    Why does it seem that this argument is inconsistent with this question:

    I want to form a more coherent argument about this, because I feel that you are wrong, Fraggle. For instance, why can we use math to describe nature? Or, is the answer that the axioms of math just "are"?

    I don't know the answer to this question---I will have to think about this some more.

    It might be possible to prove the impossibility of a RANDOM universe.

    This what Dr. Francis Collins (Head of the Human Genome Project) attempts to do in his recent book the - The Language of God.

    And if the universe is NOT random...something must have given it some measure of intelligent order.

    We can use math to describe a certain class of attributes about anything that has those attributes. Math is an abstraction that does not rely on the existence of a universe for its validity. One plus one equals two, and in all likelihood that has the status of a tautology and a universe could not exist in which it weren't true. But as we get into the more complicated levels of math, for example geometry, we have a model that describes the attributes of our universe (the Euclidean model), but we also have models that describe the attributes of universes that do not exist, such as the Riemannian and Lobachevskian models. (A succinct statement of the essential difference is that in a Euclidean space there is a precise set of "parallel" lines that never intersect, whereas in a Lobachevskian space there is a whole bunch of sets of lines that never intersect, and in a Riemannian space all lines eventually intersect.)

    Nonetheless it is a bit eerie that the universe so often turns out to conform to the logic of our math, as though math is an abstraction of our thinking and our thinking is an abstraction of the structure of the universe since it is a component of the universe. We developed the mathematics of "imaginary" numbers rather a long time ago, and it was centuries before we discovered that this mathematics was needed to describe and analyze electrical circuits. e^iπ=-1 isn't just an exercise in logic, it is a statement of an important principle of physics.

    So the answer to both of your questions is yes.
    • The axioms of math just are.
    • We can use them to describe nature because they just are.
    There you guys go again. Why does the universe have to have been designed, or at least set in motion by some outside force? We know that one plus one equals two, and the truth of that statement is totally independent of the universe. You may be uncomfortable with that hypothesis, but when we subsequently discovered that e^iπ=-1, it confirmed our suspicions that math is something profound, an explanation of how the universe works, and it answers a lot of questions that previously were answered by the ignorant-parent-to-precocious-child cop-out: Because a god did it that way.

    No god decided that one plus one equals two. One plus one simply equals two and no god has the power to make that statement untrue!

    Science is slowly stripping away the imaginary powers of the imaginary gods.

    Pi and e turn out to be extremely important universal constants, but we can make an uncomfortable peace with that because they are at least extremely abstract constants, constants with no units attached. What if it turns out that c, the lightspeed limit, is also a universal constant, even though it does have units attached? We may pursue the theory of relativity for a few more centuries and discover that in concert with parallel advances in string theory, or the eleven-dimensional universe, or whatever new model replaces them, that the units we're using to measure c slough off if the equations are expressed in the proper coordinate system.

    What then? We may eventually find that the universe is the way it is because it simply can be no other way. If there were a thousand universes (yeah as the Linguistics Moderator I know that's a self-contradictory statement but I'm not on my own turf here

    ) we're pretty much certain that one plus one will equal two in all of them and e^iπ will equal minus one in all of them. It may turn out that the speed of light is the same in all of them too.

    Not because some god decided to make them that way, but because that's the only way they can be.

    That 1+1=2 is not the 'order' Collins alludes to in his book - The Language of God.

    Here is a brief summary of his thesis:

    Brief??? It's a bloody two-hour video! Life is way too short for this. Surely you learned how to abstract and summarize in the sixth grade, like all the rest of us. Please demonstrate that skill for us!

    Describe an experiment in which you'd test this hypothesis.

    Surely not!

    For example, it is easy to conceive a universe in which the speed of light is different, however, it is not easy to think of what would have to change for the ratio of a circle's circumference to its diameter to be different.

    So, you're ok distinguishing between your tautologies?

    Youre accustomed to long winded essays...no? It takes less time to listen than to write some of your own posts.

    It is shorter than his book, where he explains the order inherent in the physical universe (he has a degree in physics as well as being a medical doctor and geneticist) and the origins of life.

    Theres really no way to summarize it further, and to do so for my part would be an injustice because I personally find some of it distasteful.
    Heres the Amazon review:

    Consider the following scenario. You are playing five card draw, and in your first hand in the casino you are dealt a royal flush, the probability of which is something like 1 in 2.5 million. Upon seeing this, you proclaim, "This hand is so unlikely, surely the deck must have been stacked."

    Given that you have absolutely no other information about the other cards in the deck, does the statement "This hand is so unlikely, the deck must have been stacked" make any sense? Sure, that's one possibility. Likewise, if you have no other information, is there any way to know whether or not the deck was stacked in the first place?

    The point is that the statement

    is not a statement that is provable. Or, I would say it is not a scientific statement.

    To you I would point out that I can write down consistent theories of Nature in which some of the parameters are different, but in which the universe is still more or less the same. (If you don't believe me, see this paper. They show that one can essentially turn off the weak interactions, set some quark and lepton masses to infinity, and get a universe that is more or less the same as ours.)

