The term "Megaverse" refers to a theoretical concept that encompasses multiple universes, or multiverses, each with its own distinct laws of physics, dimensions, and realities. It suggests an even larger framework than the multiverse, where countless universes exist simultaneously, potentially allowing for infinite variations of existence and experiences. In popular culture, the Megaverse is often explored in science fiction and fantasy narratives, where characters may travel between different universes or encounter alternate versions of themselves. This idea allows for creative storytelling and the exploration of complex themes, such as identity and the nature of reality.
