Gravitational Waves Detected for First Time (Discovery News)
"A century after being proposed by physicist Albert Einstein, scientists have made the first detection of gravitational waves -- massive celestial objects on the move causing spacetime itself to ripple -- a historic discovery that opens up an entirely new way of studying the cosmos."

Observation of Gravitational Waves from a Binary Black Hole Merger (Physical Review Letters)
"A century after the fundamental predictions of Einstein and Schwarzschild, we report the first direct detection of gravitational waves and the first direct observation of a binary black hole system merging to form a single black hole. Our observations provide unique access to the properties of space-time in the strong-field, high-velocity regime and confirm predictions of general relativity for the nonlinear dynamics of highly disturbed black holes."

Gravitational Waves Detected 100 Years After Einstein's Prediction (Cal Tech)
"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. This confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window onto the cosmos."
