That’s not a very good example I don’t think. I’m no cosmologist, but my understanding is that we know pretty well that distant celestial objects are moving away from us faster than the speed of light. Special relativity doesn’t really say anything about non local objects, and the expansion of space does not violate locality. No information is being transmitted faster than the speed of light. The medium through which light is traveling is changing. It’s not some big unsolved mystery.
