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>

I am envious that others have abilities I do not. Ignorance is my
problem until I meet up with my poor ability to memorize by rote.
However, I am also envious of abilities to create music and write it
down in musical notations, in an ability to think in mathematics and
use the language of math to share those thoughts with others or the
ability to pick up pallet and brush and share some inner fantasies
with those that want to pay attention.

As Shakespeare said, "Wishing me like him, him with friends possessed,
desiring this man's art and that man's scope..." Some people envy
power or wealth, I envy talents.

However, back to the subject, I understand we are evolving theories of
the makeup of our universe and life via mathematics. It has become
the language of the current priesthood. So long as it remains known
only to a priesthood, us ordinary beings must rely on renegades
willing to interpret for us.

In the end, what I think matters not to anyone but me, for me my
satisfaction is everything. A complementary conundrum.
