Defined Virtual WorldsModern virtual worlds are massive, simulated environments accessible via the World Wide Web. Virtual worlds can be classified into two distinct groups: “gaming” virtual worlds and “social” virtual worlds.

However, because their primary purpose is play and not communication, game worlds are generally not used for in-depth scientific discourse. To understand how virtual worlds are used to communicate science, we must look to an entirely different category of virtual worlds, called social virtual worlds. (Kavanaugh, 2001:496) Virtual social worlds developed to date include the online environments of There, Cyber ​​World and Second Life. As their name suggests, virtual social worlds lack the basic attributes of traditional games or video games: there are no points to score, no objectives or tasks to complete, no rules. to follow and no general game stories (Littlejohn, 1983: 80). .
