General Relativity: Four Exterior Traversable Wormhole Metric Solutions...

[Orion1]

In Einstein's theory of General Relativity, the exterior metric or exterior metric solution, is an exact solution to the Einstein field equations and Einstein-Maxwell equations that describes the metric space-time geometry in the exterior of a non-rotating or rotating neutral or charged spherically symmetric metric, and that the electric charge and angular momentum of the metric may be zero or non-zero, and the universal cosmological constant is zero. For a non-zero charged metric, the metric takes into account the Einstein-Maxwell field energy of an electromagnetic field within the space-time geometry. The space-time geometry is in Boyer-Lindquist coordinates. 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, different locations, different points in time, or both. Wormholes are based on a special solution of the Einstein field equations.
