"A broken heart is like a shard of glass, the stupidity of love will never be restored......"

Chen Ya, who was setting up the tent, hummed a song comfortably, happy like a child, after all, in the wilderness, as long as there is food, he feels very happy, which is a simple happiness

And the netizens in the live broadcast room are the same, and even rolled up a barrage.

"Jumping grasshopper: Seeing Brother Ya's happy appearance, I remembered my childhood. ”

"Yin Yang Jianghu: Yes, there was no sexual need at that time, I didn't think about women, and I didn't need to think about anything. ”

"A pound of sugar: just thinking about today's cartoon, whether it's good or not!"

"He Xiaodu: Black Cat Sheriff, King Kong Gourd Baby, Salted Egg Superman Bump Man, Sailor Moon, Saint Seiya ......"

"Xue Mu Qianshan: Cut the chicken, cut the chicken, cut the chicken, cut the chicken!~ Be smart!"

"Dare to rob me of the title of King Frieza: hahaha, I've seen it all!"

......

Seeing the barrage, Chen Ya couldn't help but nod and smiled:

"I've seen it too. ”

In the sunset and dusk, Chen Ya chatted with netizens about childhood anecdotes, and gradually set up a temporary tent, and the sky gradually darkened.

Chen Ya lit up the glow stick, stuck it on the ground casually, and then came to the fire and sat down, looked at the food in the pot, and couldn't help swallowing:

"Simmer for another ten minutes, and you're ready to eat. ”

Saffron stewed Wang Ba is definitely a big supplement, but Chen Ya probably couldn't imagine that in the past ten minutes, unimaginable things have happened.

While waiting for the food to be cooked, Chen Ya looked up at the stars in the night sky as usual, and I have to say that the altitude is high, and the stars in the sky will become clearly visible.

Especially......

Occasionally, meteors can be found flashing in the night sky, so netizens in the live broadcast room also looked at the galaxy in the night.

"Actually, meteors are just passing by the Earth, or being pulled by the Earth's gravity......"

Maybe it was boring, Chen Ya briefly talked about the meteor, and then he was fascinated and wanted to scare netizens, so he continued:

"For human beings, meteors are just a rare sight and a medium to make wishes, but when meteoroids, large enough to a certain extent, they will become killers of the earth...... Near-Earth objects!"

Near-Earth objects?

Netizens were a little confused, but Chen Ya was energetic and said with great interest:

"Although most of the visible meteoroids are about the size of a grain of sand and weigh less than 1 gram, there are about 150 NEOs in our solar system with diameters greater than 10 kilometers......"

To put it simply, near-Earth objects are the general name for large meteors, meteorites, asteroids and the like in the solar system that are close to the Earth, usually between 100 meters and 10 kilometers in diameter.

Why are NEOs called Earth killers?

You must know that 65 million years ago in the White Age, the main culprit that led to the extinction of the dinosaurs was an asteroid with a diameter of about 10 kilometers that fell on the surface of the earth, that is, a near-Earth object.

After hitting the earth at that time, it caused an unprecedented explosion, which triggered a global crustal movement, a large-scale tsunami, continuous volcanic eruptions, dust filled the world, and the earth entered a cold winter.

Changes in the environment led to the complete extinction of the dinosaurs.

In the solar system, there are 150 near-Earth objects with a diameter of 10 kilometers, 2,000 near-Earth objects with a diameter of more than one kilometer, and 100,000 near-Earth objects with a diameter greater than 100 meters.

That is, the planet is in constant danger.

Chen Ya's words immediately frightened netizens, but fortunately, he smiled again:

"You don't have to worry, a near-Earth object with a diameter of more than 10 kilometers will collide with the Earth once in an average of about 100 million years......"

To put it simply, a near-Earth object with a diameter of about 1 km has a chance of hitting the Earth once every 100,000 years.

Near-Earth objects with a diameter of about 100 meters have a probability of hitting the Earth once every 10,000 years.

Therefore, there is no need to worry at all, after all, the time span is too long, even a 100-meter-diameter celestial body once every 10,000 years is almost painless for the earth.

But near-Earth objects of more than 1 kilometer are very terrifying, whether they hit land or hit the ocean, it will be a global catastrophe.

