Gravitational waves are created whenever massive objects undergo any kind of acceleration. In the case of those first detections, the signal was produced by pairs of black holes within our galaxy ...

The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years, he published the general theory of relativity. In it, he suggested that gravity is not a ...

LIGO is a facility that detects gravitational waves -- transient disturbances in the fabric of spacetime itself, generated by the acceleration of massive bodies. It was the first to detect such waves ...
