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.
Superluminal communication other than possibly through wormholes is likely impossible [1] because, in a Lorentz-invariant theory, it could be used to transmit information into the past. This would complicate causality , but no theoretical arguments conclusively preclude this possibility.
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 ...
Traversable wormholes may be more than science fiction. Three new studies propose new theories for how to construct one. Human-Safe Wormholes Could Exist in the Real World, Studies Find
Negative energy appears in the speculative theory of wormholes, where it is needed to keep the wormhole open. A wormhole directly connects two locations which may be separated arbitrarily far apart in both space and time, and in principle allows near-instantaneous travel between them.
The behavior of this space and the material which approaches it are not well understood, with a complete marriage of relativity and quantum physics yet to be achieved. In the final chapter, Thorne delves into even more speculative matters relating to black hole physics, including the existence and nature of wormholes and time machines. [1]
Long before "Twilight" put Jacob on the map, werewolves have been the subject of countless movies, books and monster tales.. In fact, much like ghosts, witches and vampires, the werewolf has been ...
