That works for linear motion but not for rotation—that requires acceleration (provided by gravity).

I forgot when the first manned spacecraft went into zero gravity and they got left behind as the Earth hurled away from them but OP reminded me about it.
Well “zero gravity” doesn’t really mean zero gravity. It’s free fall (due to gravity). If you’re in orbit, you’re moving so fast “sideways” that you perpetually “miss” the Earth and just continue falling forever.
the spacecraft doesn’t immediately lose all the celestial relative velocity just by going into space, it’s still moving extremely fast:
Think of how the moon gets dragged along with the Earth around the sun and the sun drags the Earth and moon along through the galaxy.
zero gravity
“Zero gravity” isn’t actually zero gravity. In orbit, you’re still falling, the planet is just curving away at the same rate as the fall
Wouldn’t it be inertia?

Also, if a civilization is advanced enough to create space-time bubbles, they are advanced enough to have speed matching cruise control.

Seriously, you think building a world-separating spacetime bubble that can instantly travel lightyears away is believable, but that programming it to stay on a smooth predictable course along an orbital path is NOT believable?

But would they be advanced enough to see why kids like the sweet taste of Cinnamon Toast Crunch?
