LOS ANGELES - A team of Russian astrophysicists have speculated that supermassive black holes that are known to rip through the fabric of space-time may actually be the entrances of wormholes ...

Wormholes are a controversial topic in physics, to say the least. Not only is the idea of traveling through these theoretical passageways between two disparate regions of spacetime debatable, but ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of "Ask a Spaceman" and "Space Radio," and author of "How to Die in Space." Sutter contributed this article to ...

While the simplest theoretical wormholes immediately collapse and disappear before anything can get through, Thorne wondered whether it might be possible for an “infinitely advanced” sci-fi ...

Sci-fi writers have long leaned on the wormhole as an important plot device. It’s a quick way to get characters from Point A to Point B across vast distances in spacetime in a matter of seconds. But ...
