Glen I find all of that most interesting but until "they" establish how "pull" works it seems that all the speculation upon gravity being a force that works via attraction will continue to present greater problems... Now I dont know if I have ever suggested this before but it may be that there is no force that we describe as "pull" and therefore a lot of the current thinking has been based upon a faulse premise... It would seem to me that if "push" is the way gravity works we firstly eliminate the need for dark matter... it is interesting that the more dark matter one adds in an effort to make the current sums work one finds one must just keep adding more and more and never will a point be reached where there is enough to explain our observations so as to fit them within a context of "pull"...
I think the use of a comparrison between a man in a lift and gravity is reasonable however the assumption there is a force we call attraction is not science and I have yet to see any experiment that establishes attraction as a force... that does not mean there is none but that I do not know of it... I simply say what we assume is that one body attracts another because we see them move toward each other and I find when one examines any action where we assume it works via pull I find that at the point of contact the action is one of pushing... Tailway and I argue about his gate ..that he pulls it shut and certainly such seems reasonable however at the point of contact we can only exert a force that is a push and that occurs even if we pull the gate in our direction..the point of contact is always push..and so although a simple observation and hardley appropriate to apply to the greater universe in the way the man in the lift has sucessfully applied to formulate the Theory of General Relativity my example is merely to say that when examined close up things can be the opposite to what we assume.
I think the MOND thing is still beating the same horse but with a different stick and that horse is never going anywheres because it is a dead horse.
