Hello, I'm new here, excuse my english... Are there points in our space? If there are not, as it seems obviously if space was (is) created since big-bang (can points be created?), the consecuences are strong. For example, we deduce inmediately the uncertainty of positions --if there are not points, there are not (x,y,z)--, every function f(x,y,z) is aproximate, the space is not continuos, we are not in R^3 but in Q^n, etc... What do you think? Llorenç Balsach http://www.webcom.com/musics/escrits.htm "The matter-energy is not inside a space-time, but the space-time is a manifestation of the matter-energy"
