How Far Humans Can Ever Go — The Hard Ceiling on Our Reach

The distant cosmic horizon quietly sets a gentle limit on how far human exploration can ever reach into space. Designed to help you fall asleep across just over two hours, the steady narration contains no sudden noises to wake you. We trace the fossil light of the beginning, the runaway acceleration of space, and the rivers of the cosmic web. You can drift off peacefully while contemplating the quiet wealth of our accessible domain.
