Wormholes
A wormhole is a hypothetical structure that connects two distant points in spacetime, like a tunnel through space and time. Imagine traveling from one location to another without crossing the space between them—a wormhole could theoretically allow this shortcut. Wormholes are based on solutions to Einstein's field equations and fit within the framework of general relativity, the theory that describes gravity. While wormholes are mathematically possible, they would need exotic properties to be traversable, meaning someone could actually travel through them. Scientists like physicist Kip Thorne have studied how wormholes might exist, though none have ever been observed. Wormholes matter because they represent a bridge between theoretical physics and imagination: they show what general relativity permits, explore the nature of spacetime itself, and have inspired decades of scientific research and popular culture.
