Special Feature: Gravitational Waves Detected
Northwestern scientist Vicky Kalogera absolutely could not believe it. The data revealed that gravitational waves -- ripples in the fabric of spacetime first predicted by Albert Einstein in 1916 -- had been detected for the first time by an international scientific team to which she belongs. Even Einstein didn’t think such a discovery would ever happen.
For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe.

One hundred years after Einstein predicted the existence of gravitational waves, scientists have finally detected them: a burst of ripples in spacetime born of the catastrophic merger of two black holes. A timeline of milestones over the last century.
