You mentioned the normal or bell or gaussian distribution,
and one thing about probability theory and statistics is
that people only know Central Limit Theorem with regards
to the asymptotics and infinite limits and continuum limits
of the theory, yet, there may as well be other law(s) of
large numbers and variously Uniform and Polar Limit Theorems,
as with regards to that it's not necessarily so at all that
statistics the theory is correct enough when in the asymptotics,
or the infinite limit or continuum limit, that it's not a thing.


Galaxies as independent rotating frames, basically has
the universe wheels about them not them about their center,
thusly, the otherwise spiral-looking distribution usually,
is from initial conditions, not so much evolution. That
is to say, equipping the theory with that naturally enough
at galaxy scales, that once distant others, it's as of
a sort of Steady-State, not so much expanding.

Of course James Webb Space Telescope has roundly paint-canned
inflationary cosmology, and since 2MASS found about 51/49 red-shift,
not 99/1.


Lots of analysts only know Central Limit Theorem, which is great,
yet it simply doesn't always apply, and the mathematics with
more than one law of large numbers, law(s) of large numbers,
is often enough these days yet called "non-standard analysis",
though you can ignore "hyper-reals" as useless, yet there
really is "non-standard probability theory" where these kinds
of things are more present in the academic literature.


It's all subject the completeness of mathematics, of course.

"Mathematics _owes_ physics more and better mathematics of infinity."
