You have not got the neurological apparatus to visualize a four
dimensional manifold. None of us do. Even visualizing a twisted three
dimensional manifold is beyond most of us. We can do a pretty good job
with two dimensionsional surfaces, though.

Is space rigid enough that it creates a "bow wave and wake?" If so how
far away from the local passage does the wave go? Does it extend into
space indefinitely setting up interference patterns as the curve
passes other curves?

Or, is space compressible like jello? Is the curve only local due to
space viscousness?

It is spacetime that is curved. The presences of matter with ponderable
mass curves spacetime. Google <ricci tensor riemann tensor Einstein
field equations>
