If you can get some high resolution pics of stars near the sun from the recent total eclipse (greater than one pixel per star but not so many that the number of pixels is too large relative to relativistic deflection, and comparable pix a few months away from eclipse day, you could perhaps...

Fascinating. I stand thoroughly corrected, caught in a physics cross-fire. But tell me what facts rule out non-luminous normal matter, if you would be so kind and complete. What ARE the current leading candidates?

So the peripheral stars studied by Dr Rubin were bound to the galaxy according to Newtonian physics, alright. There's just a lot more mass than is observable, including (but decreasing towards) the periphery, as one would also expect from Newtonian physics, in order for increasingly less dense...

Is it correct to say that the reason why stars at the periphery of galaxies are observed to orbit faster than can be accounted for by Newtonian physics is because they are gravitationally bound to relatively high density distributed matter also present at the periphery that must be attributed to...
