This kind of article will drive me wanting to dig further. I've always been looking out at the night sky and think is that something that suck away the light? Light traveling at certain speed, but the distance slowing them down or stopping them from reaching us. Which means, are we looking at a dead star that no longer exist? May be it was blown up to dust for God knows quintillion light years ago? We're only looking at the history of a light reflecting from our telescope?
These things always make me sit there for hours thinking.... Hmmm
