Sabine Hossenfelder: "The solution of general relativity that describes the=
 expanding universe is a solution on average; it is good only on very large=
 distances. But the solutions that describe galaxies are different - and ju=
st don't expand. It's not that galaxies expand unnoticeably, they just don'=
t. The full solution, then, is both stitched together: Expanding space betw=
een non-expanding galaxies...It is only somewhere beyond the scales of gala=
xy clusters that expansion takes over." http://backreaction.blogspot.bg/201=
7/08/you-dont-expand-just-because-universe.html

So cosmologists apply the expansion solutions only to voids deprived of gal=
axies; to galaxies and galactic clusters they apply nonexpansion solutions.=
 Why do cosmologists resort to this trick? Because, if they applied expansi=
on solutions to galaxies and galactic clusters, observations would immediat=
ely disprove the expansion theory. Here is why:

If expansion is actual inside galaxies and galactic clusters, the competiti=
on between expansion and gravitational attraction would distort those cosmi=
c structures - e.g. fringes only weakly bound by gravity would succumb to e=
xpansion and fly away. And the theory, if it takes into account the intraga=
lactic expansion, will have to predict the distortions.

But no distortions are observed - there is really no expansion inside galax=
ies and galactic clusters. And cosmologists, without much publicity, have s=
imply made the theory consistent with this fact.

Since there is no expansion inside galaxies and galactic clusters, perhaps =
there is no expansion anywhere? "Expanding space between non-expanding gala=
xies" sounds awkward, doesn't it?
