Does a change in the trajectory of a person's life have a significant impact on the universe?

Han Xuan seems to be the dust in this universe, but these years have indeed caused unknown changes to the entire earth, and now this change has expanded to the solar system.

When he arrived at the meeting, he was surprised to find that everyone present was discussing an asteroid called "Apopel" and fearing that it would hit the earth.

NASA has warned that there are more than 4,000 asteroids around the earth that pose a threat to the earth, but the possibility of them actually hitting the earth is too small, and it may be tens of thousands, millions, tens of millions, or even hundreds of millions of years before a "destruction star" that truly threatens the safety of all life on the earth appears.

This threat really exists, the extinction of the dinosaurs is the best proof, human beings need to worry about not whether the planet will hit the earth, but when it will crash, so it has triggered a vigorous "interstellar migration" discussion, meteors, meteors and the like, are foreign objects hitting the earth, but the impact they can cause is too small, and the snow-capped mountain pasture has been smashed several times.

Seeing their sad faces, Han Xuan was a little confused in his heart, and guessed that something seemed to have happened that he didn't know.

Leaned over and asked Prime Minister Sisi Ismail, who had met at the airport in the morning, "Good evening, sir."

I'm sorry to ask, but what were you talking about, I heard that an asteroid is going to hit the Earth? ”

"Yes, we received official news from the United States in the afternoon that in 2013, an asteroid with a diameter of 400 meters may hit the Earth."

After hearing this, Han Xuan was startled, this is something that has not happened in his previous life, and he can let the US government release the news, indicating that the probability is very high, and he hurriedly asked: "Then what is the probability of impact?" ”

Prime Minister Sisi Ismail, who had not paid much attention to the news before, was stumped by the question, thought for a moment with a pensive expression, and said: "I don't know, I saw the numbers, but I didn't remember them clearly.

Feed! Our distinguished guest is here, and who of you knows the probability of the Apopfield asteroid hitting the Earth? ”

Disturbed by Prime Minister Ismail's voice, people greeted Han Xuan and Prince William respectively, and then talked about the numbers they had heard, some said one hundred, others said one in fifty, which confused Han Xuan and didn't know who to believe......

This important news successfully attracted Han Xuan's attention, and after greeting others at the scene, he came to the big camel that was still roasted by the blazing charcoal fire, smelled the fragrance and swallowed his saliva, took out his mobile phone and called Elon Musk, the only familiar cosmic madman.

The incident happened suddenly, and it didn't matter what time it was in the United States, and after the phone was connected, he asked: "I just heard about one thing, about the asteroid that may hit the earth, is it called Apopfield or something, how much do you know about it?" ”

"It's indeed called Apopel, little boss, and you've heard the news, too?

The noon news program on the television station reported that NASA had issued a level 5 hazard alert, and I had just finished talking to friends on the phone, and they told me that last week, a professor at the Massachusetts Institute of Technology had observed the threatening asteroid, and experts from all over the world had calculated that it was very dangerous.

According to the report of the Hawaii Observatory, the Apopfield asteroid is currently only about 0.05 astronomical units away from Earth, which is about 7.7 million kilometers.

If we continue to move forward at the current rate, we will reach the vicinity of the Earth around 2006.

According to calculations, it is expected to have a 1 in 380 probability of passing through the gravitational keyhole above the Earth and colliding with the Earth in seven years.

The calculated pre-estimate of the orbit is now around 8,000 kilometers, and the authenticity of this data has yet to be calculated, and as it gets closer to the Earth, the conclusions drawn will be more precise......"

The probability of 1 in 380 is high enough that people cannot ignore its existence.

The so-called "Earth's gravity keyhole" refers to a relatively small special gravitational area near the Earth's exterior, which can change the trajectory of the asteroid and may affect it and then impact the Earth.

Han Xuan understands these astronomical common sense, according to Musk, the planet should have passed by the earth, but the gravity keyhole happened to be near the area it passed through, which greatly increased the possibility of Apopfield hitting the earth.

