What most people who grew up after Contact fail to realize is that Pre-Contact spaceships generated gravity by spinning small sections of the outer hull around the central spindle frame. Most of the ship was in zero gee unless they were undergoing acceleration. The crew strapped into their stations for high gee operations surpassing a quarter of Earth standard gravity, and could go for months without experiencing anything above one half gee. Pre-Contact interstellar travel was truly a different world than the one we experience now.
