Qin Feng took the tablet that Lu Qiujian handed him, and in the open folder were several Hollywood science fiction blockbusters, including "Meteorite Collision" directed by Michael Bay and starring Bruce Willis and Ben Affleck, "The Great Collision of Heaven and Earth", also released in 1998 and starring Robert Duvall and Morgan Freeman, as well as "The Star Paratrooper" adapted from the classic novel "Star Paratroopers" by Robert Heinlein, a famous science fiction writer in the United States. Starship and more!

"Meteorite Crash" tells the story of NASA's discovery of a meteorite the size of Texas that is heading towards Earth and will hit Earth in 18 days. In order to cope with this huge disaster, the people of the United States came up with a way, they found the best oil drillers from all over the world, transported them to the meteorite, and asked them to make a hole in the meteorite to put a nuclear bomb in it, and then destroy the meteorite! After staging a thrilling story, Bruce Willis stayed on the meteorite to manually detonate the nuclear bomb, sacrificing himself to save mankind.

The plot of "Heaven and Earth Collision" is similar to the previous one, the same asteroid is about to hit the earth, and then humans send a spaceship to destroy the asteroid with a nuclear bomb, and finally sacrifice the entire spaceship team to keep mankind safe.

At the beginning of "Starfleet", humanity was also attacked by the Zerg meteorite, and many large cities around the world were razed to the ground under the impact of the meteorite!

There are several other films like this, and a common feature of these films is that meteorites have become the biggest threat to human security, and indeed there is such a possibility in reality! For example, the Tunguska explosion more than 100 years ago, for example, the extinction of the dinosaurs 65 million years ago!

But in response to the solutions proposed in these Hollywood films, whether it is drilling and placing a nuclear bomb, or a spaceship hitting a meteorite, Lu Qiujian only has four words to evaluate the damn retarded!

As we all know, the nuclear bomb is a powerful weapon, and if the structure of the meteorite is relatively loose, under the power of the nuclear bomb, the meteorite will definitely be blown into pieces, so you can't guarantee how many of the remaining fragments will still fall on the earth! Mankind will also suffer a huge disaster! This is the case in "The Great Collision of Heaven and Earth", the first nuclear bomb blew the meteorite in half, and the smaller half still crashed on the earth, destroying several cities! And according to Bruce Willis's approach, detonating a nuclear bomb in the core of a meteorite will only cause more fragments!

So is there a better way to solve this problem? Of course, scientists have already given many answers, and nuclear bombs are just one of them.

A more scientific approach is to detonate a nuclear bomb near an asteroid, and the intense radiation produced by the explosion can evaporate part of the asteroid's surface, causing it to eject surface material into space. This jet is like installing an infinite number of miniature rockets on an asteroid to change its orbit. The universe is so vast that an asteroid hitting the earth is almost equivalent to a bullet from hundreds of meters away trying to hit a small house, as long as the angle is slightly changed, the bullet will deviate from the predetermined orbit and pass by the side of the house, and the same is true for meteorites!

NASA has also proposed a kinetic interceptor, which is like firing a spinning bowling ball with a pellet gun and causing the asteroid to deflect from its impact trajectory. According to NASA calculations, if the bowling ball were launched 20 years before the predicted impact, an impact of 1.6 kilometers per hour would be enough to deflect the asteroid 273,500 kilometers from its original orbit, enough to deflect the asteroid from Earth's orbit.

Another option is to send a spacecraft to install giant solar sails for the asteroid, which uses the strong solar wind to deflect the asteroid from its original orbit and prevent it from hitting Earth. In some of the ideas put forward by scientists, the solar sail can even be adjusted to allow it to be remotely controlled on a certain range of dù, and to achieve the purpose of accurately controlling the trajectory of the asteroid on a certain range of dù! However, the asteroid is always in a state of tumbling and rotating, and even if we can send an unmanned spacecraft to land on the asteroid, it is difficult for us to erect a solar sail that is enough to change its orbit.

The brain-wrenching NASA has also proposed an even more exaggerated plan, using a carbon fiber net weighing about 249 kilograms is enough to change the orbit of an incoming asteroid like Destroyer. The material used in this skynet can act as a solar sail, increasing the amount of solar radiation absorbed and emitted by the asteroid. This approach would allow Anglosphere to move away from Earth's orbit when it returns to Earth in 2036.

Again, this catastrophe could have been avoided by using Archimedes' approach to enemy fleets by using a giant mirror to gather sunlight and heat a small area of the asteroid's surface, causing it to spew steam outward. This ejection of material creates a thrust that changes the asteroid's orbit.

It is also possible to make a hole in an asteroid like Bruce Willis, but without a nuclear bomb, we can place a rocket in that location, and then ignite the rocket, and use the thrust of the rocket to change the orbit of the asteroid, and on a cosmic scale, even just changing the direction of the asteroid for one degree is enough to keep the Earth safe! There is no need for Bruce Willis to sacrifice himself.

We can also send a flying machine to rub an asteroid at a key angle, like a chipping ball in snooker, and subtly change its flight trajectory; there are too many ways like this! Using a nuclear bomb is no good except being more violent and speeding up the production of adrenaline, and of course, Hollywood blockbusters want this effect! If you make a film of solar sails changing the orbit of an asteroid, this visual effect will definitely make the investment company lose its pants.

Lu Qiujian was thinking about various methods to destroy asteroids, and at the same time paying attention to Qin Feng's expression! I saw that Qin Feng's brows furrowed more and more tightly the more he looked at it, and when he was about to finish the last movie, he asked, "Professor Lu, do you want to use this method to sink the aircraft carrier of the United States?"

"Yes! There are many ways to control the trajectory of meteorites! As long as we can be precise enough! We can completely control an asteroid to crash at the location we need according to our requirements!" Lu Qiujian explained those methods.

"Oh, what method are you going to use?nuclear bomb or solar sail?But this kind of movement seems to be a bit big, right?We will be hostile to the whole world!" Qin Feng disagreed.

"No, I just need a can of paint!" Lu Qiujian smiled. (To be continued.) )
