Hello everyone, I am your good friend Ai Jin, thank you for your little hands who have made a fortune and pay attention to it, so that I don't get lost!!
Recently, when everyone browses videos or watches the news, do they all brush up on countries such as Germany and Argentina and begin to return mainland cultural relics? At first, I was puzzled, why did they suddenly find out with their conscience, click on the comment area of those videos to say Mach 31, I have never heard of it, I don't know what kind of unit this is, and I know that it is related to our Chang'e-6 after in-depth understanding.
As we all know, on June 25, the Chang'e-6 spacecraft returned to Earth from the far side of the moon and brought back two kilograms of lunar soil. And Chang'e-6 came back at a speed of Mach 31, (Mach 1 is 1 times the speed of sound, speed of sound: 340m/s, 1224km/h), 31 times I can't imagine how fast it is, anyway, someone gave me a science popularization, faster than the speed of the king of otters.
Why do you say that these countries want to take the initiative to return the mainland's cultural relics, and if you say that if you replace the Chang'e-6 aircraft with missiles, does it mean that the mainland can accurately find the location of a certain country on the moon and deliver "express" to it, and no national defense system can intercept it. As we all know, if a country publishes a study, it will ...... It's good that we know for ourselves.
In this regard, netizens also discussed:
When you are strong, others can be afraid
Anyway, Ultraman is here, and he has to eat me
It makes sense to say that [laughs] [laughs] [laughs]
I propose to build a museum to exhibit these artifacts
You know Yu Beichen [cover your face] [cover your face] [cover your face] [cover your face]
If you are strong, you don't have to look at other people's faces
Therefore, as long as I think that I am Chinese, I can wake up laughing in the middle of the night. Luckily, I graduated early, otherwise what would I do with my current physics problem [laugh] [laugh] [laugh].
