There are gravitational wave detectors spread across the world.

全球各地都有引力波探测器。

I'm in a building that contains a 1 to 100 scale of LIGO, the gravitational wave detector.

我现在所处的建筑，有一个百分之一尺寸的Ligo引力波探测器。

But scratch this surface-or more appropriately, wave a metal detector over it-and a very different England emerges, a land of violence and panic, not at all secure behind its defending sea, but terrifyingly vulnerable to invasion.

但如果刨开表面，更准确地说，如果拿着金属探测器在地面挥动一番，一个迥异的英格兰就会浮现。
