The Science Fiction World of Xueba

Liu Xin said: "Professor Pang, since this is the case, please explain your thoughts!"

Pang Xuelin said: "In fact, this method is not difficult to say. The reason why it is difficult for us to detect asteroids with a diameter of less than 500 meters is that these asteroids have low apparent magnitudes (the higher the apparent magnitude The larger the brightness, the darker the brightness. For humans, the sun has the highest visual magnitude, which is -26.7, followed by the full moon, which is -12.6), and its ability to reflect sunlight is weak, and it also does not reflect radar waves. But We can try to enhance the signal feedback capabilities of these asteroids. For example, we can create large-scale artificial interstellar dust clouds in the space of 10 million kilometers near the Earth's flight path. These interstellar dust clouds have strong electromagnetic wave reflection characteristics. When an asteroid passes through the interstellar dust cloud, it will feedback a strong electromagnetic wave signal, and the signal value of an asteroid with a diameter of ten meters can even increase by more than a hundred times."

"In this way, as long as an asteroid passes through the interstellar dust cloud, it can leave a series of clear traces in space, just like people will leave a series of clear footprints when walking on the snow, so I call this The project is a snow project!"

After Pang Xuelin's words fell, the entire meeting room was quiet for a while, and soon fell into a hustle and bustle.

No one expected that Pang Xuelin would come up with such a wonderful plan.

Leaving aside the issue of whether this plan is realistically feasible, this idea alone is very valuable for discussion.

For a while, everyone was talking about it, and there was a heated debate on the feasibility of this plan. Some people supported it, while others opposed it.

Liu Xin and Seedorf looked at each other, with surprise flashing in their eyes.

Liu Xin had to pat the table and said: "Everyone, calm down, Professor Pang, I have a few questions for you about this plan. The first and most important point is that the artificial interstellar dust you mentioned Cloud materials, do we have such materials? Second, the earth’s voyage through the asteroid belt is close to 200 million kilometers, and the most dangerous voyage is about 50 million kilometers. If you follow the minimum requirements of the snow engineering plan you mentioned, We arrange an interstellar dust cloud with a diameter of 10 million kilometers within the most dangerous 50 million-kilometer flight path, and the required materials are an astronomical figure. Is the material reserve sufficient? How many spacecraft need to be deployed in such a wide space, have you considered these issues?"

The conference room became quiet again. Liu Xin undoubtedly reached the key point of the snow project, and everyone focused their attention on Pang Xuelin.

The plan he proposed is indeed quite ingenious, but the earth will pass through the asteroid belt in half a month. Whether human beings still have the time and ability to carry out such a huge project is indeed a big question.

Pang Xuelin smiled slightly, and was well prepared for these questions.

"Secretary-General Liu, regarding your first question, I can tell you clearly that we have such a material, that is, metal-based graphene nanocomposite material, which has a strong electromagnetic wave reflection effect, and is currently available in Jiangcheng. Mass production in the dungeon, as far as I know, the factory has more than two hundred tons of reserves. My idea is that we can wrap this material in a hydrogen bomb with a billion-ton equivalent, as long as the hydrogen bomb is delivered to the predetermined location , after the explosion of the hydrogen bomb, each ton of metal-based graphene nanocomposites can at least form an interstellar dust cloud with a diameter of more than 100,000 kilometers. In addition, we do not need to arrange such dust clouds with the radius of the earth's waterway, because the orbit of asteroids in the asteroid belt With one-way consistency, we can place such an interstellar dust cloud on the side of the Earth's shipping lane. The only question now is whether we have enough hydrogen bombs and enough vehicles to deliver the hydrogen bombs to the intended location."

Liu Xin narrowed his eyes slightly. He didn't expect that Pang Xuelin had even considered the specific implementation plan of this project.

Liu Xin said: "This question,

Let General Bell Arnold, Commander of the Space Fleet, answer. "

As he spoke, Liu Xin turned his gaze to the middle-aged man in the uniform of the Space Fleet sitting beside him.

Arnold said: "Professor Pang, I can tell you that our military has enough vehicles to deliver the metal-based graphene nanocomposites you mentioned. As for the hydrogen bomb, I think Flint is a suitable option. Our Flint can be directly transformed into a super hydrogen bomb with an equivalent of more than 100 million tons as long as it is slightly modified. Over the years, in order to prevent problems with planetary engines, we have stockpiled more than 20,000 flints. With the addition of modification, it can meet the needs of snow engineering.”

Pang Xuelin couldn't help being slightly taken aback, Flint is a black technology that only appeared in the movie "The Wandering Earth", and it is used to restart the planetary engine.

It's just that in the movie, it is not clearly stated what the flint is. Some people speculate on the Internet that it should be a thermonuclear bomb used to ignite the refusion planetary engine.

Pang Xuelin did not expect that this thing was actually a hydrogen bomb, and its yield was more than 100 million tons, which was twice the yield of the Tsar nuclear bomb dropped by the Soviet Union at the Xindi Island nuclear range, and it was almost as large as three A stellar hydrogen bomb in the body.

Liu Xin said: "In this case, do you have any opinions on the plan of the snow project?"

The meeting room became quiet again, everyone looked at me and I looked at you.

Soon, one of the astrophysicists took the lead: "I have no objection. Professor Pang's plan is indeed feasible. If it succeeds, it can greatly reduce the risk of the earth passing through the asteroid belt!"

"Neither do I, it's a genius idea!"

"I have no opinion……"

...

Soon, everyone at the meeting expressed their opinions.

Liu Xin said: "Since this is the case, let's focus the meeting on the discussion of the snow project!"

Then, scientists began to discuss the snow project.

Pang Xuelin only gave the general idea and feasible engineering plan of this plan. The specific engineering details naturally require scientists to plan and calculate them in detail.

For example, the specific location of the hydrogen bomb, how to detonate it, how to accurately calculate the orbit of the asteroid passing through the metal dust cloud, what role the space fleet needs to play in it, and so on.

Naturally, there is no need for Pang Xuelin to take action on these problems. The coalition government has a large team of scientists and engineers who can stand up to solve these problems.

Seeing that everyone in the conference room was engaged in a heated discussion, Liu Xin smiled and walked to Pang Xuelin's side, and said, "Xiao Pang, are you interested in having a chat with the old man?"

"my pleasure!"

Pang Xuelin nodded.
