The laboratory in the hands of the people of the United States must not be limited to Oak Ridge, but the aliens will attack this place if they don't sneak attack other places, do you need to talk about what the idea is?

Thinking of this, Ye Han's whole person was not good: "Chief, aliens want to build nuclear weapons, they definitely want to build nuclear weapons!" ”

Wu Han's performance was more calm than Ye Han imagined: "Haven't they wanted to build nuclear weapons for a day or two, as for such a fuss?" ”

This sentence was like a heavy rest, interrupting Ye Han's intense emotions at once, 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?" How? Can't figure it out? ”

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

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

"You know what?" Ye Han was a little stupid. “

"Of course I do." Wu Han's words shook Ye Han's mind, and the whole person was so shocked that he couldn't speak.

"Is it strange?" Wu Han smiled a little badly, "You don't want to think about it, there is the principle of nuclear weapons in high school physics books, how long have aliens been on Earth?" With so many people captive, can't you even grasp the principle of nuclear weapons? You're underestimating aliens, aren't you? ”

The corners of Ye Han's mouth twitched, and he also understood.

Indeed, just like Wu Han said, the principle of the nuclear bomb is not complicated at all, the Internet is overwhelming, and even the internal structure of the nuclear bomb can be found.

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

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

"Where is it not difficult?" Wu Han asked.

Ye Han didn't want to think about it and said: "Mining and refining, aliens are good at this, the mines we can't find, alien insects will definitely be able to find them; Refining is not a problem, they can directly make a kind of bug, eat the ore in the stomach, and the metal is discharged...... No matter how poor the mines are, they are worth mining in the hands of aliens! ”

Wu Han said: "What you said is right, but what about separation? I believe that aliens can use bugs to refine uranium metal, but do you think aliens can use bugs to isotope isotopes? ”

Ye Handeng was stunned: "It seems that it can't be ...... But what if? ”

The chemical properties of uranium-235 and uranium-238 are completely identical, and they cannot be separated by chemical methods at all, only by physical means.

He doesn't know very well how humans isotope isotopes, and it seems that there are two methods, one is centrifugal separation, and the other seems to be called gaseous deposition.

No matter how you look at it, you can't use bugs to achieve either method, but what if the aliens have a means that humans don't know?

Wu Han smiled understandingly: "Even if there is a case, it is to separate uranium-235, and it is still far from the nuclear bomb!" ”

This doesn't need to be explained by Wu Han, Ye Han can think it out by himself.

To put it simply, knowing is not the same as being able to make it.

Long before the war, the principle of nuclear weapons was flying all over the sky, but how many countries had the ability to create nuclear weapons?

Nuclear weapons cannot be detonated by simple processing, they need the support of a full range of industrial systems, and a single processing accuracy can give aliens a headache for a while.

Aliens like to use bugs for everything, but they can't just throw the finished uranium metal ball into the bug's mouth, then polish it in the bug's belly, and when they take it out, it will turn into a good shape, right?

Judging from the current situation, the only difficulty in blocking aliens is the separation of isotopes, in fact, if you think about it deeply, there are still many difficulties that aliens need to solve.

For example, the structure of a nuclear bomb!

You can find this thing on the Internet, but it's just a simple schematic diagram, and you can't find the details at all, and it's not ordinary to build a nuclear bomb with this little thing.

Of course, there are also simple ones, such as the gun-type structure used by the "little boy".

This structure is outrageously simple, and it is very suitable for aliens to solve the problem of whether there is a nuclear bomb - the gun structure has great drawbacks, the little boy has 60 kilograms of nuclear charge, but in fact there is only one kilogram of uranium-235 fission, which is extremely wasteful of nuclear materials, not to mention, it is also particularly dangerous, and even the people of the United States only use it on test weapons.

As for the more complex structure, hehe, aliens have nowhere to find it, whether it is on the Internet or in textbooks, there is no such content, and it can only be solved by aliens little by little.

Do aliens have what it takes to solve these problems? Definitely not!

Can you build nuclear weapons without technology, empty theories? Isn't this a capital, and what?

Want to reach the current level of humanity? Hehe, today's human nuclear bombs have long been developed to the third generation, basically as many nuclear materials as they are loaded, the radiation residue after the nuclear explosion is almost negligible, and the utilization efficiency of the charge is not generally 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 Beibang and Asan, even some countries in the five hooligans cannot reach this level.

Take 10,000 steps back and say, even if the aliens solve the problem of principle, the processing of raw materials is still an obstacle to the aliens from possessing nuclear weapons [31 Update fast] tigers, what methods can they use to process the nuclear charge into a suitable shape and buckle it with their fingers? Biting with your teeth? Or continue to exploit giant bugs?

Aliens are playing giant insects to the core, but how to use giant insects to process nuclear materials?

After thinking about it a little, Ye Han wanted to laugh...... Think about it, an alien stuffed a rough uranium metal ball into the mouth of a giant insect, and the giant insect calmly ate it, polished it in its stomach, and finally pulled out a piece of uranium metal that met the requirements completely...... Can we stop? Why don't you say that aliens can take uranium-235 plug worms into the stomach and directly make them into moving nuclear bomb suicide worms?

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

Seeing this, Wu Han smiled and asked, "How is it?" Do you know why the aliens attacked Oak Ridge? ”

"Got it!" Ye Han nodded, "The aliens' target may be nuclear weapon data, but more importantly, the personnel in the Oak Ridge Laboratory!" ”

"Yes, that's what it means, those people are all national treasures, and there are a lot of the top five divisions, otherwise why are the people of the United States so anxious!"

"The decision above is ......"

"Assist with all your might, do your best to free the captives, if they fall into the hands of aliens, the consequences will be unimaginable."

"Understood...... Uh, chief, I still don't understand, why is the heart of the United States so big? Why didn't you know to remove the lab? It's not like this today just to evacuate people! ”
