In physics and fiction, a wormhole is a hypothetical topologicalfeature of spacetime that would be, fundamentally, a 'shortcut' through space and time; although they are very popular in science fiction, there is no actual evidence that they exist. For a simple visual explanation of a wormhole, consider spacetime visualized as a two-dimensional (2-D) surface (see illustration, right). Now, if we 'fold' this surface along a (non-existant) 3rd dimension, it allows us to picture a wormhole 'bridge'. (Please note, though, that this image is merely a visualization, to allow the limited human brain to grasp an essentially unimaginable structure existing in 4 or more dimensions.) A wormhole has at least two 'mouths' that are connected via a 'throat', or tube. If the wormhole is traversable, then matter can 'travel' from one mouth to the other via the throat.
I never listen about this topic but I watch a program on tv and sound fantastic, but I dont understan to much.
it will be fantastic if we 'll translete to other galaxy.
