  1. Re:I wanted all black holes to meet at same place! on Universe's Curvature Measured? · · Score: 2

    There is more than one solution satisfying a positively curved GR universe with even curvature. One of these would be the solid surface of a hypersphere. Of course the "centre" of the hypersphere doesn't exist in our four-dimensional spacetime. But then, the throat of a wormhole or an "open" black hole doesn't exist in our four-dimensional spacetime either. Even so, it is (as you suggest) fairly unlikely that wormholes or tunnels between rotating blackholes would ever cross each other.

  3. Re:So ... the cosmological constant survives again on Universe's Curvature Measured? · · Score: 2

    I don't know if that's necessarily true. Whether zero or 10 to the -120th, it may not really matter either in terms of consequences or even from a theoretical standpoint. The universe's starting conditions are de facto inexplicable: they have the values they do simply because that's just the way they happened to come out in our universe. Since I know of no theory in which lambda is the result of other still more fundamental parameters, I think this might be one of those starting conditions that (putting the Cosmological Anthropic Principle aside for a moment) took purely random values.

  4. Re:You can't prove flatness! on Universe's Curvature Measured? · · Score: 2

    There can only be two answers to the question of why the universe is flat:

    (i) Some chance combination of initial starting conditions at the big bang which cannot be further explained - this universe just happened to be like that.

    (ii) A universe with a higher degree of curvature would have been unlikely to produce intelligent life either because it would have failed to produce enough baryonic matter or because it would have collapsed too soon for life to evolve, or because it would have cooled down too fast for life to evolve.

    Cosmology is at least more straightforward if you know your Barrow and Tipler ;o)

    Exactly.

    But I should stop short of referring to that global meta-organism as conscious. Consider: Would it have "experience"? Would it be able to act under its own will? We haven't even managed to agree upon what those terms mean when applied to humans. Do *we*, in fact qualify under those criteria, or is consciousness just the private illusion of any data processing system?

    Can a unitary consciousness be composed of other smaller independent but interacting consciousnesses? If so, what does that say about the neurons in our brain? Could Penrose (*choke*) have been right? Personally I don't think so; it would be stretching the meaning of the term "consciousness" beyond the point where the definition becomes too broad to have any useful meaning. It might be better to invent a new term.

    Certainly most people would understand what you mean if you said that the whole world (or any nation come to that) had a "soul". But this is hardly any better.

    To expand upon your point: If a world can have a state of mind, and a nation and a tribe too, then also a city, town, village, family...or even a married couple. Which levels really possess a single soul or consciousness, or even a unique and unitary point of view? Even worse: where are the boundaries which separate one level from the next? Not even at your own skin, because (although I stop short of Penrose's suggestion of conscious neurons) as Dennett points out, the human mind is a Gestalt of independent, monomaniac demons. The identity you refer to as "me" is just a convenient fiction demanded by those demons' shared use of the same body.

    That Gestalt appears to speak for itself only because some of its number have agreed to cooperate to make this possible. But the same can be said of any nation state with a centralised government. Or any group of people with an official spokesman for that matter.

    I don't truly imagine that any collection of people is really conscious. It seems to me that only human individuals are really "in-dividual". Everything beyond that level is just an amorphous field of information processing which doesn't have any well-defined boundaries. Kind of like The Force :o)

    Some may protest that a social group can't constitute a consciousness, because causality resides at the level of individuals. Yet such an appeal would be misleading because just as history can be explained in terms of the circumstances and reactions of individuals, an individual human's behaviour can be explained in terms of stimuli and responses in neural cell assemblies each of which has its own preprogrammed agenda.

    Maybe it's partly the fact of being trapped inside our own heads with a clear "inside=self" and "outside=other" that gives us a point of view and thus makes us appear (privately to ourselves) to be conscious.

    BTW: Sorry for rambling, and I'm especially sorry if my own position appears unclear. I'm still trying to sort it all out in my own mind...

  8. Re:What the experiment is about on Universe's Curvature Measured? · · Score: 2

    ...total energy of the flat universe was and remains zero (this is how you create the whole Universe from nothing without violating the law of energy conservation).

    Correct me if I'm wrong, but I believe it isn't precisely zero.

    A small initial mass on the order of a few kilograms spontaneously generated by a quantum fluctuation, created a small universe (the big bang) in which inflation could then take place. Admittedly, this small mass would be dwarfed by the quantum uncertainty which relates to the presently much larger mass of the universe.

    I just wanted to point out that the inflationary generation of mass out of negative pressure doesn't account for the origin itself.

  11. Re:You ain't seen nothing yet.. on Part One: The Internet Edge · · Score: 2

    I think you have this broadly right except for two things.

    1). I don't think a significant number of people will completely abandon their individuality any time soon. In any case, there would be little reason for them to do so: the technology you are talking about would enable people to communicate at a higher rate, but it would not cause them to merge into a single identity.

    There would be, on some abstract level, a combined entity encompassing the information processing activities of all the intercommunicating computers including human brains. The world as it is *now* fits the same broad description, as we all exchange information via snail mail, books, email, Usenet, Slashdot, TV and the telephone at a somewhat slower rate. But making it faster will not cause this global dataprocessing system to become self aware in any sense which is meaningful to humans.

    2). You missed the most startling outcome of this technology.

    Via an accumulation of implants, interfaces and upgrades/enhancements all the brain's functions will eventually be replicated and improved upon and the little bit of gray matter in the middle will be left as the weakest, slowest and most vulnerable component.

    Meanwhile, there is always a small proportion of people dying of brain diseases or brain trauma.

    A point must come when a suitably wired individual suffering such a tragedy manages to survive brain death or even surgical removal of the whole organ without any apparent loss of function. Such a person might be outwardly normal in every way. At that point we would be forced to realise that the organic brain is redundant and obsolete.

    Where we go from that point is anybody's guess. I just hope we don't all disappear into cyberspace forever, a la Greg Egan.

    I don't know what version you saw, but in the version *I* saw, as Sam drives off into the sunset with his beloved, the faces of Jack (the torturer) and Mr Helpmann (the big wheel) appear. Helpmann says: "He's got away from us, Jack". Sam is still in the interrogation chair humming to himself and smiling vacantly. This strongly suggests (really, it makes it explicitly obvious) that to escape the horror he was being subjected to Sam had retreated into a fugue state and was now quite literally living in a dream world. There is *no* indication whatever that he had been lobotomised. Helpmann's reaction makes it clear that Sam's final mental state was not the result they had desired.
