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).
In the Einstein–Cartan–Sciama–Kibble theory of gravity, however, it forms a regular Einstein–Rosen bridge, or wormhole. Schwarzschild wormholes and Schwarzschild black holes are different mathematical solutions of general relativity and the Einstein–Cartan theory. Yet for observers, the exteriors of both solutions with the same mass ...
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.

The behavior of this space and the material which approaches it are not well understood, with a complete marriage of relativity and quantum physics yet to be achieved. In the final chapter, Thorne delves into even more speculative matters relating to black hole physics, including the existence and nature of wormholes and time machines. [1]
It involves a highly theoretical object called a “ring wormhole,” which is a type of wormhole that connects two regions of space, like a portal. Ring wormholes had previously been theorized to ...
Additionally, every space location has a future time, implying that an object may stay at any location in space indefinitely. Any single point on such a diagram is known as an event . Separate events are considered to be timewise separated if they differ along the time axis, or spacewise separated if they differ along the space axis.
In general relativity, a Roman ring (proposed by Matt Visser in 1997 [1] and named after the Roman arch, a concept proposed by Mike Morris and Kip Thorne in 1988 and named after physicist Tom Roman) [2] is a configuration of wormholes where no subset of wormholes is near to chronology violation, though the combined system can be arbitrarily close to chronology violation.
Spacetime topology is the topological structure of spacetime, a topic studied primarily in general relativity.This physical theory models gravitation as the curvature of a four dimensional Lorentzian manifold (a spacetime) and the concepts of topology thus become important in analysing local as well as global aspects of spacetime.
