When an asteroid strikes, what else can we do but make the Earth wander?

We can also use existing technology to destroy this menacing asteroid. We all know that the current modern human race has developed to a terrifying point of "talking about the color change". It is said that the current nuclear ** stockpiles of all countries in the world, as long as one third of them are taken out, can destroy the world.

In the last century, the atomic bombs detonated by the United States in Hiroshima and Nagasaki in Japan directly dominated the trend of World War II. However, this "big **" is not the largest in the last century.

In 1968, the "Tunguska **" over Russia shocked the world. This time, according to scientists' speculation, there are at least 10,000 "fat people" and "little boys" equivalent. And the diameter of this asteroid is less than one percent compared to the "Big Mac" that destroyed the dinosaurs billions of years ago.

Just imagine how huge the threat of "asteroids" to the earth is. In 1178, five monks in England saw the scene of the "moon**" at night, according to the research of some modern scholars, it is also because the moon helps the earth resist the speeding "asteroids".

The movie "The Wandering Earth" released during the Spring Festival in 2018 sparked heated discussions among netizens across the country. If the asteroid is really about to hit the earth, what else can we do except "wander the earth" like the wolf warrior Wu Jing, Zhao Jinmai and others?

First of all, we can intercept asteroids by means of "nuclear explosion". However, this practice is quite polluting to space, and it may bring irreversible changes to the ecological environment. Moreover, the debris of the asteroid is also a great threat to the ground.

Lasers**, which are currently being studied intensively, can also be used to destroy asteroids in mid-air. Perhaps, we can also use gravity to carry asteroids away from Earth's orbit by launching spacecraft.

Of course, if none of this can be done, perhaps human civilization will have to "wander the earth".

When an asteroid strikes, we can use a nuclear explosion to deflect the asteroid's orbit or destroy the internal structure of the asteroid, or we can use other vehicles to fly at high speed to impact the asteroid and reduce the impact of the asteroid.

It may be possible to calculate the orbit of the planet and then launch a vehicle that collides with the asteroid in advance to destroy the asteroid or change its orbit.

The movie The Wandering Earth tells such a story, when an asteroid hits, in addition to letting the Earth wander, we can also choose to protect the Earth, maybe by that time we will have such technology.

The brain hole is a bit big, with the current science and technology, can human beings change the trajectory of the earth?

Asteroid 2020 QG orbit change.

On August 16, the asteroid, code-named 2020 QG, flew by the Earth, reaching as close as 2,950 kilometers above the Indian Ocean. This makes 2020 QG the closest asteroid to Earth in recent years.

Although the SUV-sized asteroid did not hit the Earth. Its trajectory has been significantly altered – about 45°.

"It's cool to see an asteroid like this so close to Earth," said Paul Kedas, director of NASA's Jet Propulsion Laboratory Near-Earth Object Research Center. Because we can clearly see how the Earth's gravity causes its trajectory to bend. ”

The 2020 QG is about 3 to 6 meters wide and flies at a speed of about 10,000 kilometers per hour.

It's the bigger asteroids that pose the real threat. Astronomers believe that the asteroid that caused the extinction of the dinosaurs was about 10 kilometers wide.

Currently, astronomers are tracking 95% of NEOs, classifying objects with a width of more than 140 meters. If they collide with Earth, such NEOs are thought to cause a large-scale catastrophe.

Astronomers hope that in the future, "gravity tractors" will be used to guide asteroids that may pose a threat to Earth.

These "gravity tractors" are, to put it simply, launch artificial instruments to re-orbit asteroids.

However, it may take months or even years for humans to do the "orbit change" that the earth can do in an instant.

In the vast starry universe, the earth where human beings live is just a slightly special planet, because on this planet there is an intelligent creature human beings, so the special nature of the earth lies in this, and the earth has become the only planet in the entire solar system that gives birth to life. 65 million years ago, the earth suffered an asteroid impact on the earth, and this impact directly caused the destruction of the dinosaurs at that time. So if the little star strikes again, what should we do as earthlings?

What can be done? The answer is as follows. <>

1. Use missiles to directly destroy these asteroids. First of all, the first point is that our current human beings are different from the original dinosaurs, that is, we have a quality guarantee, which is a missile. These missiles are enough to destroy many asteroids, so that these asteroids will hit the Earth and no longer change the Earth's climate.

It will not expose human beings to the threat of dinosaurs at that time, which is the strength of human beings, which is also a difference between intelligent and non-intelligent beings. <>

Second, humans can carry out planetary migrations before impact. Secondly, another answer is that we can move the planet away before the asteroid hits the Earth. Such a plan is now complete.

It's still far away, but when an asteroid hits the Earth, a crisis like that prompts us to complete it. And you, as a human being, will always bring out your highest potential when danger comes. And why we didn't study the planetary migration plan is because these big countries are playing games with each other, and when danger comes, they will huddle together.

3. Establish a sanctuary in the interior of the earth. Finally, when an asteroid hits the Earth, we can also create a protective lock inside the Earth. Although these protections cannot stop the little stars from harming our earth, for us humans, they can greatly protect or preserve the last spark of human beings.

We can let the earth wander, find a certain way to avoid danger, and we can also hit it, but if it doesn't work, we can still implement it, which is okay.

The asteroid doesn't have much of an impact on the Earth, and we probably don't feel it at all. Because there is an atmosphere on the outside of the Earth, it will help us block or reduce the subduction force of the planet's impact on the Earth.

We can send spacecraft with a nuclear ** to smash asteroids in outer space so as not to harm Earth.

An asteroid is coming, and we need to wait. I can't go to ** on earth, I'm just asking for more blessings. It's also some of the best practices that give us a lot of strength.

All we ordinary people can do is to hide, and scientists can use the vehicle to speed up and then crash into the asteroid, without destroying its structure, change its speed, and thus change the asteroid's orbit.

With our current level of technology, we can neither change the orbit of the earth nor the trajectory of an asteroid, so when an asteroid strikes, we can only avoid it by judging where the asteroid lands.

An asteroid will pass over the Earth and possibly threaten, how can we defend against it?
