Traversable Wormhole

A traversable wormhole is a theoretical tunnel in spacetime that connects two distant points in the universe, allowing for faster-than-light travel between them. Unlike black holes, which trap matter, traversable wormholes are envisioned as stable portals that could safely transport people or objects. They rely on hypothetical exotic matter with negative energy density to keep the tunnel open. While their existence is speculative and not confirmed by science, they are fascinating constructs in physics that could revolutionize space travel if proven possible.
