Fighting The Galaxy

If the planet has an atmosphere, it is very beneficial to the planet. The atmosphere can wrap the planet and isolate it from the outside world. Once a meteorite comes down, most of it will be destroyed by friction and heat with the atmosphere and become a beautiful meteor. In the atmosphere, the planet will become bumpy, and large and small craters will appear.

At the same time, the atmosphere can also provide a suitable ecosphere. Life needs to be breathed. Plants and animals work together to finally make the various gases in the atmosphere moderate in content and facilitate their breathing.

At the same time, the atmosphere can also keep warm. The star's light shines on the planet. If there is no atmosphere, the surface of the planet directly contacts the universe. When the light is shining, it will be very warm. When it turns to the back, then It immediately became absolute zero.

With the atmosphere, the outer layer is a vacuum, absolutely zero degrees, and gradually warms toward the inside. When it reaches the ground, there is an area with a small temperature difference.

However, not all planets can have an atmosphere, which began to appear in the early stages of the evolution of the entire galaxy. During the evolution of the galaxy, it gradually merged from a nebula into a ball, and the sphere became larger and larger The gravitational force is getting stronger and stronger, and the lightest gas can also be attracted to the surface of the planet. Therefore, only a large enough planet can attract gas.

This planet, depending on the size of the individual, does not seem to be particularly attractive, so a thin atmosphere is also possible.

If it is meager, then the atmosphere is destined to not be particularly thick. The thin atmosphere is just like the mountain climbers pedaling the high peaks. Oxygen is not enough, that is to say, it must be impossible to breathe on it?

Seemingly knowing what Qin Tian was thinking, Mr. Duan continued to explain: "In order to allow humans to move freely above and allow various transactions to proceed normally, there are countless gas-making equipment on Shangxing."

Gas manufacturing equipment? The old man hadn't responded yet, and Pete had already said: "I guess it's electrolyzed water."

There are endless liquid oceans below. In this case, electrolyzed water is the most convenient source of oxygen. Long ago, when nuclear-powered submarines became popular, because nuclear power has sufficient power supply, it can be directly Electricity is used to make oxygen, which is electrolyzed water.

Water is composed of hydrogen and oxygen, and electrolysis opens the chemical bond between them, which is divided into hydrogen and oxygen. It takes a lot of energy to open this chemical bond.

This is also in a very ancient time, hydrogen energy cars are said to be new energy, the cleanest energy, but in fact it is a reason to fool people, hydrogen is indeed the cleanest, through fuel cells, only produced It ’s just water, and it ’s essentially an electric car with zero emissions. However, it takes a lot of energy to produce hydrogen. From the perspective of production, it ’s definitely better to directly extract the oil and use it. The energy comes from the sun.

It only talks about the clean energy of hydrogen, and it does not mention how to produce hydrogen and how to store hydrogen. That is ulterior motives. What ’s more, under the banner of water as a fuel, it ’s deceptive to say what water is used to produce hydrogen. Is it better to use a lot of electricity in the process of taking it to directly drive the car?

It ’s different now, because now nuclear fusion is mature, nuclear fusion is really the cleanest fuel. Nuclear fusion uses energy from atoms, and no pollution will occur. At the same time, fusion requires special Conditionally, once an out-of-control situation occurs, the fusion will stop directly, and there will never be an accident like a fission reactor.

In this way, in the liquid ocean, some nuclear fusion devices are used to generate electricity, and electricity is used to electrolyze water. The oxygen in the water is released into the air to maintain the density of the air. Of course, the generated hydrogen cannot be wasted, stored, pressurized Cooling and liquefaction is the fuel that the spacecraft needs.

auzw.com The spacecraft with antimatter engines is very few, most of them are only affordable for starships. Ordinary spacecraft use liquid hydrogen as fuel. In this way, Mercury also You can refuel the spaceship.

The thickness of the atmosphere is very small, only 200 meters, then there will be a lot of interesting conditions.

For example, in the outer layer, it's still a vacuum. Absolutely zero degrees. In the inner layer, it is already a normal water temperature range, which means that the temperature span is quite large in the interval of 200 meters.

Although the thickness of the atmosphere is 200 meters, it is best to stay at the bottom, about 20 meters, or even 10 meters, where the temperature and air pressure can maintain a similar level, and then go up , I am afraid it will be very uncomfortable.

If you jump on it, the body below can still move, your head has been frozen, or you can't breathe the air and hold back, it is possible.

Of course, we have tried our best to maintain the atmosphere of 200 meters, and this is not without any harm, there are benefits.

For example, it is convenient for spaceships to fly, and some cargo ships are not smooth in shape. They may not be able to enter the ordinary atmosphere, but the atmosphere here is very thin, so it can continue to fly around the planet, Decrease the height and speed, and when it is appropriate, then drill into the atmosphere and land quickly, which will reduce the impact in the atmosphere.

At the same time, the atmosphere is very thin, when the spacecraft takes off, it will quickly enter the vacuum, without air resistance, the acceleration will be faster.

In short, there are pros and cons.

"Please follow us, go around the planet five times, slow down to 100 meters per second, and then enter the atmosphere." A sound came from the headset.

The entire dock is empty, as if it has been abandoned in half, and their chamber of commerce has also entered the planet below from the most prosperous port circle on the synchronous orbit.

Now, instead of staying on the synchro track, they started to descend.

Now, I can finally see more clearly. I can see that on the planet, there are large areas of dark spots on the surface of the crystal-clear liquid ocean. Obviously, what is floating on the surface there can be easily imagined. The transport ship should float there.

If it were all, then it was simply a colonial cargo ship strike, which would cause great problems for the colonial transportation.
