Fighting The Galaxy

As a planet based on commerce, the most prosperous business star is not the surface of the planet, but synchronous orbit.

Synchronous orbit is a special position on the planet ’s equator, where the rotation angular velocity is consistent with the planet, so that it can be fixed relative to the ground. When a civilization begins to enter the interstellar age, the space elevator must have A means of this kind, such a space elevator, is to lead to synchronous orbit.

The same is true on Shangxing. It has developed to the extreme. There are tens of thousands of space elevators leading to the synchronous orbits outside. The synchronous orbits have all been connected to form a complete circle. That is huge The dock structure on the synchronous orbit of the metal frame structure is showing a huge outline under the stars. This look is like a halo outside Saturn. If you can see those space elevators, it is like a circle. The huge wheels and spokes are average and look interesting.

Now, Qin Tian is like this, looking at the huge space berth gradually approaching outside. Suddenly, his eyes pass through these devices and project onto the planet.

The planet here is very strange, with a crystal clear feeling, like a crystal ball, yes, and the crystal ball is so similar, let Qin Tian involuntarily want to touch the general.

This planet looks so strange.

"This is a Mercury." Princess Jing Xi said.

Princess Jingxi has been to many places, and when she is an adult, she can travel in the entire empire, and when she is looking for Qin Tian, ​​she does not know how many planets have been searched in the starry sky of the entire empire. Various planet surfaces.

Some planets are solid. These planets are the most suitable for the growth and reproduction of civilization. Of course, there must be appropriate light, air and water, etc. Some planets are gaseous planets. These planets are generally few people involved. In general, gaseous planets are composed of light gas, and in the liquid ocean below, there is inexhaustible fuel.

There is another category, that is, the surface of the entire planet is covered with a layer of liquid. This is a liquid planet.

This also requires suitable conditions. Different liquids have different freezing temperatures. If the distance to the star is not appropriate, or the liquid is too hot, it will volatilize into gas, or if it is too cold, the liquid will freeze into ice sheets.

As it is now, the surface is liquid, and it is still water, which is a rare type in the Milky Way. The entire planet ’s surface is completely covered by water, forming this unique Mercury. Looking at it from space, there is a A different kind of beauty.

Of course, there is a solid core under the surface of the liquid. If the entire planet is full of liquid, then there must be not enough attraction to keep its state unchanged, and it has fallen apart in rotation.

Moreover, these space elevators must be deep under the liquid and connected to the land. It is impossible to set up on a ship floating on the surface of the liquid?

"Yes, it's Mercury." The old man in the back said: "In this outer pier, big ships are moored, and big deals are done. Some small ships can enter the liquid ocean below, where It is divided into many regions, different businesses, and transactions in different regions. The following are all small businesses, including wholesale and retail. "

auzw.com is talking about small business, which is also relative to the upper level. In fact, the above small business is definitely not small, it is all heavyweight, tens of thousands of tons of old man talk The raw materials of Dongpo's elbows were chatted below.

The above is booming, big business, small vendors on the surface of Mercury, small business, do their own, without affecting each other.

At this time, Mercury's surface still has certain advantages.

Because transportation on the water is easier than on land!

In this era, large transport ships rarely land on the surface of the planet. If they land, how many wheels do they need to be able to withstand the weight of the transport ship? Once you land, you do n’t know how many tires you want to blow up. Besides, they do n’t have any tires at all.

If it is an ice sheet, they can directly land on the strengthened abdomen. If it is ordinary ground, it is almost difficult to land, unless it is a small spaceship such as its own big mouth.

But the surface of the water is different. If it is on the water, the giant transport ship can also land on the water when needed. As long as the transport ship has a streamlined shape design, it must be sealed and use space. The spacecraft made of alloy can definitely float on the water, so that it is possible to land on the water. At the same time, when trading on the water, negotiating the price, moving the goods and buying it is like a huge As in the vegetable market, the semi-trailer transports the goods, and then, with a light truck or even a vegetable seller riding an electric three-wheeler, they can come over and buy it, and they will soon be able to transport all the goods away. This kind of thing, It is inconvenient in space, because the terminal is limited. People who do big business, just trade on the terminal. Their wholesale to retail trade on the surface of the planet.

It can be a commercial center. In addition to convenient transportation, the entire surface of the planet is water, which is also an advantageous aspect.

Mr. Duan explained this in a few words. Hearing Qin Tian was an eye-opener. Even Pete admired him. Pete once wondered why Shangxing had to be established on Mercury. So this is for convenience.

"Strange, what about its atmosphere?" At this time, with the gradual approach, Mercury is becoming more and more clear, especially when looking at its morning and evening faces, it is even more peculiar. If there is an atmosphere, due to various physical principles, such as refraction, Scattering and so on, its edges should be blurry, so clear now, clearly there is no atmosphere!

Where is its atmosphere?

If a planet needs to be able to carry out a large number of activities, it must at least be able to allow people to breathe normally, not to trade in spacesuits, right? Humans need to be able to live normally, but now, looking at each other, it is clear that there is no atmosphere!

"It has an atmosphere, but its atmosphere is very thin, only about two hundred meters." As a person who has been here, the old man can now at least serve as a guide and a tour guide to introduce to you.

For everyone, this planet is full of mystery.
