People don’t seem to care much about the future world described in the sci-fi movie The Matrix, but a recent news released on the Meta platform has made people curious about the future world. According to Forbes, a virtual community named Game Free is building a virtual world-"Metauniverse". It has been established for more than ten years, but it is relatively simple compared with the world in the Matrix. What is the magic of meta-universe? Has it become a reality now?

I. Future Society
The idea of "Metauniverse", first put forward by Meta Company, is an expression way to turn people’s vision of the future society into reality. In the setting of X-Men, Professor X has special devices and abilities in real life, and can breathe and move freely, but he can’t turn his control into a real society. The reality is not infinitely close, but gradually close to the ideal society. That is to say, the "infinite approach" pursued by the X-Men is not realistic in real life: it is impossible to turn one person into another; Unable to control human behavior; Unable to control the direction of people’s actions in reality … eventually led to the X-Men being abandoned by the world. If the X-Men movies are sorted out, it is found that the movies have a clear vision for the future society, then the meta-universe will be closer to the real state in reality: on the one hand, the meta-universe, as a virtual space, can be infinitely connected to the real world; On the other hand, Metauniverse will become the key "cornerstone" for building the infrastructure of human society … So what will human society become in the future?

Second, intelligent hardware
The universe is not only a game world, but also a technology. In MetaUniverse, through various virtual carriers such as games and videos, MetaUniverse players can be immersed in it, which is not only a space for games and entertainment, but also an interactive space for knowledge, skills and contacts. There is a kind of meta-universe in a special sense, which is a "virtual life" mode in which the virtual world and the real world merge, influence, blend, promote and expand with each other. It is a place where people can exchange and interact with each other, acquire knowledge and skills and cultivate friendship in this virtual world. For users, Metauniverse makes itself a "human" character-this is the experience they need in games and the real world. For hardware equipment manufacturers, it is the performance of the product itself besides ensuring entertainment, interaction and other functions.

Third, artificial intelligence
As the core of scientific and technological innovation, artificial intelligence will gradually get more applications in the meta-universe. With the help of human beings, artificial intelligence has developed from relying on single software and single function in the past to the present artificial intelligence. In the future, artificial intelligence will be more dependent on computing power. For example, driverless cars are an attempt to realize barrier-free travel in the meta-universe. Starting from the progress in the field of driverless cars, this paper explores the possible forms that driverless cars may appear in the meta-universe, hoping to provide more exploration space for the meta-universe. It is foreseeable that artificial intelligence will play an important role in the meta-universe in the future.

IV. Conclusion.
With the rise of meta-universe, virtual world has been given more and deeper meanings, and the application of science and technology by human beings has changed from passive acceptance to active creation. At the same time, the lifestyle and experience provided by the virtual world in the meta-universe have greatly enriched human thinking and feelings, and made people interested in a new thing. However, with the development and innovation of technology, this trend will gradually become stable. But we believe that technology is always a double-edged sword. It can bring convenience and benefits to human beings, but it may also bring harm to human beings. Like the future world described in science fiction movies, human beings are sleeping in a dormant warehouse made of machines, and their brains are linked to the meta-universe world, so they live falsely.

Boys, right -handed horizontal board, single -line exercises on the front and backhand.

1. Positive hand. The plate shape is stable, the hitting time is reasonable, and the proportion of impact and friction is quite good. The first thing that needs to be adjusted is the shape, the big arm is started, and now it is too close to the body’s torso, causing the big arm tension, and the continuous shoulders are raised.

It is best to swing with bare hands to solve it. At the same time, the front arm is opened horizontally a little more. In this way, the focus of the exchange is adjusted together. My legs, but I estimate that the distance between my feet is close. That is to say, we comprehensively govern during waving,Open your feet properly, the knee is slightly bent, and the structure will be much more reasonable.It is best to use multi -ball to adjust the action with more effort. It is not impossible to use a single ball. The requirements for the sparrows are relatively high. Of course, you can do a single ball.

2. Affairs. This video is shot well, and there are angle changes, and it will be much more comprehensive.

The child is stable and the action structure is quite stable. The proportion of playing and rubbing in the ball is quite good. This coach is a bit level, at least, it is quite satisfactory. You can stand some properly at your feet, and the sense of stability will be much better.

In addition, there is a detail that he must stand in front of him with his left foot. Sometimes he comes out of his right foot. At the same time, the left foot heel is twisted on the ground. This is not possible. Can you remind him that when hitting the backhand, the left forearm of the left arm is placed near the left waist, and the height on the table is very helpful to the body balance.

At this age, the practice of training, and the number of training hours, the ball skills will rise very fast.
