I have some questions; I hope you don't mind:
$\bullet$ If the space between two distance galaxies is increasing, then is the volumes of space in which the galaxies find themselves also moving apart?
$\bullet$ In this case, although nothing can move (locally) faster than light in space, can space itself move faster than light? Relative to another piece of space?
$\bullet$ How would you be able to tell if the space you are in is
a) moving at a constant velocity past you
or,
b) accelerating past you?
