It could be a mathematical run. It is digital some we can use the natural numbers and the successor relation for the first order time of the UD run. Independent subcomputations manage their own "time". Physical time is something else: it emerges in the plural first person perspective.

This of course is not proved, but admittedly required for a materialist.

Apparently, homeotherm animals can be frozen and heated back and still keep even their short term memory, if I remember correctly (!). Experiences with rats suggest this is the case, according to Michel Jouvert (the discoverer of REM sleep). But what I really want to say is this. Even if you were true, or Jouvet false, actually even if our relevant brain state was a quantum state, which when unknown are not duplicable, it would change nothing. I suppose some high level in UDA(1...6) only for making the reasoning more easy. At step seven, all what matters is that there is a level were you are in principle digitally describable, be it the galaxy . The reason is that if such a level exist then the UD will access that state, infinitely often, in many subcomputations, and subsubcomputations. And this gives the fundamental first person (plural) indeterminacy: the fact that each computation, from the 1-pov, more exactly from the obligatory (by UDA('1...6)) 3-pov on the 1-pov, bifurcate or differentiate into 2^aleph_zero histories in the universal deployment. > Switches are in intermediate states, > EM waves are propagating, electrons are diffusing - it is not a > static thing > like a step in a program. I think comp explains the appearance of continua, and the relative correctness of that view. But that "thing", the concrete computer, is a local approximation of the true thing (with the comp assumption). If its representation abilities are locally enough stable relatively to you, it will make possible for the "true thing" to manifest itself relatively to your histories. The "true" thing being the person, not its relative (to you) envelop or description. > > > In terms of Bruno's teleporter, one might say yes accepting that > there would be > a one-time gap in consciousness (ever had a concussion?), but one > would probably > hesitate if the there was to be a gap every 10ms. From the ultimate third point of view, there are no gap, or there are gaps everywhere, that could depend on the topology or topologies you will extract from the numbers. Strictly speaking there are only the natural numbers and their many arithmetical relations. Now some arithmetical relation define or represent universal computation(s), including all finite portions of the universal deployment. From the first point of view, there is no gap. For the same reason that the Everett observer, when measuring, with an {UP,DOWN}-measuring apparatus a particle in the state UP+DOWN, will not feel the split or feel self-superposed. The first person experience is determined by the possible relations you have with your most probable universal history, among already 2^aleph_zero very similar universal histories. Those are just arithmetical relations (assuming ...). From the first person point of view, your concern is not limited to the finite portions of the universal deployment: you are directly concerned by the infinite deployment, in its entirety, and this just because you cannot be aware (UDA 4) of the more and more monumental gaps generated by the UD, or existing in UD* (the universal deployment). I could speculate on the fact (not needed in the UDA) that we can never be unconscious. In the morning, when we wake up, we can have the feeling that we have been unconscious, but that feeling could be a mind construct, a programmed amnesia on the conscious activity of the night. *the* "unconscious" seen as what you are not conscious *of*, could still make sense, but it could be that a person is never unconscious: gaps would be false memories (having some role). Although always conscious, the person could and usually is unconscious *of* many things, of course, like a person can forget things. This leads to the fusion (of person and/or histories) topic. Differentiation and Dedifferentiation.
