We know that ΩDM=0.26
and ΩBM=0.46 which this leads us this result ΩDM=5ΩBM
So In universe If there's m baryonic matter there will be 5 times more dark matter (5m).This is true in larger universe distances
Milky way galaxy mass is 9x1010 solar masses but dark matter value is nearly 20 times bigger then that (average of 6x1011 and 3x1012) so here ΩDM≅20ΩBM
So universe contains 5ΩBM
and our galaxy contains ≅20ΩBM.
Is that mean some places there's no DM nearby the galaxy or not nearby galaxy places ?
