        abstract = {The metaverse represents the next evolutionary stage of the internet, transforming passive digital interaction into immersive, persistent, and shared three-dimensional environments. By integrating Virtual Reality (VR), Augmented Reality (AR), Artificial Intelligence (AI), blockchain, cloud computing, and high-speed networking, the metaverse enables real-time user interaction through digital avatars. While significant technological advancements have accelerated its development, challenges related to scalability, latency, interoperability, privacy, and governance remain critical barriers to widespread adoption. This unified survey consolidates research on metaverse architecture, real-time system design, hardware and software frameworks, metaverse engines, security concerns, and emerging application domains. Additionally, open research challenges and future directions are discussed to guide the development of scalable and sustainable immersive ecosystems},
