Du Gang still suppressed his emotions and asked, "So, what are the standards of first-level civilization?"

Pang Ze said lightly: "There are two to meet the standards of first-level civilization!"

"First, science and technology naturally evolved to a first-level civilization standard, that is, it is able to reasonably use the parent star resources to realize travel, colonization, etc. in terms of energy technology, proficient in using quark fusion!"

Du Gang just knew about the quark fusion, and he discussed it with his physical education teacher during physical education class.

Not long ago, the Science Journal published an experiment on quark fusion.

In a nuclear fusion made of heavy water, the energy released by the fusion of a deuterium atom and a tritium atom is about 17 megelectron volts, while the quark fusion formed by the collision of two subatoms has 138 megelectron volts of energy!

This experiment proves that quark fusion is a more advanced fusion method than nuclear fusion, and its power is more than eight times that of nuclear fusion!

However, due to some technical obstacles, it cannot be applied to reality. According to inference, it will take at least one hundred to two hundred years of accumulation on Earth to truly master quark fusion!

It is obvious that the earth's civilizations do not master quark fusion now, which does not meet the standards of their first-level scientific and technological civilization!

Du Gang asked again: "What about another standard for advancing to a first-level civilization?"

Pang Ze smiled and said, "Flying Star!"

"As long as this civilization is born, the first meteorite-level powerhouse is born, it means that their civilization has reached the first-level civilization standard...even if this civilization has not developed technology!"

"Believe me, it is definitely more difficult to advance to level one civilization with Meteor Star level than to advance to level one civilization with technology!"

"However, for the same first-level civilization, it is exactly the opposite to the difficulty of advancing to a second-level civilization!"

Du Gang was very curious about the information about the universe at this moment, and wished that all the situations could be learned. He asked quickly: "What do you mean is that level one technology civilization is more difficult to advance to level two? Why?"

Pang Ze smiled and said, "To give the simplest example, for example, the carrier pigeons in your country are responsible for delivering messages, each price is ten yuan!"

"Then, now someone tells you that he will install the base station for you for free and sell it to you a contact number that costs only ten yuan? Tell me? Are you planning to use a carrier pigeon or a phone?"

"Of course I used the phone!"

This is a naturally developed technological blockade? The same product? Other people’s products are better than you and cheaper than you. At this time? It will be very difficult for you to develop your own products!

Du Gang thought about the situation on Earth about chip technology? Buying chips for domestic mobile phones? There are hundreds or hundreds of billions of yuan a year, but if you re-research on chips, the cost will be more than ten times the price of buying them!

Because you are researching, others are also researching? You may have been researching the fifth generation? Others have been in the fifteenth generation!

The market will make its own choices for the same price and different products!

This is just the technology of two different countries inside the earth, which has already opened up such a far technological gap.

If it is put into the universe, the technological gap is even more obvious. Is it a few hundred generations? A few thousand generations apart!

Maybe, if you have been studying here for tens of thousands of years? Maybe you may not be able to keep up with the technology included in other people's latest products!

But the problem is, research requires funds? Other people's funds? The consumer pays the bill? And your funds can only be borne by your civilization, unless you are willing to let your civilization always use the carrier pigeon!

Therefore, technical barriers are formed naturally!

In just a few dozen seconds, Du Gang understood why the first-level scientific and technological civilization was difficult to advance to the second-level scientific and technological civilization as Pang Ze mentioned.

Just like a computer assembly company, the money he earns from assembling agents is more than what he earns from R&D himself, so he will not spend money and time in R&D... But in fact, this is a vicious cycle, and the technology will grow bigger and bigger!

Why can you understand the technology that others have formed in millions or even tens of millions of years?

After thinking about these problems, he felt a little heavy, which means that in the field of science and technology, the earth's civilization is about to enter that vicious cycle.

However, he asked curiously: "Then, what is the symbol of the second-level technological civilization?"

Pang Ze smiled and said, "The annihilation of positive and anti-matter is a technology that is more powerful than quark fusion!"

"If quark fusion is still within your understanding, then the annihilation of positive and anti-matter is an unimaginable existence..."

"The energy that this technology can generate is about a hundred times more than your nuclear fusion? One thousand times more? Sorry, I actually don't understand this thing very much!"

He thought about it and said:

"Well, how do you say that spaceship in the sky is a three-star e-class spaceship of our association. It has space jumping technology and can span a distance of twenty light years... It is loaded with positive and anti-matter annihilation technology. Only the energy generated by this technology can achieve space jumping!"

"Of course, raw materials that can annihilate positive and anti-matter are very expensive. You don't know how expensive the civilizations that control this technology are..."

Du Gang has a simple understanding of the second-level civilization, which is very powerful!

