Philip M Yes, I believe 4.17MB will not be a problem - please send. My interest is sparked because I thought there were one or three points made which rang alarm bells. I've only quickly read the articles as I seem to always be short of time lately but I think there are valid criticisms to be made. It reads, as is common where the writer is also the arbitrater - self indulgent. Concerning gravity - I'll have to get back to you on that. There are a number of areas where I definately do not have the competance to comment, and this may be true here. I especially am uncomfortable in the area of 'frames of reference'. This seems to me to be an arena of fairly rarified theoretical aspects which can be largely ignored if your field of interest is simply the Newtonian aspects of a solar system, which has always been my principal area of interest. I also still have one or more of your - now many days old - posts which I wished to address - at this distance just one or two paragraphs which I did wish to respond to. Most of the remainder, again at this distance, it is probably not profitable to persue especially as we both have our views which neither of us is likely to modify.
