We’ve all heard of black holes and even white holes but what about gray holes? In this video, we explore one of theoretical physics’ strangest and least understood ideas: cosmic objects that sit ...

Researchers have built a small but powerful detector to find gravitational waves in a hidden frequency range. The discovery ...

On human timescales, the universe may as well be eternal. It’ll be here long after our species and our planet are gone, but ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

A new paper presents a method for distinguishing between different sources of nanohertz gravitational waves. Pulsars may be revealing faint ripples in the fabric of the universe, ultra–low-frequency ...

A provocative new theory suggests that the Universe may not have begun with a traditional Big Bang, but rather as a “Big Bounce” — the explosive rebound of matter collapsing into a black hole. Led by ...

But the Windy City’s “rat hole” may not be what it seems. New research into the identity of the creature that caused a sidewalk imprint when it fell into freshly poured cement suggests the culprit is ...

A frustrated family man's simple customer-service complaint turns into an elusive, ever-deepening conspiracy in the uncanny ...

Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...
