re after years can we say that christian morality is arromdee jyusenkyou cs jhu edu ken arromdee writes simple take out some physics books and start looking for statements which say that there is no objective physics i doubt you will find any you might find statements that there is no objective length or no objective location but no objective physics perhaps you have a different understanding of what physics is if we can t measure anything objectively then the answers we get from physics aren t objective either that s what i mean when i say there s no objective physics sure we can all agree that say f gmm r but that s maths it s only physics when you relate it to the real world and if we can t do that objectively we re stuck of course this displays my blatant bias towards applied science but even theoretical physics gets applied to models of real world situations based on real world observations consider for instance that speed of light in vacuum is invariant this sounds an awful lot like an objective speed of light in vacuum it s an axiom that it s invariant but if the two of us measure it we ll get different answers yes we call that experimental error but it s not really error in the conventional sense in fact if you don t get any that s an error you could argue that the value of c is objective to within some value but i d call that a rather odd usage of the word objective and it opens the way for statements like murder is objectively wrong for all people to within of the total population mathew
