Wormholes have been defined both geometrically and topologically. [further explanation needed] From a topological point of view, an intra-universe wormhole (a wormhole between two points in the same universe) is a compact region of spacetime whose boundary is topologically trivial, but whose interior is not simply connected.
In 1990, Wheeler suggested that information is fundamental to the physics of the universe. According to this "it from bit" doctrine, all things physical are information-theoretic in origin: Wheeler: It from bit.
Nathan Rosen (Hebrew: נתן רוזן; March 22, 1909 – December 18, 1995) was an American and Israeli physicist noted for his study on the structure of the hydrogen molecule and his collaboration with Albert Einstein and Boris Podolsky on entangled wave functions and the EPR paradox.
Portrait of Paul Dirac by Clara Ewald, 1939. Paul Adrien Maurice Dirac (/ d ɪ ˈ r æ k / dih-RAK; 8 August 1902 – 20 October 1984) was an English theoretical physicist who is considered to be one of the founders of quantum mechanics. [6] [7] Dirac laid the foundations for both quantum electrodynamics and quantum field theory.
The key to the whole idea is wormholes—specifically, a type of wormhole called a ring wormhole. Now, wormholes are already entirely theoretical, so this discussion is going to get weird. And ...
Paul Davies, How to build a time machine, 2002, Penguin popular science, ISBN 0-14-100534-3 gives a very brief non-mathematical description of Gott's alternative; the specific setup is not intended by Gott as the best-engineered approach to moving backwards in time, rather, it is a theoretical argument for a non-wormhole means of time travel.
In the Einstein–Cartan–Sciama–Kibble theory of gravity, however, it forms a regular Einstein–Rosen bridge, or wormhole. Schwarzschild wormholes and Schwarzschild black holes are different mathematical solutions of general relativity and the Einstein–Cartan theory. Yet for observers, the exteriors of both solutions with the same mass ...
Ronald Mallett loves the concept of time travel. He has since he was a kid. At 77, the former University of Connecticut physics professor still isn’t backing down from his theory: A spinning ...
