:::::: Well, in Newtonian mechanics, the gravitational field is indeed conservative -- it's the negative gradient of the gravitational potential! But what this means is that gravitational potential energy is path-independent: it doesn't say anything about path-independence any other quantities, and in particular it's not the reason for the path-independence of age. --[[User:KyleT|KyleT]] 15:00, 2 August 2010 (EDT)
