In theory, travel through this could allow much faster passage than travel in the familiar external spacetime that connects them. This is an example of a general class of spacetime structures with two ...

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to some equations.

In development for several years, Jonathan Nolan's original sci-fi tale Interstellar, which deals with time travel and wormholes and once looked close to being a Steven Spielberg movie, has now ...

And let’s just beat this dead horse one more time—even if wormholes exist, as well as the means to make them traversable, to go back in time seems to require anchoring one end in a region of ...
