Two clusters collided, with most of the observable objects being just past the middle point right now, 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. Adjusting equations doesn't really work in this case, there must be something physically there.
I'm not sure why this isn't mentioned first thing every time in dark matter discussions because it's literally the only thing that's pretty hard evidence imo.

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.
