The Gliese people did already know about the existence of electricity, and with some small revelations from the "Enlightener Civilization", it was possible to jump directly from the Stone Age to the Electric Age.

But sadly, this step is very, very difficult.

For a full 100,000 years, countless capable people and wise men have launched attacks again and again, but none of them have taken this crucial step.

Simply because there is no oxygen......

When I saw this, the voices in the conference room were louder, some were skeptical, some were curious, and some were even questioning the correctness and reliability of this report.

"Didn't technology come out? How long has it taken them to come up with real technology? ”

"Could it be that the real technology was given to them by the second batch of aliens!"

The professor on the stage smiled meaningfully, as if he expected the reaction of everyone present: "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 Age. ”

The crowd gradually fell silent and began to think seriously.

“…… It's difficult, it's unbelievably big. Captain Zhao, who was sitting in front, shook his head slightly.

The absence of oxygen means that there is no natural combustion, which makes the development of science extremely difficult, and in this case, it is almost impossible to smelt copper or iron on a large scale.

For human beings, the simplest way to smelt copper and iron is the carbon reduction method, which uses carbon as a reducing agent at a higher temperature to carry out redox reactions on metal minerals to smelt metal elements.

But this method requires very high temperatures, and for the Gliese people, who do not burn, it is no wonder that they want to reach high temperatures of thousands of degrees......

Unless you can find a natural active volcano, the temperature of the volcano can be used to make the slightest possibility.

But when the Gliese people encountered a volcano and it was too late to escape, how could they risk their lives to make iron? They don't even know the so-called chemical reaction equations!

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

In other words, without the phenomenon of combustion, it is impossible to enter the Bronze or Black Iron Age, and their scientific and technological progress can only stay in the Stone Age, and it is difficult to improve productivity.

The development of science is gradual, and even if they already have a relatively good scientific thinking, they need experiments to support the ideas they propose.

Science is a methodology, and after a point is presented, if it is consistent with the results of the experiment, then the point of view can be considered correct for the time being.

If it does not correspond to the facts, this view will undoubtedly be discarded.

But the question is, how to experiment?

As a simple example, if you want to study biological cells, you need to have a microscope, right? If you want to own a microscope, you have to learn how to burn glass and make lenses, right? But if there is no fire, how can you burn glass?

The invention of new experimental tools is no less important for scientific research than the formulation of new theories.

There are too many such difficulties, even if the Gliese people, under the guidance of the enlightener civilization, already know that the magical natural phenomenon of "electricity" exists, which can be converted into great power. But there is no iron, no copper, not even conductors, how can we study electricity?

The scholar sitting in front of Zhang Yuan turned his head and discussed: "In this case, there are two ways I can think of, the first is to know clearly what electricity is all about. Just like our group of people, who have already mastered this knowledge, if they suddenly run to the Stone Age, they can directly jump technology, skip bronze and black iron. ”

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

"Then, the second plan, with the strength of the whole country, puts the priority of power research in the first place, and relies on a large number of talents to impact these bottlenecks. They are low in oxygen on this planet, and iron, copper, magnets, and elements also exist in nature...... Relying on these natural materials, there is still a slight possibility. ”

"Professor, your argument is too difficult, too idealistic...... another expert questioned, "it can only be a dictatorship...... Only the dictator has gone mad will issue such an order. There is no such possibility for a democratic government, and the people have long been ousted from power. ”

Listening to these discussions, Zhang Yuan sighed: "In other words, in that case, there is a high probability that human beings will be stuck, and there is nothing to justify." Knowing only the term electricity, how can they try to study wires, magnets, electromagnetic induction? ”

"Continuing to deduce, in the universe, it is difficult to develop real technology on planets without oxygen? That's really ...... It's weird. ”

"I've thought of another way, biosmelting! The changes in life are limitless, and on Earth, there are bacteria that have a good accumulation effect on soluble metals at high temperatures. Maybe some planetary creatures can rely on themselves to smelt metals? ”

"It's not impossible, but it's low. You can't ask all the creatures on the oxygen-free planet to evolve the ability to biosmelt......"

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

This condition is indeed a bit harsh, there must be a small number of planets with a lot of oxygen, oxygen is produced by plant photosynthesis, and it cannot be born out of thin air. The reactive chemical nature of oxygen means that if it is not produced continuously, it will quickly react with other substances and be depleted.

Oxygen-free planets are the majority.

Because of this, the productivity of the Gliese civilization has always been in the Stone Age, and there is no way to separate the natural elements chemically, and there is no way to study electricity physically.

When it rains, it produces lightning, which is the only natural phenomenon they can observe related to electricity. Various physical models have come up with one after another, and some people have even given their lives to touch 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 are really difficult for outsiders to understand......

"I don't know, I don't know anything...... We know nothing about the world, as if a layer of darkness has clouded our eyes and obscured our path forward. We know that electricity exists and that it can exert magical powers. ”

"But all attempts came to nothing......"

The wise man, who studied from youth, to middle age, to old age, exhausted all his efforts and achieved nothing, wrote sadly in his diary: "Damn electricity, what the hell is ...... What the?! ”

At this time, it was already ...... from the departure of the enlightener civilization It's been 30,000 years.

The moment he saw this paragraph, it seemed that something hit Zhang Yuan's heartstrings, as a scientific research worker, why didn't he often sigh like this?

The universe is so unforgiving, stucking a civilization that only needs a small catalyst missing.

Just because there's no oxygen.

There is no mockery, compared to the Gliese civilization, human beings are just a little more lucky, at least they have developed their own technology, and they have penetrated the bits and pieces of truth of the universe.

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

"There is something missing, or a reason that we don't know...... Or something else......"

The evolution of history continues, not shifted by the will of any life......

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

Mathematics is thriving. Because mathematics does not need to be experimentally verified, it is not limited to productivity, as long as it is logical.

Year after year, 10,000 years after 10,000 years......

The technology tree of the Gliese civilization is starting to deviate badly, math takes the lead, and other disciplines are in shambles!

Ironically, the level of mathematics has even surpassed that of human beings! However, the tools used are still the most primitive tools such as stone and wood!