The netizens in the live broadcast room breathed a sigh of relief after listening to this story, while Chen Ya looked at the galaxy in the night sky and said:

"In any case, in the face of the threat of NEOs, we humans must not ignore it. ”

This is also one of the reasons why many countries are urgently developing the space industry, and mankind has never been absolutely safe.

Chen Ya boasted a lot of, and after getting too addicted, he was about to enjoy a sumptuous dinner, but suddenly the night sky lit up, and the Qinghai-Tibet Plateau, which was shrouded in night, was instantly illuminated like day.

But in the next second, night returned, and the Qinghai-Tibet Plateau entered darkness again.

"Flash, it's going to thunder?"

Chen Ya looked up at the night sky, could it be raining, right? Thinking like this in his heart, he didn't hear thunder, but instead appeared in the night, countless traces of meteors appeared.

It's a meteor shower!

In an instant, the netizens in the live broadcast room were collectively excited, and the barrage quickly scrolled.

"Wandering steppewolf: Oh my God! Meteor shower!

"Little Sun: (excited) People actually saw a meteor shower tonight!

"Bloody Xiaoqiang: Accompany you to see the meteor shower, I will fall on the earth and make your tears ......"

"Tangji Demingo: Hahaha, I suddenly remembered the Meteor Garden. ”

"Only you just say: Northeast F4, handsome to scum!"

"Su Mo Tsing Yi: What are you waiting for? Brother Ya hurry up and make a wish!"

......

Is it romantic?

What a special wish?

Chen Ya didn't have time to check the barrage at all, but stared at the meteor showers in the night sky, and found that those meteor showers with light trails did not look like they were passing by the earth.

Because meteors are very short-lived, they are basically flashing, but this meteor shower seems to be about to fall, and at the same time it is reminiscent of the previous lightning-like light.

Unexpectedly, he didn't hear the sound of thunder, Chen Ya's face changed greatly, and he made a terrifying guess in his heart at the moment.

"After the light, there is a meteor shower, can it be said that the light is ...... Nuke?"

So the meteor shower, will it not be a bombed NEO?

Thinking of this, Chen Ya was terrified, and the system also directly gave a prompt at this moment, confirming the guess in his heart.

[Drop!~ The host's guess is correct, just 1 minute ago, outside the Earth's atmosphere, a hydrogen bomb exploded. What else is it a hydrogen bomb?

Chen Ya's eyes widened, there are only a few countries with hydrogen bombs, and they need to use hydrogen bombs to smash the near-earth world that hit the earth, and the diameter is at least one kilometer.

And most importantly......

As the Qinghai-Tibet Plateau is the highest altitude area on the earth, Chen Ya can not only witness the meteor shower, but also show that the country that launched the hydrogen bomb is our motherland.

Huaxia is awesome!

These four words are about to come out.

But in the next second, the system gave a cold prompt again.

[Tips: There are still thirty seconds left for the meteorite meteorite group, and it is about to fall in the uninhabited area of Qiangtang, please take care of yourself]

"What's that?"

Chen Ya's scalp exploded, and he immediately looked at the night sky, only to see that the meteors that were falling rapidly were all fireballs, and the largest of them was fifty meters in diameter.

"System, I'll grass your grandma!"

Chen Ya roared in his heart, and immediately threw himself to the ground, and at the same time, he slapped three big mouths in a row and slapped him hard in the face, and said with remorse on his face:

"I'm just a crow's mouth!"

I just talked about near-Earth objects, but it turned out that there was an impact event once in 100,000 years, and now, near-Earth objects have been shattered, but the meteorite group formed by meteor showers still has a strong lethality.

Although it is said that falling in the Qiangtang no man's land will not cause any casualties.

But the key is......

Chen Ya is here, this is why people are asked to sit at home, and the pot comes from the sky!

At the same time, there is a long story about when the shattered NEO appeared, as well as the specific data and interception.

The camera needs to be switched to the Jiuquan Satellite Launch Base in Gansu, China, in the space command center on the 16th floor of the basement, a group of scientific researchers are collectively cheering.

This is another victory for China's aerospace industry!

......

[ps: Hahahaha! Lao Sha laughed crazy! This time, we are playing with a heartbeat!]
