That's the exact reason why RAA0G exists. Space is giant. Giant, and terrifying, and without gravity. It's a hellscape, and any sane person would stand against exploring it.
If our shapes cannot be oriented, how can we be oriented?
Only for 4D shapes, for 3D shapes they get suck in the little alcove in the middle, they can't percieve or travel along the 4th dimension so that little part is almost like a space "inside". Of course there isn't a space inside in actuality, the 3D space just gives that illusion, but for objects bound to the 3D world it is essentially the inside for all intents and purposes.
