Just as the golden ratio above has many uses in mathematics, a simple ratio has the potential to change everything.

At this time, the linguists responsible for interpreting the poems on the obelisk also made a major discovery, that is, whenever numbers are involved, the poems use the decimal system.

Don't take it for granted that the universal use of decimals is simply a consequence of the biological fact that the vast majority of people are born with 10 fingers.
