Wormholes are some of the most exotic objects hypothesized to exist in the universe. They are the shortcuts through spacetimes between two locations, connected by a bridge called the wormhole’s throat, featuring an entrance and an exit. The idea of wormholes was first proposed by Ludwig Flamm in 1916 and later expanded upon by Albert Einstein and his colleague Nathan Rosen in 1935, leading to the term "Einstein-Rosen bridges" being used to refer to wormholes. The concept originates from Einstein’s general relativity. According to it, spacetime can be curved, and a wormhole is a place where the curvature of spacetime is so extreme that it creates a tunnel-like structure. These bridges can connect distant points within the same universe, as well as between different universes. However, no traversable wormhole has been found to date.
