Wormholes, theoretical passages through space-time, have captivated scientists and science fiction enthusiasts alike for decades. With the potential to connect distant regions of the universe, ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...

The universe isn’t just growing—it’s speeding up as it does. That discovery stunned scientists, upending long-held ideas about gravity and motion in space. This rapid expansion wasn’t predicted by ...

Here’s what you’ll learn when you read this story: In May of 2019, a short-duration binary black hole (BBH) merger contained no evidence of the inspiral signal typical of these kinds of a ...

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 ...

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 ...

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 ...
