Since the universe is expanding, is it possible that the space our bodies occupy, as well as the earth, etc, is also expanding? If so, it would be relativistic - to us the sizes wouldn't appear to change. A modern day human would be a few hundred feet tall directly compared to a human from a few hundred thousand years ago.

Well more often then not, the other planets are more "above" or "below" us in reference to the galactic plane. Our universe is tilted at a roughly 63 degree angle to the galactic plane, so while not perfectly "above or below" us, they are more so than next to us.

And outside our galaxy, there are certainly galaxies above and below us in reference to our galactic plane.
