God is mad

I guess

if there is dark matter - for a galaxy there is probably 10 times more
mass of dark matter compared normal mass

people say - dark matter is spread around a galaxy like a round ball
and the radius of the round ball could be 10 times radius of stars from
center of galaxy - 10 times more far than any stars from center of
galaxy

with clusters - galaxies orbit center of mass of galaxies - big
clusters have a lot of gas between galaxies - gas has a lot more mass
than galaxies

there are tidal forces between galaxies - gas between galaxies can
create big tidal forces for a galaxy

if there is dark matter and if dark matter is spread around a galaxy -
tidal forces
from galaxies and gas associated with a cluster of galaxies - would
influence dark matter around a galaxy - orbits of dark matter would
change - normal orbit of dark matter would be associated with a circle
- if orbits of dark matter were associated with an ellipse - dark
matter would fly around center of galaxy - people say dark matter is
not around center of galaxy -
tidal forces would make orbits of dark matter like an ellipse and some
dark matter may fly around center of galaxy

if dark matter was spread around a galaxy like a round ball - dark
matter would tend not to influence shape of orbits associated with
stars and speed of stars around center of mass of galaxy

if dark matter was not spread around a galaxy like a round ball -
because there is an extreme amount of dark matter - if there is dark
matter - to an extreme orbits of stars would change - shape of orbit
and speed of stars - people could probably see this - I do not think
this is happening

tidal forces of galaxies and gas could influence dark matter around a
galaxy - it could be true if there was a small change of dark matter
around a galaxy - orbits of stars would have an extreme change
