But even with our increasingly powerful atom smashers, no sign of dark matter has yet been spotted.

但是即便用上越来越强大的高能核子加速器，目前依然没有发现任何暗物质存在的迹象。

So why should I care? And moreover, how can something as mundane as this super-simple atom emitting and absorbing light teach me anything about dark matter?!

那么，我干嘛要关心呢？此外，氢原子吸收与辐射光线这些超级简单的玩意能告诉我关于暗物质的什么信息呢？

Researchers at Griffith University have managed to snap the first image of a single atom's shadow and, while the dark spot may be physically small, the implications for the field of quantum computing are huge.
