Today, however,
然而今天
NASA physicist Friedemann Freund
美国宇航局的物理学家斐迪曼·弗罗因德
believes he may have found the answer.
相信他可能已经找到了答案
Gary, will you tell us when you make contact?
加里 闭合触点的时候请告诉我
Now, it starts.
开始了
In 2005, Freund made a peculiar discovery
2005年 弗罗因德发现了一个奇怪的现象
that if you crush a rock to almost breaking point,
如果撞击一块石头接近达到其碎裂点时
it produces a tiny electrical current.
将产生一股微小的电流
Now, we are already driving
现在 我们让这块石头
something like four nanoamps through this rock,
产生了4纳安培的电流
the pressure increases more and more,
随着压力越来越大
the current increases,
电流增加
now the pressure has already reached
现在压力已经达到了最大值
its maximum value and the current will stay up there,
电流会保持在这里
and as long as the load stays on the rock,
而且只要石头仍有负荷
the current will continue to flow,
电流将会持续存在
and that is the simulation
我们相信这个实验
for what we believe to be happening in the Earth
模拟了地震发生前
prior to an earthquake,
岩石断裂前
before they rupture.
地球所处的情况
If you can imagine
可以想象
that you have a cubic kilometre of rock being stressed or
如果一块1立方千米的岩石被加压
the currents translate into thousands, ten thousand,
电流会转化成上千上万
sometimes hundreds of thousands of amperes
甚至数十万安培
that could flow out of a cubic kilometre of rock.
流出这1立方千米的岩石
