    The animations on this channel are really great!

    How the hell there is no mass at a center of galaxy when there is black hole weighing billions Sun's masses and not to mention all the stars that it attracts.

      The very center of the galaxy would be a point, but very quickly the galaxy mass increases as you move away from this point and include various objects in the galaxy (including black holes)

    What if this observed "fast" matter just flew in from intergalactic space and it's being slowly pulled in towards centre?
    It's moving faster than matter we see clumped up in galactic spiral. It clumps up - shines up - and speed drops.
    As if there is just cold, inert, low density matter zooming around that's hard to detect until it starts to interact with gravity of a galaxy.
    So key points are that this matter is faster than what we see in a galaxy and gravity is just like give that here u coming in... heh
    Tell me how wrong I am. please

    Can it be that it's just planets? They are very hard to detect. What if there are just a lot of planets in some galaxies and they add to the gravity and mass of it all?

    You know the centres are moving faster than they appear right, gravity is fastest/strongest at the centre of the galaxy and the further/weaker gravity it. Mainstream are always asking the wrong questions, it's not why are the outside stars moving slower than expected, it should be why are the centre stars not moving faster and the answer is: they are moving faster but gravity gives the perception that its slower.
