Yes.

Are you saying that galaxies etc. moving away ftl are not moving relative
to spacetime because spacetime is expanding at the same scale factor? Is
the universe, as it expands, creating vast new amounts of spacetime or just
stretching existing spacetime thinner and thinner? Are there any theories
This question is something I've wondered about, and it still seems *odd*,
but maybe this is the best answer?
As the universe expands, why don't galaxies get stretched out?
*There is enough matter in a galaxy that the matter within the galaxy is
not affected by the expansion of the universe.
Thanks Brent. You say the space is growing faster than light in a sense but
not relative to spacetime. How can space not be relative to spacetime?
