This beautiful old chart, headed "Unbelievable Time Required to Cover Immense Distances of Space", displays the time it would take to get to various "nearby" celestial objects, using an unspecified propulsion system. Does anyone know what that system was, or where the chart comes from?
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
