$1,651 It's Not that Easy

The Americans definitely have more than one laboratory in Oak Ridge, but the aliens didn't attack other places, but this place. What exactly is their plan?

Thinking of this, Ye Han felt bad: "Chief, the aliens want to build nuclear weapons, they definitely want to build nuclear weapons!"

Wu Han's performance was calmer than Ye Han imagined: "They have wanted to build nuclear weapons for a long time, so why are they making such a fuss?"

This sentence was like a heavy pause, interrupting Ye Han's intense emotions, so that Ye Han didn't know what to say.

Seeing Ye Han's doubts, Wu Han showed a playful smile: "Is it necessary to be so excited? What? Can't figure it out?"

Ye Han said hesitantly: "It's not that I can't figure it out, I just feel that something is wrong."

Wu Han smiled: "Do you think aliens don't know how to build nuclear weapons?"

"Do you know?" Ye Han was a little stupid. "

"Of course I know." Wu Han's words shocked Ye Han's head and made him speechless.

"Is it strange? "Wu Han smiled a bit evilly, "Don't you think about it? The principle of nuclear weapons is in the high school physics textbook. How long have the aliens been on Earth? And they have captured so many people. Don't they even know the principle of nuclear weapons? You underestimate the aliens, don't you?"

Ye Han's mouth twitched, and he understood.

It is indeed as Wu Han said, the principle of nuclear bombs is not complicated at all. It is everywhere on the Internet, and even the internal structure of nuclear bombs can be found. It is not strange that aliens know it, but it is strange that they don't know it.

Wu Han said again: "But knowing it doesn't mean that you can make it... Do you think it's easy to make a nuclear bomb?"

This question is really hard to answer. Ye Han thought about it carefully before replying: "It is very difficult for individuals, and it can't be said to be easy for the country, but it shouldn't be very difficult for aliens, right?"

"What's not difficult? "Wu Han asked.

Ye Han said without thinking: "Mining and refining, aliens are good at this. The mines that we can't find, alien bugs can definitely find; refining is not a problem either, they can directly create a kind of bug, eat the ore into their stomachs, and excrete metal... No matter how poor the ore is, it has mining value in the hands of aliens!"

Wu Han said: "What you said is all right, but what about separation? I believe aliens can use bugs to refine metallic uranium, but do you think aliens can use bugs to separate isotopes?"

Ye Han was stunned: "It seems that they can't... But what if? "

The chemical properties of uranium 235 and uranium 238 are exactly the same. They cannot be separated by chemical methods at all, only physical methods can be used.

He is not very clear about how humans separate isotopes. There seem to be two methods, one is centrifugal separation, and the other seems to be called gaseous deposition.

No matter how you look at it, it is impossible to use insects to achieve these two methods, but what if aliens have methods that humans don't know?

Wu Han smiled understandingly: "Even if there is a chance, it is just to separate uranium 235, which is still far from a nuclear bomb! "

This doesn't need Wu Han to explain, Ye Han can figure it out by himself.

To put it simply, knowing does not mean being able to make it.

Early before the war, the principles of nuclear weapons were flying all over the sky, but how many countries have the ability to make nuclear weapons?

Nuclear weapons cannot be detonated by simple processing. They need the support of a full range of industrial systems. The processing accuracy alone can give aliens a headache for a while.

Aliens like to use insects no matter what they do, but they can't throw the finished uranium metal balls into the mouths of insects, and then grind them in the stomachs of insects, and when they are taken out, they will become qualified shapes, right?

From the current understanding, the only difficulty in stopping aliens is the separation of isotopes. In fact, if you think about it more deeply, there are still many difficulties that aliens need to solve.

For example, the structure of a nuclear bomb!

This thing can be found on the Internet, but it is just a simple schematic diagram, and there is no detail at all. It is very difficult to make a nuclear bomb with this thing.

Of course, there are simple ones, such as the gun-type structure used by "Little Boy".

This structure is so simple that it is very suitable for aliens to solve the problem of whether there are nuclear bombs or not - gun The disadvantages of the structure are great. Little Boy has 60 kilograms of nuclear charge, but in fact only one kilogram of uranium 235 fissions. It is extremely wasteful of nuclear materials and extremely dangerous. Even Americans only use it in experimental weapons.

As for more complex structures, haha, aliens have nowhere to find them. There is no content in this regard on the Internet or in textbooks. They can only be solved by aliens bit by bit.

Do aliens have the ability to solve these problems? Definitely not!

Can nuclear weapons be made without technology and only with theory? Isn't this a big lie?

Want to reach the current level of human beings? Haha, nowadays, human nuclear bombs have long been developed to the third generation. Basically, as much nuclear material as loaded will explode. The radiation residue after the nuclear explosion can be almost ignored, and the utilization efficiency of charge is very high.

However, there are only a few countries in the world that can achieve this level, not to mention the third-rate nuclear technology of North Korea and India, even some countries among the five major gangsters cannot reach this level.

Even if the aliens solve the principle problem, the processing of raw materials is still a stumbling block to prevent aliens from having nuclear weapons. How can they process the nuclear charge into the appropriate shape? With their fingers? With their teeth? Or continue to use giant insects?

Aliens are very good at playing with giant insects, but how can they use giant insects to process nuclear materials?

Ye Han wanted to laugh after thinking about it for a while... Imagine it, an alien puts a roughly processed uranium metal ball into the mouth of a giant insect, the giant insect eats it calmly, grinds it in its stomach, and finally pulls out a piece of uranium metal that meets the requirements... Can we not be ridiculous? Why don't we say that aliens can put uranium 235 into the stomach of the insect and directly make it into a moving nuclear bomb to kill the insect?

After figuring out the joints, Ye Han couldn't help but breathe a sigh of relief.

Seeing this, Wu Han asked with a smile: "How is it? Do you know why the aliens attacked Oak Ridge?"

"I figured it out!" Ye Han nodded, "The aliens' target may be nuclear weapons information, but more importantly, the personnel in the Oak Ridge laboratory!"

"Yes, that's what I mean. Those people are national treasures. There are at least a lot of them who can fight five divisions. Otherwise, why are the Americans so anxious!"

"Then the decision is..."

"Assist with all your strength and do your best to rescue the captured personnel. If they fall into the hands of aliens, the consequences will be disastrous."

"I understand... Uh, Chief, I still don't understand why the Americans are so stubborn? Why don't they know to withdraw the laboratory? If they just withdrew the people, there would not be today's situation!"

Today, sitting in front of the computer, I suddenly felt that it was meaningless to continue writing about Washington. I had to write something that everyone would be happy to read. In the end, I simply changed the map, so there are today's two chapters-I feel that the more complicated the content is, the more popular it will be. I don't know if my brothers have the same feeling... It took me four hours to code two chapters, which is really unique.
