英语释义

1. a disturbance in space-time in the form of a wave that propagates the gravitational field
Gravitational waves are a natural offshoot of the rubber-sheet construction of general relativity. Just as a massive object sitting on the fabric of spacetime creates a dimple, so moving or changing objects, under certain conditions, create wrinkles in the fabric. Those wrinkles, tiny distortions in spacetime, zoom away at the speed of light. Because these gravitational waves carry energy, anything emitting them will lose a tiny bit of its speed.

• in fact they must release energy in that way in order to degrade their orbits and get close enough to merge. those gravitational waves could act sort of like a jet engine, explained jonker.

  jonker解释道，「事实上他们必须通过这种方式来释放能量，降低轨道，彼此靠近并最终融合，这些重力波能产生类似喷气发动机的效果。」

• it would be ironic if an instrument built to detect something as vast as astrophysical sources of gravitational waves inadvertently detected the minuscule graininess of space-time.

  一台原本用来探测引力波的天体物理来源这类庞然大物的设备却在漫不经心间发现了小到不能再小的时空微粒，这很具讽刺意味。

• if we are right then not only will gravitational waves be found so that general relativity passes a key test but astronomers will soon have a completely new way to study the universe.

  如果我们的研究是正确的，那么不仅引力波的存在可以得到证实，这将意味着广义相对论再次通过了严格的试验验证，它还将为天文学家们探索宇宙奥秘提供一条全新的途径。
