Wormholes are hypothetical tunnels through spacetime that act as cosmic shortcuts, connecting vastly separated points in the universe. First derived from Albert Einstein’s general theory of relativity, these structures could theoretically reduce journeys that take millions of years down to just hours.The Science Behind WormholesWormholes were first proposed in 1935 by physicists Albert Einstein and Nathan Rosen. They modeled these "tunnels" using the mathematics of black holes, which led to the concept historically known as an Einstein-Rosen Bridge.The Structure: A wormhole consists of two mouths (openings) connected by a constricted "throat".Travel and Time: By bypassing normal space, a wormhole could theoretically allow for interstellar travel or even function as a time machine, depending on how the entrances move relative to one another.
