What Would Deep Space Actually Do to a Generation Ship?

A speck of dust smaller than a living cell would hit a ship moving at two percent of the speed of light as a flash of fire. On a generation ship bound for Alpha Centauri, that would happen hundreds of thousands of times a second, for two centuries. So what would deep space actually do to it? Tonight we ride outward with fifteen hundred people, past the edge of the Sun's protection and across two interstellar clouds, meeting each thing the dark would do to their ship in the order it arrives. Get comfortable and let this long crossing toward Alpha Centauri keep you company tonight. Subscribe to Space After Midnight if you like falling asleep somewhere far from Earth.
