I never asked for why the matter is at large radii.
I just realized that maybe the disk is considered part of the Halo, and therefore any dark matter in the disk is also in the halo. So halo objects may just as well be in the disk, right?
Hi, I was just wondering, why are we only looking for massive compact HALO objects?
Can there not be such objects in the Galaxys disk, if so why? Or have simply already detected all of them, if so how?
