What is the concept of metauniverse?

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

"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."

Therefore, the hyperuniverse is actually a virtual reality space based on modern technology and parallel to the real world.

With the VR helmet or brain-computer interface in reality, you can enter a virtual reality world, where you can socialize, compete, live and experience everything in the virtual world. This virtual reality space is the metauniverse.

In short, it is to build a virtual world that is no different from the real world based on modern scientific and technological equipment, in which we can live, socialize and work, which can be said to be a virtual reality space parallel to the real world.
