Travel through wormholes is possible, but slow
A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible.

Wormholes play a key role in many science fiction films—often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical. An international team led ...

A group of researchers at Sofia University has found evidence that suggests the reason that a wormhole has never been observed is that they appear almost identical to black holes.
(Phys.org) —Zilong Li and Cosimo Bambi with Fudan University in Shanghai have come up with a very novel idea—those black holes that are believed to exist at the center of a lot of galaxies, may instead by wormholes. They've ...
(PhysOrg.com) -- Wormholes are one of the stranger objects that arise in general relativity. Although no experimental evidence for wormholes exists, scientists predict that they would appear to serve as shortcuts between ...
J.K. Rowling may not have realized just how close Harry Potter's invisibility cloak was to becoming a reality when she introduced it in the first book of her best-selling fictional series in 1998. Scientists, however, have ...

(Phys.org)—A trio of physicists with the Autonomous University of Barcelona has built what they claim is the first artificial magnetic wormhole. In their paper published in the journal Scientific Reports, Jordi Prat-Camps, ...
A RUDN employee and Brazilian colleagues have called into question the concept of using stable wormholes as portals to different points of space-time. The results of the studies were published in Physical Review D.
