8/10 The thread below has digressed into wikipedia ramblings, so I'll ask here. I read the essay "Intelligent Design: The Scientific Alternative to Evolution" (found here: http://www.intelligentdesignnetwork.org/publications.htm this weekend trying to figure out what ID proponents are actually saying. From reading this I found that the authors were making strawman arguments against evolution and didn't appear to understand physical science or probability. Have you read this essay? Do any ID proponents ever address the weak anthropic principle? Is the 10^-150 probability the number they use in general to show something as unreasonably improbable? -emarkp \_ Math is hard. Big numbers are scary. Someone must have done it. \_ I don't understand what the weak anthropic principle is supposed to explain. I think 'cosmological constant tuning' needs an answer. On a somewhat related note, I read an article somewhere that some experimental data shows that possibly some constants aren't really constant, and change somewhat as time passes. -- ilyas \_ In that essay I mentioned (in the section "The Fine Tuning of the Universe") the authors say: "The force of gravity, the mass of the electron, the charge of the proton, etc. are specific, real values. Were they even slightly different from what they are, not only would life not exist, nothing (of any significance) would exist." They argue that this specifically suggests design. But the weak anthropic principle is that if the universe weren't tuned to life, then we wouldn't be here to observe it. This directly contradicts their assertion--they should at least address it. The fact that they don't even mention it is suspicious at best. -emarkp \_ It is a counterfactual assertion that does not render the current state of affairs any less puzzling. Sure, if constants were different nobody would be there to comment. But someone IS there to comment, and constants ARE the way they are. -- ilyas current state of affairs any less puzzling. Sure, if constants were different nobody would be there to comment. But someone IS there to comment, and constants ARE the way they are. -- ilyas \_ The point is there is a selecting event (i.e. our existence) which makes those constants unremarkable. If we were to observe a universe at random and the constants were amenable to life, that might be something. But our universe isn't a random one. It had to have those constants. -emarkp \_ What you said is exactly right. Our universe doesn't seem to be a random one. \_ Let's imagine a lottery winner pondering what events lead to his winning ticket. He might say: 'well given that I _did_ win, the particles in the Universe must have danced just right so I had to have won. So the fact that I won (at odds of millions to one) is wholly unremarkable.' Really, the real reason it's not remarkable is because millions of people played, so someone had to have won. In other words, lots of Universes makes our constant unremarkable. Our existence does not. -- ilyas \_ But should the lottery winner conclude that someone chose him to be the winner? -emarkp \_ He shouldn't he if knows lots of people played (parallel Universes). Except in our case, it's unclear whether it's cheaper to assume lots of players or a benign lottery agency. I think this is best taken 'offline.' -- ilyas \_ Then your analogy falls on its face. An unlikely event occurs (Bob wins the lottery). It doesn't follow that Bob was chosen by a designer. -emarkp \_ No, it doesn't follow. I wasn't saying it does. As I said, Bob knows lots of people play the lottery. We don't know whether lots of people play or whether someone just decided to give us the ticket. Not only do we not know, we don't even know whether it's more _likely_ lots of people play, or whether someone gave us a winning ticket. That's the point, we have less information than Bob about our situation. But, just as in Bob's situation, the anthropic principle doesn't explain anything, something else does. My point is, despite the fact our state of knowledge is different from Bob's the two situations are exactly the same, and in Bob's situation, nobody invokes the anthropic principle. So we shouldn't invoke it in our case either, because our state of belief shouldn't matter as far as explanations are concerned. -- ilyas \_ (1) It's "an"thropic. (2) It's not invoked to explain anything. It's invoked to show that the reasoning that Life=>special is specious. -emarkp \_ Anyways, what is your answer to the following: P(C=true,L=true) is low, yet C=true and L=true. Are you claiming the above probability isn't low? If so, why? I claim it is low on 'maximum entropy' grounds. Notice how the anthropic principle cannot be used to answer this question, although it is essentially the same: life + constants -> special. -- ilyas \_ I know I'm going to regret getting back into this, but if P(C) is the probability that the laws of physics create a universe conducive to the rise of intelligent life, C=>L. -tom \_ No, P(C) is the probability the constants assume the values they do in our Universe. -- ilyas probability the constants assume the values they do in our Universe. -- ilyas \_ Same conclusion: C=>L. -tom \_ I mean what you say is true, but I don't see how this observation helps. You can conclude that P(C) <= P(L), but how does this address the question about P(C,L)? -- ilyas \_ I mean what you say is true, but I don't see how this observation helps. You can conclude that P(C) <= P(L), but how does this address the question about P(C,L)? -- ilyas \_ The question about P(C,L) is not meaningful, since life will arise if the conditions exist for it. The only relevant part is P(C). -tom _______________________/ Just because C implies L does not mean P(C) fully determines P(C,L). For that to happen you would need C iff L. I don't understand why event implication means questions about the joint distribution are not 'meaningful.' They seem perfectly meaningful (and puzzling) to me. -- ilyas to happen you would need C iff L. I don't understand why event implication means questions about the joint distribution are not 'meaningful.' They seem perfectly meaningful (and puzzling) to me. -- ilyas \_ I was right; I regret getting back into it. -tom \_ Go pee somewhere else then. \_ Non sequitur. We know precisely nothing about any other universes. If you can point to another universe that we can observe that has the same (or similar) constants, that would say something. Since we can't (yet? ever?) observe other universes, we can't evaluate how random this one is. -emarkp \_ Let L be an event 'life exists.' Let C be an an event 'cosmological constants have the values they hold in our Universe.' Your claim: P(C|L) is high. My claim: P(C) is low. That P(C|L) is high does not explain why C is true, though P(C) is low. P(C|L) is high just because of the way conditional probability works. To put it another way, you have to explain why L is true, even though P(C,L=true) is low. Or if you like, you can marginalize out C, and reasonably claim P(L=true) is also low. Or to put it yet another way, you are offering features of the distribution P as an explanation for why we have P and not some other distribution P*. Naturally, that kind of argument doesn't make sense. -- ilyas P(L=true) is also low. That's an entirely symmetric question, and an entirely symmetric argument would be 'life exists because our cosmological constants are the way they are.' At this point, the argument becomes circular, and I can ask a question about the joint event: i.e. why is C=true and L=true, though P(C=true,L=true) is low. Saying 'it's true because it happened' isn't answering anything. -- ilyas \_ No, I don't "have to explain why L is true". ID says P(C) is low, thus we were designed. But that doesn't follow. All we know is that P(C|L) is nonzero, and that P(~C|L) = 0. Also, we don't actually know that P(C) is low in the first place. -emarkp \_ So you are saying that the joint probability of the constants being what they are, and life existing is high? How do you figure that? -- ilyas \_ No, I'm saying that P(~C|L) appears to be low (I think my statement that it =0 may too strong) and that P(C|L) is nonzero. Everything else is being pulled out of someone's rear end. -emarkp \_ Well, you are right that I am making an assumption that P(C,L) is reasonably uniform, but this is a common assumption in science (see 'maximum entropy'). The anthropic principle doesn't answer the 'joint event question.' If you make the argument that P(C,L) isn't low then you have to explain why maximum entropy isn't an appropriate assumption to make. -- ilyas (see 'maximum entropy'). The anthropic principle doesn't answer the 'joint event question.' If you make the argument that P(C,L) isn't low then you have to explain why maximum entropy isn't an appropriate assumption to make. -- ilyas \_ Dear lord...I actually find this conversation interesting. I think I'd better lie down until it goes away. -mice \_ (1) Do we know that P(~C|L) = 0? If either \_ I already retracted the claim. -emarkp \_ sorry, just saw that. the fundamental constants change over time (some evid that they might) or changes in one could be offset by changes in another (perhaps yet unknown constant - there is still that pesky problem of dark matter and dark energy) then P(~C|L) may not be zero weaking the case for design. (2) What exactly is L? Do we really know? We have only one data point to look at. Perhaps other arrangements can give rise to L. (3) Why is it less probable that ID is the answer than say some natural process that produces an infinite number of universes? If you have an infinite number of universes then you will have an infinite number of universes EXACTLY like our own. \_ I find ilyas arguing FOR intelligent design AGAINST a Mormon to be highly amusing. \_ Yeah, because people must always argue from an agenda, and not just follow where the argument might lead. Grow up. -- ilyas \_ ilyas, you always have an agenda. \_ Grow up anonymous troll. -emarkp \_ My agenda is to legislate Jesus into your heart. -- ilyas \_ You're hurting me. -mice \_ Width of universe compared to age of universe compared to speed of light taught me that. \_ http://www.eso.org/outreach/press-rel/pr-2004/pr-05-04.html "contrary to previous claims, no evidence exist for assuming a time variation of this fundamental constant [fine structure constant]" http://www.sciencedaily.com/releases/2005/04/050418204410.htm |

Thx. \_ P(A,B) is a table, with an entry for each possible value combinations of A and B. The numbers in the table have to sum up to 1. Each entry in the table corresponds to the probability of A and B attaining the indexing values. P(A=true,B=true) is a number, the probability that both events happened. P(A,B=true) is a table where each corresponds to some value of A, and means 'probability that A takes on that value and B is true.' P(A|B) = P(A,B)/P(B) where you divide consistent entries. P(A|B) is a table with an entry for each possible combination of values of A and B, where the entry means 'the probability A attains the given indexing value given that the given indexing value of B was observed.' For now you can ignore what happens if A or B range over reals (or take some measure theory). -- ilyas \_ P(A,B) is a table, with an entry for each possible value combinations of A and B.

