Hello,
What I understood from multiple answers on different threads is that the effect of the time dilation is too small to explain the galaxy rotation curve. I was advised to do some calculations in order to see it myself. And this is what I would like to do but I need some help.
- What is the best simple equation which represents the mass distribution as a function of R, so I can calculate the orbital velocity.
- What is the mass that I need to consider in order to calculate the time dilation for any star in the galaxy? It can't be only the mass of the central black hole but all the mass contained in the volume defined by R (distance between the star and the center of the galaxy); is it right?
