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]
The term “wormhole” may even be misleading, because they can be tunnels, but may also simply be punched holes that cross through higher dimensions behind the scenes.

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. [2]
ER = EPR is a conjecture in physics stating that two entangled particles (a so-called Einstein–Podolsky–Rosen or EPR pair) are connected by a wormhole (or Einstein–Rosen bridge) [1] [2] and is thought by some to be a basis for unifying general relativity and quantum mechanics into a theory of everything.
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
This possibility was first discovered by Willem Jacob van Stockum in 1937 [1] and later confirmed by Kurt Gödel in 1949, [2] who discovered a solution to the equations of general relativity (GR) allowing CTCs known as the Gödel metric; and since then other GR solutions containing CTCs have been found, such as the Tipler cylinder and ...
The wormhole metric has the proper-time form =, where = + = + (+) = + (+) [+ ()] and is the drainhole parameter that survives after the parameter of the Ellis drainhole solution is set to 0 to stop the ether flow and thereby eliminate gravity.
