Hello everyone in PF land, I'm a long time reader, first time poster. My friend and I were conducting a thought experiment involving a spacecraft with a rotating section to produce artificial gravity. The rotating section would be accessed by a tube section that does not rotate. (I've attached an illustration showing our craft.) In our illustration, astronauts B and C would experience 1G due to the rotation of the craft, and astronaut A would experience zeroG because the access tube is not rotating. Is our assumption correct so far? Now, we are assuming that as astronaut A travels through the access tube to the rotating section, he will continue to float in a zeroG "zone" in the center of the rotating structure. If this not the case, what would happen to astronaut A as he entered the rotating section? Would he be forced to the inner wall where astronauts B and C are standing? Could he float in between B and C?
