A wormhole is a hypothetical tunnel-like structure in space that connects two distant points in the universe. Imagine it as a shortcut through space and time, allowing for faster travel between two locations. If wormholes exist, they could potentially enable journeys across vast distances in a fraction of the time it would normally take, much like a tunnel through a mountain.
Scientists theorize that wormholes could be linked to the concepts of general relativity and black holes. However, they remain purely theoretical, as no one has ever observed a wormhole. Research continues, as understanding these cosmic phenomena could change our perception of the universe.
