A metaverse is a universe that transcends beyond our tangible reality. Networks of 3D virtual worlds focused on social connection by providing a more immersive interaction than the one you would get from a traditional website.To work properly, the metaverse needs far more than high-tech goggles and hype. The process to create an immersive world goes through many different layers that involve addressing every little aspect that makes us feel part of a real community beyond our physical space. This not only means a powerful network infrastructure but also real-time processing of virtual assets and detailed rendering models for the avatars, the ultimate expression of the self in the digital world. Compute power is the main resource of the metaverse and supercomputers its main engine. The last decade has seen a silent but wide expansion of data centres throughout the world and the HPC industry is stronger than ever and can bring new solutions.
