For decades, wormholes have been hypothesized as mysterious tunnels that might let us cross ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

A new mathematical model of a wormhole suggests that two black holes can be “cut and pasted.” Cut and paste is an official concept in math, referring to two surfaces that may be transposable. In this ...

Wormholes sit at the edge of science and storytelling, promising shortcuts across the cosmos and even pathways through time.

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...

Now, decades later, a new species of traversable wormhole has emerged, free of exotic material and full of potential for helping physicists resolve a baffling paradox about black holes. This paradox ...

Black holes don’t just bend space and time. They also expose where our understanding of reality begins to break.  In this ...

Back in the prehistoric days of theoretical astrophysics (1985), in a mystical and exotic corner of planet Earth (Fresno, California), a man sat in the back of a car and tried to break the spacetime ...

Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. But, if they wanted to get there ...
