Basudeva Mishra,
You have missed the point. The red shift is due to two factors: One is due to cooling, the other is due to the direction of motion. When light takes more time to reach us, it gets more cooled, and hence more red-shifted. So distant sources are always red-shifted irrespective of direction, because the blue shift due to direction is always less than the red shift due to cooling. However, for sources that are nearer, the blue shift due to direction can be greater than the red shift due to cooling. So only some that also which are not far off are blue shifted.
When we point out possible errors, we have to be sure what they are saying; for that we have to study their views carefully and arrive at the loop holes in their arguments. The main loophole I point out is that they assume that 'anything correct in mathematics is correct in physics'. A mathematical equation can be interpreted in more than one way. That is more than one physical model will obey the same mathematical equation. In such cases we have to accept the model having physical meaning, and that model should be independently verified to see that agrees with observations.
They do not know what dark matter is. They are trying to clarify it. But unfortunately, their model requires dark matter if their model is to be complete. So I am of the opinion that their direction of search is wrong. That gives us opportunity to propose alternate models. They are also trying to explain both micro and macro using a single model. But till this time they have been unable to do that. So some of them argue that we have to be satisfied with separate theories for micro and macro, though they are still trying.
I am interested in alternate models; that is why I have asked you to what level you have reached in your model? If the universe is spinning, the 'revolving speeds' of the bodies around the center of the universe will increase with distance at the equator, but at the poles the speeds will always be zero, whatever be the distance. So you have to show from the available data, that galaxies at the same distance from the center of the universe have different speeds ranging from zero to the proposed maximum.
