I was tempted to leave out the Wiki link in my post as it has some dated information, both for and against MOND, but it's easy enough to find so I included it; Wiki also shows variant MOND theories and related links. Moreover, my post has links to current MOND data, which better explains criticisms and concerns. Keep in mind, MOND variants are still developing, mostly outside of the USA (where I'm from), and without significant funding; unlike Dark Matter. Lastly, this isn't a crackpot theory, can be falsified (older models have been), makes predictions (has already made and proven many up to this point). All of this and more is addressed by Prof Dr Kroupa and his colleagues in the field, as well as in the data linked from my original post. I hope this helps one and all.
