Without assistance, the deepest anyone has gone and lived to talk about it afterward was an Italian named Umberto Pelizzari, who in 1992 dove to a depth of 236 feet, lingered for a nanosecond, and then shot back to the surface.

在没有忙的情况下，你能达到并事后能活着来谈论这次经历的最深深度是72米——这项业绩是由一名叫翁贝托·佩利扎里的意大利人完成的。他于1992年潜到那深度，逗留了1毫微秒，然后迅速返。

So we're doing is taking a huge amount of energy and compressing it down, just in 10 nanoseconds.

所以我们要做的就是把大量的能量压缩下来，只需要10毫微秒。
