I'm not keen on your defense of "gut-feel" physics. That only works for people well trained in the field. I'm also not keen on your "I'm not on a campaign to find an answer, I'm on a campaign to cast doubt on current attempts at an answer" approach to things. > >> >>> Has any work been done on alternative theories of gravitation that do not >>> require dark matter? >> >> Yes, of course.

However, what you're talking about is a fit to data, not an ab initio prediction of the theory itself. Newton's second law doesn't predict what forces are in play, but it can tell you about a force you didn't previously take into account, by fitting to the observed acceleration. > > Abhinav Lal > Writer & Investor >> >>> >>> Abhinav Lal >>> Writer & Investor >>> >>> >> >> >> >> -- >> Odd Bodkin -- maker of fine toys, tools, tables > -- Odd Bodkin -- maker of fine toys, tools, tables
