After Li Hao finished writing his advice to the country, he looked at the information that the parrot had translated.

When he saw a certain piece of information, the pupils of his eyes dilated, and a look of surprise appeared on his face.

Pick up this material immediately and read it carefully.

The content of this material is very simple, it is the introduction of economic civilization transactions. As a currency to measure the value of an item.

It is only after the advent of money that trading goes into a boom.

From the perspective of the history of the earth's civilization, the development of trade has mostly changed from the barter stage to the currency transaction stage.

The trade between interstellar civilizations must not be carried out by bartering.

Because the whole trading plate is too large, the value of the things traded is different for each civilization.

Bartering will definitely cause civilization to feel at a loss. It can't be carried out for a long time, and in the end it is only kept in a small trading circle, and it cannot be expanded.

It is unlikely that it will dominate the entire trading market and survive for a long time.

Transactions between civilizations must be guaranteed by monetary value and, as far as possible, to the satisfaction of all civilizations.

As a currency used between interstellar civilizations, it must go through a long period of collision and fusion.

Judging from the development of the various civilization systems on the earth, money was generally a product of high value in the early stage.

For example, in ancient times, the ancestors believed that shells were of high value. Just use shells as currency.

With the development of civilization, especially the improvement of smelting technology.

It has been found that copper, silver, gold and other metals have the characteristics of stable properties, scarce reserves, and exquisite appearance.

They are generally used as a currency for trade to measure the value of all items.

Now we have entered the age of credit, where the value of money is guaranteed by the credit of the state.

But between interstellar civilizations, credit currency is certainly not available. After all, the Alliance of Stars is not able to overwhelm all civilizations and adopt his currency. Not to mention credit money.

The universal currency of the stars is matter and energy.

It is measured by standard energy, and one serving of standard energy can support a minute of sub-light speed.

It is roughly equivalent to the total electricity consumption of the whole country in China in a day.

But almost all civilizations that have entered the interstellar age have mastered nuclear fusion technology or gravitational power generation technology.

They have access to very cheap energy.

Therefore, except for the energy block that has been compressed with high strength, it has trading value, and other energy sources have no trading value.

The energy inside an energy block can be used for a year's worth of sub-light flight, and it occupies a very small space.

The most important thing is that the energy can be fully exported in an instant, which is very adaptable. It is mainly used as an energy source for interstellar weapons.

The reason why standard energy is used as a measure of money.

It is because it has a very simple value assessment.

No matter what civilization it is, as long as it enters the interstellar age, it is exposed to sub-light speed flight.

We all know the energy consumed by flying for a period of time, and the value it has.

Marked with standard energy, no matter what kind of interstellar civilization it is.

He can easily judge the value of various substances, and there will be no misunderstandings caused by cognitive biases, which is convenient for various civilizations to carry out trading activities.

When Li Hao saw this explanation, he smiled heartily.

This setting is the law formed by various civilizations in the interstellar world through long-term exploration.

Not to say that this setting is the most perfect, but it is the most acceptable to everyone.

Li Hao continued to check what was the ordinary currency used when trading interstellar civilizations?

After reading it, he was taken aback. Ordinary money turns out to be a pure element.

This pure element must be isolated from its isotopes and not adulterated with other substances.

Their value fluctuates greatly, with the cheapest being hydrogen and helium. The most expensive turned out to be metals such as gold and lead.

Li Hao is very strange about the reason for this situation? If we rank their value according to the number of nuclear power cores, it should be that the further back they are, the greater their value.

It can be used as a nuclear fission element, uranium, which is not as valuable as carbon. This really surprised him.

What is the standard of value measurement between extraterrestrial civilizations that leads to such a big difference between them and other people's knowledge.

Li Hao looked at the information of the interstellar pirates in detail. to figure out why this is happening.

Because hydrogen, helium and other elements are widely present in the universe, as long as you enter the civilization of the interstellar age. All they need is a couple of spaceships plus a trawl.

These resources can be obtained in large quantities, resulting in very low value of these resources.

The value of the elements is indeed ranked according to the number of nuclear cores in the periodic table.

Because of the change in the number of nuclear cores, it has a great relationship with the generation of elements.

The higher the number of nuclear charges, the more difficult the conditions to develop. The lower their storage in the universe.

The rarer the thing, the higher the value, and this eternal and unchanging truth is also valid in the universe.

Most elements are formed by fission or fusion.

Most of the stable elements in the universe are formed more through fusion.

Iron is a transition element, and fusion produces elements with fewer cores than iron in nuclear power, and when a nuclear fusion reaction occurs, a large amount of energy is released.

Fusion produces elements with more nuclear charges than iron, and when it undergoes a nuclear fusion reaction, it absorbs a lot of energy.

So elements with more nuclear charges than iron are only generated in the center of the star.

That is, all elements that have more nuclear cores than iron are the remains of stars.

It is because of such extreme living conditions that the higher the number of nuclear charges. Their total mass in the universe is very scarce and more valuable than other elements.

In addition to the number of nuclear power cores, there is another important condition for measuring the value of an element, which is stability.

Li Hao looked at the detailed information and said that only stable elements can be deeply processed into various equipment.

It also has a very long storage time and can be stored for more than tens of thousands of years without deterioration.

The stability of an element depends on whether its nuclear force restraint is strong.

In other words, whether the element is radioactive or not.

Any element that is radioactive is not a stable element, and the value of this element in the universe is extremely low.

After Li Hao read the detailed introduction, he finally understood what the currency between the civilizations of the universe was.

In cosmic transactions, large transactions are usually made with energy blocks. The value of one energy block is equal to 550,000 standard energy.

The value of one hundred kilograms of pure lead metal is equal to the value of 100 kilograms of pure gold metal is equal to one standard energy.

Li Hao was extremely happy when he saw this value exchange ratio.

In the early stages, the exchange value of metals for alien civilizations was very different from that of human civilizations.

Even if he is a master of the exchange rate, he can mix well.

But Li Hao's ambition is not so low-level, and the thing he is most happy about is that human civilization can take out interstellar currency and purchase all kinds of materials.

Only when the money in his hand can be spent, he will generate the greatest value.

The most painful thing is to have a lot of money in your hands, but you can't buy what you need. Luckily, it didn't happen.
