I haven't yet named the culture or species that invented this technology, but this is what their ships look like. Their propulsion system (and energy production) is very unusual. Rather than storing fuel in a tank, the entire mass of the ship is available for use. High-speed radiation is ejected out the back while the rest of the ship and its occupants decrease in mass/inertia (and volume). Those returning from long trips to recharge at port are often very tiny.
