Greetings, I've heard something to the effect that MOND can explain the rotation of galaxies, but the article was very fuzzy. Can someone please explain to me MOND.... 1) How is MOND different from the inverse-square law? (math please) 2) What 'problems' in science does MOND address and what solutions does it offer? 3) How serious does the scientific community take MOND and who are the main proponents of the theory? Thanks a bunch guys, I'm excitedly awaiting replies.
