Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean ...

According to Einstein’s theory of general relativity, gravitational waves warp spacetime. In the process, they could imprint permanent changes, or “gravitational memory,” on their surroundings.

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 ...

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 ...

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 ...

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, ...

Two separate research teams have observed a previously unseen microlensing event, confirming the existence of a particular ...
