Dark matter cont…
has greater density than visible matters.
makes it easier to form galaxies, billions of years ago.
Galaxies with regions that have slightly greater than average densities attract more matter through gravitational force.
Imply that process would have operated more efficiently, dark matter gravitational forces add to smaller gravitational forces from lesser amount of visible matter.
Even with large amount of dark matter, welcome fact:
- best theories have difficulty explaining how universe develop such enormous structure in few billion year after “Big Bang”.
Lead to 2 questions that strongly relate…
