Popular science says oxygen is poisonous, and the whole internet scolds me for being sick

But at the same time.

An observer at NASA.

He was looking at data on various natural planets in the sky.

Use the most advanced astronomical observation systems to identify various large near-Earth asteroids and comets that may threaten the blue planet.

Directly establish a dynamic database.

Used to monitor and manage all celestial bodies that may fall on the blue planet.

Generally, their job is risk assessment and early warning.

Analyze the orbital parameters of those celestial bodies and predict the probability of impact.

Issue early warning information to superiors and authorities.

Generally speaking, we sometimes see a piece of news.

An asteroid or comet approaches the blue planet.

What is the probability of landing on the blue planet?

After all, human civilization is very fragile in the universe.

The dinosaur civilization was so powerful and prosperous.

It's just a meteorite.

Human civilization will naturally encounter similar situations.

In fact, there are countless craters on the blue planet.

If there wasn't a satellite like the moon here.

The blue planet will be hit by cosmic objects more often.

Only this time, NASA's monitors rubbed their eyes.

Originally, his position was a very leisurely one.

After watching Ye Zhen’s show, I wanted to check today’s monitoring data.

But just as he picked up his coffee, he saw a red message in the database.

I couldn't help but spit out the coffee I had just drunk.

"How is this possible!" he said in panic, holding onto the computer with the glowing screen.

Because it is shown here.

An asteroid numbered 2024 YR4 has a probability of about 2% to hit the blue planet.

This is an asteroid with a diameter of about 4 to 10 kilometers!
What is the concept of an asteroid of 4 to 10 kilometers?
The huge meteorite that destroyed the dinosaur civilization 6500 million years ago.

It’s only 10 kilometers!

So this is an asteroid that is comparable in magnitude to the one that wiped out the dinosaurs.

An impact would cause a massive global catastrophe.

It's like billions of nuclear bombs exploding simultaneously.

Tsunamis, earthquakes, global fires.

The dust cloud will last for decades and directly cover the entire blue planet.

This is definitely a disaster of annihilation level.

"No, I must report it quickly." The monitoring staff immediately passed the information up.

After reading this report, NASA’s superiors were so scared that they broke out in a cold sweat.

Even though the probability of 2% seems small.

Considering the database of asteroid impacts, this is already a very high probability.

How to describe it? This is even higher than the probability of getting gold when drawing a card.

Not just NASA.

This asteroid, code-named 2024 YR4, has been discovered by several astronomical observatories around the world.

Suddenly, the news was all about this asteroid.

Soon the whole world was interrupted by a piece of news.

Originally, everyone was still immersed in Ye Zhen's show.

Suddenly, I was interrupted by a piece of news.

"Ah? Another asteroid impact. Haven't there been a lot of similar news before?"

“Haven’t there been a lot of them before?”

"They keep saying this one will hit, that one will hit, but I've never seen a real collision."

"Fake news again, huh?"

Because a lot of similar news has been reported before.

For example, the former Bennu asteroid.

It is said that there is a possibility of hitting the blue planet.

Bennu asteroid, but the probability is only 0.037%.

Bennu

If it hits, it will release 12 billion tons of TNT equivalent energy.

There is also the very famous Planet Destroyer.

In 2004, the probability of an impact was predicted to be 2.7%, which is already very high.

It is known as the asteroid most likely to destroy the blue planet.

It caused panic at the time, but after prediction and correction, it was found to be just a false alarm.

But this time it's different.

The probability is already 2% just now.

You should know that the data of the Destroyer Planet also underwent many revisions.

The probability is increasing little by little.

Currently, our means of predicting celestial bodies are still very limited.

Because we need a lot of data and time to observe asteroids.

The closer it is to us, the more accurate the data we get.

So when the asteroid is not close to us.

The data obtained are often inconsistent.

It will be corrected over time.

There were several times when those asteroids passed very close to us.

But this also means.

When we can accurately calculate the probability of an asteroid impact.

We actually don't have any good solutions for asteroids.

You must have seen many similar scenes in movies.

The blue planet is about to be destroyed by an asteroid.

The world is thinking of various solutions.

In the end, without exception, nuclear bombs were used to change the flight direction of the asteroids.

Modify its orbit so that it does not directly hit the blue star.

Or else use more nuclear bombs to directly blow up the asteroid.

It becomes smaller fragments, so the harm is directly reduced to an acceptable level.

In addition, various thrusters are used to modify the flight direction of asteroids.

Generally these are the three techniques.

But all this takes time.

If it were in reality, many times we would discover asteroids.

In fact, there is no time left.

Because we need to come up with a method with the highest probability.

Which solution has the highest success rate?

Secondly, the execution process also takes time.

It is possible that during this process, the asteroid's orbit changed again.

Plans can't keep up with changes.

When you have finally done everything, you may find that your method has no effect at all.

It has no effect on asteroids at all.

When you want to change to another plan.

I found that there was no time left.

The only way is to let the asteroid hit the blue planet directly.

The news was released shortly afterwards.

Some astronomers began to pay attention to this asteroid code-named 2024 YR4.

They began calculating the probability of it hitting the blue planet.

“2.1%, 2.4%, 2.56%.”

The more they calculated, the more frightened they became.

As they pay more attention to this asteroid.

They discovered that the probability of an asteroid hitting the blue planet is actually increasing!

“This probability scares me.”

“Why is the probability so high?”

"Maybe if we get closer, the accuracy will improve?"

"Didn't the Destroyer Planet also go through this process before?"

"Yes, it's very likely that once it gets closer to us, the probability of getting accurate data will decrease."

These astronomers are very experienced.

This is the case with some asteroids, where the probability is calculated to be very high at the beginning.

As we get closer, the probability increases.

But when they confirmed it, they found that the probability of a collision was actually zero.

It’s just that there will be deviations in the previous calculations.

All the previous asteroid crises were just warnings.

It never actually happened.

They felt the same this time. (End of this chapter)