    Either way, arguments that "randomness cannot possible explain the universe" always rely on some hidden assumption---in this case it's that the universe is the same everywhere, including the places that we can't see or ever hope to test. There's no guarantee that in those places the physics is different. (If you like, this would be like peaking at the other player's poker hands around the table.) Because we can't test the statement, there is no way to put it on any kind of scientific ground.

    To Fraggle, I would say that the above task is very difficult. If we change some of the properties of the weak force by just a little bit (i.e. don't turn it off, but dial it up just a little bit), then stars burn too quickly for life to evolve. Some properties of physics are VERY sensitive to the difference in the proton and neutron mass, for example. Fiddling with quark masses by just a little bit will screw up a lot of physics. If we make the neutron just a little bit heavier than the proton, then beta decay goes too quickly. In this sense, the universe LOOKS fine tuned. While there is still hope from most of the scientific community that such tunings can be explained away, or that there is caveat that we're all missing, some have resorted to something called the Anthropic Principle, which is sort of the ultimate tautology.

    Again, if you're comfortable with one tautology (1+1 = 2 just because), then you have no right to denigrate others because of THEIR tautologies.

    And one of the proposed explanations is that there are an infinite number of universes and we just happen to exist in the one finely tuned enough to allow our existence.

    And so Collins asks...which requires more faith? One universe finely tuned by some intelligence to support life, or an infinity of random universes?

    Isnt this a universal assumption of physics???

    Are there any prominent physicists who dont make this assumption?

    The question can't be answered subjectively because you can't quantify "faith". Both are leaps of faith.

    This is where Fraggle jumps my case for abusing the word "universe". The visible universe is the same everywhere, but there are reasons to believe that the universe is bigger than just the little patch that we can see. If that is the case, then outside of our little patch the laws may be very different. We don't know, because we can't test them. Our patch doesn't talk to the next patch, so we can't ask the inhabitants of that patch how their laws of physics are different from ours.

    There is another possible explanation. Many universal constants are abstract, derived from mathematics. Yet they occur in nature. Pi is the obvious one. The expression of the Fibonacci series in the leaf arrangement of plants is another. The one that astounds me is e^iπ=-1. That is an equation that is derived from pure abstract mathematics, but it turns out to govern electrical circuits, which are quite physical.

    It may very well be that the ratio of the masses of the elementary particles will turn out to be a universal constant that cannot be violated no matter how cleverly you design a universe.

    Perhaps, but I wouldn't make this a cornerstone of your argument. This seems very unlikely.

    I would also point out that there are some (cf Stephen Hawking http://www.damtp.cam.ac.uk/strings02/dirac/hawking/) who feel that a final theory is not possible. His objections are based on something called "Godel's Incompleteness Theorem", a subject about which I know very little. The essence of the theorem, though, is that for any theory (which must be qualified), there exist statements which cannot be proven BY the theory. The example that Wiki gives is the liars paradox:

    "This sentence is a lie."

    If the sentence is true, the it is false, and vice versa. While the statement "1+1 = 2" is probably provable by the theory of integers, there may be other statements in the theory which are not provable.

    So, the situation seems very intricate. If Godel's theorem holds for the universe, then we cannot truly know the final theory. That is, all statements about Nature as we know it may only be reduced to unprovable axioms, or something. If that is the case, then there is TRULY no way to show if a God exists mathematically, much less experimentally. Again, the best we can do is to set limits on how God acts.

    As posted earlier, Logic is not usable for proving the existence or nonexistence of god.

    Logic is an axiomatic system. What axioms would you use as a starting point? Fundmentalist Xians or Islamics might be willing to start with the assumption that their holy book (Bible or Koran) is assumed to be true, but such an asumption is far more complex than the set of axioms for normal systems of logical analysis.

    The best you can hope for are cogent arguments.

    I'm just gonna add my two cents here for giggles.

    When i studied physics a number of years ago, i was astonished by a very many great things that occur in our universe. I was particularly interested, and subsequently spent alot of time studying, Quantum Tunnelling. I find this part of physics so amazingly unique and uniquely amazing that i further studied physics to learn a great many things.

    A great scientist (i do not know who) once said "The more i study physics, the more i believe in god" and the natural wonder i see and have studied, forces me subscribe to this. There are alot of theories/phenomena out there that fits perfectly into the physical world but to me, cannot have developed purely by chance.

    I know i have offered no proof that god exists or does not exist. I know that there are alot of people out there who will throw away my opinion as mere ramblings of a religious person (which i am not...). But i cannot look at this world and believe for an instant that there is no "Higher being" that has in some way designed the many wonderful and beautiful things i see.

    Adam and Eve, the garden of Eden etc etc are not stories i believe in, creationism is not a theory i believe in. But there has to be something out there that has had an influence on our universe which has gifted us (and possibly other beings out there) with an amazing thing

    the big problems arise when those who only appear as a god to us now due to thier advancement pretend to be god.

    like if we so wished we could veil ourselves using high technology as a god to some isolated primitive tribe somewhere and in all likely hood they would believe it!

    thus if our own future for example wanted to pretend to be god to us,they could quite easiliy achieve that.

    appearances will be deceptive!
