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 ...

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 ...

Science fiction is full of amazing space phenomena. Some of those phenomena have gone from theory to reality — like black holes and pulsars. But what about wormholes? These portals through space are ...

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 ...

Back in 2019, the gravitational wave observatories LIGO and Virgo detected major ripples in spacetime. While astronomers generally agree that the event, dubbed GW190521, was the result of two black ...
