Ormehul

Et ormehul, rumtidstunnel[1] eller Einstein-Rosen bro er en hypotetisk egenskab af rumtiden. Hermann Weyl opstillede i 1928 en hypotese om et fænomen, som er en slags tunnel, hvor det er muligt at rejse gennem rum og tid.[2][3] John Archibald Wheeler introducerede termen "wormhole" i 1957 om dette fænomen.[4]
Det er dog endnu ikke blevet bekræftet, at sådanne ormehuller eksisterer.[5]
Selvom det skulle vise sig, så er det meget usikkert om disse mystiske størrelser vil kunne bruges til f.eks. rejser til andre stjerner og galakser.[6]
Der findes forskere som mener at de kan laves med tilstrækkelig energi til rådighed.[7]

Wormhole: Wormholes are traversable connections between two universes or between two distant regions of the same universe. The wormhole shown here connects the place in front of the physical institutes of Tübingen university with the sand dunes near Boulogne sur Mer in the north of France. The image is calculated with 4D raytracing in the Morris Thorne wormhole metric , throat radius.
