What should be the minimal radius of the so called ring-like space station to minimize the effects of rising masses moving from us and different gravities depending which way we run inside that space station?

$\begingroup$ What exactly do you mean by "effects of rising masses moving from us" ? In such a space station, "up" means towards the axis of rotation, so if the radius is small, it will be noticeable that the up vectors at 2 nearby points aren't parallel. Is that what you're asking about? $\endgroup$– PM 2RingCommented Nov 25, 2020 at 14:57

$\begingroup$ You seem to be confusing mass with force $\endgroup$– Carl WitthoftCommented Nov 25, 2020 at 15:11

$\begingroup$ the latter effect is called the Eötvös Effect. $\endgroup$– JEBCommented Nov 25, 2020 at 17:19

The effects you describe will decrease as the radius increases, but will never go away. You will have to decide what constitutes an acceptable level of inconvenience.
