For the first time, researchers have detected empty voids moving faster than the speed of light — and they blazed past that cosmic speed limit without breaking the laws of relativity. A recent study ...

A dark point inside a wave of light sounds like a contradiction. It is also something researchers say they have now viewed in real time, moving so quickly that, by one measure, it outran light itself.
