bouncing:  captain sojure, he was all right, but I remember right out of atmosphere, when zero G kicked in, he’d always take out of his space suit pocket this purple ball, start throwing it around the cockpit.  he could bounce it off of ten surfaces, controls, HUD, the airlock, and have it come right back to his hand.  but we’d be trying to set pattern for orbit, start satellite deployment, and the captain would be throwing this ball around like a kid on christmas morning.  some theory in school about how in certain conditions the collisions of objects of super-dense mass, quasars, white dwarves, would not collapse or combine, but, well, bounce, like that little ball of his.  crazy captain, probably on some rubber world right now, frictionless dances with aliens.
