A Wormhole (also known as an Einstein-Rosen Bridge) is a special portal or tunnel created to quickly travel from one place to another, no matter the distance between them. Most wormholes in the known universe were created by the Bifrost Bridge or the Tesseract. In physics, a wormhole is a hypothetical topological feature of spacetime that would be, fundamentally, a "shortcut" through spacetime.
Thor and other Asgardians used the Bifrost Bridge to make wormholes to travel to other places. In 1945, when Johann Schmidt took the Tesseract with his bare hand, he was transported by a wormhole to Vormir. At the beginning of the 21st century, Jane Foster was researching wormholes and studied the possibility of them.
During the 2013 Convergence, many wormholes opened up around the Nine Realms, all coming together in Greenwich. Malekith attempted to use the Aether to destroy reality with these wormholes, but was stopped by Thor, Darcy Lewis, Jane Foster, and Erik Selvig.
Since ancient times, the group that would later be known as HYDRA kept a Kree artifact: a Monolith that was originally intended to defeat Inhumans, and regularly sent human sacrifices through it to another planet to appease an exiled but powerful Inhuman. During the War against the Inhumans, the Inhumans become aware that S.H.I.E.L.D. had the Monolith and attempted to recover and destroy it. After the war, S.H.I.E.L.D. kept it from the crippled Inhuman population of Afterlife. Agent Jemma Simmons was swallowed by the Monolith, quickly prompting her partner Leo Fitz to track down every myth and every possibility surrounding the Monolith. Eventually with the help of the Asgardian Elliot Randolph, S.H.I.E.L.D. managed to retrieve Jemma Simmons and caused the stone to explode. However, Gideon Malick procured different fragments and, using the instruments within an English castle, create a wormhole for Grant Ward to retrieve Hive. Chasing Ward, Phil Coulson entered the Wormhole also. Ultimately, S.H.I.E.L.D. led an Attack on the HYDRA Castle, retrieved Coulson and Fitz, who was also sent through the Wormhole to Maveth, and destroyed the castle; however, Hive traveled through the Wormhole, using the corpse of Ward.
When Thor and Loki tried to escape Hela through the Bifrost Bridge, she managed to throw the two out of it and they both were caught in wormholes which brought them to Sakaar. Later, the two, together with Hulk and Valkyrie, escaped the planet by flying the Commodore through Sakaar's largest wormhole, the Devil's Anus.
