Fractal or ?? Let consider the well known Einstein Idea of local time disposed on earth (attached to material points). Nobody can forbid me to consider this whole earth (global realtive to earth) as a point again, with only one space-time coordinate (this way is easy of course, but the other seems less ?). Questions : 1) How do you make this transformation and it's inverse ? 2) Can this be seen as a kind of fractal universe ?
