Clearly you do not; don't worry, most of
your brothers in Einstein can't comprehend
that inconsistent mumble of your divine
guru as well.
 
So, a simple (maybe even simple enough for
you) question.
An observer (Alice) is observing an object O
in the position of x. The velocity of the object
is 0, space is inflating. Does the position
change?
Yes or no.

Gibberish.

Positions have 3 coordinates.

Velocity with respect to what?

Define "space is inflating".
