What occurs when the universe plays a cosmic curveball, breaking down long-standing assumptions about how black holes form?

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

But it may succeed, too, and if it does, it will be the ultimate gravitational wave signal: one that's inherently quantum in origin, and one that proves that gravity is a quantum theory after all.

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 ...

That’s the origin of gravitational waves: disturbances in the gravitational field, rippling through spacetime at the speed of light, just like the ripples we get from throwing a pebble into a pond.

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

Gravitational-Wave Signatures When Albert Einstein published his general theory of relativity in 1915, he recognized that it implied the existence of an exciting new physical phenomenon.
