The earliest definition of metauniverse is 1992. Neal stephenson, a famous American science fiction master, described the hyperuniverse in his novel Avalanche as follows:

"Put on headphones and eyepieces and find a connection terminal, and you can enter a virtual space simulated by a computer and parallel to the real world in the form of a virtual avatar."

Professor Chen Gang of Peking University and Dr. Dong Haoyu define the meta-universe like this:

"Metauniverse is a virtual world linked and created through scientific and technological means, which maps and interacts with the real world and has a digital living space with a new social system."

Meta-universe means that people in the real world have exclusive network identities in the meta-universe, forming a network world parallel to the real world.

Metauniverse is a digital space, an independent artificial space parallel to the real world, and a virtual reality network world supported by AR, VR, 3D and other technologies.

Generally speaking, the concept of a game is a bit like that. Enter the game, create your own virtual identity, and you can start playing happily, but this "game" is a bit too big.

Metauniverse is also the result of Internet inheritance and evolution, and it is the next stage of the Internet.

Metauniverse is not a simple virtual space, but puts the network, hardware terminals and users into a permanent and extensive virtual reality system, which includes both digital copies of the real world and creations of the virtual world.
