it's like an inverse gas bubble underwater, or a liquid blob in gas in microgravity, but without phase border.

see, it's not that easy to explain or visualise.

Yeah I watched this video recently about slingshotting I can see how it works but yeah https://youtu.be/-CqBP-CtM0c?si=BdCiZwWgpAp07mgs&t=15

It's not like there is a "down" it's just you're looking at it from a top view?

There is no down, yes. There is no looking at it from a top view either, since there is no bottom. 3d models like this video are helpful, but one must keep in mind that they are but a slice.
