Chapter 239

The glitzers have indeed known the existence of electricity. With some small revelations given by "enlightener civilization", they have the possibility to jump directly from the stone age to the power age.

But unfortunately, this step is very, very difficult.

In 100000 years, countless capable and intelligent people launched attacks again and again, but none of them took this crucial step.

Just because there's no oxygen

When I saw this, the voice of discussion in the conference room suddenly increased. There were doubts and curiosities. Some people even questioned the correctness and reliability of this report.

"No technology? It took so long for them to produce real technology? "

"Are the real technologies given to them by the second group of aliens?"

The professor on the stage gave a meaningful smile, as if anticipating that all of you here would have such a reaction: "ladies and gentlemen, I have a question. If human beings are faced with this dilemma, without oxygen, but with a certain amount of scientific thinking, can they jump directly from the stone age to the electric power age?"

Gradually the crowd became silent and began to think seriously.

“…… It's very difficult. It's incredible. " Captain Zhao, sitting in front of him, shook his head gently.

No oxygen means no natural combustion, which makes the development of science extremely difficult. In this case, it is almost impossible to smelt copper or iron on a large scale.

For human beings, the simplest way of copper and iron smelting is carbon reduction method. At a higher temperature, carbon is used as a reducing agent to carry out oxidation-reduction reaction on metal minerals and smelt metal elements.

But this method requires a very high temperature. For glitzers who do not burn, it is very difficult to reach a high temperature of thousands of degrees

Unless we can find a natural active volcano and use the temperature of the volcano, we can have a little possibility.

But when glitzers encounter a volcano, it's too late to escape. How can they risk their lives to make iron? They don't even know the chemical reaction equation!

So, besides carbon reduction, is there any other way? Of course: electrolysis! Most of the metals can be smelted by electrolysis, but the electrolysis must have electricity first!

In other words, without combustion, it is impossible to enter the bronze age or the black iron age. Their scientific and technological progress can only stay in the stone age, and it is difficult to improve their productivity.

And the development of science is gradual, even if they have a good scientific thinking, but also need experiments to support the proposed point of view.

Science is a methodology. If a viewpoint is put forward, if it is consistent with the experimental results, it can be considered correct for the time being.

If it does not conform to the facts, there is no doubt that this view will be abandoned.

But the question is, how to experiment?

For example, if you want to study biological cells, you have to have a microscope first, right? If you want to have a microscope, you have to learn how to burn glass and make lens, right? But without fire, how to burn glass?

Inventing new experimental tools is no less important for scientific research than putting forward new theories.

There are too many similar difficulties. Even under the guidance of enlightenment civilization, the glitzers have already known that electricity, a magical natural phenomenon, can be transformed into great power. But without iron, copper or even conductor, how can we study electricity?

The scholar sitting in front of Zhang Yuan turned his head and discussed: "in this case, I can think of two ways. The first is to clearly know what electricity is. Just like our group, we have already mastered this knowledge. If we suddenly run to the stone age, we can directly jump technology, bronze and black iron. "

Zhang Yuan shook his head: "no, I don't know for what reason, the enlightenment civilization only told them the existence of electricity, but did not tell them the essence of electricity, let alone electromagnetic induction and other phenomena, so they can only explore blindly in the fog."

"Then, the second plan, with the help of the whole country, puts the priority of electric power research in the first place, and relies on a large number of talents to attack these bottlenecks. They are a planet with low oxygen content. Iron, copper and magnets also exist in nature Depending on these natural materials, it's still a little bit possible. "

"Professor, your statement is too difficult, too idealistic..." Another expert questioned: "it can only be an authoritarian government It is only when the dictator is mad that such an order will be issued. There is no such possibility for a democratic government. The people have long been ousted. "

Listening to these comments, Zhang Yuan sighed: "that is to say, in that case, human beings are likely to be stuck. There is no excuse. When they only know the term electricity, how can they try to study wires, magnets and electromagnetic induction? "

"If we continue to deduce, in the universe, it is very difficult for planets without oxygen to develop real technology? This is really It's strange. "

"I think of another way, bio smelting! The change of life is infinite. On the earth, there are some bacteria that have a good accumulation of soluble metals under high temperature conditions. Maybe the creatures on some planets can smelt metals by themselves? ""The probability is not zero, but it's very low. You can't ask all the creatures on the anaerobic planet to evolve the ability of biological smelting... "

When he came to this conclusion, Zhang Yuan had to sigh about the good luck of mankind.

This condition is really a bit harsh. There must be a few planets with a lot of oxygen. Oxygen is produced by photosynthesis of plants and cannot be born out of thin air. The active chemistry of oxygen means that if it can't be produced continuously, it will react with other substances and be consumed.

Oxygen free planets are the majority.

Because of this, the productivity of the glitzer civilization has been in the stone age. There is no way to separate natural elements chemically, and there is no way to study electric energy physically.

Lightning is the only natural phenomenon related to electricity that they can observe when the wind and rain are strong. Various physical models have been put forward one after another, and some people even gave their lives to touch the lightning!

But what's the point of all this when the tools of production are still stone and wood?

This kind of tragedy and the degree of difficulty can hardly be explained by outsiders

"I don't know, I don't know anything We know nothing about the world, as if there is a layer of darkness over our eyes, obscuring our way forward. We know that electricity exists and that it can exert its magical power. "

"But all the attempts were fruitless..."

This wise man, from youth to middle age, and then to old age, exhausted all his efforts, but achieved nothing. In his diary, he wrote sadly: "damn electricity, what is it What

At this time, the distance from the departure of enlightenment civilization has Thirty thousand years.

At the moment of seeing this passage, it seemed that something hit Zhang Yuan's heartstrings. As a scientific researcher, he often expressed such feelings?

The universe is so merciless that it only needs a little catalyst to block a civilization.

Just because there's no oxygen.

There is no sense of ridicule. Compared with the glitzer civilization, human beings are just a little more lucky. At least they have developed their own technology and penetrated the sporadic truth of the universe.

"Well The technology of earth civilization has been stuck for a long time. Is there something missing that we don't know? "

"Lack of some thinking, or reasons we don't know Or something else... "

The evolution of history continues, not for the will of any life

In the case of long-term fruitless exploration, science has slowly lost its momentum of progress, physics, chemistry, biology and medicine are in a state of great stagnation, and no one is willing to study these things any more.

Mathematics is booming. Because mathematics does not need experimental verification, is not limited to productivity, as long as it is logical.

Year after year, 10000 years after 10000 years

The science and technology tree of glitzer civilization began to produce serious deviation, mathematics was the first, other disciplines were in a mess!

It's a funny thing that happened. Its mathematics level has even surpassed that of human beings! However, the tools used are still the most primitive tools such as stone and wood!
