Evgenn I have not much time this week. I just added a paragraph below. I will ask this with more detail later:

Matter then is a parallell computer with as much nodes as particles etc. But this is a paralelized version of the idea of the universe simulated by a computer program, with the variation that the computer is the whole universe itself. Life, thus would be a computation over a computation, because living beings compute at the macrostate level, using macrosciopical laws, not at the particule level. Byt I think that the idea of particle computing is wrong. the idea of a simulation trougn steps that represent a new state of every particle is wromg, whether the steps are caculated by a computer or the whole universe. Among other things because time is not a first class citizen in any cosmological theory. I think our observations, that is, life, determine a local time, but that´s all. I think that the best view of the particles according with the theory are trajectories in a static space-time within a manifold where nothing changes. This is the idea of the block universe. Computation at the level of particles is wrong from my point of view. And thus the idea of a computation in a rock does not .refer to the interactions between individual particles. From my point of view my description of a rock as a newtonian computer is just a intriguing curiosity for now. A ballcock perform some computation it generates good outcomes for the humans no matter if the flux of water is intense or slow and thus it may be considered as candidate to be a part of a living being. What living being? It may be part of what Dawkins call "the extended genotype" of the human being. like a car or any human invention. Then a rock have a similar function if this rock is part of a wall in a house, for example. > > -- > You received this message because you are subscribed to the Google Groups > "Everything List" group. > To post to this group, send email to > everything-list@googlegroups.**com<everything-list@googlegroups.com> > . > To unsubscribe from this group, send email to everything-list+unsubscribe@ > **googlegroups.com <everything-list%2bunsubscr...@googlegroups.com>. > For more options, visit this group at http://groups.google.com/** > group/everything-list?hl=en<http://groups.google.com/group/everything-list?hl=en> > . > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
