How do they even know any of this? I thought the only way we knew about dark matter is because it “has to” exist for the structure of galaxies and clusters to act the way they are. Now these are some detailed observations.
I believe they can estimate the location based upon how the dark matter interacts with gravity and orbits.

That website is totally missing all the cool ads and has 3 images instead of 1 which is totally overboard! Who are those guys anyway?
