Chapter 400

The picture came out.

This is a light blue planet, green vegetation, huge oceans, snow capped mountains... When you see these photos, the generations behind you don't have much feeling, but the scenes have created huge waves in the hearts of the first generation of new civilized citizens. It's a replica of the earth!

Not only these natural phenomena, human beings have easily observed the traces of civilization.

City, real city!

One residence, just like farmland, is distributed in blocks

There is also a large group of large devices as big as ants floating in the air, which travel to and from various regions. It should be the so-called means of transportation - empty boats!

An old astronomy expert looked a little excited and said, "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."

"... on the contrary, a transportation network with empty boats as the core has been developed."

These scientists wrote astronomical reports while 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 wonder if the enlightener 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 own strength is far stronger than each other's civilization, we have nothing to worry about.

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

The astronomer wrote in the report: "... The surface of TEP is blue, and most of it is 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 on the planet's surface and vigorous vegetation growth. The average temperature is about 30 degrees Celsius, and there are huge glaciers at the two levels... "

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

"We have observed the existence of TEP's native civilization. According to satellite observations, the individuals of this civilization are generally not tall, about 1.7 meters long, have strong muscles, and the way of walking is similar to that of orangutans, that is, two forelimbs can assist in walking... It may be to combat high gravity, and its specific body structure needs to be investigated. "

"... wearing clothes may be culturally similar to humans."

Some civilizations 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 etiquette of meeting each other is to exchange germ cells.

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

As for the spacesuits they wear... That's another matter. They're not normal clothes.

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

The nobles in the upper class of Riley civilization had some simple decorative habits, especially after human beings traded metal ornaments and some fabrics to them, they developed a certain degree of clothing habits.

I'm kidding. Being an aristocrat without clothes is a symbol of decline and no taste!

The current TEP civilization seems to be dressed. It may be similar to human beings from the cultural level.

"... due to different planetary environments, the planet has developed a scientific and technological system with air boats and ships as the main means of transportation. Different from the earth's traditional land vehicles, land vehicles are not widely used because of their high performance of materials. "

In other words, this civilized land vehicle is not absent, but it has not been used on a large scale.

This kind of thing can be known almost without thinking. Under three times the gravity environment, the weight of 1000 kg becomes 3000 kg. Even if ordinary cars can start and do not carry any goods, they are directly overweight.

If cheap rubber tires are widely used in human beings, the probability of tire burst will increase significantly. Bridges and the like are also easy to collapse. The material properties of the so-called reinforced cement will not be enhanced due to the high gravity of the planet.

In particular, single pier bridges are more prone to rollover due to the imbalance of pressure distribution.

The train can barely start, but it can only carry less than one-third of the goods of the earth train. Otherwise, the wear of tires and tracks will increase significantly

If you load too much, maybe the rails will be flattened!

Maglev train is the same. The requirements for materials are greatly improved. Unlike human beings, this civilization has developed to level III civilization. They do not have super magnetic-a materials. Even new humans can't afford to use supermagnetism-a on maglev trains.

On the other hand, there is no doubt that when the air pressure increases, the buoyancy of the air will increase. The proportion of the increase of the planet's air pressure is greater than that of gravity, so the empty boat has become a very suitable means of transportation.

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

As for long-distance transportation, of course, it is a huge ship. The buoyancy of water is the same as the weight of discharged water, and the buoyancy will increase as the planet's gravity changes. If a piece of wood is thrown into the ocean of the earth, it will float. If it is thrown into the ocean of TEP, it will also float.

Therefore, the ocean going giant ship is still no problem, and the performance requirements for materials are not high. Naturally, it has become the first choice for long-distance trade.

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

Zhang Yuan happily discussed with his companions for a long time. It is generally believed that the scientific and technological strength of this civilization is between the 20th century and the 21st century

The technology tree looks a little crooked. It remains to be seen how it is.

Li Zhendong frowned and said, "high probability... Controllable nuclear fusion technology has not been developed. It is hard to say whether there is any satellite or Internet, but radio technology should be developed. Radio communication is also widely used. "

"Our satellite has captured some exposed radio waves... People in the research institute are analyzing these electromagnetic waves. They should be a universal digital password without much encryption. If they can directly crack the language, it will save a lot of trouble. Others are very traditional telegrams. "

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