What is the stalk of WeChat circle of friends? Why are friends in the circle of friends?

Wechat friends circle broom mainly comes from a rumor, originally by a Twitter? Nasa broom challenge? The account was released, saying that NASA said that February 1 1 was the day when the gravity of the earth was the smallest, and it was also the only day when the broom could stand upright in this year. So people became very curious and began to try one after another, so they began to spread the virus on various platforms, and many people began to take pictures of their brooms.

What does it mean to erect a broom in a circle of friends? In fact, the vertical broom is just a beautiful lie. There is no official exact news on the Internet, but it has been heated in various platforms and forums. Moreover, CNN has recently started to spread rumors. In fact, it is mainly an old joke of 20 12. At that time, it was said that in the first few days of spring, when gravity was the smallest in a year, even the broom could stand upright.

But in fact, according to the data of Wired in the United States, both Venus, the nearest planet to the Earth, and Jupiter, the heaviest planet in the solar system, generate gravity below 10N, which is far less than the gravity generated by the Earth, and it is absolutely impossible to make the broom stand upright. So it is unscientific to say that gravity causes the broom to stand upright.

Some people think that it is caused by the gravity angle of the earth, but in fact, the inclination angle of the earth's rotation has been around 23.5 degrees, which is very stable. This is all because the earth has a huge satellite, that is, the moon. Like Mars, a planet with only a small satellite will of course have a great change in the inclination of its rotation. So having said that, how did the broom stand up?

Why can the broom stand up? In fact, it mainly depends on the support of the center of gravity, which means that anyone can stand up a broom or even an egg at any time as long as he finds the center of gravity. It has nothing to do with gravity at all. It needs a little more patience at most. Just like you put a broom sideways in your hand, you can always find a balanced position gradually.

Because the broom handle is too long, the center of gravity of the broom is basically located on the broom hair, so generally speaking, the thick broom hair is easier to stand because of its extremely concentrated center of gravity. If it is an old broom, the hair has split, so the center of gravity will be scattered or pulled further, which makes it difficult for the broom to stand up.
