> however most of the mass seems have already shot way out to the edges, as if it passed right through everything. It's pretty hard to explain with anything else other than that there's something there that has mass yet can't interact with anything else that passed through everything when the collision happened.
It is my understanding that dark matter does interact gravitationally, so I am confused by this.
I should've been clearer there, "has mass" would mean that it interacts gravitationally and has inertia while moving. But that's about it, from what I understand.
