What can we do when an asteroid hits?

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.

Doing so would be very expensive.

What's more, it's unnecessary. The population is expected to reach between 9 and 12 billion. We can already feed so many people if we need to.

In addition, we do not "deplete" the planet's natural resources, such as water. We do not consume minerals such as iron, aluminum, cobalt or titanium. These minerals do not leave the earth. And there are a lot of these that can be solved simply.

As energy becomes cheaper and better, and robotics advances, all of these minerals will be cost-effective.

One exception is fossil fuels. These can't, but we have hundreds of years of sediment, and we shouldn't need to talk about them to produce energy for the next century.

Can space mining save our planet? If so, how? If not, why not?

No. It's very expensive, and it always will be. The idea of using rockets to take bulk materials from an asteroid millions of kilometers away and deliver them back to Earth is pure fantasy. It's always higher than the acres of pants that have been dug up from the ground or landfills here.

And, in fact, it is not iron deficiency that threatens the planet. This is a surplus of carbon dioxide. Space mining does not solve this problem at all.
