We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after ...

Until now, we’ve only detected gravitational waves originating in binary systems, from the merger of black holes or neutron stars. But researchers from Northwestern University have potentially ...

The strength of a gravitational wave as a function of distance from the origin (horizontal axis) and a specific measure of time (vertical axis). The two panels represent results from two different ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

Speculative new research outlines a method for detecting extraterrestrial civilizations: by catching the gravitational waves produced by the collapse, or failure, of their warp drives. Sounds wild, ...

The Hubble Space Telescope has recently captured extraordinary images of a rapidly collapsing star system in the Andromeda Galaxy. This discovery offers a unique glimpse into stellar evolution and the ...

Here’s what you’ll learn when you read this story: Black holes usually form from stars that burn out and collapse in on themselves, but that cannot explain the red spark of light that could be a ...

Paleontologists recognize five big mass extinctions in the fossil record, marked by the loss of a significant number of species in a (geologically speaking) short span of time. Theories to explain ...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...
