- A gravitational-wave detector exploits the physical effects of a gravitational wave on bodies to detect the waves. A gravitational wave detector may, for example, monitor the separation between two freely falling bodies; as a gravitational wave passes, the two bodies will experience a tidal acceleration relative to each other.

- Physicists have announced the discovery of gravitational waves, ripples in spacetime first anticipated by Albert Einstein a century ago. “We have detected gravitational waves. We did it,” said David Reitze, executive director of the Laser Interferometer Gravitational-Wave Observatory (Ligo), at a press conference in Washington.

用法说明
[编辑]gravity wave 有时被用作 gravitational wave 的同义词，反之亦然。然而，前者通常指两种流体在重力作用下相遇时形成的波，例如海面上受风吹拂形成的波浪，而不推荐使用该词描述天体物理现象。[1]
