Metaverse is a virtual world or universe that is created and sustained by the internet, where users can meet and create with one another in real-time through a personalized character or avatar. Metaverse uses open architecture, so anyone can create and build their own virtual spaces within the larger virtual environment, effectively building the metaverse itself. Metaverse has its origins in science fiction, but has gained popularity as advancements in technology have made it possible to create immersive virtual environments that replicate real-world experiences. These environments are often created using VR (virtual reality) or AR (augmented reality) technologies, which allow users to feel, move and interact as if they are truly present within the virtual space. Technology giants such as Nvidia, Meta, and Google are investing in the Metaverse, driving its popularity and creating new market opportunities.
