http://www.tc.umn.edu/~janss011/ http://www.tc.umn.edu/~janss011/pdf%20files/harvey.pdf Michel Janssen: "This is the ontological constellation favored by Brown (2005): "I see the absolute geometrical structures of Minkowski space-time as parasitic on the relativistic properties of the dynamical matter fields" (p. 100)......Brown (2005) characterizes the Minkowski metric as "no more than a codification of the behaviour of rods and clocks" (p. 9). Once again, my only complaint is that this characterization privileges rods and clocks. I would say that Minkowski space-time (both its metric and its affine structure) encodes the default spatio-temporal behavior of all physical systems in a world in accordance with the laws of special relativity. Special relativity is completely agnostic about what inhabits or--to phrase it more awkwardly but in a way that may be more congenial to a relationist --carries Minkowski space-time. All the theory has to say about systems inhabiting/carrying Minkowski spacetime is that their spatio-temporal behavior must be in accordance with the rules it encodes." That is, special relativity is completely agnostic about the way in which criminal Einsteinians can trap a long train inside a short tunnel: http://www.youtube.com/watch?v=VSRIyDfo_mY&mode=related&search= and also a 80m long pole inside a 40m long barn: http://www.math.ucr.edu/home/baez/physics/Relativity/SR/barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn." Perhaps criminal Einsteinians can perform those miracles by muttering Einstein's 1905 false light postulate: "speed of light is constant independent of the speed of the source speed of light is constant independent of the speed of the source speed of light is constant independent of the speed of the source...." etc. However now that Michel Janssen has discovered special relativity is completely agnostic, Einstein zombie world will have to abandon any hope to know how long the train trapped inside the short tunnel is or any other miraculous detail. Criminal Einsteinians can just trap long things inside short things and that's it. Pentcho Valev pvalev@yahoo.com
