Wormholes help resolve black hole information paradox

A RIKEN physicist and two colleagues have found that a wormhole—a bridge connecting distant regions of the Universe—helps to shed light on the mystery of what happens to information about matter consumed by black holes.

Microscopic wormholes possible in theory

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 ...

Video: Can wormholes act like time machines?

Time travel into the past is a tricky thing. We know of no single law of physics that absolutely forbids it, and yet we can't find a way to do it, and if we could do it, the possibility opens up all sorts of uncomfortable ...

How to spot a wormhole (if they exist)

A new study outlines a method for detecting a speculative phenomenon that has long captured the imagination of sci-fi fans: wormholes, which form a passage between two separate regions of spacetime.

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.

Scientists dismiss the idea of travel through wormholes

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.
