The metaverse is a virtual world that allows users to interact with each other or objects in real-time using their avatars by breaking down all real-world physical obstacles. It has been applied to various domains, such as video games, art, retail, education, healthcare, manufacturing, social, and many more. This paper investigates the Metaverse for Industry 4.0 and beyond applications in terms of opportunities and challenges. It analyses opportunities of the Metaverse for different aspects, from technical, economic, and educational to social. This study also discussed main challenges in Metaverse, such as data security and privacy, decentralization, interoperability, and resource management.
