Morph Ball & Subspace

I have a theory about how Samus’s Morph Ball works. First of all, I don’t think she actually rolls around inside a metal sphere – that would be crazy. I think the Morph Ball exists completely separately from Samus’s armor and is stored in some parallel plane of existence. When you activate it, Samus switches places with it and observes it from “subspace”, or whatever. So in the Prime games, when you are in Morph Ball mode, the game is still in first-person view; you’re seeing what Samus sees as she steers the ball around. And of course, because the Morph Ball shares whatever shielding protects Samus’s normal armor, damage to one damages the other.
Now about how she steers while doing repeated somersault jumps… I don’t have an answer for that.
