The final rung: the edge of the observable universe, 46 billion light years out in every direction, farther than light's travel time alone would allow because space itself has stretched while the light flew. Inside this sphere: about two trillion galaxies. Outside: more universe whose light has not reached us yet. From the Moon to here, the whole ladder, and you climbed it.
