"Don't you have a girlfriend?"

"Nope."

"Don't you dislike my sister?"

"I like it."

"My sister has a lot of shortcomings. For example, I slept very poorly, and every day he would kick me under the bed; Also, she hates violence, and especially likes to knock me on the head, and I am almost stupid by her; And besides, she-"

"Eat more when you're hungry!" Ye Xin took out a small cake from her bag and stuffed it into Ye Jingjing's mouth, and then let her continue, her old bottom was exposed.

Jiang Lin smiled sullenly, then his eyes became serious, looked at Ye Xin's eyes, and said: "What are these shortcomings, I think it is much stronger than a person who will disappear in a short time." ”

"......" Ye Xin's heart tightened, avoiding his gaze and turning his head to the side.

Ye Jingjing scratched her head, she said while eating the small cake, "Disappear? Big brother, have you ever encountered this kind of thing? ”

"Hopefully I won't meet it."

"Jingjing, let's ignore him, I finally came to the planetarium, and I didn't come to visit him." Ye Xin pulled Ye Jingjing and was about to leave, but Ye Jingjing broke free of her hand, came to Jiang Lin's side, returned to the face of the fan girl, and said, "Big brother, you just said that a big meteorite can bring a devastating blow to the earth, is it really false?" ”

Ye Jingjing is not interested in Tianwen Mao, but she is still happy to be a small assistant, such an excellent big brother actually fell in love with her sister, it is really her ancestral tomb that is smoking, but she can't let her sister make Jiang Lin gone.

"Ye Jingjing, let's go."

"I don't want to. Sister, you can't give up such a precious learning opportunity, isn't it very meaningful to explore the mysteries of the universe? ”

Ye Xin: "......"

Stinky girl, I know that I have learned and used it well, and the country really didn't support you in vain.

Jiang Lin looked at Ye Xin, and then said: "Most space meteorites originate from asteroids, and after small meteorites enter the earth's atmosphere, they burn up because of friction with the atmosphere, that is, the meteors we see, generally speaking, they will burn up before they reach the ground." If a large asteroid enters the earth, it will cause a devastating blow to the life of the earth, for example, the dinosaurs 660 billion years ago may have been extinct because the asteroid hit the earth. ”

Ye Jingjing pinched her chin and nodded, and asked: "But no matter how big an asteroid is, it is far less big than the earth, at most, if you smash a hole on the earth, how can it not destroy the earth?" ”

"If there is really a lethal asteroid hitting the earth, the energy released at the moment of its impact is equivalent to a million times that of a nuclear bomb in the world, and the thermal radiation generated after the impact will quickly rush to all parts of the earth's surface, and the temperature can even reach the temperature of the sun's surface; In addition, due to the high temperature, many rocks are vaporized and liquefied into the atmosphere, and after cooling, transparent spherical stones are formed, and large-scale rock rain occurs on a global scale, in short, stones from the sky. ”

Ye Jingjing: "......"

I really don't know which one is more bullish than the stone in the sky and the knife in the sky.

After listening to Jiang Lin's narration, Ye Jingjing suddenly regretted asking him this question, the answer was too hardcore, and she couldn't resist it. An asteroid is so powerful that it doesn't let people live.

"Say a lot of things you don't understand, how can it be so serious." Ye Xin pursed his lips, dragged Ye Jingjing to him, and said, "Don't be afraid, he scares you." The Mayans did not predict the end of the world, indicating that it was too early for the destruction of the earth. ”
