Chapter 245 (1/2)

The Gliese have indeed known the existence of electricity. With some small Enlightenment Given by the ”enlightener civilization”, they have the possibility to jump directly from the stone age to the electric age.

Unfortunately, this step is very, very difficult.

For a whole hundred thousand years, countless capable people and wise men have launched attacks again and again, but no one has taken this crucial step.

Just because there is no oxygen

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

”No technology was born? It took them so long to produce real technology? ”

”Are the real technologies given to them by the second batch of aliens?”

The professor on the stage smiled meaningfully, as if he expected that all of you here would have such a response: ”ladies and gentlemen, I have a question. If human beings are faced with this dilemma and have a certain amount of scientific thinking without oxygen, can they jump directly from the stone age to the electric age.”

The crowd gradually became silent and began to think seriously.

”... it's incredibly difficult.” Captain Zhao, sitting in front, shook his head gently.

The absence of oxygen means that there is no natural combustion phenomenon, 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 to make copper and iron is carbon reduction method. At high temperature, carbon is used as reducing agent to conduct redox reaction on metal minerals to smelt metal elements.

But this method requires a very high temperature. For Gliese without combustion, it is undoubtedly 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 that little possibility.

But when Gliese encounter volcanoes, it's too late to escape. How can they risk their lives to make iron? They don't even know the so-called chemical reaction equation!

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

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

The development of science is gradual. Even if they have good scientific thinking, they also need experiments to support the proposed views.

Science is a methodology. After putting forward a point of view, 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, this view will undoubtedly be abandoned.

But the question is, how?

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

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 the enlightener civilization, the Gliese have known that the magical natural phenomenon of ”electricity” exists and can be transformed into great power. But how can we study electricity without iron, copper or even conductors?

The scholar sitting in front of Zhang Yuan turned his head and said, ”in this case, there are two ways I can think of. First, I clearly know what electricity is. Just like us, we have mastered this knowledge. If we suddenly run to the stone age, we can jump directly into technology, bronze and black iron. ”

Zhang Yuan shook his head: ”no, I don't know why. The enlightener civilization only told them the existence of electricity, but didn't tell them the essence of electricity, let alone phenomena such as electromagnetic induction, so they can only grope blindly in the fog.”

”Then, the second plan, with the strength of the whole country, gives priority to power research and relies on a large number of talents to attack these bottlenecks. The oxygen content of their planet is low. Iron, copper and magnets also exist in nature... It is still a little possible to rely on these natural materials. ”

”Professor, your statement is too difficult and idealistic...” another expert questioned: ”it can only be an authoritarian government... Such orders will be issued only when the dictator is crazy. There is no such possibility of a democratic government. The people have long been ousted. ”