"Is this kind of secondary civilization very rare?"

Pang Ze smiled and said, "The second-level civilization is not rare, but the second-level technological civilization is very rare!"

"I'll say that, the entire Waste Saturn Domain has even a third-level civilization, but there is no second-level technological civilization!"

Du Gang pointed to the spaceship floating in the sky in confusion and asked, "What are your spaceships?"

"I bought it next door!"

Pang Ze suddenly pressed a button on his watch, and suddenly, a bunch of pictures were cast out of thin air.

"I'll show you the real universe!"

Soon, a vortex-shaped galaxy appeared on the projection.

Du Gang blurted out, "Milky Way?!"

Pang Ze nodded and said, "Yes, this is the Milky Way!"

He asked back, "Do you know the position of the Milky Way in the universe?"

Du Gang shook his head. He discussed this with his physical education teacher that the earth has not yet discovered how big the universe is and where the center of the universe is.

Pang Ze smiled and said, "The center of the universe is there!"

As he said that, he stretched out his hand and pointed at Tianyu.

Du Gang's mouth twitched and ignored him.

Pang Ze smiled and continued, "Okay, I don't know where the center of the universe is. I didn't expect you to be fooled..."

"Back to the point, no matter where the center of the universe is, it does exist!"

"There are about two trillion galaxies like our Milky Way..."

Du Gang did not deny that there are 5 billion galaxies similar to the size of the Milky Way that have been discovered on the Earth. It is reasonable to find out more at the level of these advanced civilizations!

"Our Milky Way is far from the center of the universe. It can be said that it is in the suburbs, roughly at the location of the Fifth Ring Road. Of course, there may be hundreds of billions of similar galaxies between each ring..."

"Let's talk about the Milky Way, other places are not what we should know!"

He asked again: "Do you know how many stars there are in the Milky Way?"

"More than 1,25 billion?" Du Gang said tentatively, this is the number of stars detected by the Earth.

"more than!"

Pang Ze smiled and said, "The Milky Way has about one trillion stars, which means there are one trillion galaxies here..."

"The universe is too big, and the Milky Way is too big. Just talking about galaxies is too complicated. Therefore, we generally name some star fields with other meanings. Each star field contains a bunch of galaxies..."

"For example, in a distant place, there are powerful civilizations that ruled hundreds of thousands or millions of galaxies and formed a country that belongs to them alone. In this way, the star domain will be named after the country..."

"We are now in the position of the third cantilever of the Milky Way and the end of the ninth section, called the Waste Saturn Domain!"

"Waste Saturn Domain..."

Du Gang chewed it and asked back, "We are under the rule of a country called Wasteland?"

"no!"

Pang Ze looked at him regretfully and smiled: "The real situation is worse than this, I'll tell you later..."

"What I want to talk about now is the Purple Lan Star Domain!"

As he said that, he waved his hand and pulled the galaxy that was spinning in the projection closer.

Soon, a strange star field appeared, densely packed with stars shining in it.

"The Purple Lan Star Domain, also known as the Purple Lan Principality, has a ruling territory of 300 light-years in diameter and has more than a thousand galaxies. It is the closest star domain to us..."

"The Principality of Zilan is what I said. The only second-level scientific and technological civilization here is here. Their actual civilization level has reached level five, but the scientific and technological civilization is only at level two. What can you understand from here?"

Du Gang blurted out, "They are also blocked by technology?!"

Pang Ze nodded, "That's right, the Principality of Zilan has existed for millions of years. It took such a long time to develop to achieve a second-level scientific and technological civilization. It is conceivable that in the field of science and technology, the dominance of high-level civilization over low-level civilizations..."

"Level 5 civilization..."

Du Gang asked quickly: "What you mean by the level 5 civilization is force?"

"Yes, the meteoric star level can be called a first-level civilization. If the meteoric star level is a second-level civilization, if the comet is a third-level civilization, the strongest one in our wasteland is a third-level civilization..."

"However, generally we are not called civilization, but are commensurate with forces, such as first-level forces, second-level forces, and third-level forces!"

"I understand!"

Du Gang nodded and asked, "Then what you have been saying, how big is our wasteland field? What do you mean?"

Pang Ze quickly adjusted the star domain map and released galaxies including the solar system.

"See it. Here, the spherical star field with a diameter of more than 100 light-years is the Waste Saturn field..."

In the projection, all galaxies are not arranged in planes, but are three-dimensional, with uneven layers such as up, down, down, left, and right.

"We call the surface of the Milky Way moving as a silver plate, or a silver plate. On this silver plate, the upper silver plate is the upper silver plate, and the lower silver plate is the lower silver plate..."
