Create nuclear fusion at the start

“Guess?”

I don’t know if it’s an illusion, but from this moment on, the evening breeze became a little cool.

Li Hao nodded solemnly.

“That’s exactly why I’m looking for you. Dr. Lu, as the only person who has personally visited Crater 9527, tell me how the crater gave you an intuitive feeling. ”

Speaking of which, Xie Tianhe, who saved Lu Jie on the edge of the cliff at the top of the crater at a critical moment, can be regarded as a person who has been there. It’s just that he probably hasn’t looked at the crater as seriously as Lu Jie.

Lu Jie walked slowly forward while looking down at her elongated shadow on the ground.

“Well, it’s really very different from the pictures taken from the detector. I always felt that the crater was very special, it was located in a dense group of craters on the far side of the moon, which seemed very incongruous. ”

“Height. ”

Li Hao hit the nail on the head and said the special features of the 9527 crater.

Lu Jie nodded and said, “That’s right.” That crater was just too high. Although I had learned all of its data in the research room before, I could only feel the unusual height when I was there. ”

Li Hao said: “You have been committed to the study and analysis of unknown elements, especially in the past half a month, your laboratory has focused on the analysis and development of X108 under my instruction. You don’t seem to know much about the moon and craters. ”

Lu Jie nodded: “Yes, that’s not my professional direction.” Although I have spare time to make up for classes, it is only scratching the surface. ”

Li Hao raised his head and looked at the moon, which was getting brighter and brighter because of the night.

He said: “The moon, as the only planet on the earth, because of its mass, the gravitational force is only about one-sixth of that of the earth. This is a fact that has been proven. ”

Regarding this, Lu Jie has also experienced it firsthand. She still remembers the feeling of jumping 100 meters on the moon with the help of propulsion devices.

“With such a weak gravitational pull, it is impossible to grasp the atmosphere at all, so the atmosphere of the moon is almost equivalent to nothing. Without the protection of the atmosphere, all objects of the size that hit the Moon would hit the surface of the Moon directly, instead of being weakened by the atmosphere or burned by friction like the bodies that hit the Earth. ”

“I know that. Lu Jie said: “So compared to the earth, there are so many craters on the surface of the moon.” ”

“That’s right. Do you know which is the deepest crater on the moon?”

Lu Jie shook her head honestly.

Li Hao said slowly: “Because the back of the moon was just observed by humans, it doesn’t count for the time being. The largest known crater on the front side of the moon is the Gaglin crater, which is about 300 kilometers in diameter. ”

“300 km … What a crater it must have been from a celestial body…”

For a crater, this is undoubtedly already an astronomical amount.

Li Hao said: “Although I don’t know what the volume of the celestial body that hit the Gaglin crater is, someone has made calculations. If a 16-kilometer-diameter object travels at a speed of 50,000 kilometers per hour and hits the Earth, it will cause a crater to be 45 times the diameter of the object. ”

Lu Jie was even more surprised: “4 to 5 times? Then the celestial body that hit the Gagrin crater may have a diameter of more than 60 or even more than 70 kilometers? Oh my God, such a monster-level celestial body, I’m really glad it didn’t hit the earth…”

Thinking of such an asteroid hitting the earth, causing a nuclear winter and the extinction of life, Lu Jie couldn’t help but feel a chill down his spine.

But Li Hao’s next words made her feel even more incredible. _
