I have a shelter in the last days

In fact, it is reasonable to say that it is very cautious to let other alien civilizations enter human spaceships, because a spaceship of a civilization contains the technology of this civilization, from the manufacturing materials of the spaceship, power system, communication equipment, control system, and even The life support system can analyze a large number of related technological contexts and characteristics of civilized life forms.It can be said that the scientific and technological strength of a civilization can be roughly deduced from the technology used by the spacecraft, and the technological strength of a civilization is often equal to its combat effectiveness.

The reason why Zhuo Fan dared to agree to Jiujiu's request, and he was not afraid of Jiujiu's contact and use of human technological equipment, was actually because the technological strength of the two parties was too different.This kind of difference in scientific and technological strength of countless generations makes all human technological products black boxes for insects, that is to say, they can only see the output results of human technological equipment, and it is completely impossible to figure out its working principle.Zhuo Fan can confidently ascertain that the smartest bugman on the planet cannot obtain any valuable secrets of human technology from the Iron Spike.

"Of course it's no problem. I'm going to explain the situation to my father!" Jiujiu stood up excitedly and ran towards the conference hall. Halfway through the run, he stopped again and asked a little embarrassedly: "Then I can bring Is my teacher here? And his friends, they are all scholars, and they are full of curiosity about you... The most important thing is that my teacher has been studying the laws of motion related to the stars."

"Sorry, you can only board the ship by yourself this time. There will definitely be the same opportunities when our fleet arrives. And there will be a lot of opportunities." Zhuo Fan smiled.

At present, there are only 6 people in the entire mace brigade, and he doesn't want to take even the slightest risk to get more buggers on the Iron Spike. Although he doesn't think these buggers have the courage to be against them, but There is absolutely nothing wrong with taking precautions before they happen. Many times, when some people do bad things, they do not start out with the mentality of doing bad things, but suddenly find that there is a particularly good opportunity to do bad things. Under the mentality of a gambler Just went astray, Zhuo Fan didn't want to create a condition to seduce the Zerg people to go astray.

"Then my teacher must be so envious that I can go to the starry sky earlier than him, thank you, Mr. Zhuo Fan." Jiujiu bowed slightly, then folded the tentacles on the top of his head and made a solemn etiquette and labored. The syllable of Zhuo Fan.

What should it look like in the starry sky?

Jiujiu couldn't imagine that even though he had seen brief cosmic science education films about human beings (at the insistence of human beings, the Zergs finally officially changed the name of human beings from the people of the starry sky to the human beings of the earth, or human beings for short), but he excluded those science education films. Still can't rely on my own wisdom to imagine what kind of scene it should be above the clouds and in the starry sky outside the screen.He rejected some other similar audio-visual materials that Zhuo Fan prepared for him, and insisted on using his own eyes to see the scenery that no one in his race had ever seen before.

At this moment, Jiujiu was bound to the seat like a bunch of seat belts, like a fixed insect specimen.The seat insects developed by humans based on their own ergonomics is actually uncomfortable to ride on, because the body structure of the insects is not suitable for sitting on a chair with an angle of about 90 degrees.Although Jiujiu has now made some modifications to the seat according to the physical characteristics of the buggers, so that it can lie on it in a relatively more comfortable posture, but it is obvious that Jiujiu has never had the experience of bundling a seat belt. It feels very awkward and even a little bit ashamed.

Su Xiaoxiao looked at the awkward posture of Jiujiu tied to the chair with six legs facing the sky (some insects look like cockroaches, and some look like praying mantises, with six limbs in total, of which the rear limbs are feet for walking, and the front two limbs are hands. ) couldn't hold back the laughter until his face turned red.

Jiujiu was a little embarrassed, but more nervous. He couldn't help asking: "Why do you have to fix yourself on the chair while flying? Is it because of danger? If there is danger, do I need to do something?"

Evans laughed loudly and said: "When we humans first left the planet and entered the starry sky a long time ago, it was dangerous because of immature technology. But after hundreds of years of technological progress, it is now very mature to enter space from the planet. There is no danger. For us, entering space is as common as riding a screeching bug. But because the operation manual requires that all spaceships must be strapped when entering and exiting the atmosphere or approaching strange objects in the universe. Seat belts, we do this. This is because various unexpected situations may occur in the universe at any time, and these situations will cause the spacecraft to bump or be hit. If you don’t fix your body, it is still easy to get injured.”

"Because Jiujiu is your first time in space, you may feel some physical discomfort at the beginning, but it's not a big problem. Although the life support system on the Iron Spike is based on the needs of human beings to create an ecological environment. But We have done many experiments before, you can completely survive in our ecological environment, you don’t need to be so nervous, just get used to it when the time comes.” Guan Xiaoyue, as a medical staff, reminded Jiujiu very thoughtfully.

Jiujiu nodded in confusion. To be honest, he didn't quite understand what this female human named Guan Xiaoyue said.He didn't know what the life support system or the ecological environment meant, but he roughly guessed the general meaning of what this human being said, that is, he should be safe on this spaceship, so he didn't need to worry.

As the roar of the engine became louder, the Iron Spike slowly began to rise from the ground, and then began to accelerate into the air.In fact, it is not necessary to obtain a very high initial velocity to get rid of the gravity of the planet and enter the space. The so-called second cosmic velocity actually refers to the minimum initial velocity required by an object on a planet to escape the gravity of the planet without external power. speed.In fact, as long as the energy source is continuously provided with enough power, the power greater than its own weight can help the spacecraft get rid of gravity and enter space.

In the atmosphere, the Iron Spike will adopt a working mode similar to that of a jet engine, using air as a working medium to accelerate and bring propulsion.When the flight reaches a certain altitude, as the atmosphere begins to become thinner, it will change to pulse propulsion.The so-called pulse propulsion is actually similar to a nuclear rocket. A large amount of nuclear fuel is fused in a fusion engine at one time to generate huge energy similar to a small nuclear bomb, and then the energy is ejected and converted into kinetic energy of the spacecraft.

Due to the problem of energy density, most of the weight of aircraft such as chemical energy rockets is used to carry fuel. This will cause the carrying ratio of this aircraft to be very high on a planet with a large enough radius and a large enough mass, that is, a planet with a high enough gravitational force. So small that it is very uneconomical in engineering and economics.However, the Iron Nail, which uses controllable nuclear fusion as its power source, does not have this problem. The energy generated by the fusion reactor with a power of up to [-] million kilowatts is enough to successfully send this spacecraft with only a few thousand tons into space.
