The Ellis drainhole is the earliest-known complete mathematical model of a traversable wormhole.It is a static, spherically symmetric solution of the Einstein vacuum field equations augmented by inclusion of a scalar field minimally coupled to the geometry of space-time with coupling polarity opposite to the orthodox polarity (negative instead of positive):
A wormhole is a hypothetical structure which connects disparate points in spacetime. It may be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are based on a special solution of the Einstein field equations. [1]
Real or not, wormholes can still give scientists crucial insight into our universe.
Some years later M. S. Morris and K. S. Thorne manufactured a duplicate of the Ellis wormhole to use as a tool for teaching general relativity, [3] asserting that existence of such a wormhole required the presence of 'negative energy', a viewpoint Ellis had considered and explicitly refused to accept, on the grounds that arguments for it were ...
According to the heavy-duty number-crunching, the ring wormholes could generate something called a “closed timelike curve” if one “mouth” of the wormhole near a bunch of mass and the other ...
Visual representation of a Schwarzschild wormhole. Wormholes have never been observed, but they are predicted to exist through mathematical models and scientific theory. Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena.
The existence of a traversable nonorientable wormhole would seem to allow the conversion of matter to antimatter, and vice versa. A universe that includes one of these "non-orientable" connections does not allow a global definition of whether a particle is "really" matter or antimatter, and this sort of universe, with no global definition of ...
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 ...
