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]
