Why a Generation Ship Traveling at Light Speed Still Wouldn't Be Fast Enough

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/3enq56n... Light is the fastest thing there is, and nothing will ever move quicker. So tonight we give a generation ship the one gift physics forbids — the ability to travel at the full speed of light — and aim it outward, past the stars and our galaxy toward the deep sky. How much of the universe could the fastest ship imaginable reach? This is a long, slow ride from your window to the edge of everything we could touch, to the strange line where even light begins to lose. Get comfortable and let this long journey to the edge of the reachable universe carry you off to sleep. Subscribe to Sleep in Orbit if you like falling asleep somewhere very far from Earth.
