I have a little black hole

As for the harvest of various metals, Lei Tiantang is too lazy to count the specific quality of them. Anyway, now he doesn’t know how long it will take to harvest this harvest. He simply estimates 6 9 gold. There are probably more than 300,000 tons at a time. How much of this gold can he use on the earth?It's not as useful as iron. At least iron's usefulness can be used a lot when he builds his own underground laboratory.

With such a large amount of harvest, Lei Tiantang finally has the passion for work again, the universe is so big, I want to go and see!And if you want to go to the waves in the universe, then at least you have to have a spaceship, and you have to be a super high-speed super-lightship!Otherwise, if the conventional spacecraft does not have a super-light speed engine, then it can only travel at a speed lower than the speed of light, even if you fly faster.

In the vast expanse of space, there are countless stars, of which the closest star to the sun is called Proxima Centauri. It is located in Centauri. Scientific name: Alpha Centauri C, only 4.22 light-years from the sun, equivalent to 399.3233 billion kilometers. .If you use the fastest spaceship now to travel to Proximity Star, it will take 170,000 years to go back and forth. It is conceivable that the universe is so big, even if Proximity is far from the horizon.

In this comparison, everyone should know the difficulty of waves in the universe?Even if we drive an ordinary spaceship to 0.99 times the speed of light, it will take more than 4 years to get to the neighboring star. That is the nearest galaxy to the earth. How long will the spacecraft reach this speed?

Lei Tiantang is still very thoughtful about this point. He has no doubt that he can go to the waves in the universe, because he can handle the most important materials for the spacecraft. There is no problem with any quality materials, of course. A spaceship that can fly in the universe is a huge system engineering, but it is not necessary to have materials.

Therefore, Lei Tiantang set a small goal for his plan first, to build a spaceship that can sail in the solar system. With the current technology, there is no problem if it develops and develops. Now it is restricted that humans cannot use the solar system spacecraft. The main reason for the creation is the material problem. Without good material, the thrust of the rocket cannot go up. It is impossible to send a large spaceship into space. Even if it is not guaranteed in space safety, there are too many dangers in space. All kinds of radiation and space dust can threaten the safety of the spacecraft.

If you want to build a spacecraft that can take off directly from the earth, there are more things to do, because humans have never done anything in this regard, so everything must be started from the beginning, but Lei Tiantang is still very Confidently, he can solve the most critical material problem, and the rest is the design.

Of course, design and construction is also a big project. Each system of the spacecraft has only limited experience to learn from, and almost all have to start from scratch. Like the communication in the universe, it is definitely the choice of quantum communication, and quantum communication is still at the forefront of science. Technology, and China is at the leading level in this field, but there is still a long way to go before mature applications can be used in spacecraft.

Another example is the spacecraft's life support system. Although there is an example of the International Space Station, the International Space Station is supplied on a regular basis. If Lei Tiantang needs the spacecraft to travel in the solar system for a long time, the supply will be a big problem. Can't you still launch supply ships often?Therefore, the sustainable life support system on the spacecraft is very important, and green plants can also relieve the anxiety of astronauts in confined spaces for a long time.

There is also the engine of the spaceship. Of course, a large-quality spacecraft needs a powerful engine to take off from the earth. There is almost no precedent for such an engine. So it must be designed and manufactured from scratch. This will be another big project.

There are also such things as control systems, escape systems, etc., which are almost all designed from scratch, but Lei Tiantang has not been frightened by these problems. His life has already been hung up, and now he can have a goal for him to struggle But it's a good thing, otherwise do you think about how to make money every day?He is not going to lose money now, not to mention the value of the precious metals like gold that he has, just to say that he is now focusing on the development of new materials companies, and when new laboratory equipment arrives, he will open up to help develop some new materials. , How much does it cost?

Of course, there is nothing wrong with having money. To build a spaceship, you must spend astronomical money, but it is not enough to have money. The key is that sometimes you have no money. It is like Lei Tiantang plans to make a spaceship. Without the participation of the country, Lei Tiantang alone and his company can never do it.

Lei Tiantang had thought about this when he thought of this small goal. Many things cannot be done without the participation of the country. The simplest point is that the top talents are almost the treasures of the country and want to design a spaceship. You must ask these babies to participate, otherwise if you recruit some talents to train yourself and come to participate in the design, then this spaceship can't be built without knowing the Year of the Monkey!

The point is that you must be able to work in such a big project like a superpower like Huaxia, because he has the foundation of this industry and there is no shortage of talents. If you want to build a spaceship in a country like India, Then you have a dream, they can't even make their own guns!Therefore, Lei Tiantang must obtain national support.

And it is definitely impossible for the country to agree to such a plan in advance. It is estimated that the country will not participate until the middle and late stages, because if it is an individual, it will go to the country and say that I want to build a spaceship. The country will take care of you. Money doesn't work, you have to prove that you can do this, and then go to the country for help, so that is the way to do things, otherwise the slogans of Tian Xiang are useless.

However, he still has to keep in touch with the country in the early stage, and Lei Tiantang has also chosen the target in his early contact. His company is going to carry out research on new materials. When the laboratory equipment returns, he intends to develop it first. The new material is stealth paint, which is the stealth paint used on high-end armaments such as stealth fighters. The current stealth paint is basically repainted all day at most several times, like the US F22.

There are several F22s in his storage space. There are ready-made invisible paints for his reference. After he solves the situation that invisible paints are not durable, his company will also become a national key military cooperation unit. When he develops new materials in the future, he will gradually cooperate with the country, and when he has prepared the spaceship's preparatory work, it will be very convenient to go to the country for cooperation.
