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 ...

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.

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

The prospect that wormholes could one day enable time travel isn't new. In fact, the use of wormholes to transport yourself across vast distances of space and time has been used in science fiction for ...

Dubbing these “closed timelike geodesics” (CTGs), Ralph and Sajeendran explain in the paper: “Such a CTG would be ideal for studying situations in which a particle interacts with its past or future ...

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 ...

Faster-than-light travel is impossible according to our current understanding of physics. Wormholes are theoretically possible but require unstable, exotic matter to stabilize. Generation ships are a ...
