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 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.
The Ellis drainhole is the earliest-known complete mathematical model of a traversable wormhole.It is a static, spherically symmetric solution of the Einstein vacuum field equations augmented by inclusion of a scalar field minimally coupled to the geometry of space-time with coupling polarity opposite to the orthodox polarity (negative instead of positive):
“The time machine is a natural consequence of the wormhole existing,” Toby Wiseman, a professor of theoretical physics at the Imperial College London who was not a part of the study, told New ...

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 principle of self-consistency is intended to rule out such behavior. It insists that local physics is governed by the same types of physical laws as we deal with in the absence of CTCs: the laws that entail self-consistent single valuedness for the fields. In essence, the principle of self-consistency is a principle of no new physics.
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.
