The Deeper You Go In Space, The More Terrifying It Gets

The edge of space sits only about one hundred kilometers above your head, closer than the next city over, and the moment you crossed that thin line the air would leave your lungs and the moisture on your tongue would begin to boil. Tonight we travel outward from that pale blue shell one threshold at a time, and at every step the fear changes its shape into something the last one could never have prepared you for, from the airless silence of the Moon to the seventy-thousand-year gulf between the stars, from the graveyard of a hundred billion suns to the great voids so empty they can convince a civilization it is alone, all the way to the cold and quiet end of time itself. But what if the most frightening thing about space was never what is out there, waiting in the dark, but how completely and how calmly it fails to notice that we are here at all? This is a slow, patient walk down the ladder of cosmic scale, made for listening with your eyes closed. We move gently from the boundary of the sky to the far side of the Moon, through the near-empty reaches of the Solar System, across the interstellar dark where sunless worlds fall forever, out past the Milky Way and its silent neighbors, into the enormous emptinesses between the galaxies, and finally to the accelerating horizon that is carrying almost the entire universe permanently out of our reach. Along the way we sit with the strangest consolation the subject allows, which is that in all that indifferent immensity, we appear to be the one part of it that ever looked back and understood what it was seeing. Get cozy, dim the lights, and let this quiet descent through the terror and the wonder of deep space keep you company tonight.
