What does the high prevalence of dark dark matter halos suggest about galaxy formation efficiency?
Answer
The process of drawing in and retaining baryonic gas is surprisingly difficult.
If many massive gravitational structures (halos) fail to create stars, it implies that successfully accumulating and holding onto the necessary gas requires extremely fine-tuned initial conditions beyond just having a gravitational pull.
