Why the Edge of the Universe Won't Stay Quiet

Some signals don't just travel far. They travel from the very edge of what we're allowed to see, and a few of them shouldn't be there at all. From a hum in spacetime made of dead black holes to a sky that's twice too bright and a tug that seems to come from beyond the observable universe, these are the messages from the far border of the cosmos that scientists still can't fully explain. We saved the oldest one, the wall of first light itself, for last.
