Wormhole

Wormholes are hypothetical structures predicted by Einstein’s theory of general relativity that would connect two distant regions of spacetime through a tunnel-like geometry. In theory, they could act as shortcuts, allowing travel between far-apart locations much faster than light could travel through normal space.

However, all known wormhole solutions are either unstable or require forms of matter with unusual properties, such as negative energy, to remain open. No wormholes have ever been observed, and it is not known whether they can exist in nature.

Today, wormholes remain a mathematical possibility rather than a physical object, studied mainly to explore the limits of gravity and spacetime.
