a wormhole towards a new dimension

From Wikipedia, the free encyclopedia

a wormhole is a hypothetical topological feature of spacetime that is fundamentally a 'shortcut' through space and time. Spacetime can be viewed as a 2D surface and when 'folded' over, a wormhole bridge can be formed.
A wormhole has at least two mouths which are connected to a single throat or tube.
If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing through the throat.
While there is no observational evidence for wormholes, spacetimes-containing wormholes are known to be valid solutions in general relativity.
The term wormhole was coined by the American theoretical physicist John Wheeler in 1957.
However, the idea of wormholes had already been theorized in 1921 by the German mathematician Hermann Weyl in connection with his analysis of mass in terms of electromagnetic field energy.
This analysis forces one to consider situations...where there is a net flux of lines of force through what topologists would call a handle of the multiply-connected space and what physicists might perhaps be excused for more vividly terming a ‘wormhole’.
