Could dark matter behave similarly to regular matter? If so, could dark matter halos collapse and form structures, like a black hole? In this work we explore the Atomic Dark Matter Model and predicting structure formation in it using simple algebra. We build on the current literature by showing that for certain values of the variables that govern dark matter interactions, we won’t be able to determine if the halo will be able to collapse using methods to track the dark matter number densities and how efficiently the halo can dispose of its initial energy.
