As to where I understand many critics have pointed out that MOND cannot explain the observed masses of clusters of galaxys without invoking dark matter, in the form of almost massless particles (neutrinos).
I was reading something on another (new) modified gravity theory called the Scalar Tensor Vector Gravity (STVG). According to researchers this theory can account for both galaxies and galaxy clusters.
I don't quite remember where I read about this at. I found something about it on Wikipedia, but there is not much info there either. If I find more on it I will post the link later.

Diana,
Unlike in the past. MOND is being is being taken very seriously now.
So is the proposition that 'black holes' are indeed, dark stars, so dense
that matter falling into them becomes changed into a quantum state
we yet not understand.
The proposition of my thread was, and is, did Newton get it so slightly
wrong?. The balance between the earth and the Sun should be null
according to Newton, and Albert, but MOND theory predicts a small variation.
Diana, Nasa Pioneer 10 and 11 seem to be decelerating more than predicted, but the rate of deceleration would hold true if Bekenstein's
theory holds true.
