I learned that dark matter distrubition is homogeneius and isotrophic in cosmic scales.
I searched some galaxies dark matter distrubition.And I am actually suprised.
Why cause every galaxy has a different ratio of dark matter baryonic matter distrubition.
In cosmic scales baryonic matter/dark matter=1/5 but in galaxies its varies.
Whats the reason for that ? Why every galaxy didnt contein five times bigger dark matter.
My second question is we know that from Planck results baryonic matter density is 0.0456 and dark matter density 0.26.
It means we have a galaxy and the mass of the galaxy is will be 6m.Cause m from baryonic mass 5m from dark matter=6m.
I know that both questions are relavent each other.
Thank you
