Remember, too, that the reason we hear that the Cosmos

Over the years, i've asked the following question here on this NG and
others :

If the universe is undergoing "ever-accelerating expansion" NOW, in
present time, why is there no evidence of it `locally` between
galactic groups not gravitatonally bound? By 'locally', i mean out to
a distance of a billion LY or so.
Certainly there's no argument with accelerating
expansion in the deep past. But what is the argument FOR it to be
occuring now, locally, even though there is no evidence of it? Why is
excessive redshift not being observed locally?

A few milquetoast answers were forthcoming, to the effect that
(paraphrasing) : "the effect is too small to be observed in the local
cosmos because the local cosmos itself is what's accelerating away
from the deep-past cosmos." This makes no sense, and sounds like a
strawman argument for the newly-in-vogue "ever-accelerating expansion"
idea that had suddenly become dogma in the mid-1990s.
