Actually, I think it has been around longer then that. According to Wikipedia the MOND theory was proposed somewhere in 1981.
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.
