And it would depend then on the dimensionality of... well, of what? of "outer space"? is this "outer space" different from our "inner space"? Obviousely, it HAS to be different - othervise gravitons and photons would propagate in it exactly the same way they propagate in "inner" 3-D space, thus making gravity and electric field weakier in our "inner space". So, instead of inverse square fields would drop faster with the distance - depending on the total dimensionality of both "spaces".

So, we have no space similar to "inner space" beyond it.

And if the "outer space" is DIFFERENT than "inner space", well - can we call it space then? And if NOTHING we know can propagate in it (nor gravity, nor photons nor matter) - what evedence do we have then that there is ANYTHING "space-like" out there, beyond of our 3-D space at all?
