Chapter 392

The picture came out.

This is a light blue planet, green vegetation, huge ocean, snow capped mountains When you see these pictures, the next generations don't feel much about them. However, these scenes have made great waves in the hearts of the first generation of new civilized citizens. It's a replica of the earth!

It is not only these natural phenomena, but also the traces of civilization.

City, real city!

One by one, just like farmland, is distributed in blocks

there is also a large floating device as big as a large group of ants, which travels to and from various areas. It should be the so-called means of transportation - empty boat!

An old astronomy expert said with a slightly excited look: "it seems that real modern technology has been developed, but limited to the high gravity of the planet, this civilization has not explored the universe."

“…… Instead, it has developed a transportation network with empty boats as its core. "

These scientists are writing astronomical reports while they are discussing enthusiastically.

"No satellite?"

"Yes, not even space junk. There should be no satellites. "

"The potential of a civilization has been strangled by the planet itself. It's really an unlucky civilization..."

“…… I don't know if the enlightenment civilization has left any traces on this planet? With the wisdom of the enlightener, we should have known for a long time that this civilization will encounter such a situation. "

Since our strength is far stronger than the civilization of the other side, we have nothing to worry about.

Dealing with a civilization with modern technology is a very interesting and desirable thing. However, because of gravity, it is impossible for human beings to land on the ground for field investigation, which is the limitation of human beings. Otherwise, many people still want to travel in person.

The astronomer wrote in his report that " The surface of the star is blue, and most of it is the ocean. The ocean area accounts for 82% of the whole planet, and only 18% of the area is land and glaciers. "

"The huge ocean leads to abundant precipitation and vegetation on the surface of the planet. The average temperature is about 30 degrees centigrade, and there are huge glaciers in the two levels... "

The larger the ocean, the more abundant the precipitation. On the contrary, if the ocean area only accounts for 60% or even 50% of the planet, the probability of large deserts on land will be doubled.

"We have observed the existence of indigenous civilization on the planet tepp. According to satellite observations, the individuals of this civilization are generally not tall. They are about 1.7 meters long and muscular. Their walking style is similar to that of orangutans, that is, two forelimbs can assist walking It may be due to the fight against high gravity, and its specific body structure needs to be investigated. "

“…… Wearing clothes may be culturally similar to human beings. "

There are civilizations that don't wear clothes. For example, the badit civilization, imprisoned in the virtual world, has no gender and no sense of shame between men and women.

The ritual of meeting each other is to exchange germ cells.

Badit people are very strong and don't need to wear clothes to keep their body temperature.

As for the space suits they were wearing That's another thing. It's not normal clothes.

The Laili people, who once visited the religious civilization, do not wear clothes because they are still in the primitive times. They are too poor to wear clothes. In addition to the warm climate, they do not need clothes to protect themselves from the wind and rain.

The aristocrats in the upper class of Riley civilization had some simple decorative habits, especially the metal ornaments and some fabrics traded by human beings, which made them form the habit of dressing to a certain extent.

Joking, no clothes, when what noble, is simply a symbol of decline and no taste!

At present, the TAPP civilization seems to be dressed, which may be similar to human beings in terms of culture.

“…… Due to the different environment of the planet, the planet has developed a science and technology system with empty boats and ships as the main means of transportation. Different from the earth's traditional land vehicles, due to the high performance of materials, land vehicles are not widely used. "

In other words, this civilized land transportation tool is not without, but it is not used on a large scale.

This kind of thing can be known almost without thinking about it. Under three times of gravity, the weight of 1000 Jin becomes 3000 Jin. Even if an ordinary car can be started and does not carry any goods, it will be directly overweight.

If we use the cheap rubber tire which is very common in human beings, the probability of tire burst will be greatly increased. Bridges and the like are also prone to collapse. The material properties of the so-called reinforced concrete will not be enhanced because of the high gravity of the planet.

Especially for single column pier bridge, it is easier to roll over due to the imbalance of pressure distribution.

However, the train can only carry less than one-third of the goods of the earth's train. Otherwise, the wear of tires and rails will increase greatlyIf it's loaded too much, maybe the tracks will be flattened!

The maglev train is also the same. The requirements for materials are greatly improved. This civilization has not developed into a third level civilization like human beings. They do not have super magnetic-a materials. Even new humans can't afford to use supermagnetic-a on maglev trains.

On the other hand, when the air pressure increases, the buoyancy of the air will increase, which is beyond doubt. The proportion of pressure increase on this planet is higher than gravity, so empty boats become a very suitable means of transportation.

The main transportation system with small empty boats as the core appears on this planet. Short distance traffic is done by empty boats From a certain point of view, this civilization can be called the empty boat civilization.

As for the long-distance traffic, of course, it's large ships. The buoyancy of the water is the same as the weight of the discharged water, and the buoyancy will increase as the gravity of the planet changes. If a piece of wood is lost in the ocean of the earth, it will float, and if it is lost in the ocean of TEP, it will also float.

So, ocean liner is still no problem, and the performance requirements of materials are not high, so it has naturally become the first choice for long-distance trade.

Soon, this detailed astronomical report was delivered to the captain's room.

Zhang Yuan had a lively discussion with his colleagues for a long time. It is generally believed that the scientific and technological strength of this civilization lies between the 20th century and the 21st century

It seems that the technology tree is a little bit crooked, but it remains to be seen how.

Li Zhendong frowned and said: "big probability Controllable nuclear fusion technology has not yet been developed, there are no satellites, and it is hard to say whether there is Internet, but radio technology should be developed. Radio communications are also widely used. "

"Our satellite has captured some exposed radio waves People in the research institute are analyzing these electromagnetic waves. They should be the universal digital code. They don't encrypt them very much. If they can directly crack the language, they will have less trouble. There are also some very traditional telegrams

Although he is retired, he is also an old expert in password decoding. Many times, young people are not necessarily comparable to experienced old experts.
