an alternate explination to the hubble constant is that the galaxy has a lense comprised of a change in density inside and outside the galactic bubble
if an expansive force was applied to the inside of the galactic bubble it would change the lens focal point and acount for a "perceived" expansion of
the universe due to the altered optical thickness of the lens.
in effect the outter edge of this galaxy lens changes curvature and images are lensed differently providing a moving image for us to interperate as
if the lens thickness was to decrease "deflation" the objects would apper to get closer together.
i still think expansion is occouring but the amount of observable expansion is increased by the expansion of this lens/bubble surrounding our
current expansion models do not take into account an optical expansion of distence

Ya know, as a professional videographer who has noted the sometimes incredible lensing effects of our atmosphere, I have to say, especially in light
of your caveat as relates to speed perception rather than a negation of expansion, that you've proffered an intriguing and plausible postulation.
