Could it be that there is no dark matter out there at all...? Don't get me wrong, I am excited to think that there is the possibility of Dark Matter, but what I understand is that the gravitational pull of stars on the outer rim of our known galaxy are moving faster than what they should be considering the "Rotation Curve". The furthest star on the edge of our known galaxy is ULAS J0015+01 which is 900,000 light years from Earth. Could it be a simple answer that our galaxy had a stronger gravitational pull 900,000 years ago? That the Stars were moving an increased speed 900,000 years ago...? And what we are looking at is just an eco of what the universe speed/gravitational pull once was...?
