Modern cosmology has introduced the concept of
'expanding space'. Cf. the inflation theory of
creation, and recently the dark energy 'negative
gravity' hypothesis. In these scenarios, it is
posited that the expansion can actually be faster than light.

The assertion of expansion of empty space (inflation) is designed to avoid
the implication that objects can move faster than the speed of light. It is
designed to save the SR postulate that no object can move faster than the
speed of light.

This bugs me, because from an instrumental viewpoint,
things move apart, right? All motion is relative.
Then, what is the difference between 'A and B are
separating by moving through space', and 'A and B
are separating as space expands'?

The difference is that the observed horizon of our universe appears to be
larger than the age of our universe. For this to happen, the objects must
move apart faster than the speed of light to acheive such a large horizon.
That's why the astronomers came up with the assertion that it is not the
objects in the universe are moving apart but rather it is space that is
expanding between the objects. I have a new model of the universe that will
avoid the horizon problem and at the same time explains the accelerated
expansion of the universe.
A paper entitled "Unification of Physics" is available at the following
link. It includes a new theory of gravity and it unites gravity with the
electromagnetic and nuclear forces naturally. Also, it includes a new
proposed experiment to detect physical space.