According to past experience, an asteroid with a diameter of more than one kilometer collides with the Earth every hundreds of thousands of years, and an asteroid with a diameter of more than six kilometers collides with the Earth every hundreds of millions of years.

This time, humanity is facing a big guy, Apopel's size is not enough to pose a threat to the entire earth, but if it hits the earth, some areas will definitely be affected by it......

Han Xuan had a headache, pinched his eyebrows, and asked, "Why did you only find it until now?"

Also, where is the impact predicted? With a supercomputer, you should be able to calculate it, right? ”

"Years ago, someone noticed it approaching, but didn't pay attention to it at first.

This time, the professor at the Massachusetts Institute of Technology accidentally discovered that the possibility of it hitting the earth is extremely high, and now governments are already warning about it.

According to my friend, it is tentatively speculated that it may pass over the Siberian plains, pass over large cities such as New York, and after a week, finally crash into some part of North Africa.

For the time being, it is just an inference, and the uncertainty is too high, and it will take a few more years to get an accurate conclusion......"

Han Xuan thought to himself, no wonder there was so much commotion here tonight, it turned out that the Egyptians' nest might have been smashed by an asteroid, an asteroid with a diameter of more than 400 meters, the power it could cause was countless times more powerful than the atomic bomb explosion, and it was enough to destroy the entire city of Cairo.

He continued: "The probabilities have reached the number that needs to be alarmed, how do governments plan to respond to the possible crisis?" ”

"It's not clear yet.

More than an hour ago, the US Secretary of Defense urgently held a news briefing, saying that he would hold a summit meeting of various countries in the near future through the United Nations to discuss countermeasures.

In my opinion, if they really plan to deal with it, the most likely outcome is to restart the space shuttle program and carry a nuclear bomb to blast it.

But until the composition of the asteroid is understood, a nuclear attack may not be effective, and it must be intercepted outside the atmosphere, otherwise the damage caused will be no less than if it directly hits the Earth.

I remember that in 1994, when Comet Sumel-Levy 9 collided with Jupiter, the United Nations convened three safety meetings to prevent asteroids and comets.

Our experts from SpaceX are also going to study it and apply for permission to use the Fat Ding supercomputer, and you will hurry up and pass it, right? ”

Restarting the space shuttle project and using nuclear weapons to deal with asteroids, Han Xuan's eyes straightened when he heard these two things.

The first thought that comes to mind is "impossible", but if that asteroid is really a serious threat to Earth, it may be possible.

Nowadays, human technology is not yet developed, and in the face of these alien celestial bodies, the use of nuclear weapons seems to be the only option, and he continued: "Well, I will inform Executive Anthony that supercomputer resources will be used by you unconditionally.

Tell me first, if we do get to that point, it will take us a long time to prepare for it? I mean restarting the Space Shuttle program and launching a nuclear bomb into outer space to solve the troubles. ”

“…… At least ten years, the shuttles are almost rusty, the design drawings are still preserved, and it will take time to rebuild.

In addition, those space shuttles will carry super nuclear bombs, which must be fully safe, and two or three of them will have to be built to prevent accidents, and the cost will not be small. ”

Elon Musk's tone was particularly excited when he said this, and for super-universe fans, this kind of thing is simply great news.

An asteroid with a diameter of 400 meters, when approaching, people can predict the landing site, and then let the nearby people evacuate, maybe not many people will die, but it will inevitably have a serious impact on a certain area, and no one wants it to fall on the land of their own country.

After chatting for a while, and learning everything from Musk's mouth, Han Xuancai hung up the phone worriedly, raised his head and looked at the bright night sky, the stars were bright and extraordinarily wonderful, he knew that somewhere not far from the earth, there was a big trouble that was rapidly approaching, until it approached the earth in a few years.

According to his estimates, governments should not be expected to work together to deal with the crisis until the probability of an impact is reduced to a certain value.

The United States and Russia have so many nuclear bombs in their stockpiles that it is more than enough to blow up a small guy with a diameter of 400 meters, but the space shuttle project is too expensive, and I hope it can stay away from the earth.

Han Xuan confronted William and Anya, who were full of curiosity, and told them what he had heard......
