Please cite source. I liked the discussion that evolution of higher forms of life requires energy sources and sinks. It touches on the idea that if our human species gets off Terra, it expands into the Solar System and how far can that go? In my construction of the future, the development will begin with Lunies and Mars men; progress to Belters who live and work among the asteroids. I don't see so much longterm settlement near Jupiter owing to the radiation environment there; but in time, some Belters move out and begin finding places in the Oort cloud and they become Spacers. All of which is wonderfully accessible to imaginative thinking. (Which is not accomplished by tossing out more or less random quick questions.) In all of this, the life basics mentioned up this thread, all apply. And my guess about how this happens is that over the short run it's nuclear energy, which has to make comeback when we get out into space; but over the longer run, I can see the space environment as good for large thermonuclear power generators. Which being orbital, are easily moved to wherever they are needed. And I'd expect those to be long-lived. Thus the solar energy early life needs, is supplemented and then replaced in our future by hi-tech built resources. Thus the energy basics which must apply, do apply, and there's my construction of a human future in space. Titeotwawki -- mha [sci.space.policy 2009 Mar 05] |

No citation available at the moment, it would take some time to find it again, but it is not a very crucial number. It is a rough estimate, give or take as much as a year, of the time it would take for all plant life to die after all sunlight were to be removed from the planet, and the subsequent amount of time it would take for the animal world to consume itself in starvation and then die. With technology and storage, of course, I suppose human life would last longer, but it would be a dead-end future with no foreseeable renewable food source. This is a very simple scenario which does not take into account the Noah's Ark phenomenon of saving and preserving genetic and seed information of all species. Without it, of course, there would be no future colonization following an extinction event. Be prepared. --tension |

After all, a totally disordered or random system has as it's future only one possible direction, towards more order. As is shown in the study of random boolean networks. I'm afraid your basic premise is incorrect. The system to which you are assigning a random state is one made of atoms. From a reductionist frame of reference that would be correct, all of what you say is correct. But as I said at the start, I was talking about a system perspective. Where order and disorder are defined relative the....output of the system, it's global behavior. Not from the part or component properties. So from a system perspective order and chaos, or simple vs complex has an entirely different meaning. You're still using a linear perspective where order vs complexity is measured, say, on a sliding scale from zero to infinity A non-linear frame would call complex the place where simple and chaotic behavior transitions from one to the other. Such as the very narrow temp range where water is transitioning to vapor. That is the highest level of complexity, at that transition point. Either opposite possibility, water /or/ vapor, is considered simple by comparison to the behavior /at/ the point the system changes state. This is because at the transition point the behavior is a combination of the two states of matter, requiring both fields of science at once to describe the whole. Once on either side of the transition, only one field is needed so to speak. So simplicity is found in either the static or chaotic realms, and complexity is found when the system is equally dominated by both types of behavior....at...the transition point from simple to chaotic. It's at this very narrow transition point where spontaneous order emerges. Requiring a system pushed far from equilibrium, just far enough to persistently reside near this delicate phase transition. And pushed usually by random interactions from outside systems. This narrow transition point is commonly called the Edge of Chaos. Perturbation and Transients - The Edge of Chaos http://www.calresco.org/perturb.htm Attractors everywhere - Order from Chaos http://www.calresco.org/attract.htm linear frame of reference (part perspective) order(simple) chaotic(complex) 0 ---------------- ------------ Infinity in a non-linear frame of reference (system perspective) becomes 0---------- infinity ------- 0 simple------ complex ---------simple static ------- dynamic --------chaotic solid ------- liquid --------- gas classical motion thermodynamics quantum motion So in this view the highest level of complexity is at the point where the system is a combination of both behaviors or states. And also at it's lowest ability to quantify. At the edge. where both classical and quantum like behaviors are entangled. When it comes to order and chaos, atoms tend to follow the laws of thermodynamics, not the behavior of random boolean networks. Well, again you're right, but boolean networks describe the behavior of the ...output... of complex adaptive systems, of which thermodynamics is but the simplest example. "A Boolean network has 2N possible states. Sooner or later it will reach a previously visited state, and thus, since the dynamics are deterministic, fall into an attractor." http://en.wikipedia.org/wiki/Boolean_network An attractor, meaning cyclic behavior, spontaneously emerges. Cyclic behavior is a greater level of order than totally random. And the laws of thermodynamics are pretty clear about the fact that order begets chaos in closed systems, and it is irrelevant whether you are examining very small molecular systems or those of great big astronomical bodies. The concept of absolute zero, in heat measurement, describes exactly what happens in a closed system which is allowed to run down to total chaos and zero order. Those systems do not reassemble themselves spontaneously into ordered systems. But your closed system with zero order is my static attractor. Which could be described like spinning a ball inside a bowl. Sooner or later it comes to rest at the bottom, this is also called subcritical behavior. As opposed to supercritical behavior like a gas dissipating. Or as in gravity vs cosmic expansion. Show me at least one example where this is not the case and I'll be happy to retract. How many examples do you want? When a static system finds itself in an unstable equilibrium (complex) relationship with its chaotic attractor. Then often a third type of behavior spontaneously emerges, called dynamic. As in... solid liquid gas static dynamic chaotic particle motion thermodynamics quantum motion rule of law democracy freedom genetics natural selection mutation knowledge genius imagination producer market consumer science art religion matter light energy pre-invasion Iraq democratic Iraq post-invasion Iraq When a system is dominated by /either/ the static or chaotic attractor, it's behavior is short lived and tragic. But, as boolean networks show, and as any good intuition knows, these opposites tend to attract each other ...they cross paths.. sooner or later. Then life has it's chance. The middle or complex dynamic realms are all emergent. They are all spontaneous creations of the combination of static and chaotic system behavior. Or edge states. You see, a non linear frame of reference provides the essential ability to describe.....every discipline...within a single mathematics. Even the disciplines or art and religion are now under the gun of modern mathematics. Once you learn the universal frame of reference of complexity science. And you know what, suddenly the commonalties among all the countless disciplines become easy to see. There is a simplicity to our reality that can't be seen from a reductionist or from the input side of reality. You have to inverse the initial frame of our scientific method, and /start with the output/ of the whole. For instance, the behavior or output of life tends to follow power law relationships, which in essence is really just another inverse-square law. It's not a coincidence that fitness peak look a lot like gravity wells. Life is no more a fluke than a black hole.

