Tiniest gravitational field ever created may solve a mystery Einstein couldn't. Researchers are closer than ever to a grand unifying theory. by Sarah Wells ...

A new method to analyze gravitational-wave data could transform how we study some of the universe's most extreme events—black ...

Effective Field Theory (EFT): A framework that simplifies complex interactions by integrating out high-energy phenomena, allowing for accurate descriptions of long-range forces.

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research ...
