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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Solutions to Einstein's famous equations back in the 20th century describe 'wormholes,' or tunnels through space-time. Mark ...

In some ways, a wormhole might look like a black hole. And the wormhole would look like a sphere, not a hole. Einstein's theory of general relativity allows for the possibility of wormholes, but there ...

Wormholes sit at the edge of science and storytelling, promising shortcuts across the cosmos and even pathways through time. Even if these tunnels in spacetime never turn up in a telescope, the effort ...

Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how gravity scales up to the full size of our universe. Specifically, ...

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 ...
