Now I think there are arguments for the Fine Tuning of the universe. I like Martin Rees' book but I know there are others who disagree with what he said in his book (Just Six Numbers) On another forum I've got involved in a discussion on this topic and I've seen an argument that I think has no proper foundation but I'd like to try it here: Me: "If anyone were to come up with the reasons why the magic constants have to be constrained (or not of course!)within very narrow limits they'd be up for the Nobel prize for physics. Until then all this thread is speculation v counter speculation. However we do know, through simulations, that the constants have to lie in narrow ranges, and that (the fact that they have to lie in narrow ranges rather than the extreme narrowness of the ranges) is remarkable." Strange (to my mind) argument It is no more remarkable than the fact that the range for pi constant is rather narrow. Or for the sum of the angles in the triangle. Or for the sum of 2 + 2. Yet no fine tuner claims that the range for pi values on an Euclidean plane could be wider and it would take luck to have it as it is now. I think this is misapplying geometry to a physics problem and not appropriate. Any thoughts?
