Metaverse is the name given to a collective virtual sharing space created by combining all digital worlds, that is, the fictional universe in which all digital worlds are located. According to many people, it will be possible to reach this Metaverse, which will be created in the future, through virtual reality or augmented reality.
The concept of metaverse was first mentioned in the novel Snow Crash by Neal Stephenson. In the novel, a three-dimensional virtual world with avatars of real people was called Metaverse. Apart from that, metaverse-like virtual worlds have been mentioned many times in the world of science fiction, some before Snow Crash.
The most recent example of this is the book Ready Player One, which was adapted for the big screen in 2018. In this book, people were able to spend time and interact in a digital world through virtual reality as they would in the real world. Another example that can be shown as similar to Metaverse can be the game called Second Life. In this game, which takes place in an internet-based virtual world, you can create your own avatar, interact with people and do things you do in real life virtually. Here, Metaverse is planned to be a similar digital universe.