Life is a powerful phenominon, and there are (at least) two independent instances of it on Earth alone. (e.g. The oxygen based life covering most of the earth and oceans, plus the ferric/ferrous based life found in the heat vents around Seven Mile Trench and lots of mines and a river in Spain) -mel \_ I was assuming life cannot arise without powerful energy sources like stars which an alteration of constants would likely not produce. Why did I assume this? Because life is a 'low entropy' process, and such a process needs a lot of energy coming down to maintain itself. These 'two independent instances' aren't really independent (they arose from a common ancestor) they just use a different metabolic mechanism. Many other metabolism types were used at various points in Earth's life. -- ilyas These 'two independent instances' aren't really independent (they arose from a common ancestor) they just use a different metabolic mechanism. Many other metabolism types were used at various points in Earth's life. -- ilyas \_ My mistake in calling the ferrooxindans independent. Obviously since they have DNA and a biological cell, there is a common ancestor involved. A better point I should have made regarding them is that most people would have trouble imagining life existing without oxygen, but these bacteria do that just fine. I doubt that life in a more generic sense has all that strict a set of requirements on what environmental conditions under which SOMETHING will evolve. -mel \_ Origins are a problem. -- ilyas \_ URL? \_ google "ferrooxidans" -mel \- hello, it is true that is if you tweak certain numbers you cannot have even matter [like without CP violation you cannot explain why we dont have a lot of anti- matter hanging around], while tweaking yet other numbers would not allow nuclei to form, this would would live in a soup of only elementary particles (although possibly some rarely seen ones like the OMEGA- made from SSS). However, there are some free parameters which if tweaked slightly IN ISOLATION we still could get a pretty similar universe in terms of large structure. However it is possible something like the water molecule would not exist. Water is not important to cosmology but it is obviously important to LIFE. If something like the FERMI CONSTANT were different it would change the energy of the fundemantal reactions in the stars which would in turn change their geometry and power spectrum ... so again large con- sequences for "life" and our solar system, but at the large scale and with a "non-antropic eye" the universe may not be too different [there is actually more to the Fermi value, but that is beyond the scope of this discussion]. One may also wish to explore what is the fundamental cause of the PAULI EXCLUSION PRINCIPLE of FERMIONS which allows for elements and chemistry to exist via the AUFBAU PROCESS (I am not very familar with this area of summersymmetry but if the world were made out of the integral spin ss cousins of the electron, photon etc, i believe the universe would turn into one GIANT ATOM/BOSE CONDENSATE). i believe speculating in terms of these free parameters is about the only reasonably way to look at this. you cant arbitrarily ask "what if there was no conservation of mass-energy" ... you have to replace it with something you can plug into equations. You may wish to learn about the CKM MATRIX. ok tnx. universe would turn into one GIANT ATOM/BOSE CONDENSATE). i believe speculating in terms of these free parameters is about the only reasonably way to look at this. you cant arbitrarily ask "what if there was no conservation of mass-energy" ... you have to replace it with something you can plug into equations. You may wish to learn about the CKM MATRIX. ok tnx. [ reformatted - 80x24 formatd ] \_ Water is very important to life on Earth, but in a universe where water didn't exist, there is little reason to believe that no other compound would supply a similar role as a convenient solvent. Removing basic rules like Pauli Exclusion or Conservation of Energy is outside the scope of what interests me. As for learning about the CKM Matrix, I still recall the sequence up, down, strange, charm, beauty and truth even a decade or two out of my last Physics class. The interestng question to me is what the minimal set of requirements are to generate an evolutionary system. -mel \_ Did I say "up down" or "top bottom"? Sigh. This isn't my day for accuracy. Time to go to sleep -mel \- 1. top and bottom have won out over truth and beauty. 2. second, those 6 quarks dont form a sequence ... there are 3 (+2/3,-1/3) charge pairs falling into 3 mass generations. their masses are 1/3 of the free parameters in the std model. 3. speculations based on minor tweaks like if the earth were 10 percent larger or 10% closer to the sun or had a greater tilt or weaker van allen belt etc may be perfectly interesting but those are not really cases of "the laws of physics being different" or "the nature of the universe being different" ... those are accidental details in a way things like the CKM matrix coefficients are not. when you are talking about something like the standard model, "emergent phenomena" is things like stars and elements and chemical phenomena ... it's still a long way from DNA. 4. "life" may have been able to overcome the consequnces of certain fundamental changes [like changing some masses would cause the list of stable isotopes to change, so "life" would have to pick some different chemical pathways, since the relative abun- dances would greatly shift], but there are other changes which are so massive, life obviously could not have evolved ... like if it were not possible to form stable nuclei -> no atoms -> no chemistry. 5. my point was without some knowledge of "the standard model" you cant tell which "tweaks" are "surivivable" and which lead to a "boring universe" and which are some where in between. chemistry to exist via the AUFBAU PROCESS. ok tnx. |
