Reversing the technology to use the lens as a transmitter instead of a receiver would enable aliens to beam massively powerful signals across the galaxy, said Dr Drake.

德雷克博士说，把这项技术反过来，利用透镜作发射器而不是接收器，能使外星人发送大量强劲信号传遍银河系。

By contrast, Voyager 1, the most distant functioning space probe, is using an extremely weak transmitter to beam radio messages back to earth across 10 billion miles of space.

与此形成鲜明对比的是，最遥远的旅行者1号太空飞船在飞出100多亿公里之外，还能利用极其微弱的发射器将无线电信号传回地球。
