Wormhole
A hypothetical topological feature of spacetime creating a shortcut connecting two separate points in space and time.
Governing formula
ds² = -c² dt² + dl² + (r₀² + l²) (dθ² + sin²θ dφ²)
SI unit
Einstein-Rosen Bridge Topology
In depth
A theoretical solution to the Einstein field equations (Einstein-Rosen bridge). Traversable wormholes require exotic negative-energy matter (T_μν violation) to hold the wormhole throat open against gravitational collapse.
Examples in the real world
Theoretical models of traversable Morris-Thorne wormholes in theoretical astrophysics and science fiction.
