I hope this is the right place for this question. How would spinning a ship in space create artificial gravity? I've long wondered if it actually would, or if you'd just have people floating in a spinning ship. I did a minimum of searching and found that there have been actual proposals involving the principle, so I guess in theory it would work. I just can't wrap my head around why, lacking some physical connection to an object, making it spin would create artificial gravity. The image that comes to mind is spinning an object, say a rock, in circles on a string, then placing something inside the orbit of the rock unattached to the string. Would the object "gravitate" toward the rock, and if so why?