![]() "Martha Adams" wrote in message ... This 'God' concept isn't quite nonsense -- it's an adult recall of what the child guesses before reaching any age of rationality. Since this thinking very often reappears in overt mental health issues, it's not nonsense. It's pathology. Is there nothing you would admit is 'unknowable' or forever mysterious? Does everything have to have a rational explanation? Does the term God need to be defined precisely? If you believe in the big bang, then what came before, if anything, is unknowable and may also be responsible for our existence. Don't you see what the word God means now? God is the most unknowable thing in the universe. The source of our Creation. So when someone asks for a definition of God? It only shows they don't understand the concept. When one dismisses the concept, it's like hearing someone say "I know everything". This is not a word game, the entire point of complexity science is to find...understand...model...and swim in the one place in a system where quantification is most futile, the complex realm. Called K-Crit. The one and only place where rational...precise...repeatable...testable methods utterly fail. IT'S THE ONE AND ONLY PLACE YOUR SCIENTIFIC METHOD CAN'T SEE. So you don't even try to look. I mean if you can't put a number to it why bother you would say. Well, it just so happens, that's the one place where self organization ... CREATION... gets it's impetus. The one place objective methods can't see, and typically dismiss as noise. The source of all creation is found in system properties not part properties. System properties are subjective, part properties objective. So we took the easy route first, down reductionist way. Only thing is that renders the subjective aspects of reality unscientific. The minute you insist on a precise definition, relationship or quantity, the true source of creation becomes invisible. What you have to do is look outside your window at that passing cloud. And admit we're never going to be able to predict it's future shape to any meaningful degree, so why try? Instead, let's try to unravel the system relationships that give that cloud it's life giving abilities. The relationship between condensation and evaporation for instance. Then look at a society, and compare the abstract system structure. And see they are the same, and over and over everywhere you look you see the same system general behavioral properties and structures. Spanning the material, living and spiritual worlds. Then you suddenly realize this universe has an previously unseen simplicity that means life and intelligence are more than likely, but virtually unstoppable. A universe that simple, which creates such complex wonders, must be given a worthy name. A reverent name. A name above all others. It wouldn't be rational to do otherwise. " I Never saw a moor, I never saw the sea; Yet know I how the heather looks, And what a wave must be. I never spoke with God, Nor visited in heaven; Yet certain am I of the spot As if the chart were given." s |
