I am asking this question only because I want to figure out does space move in this case similarly to a fluid like water or oil are or even more better as speeds o planets around a star.. or this phenomena has a different formula describing a complex effect caused by the gravity as a force deriving from S-T curvature? Thanks in advance for an 'easy to understand' answer....

$\begingroup$ The equations for the frame dragging angular and local velocity can be found on Wikipedia where you can also find an animation of frame dragged ZAMOs. If you had a fluid it would depend on it's viscocity, so maybe you are asking about the viscocity of spacetime, but we do already have some postings on that. $\endgroup$– YukterezCommented Oct 15, 2023 at 19:17

$\begingroup$ @Yukterez So if a body approaching a RBH in direction of frame rotation enters in the fast, inner parts of the FD region and then manages to leave that region it would not gain any extra velocity deriving from the Rot.BH energy? In Simpler words there is no way to extract the RBH energy? $\endgroup$– jbradvi9Commented Oct 15, 2023 at 23:14

$\begingroup$ You can extract with the Penrose Process, see MTW, Fig. 33.2 $\endgroup$– YukterezCommented Oct 16, 2023 at 1:09
