Portals are gateways or openings that connect two different places or dimensions. In science fiction and fantasy, they often allow characters to travel instantaneously between worlds, such as in stories featuring wormholes or magical doorways. These concepts capture the imagination by suggesting possibilities beyond our everyday experience. In technology, the term "portal" can refer to a website or platform that serves as a gateway to various resources and services. For example, a web portal might provide access to news, email, and social media, all in one place, making it easier for users to navigate the internet.
