These were the first bobbleheads that I ever bought and installed, and they immediately confirmed what I'd suspected all along (and wanted to believe, for my own personal immersion): No matter what some know-it-alls choose to cite from Ye Olde Game Lore (never the model of consistency, anyway), you ARE subject to G-forces/inertia in your cockpit in both Supercruise and normal space (and transitions between). Therefore, there MUST BE artificial gravity -- or at least G-force dampening -- otherwise you'd be blacking out or smashed to paste from some of the maneuvers your ship does.
Case closed by the bobbing pumpkin!* ;-)
